Hello, long (long!)-time lurker, first time writer. This originally just came out of an alternate ending I suddenly made one night purely for my own enjoyment. Then I thought, well that was exciting, what if I just started a whole new thing fresh...? And was inspired (by my dick, I imagine) to churn this out. Please excuse any odd formatting. Hopefully I can edit things if need be, this is my first real post here, I have no idea what I'm doing. Anyway, Please enjoy! All credit goes to Kasey (https://www.omorashi.org/profile/223054-kasey/) for the original work: This is basically a fanfiction-y spiritual sequel. Not really authorized in any way, hopefully you don't mind, I really enjoyed the original story! "Parker's Second Ultrasound" Unfortunately, despite my best efforts at clever schedule arrangement, Parker was my second-to-last patient that day, weeks later. “Parker! Come on in,” He got up from his seat in the waiting room and entered, already seeming much more in control than the last time I'd seen him. There was a pinkness coloring his cheeks, but I suspected it was more embarrassment at seeing me again than from expending effort. Hands were calm enough at his sides, he walked almost casually, but there was a visible stiffness in his gait that meant he would definitely love to have a piss right now. I couldn't help but pout in my head. Due to the patient I had after him, I wouldn't be able to stretch out his appointment to devote any extra care today. As much as I longed to keep him here until he was writhing on my table again, I really would have to get a completed examination out of him this time. I was hardly worried about Parker causing any trouble; he was far too submissive and humiliated about his prior accident to complain or even mention it to anyone. But if I brought a patient back for a fourth time after a third apparently failed attempt, a superior or some bean-counter might notice the name repeating. It could be played off, but the game was subtle manipulations, if I wanted to carry on with my brand of fun. "It's good to see you again, Parker," I smiled smokily, teasing, as he shimmied up onto the table. "I apologize I wasn't able to get you in for the last slot today. I know you prefer the privacy." The cute little freckles on his face were nearly swallowed by the burning redness that swept up to his ears. No doubt, he was conjuring images of the last time he had been in this room, on this table, helplessly unleashing his raging piss. He quickly turned away, unable to meet my provocative gaze. Maybe just a trick of the light, but I could have sworn I saw his dick twitch beneath his gray sweatpants. "Oh, um.. yeah. It's okay, don't worry about it," he mumbled awkwardly, shifting in his seat and still studiously ignoring me. Oh, this precious boy. "Well, I'm sure you know the drill by now, sweetheart. Expose that belly, and I'll get you gooped up." Nerves were clearly affecting him, when he jerkily tugged his pants down too far, exposing his cock to the naked air. And my appreciative look. I suddenly realized how much I missed this little playthi-.. my patient. He hurriedly pulled them to the correct height and adjusted himself. Pretending not to see his fumbling, I busied myself getting the gel applicator. I hesitated, then put some into my hand, opting to apply it hands-on instead. If I couldn't have my extra time, I was going to enjoy what I had. I smeared it on, taking extra care to cover him fully, probing my fingers around his bladders' curves and slope. It was certainly firm, but I also knew what he was truly capable of. He was maintaining his composure well, only fidgeting a bit before I was satisfied. But let's see how long he can keep that up... A quick wash at the sink, and back to business. I checked the probe and set to work moving it around on his middle. Before I could plan my next move, I noticed from the monitor that he was just a hair below the ideal level to get the readings required. In reality, this was a meaningless difference. I could see everything needed. But he was technically under... I was just barely able to hold down the devious grin that ached to split my face. Shifting smoothly into my new plan, I put on a puzzled expression, and hummed to myself in mock concern. Parker finally glanced up at me. I shifted the probe once more before humming again decisively and setting it back in its cradle. He was attentive now. "Are we done? That was quick..." He watched, relieved, as I wiped the gel off him with a paper towel. "Nope! You naughty boy, you didn't follow your instructions," I said playfully. "You aren't full enough for what we need." "I, I drank plenty! The recommended amount," he protested. "Sorry hon, maybe you did, maybe you didn't, but it apparently didn't make it to your bladder," I gave said organ a poke, reveling in the wince that followed. “Get those pants back up and... Here,” I handed him a 4oz specimen cup from my supplies on the counter. “We need to get some more water into you. Sorry, best I've got; but it's new, completely sterile. And it's small, so fill this up at least eight times at the drinking fountain in the waiting room and we’ll see how things look after I take care of my next patient.” “I really have to go now! How isn't it enough to- I can't drink all that too!” “I’m sorry Parker, but it's just how it is. I need your bladder at the correct fullness to get a good picture. So it needs to be all eight, just to be sure. Be a good boy, get that water in you, and I promise I’ll bring you back in as quick as I can." "But, but...!" he tried again. "Parker!" I said sternly and grabbed hold of his chin. "You know you need this check-up done, I can't do it as you are, and we can't just keep rescheduling because you don't want to cooperate! That being said, I'll ask... Did you have anywhere you needed to be after you were done here?" "N-no..." he admitted. "All right, good. We're getting it handled today then. Go follow my instructions, while I get things reset for my next appointment. But don't drink too fast! Don't want to get a tummy-ache." I smiled privately. We both knew his stomach was not going to be his main concern in just a short while. The consistent blush coloring his face drained away as his fate sunk in, and was replaced by frightened paleness. He stared down into the empty cup and slowly turned as I guided him to the door. It closed behind him and I set about cleaning the equipment and getting things ready for... I checked the next set of records... 28 year old woman, Sarah Brinkman. - I spent a fair ten minutes getting ready, decent time for Parker to have done as he was told. I opened my door with a friendly smile and announced to the waiting room: "All right, Sarah, I'm ready for you!" "Oh, thank God!" I heard her mutter under her breath as she hopped up and rushed past me into the office. She had her small purse held in a death-grip in front of her crotch and her thighs pressed tight together, making a swushing sound with her leggings. Very tight leggings; with no panty-lines to be seen. Saucy girl. Parker was across the room, starting to fill what must be his final cup of water. I lingered on him a moment, then turned to follow the fidgety brunette. She was already up on the table, leaning forward and shifting constantly. "Good afternoon, Sarah. How are we doing today?" "Mmmmm, afternoon.. Doing fff-fine!" she forced out, fooling no one. "Good to hear! I can see you're ready, so let's get started. I just need you to lay back and lift your shirt a little. And your waistband down to just below your pubic bone, please." She complied and lay back gingerly. Just the same, she grunted when she was fully reclined. " SHIT, " she sucked air through her teeth. "Oh, I'm sorry! I just need to go so baaad!" She moaned, worriedly rubbing her hands on her leggings. Only just resisting the urge to plunge them between her legs. I chuckled amiably. "Believe me, I've seen and heard it all, honey! Don't worry about it." After a moment, she had collected herself enough to complete her instructions, and revealed what she was wrestling with. She had the build of a devoted athlete; medium-small breasts, slim but muscular hips, and she was lightly tanned on her beautifully toned midriff, made all the flatter-seeming by the bloated bulge pushing up below it. Easily the size of a softball and just as firm. On her small frame, it was almost obscene. "My my, you weren't kidding," I commented. She just nodded. "I was keeping hydrated all day... I had my run earlier," A few trickles of sweat escaped her hairline and streaked her pretty face. If I were more into women, I would have been soaking through my panties with arousal. As it was, they were only partially damp. Such a display on this gorgeous woman couldn't be denied all affect. But I did have a job to do, and a particular young man currently bursting with excitement for me to finish, so I applied the blue gel and began the examination. Sarah shuddered hard at the cool touch of the applicator, legs crossed at the ankle and her strong thighs squeezing ever tighter at the probe's light touch on her skin. She was attempting to keep her breathing even and regular, trying to simply endure the pain, but it was quickly turning into short gasps as she struggled to keep herself still and dry. I split my attention between the monitor and drinking in her frantic battle. Unsurprisingly, she was overfull, but I was able to see what I needed from her. Her check-up was for something different than Parker's. Sarah's desperate sounds and the electronic hum of the equipment faded to the background as I couldn't help thinking of how Parker must be doing. How full he must be now. As that extra water I demanded of him trickling down into his already full bladder. Stretching it even further. How he must be clenching his little cock tight, curled up in his seat, rocking back and forth. Or maybe was he squeezing himself, both hands, as he skipped back and forth, potty dancing wildly and praying nobody was going to walk in and see him in such an embarrassing position. A loud groan of distress shook