Don't Tell Mum

When you come home and find your stepsister Maya siting on the couch gently teasing her pussy through her panties, she asks you not to tell on her. Then she confesses that she has always wanted to see you jerk off. While giving you some explicit jerk off instructions, she slides her panties to the side and starts rubbing her shaved pussy. The faster you jerk it in front of her, the more turned on she gets, eventually ending up with her panties off, working her shaved pussy while you pump your shaft along with her instructions!
