That night, a group of four pokémon were running from the storms that had befallen on them. They found a house where they could rest. It was an inn, ran by a gengar. The four pokémon were an odd bunch: a garchomp, Barros; a gabite, Silva; an amped toxtricity, Bispo; a low-key toxtricity, Castro. They were a family, but both Castro and Bispo were adopted by Barros. Silva is Barros' only biological son.
They entered the inn and walked towards the counter at where a gengar was sitting behind. The gengar seemed pretty happy for having four clients at once. He greeted all of them with a handshake, which felt pretty unusual. Surely, he received other clients. Did that gengar greet all of them with that same energy?
- So, how much does it cost to stay one night? - asked Barros.
- Not much, just 45 poké - said gengar.
- That's pretty cheap... - said Bispo.
- It's also all we can pay - said Barros. - We can continue our way under that storm; we might get sick, specially you, being half-electric.
Castro blushed, as he was also half-electric. He felt that he was a bit of a bother to the team, since he lacked the attributes to be a good explorer. He would rather stay behind a counter like gengar all day. Either way, Barros paid up and they walked to their room, which was shared. Each room had two beds and two hammocks. The cheerful and upbeat gabite, Silva, ran to one of the beds and hopped on, falling on it belly first.
- So soft! - he said, much satisfied. - Come here, Castro!
Castro walked to Silva and sat on the same bed, being hugged by Silva instantly.
- You two, I think, can sleep together - said Barros. - Bispo, do you have a preference?
- I want a hammmock -  said Bispo.
Barros, then, took the remaining bed. Gengar knocked on the door and entered.
- Hello - said the host. - I came to give you some room service.
Gengar was carrying some food and juice with himself. He put the jug of juice atop a drawer and the food dishes he gave one to each pokémon.
- Since you guys are the first costumers in such a long time - said the gengar. -, you get some special treament. Make sure to tell your friends about this place!
Castro shuddered and pinched uncut soft penis. Gengar noticed, but said nothing. Castro noticed that gengar had seen it. Gengar grinned devilishly to Castro, nearly making the toxtricity wet himself on the spot. The gengar then left. Castro had to pee and he was the only one so far to notice that there was no bathroom in that bedroom.
Time passed by... It was approaching their bed time. The jug of juice was then empty. Even Castro had drank a little of it. Suddenly, a lightning striked outside and the lights went out.
- Perhaps we should now sleep - said Barros. - No sense staying awake with nothing to do, specially now that the lights are out...
Gengar, now holding a candle, knocked on the door again, saying from the other side:
- I forgot to tell you that there are no bathrooms in the bedrooms. If you need to pee, you will need to find the bathroom at the end of this corridor, okay?
- Fine - said Barros from inside.
Silva and Castro were hugging each other after the lightning strike. But, as the night went on and sleep got the best of them, they were all soon asleep with the sound of rain outside. However, Castro's sleep was bothered by a damp sensation under himself. He realized he was wetting the bed. He immediately pinched his half-erect uncut penis, stopping the flow forcefully. He was so full that he was aching in his midsection. Castro hopped off the bed and surveyed the damage. He made a small, very small puddle on the mattress. He squeezed his thighs together and released the penis, now that he was in control again. The urine that remained trapped in his foreskin seeped out.
Castro then walked to Barros and woke him up. Barros was fully erect, also due to having to pee really badly. He had a hemipenis (dual penis, if you may) that came from inside a slit.
- What is  wrong? - he asked to Barros.
- I really have to pee - Castro said, then confessed: - I even wet the mattress a little...
- That's not good - said Barros. - I also need to pee a lot...
Silva, who was asleep, as well as Bispo, hear the commotion, sitting up. Both of them were erect between their legs, due to the pressing urge to urinate.
- What is going on? - asked Bispo.
- I have to take Castro to the bathroom - said Barros.
- I have to go too! - yipped Silva.
- Fine, we all go together - said Barros, getting up carefully.
They didn't know what was going on with their bodies, because all of them felt really full. Castro's bladder felt painful even. Bispo and Silva were also quickly getting to that point. Was the juice spiked or something?
