Summer Brooks is a naughty stepsister. One night, she heard some noise coming from her stepbrothers bedroom and she went to investigate. She found her brother fucking his girlfriend hard and making her moan. She knew she shouldnt watch but she couldnt help herself, so she hid in the doorway and started rubbing herself through her panties.Shes so turned on watching him fuck that she sneaks off and hides in the bathroom where she can play with herself in peace. That comes to a head when her stepbrother walks in and catches her. She tells him that she was watching him fuck and it really turned her on. I saw you watching me he admits, wrapping his towel around his waist and sitting on the counter in front of her. Her eyes fix on his crotch, hoping to catch a glimpse of his cock. Can you go again? she asks. He shows her exactly how much more he can go, fucking his stepsisters mouth before taking her from behind. They make their way back to her bedroom and he fucks her hard, making sure his girlfriend sitting in the other room, doesnt catch them.
