Did you have fun with your friends?”“I did. It wasn’t nearly as much fun as we had this afternoon at the Rap Session, but I enjoy hanging out wi...h them. Most of them are either finishing their degrees or are professors, though there is one guy who’s a chemical engineer.”“What do you guys do?”“Drink coffee, tea, soda, or beer, and talk and listen to music. We ordered pizza for dinner. At least we don’t have to study at this point. Well, most of us don’t. We also occasionally get together for. “Oh no, please don’t stop” I ignored her for the moment then decided to do something I’ve always wanted to try. With Sarah on her back, I pulled her stocking clad legs up and bent her back to the point where her knees were around her ears. I then slid my prick under the top of her stocking. Sarah must have sensed my intention and placed her hands on the gap of her nylons, trapping my cock between her nylon and bare thigh. Exactly what I wanted. I began to pump slowly, feeling the raspy,. As she started to undo her jeans she looked up at me. "Aren't you going to undress?" Janice said. "I thought I'd just watch you first," I answered. I was surprised the mind control was working so well, I was about to have my fantasy of fucking her up the arse and she really wanted it from me. I let out a laugh as I pulled my shirt over my head. As I started to undo my pants, my eyes wandered back to Janice, who was sliding hers jeans down her legs, she was so overweight but it did not matter to. My sister’s unclothed body, the poses she took and what they were doing were like doses of steroids to my libido. I was determined, if he could do it, I could do it. I didn’t find any clue that he had been sharing the pictures of Dee with anyone or on social media so her secret was just between them and me. But that could change. I waited until Dee could look at me again without burning red and swearing; about three days. When she stopped leaving a room when I came in I decided it was time.