me out of my daydream. I realized I had drifted off staring at the monitor. And I hadn't moved the ultrasound probe for the past minute and was putting extra pressure on Sarah's bladder. She had her fingers dug into the cushion beneath her and one knee raised up over the other in a panic. "Oh dear me," I said, recovering quickly. "I'm so sorry about that, I thought I saw something, had to get a closer look." "Mmm," she whimpered, and only nodded again, face screwed into a tight-lipped grimace, sweating more now. Despite my daydreaming, I believed I'd gotten all I needed from her. She was finished up here and ready to be released. In more ways than one. Right as the probe left her skin, there was a sharp hiss between her clamped legs. The gray material tucked into her crotch became a darker shade glistening with wetness. Abandoning any embarrassment, her hands flew immediately to her pussy, jamming her fingers up between her lips as far as they would go. Despite the added outer pressure, another spurt escaped. A pause. Then a longer one. She moaned loudly in agony. Her legs were held ramrod straight, but her body as a whole was vibrating with effort. Sweat was streaming down her face, plastering hair to her forehead. A third jet spurted out around the finger tight against her pee hole, the longest yet. This girl was racing past her limits and I couldn't stop watching her crash right into the finish line. Sarah swung herself off the table and hopped from foot to foot in a frenzied dance, hair flying wildly. "I have to go, Ihavetogo, please, PLEASE, I have to PEE!" she nearly shouted. "Of course, you're finished, go, go!" to say otherwise would be unprofessional, of course. The squirming young woman pried one hand from her crotch and flung the door open to crash into the wall. Across the waiting room outside, Parker paused in his own dance. He was hunched over, legs twisted, dripping sweat, one hand on his knee and one inside his pants, gripping his cock for all he was worth. Looks like I was right, I though to myself. The head of his cock was held forward in his fist, making a visible impression on his sweatpants. A small dark spot bloomed as his grip wavered in shock at the sudden noise. His wide eyes were locked on the doorway in alarm. Sarah, meanwhile, lurched out and to the left, toward where the single unisex restroom waited down a short hall. However, her legs were so tightly contorted and clumsy from panic, as she tried to run, her right foot got caught on her left and she pitched forward to the floor. Luckily, her honed reaction time was fast enough to throw her hands out to catch herself. She stayed like that, on all fours, for a brief moment that felt like an eternity. There was a high pitched sound coming from her throat, and it was plain to see this was her final effort. I could almost imagine a deep rumbling sound building, like a boiler was rapidly pressurizing until the bolts fired off, seams burst, and blew the roof into space. I wasn't far off. With a sharp cry, her dam finally broke and boiling hot piss gushed from her pussy, clattering loudly on the linoleum floor. It sprayed out of her like a power washer on 11, forcing its way through the sodden material of her leggings as if they weren't even there. The way her hips were positioned, the stream was firing down and behind her, pushing her puddle back past my doorway where I stood gaping. It almost seemed to get stronger as she let loose a guttural moan, the smallest feeling of relief finally beginning in the base of her brain. Then her back arched, her body involuntarily trying to curl in on itself to bear down and mechanically force her bladder to empty faster. She relaxed slightly, then a contraction caught her again and brought her hips forward with a grunt, then again, and again for a fourth time, groaning raggedly with each one. Her own body worked her like a bellows, forcing the piss out in surging bursts. At long last, she seemed spent and the flow petered out. She sat there, hands and knees in a warm pool of her own making, head down, huffing like she had run a marathon. I gave her a moment, then approached and lay a comforting hand on her back. Apparently, that one small touch was enough to break her concentration and trip a hair-trigger deep inside she had felt rising, and a different dam broke. Her legs clamped together with a squelch and she tightened up again, fingers flexing and breath caught fast in her throat. One foot twitched pitifully behind her. She let out a tiny gasp and shuddered in place for a long moment. Slowly her seized muscles released and she swayed, now truly spent. I steadied her around the middle before she could tip over and get a face full of her own pee. I could only squat there and blink for a few seconds. I don't think she or I was expecting that. That piss must have really been something. "Sarah..? Are you all right?" I murmured. She blinked up at me blearily, struggling to get her bearings after such an... experience. "Um, I..." she cleared her throat, still in shock. "I... am so so sorryyy. I just couldn't hold anymore... it hurt so bad. And-and then I... I couldn't....it just hit me... right in front of you... holy shit, just kill me now..." A few tears plinked down into the piss puddle. Gentle sobs began to shake her shoulders as I stroked her back and took stock. The full puddle stretched a few feet out in every direction, more past my office. Her leggings were now basically a complete darker shade, soaked from the pressurized release and absorbed off the floor. And I had almost forgotten the other occupant in the waiting room... Parker seemed rooted to his spot, apparently not having moved since the door first swung open. Just staring in horror, as he still was, at the pretty girl forcefully voiding what he so desperately wanted to as well. He was still clutching at his cock in his pants, but it now jutted forward erect, and his wet spot had snaked a thin line down his pant leg to the knee. As if sensing my attention, he suddenly came back to himself and remembered his complaining bladder. He hunched forward again, renewing his desperate battle, and re-moistening his wet spot with another leak. "Sarah... Sarah, it's okay honey, you're okay," I consoled, and helped her rise to her wobbly legs. "It can happen to anyone. You should have seen our ultrasound training days in medical school. We had to practice on each other for hours!" And I continued a bit louder, "But you feel a lot better now, don't you? Relieved at last. All that pressure gone, you probably feel so much lighter!" I smiled at Parker, who was now kneading his cock to keep his own waters in. Sarah half-nodded morosely, still sniffling. I escorted her on towards the facilities. "How about you get cleaned up as you can in the restroom and- do you feel okay to drive home?" A nod. "All right. And really, you can barely tell at a distance. If you go out the back here, no one will be the wiser, I promise." "Mhmm... th-thanks," she said wetly. And tottered into the restroom. I turned back to take care of Parker, at last. Who was delirious with desperation by this point. His kidneys had done their job superbly and were working through all the water he had dutifully choked down, shoving it through into his bladder until the organ stood out proudly between his hips, taut as a drum. He was standing shakily at the edge of the puddle. He had himself pulled out over his waistband and seemed to be trying to hype himself up to piss on the floor. "PARKER. You put that thing back right now!" I whisper-shouted, feeling like a dog owner with a misbehaving pet. In his strained mind, he thought he could sneakily relieve some pressure into the mess already there. He gave a start as he heard me. And quickly yanked his sweatpants back up, waistband pulled purposefully above his bulge, and immediately pinched the end of his dick again from the outside. "But, I-! I can't wait, I caaan't... " He moaned out piteously, shaking his head back and forth. Yet, he still was. I quickly splashed over and seized him by the shoulders. "You can and you will," I commanded. "Let's get this done, sweetie. You've been such a good boy so far, don't ruin it now." And firmly herded him into my office, making tiny waves in the lake of piss with his shuffling feet. I kicked the door shut behind us and slid the children's step stool up to the table. In his state, I knew he wouldn't make it up himself. Shaking and shivering as he was though, I still had to help steady him. Before he sat down on the edge, I said, "First, we'll just get these out of our way entirely, yes?" Like a flash, I grabbed either side of his sweatpants and shucked them to his heels in one motion, dislodging his hand in the process. He squeaked in alarm and a quick shot of piss sizzled just past my face, which was now at crotch level. His bladder was truly incredible from this close vantage, it was now stretching the whole area between his hips and pushed out a solid inch or so, nearly covering his dangling penis in the shadow it cast. I gave his cock a hard flick as I straightened. "Hey. Do not piss on the tech," I admonished, but he hardly noticed. His eyes were screwed shut and cock pressed between palms tucked tight between his thighs, both to hold himself shut and try to hide himself in embarrassment. He moaned lowly as he forced back a further leak. "All right, now lay down, I'll get you checked out. And then you can let out allll that pee," He nodded, still concentrating, and eased his bare ass on and swung his legs up. I slid his bunched up underwear, pants, and slip-on shoes all the way off and tossed them on the counter. Parker now lay shivering in exertion and cold on the table, naked from the waist down. He had a white-knuckled grip on his cock, sweat oozing from every pore on his body. Bare dancing legs crossed one over the other, then the other way, one knee popped up for a moment, they twisted tight around each other, then stretched out flat; just trying to find a position that offered any relief. Wide eyes tracked me as I got the gel and probe out. I would have to be