Once everyone was ready, they left the room they were sleeping in and ventured in the corridor... but it seemed much longer than before. There were countless windows showing the world outside. The rain was pouring with no sign of ending. Every once in a while, a lightning struck nearby, causing Castro to nearly lose his urine. All their penises were erect. Barros and Silva had hemipenises that protuded from their slits. Bispo has a cut penis, while Castro was uncut. Castro could even feel his foreskin getting damp with droplets of urine that left his urethra, but could not make it past the prepuce.
- I really have to go... - Castro moaned.
- Don't worry, we can make it - said Barros. - We just have to get to the end of this corridor.
Time went by quickly, however, and the corridor only seemed to get longer as they walked.
- What is going on? -  asked Castro.
- This must be some sort of psychic power or ghost trick - said Silva.
- Should we go back? - asked Barros.
They looked back. There was no sign of the door that lead to their room either... They tried to call for help, but it was no use. They were trapped in a loop.
- This is scary - Castro said, beginning to cry.
They were holding their penises, which only seemed to get harder, both from the urge to pee and the touch they were giving to it.
- We can do it - said Barros, cheering them on. - Let us just continue...
While they resumed walking, Castro yelped:
- I can no longer walk!
Barros put Castro on his back, carrying him.
- I'm sure this is the work of that gengar -  said Barros.
- Why would he do that to us? - asked Bispo.
- This is scary! - complained Castro.
They kept walking the corridor that seemed to be infinite while the rain rattled against the windows. Castro, who had already wet the bed a little, was having the worst time of them all. His penis was pressing on Barros's body while he was being carried. Barros felt droplets leaving Castro's penis. Castro was biting himself, trying to hold it in. He was teary-eyed and under a lot of pain. Suddenly, he lost a gush, wetting Barros.
- Sorry, dad - said Castro, trembling.
- Don't worry, just do your best.
Barros, however, now that he was wet with his adoptive son's urine, felt his bladder contracting really hard. He stopped walking and squirmed his legs together, prompting Bispo to grab his adoptive dad's penis to prevent urine from coming out.
- Thanks, Bispo - said Barros.
In the meantime, however, Castro kept struggling. He lost more urine, while trying to hold it, pressing his penis hard against Barros' body in order to hold it. But he kept losing urine nonetheless, which, in turn, was making it harder on Barros to hold it in. Further, his urine was dripping on the floor, adding to the agony that the family was already feeling due to listening to the rain rattling on the windows outside. Castro had lost half of his urine. He whimpered and his tired sphincter could no longer stay closed and he was losing droplets and shorts burts constantly. The only thing he could do was to slow down his accident. Eventually, despite his best efforts, he was empty. But the rest of the family was still holding it.
While still taking Castro on his back, Barros noticed that his son's erection was starting to pulse and leak someting else a little.
- Castro, you should walk now - said Barros, noticing his son's arousal.
- Right - said Castro, hopping off and realizing that Barros had noticed that.
Silva was squeezing his penis with both hand-paws now. There was urine in the base of his penis, right behind Silva's iron grip. The gabite was feeling horribly full and all that rain outside was making him feel a lot of pain in his bladder. In fact, his tummy seemed bigger than usual, due to his bladder being so full and taut that it was forming a bulge. He looked like he just had a pretty big meal.
- This hurts so bad... - said Silva, complaining.
- Don't remind me... - said Bispo, who was in the same situation.
Castro was blushing somewhat, still hard due to feeling embarrassed. He wished he could masturbate and take care of that, but his dad would not allow that then... Silva was also erect and would drip every once in a while, when a strong bladder contraction tried to force the urine out, causing pain in his urethra. He had to soften the grip every time that happened and allow some urine to seep out. The interval between contractions was getting smaller. Silva eventually fell to his knees and groaned. His penis was pulsing and purple due to the tight grip. Barros noticed.
- If you need it so badly - said Barros. -, then you can pee against the wall.
- This is not our house, dad - said Silva.
- But, if you simply are in too much pain to even walk, do it. You might hurt yourself if you continue.
Silva got up with help from Castro and nodded. He walked towards the wall and proceeded to piss on it, making a large puddle. The amount of urine inside Silva was astouding: it produced a five-feet-wide puddle and took 3 minutes to end. The puddle reached both walls of the corridor.
- I don't know how long I can hold it in for - says Bispo, the last one standing besides Barros, the dad.
- If you let go, I won't be mad - says Barros.
