Summary
     A bored Peter comes across a new kink and decides to indulge.
Notes
     If piss desperation isn't your thing, now's your last warning to back
     out. Peter is 18 here, but I tagged as underage to avoid anyone
     accidentally stumbling into this weird kink fic.
Simple curiosity had brought Peter to the video buffering on his computer
monitor. He’d been scrolling online and come across a thread debating the
weirdest kinks. He’d thought it would be good for a laugh, and most of it was,
but one of the comment chains hadn’t made him laugh so much. Instead, the
thought of “piss desperation” had intrigued him. He certainly wasn’t going to
admit that in the thread or to anyone he knew, but it was true. He’d skimmed
through a few written stories and jumped around a couple videos, but this was
the first one that had held enough of his attention to watch all the way
through.
A man in his twenties was relaxed on a bed in a pretty non-descript room,
already erect at the start of the clip. His face was cut out of the shot, but
Peter could stand to imagine. He was fairly average looking, but Peter’s eyes
were drawn to the obvious bulge of his bladder that interrupted the otherwise
soft lines of his physique. He was squirming with one hand around his already
lubed dick. He squeezed to fight the urge but couldn’t completely stop the
squirming. Once he had a bit more control, he loosened his grip slightly and
pulled down then up slowly. He was breathing hard but kept an agonizingly slow
pace with simple strokes, all the way down to lightly tap his balls then all
the way back up before he repeated the process. He let out a soft groan that
went straight to Peter’s own dick and sent him reaching down to adjust himself
as he hardened.
He’d calmed down the desperation enough that only his uncontrollably quivering
thighs gave away how badly he needed to go. The guy picked up the speed of his
hand early in the video. Peter wondered if it was more to help distract him
from the urge to piss or if he just couldn’t control how aroused he was
getting. Now he focused on quicker strokes along the middle of his cock. He
didn’t stray too high or too low anymore. His breathing had picked up too,
gasping every so often and reminding Peter of his own neglected erection. He
held onto the willpower not to grab ahold of himself.
The man’s pace picked up again, and he was back to pulling his strokes higher,
paying more attention to his sensitive head. He finally reached his top speed,
enough to shake himself and cause the bed beneath him to creak slightly with
each upstroke. His thighs shook more than ever and he couldn’t seem to decide
on one place to keep his feet. His hand was a blur. He raised his hips and
started to fuck into his hand, spreading his legs wider apart. His chest was
heaving with the effort.
He slowed down with a strangled gasp right before a spurt of cum landed on his
abs. Another dripped down onto his hand, and a third joined the first higher up
on his stomach. He kept stroking his softened dick, focusing on the head, and
before long he couldn’t hold back the piss that started spurting out to join
the cum on his abs. He kept tugging, sprinkling piss along his abs and chest.
It dribbled down to soak the bed beneath him, but he kept going until there was
nothing left in his bladder. He breathed hard in the aftermath with a looser
grip on his dick. The bulge of his bladder was completely gone, revealing his
normally flat stomach. After a couple seconds of no movement, the video ended
and looped back to the start. Peter clicked to pause the video, not mentally
ready to watch it a second time.
That was… inarguably the weirdest porn he’d ever watched, but he couldn’t deny
that he was almost impossibly hard. In fact, he yearned to try for himself.
One side effect of the spider bite was a greatly increased metabolism. As a
downside, he went through a lot more food than before. As a plus for today’s
experiment, fluids went through his system just as quickly now. In almost no
time, he had a soda and a tall glass of water in front of him. The goal was to
get as desperate as possible with enough time to spare before he had to worry
about May coming home tonight. It was the summer after his senior year and Mr.
Stark had already gotten on his back for overdoing it with patrols all day at
the start of the break, so he had too much time alone spent being bored. He
wasn’t in the mood for being creative. The video had excited him enough, so
copying it seemed like an easy way to enjoy an afternoon.
He opened a new tab to scroll through YouTube. He clicked on a video and had
finished both drinks by the end. That was easy enough. He made a quick trip to
the kitchen to grab another glass of water, found another video when he came
back to his room, and repeated the process. He gave his bladder an experimental
push with his palm and wasn’t feeling much yet, but he could wait.
It was just past lunch time, and he was alone until at least six. If he wanted
to copy the guy from the video, he’d need a towel or something to avoid
actually wetting his bed and alerting May. He snatched the used one that was
drying from his last shower on his door, folded it in half, and spread it about
where he thought he’d be on the bed when the time came. Would one towel be
enough? He grabbed a clean one and placed it over the first towel to be safe.
He just had to make sure to get those in the washer when he was done.
Preparation done, he sat back down with another can of soda for variety. He let
himself enjoy the taste and the tingle of the carbonation in the first sip
before he distracted himself by catching up with Instagram.
