Girl in the next shower stall
In college I worked at a summer camp that had cabins and shower houses that were all separated - guys in one side of the camp, girls in the other. One of the shower houses had been partitioned so smaller groups in the off season could stay on one side but still have separate men's/women's sides of the shower house. Basically, a little stud and plywood wall was put up in the middle of the building, but the shower stalls were still right next to each other. Between sessions, all the workers stayed on one side in a couple of cabins and used that shower house. One night I was showering late and was in the stall next to the partition wall when I heard the shower next to me turn on. It got me instantly hard thinking about one of the girls I worked with right in the other side of the wall. I called out and asked who was over there, and one of the girls answered. She wasn't anyone I'd particularly had a crush on, but definitely cute and had a great little body. I was so turned on by talking to her through the wall and finally said something like "so, I guess it's kinda weird talking when we're both in the shower huh?" She laughed and said yeah kinda then said something about if I ever thought about the girls being all naked and soapy just a few feet away over there. I said it hasn't really crossed my mind until tonight, but that I sure was thinking about it right now.
By now I was stroking my cock pretty hard, and it got quiet and she just said "so, what are you doing over there?" I got a little embarrassed, but said just relaxing, and she said "ok. I guess I'm just relaxing too" and giggled a little. It was so hot knowing that she was touching herself just a couple of feet away from where I was stroking my dick. I wanted to say more, but was afraid someone might come in because you couldn't always hear the door open and close from in the showers. I was close to finishing and asked if she was still there. She said she was and while she was talking I shot my load all over the wall between us. I guess she could hear me moaning when I did cause she giggled and then turned her water off and said something about me feeling really relaxed now. I just said yeah, a nice shower will do that. She giggled again and said good night, that she was going back to her cabin.
Later that summer, we ended up making out late one night in one of the rec halls. I played with her tits and rubbed her pussy through her shorts, and she sucked my dick a little and gave me a really good handjob, making me cum all over the concrete floor. I had a lot of fun experiences working there, but she was one of the best.
