Mysti and her cousin have been fucking each other now for several months and what she didn't realize was that her step-brother found out about it and the next time Mysti and her cousin fucked, her step-brother decided to sneak into the bedroom closet and watch the two of them fuck all afternoon. Unfortunately, he was discovered and then slapped by her, but what Mysti DIDN'T know was that her cousin helped her step-brother set the whole thing up because her step-brother wanted to watch his step-sister fuck!
