Pour Some Sugar On Me (слэш)

Reverse sugar daddy AU - Yuuri wakes up after a night of too much booze and finds himself bombarded with outrageous, expensive gifts that somehow manage to also be extremely thoughtful and match what he likes. At 28, and thinking of himself as ordinary, he thinks that's a bit unusual, creepy even. His roommate Phichit thinks he should roll with it.
Yuuri tries to turn the other man down, he really does, but using erotic pictures of himself to do so somehow doesn't work? To be fair, Phichit told him as much. Before long, there are lots of feelings, and more than a bit of sex, but always in dark rooms, in hotels. At first, Yuuri doesn't care - he's not going there for the decor after all, and the sex is glorious.
Eventually, he realises he wants to get to know the man he knew first as 'V', then as Vitya, but he can't seem to do so. As he grows more desperate, he puts up an ultimatum... and then his whole world shatters.
