This all happened 20 years ago, I was about 18. I was going out with a girl who was 24 at the time. I'll call her Jenny.
Jenny was much more experienced than me and one evening Jenny and I were swimming in her pool, doing the usual underwater fondling, when her two roommates joined us in the pool. They were both about her age; Patty was loud and outspoken, while Tammy was more reserved. Anyway we all swam around having fun and drinking beer. Soon Jenny and I went back to our underwater fondling, while the other girls continued to swim.
Jenny had my cock sticking out the leg of my suit and was stroking me gently, when she started pulling my suit down. At first I almost resisted and didn't know what to do. I was just Glad that it was dusk and the pool light was off, so the other girls couldn't see what was happening.
When Jenny had my suit off, she set it on the edge of the pool and the other girls then knew what was up. Before I could do anything, Jenny grabbed my suit, and tossed it over her six foot block wall and swam away from me. She huddled up with Patty and Tammy in the far corner of the pool. I finally swam towards the girls, with the intent to pull Jenny's suit off. But they all climbed out of the pool, grabbing there towels to dry off. At this point I figured the game was over, I was just going to wait for my hard on to go away and grab a towel. Jenny had other plans for me. All three girls tossed there towels into the living room, and Tammy went into the house, only to return with more beer. I figured that now I'd have to make it past them into the living room to grab a towel. I climbed out of the pool and made a mad dash for the door with my hard cock leading the way. I made it to the living room only to find no towel. I heard the girls come in behind me giggling like school girls, and Patty said “ nice ass ." Finally Jenny grabbed me by the hand and led me to the couch, while Patty and Tammy went upstairs. I thought I finally had a break and told Jenny to fetch my shorts, she responded by grabbing my cock, and massaging my balls, just enough to bring me close and having the precum ooz.
Then she let go of me and turned on the TV. This was like 20 years ago, before cable. All she had was this thing called ON TV, which only had one channel. On Saturday nights, which this happened to be, they had soft-core movies, preceded by a show called Arobisize. This was a favorite of mine. It was usually 3 to 6 girls in leotards exercising to music, there suits would always end up exposing quite a bit by the end of the show.
