You were careless leaving your door open while jerking off. Your 'rents could have easily walked in...but LUCKILY it was your horny step-sister. She confesses she's always had a thing for you and proposes a blowjob. It's a risk, but that's part of the fun isn't it? Before you know it, she's on her knees sucking your little penis in her mouth giving you one exhilarating experience of a lifetime! She licks, slurps, and eventually takes your hot load on her tongue and down her throat just before your step-dad comes down the hallway dangerously close to catching you two in this very taboo act!