extra gentle, he seemed fit to pop at any moment. The gel slid smooth onto his heated body and he groaned as the applicator softly kissed his stretched skin. Had he been in a clearer state of mind, he would have long realized that if he was too full for the exam last time, he was definitely too full right now. As it was, he couldn't retain a thought beyond the retention of his piss. I was under no impression I would be able to get anything useful yet either; but I just couldn't help myself not to play it out anyway. It was almost sad toying with him like this, but my nethers swimming in steaming arousal did not care a whit. Gel done, now there was a problem. Two shaking forearms were stretched over the area I needed to probe. "Sweetie, your arms are in my way, I need you to let go of your cock." The look he shot me was pure disbelief. "No, no I can't! It's too much! I can't!" he whimpered, squeezing at his dick rhythmically. "Parker, you are not a child! Adults can hold their piss without grabbing at their junk. Get your hands off! Now!" He choked out half a sob, scrunched his eyes shut, and slammed his arms down to the table at his sides. They quivered there, longing to dart back down to squeeze again. I wouldn't be surprised if his fingernails had drawn blood with how tightly his fists were clenched. With arms unable to help, his legs twined themselves around each other, trying desperately to do it alone. His pelvis lifted off the table, then settled back again. He let out a truly agonized groan. "Thank you, sweetheart," I cooed. The probe came down and delicately traveled its course. I rested my offhand ever so faintly on the base of his bulging bladder. I could almost feel his sphincter fluttering in fatigue, as his cock jumped with each spasm and little squirts leaked out every few seconds. His breath was coming in short gasps, face burning red and shining with sweat, straining himself beyond belief to keep his piss contained with that one tiny ring of aching muscle at the exit of his bladder. I continued swiping across him, relishing his performance, but I finally relented. Despite not once looking at the monitor, I pretended I just noticed something and clucked my tongue, taking the probe away. "Tsk... ... -Oh fine, Parker, use your hands." The latest burgeoning leak was cut off as he rammed his hand over his cock, bending the pliable hose over itself and clamping down on it to stem the flow. "Well, it seems you overdid it, naughty boy. Now you've got too much piss in you." For a split second, he shot me a furious look, resent and indignant anger flaring in his eyes, but it was quickly smothered in a fresh wash of tortured desperation. I continued, "We'll have to let some of that out, so I can check you correctly." "Ba-bathroom?" A faint sparkle of hope glinted in his scrunched face. "No, Parker. Sarah's likely still in there and I won't have you bothering the poor woman." He seemed about to sob. "No, you're going to do it in here. With this," I held up another of the specimen cups from earlier. He either wasn't thinking about how precious little that cup could hold or he was so eager for any relief that he didn't care what size it was, as long as it could receive liquid. He nodded, and squeaked emphatically, "Please!" "All right, but only in the container! You wouldn't want to make a mess on my floor again, right?" I couldn't help but tease. He awkwardly scooted himself off the table as fast as the sloshing weight between his legs would allow and stood on the floor next to it, dancing about like he stood on hot coals. I handed him the cup and he got into position, tucked close to the table in a vain attempt to maintain some level of privacy to do his business. I could have pretended to humor his efforts and look away, but he wasn't paying attention to me anyway. He aimed his shaking cock as best he could, and finally let go. The piss ripped out him, drilling loudly into the small plastic container, which was filled to the brim in scant seconds. He grunted as he tried to pinch off the flow, but the head poking out of his tight fist spat another fat stream onto the floor. And then a second. His body had finally tasted a little relief and it burned to continue. A third hot spurt. His eyes flicked around in sheer panic, looking for something -Anything!- to help him, when he realized five more cups sat on the surface next to him. A measly four ounces were obviously not going to get him to the target volume, so I had laid out all the cups I had at hand. The young man set the full one on the table and snatched up the next to hold ready under his dick. Piss gushed at once into clear plastic. In a stroke of desperate genius, he let his cock hang on its own and grabbed the third cup with his unoccupied hand. Without slowing his stream, he swapped in the empty cup just as the second one started to overflow and set it next to the first one on the table. He continued juggling through them like that until all six cups were on the table, full of steaming urine. After enjoying such a long uninterrupted stream, his bladder shrieked all the louder when he clamped down again. I was almost sure he would scream as well. Doubled over and trembling dick held tight once more. Stock-still and focused entirely on maintaining control, he had to let a short burst out that had managed to force its way into his dammed up urethra. After a long half-minute, a single drop hung shining at the tip, but no more escaped. He managed to heave an unsteady breath as the thundering wave of urgency passed enough for his mind to clear of its blind panic. Parker's bladder still felt horribly full and on the verge of surrender, but at least he could think again. I let out my own deep breath. I had enjoyed seeing that. To my practiced eye, the bulge appeared much closer to an acceptable level now. I joined him on his side of the table to collect the piss cups. But first, I embraced him from behind to run my fingers up and down his chest, "You did so well, sweetie. But you did leak on the floor." He yelped when I gave his ass a solid stinging smack. "I'll clear it off and then back up on the table, boy." We both got ourselves into position, and I was about to begin when... "Parker," I began testily. "You're blocking me again." "I'm sorry! I still really really have to pee!" I huffed lightly and stroked my hand along his upper thigh. "Mmmm... I guess you sure do, at that... Remember what we did last time to help you hold it?" My fingernails traced farther upward. Now I gently massaged his balls, and they began to tighten up in response. "Y-yes..." he answered hesitantly, his mouth suddenly and ironically feeling a bit dry. "Well... get it started then," I prompted, adding a little huskiness to my voice. I continued caressing his sac as I gave his inner thigh a few kisses and a quick lick. His erection began to build, hidden under his hand, until it was too uncomfortable to keep forced down, where he let it out to spring skyward. He kept his hand wrapped around it but seemed afraid to go further. Embarrassment with doing yet another very private act in front of me warred with the visual and feeling of my head so close to his crotch, hot breath wafting across his sensitive areas. A bit impatient, I moved in closer and dragged my tongue on his balls, tasting the salty tang of his sweat. From the back of the young man's throat came a soft moan, different than what I'd heard from him so far today. Just a few more seconds of that and his cock was throbbing hard. Even if he wasn't cooperating, that should block off his piss for a time. "There you go, big boy, keep it in." I straightened and started my exam. When his erection started to flag a little from overriding piss pressure, I moved his hand off and wrapped my own slim fingers around. I had no qualms giving him a few tugs if he wouldn't do his part. The reluctant moans were part pleasure, part pain. Parker's bladder was still aching full, but decently reduced enough for me to work. He was still struggling with it nonetheless. I passed the probe back and forth, taking care to focus where I needed and make sure he was looking up to snuff in there. All the while, I kept a steady stroking of his cock, keeping him hard and the piss locked up. An impressive display of dexterity on my part. Meanwhile, liquid was still getting filtered out by two well-exercised kidneys; the last of the water he had drank earlier. As time went on for the examination, his bladder was refilling. It seemed at an exponential pace, as if the body was making up for lost time now that it knew some space had been made. Parker was becoming increasingly agitated, his reddened cheeks and sweating had kicked back in with force. Between my hand on his cock and his bladder inflating, he had two burning needs fighting for release. I slowed my stroking as I struggled to make out what I could through the increasing bladder size. It was near impossible by now, but I had experience and this was the final chance for getting this exam done. Suddenly, he grunted and a squirt of piss jumped from his hard cock and drenched my hand in hot urine. "Parker, I haven't finished yet! You hold that piss in, young man," I snapped. "Sorry!" He panted. "But I have to go- ... -fucking bad!" The blush had reached his ears again, painting him all in fire engine red. One heel was juddering a wild tattoo on the table as his legs shook uncontrollably. He shivered and shook all over, tearing between desperate need and frantic desire. His cock was fiery rod in my hand, which I now held still, simply squeezing him closed. I could feel his muscles clench through it, pushing and flexing against my hand. Holding back the surging ocean of pee or trying to reach an approaching orgasm, I couldn't tell. I doubt he could either. He let out whimpering moans with each panicked breath. His face was twisted into a horribly pained grimace as what felt like gallons of piss rammed on the same gate that his churning balls wanted to blast cum through. A hot prickling sensation climbed up his spine to the back of his head, making him tingle all over as his body