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.
