Your new step-sis sneaks in late, horrified to be caught red handed. She tells you of her wild evening, fucking her hot new boyfriend in the back seat of his car, and you can't help but become aroused. She smiles deviously and asks how many girls you have fucked so far. Your cheeks glow red with embarrassment as you know the figure is a flat zero. She is shocked and amused, at your misfortune, but promises to help you get laid, and wants to have you ready for the events that lay ahead. She wants you to train your cock to last, and if you can last with her JOI, she will hook you up with her hottest friend this weekend at a house party. You quickly drop your pants and grab your cock, eager to learn a trick or two. Who cares that she is your step-sister right? You eagerly rub your cock, in the hopes that you will land a hot fuck this weekend, if you can just prove your worth. You stroke, and enjoy a hot cum countdown, only to be handed a shot glass to cum into. Your mischievous step-sister explains how girls love it when guys shot their own cum, and its a real fucking turn on, so you waste no time at all guzzling it back... The only issue is, it was a test. A one that will decide your virgin fate.
