Kamoshida fucks Rin so hard that she pisses herself.

Rin had been eager to bend over the desk in the first place, because although she knew that having sex with a teacher was wrong, there was something about Kamoshida that she felt drawn to. The rumours about him were apparently true, but that didn't bother her, if only because she hadn't really thought about them. She was an innocent, wide-eyed teenage girl with the ideal man in her mind, and although Kamoshida was very far from that ideal man, he knew how to pretend that he was a lot closer to it.

She had been eager to bend over the desk, but the way that his hands clamped down around her wrists, holding her to it after the fact, were emblematic of a lot more than just his physical strength. Rin had no way of escaping, and honestly? With his cock inside her, hammering away at her cervix with each hard thrust that he gave, escape was a hard thing for her to consider very seriously. It was nothing like she had imagined it to be. She had read in books about intense sexual encounters and the way that they completely overtook someone's body, and although she'd had sexual experiences before, this was nothing like any of those, and more closely resembled those in the books.

Intense, overwhelming and most of all deeply exciting, sending shivers throughout her body that only seemed to reverberate into more shivers rather than dying out after they had caused her muscles to spasm or a moan to slip free from her mouth. As a result, each moan that she gave was shaky and needy, and for how long her eyes had been rolled into the back of her head she hadn't actually been able to see straight for at least a solid minute or so.

That was when it happened. It was all too much, her body couldn't handle it, and if the desk hadn't been supporting her than she would have almost certainly collapsed to the ground entirely. Her bladder relaxed, and piss began to sprinkle out from her, before turning into a solid stream, then a gush as she accepted what was happening and stopped trying to fight it. A muttered apology left her, but Kamoshida only fucked her harder, even as the piss formed a puddle on the ground large enough to eclipse both pairs of shoes.
