My Virginity Is A Burden V

Ricky shushes her, declaring: "They're going to get the wrong impression!", as he hears loud knocking on the locked bedroom door. "Exactly. I want them to think I'm losing my virginity", she explains. "They think that you're Mark (her would-be boyfriend from the party). "No, this is a bad idea, sis", he maintains, but she insists: "You owe me, remember?". Liz starts dry humping on top of him, moaning loudly, and Ricky laughs at her attempts to mimic what she's heard in dirty movies. "Well, if you're so experienced, why don't you just show me yourself?", she demands. He reverses their positions, throwing her on her back on the bed, and pretends to hump her, still both fully clothed. The physical contact starts turning both of them on for real, but Ricky doesn't feel right, even pretending -after all, she's his stepsister. Threatening to tell their parents about his throwing the party, she insists they continue, and that he remove his pants. "You're zipper's rubbing on me and it's uncomfortable", she explains. Reluctantly he obliges, revealing a huge boner in his underpants. "Oh wow, that's so big", Liz remarks. He's embarrassed, but she demands: "Just get on top of me again". Their fake sounds of passion turn real as he simulates sex with her, and she suggests: "Do you want to see my tits?". Things accelerate when she shows him, and he naturally covers her nipples with his lips. They continue "pretending" but soon pass the point of no return. Watch the taboo scene unfold...
