Mattheo Riddle has a piss kink and it gets him off like nothing else when he restrains people from peeing when they’re desperate to. He’s fingering Story and using magic to literally restrict her from pissing even though she feels as though she’s about to combust. It’s painful how badly she needs to pee. On top of that, he’s fingering her like there’s no tomorrow, and even when she has a crashing orgasm, he keeps the spell going to stop her from relieving herself.
