When dad realizes his teen sons are horny all the time and jerk off alot like he did as a boy, he gets them a hooker and rents a motel room. Dad can then watch his sons fuck and get sucked off by the girl or join in with his boys and blow some massive loads of sperm.
Boy #1: Dude, dad got us a hooker again for your birthday this time! Boy #2: Sweet! It's bro bustin time! Dude I got a compliment from the girl last time how good my sperm load tastes. LOL
