Was Not Expecting This

Reading the stories here make me so horny. I especially love the ones women submit. The various stories made me remember an incident that happened to me when I was a sophomore in high school. I went over to my friend Kyle's house to hang out one day. We were playing video games or something and then he had to go help his step dad do something and said he'd be back after while. His sister was there with her friend and she was two years younger than me, her friend was the same age. They were always checking me out making comments about seeing my dick and stuff. I always played it off since Kyle was around or close by but it always turned me on. I knew this time that they would start in like they always did and that there would be a perfect opportunity to show them my cock. I didn't expect anything to happen though. I figured I'd show them it, then that would be it, they'd probably masturbate to the incident behind closed doors and I'd probably do the same. Well they started in and I didn't do anything for a little while and then went to Kyle's room and laid on the bed. They came in and began to grab my dick through my shorts like they had in the past. Melissa began to pull my shorts down a little then stopped, figuring I wouldn't let her do it but she liked the idea of teasing. I helped out, pulling down my shorts the rest of the way, exposing my stiff, rock hard cock. They both said Oh my God, at first reluctant to grab and touch it. They soon got courageous and started to grope and grab it, then started taking turns stroking it. I egged it on by moaning and cocking my head back and closing my eyes with each stroke. Soon it was full blown stroking, at first each one at a time then both trying get their hand under the other's for a spot. This was too much for me to take. After a few minutes of them stroking me I grunted and shot cum high in the air, it landing on my stomach. They laughed and had a good time and so did I. We agreed that we'd do it again, but it never did happen.
