In the cramped bathroom, the German step-sis is startled by her brother's entrance. He apologizes, but his eyes linger on her curves. She covers up, but he's already entranced. He approaches, asking if she's ever touched a cock. Hesitant, she agrees to a handjob, her small hand wrapping around his thick shaft. He groans, guiding her until he can't hold back, unleashing a torrent of cum across her shocked, beautiful face.
