Small Accidents

Chapter 1

Katsuki knew he didn't have the strongest bladder ever. He always struggled to make it through the day, trying to use the school toilets as little as possible. He didn't want some extra looking at his dick in the urinals and the cubicles were always a fucking mess.

He'd rather piss himself then use those toilets. Well, actually, he wouldn't, but he'd had too many close calls that he sometimes — only in emergencies — would use them.

But today wasn't an emergency. He could make it. Just half an hour left of maths then a 5 minute walk over to the dorms where he could rush upstairs and use the bathrooms in peace.

Katsuki shifted in his seat and crossed his legs tightly. It wasn't suspicious that way, he was just crossing his legs.

It's fine. He could make it.

The lesson droned on for what felt like forever. Maths was never Katsuki's favourite to begin with, but with the growing pressure in his bladder it became almost unbearable.

Katsuki took a deep breath and pressed his legs even harder together. He finished writing out the equation Ectoplasm had put on the bored and dipped a hand below the table to squeeze his dick.

A small dribble of piss leaked out into his underwear, but nothing too alarming. It was just a small bit from him pinching himself.

It's fine.

Under the table, Katsuki's leg bounced nervously. He could feel that small wet patch cooling against his skin like a constant reminder.

Katsuki tried to shift again but as he felt the contents in his bladder splash around and another leak threaten to spill he immediately decided that was a bad idea. He pinched his dick even harder to stop the flow. It hurt, but not as much as the embarrassment he would face if he let go.

He was so full. His stomach was bulging slightly at the bottom and the way his belt dug into his hips definitely wasn't helping.

Katsuki's ears burned as a leak quite a bit bigger than the last seeped out. The wet patch grew larger but thankfully still not enough to show through his trousers. That was good, at least. But one more leak and it would definitely be obvious. He couldn't risk that.

5 more minutes.

Katsuki gripped the pen in his hand and wrote in a robotic manner, fingertips turning white under the force. He answered a question, albeit slower than normal, but he was able to keep his concentration on not wetting himself while also distracting himself.

His dick was half hard in his hand, probably his body trying to stop the oncoming flood. He squeezed it a bit harder.

Now that Katsuki's body had had a taste of relief he couldn't seem to shift the feeling from his mind. His bladder screamed to just let go. In the back of his mind he thought of letting a little bit out to release some of the pressure but he didn't think he'd be able to stop it if he allowed that.

"Sir," someone from near back spoke. Katsuki didn't care enough to see who. "It's four, can we go?"

"Have you finished your questions?" Ectoplasm looked up from the desk.

"No..."

"Then no," he continued marking papers.