- But it will be embarrassing... I'm holding it in because I'm the oldest of us, not counting you, dad. I don't want to be seen as a little kid.
- If that's how you think...
They continued. Finally, the door seemed to be getting closer. Silva and Castro were still very erect and Castro was even panting a little. That situation of having just wet themselves and now watching the two strongest pokémon they knew of struggling against their urge to pee was arousing both of the youngest siblings.
- Is this something we are supposed to like? - asked Castro to Silva.
- I don't know... - Silva answered. -, but I sure have a raging stiffy right now.
They giggled to each other. Unlike Castro, Silva was cut and could rely on a foreskin to pinch the dam shut. He had to press down on his penis until it became purple. Suddenly, Castro tripped and fell.
- Ah! - he yipped.
Bispo looked back and went to help his brother to stand, releasing his penis in the process. While helping, urine began to drip out. Silva squeezed Bispo's member, preventing it from leaking any more urine.
- Thanks, bro... -  says Bispo.
- Don't worry about that, I can hold this all day - said Silva, smiling.
Silva could feel, under his hand, that his brother's penis was swollen with urine. Silva's erection throbbed and began to leak pre. Watching the scene, Castro began to leak again as well. Fearing that he would have a hands-free orgasm, Silva released his brother's penis. In doing so, Bispo lost more urine, crouching. His body was in a lot of pain and he decided that he would better let go as well... He sighed deeply and let go where he was crouching. Silva and Castro watching lustfully, both eager to touch themselves, but resisting. That felt like a different kind of desperation. Bispo's bladder could hold some eight liters of urine and it took a loong while to get everything drained. Barros was the only one still holding now. The dad needed to be a role model for his children, both natural and adopted.
Barros had a code of conduct: he was not to masturbate in front of his children. He also encouraged them to do the same. The pressure in his aching bladder was such that it was causing pressure on his prostate. If Barros were to squeeze his penis to stop himself from peeing, he risked having an orgasm. So, he was doing his best to hold it in hands-free. His erection was really strong, pulsing and leaking somewhat, though not urine. He had a sex flush across his face and was panting. His bladder kept trying to void, but the strong dad kept himself from leaking urine, trying his best to be a role model. Castro, Bispo and Silva were feeling sorry for their dad, knowing how much pain he must be feeling. Barros, however, endured all the same. Finally, they reached the door to the bathroom.
- Finally - said Bispo.
Silva went ahead and tried to open it. But it was locked. Barros pushed his head on the door and clawed at it, trembling, squeezing his legs together, but daring not to touch his tingling member. His bladder began to contract again and his sphincter weakened a little, causing a short burst of urine to hit the door in front of them. He recalled how all of his three sons lost the battle against their urine, while listening to the sound of the rain outside, feeling his body aching in every muscle. He could swear he could even feel more droplets of urine entering his bladder, thanks to his busy kidneys and the liquid from earlier.
- Dad... - said Castro, worried, but also aroused.
All of them were at their horniest, except for Bispo, who was just worried for his dad. Barros, Silva and Castro were in another world of themselves: Silva and Castro were so horny that they could mount each other, while Barros was giving into the feelings of arousal inside of his body, if only that could make him hold longer. None of them could think straight, so none though about destroying the door. Another surge of urine left Barros, then another. The surges were becoming more frequent. Finally, despite Barros best efforts, the sphincter was too weak to keep itself fully closed, causing constant seeping whenever the bladder contracted. The sphincter was numbing and opening up more. After three minutes in such state, Barros gave up and urine flowed freely: about 15 liters of urine well-saved. Castro grabbed his dick to jerk it, but Bispo stopped Castro, remembering that his dad would not like that. Silva was squirming and biting his hand, trying to not cave into his own sexual urges as well. Finally, after letting everything go, Barros knelt on his massive puddle, panting, feeling so good after letting it go that he forgot completely that he was sexually frustrated. He even lost his erection and his hemipenis was going back into the slit...
Now that they had lost it and that the bathroom was locked... they resolved to go back to their room and sleep the rest of the night. Furthermore, Castro and Silva were nearing breaking point after the experience. If they didn't reach their room soon, they could make another kind of puddle on the floor. Same about Barros, who has been several days without an orgasm. While they walked towards the room, hoping to relieve themselves in private... the door to their room seemed to get farther away at each step. They surely were being toyed with...
