You are visiting your friends house and swimming after school when you notice that his big sister (who is a year older than you) has on very small bikini bottoms and you begin staring at her big pussy lip which happens to be hanging out of her bikini. Eventually she sees that you are looking and teases you about it and the erection that it just gave you. She tells you that it is ok and to come inside and she will help you take care of your "problem". Once inside the house she strips out of her bikini and uses a giant red dildo to fuck her pussy hard. She tells you to jerk off so that both of you can have some fun. She wants to see you cum for her and she is going to cum watching you. She destroys her tight pussy with the thick red dildo until she is creamy and cumming. You're next! Your turn to cum!
