With his hand slipping beneath the elastic of his boxers, Vincent tries really hard to get inspired.
There was a girl he dated last year who had great boobs that he once got to touch. It was kind of exciting, but she dumped him over something dumb that he can't even remember, so jacking it in her memory is a terrible idea, and the half-naked girl pasted on his wall looks awkward and concave at this angle.
So really, when he's thinking about how stupidly soft and warm Teddy's skin is when his dick is tightening under his fingers, it's only because he has no other option.
Obviously.
