Performed either during foreplay or sex, Titillatio is when you're titty fucking the woman in question and, assuming her boobs are big enough, she also performs fellatio on you while your penis is between her breasts. A very good time-saving tool for quickies.
Hey baby, i know we're having sex and all but I have to be back at work in ten minutes. Your boobs are pretty big. While you're down there why don't you do a titillatio? That way we can kill two birds with one stone.
