stiffy tiffy

From the name Tiffany which is the perfect blonde woman. So beautiful and sexy that being around her is so arousing that men always have a stiffy when they are near her. She not only effects men's porn search history. She causes delays in their day after she leaves because masterbation is almost always a must

I was busy but got nothing done because Stiffy Tiffy said hello. So I fapped the rest of the work day.

stiffles revenge

After you bang your bird you reach under bed for your cum sock. You slip it on your hand like its a sock puppet. When you get ole girls attention you yell "Arrrggghh i gots your booty now take the revenge of Stiffle the Forth" and rub the sock on her mouth as it were kissing.

Bro 1: man Amy was still spitting and complaining of the cuts to her lip from my cum sock.

Bro2: OMG you did not! You let her be attacked by Stiffles Revenge? You heartless prick.