felt ready to, he was sure, literally explode. The feeling spread out and down to fill his trunk and limbs with crackling, numbing energy. Fingers lost feeling while they dug hysterically into the cushion beneath him. During this rising turmoil, I kept my eyes on the monitor to get the last imaging of his raging insides. I could barely see at this point, but finally it was done. He was hale and hearty, no problems to be seen at all. I raised the probe off his squirming, writhing body and let go of his steely cock. "Okay, Parker. Looks like you're all good. We're done," I declared. His watering eyes darted to me and took a long second to grasp at the words that sluggishly worked through his waterlogged brain. He almost seemed to comprehend for a moment, Then all at once, his stomach muscles tightened and he half sat up as a long and powerful silver jet shot up from his erect dick. It nearly reached the ceiling before it all crashed back down again, dousing him, the table, and me. The stream paused a moment, as he strained to stop, but it geysered up regardless, arcing down again to splash all of us. He let out a cry. Abruptly, the torrent dwindled and cut off, as if something had closed off its path. Cock rigidly twitched a few times, but nothing escaped. He was tipping over the edge. Parker flopped back to the table and gripped tight onto the sides of it. He began to tremble as his ass cheeks clenched and stabbed his rock hard cock toward the ceiling. His brown eyes bulged and crept into the back of his head. His mouth dropped open and chin jutted out, for only a hoarse croak to escape. At last, muscles in his groin contracted forcefully, and a blast of cum erupted from his dick. It flew straight up to splatter down onto his own shirt. Hips bucked in spastic jerks with each mighty spurt that blasted cum with unbelievable power to splash down around him. I counted at least eight, reducing in volume with each, but the last was longer and clearer. Internal plumbing was forced to immediately switch gears as his bladder now exerted all its strength to void. His wildly confused system took that great forceful pressure as a sign to begin another round of orgasmic contractions. His hard cock continued to jolt, but now shot piss up into the air in quick bursts like he was cumming it out. It obviously felt so, as his head was still thrown back in ecstasy and his whole body spasmed. Each fat burst hissed as it escaped his highly pressurized pee hole. Eventually, his cock heaved a final time and the rhythmic shower was over. Parker lay boneless on the table, chest heaving as he could finally start to catch his breath. His eyes were closed in euphoric bliss and exhaustion. It looked like his bladder bump was near smooth again, but not completely flat even now. I couldn't be surprised, that was hardly a normal way to empty a bladder. Obviously he wasn't feeling it urgently, though; he almost seemed dead asleep, if anything. My white jacket had more than a few wet patches decorating its surface. I had tried to step back a bit when the fireworks had begun, but there was only so much room to escape that steamy golden shower. Although, it wasn't very golden with how hydrated he had been, and you could barely smell a hint of it. I slipped my outer layer off to avoid any more soaking into my scrubs underneath. My panties were also wet, but... that wasn't pee... I just had to give my slick folds a quick rub to partly satisfy the aching tingle. I shivered, then collected myself and went to stand at Parker's side with my arms crossed under my breasts. I waited there for a time, shifting my weight a bit, until his breathing began to normalize. I softly cleared my throat. His eyes peeled open, one at a time, and he seemed to have trouble focusing on anything. Slowly, vision cleared and he could see me staring down at him, a few random locks of hair wet and matted down to my scalp. One hung dangling in front of my face. The fiery blush returned once more, this time pure horrified shame and embarrassment. He knew what happened. My things squeezed together briefly as I bent forward at the waist. I leaned in close to his face and grabbed his chin roughly. "Parker... dear boy. I thought I told you... not to piss on the technician," I snarled. Wide brown eyes flicked between my own blue in terror. A feral grin bared my teeth. "You're not getting off from that scot-free." I pushed him away and stepped back. I slipped out of my shoes and stuffed my socks into them. Dainty feet patted on the cold floor. Looking him right in the eyes, I then hooked my thumbs into the waistband of my scrub pants and slide them down slowly, revealing the jet black panties underneath. An extra shine in the gusset where they were soaked with my arousal. I pressed a needed hand up against myself for a moment, then slid the panties down as well, pushing my ass out provocatively. Now I stood, hands on hips, naked from the waist down, just like Parker, who stared intently at my neatly trimmed bush. He swallowed hard and his penis jumped once as it tried to get hard again, but was unfortunately too wrung out to perform so soon. I showed my teeth again and climbed up onto the table to straddle his middle. There was just barely enough room to perch with my shins on the soft cushion to either side of him. "Ready to get yours, Sweetie?" I asked. Throughout this long day of excitement, my own bladder had filled significantly from my usual intake of fluid and a skipped bathroom break. As Parker was losing control wildly just then, I felt my urge ramp up quickly to be very uncomfortable. My own middle had grown large and hard in sympathy with my last two patients' desperate battles. Though not quite to the same degree. And now I could feel it absolutely aching to gush from me, onto the young man held captive between my smooth thighs. I sat my ass down heavily onto his pelvis, pressing down on his bladder and tucking his cock into the groove between my cheeks, aimed toward his feet. He grunted in surprise and discomfort. I gave him a last predatory look, and released. The piss rushed out in a surging river onto his stomach, hissing and splashing, rapidly re-drenching his damp shirt. A long moaning sigh whooshed from my mouth. Ohhh, this felt heavenly; the relief! It was not a stretch to see how Sarah could have came earlier just from pissing out her massive load. I could feel my bladder deflating as the days-worth of pee flowed powerfully from my pulsing pee hole. I gave an extra push, increasing the already vigorous flow into a roaring deluge, striking off his skin and flinging droplets into the air. The flood spread across his body, then off the table, in waterfalls crashing to the floor. A husky groan tumbled from my lips. I rolled my hips a bit, grinding my gushing pussy onto his abdomen. Then I heard the spattering sound of liquid striking the vinyl cushion behind me. It seemed his blocked bladder had finally relaxed again. I fancied I could feel the hum as the piss coursed through the shaft nestled into my ass. We both sat there, giving the occasional pant of delicious relief as we pissed out all we had for the next nearly forty seconds. Our streams slowly died out. I bore down again, forcing the last of it out in a hard squirt onto his stomach. We both breathed. The fire that had been burning inside me for the last few hours blew up into a roaring inferno, as if the pee I just released had been the last thing quenching its fury. My right hand flew straight to my hooded clit like a heat-seeking missile. Fingers rubbed frantically, using my piss and personal lube to fly ever faster and harder. Breaths came fast and hard as the heat spread up into my chest and face, nipples poked out against my bra. I spared a glance for Parker, seeing him goggle at the tech that had just emptied her bladder onto him and was now madly bringing herself to orgasm, perched right on top of him. He'd seen me naked and was currently wearing my piss, so he could get as much an eyeful as he wanted, far as I could have cared right then. My hips moved on their own, grinding my lips desperately against his pelvic area. I was already so nearly there. The sun-like heat in my body built rapidly to a supernova that finally detonated behind my eyes as a scream of ecstasy tore my throat raw. I saw stars as I blacked out for a moment and only distantly felt myself fall forward onto Parker's soggy chest. My muscles spasmodically twitched as I lay there, one hand still glued to my crotch, giving my clit a few gentle rubs to ride out the pleasure. A peaceful five minutes passed while I gradually drifted down from my incredible high. I couldn't help but let out a long sigh of satisfied pleasure, then lifted my head to give Parker a half-lidded, dreamy smile. The corner of his mouth quirked up slightly then back down, he was plainly unsure of how to feel about all of this. At length, I clambered off of him and stood next to the table. I adopted a professional tone, in hard contrast with the cool air I could feel caressing my damp labia. "Okay, we're all finished up here. Thank you for being so cooperative today. Your results will be added to your records; you can check them out online if you want in your Patient Portal. Have a great evening, and if you have any further questions or concerns..." I took his face in my hands and darted in to mash my lips against his. Mouth parted slightly in shock and I slipped my tongue in to dance briefly across his teeth. I released the suddenly breathless young man and pulled back. "..please don't hesitate to schedule another appointment." And there we are. Hope you all enjoyed, (while a little hot under the collar, if I did it right). I'm not sure I got the characters quite true to the original, but eh, it is what it is. Fanfiction, after all. Also please excuse any awkward bits of inaccurate medical tomfoolery, I am no doctor. And have never even had an ultrasound myself, for that matter. I am also not a woman, so hopefully the intimate descriptions were close enough to accurate and, at the least, not cringe-inducing. All righty, off you go now.

