We talked about the movie and other movies we had seen. Sarah and I love scary movies, so the movie we were attending was a recent horror film. As the... movie started, I noticed there was barely anyone in the theatre. Two couples were sitting in the front of the theatre with us in the back row and no one else around. Apparently, Sarah had also noticed that we were almost alone in a very dark movie. She reached her hand over and began lightly stroking my dick over my jeans with the devilish smile. Good thing I did because Amy was a young woman on a mission and we three were it. She held the hands of Sean and myself as Dave was now groping her behind and she had no objection.Amy pulled us close and knowing that we would have hardons she began feeling us through our shorts. She was smiling and said looks like daddy and uncle Sean have presents for my birthday! I knew Sean would never have gone for this if he was okay so to speak, he even said Keith if I could stop I would, but I can't just. Innocent chat went on for a few weeks until I was caught by surprise. First he told me that one night he was coming out of the bathroom and Erin had left her bedroom at the same time. Then he told me that within seconds he became aroused and although it wasn't a full erection he had caught Erin looking directly at it. They both froze so it soon became obvious he was getting larger. Nothing was said and they went their separate ways.Later on that evening I was chatting with Erin and purposefully. "You liked it huh?" Wow!"Sully chimed in, "Told you." So you did, so you did." I drained my beer and headed to the fridge for another round. When I returned, Shelly was kneeling between Sully's legs, examining his cock. I was curious myself and saw that head of his cock was like a small apple, with a deep cleft at the bottom of his glans that flared up like a big giant mushroom. She continued to play with it and eventually his precum oozed out and dribbled like honey over her questing finger.
