In the throes of addiction, a stepbrother turns to his sister's forbidden body for his next fix. She lies on her stomach, her heart pounding as he kneels behind her, his cock rock hard. He spreads her ass cheeks, running his tongue along her crack, tasting her. She gasps, her body tensing as he pushes his cock into her ass, inch by inch. He fucks her hard, her screams of pleasure-pain filling the room. She claws at the sheets, her orgasm building, as he pounds into her, seeking his own release, their bodies entwined in a dance of desperate, addictive lust.
