Perhaps the sexiest thing about Sabrina Johnson is the fact that she is entirely unremarkable. Jon Dough fucks her without any regard for her own enjoyment. He knows that he can get another girl at least as good as this one on a few hours notice. When you care about a girl too much it's hard to fuck her as well as you if you didn't care about her at all. Sabrina is easy not to care about and that's what makes her so unfucking believable!
