Watching Mandy Masturbate – Then Offering to Help

... herself, and what’s worse, she could already picture his big, awkward fingers on her delicate pussy. “I have to turn this into a positive...SOMEHOW” said Mandy, as she tried to picture her brother’s fingers on her pussy, but with him wearing a mask in the likeness of one of the handsome football players that she really wished would have their way with her. It was a deal. The following day, when Jim and Mandy got home, they would both head upstairs to Mandy’s room, where Jim would watch, and then participate in Mandy’s routine. She cringed as he watched her take off her sweatshirt and her pretty pink leotard. She couldn’t believe her loser of a brother was staring at her beautiful naked body.

Sure, a deal was a deal, and their parents would never find out about Mandy’s masturbating habit, but she couldn’t keep it a secret that she couldn’t wait to have her brother’s magic fingers on her pussy again. And so it was. The following day, both kids would be staying late at school again, but it would only be 2 days before they had a few hours alone at home. Mandy promised Jim that she would wear another one of the sexy leotards that showed off her beautiful body, and made him as excited as a 5-year old on Christmas, and in return, Jim promised to work his magic fingers, and give Mandy an orgasm ten times more powerful than she had just experienced.
