In a quiet music studio, XSany, the teacher's cute step-sister, can't keep her eyes off his bulging crotch. As he lectures, she sneaks her hand under the table, rubbing his growing erection through his pants. He tries to maintain composure, but her expert touch is too much. She frees his throbbing cock, stroking it skillfully until he can't hold back any longer. With a low groan, he cums all over her eager hand, leaving them both breathless and wanting more.
