Chapter Text
There's some things about the famous bakugou katsuki that no one knew. Bakugou was stressed, this is a well know fact, dealing with post war PTSD was nothing to be looked over, but how he deals with this stress is a different story. That is something that not even his best friend knows about. For bakugou has a kink, a way to relax, an interest with... Piss. So at the end of each day he puts on a pair of trousers, goes into a corner of his room and let's go for a few bless full minutes.
At the end of one particularly stressful day bakugou goes back to his dorm after school and digs through his closet to find the shorts he uses. He stripped off his shirt and sat down at the foot of his bed on the floor.
He closes his eyes ready to let go. He lets out a soft stream only until he feels it penetrate his boxers then stops it. He relishes in the warmth around his cock. The piss quickly cooling he lets out another stream, but as he does a knock sounds in the door. Pissed off he stops the stream and looks down to see a wet spot on his trousers he tries to cover it but before he can another knock sounds. He just need to hope that the person in the other side won't notice.
Bakugou stands up and opens the door. Behind it is kirishima.
"Shitty hair what the fuck do you want?"
"Hi bakubro!! Uh I- what's wrong with your pants?" He questioned looking down. "Uh is that-"
"Spit it out"
"Did you pee yourself?" Kirishima asked blushing furiously.
"Yeah, I was in the damn middle of it before you came in interrupting. Either leave or watch I don't care but I need to piss."
Kirishima was silent for a moment. Bakugou was about to close the door when kiri stopped it with his foot and shuffled inside the room. Bakugou closed the door behind his and went to stand at the foot of his bed again.
Kirishima leaned against the wall watching.
Bakugou closed his eyes trying to relax, but it was so much easier when it was just him. Finally he got a spurt out, then another. A gentle stream started warming his cock and thighs. He paused again and opened his eyes to see kirishima blushing and a tent forming in his pants.
Bakugou let loose a strong stream, this time keeping his eyes open to see kirishimas reaction. While his expression didn't change the tent grew and he reached for his dick.
The liquid flowed in bakugous trousers and boxers until they were fully saturated. The yellow stream snaked down his leg to patter on the floor, making a small puddle bellow him.
Soon his stream ended and bakugou sighed in relief crouching due to his legs shaking to bad to stand. He almost forgot that kirishima was there until he let out a soft groan.
Bakugous dick became erect at the beautiful noise and slipped his hand in his piss soaked trousers to jack himself off. Kirishima followed suit and soon both their pants were soiled with cum.
