College GF and her Sorority Sister at the Beach

My college GF's aunt had a beach house on the coast about an hour from their house in the city. Every year when school got out, they'd stay there for the week and I would join- relegated to a guest room while her parents were there of course. During the weekend her parents went back to their house in the city and left her and her sister to hang out - kind of a tradition I guess. My GFs younger sister was with a new guy and split almost immediately, leaving us alone for the weekend. On Saturday, she invited over her sorority sister - Ann Marie- who lived close by to hang on the beach with us. To say Ann Marie was stunning is an understatement. A true Southern beauty- dirty blonde, perfect ass, small perky tits- one of those you see on TV when they want to show college girls. I went out to get us beer and when I got back, they were up on the 3rd floor porch since it was too windy at the beach. They both were in very skimpy bikinis and I sat down in a pool chair next to my GF and we started drinking.

Later when I walked back outside, both of them had their tops off. Already having my shirt off I made a joke like - it's about time I was getting self conscious. I sat back down and stared at Ann Marie's tits through my sunglasses. Her small brown nipples were hard as a rock when I first started back down, but then they melted back flat after a while. Then, Ann Marie looked at Jessie my GF and said that it wasn't fair that I got to stare at them shirtless, that I should have to remove my swimsuit bottoms if I were joining them. Egged on I was soon naked in front of them both. I was semi hard but was keeping it under control, when during the middle of their conversation, Jessie reached over and grabbed my cock and started jacking me off slowly. They kept the conversation going like nothing was happening. My head was spinning at first as she slowly stroked my rock hard dick and I was trying not to react. Finally Ann Marie asked what she was doing over there, and my GF said: "take over for me I have to pee". She smiled at me and we went inside- I think because she said she was sweating.

We plopped down on the bed and she went straight to sucking my dick. When Jesse came back into the room, i saw her strip off her bikini bottoms and w/ one knee on the bed started fingering herself, saying something like "thats hot guys, but you should really fuck him". Before I knew it, Ann Marie had climbed on me backwards, and was guiding my rock hard cock into her big messy labias. She slid down my shaft slowly and started moaning while Jessie kissed me. After switching to doggy for a bit, I pushed her away, grabbed Jessie in front of a closet door mirror while Ann Marie watched sweating and breathing heavily. Then we switched again, and I spread my GFs friend legs wide and slowly fucked her. Jessie kept talking dirty to both of us. Then she climbed over the top in between us doggie to me and started making out with her, so I started alternating between fucking my GF doggie, and back to her friend spread open missionary. That probably lasted 45 seconds when I pushed her off and with both their heads side by side I exploded on both of their faces. We all laid naked for an hour laughing and chatting until Ann Marie fell asleep, then Jessie started sucking my dick again as we both stared at AM's naked body. The sex was never mentioned again by any of the 3 of us except by Jessie a few times during sex. She said she never heard AM even reference it one. But it's one of those college experiences you'll never forget!
