Explodes In Her Hands
Thinking your home alone you decide to jerk off but as soon as your cock gets hard your older step-sister Tara walks in. She criticizes you for masturbating and decides to show you how to do it right. When her hand hits your cock it swells with anticipation and you watch your sisters boobs bounce as she strokes. Her practiced strokes take you over the edge in no time and you explode all over them. As your cum drips off her hand Tara tells you next time the parents are away she's going to teach you how to fuck.