Hey so I've been thinking a bit more on this lately- Any of you guys ever feel the intense desire to experience peeing as a different sex? Like, biologically? Because there are some significant differences. Some are obvious, but others, less obvious, as I've learned through the years. We have physical differences that mean we can pee in different ways, but there are also so many other interesting things to consider to. So to start on a personal note, when I was a kid I was always really jealous of boys because I wanted so badly to be able to pee in a way that seemed so much more free than what I could do. I wanted to not have to pull my pants completely down, to be able to control my stream, to pee through small openings in emergency situations- (e.g. a bottle if I'm in a car on a freeway, or out a window because I'm stuck in a room for some reason, etc.)- or just for fun even, let's be real. I wanted to do so many things my anatomy just wasn't capable of but I couldn't and it bothered me. It wasn't until I entered adulthood that I realised this was mostly due to having a pee fetish. As a teenager, I did actually teach myself to pee standing. It still had its obvious limitations and took some time to master but it was GREAT- have not done it in a while though I will admit so I would probably mess it up if I tried now- and I have some experience with STPs- also great, but again, there are limitations. Even with all this, I do still find myself wishing I could experience peeing with an actual penis- I also wish I could experience cumming with a penis though too sometimes (no where near as badly though)- I have a hard time achieving orgasm and didn't have my first until I was 21- I feel it would be a bit easier it I had a dick sometimes haha- but I could very well be wrong about that 😅 don't get me wrong though, I do love my vagina and its surrounding areas. There are definitely some advantages there 😅 but speaking of, anyone also curious about climaxing as a different sex? I'm sure at least some of you are! Haha Anyway, I think its quite common to be curious about how it feels to pee as the opposite biological sex, even for those not into pee like all of us here, and I do remember doing some reading a few years ago that actually explained that the physical sensation of needing to pee differed between male and female bodies. The difference is apparently only slight, but I find that super interesting! And it just makes me more curious. But I also wonder, what is it like for people who don't fall into the category of male or female? Is the sensation for biologically intersex people different at all? Like, somewhere in between? There is a lot of variation in what is considered intersex so I imagine it would vary with the people depending on, I'm guessing, external genitalia, but I could be wrong. Its also interesting that even outside of our biological differences, there are different social expectations for different genders, and this differs in different cultures, as does how we physically position ourselves to do it. This is also something that- as I only know second hand through research and talking to friends- greatly effects transgender people. I can't claim to experience their experiences first hand at all as I'm not trans, but I've listened to several trans men, women and nb people talk about their experiences when it comes to peeing. There are a lot of things they are often made to think about that us cis people tend to take for granted, even those of us like us who think about peeing A LOT. So yeah, I know I dragged on a bit, but how curious are you guys about experiencing the physical differences? Or what about the social? And does anyone else have any interesting stories on being intensely curious or super jealous over it, like how as a kid I was jealous of boys?

I'll go first. I'm a 26 year old straight male for context. I'll start by telling you what my favorite flavor of omo is: genuine uncontrollable accidents brought on by a truly bursting bladder and no chance of using any facilities to relieve it! General naughtiness and power pissing work very well for me as a sort of foreplay, but if you make it the main event, I don't think you're into the same flavor of omo as I am. I'd plan so many things to do! Obviously the climax would be sex while bursting, but we've gotta do plenty of stuff before that! I'd start by announcing on the app that I'm using that I'm into pee desperation and bladder torture so the poor girl knows what she's getting herself into. Of course, we'd be strangers who met online and are curious about our pee fetish. I'd like for our first meeting to be late morning so we can have lunch and take full advantage of the unlimited refills offered by whatever restaurant we visit. After lunch, we'd probably go to a park or something where we can be outdoors but still be able to slip away into rather thin privacy for when the moment arrives! I'd just love to go bird spotting, dog petting, and just general outdoor socializing while our bladders fill to dangerous capacities! Since I've got a bladder of steel, I'm sure she'd burst before me, and we could make this into a power pissing show! When she truly can't wait anymore, we'll diverge from the trail we're on and hide behind some shrubs or whatever while she demonstrates just how far she can send her stream into the air! Then we'd head back to a cheap hotel room with two beds where we can do as much damage as we want to the bed and all we'd have to worry about is a cleaning fee. A pool is a must, since we'd bring sports drinks and hit the pool all afternoon! Lots of flirting, feeling each other up, but no nudity or sex yet for obvious reasons. For an evening dinner, I'm thinking an outdoor restaurant with the wooden overhangs and lanterns all over! We'd once again take full advantage of the unlimited refills and drink as much as we safely can! Once done with dinner, we'd drive back to the hotel with our rapidly filling bladders! I'm aware I'd likely have to drink at least a large bottle of water ahead of time to get my bladder truly full before my partner bursts all over the floor... One of the cons of a steel bladder that holds almost 2L... Arriving back at the hotel, we'd watch TV and engage in massages, followed by teasing and a lengthy foreplay session as we reach max capacity! Once we truly can't wait another second, I'd coat my dick in aphrodisiac lube and send my throbbing dick the whole way in! Neither of us are allowed to pee until we both orgasm together, resulting in the ultimate synchronous peegasm that I've only ever managed to experience once... Although I get peegasms rather regularly, it's a matter of compatibility to get a woman to peegasm with you. I've gotten lucky with this once when casual dating about a year ago... Just because we've peegasm'd doesn't mean we're done! We're gonna keep having sex until our bladders are empty! Given the fact that I'd just peed inside this girl, I'd have a vaginal cleaner ready to go. Don't want her getting an infection from any urine left up in there... Then we'd shower and take the other bed for a good night's sleep. What happens next is up to us. If she wants to stay together, that's AWESOME! If not, oh well, it was technically a casual service. Thank you for reading. I'd love to hear about your current fantasies! No need to match my flavor of omo, just be yourselves in your responses! Daredare205's best!

