Your cute bratty step-sister accidentally walks in on you while you're getting out of the shower & she's shocked at the puny pecker you've got. I mean, were you taking a cold shower?? She's genuinely fascinated and confused at just how small it really is. She makes fun of you & takes pics to share with her girlfriends while mocking your pathetic jack off attempts with your thumb & forefinger. She genuinely wants to see if that teeny thing works & how it can even cum!!!
