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.