Hi, so this is my first time writing and I can't guarantee that whatever this is it will be pursued fervently, but I want to do something a little bit more creative with my thoughts regarding my sexuality and this scenario has played out in my dreams enough that I want to start with it. Warning, there will be sexual content but not in every chapter, and there will be lots of nudity, but the nudity will not always be sexual. This is not an omorashi first story either, and although omorashi will be included because it is a fetish of mine, it will not be featured in every chapter nor be a major plot point, at least at the beginning. I also have a mild form of Asperger's syndrome, so I feel that I will be able to create better characters that are more similar to me in the way I think, as opposed to neurotypical character that are often difficult for me to grasp. I will initially keep all characters above 18, however if it seems safe to do so I will include ages 15 and up, not because I am particularly attracted to people that young as a 20 year old cis straight white male, but more because I am particularly attracted to people who haven't quite figured out their sexuality, are shyer, and retain youthful attitudes, and this is easier to write in with younger characters. But for now I will stick to 18. I'd appreciate feedback if possible! Chapter 1: Elisa and Saturday Night at the gym Elisa had just started her first year at her university. Although far from her home in New Jersey, she was excited to begin a life of her own and adventure to new places, both physically and mentally. She had grown up in a very religious household, and although everyone in the household was practicing, her parents were good enough to her that they were not too overbearing. Her father was Puerto Rican and her mother was Dominican, and they had met in English class shortly after each of them moved to the USA. Elisa was the oldest having turned 18 last week, and she had one younger sister who was starting 8th grade at age 13, and a brother starting 4th grade at age 9. Although she loved her family very much, the day to day ruses in her household were difficult to manage at times, and she was looking forward to a change of scenery. Elisa's life was complicated as lives should be. There was nothing terrible, tragic, or traumatic about it but life is existentially hard to comprehend, especially in Elisa's case of a mild form of Asperger's syndrome, which gave her a depth of knowledge about a plethora of topics, including politics, geography, public transportation, art history, and really almost anything. Some people considered her to lack personality and be emotionally stoic due to the vast majority conversational interactions being infused with random facts and snippets. But apart from how she might be perceived, Elisa is a very emotional person. Well, not usually outwardly although she does cry from time to time in her bedroom. But like most people with Asperger's, Elisa had chronic depression. It was nothing severe and a manageable mental illness, but it made her feel even more isolated in the way she sees the world. Her quest at this stage in her life is to understand the world as best she can from observation and curiosity. At home she frequently took trips on the PATH to go to New York, and starting in high school she got a bike that could transport her to many medium distance places in North Jersey. But because her family was poor, they could not afford a car, so Elisa did not have a driver's license. That was okay for her though, because she was content with the current situation. For Elisa, life is hard, but the joyful moments make it worth living. As a practicing and believing Catholic, Elisa was well versed on the acts that should be avoided to prevent sin. She was not naïve to the nature of sex, but rather discouraged from participating in anything too promiscuous. Her mother had taught her about it when she was 9 in anticipation of menstruation, and since then she has read quite a bit on the topic and understands human nature when it comes to sexual matters. She has been catcalled or stared at more times than she could count while in public, and while these definitely bother her, she has not been protruded from participating in activities she loves because of it. However, as much as she understands sex from a knowledge standpoint, Elisa is rather unpracticed when it comes to understanding her own sexuality. In high school she also participated in an activity called drum and bugle corps or "drum corps" for short, and while there she had to get used to the idea of communal showers. Being naked in the presence of other girls her age was something she was used to and could tolerate, and as a result she was very comfortable in her own body. There she also discovered that she is mostly straight with perhaps a slight curiosity towards women. But her alone time is limited at her house, and because of the religious nature of her household, she does not want to risk anything about her sexuality being found out by her parents. The only time she ever gets time to herself is in the bathroom because her bedroom is shared with her sister, and she has a habit of taking long showers for the purpose of getting herself off. She knows of at least one fetish of hers, that being omorashi and pee holding. Though she has done it herself a few times, she finds herself most turned on when she sees guys struggle to hold it. It is this that gets her off half the time, whether she is reading or watching erotic material on her phone in the bathroom or just in the shower playing. However, she has not yet had a boyfriend, she has not yet seen a guy naked, and she has not often gone to any parties with people her age. Her parents seldom had to worry about Elisa's doings outside the house due to her Asperger's making many of the risky activities unappealing. Elisa hoped to change some of this at college though. She hoped to get a boyfriend, though she didn't want to force it, rather have it happen organically instead. She also hoped to see a guy naked at some point and/or attend a party of some sort, not to be risky with herself, but instead to observe. This really was a new stage in her life. Elisa had just enrolled in a small-ish liberal arts college in upstate New York near the Adirondacks (this is no particular real life school, I'm basing the school size off my own but I don't want to reveal where I am enrolled, so I picked the Adirondacks because the setting feels right). She got in on scholarships, both for her intellect and her status as the first in the family to attend college. The first week of classes have gone well so far, and the weekend has finally arrived. Elisa spent most of Saturday playing games and watching TV with her roommate, Jordyn. Her roommate and she also did some homework, but after a while they had both gotten tired and decided to move onto TV. This first week, Elisa had discovered that the fitness center was open 24 hours. One simply needed to tap their card and they were allowed in. The same was also true for the pool, however you needed to prove your ability to swim in order to go in without a lifeguard. (There was a multi campus lifeguard standby program so that appropriate lifeguards could be notified if the cameras showed something in which someone needed to intervene. If it was required, there was a button that could drain the entire pool at a high flow rate to provide air to any drowning victims. There was also a breathalyzer that would lock access to any inebriated students). Elisa took the test on Thursday and she now has swipe access to the pool for 24 hours. She found that exercising at night was the best way for her to be active and blow off steam. Fewer people were working out at midnight, making any semblance of social anxiety rest easy on her. She would typically arrive to the gym at 11:30, run on the treadmill for 20 minutes, do weights for 15 minutes, then go to the locker room, change into her swimsuit, use the pool for 15 minutes, come back to the locker room, shower, change into her pajamas, and head back to her dorm to go to bed. She had worked out every day this week except Wednesday, and she used the pool on Thursday and Friday. Her routine was beginning to set itself in and she was starting to get used to the schedule. It was 11:20 on Saturday when Elisa got ready to go to the gym. She got changed into her workout clothes (a purple tank top, white sports bra, gray yoga pants that cut off at the thigh as well as neon yellow spandex boy shorts underneath), and was about to say bye to Jordyn until she realized Jordyn was passed out watching TV in the lounge. Elisa walked by Jordyn, out the door, and over to the fitness center. She was carrying her bag with her swimsuit and pajamas, as well as her large water bottle. Her towel and shower supplies she kept in a locker at the fitness center. On her way over to the gym, she heard lots of voices and screaming all around her. It was yet another party night on campus, and although Elisa was curious, she persisted to the gym. She arrived to the locker room and dropped off all her nonessential items for working out. She realized she needed to pee but then a thought occurred to her: she hadn't indulged herself at all since arriving to campus, mostly because she was rarely ever alone. Perhaps she could play a game with herself and hold her pee as long as she could while working out so that she could release some sexual libido before heading back to her dorm. Consequently, that's what Elisa decided to do. She laid all of her belongings in her locker except for her water bottle, phone, earbuds, and face towel and walked out of the locker room toward the gym. Elisa drank about a third of a 1.5 liter bottle before she started running on the treadmill. 5 minutes in she started getting cramps and realized that she really should have stretched if she were to drink that much. Cramps aside, she made it through all 20 minutes and began to feel a slight twinge in her bladder. The gym was fairly sparse with only about 10 people working out, so there was no need to wait for any equipment. Elisa drank another 300mL or so before starting her quick weight routine. She did her biceps and shoulders with moderately heavy dumbbells (for her size and gender), and then moved onto the tricep machine. Elisa drank another 200mL before the triceps, followed by another 200mL after. It helped that her body needed the water, so it was absorbed into her system quickly preventing bloating and other discomfort. Elisa usually finished her gym portion after the triceps, but because she was feeling so mischievous and because her bladder was starting to give her warning signs, she fathomed another idea: she would do a few reps of the seated knee raise machine to challenge herself. Elisa walked over to the machine, set the weight at the right level and began the reps. Around the 7th or 8th rep she felt another twinge in her urethra that lasted a few seconds. She could feel the fluids building up and the pleasure mounting. As she raised her knees on the 8th rep she shivered and shuddered as her need to pee was ringing the doorbell in her brain. On her tenth and final rep, she let out a soft moan, uncharacteristic for her as she tends to be quite quiet in public, before finally relaxing. She didn't need to go so bad that she was in danger of spurting, but the experience was scary and exhilarating nonetheless. It wouldn't exactly be accurate to say Elisa was dry either, as the garments that covered her nether regions were already fairly damp from sweat since the treadmill. But perhaps her boys gotta were slightly damper because of the juices that may have escaped as her labia parted and lubricated itself. After her indulgence with the leg raising machine, Elisa was ready to return to her locker to prepare for the short swim. On the way over, she finished her final 300mL and refilled the water bottle. She was thinking about how excited and antsy she felt about what she was doing, being in public was especially energizing. She passed a guy who was walking into the gym and couldn't help but bite her lip at the small protruberance visible in his black running shorts. She had never seen a bare penis before except in images and some rated R movies, but she was yet inclined to lay her own eyes on a real one. Wouldn't it be something if I could catch one while I was here today. What if I were to walk into the locker room and see a guy just standing there playing with it? Elisa thought to herself. Alas, this fantasy lived up to its designation as a fantasy, and she arrived to an empty women's locker room as usual. Usual, however, was the baritone audiation emanating from the right side of the locker room, where the toilets and showers were. She realized that she could hear any conversation coming from the men's side, and the their toilets were likely opposite the women's as the conversation seemed to be more of an echo. Elisa discovered the vent in the wall that carried the sound she out her ear up to it and listened in. "Yo, you ready?" said one guy. "Nah man, Imma take a piss first. Them white claws gotta come out one way o 'nother, and I ain't be barfin' today" said the other. Elisa noticed that the end of this clause seemed slightly louder than the beginning, indicating that it was directed closer to her. "Aight man, 'll see ya inside" the first replied. Elisa heard a door creak and some footsteps walk toward her. The vent she was at was in the southeast corner of the room if north were the direction you face when you walk in. She heard some nasal breathing near the east side of the women's room, the west side of the men's. She then heard the soft patter of the guys pee in the nearby urinal. It then coalesced into a solid tone indicative of a stream. Elisa couldnt ignore the urge to touch herself, and began to rub her damp yoga pants. Her need to pee was also slightly heightened, but not yet to the point of bursting. The stream in the urinal dragged on and Elisa kept rubbing herself through the fabric, feeling the pleasure of hearing a guy pee this close. The stream kept going and a small spurt escaped Elisa. She had trouble convincing herself not to continue the pleasurable feelings, but finally the stream tapered and Elisa calmed down. She then heard footsteps walk away and the door creak open and shut again. Ew, thought Elisa, if you're going to be that hot you should at least be hygienic about it. She inspected the squirt both visually and with her nose, and decided that she better get to the pool before she bursts and ruins her fun. Elisa removed her sneakers and socks and walked over to her locker, ready to begin her final exercise before sexual ecstasy. ____ Sorry to leave it here, I intended to stop at a slightly different point but my hands are getting cold from typing and I want to have something posted before I continue so I can get some feedback. Let me know what you think!

