Saw this post from back in january and nobody filled it but i'm dying for it so here's what it was:
Yurio is a brat and deserves a spanking.
Any of the pairing above, both, a threesome. You choose :)
It's gonna happen. When he's at the onsen going, "you think you can keep him to yourself" and "where's my fucking room, i'm not sharing," and throws a tantrum, Victor rells Yuuri, "Don't worry, I'll sort him right out" and goes after him. Yuuri listens from next door and can tell exactly what's going on; jerks himself off and comes miserably on the floor.
