The tutor, a strapping young man, arrives to help the sisters with their studies. As the afternoon wears on, the room grows warm, and clothing becomes optional. The teen's curious hands find their way to her tutor's crotch, gently stroking his growing bulge. When her sister walks in, she doesn't bat an eye, instead pulling up a chair to watch, then join in. The room echoes with the sounds of their eager hands, the tutor's moans, and the sisters' shared giggles as they explore their tutor's body, their own desires awakening in the taboo threesome.