It was around 1:30 when Undyne and Alphys arrived back at their new apartment on the surface. The 2 had been drinking at a local bar near there building and needless to say where a bit hazy. Alphys had sipped on a sweet cocktail all night while Undyne had drank 4 beers throughout the night to prove how much alcohol she could drink before she got tipsy to the patrons at the bar. Undyne and Alphys both took their showers after they arrived back at the small apartment and slipped on their pajamas, afterwards they decided to watch some TV. Alphys and Undyne sat on their couch as they slowly became drowsy. Alphys asked to cuddle and Undyne humbly obliged. After about 35 minutes of watching the show Alphys stomach began to act up and made a gargly sound. Alphys bolted up and said "ugh.. alcohol goes right through me! I really need to poop!" Undyne giggled and jokingly said "and don't take too long!". Alphys waddled to the bathroom with her hands over her butt releasing cute little farts as she walked, Undyne giggled. Undyne layed on the couch, eventually slipping into a shallow sleep. About three hours later, Undyne awoke from her slumber and looked around the room. The looked at the clock and saw that the time was just about 5 am. She looked next to her and realized that Alphys was not on the couch with her anymore, "she must have gone to bed" Undyne mumbled to herself drunkenly. As her eyes started to focus she was hit with a sharp pain and pressure in her abdomen. "Fuck!" She exclaimed rising from her sleeping position. As the cogs turned slowly in her hazy mind she started to realize what that pain and pressure was. The 4 beers she had drank early that night had finally settled in her bladder and where now making themselves known. Undyne waddled to the bathroom door with her webbed hands clasping her crotch. She realized that the bathroom light was still on, this she thought was strange as her and Alphys where very curdeaus to turn the lights off in there apartment so there landlord didn't get mad. Then she heard something coming from the bathroom, an anime on autoplay and her girlfriend Alphys snoring heavily, she did go to sleep, but not in the bedroom. Alphys was a heavy sleeper and and even heavier drunken sleeper and Undyne knew this. Undyne banged on the bathroom door but to no avail. When she moved her hand to bang on the door she felt a warmth hit her mew mew boxers. She made a nervous grunt and then swiftly placed her hand back on her crotch. "Alphys please wake up!" She cried but the yellow Dino did not budge nor acknowledge Undyne. Undyne looked down at her bladder, it was swollen and throbbing sometimes awful, she clutched her crotch harder and twisted her scaly legs into pretzels. She knew she didn't have much time left and there was no way she would be able to leave the spot she was in without risking leaking more. Undyne has been standing at the bathroom door for about 5 minutes now and her bladder felt like it had a heartbeat, sending out rhythmic waves of pain to the poor squeeling fish girl. Undyne continued to bang on the door as she grunted and squealed with intense discomfort. She then felt the small wet spot on her boxers get biggers. She gasped as she started to realize that he was losing this battle. as the waves came, her bladder began releasing spurts of alcoholic urine into her boxers at a steady rate, what started as a small stain, has grown into a decent sized puddle in her boxers. Undyne knew she had to accept defeat, sometimes not in her nature. As she stood there pondering the night and everything that led to this moment the rhythmic spurts became a steady stream. Her bladder muscles retracted and a thick stream started to pour from her boxers, forming a yellow puddle on the ground. She was nearly crying as she had never felt so weak and not in control before but at the same time she felt incredible relief. As the puddle underneath her grew she stopped clutching her crotch as it was doing absolutely nothing to slow the flow anymore. She then fell to her knees, panting like a tired dog and blushing like she had never blushed before, as the hot stream of urine finally ended. Undyne the Undying had just pissed herself. Whether it was the alcohol, the moonlight or something completely different Undyne started to feel something she had never felt before. The warmth of the urine In her boxers was rather erotic to her in the moment. She thought back to sweet relief she felt as the finally let go and just the thought of it sent waves of lust down her spine. Undyne decided to turn a bad situation into a good one and took her scaley fingers and jammed them inside of her pussy which was surrounded by thick red pubic hair. It made a gross gushy sound but she didn't care, she started thrusting her fingers inside of her as she took deep breaths of her own filth. She began to moan like she had never moaned before, a certain primal moan she had pent up inside of her for ages. She placed her other hand on her swollen clitorus and began rubbing it all while still fingerings herself at a steady pace. After about 2 minutes of heavenly masturbation the great warrior released a great and powerful moan as she reached orgasm, falling back into the puddle of piss and twitching on the floor. Undyne sat there, pondering everything she knew about sex, but she didn't care, she was satisfied. Now she just needed to clean up before Alphys wakes up, she thought to herself. --------------------------------------------- Hi I'm the author of this here fic! I had this idea in my head since I played Undertale in 2016 for the first time and I finally got around to turning it into an actual fic! This is also my first ever fic, however I still hope you enjoyed reading it as much as I enjoyed writing it. With summer finally here, expect more fics in the near future! I have an idea for a Toriel bladder denial fic, so expect that soon! Also don't mind the edits, that's just me fixing and added things lol!

