I need your help in the fitting room trying on a little bikini for our family vacation. Once I've changed into it, I notice you're hard for your step-sister's perfect little body. I tell you to start stroking to me if you like it so much, but the catch is that I'm going to have a special surprise for you at the end. I tease you with my ass and tits in my tiny bikini and make you hold your hand out to catch your cum. I've always fantasized about watching you eat your cum for me, so I have you lick up every last drop.
