Sorry, Victor, you might have cracked something inside Yuuri open in a way that's helping a lot of what's going on in his brain more than half a dozen years of therapy, but you're still dealing with someone who's balanced on the knife's edge of panic half the time and laughing at him at a point where he's probably the most vulnerable he's ever let himself be in his life (and finally actually seeming like he might be willing to talk dirty) is not your best look.

There's instantly a distressed sort of noise and he's struggling a little-- to get off, away, to hide, suddenly mortified he's been doing any of this at all. Letting him go is the worst possible option, but luckily Victor gets some extra time to react since, insulted or not, Victor's cock right now really is everything in the world he wants and so struggling himself off it isn't just a physical obstacle but a mental one. He actually fails at it the first time because his own body fights him, sends him pushing back again once he gets halfway off, hard enough to see stars.
