In this adult family role-play, a painfully shy stepsister is secretly subjected to daily nipple torment. Though she resisted at first, she soon becomes so sensitive that she cums almost instantly with a filthy orgasm face. Nipple play alone no longer satisfies either of them, so the abuse escalates to penetration. Drooling and dripping wet, she climaxes from only shallow strokes; when he finally pounds her with full force, she erupts into one intense orgasm after another, her entire body trained into an erogenous zone and completely conquered by pleasure.
