The camera focused on the living room security camera. The busty older sister wore a sheer white slip dress, nothing underneath, her full breasts trembling slightly with her breath. Her younger brother, clutching a bottle of aphrodisiacs, grinned wickedly and whispered in her ear, "Sis, we agreed on once an hour, don't even think about escaping." The sister bit her lip, her eyes glazed, her legs involuntarily clamping together. The drug took effect; she felt hot all over, her nipples hardening and erect beneath the fabric. The brother ripped off her bra strap, her breasts bouncing out. He lowered his head and sucked on her pink nipples, causing her to throw her head back and let out a suppressed moan. He pressed her onto the sofa, his thick penis aimed at her wet vagina, and thrust it in all the way. The sister screamed and arched her back, her juices flowing down her thighs. He thrust wildly, each stroke reaching the deepest point, his penis frothing as it went in and out, the sounds of his thrusts mingling with her moans. Her brother gripped her waist, flipped her over, and thrust into her from behind. Her large breasts swayed violently with each impact, and her buttocks were bruised and red. She turned and begged for mercy, but only received more intense thrusting in return, until a surge of heat filled her womb, her body convulsed, and she climaxed wantonly.
