不小心撞见继妹在洗澡，忍不住想探索她光滑的曲线。

In a moment of unexpected desire, a step brother finds himself alone with his seductive step sister. She, wearing nothing but a lacy bra and thong, bends over to retrieve a book, teasingly revealing her curves. Unable to resist, he approaches her, his hands instinctively gripping her hips. She arches her back, inviting him, as he slides her thong aside and thrusts into her. Their breaths sync as he pumps deeper, her moans echoing. He grips her tighter, matching her building intensity until they both reach a climax, their bodies entwined in raw pleasure.
