When you insert you penis and both balls into a womans vagina. Since you cannot thrust in and out you just kind of wiggle around until the woman is about to cum. Just before the woman cums you pull out and shove a rolled-up phone book (yellow pages are preferred) into her vagina as she cums.
Bob bring a phone book over so we can Three Eyed Turtle Ginny later.