When he reached the posts he’d already seen, he realized he’d zoned out and
finished his drink long ago. He could feel a slight need to piss, but not to
the point where he’d normally leave the room to use the bathroom. He’d honestly
expected this to go more quickly with his metabolism, but it wasn’t like he was
pressed for time. He shrugged to himself and grabbed his third glass of water.
He let himself get distracted to pass the time his body needed.
He’d finished his fifth glass and he was definitely feeling the liquids now. A
light pressure had settled along his abs. Another testing press with his hand
almost made him lose it sitting there at his desk. He pinched at himself and
took a deep breath to reel the feeling back in. His Parker luck kicked in and
the front door clicked open. Fuck.
Acting quickly, he grabbed the towels from his bed and draped them on the back
of his desk chair like he sometimes did after a shower. A few quick keyboard
combinations bookmarked the video he’d been saving for later and closed all of
his internet tabs. He tossed the empty soda cans in his trash bin for good
measure. The sudden worry had done a good job of removing all hints of arousal,
so he unlocked his bedroom door to greet whoever had come in.
Ned was waiting in the living room with a Lego set they’d been waiting to work
on. He’d gotten bored and came over uninvited, as was their usual routine. It
didn’t take long to catch up with each other considering they’d just met up a
couple days ago. Ned poured out the Lego pieces on his bedroom floor while
Peter took a final glance around the room to check for anything incriminating.
Peter consciously kept track of his hands, afraid if he stopped thinking about
their position, he’d find one clenched around his dick to hold back his rapidly
growing need. He couldn’t remember ever having to piss so badly, but he’d
tasted his forbidden fruit in the form of one particularly arousing amateur
porno and now he couldn’t bring himself to cancel his afternoon plans by
foiling all his effort now.
Ned ended up staying an hour, barely long enough to get started on the model.
Peter couldn’t even remember what they were building anymore. He was too
distracted trying to think of anything not even tangentially related to liquids
while pressing his legs together.
Finally, he made up a non-existent Spider-Man patrol to convince Ned to leave.
He was struggling not to grab ahold of himself or bounce his legs to ease the
desperation, but he couldn’t stop the tremble in his thighs without physically
holding them still with his hands. He could see that the guy in the video
hadn’t been overacting based on his own reactions. He wondered if he’d even be
able to last long enough to go through with the original plan. He felt close to
bursting.
He barely managed to act normal while he walked Ned to the door. He flipped the
lock as soon as Ned was out and let loose as sigh of relief. He dropped the act
once he was alone and managed a half-walk, half-waddle to his room while
gripping himself for dear life. He had to let go to refold the towels the way
they were and arrange them sloppily on his bed. He grabbed his phone and took a
second to find the bookmark he’d made from his computer.
He tossed the phone beside his pillow while the video buffered again. He gently
unbuckled his jeans and groaned softly at the relief that came with removing
the external pressure on his bladder. He hooked his thumbs in his boxers and
swept them and his jeans into a pile on the floor. His shirt joined a moment
later. He considered for a moment and decided to make one more run for the
kitchen to chug a final glass of water before he gently lowered himself onto
the bed.
His phone’s screen had gone blank, so he unlocked it and set the video to play.
It took more effort and time than usual with his throbbing bladder distracting
him every so often, but soon enough his cock stood at attention, just as raging
hard as earlier in the afternoon.
He’d spent years learning to be silent to avoid interruption or embarrassment
while he was rubbing one out, but summer break had afforded him much more
privacy once he was old enough to stay home alone, and he’d gotten used to
letting himself be vocal. So, he unabashedly let out a drawn-out groan when he
first grasped himself, knowing just the right amount of pressure to start with
and finding that it felt better than any time he could remember.
With the way his bladder felt, he couldn’t afford to take his time. He pumped
out a little lotion from his nightstand, just enough to make his hand slip
along his length with less effort but not enough to dull too much of the
sensation of skin on skin. He skipped the slower, gentler strokes he tended to
start with and moved straight to a mid-paced jerk with a twist at the top
thrown in after every few strokes. He usually reached a pleasurable sort of
zoned-out haze by the time he reached this pace, but he had to focus on not
letting his bladder fail this time. That just turned him on all the more.
Soon, every stroke brought a gasp or a harsh exhale and he could feel himself
approaching the edge. He let himself pick up the pace with a moan and suddenly,
he was cumming, the results splattering across his stomach and pelvis. He felt
the usual release that he was seeking, but it dimmed in comparison to the
irresistible urge to piss. So, he let go of his control.
Breathing like he really had gone on patrol, he tried to follow along with the
video and did through the first few spurts of piss, but he was too sensitive to
go on and finished with a steady stream after he had to let go of his dick for
comfort. He groaned in pleasure and relief once more at the release before he
sat up to go about the rest of his day.
