The siblings' game of tease and denial escalates, their hearts pounding in sync. She slips off her shorts, revealing her bare, wet pussy, and he can't help but stare. She fingers herself, moaning softly, her eyes locked onto his. He can't take it anymore, his cock throbbing painfully in his pants. He pushes her down onto the couch, spreading her legs, and she gasps as he buries his face in her heat, licking and sucking her clit. She claws at his back, begging him to fuck her, but he wants to make her beg more, to draw out her pleasure, to make her scream his name.
