A brother's cunning plan to seduce his unsuspecting sister unfolds as she innocently enters his room. He's been waiting, his cock throbbing at the thought of her tight, virgin pussy. She's clad in a revealing nightie, her nipples hard from the chill. He offers her a drink, laced with a potent aphrodisiac. As she sips, she feels a wave of heat, her body responding to his closeness. He moves in, his hands roaming her curves, her breath hitching as he pulls her nightie down, revealing her firm tits. She's confused, aroused, but as the drug takes effect, she gives in, moaning as his fingers find her wet slit.