Explicit Content His watch said that it was still only six o’clock, when Steve awoke the next morning. The sun was just coming up, though, so it was already too light for him to go back to sleep. He unzipped the tent flap, and crawled out onto the sparse grass which grew in the sandy soil here. Being alone on the island, he slept naked, and wouldn’t bother with any clothes until later, when he set off for the beach on the mainland. Camping here overnight was fine, but it wasn’t very practical to stay here during the day, unless he wanted to spend an entire morning lugging easily-prepared food supplies in and out of the boat. There were ample cheap eating places near the beach, making such effort unnecessary. The sea was reasonably calm, without much of a swell, and the breeze was blowing towards the mainland. As long as things didn’t change, the trip across should be no harder than usual. Steve made his way slowly down the slope towards the water, veering to his left to take himself down to the rocks which marked one boundary of the island’s small, sandy beach, which lay still further to his left. As he reached the rocks, he stopped briefly and contemplated the breaking waves, some five feet or so below him. Then he continued along the top of the rocks, walking very slowly in the general direction of the beach. He soon came to a place where it was possible to walk down a gently-sloping rocky outcrop, onto the rocks whose bases were being rhythmically thumped by the swell. Turning, he followed the slope down, and stood looking once more at the waves, the spray from which was now beginning to land on his naked skin like fine drizzle. He stood there for several minutes, doing nothing except watch and feel. His penis lost its flaccid appearance, and began to swell. A couple of times, his brow furrowed and he drew in his breath sharply, bending slightly at the waist as a dribble of urine pattered onto the rocks. Abruptly, he turned to his left once more and carefully descended a natural rocky staircase which took him a little further away from the sea, but towards some rock pools. As he approached the first pool, he stopped walking and stood motionless, his erection swelling further. He bent slightly at the waist again, and this time his urine escaped in a much stronger, if brief, spurt. His erection was now full-on, and with a sigh of contentment, he wet himself. Closing his eyes, Steve smiled dreamily, enjoying the sensation of emptying his bladder in such an uncontrolled fashion. After he had stopped peeing, he remained standing there, his penis fully erect. Steve decided to resist the temptation to masturbate. He continued on his way across the rocks to the beach. The sea was warm, of course, and he waded in until he was chest deep, dunking himself all the way under the water to give himself a thorough wash. The beach wasn’t very long, but it was quite deep, and was bounded on both sides by a pair of rocky headlands. It was more like a cove than a bay, in fact. Steve had approached it the long way around, via the rocks which were now to his left, as he made his way out of the sea. The direct route, which he was now going to take back to his camp, went straight up the beach and over the narrow dunes which lay between here and the hill. As he made his way up the beach, Steve noticed something lying on the sand, about halfway up, near the rocks to his right. The shape of it reminded him of a dolphin, from this distance, and he felt a pang of sadness. Had one of the creatures beached itself here in the night? If so, how had it managed to get so far beyond the tide-line? He turned towards it, wondering if it might be still alive. Whether it was or not, he was going to have a hell of a job dragging it into the water on his own. But the shape didn’t look quite right for a dolphin, as he began to approach it. There was no dorsal fin, and the shape of its back looked wrong, especially near the head. Then he was close enough to see it clearly, and he stopped and stared. It was another mermaid! How strange was that, seeing two in two days? Was she dead? No, her stomach was moving slowly up and down, as if she was breathing. Maybe she was asleep, then. Did they sleep on land, or in the water? Who knew? Until yesterday, he thought they were a myth. * Nerissa was on a beach. This was the beach where she’d met the human man. This time, she wasn’t desperate to pee. This time, it was deserted except for the man. She was kneeling in front of him, as he sat on the odd-looking support where he’d been sitting before. Her hands were clasped against the front of her tail, but not for the reason of the previous time. She was playing with him, coyly hiding her arousal from him. As he looked down at her hands, she moved them, revealing her vaginal flaps, which were open in excitement. The man stared at her opening, the desire in his eyes making her feel even more excited. * Steve continued his approach, but much more cautiously now. If she was asleep, he didn’t want to wake her, and if she was awake, he didn’t want to scare her away. She was certainly very human-looking, he observed. At least, the top half of her was. The rest was a lot like the rear half of a dolphin, which is what had confused him. Now that he was close enough to see her properly, he couldn’t take his eyes off her breasts. If you couldn’t see her tail, you’d swear she was a naked woman. The nipples and aureola were exactly like a woman’s, as was the torso all the way down to her navel. Below that, it was quite different. The pink skin of her abdomen faded gradually into a pale, dolphin-like grey/white colour, just like the underside of one of those creatures. She seemed to have hips, of the same general shape and proportions as a woman, but that was the extent of the resemblance of her lower half to a woman. The part of her tail that he could see — what would be the underside if she was the right way up — was flatter at the top than a woman’s pubic area, and it was obviously a single limb all the way down. There was a slight bend in it, about halfway down, making it look as if she had a single knee-like joint there. * Nerissa suddenly noticed that the man was naked. She hadn’t seen that before. She looked down, and saw how erect his penis was. A sudden longing took hold of her. How she wished she could feel that long, hard member inside her! As if knowing her thoughts, the man leaned forward and reached a hand towards her vaginal opening. Nerissa arched her back to present herself fully to him, hardly daring to believe he wanted to explore her depths. * The area between her knee and her human-like abdomen fascinated Steve. Roughly where a woman’s pubis would be, there was a small, closed slit, about two centimetres long, running in the head-to-tail direction. Her skin seemed wet around it, as if some kind of liquid had been seeping out. A short distance below this was another slit, a little more than twice as long, which was slightly everted, revealing glistening, pink flesh around a gently-pulsating opening. A similar distance below this was a tightly puckered orifice. Steve stared at the wetness around the topmost of these orifices. That mermaid yesterday had been holding her hands in about that position, and had made it abundantly clear that she needed to urinate. Had this one peed in her sleep, then? The wetness certainly made it look like that, as did the streaks down the sides of her tail. Well, why shouldn’t she pee freely? It wasn’t as if she was wearing clothes, and the sea would soon wash her clean. * The man ran his finger around the edges of her vaginal flaps, stimulating them. Then he inserted his finger into her vagina and began moving it in and out. Nerissa’s excitement increased, as the man’s finger slid ever more rapidly in and out of her vagina. * The mermaid stirred, moving her hips upwards slightly, and Steve glanced nervously at her face, thinking she was about to wake and find him staring at her. Her eyes were still closed, though, and he relaxed slightly. * Faster and faster, in and out of her vagina. Nerissa could feel her climax approaching rapidly, as his finger stimulated her. In and out, in and out. The pressure in her bladder was no greater than before, but the urge to empty it was rapidly becoming irresistible. It was a different urge than the usual one, though; a sharper sensation, focussed on her sphincter rather than her bladder, and accompanied by an alternate slackening and tightening of her sphincter muscle. The slackening and tightening was rhythmic, pulsating in time with her vaginal contractions. * The mermaid moved her hips again, arching her back a little more than the last time. Steve transferred his attention back to her pelvic area, wondering what was happening. He noticed that the longer of her two slits was wider open than it had been, and the pulsating inside it was much more pronounced. A suspicion of what he was witnessing formed in the back of his mind. * In and out his finger slid. In and out, in and out. Slacker and tighter her sphincter gripped. Slacker, tighter, slacker, tighter… Ohh! Her sphincter twitched fully open, then closed immediately, shutting off the flow in the most deliciously agonising way. It opened again — spurt! — and closed. Opened — spurt! — closed. She was coming. It was the most wonderful sensation known to any mermaid. * The mermaid’s hips arched upwards again, yellow liquid arced out of the small slit, splashing onto the lower half of her tail, in a spurt lasting perhaps a second, then her hips began jerking up and down rhythmically, the larger slit began opening and closing in spasms, and the yellow liquid began spurting out in a series of much shorter spurts than the first one. As her hips continued to jerk up and down, her right hand moved to the large slit, and she pushed a finger into the folds, moving it in and out rapidly as the yellow liquid splashed against her hand. Her breath was coming in very human-sounding gasps, now, and she was tossing her head from side to side. Her eyes were still closed, though. There was no doubting what he was seeing: she was having what looked like the most enjoyable orgasm in the world. Steve watched, spellbound, his penis rigid with desire, as her hips jerked and she spurted urine. Then, all of a sudden, it was too much for him, and he grasped his penis, pointed it down towards the sand at his feet, and joined her in a moment of pure ecstasy. She continued to jerk her hips and spurt urine long after he was spent. Finally, her back arched upwards in a much bigger heave than before, and her urine fountained in a single, long spurt, before she finally flopped down, spent. Her eyes fluttered open. She smiled languidly at him for a moment, then frowned as if confused, before opening her eyes wide and staring in disbelief.
