Where do I start? There was the time where I had a bunch of people come to my house for a pool party sort of thing. I was serving up drinks to people and walked over to two girls who were sharing a deck chair. I knew them both and had hooked up with one of then before. As I handed one of them a drink the other undid the drawstring of my board shorts and pulled out my cock and started playing with it. The other took a sip of her drink and told her friend to put it in her mouth. From there they took turns sucking it. They eventually noticed a few people were present and so they stopped. About an hour later one one of them had been put to bed because she had drank waaaaaaaay too much. I every 30 mins or so I kept checking on her because she was sleeping in my bed and I didn't want her to spew. Whilst checking on her she started talking to me, she had sobered up. Her red headed friend came up behind me and pushed me on the bed and then closed the door. The 2 of them then continued doing what they had started before. The red head was getting a bit greedy and the blonde kept telling her it was her turn, so to settle the argument I put my hand down the blonde's pants and started playing with her. This went on for quite some time. The blonde had taken her top off and had her tits in my face whilst I continued diddling. The red head by that time had lifted her skirt, removed her swimwear and then say firmly on my dick. She started riding it when all of a sudden my friend Brad busted in. I didn't know brad liked the red head and there she was -blam!-ing me. As you could imagine he cracked the shits, the girls got a surprise and everything stopped. There was also the time my ex girlfriend was over with 2 if her friends in the pool. I was inside playing the xbox in my room whilst they talked girl stuff. Eventually my ex came in and jumped on my back piggy back style and started kissing/sucking/licking my neck and ears. She knew it was my weak spot and she then started undoing my pants and then started jerking me off from behind. As she did that her chubby-ish, big titted friend walked in and started laughing. She then said if we are going to keep going then she wants in on it. I couldn't care less as my dick was firmly in my ex's grasp. My ex then agreed with her friend on the grounds that only she gets to make me cum. Her friend took off her pants and lifted her shirt just enough so her tits were out. She then got on all 4's and I -blam!-ed her from behind whilst my ex played with my balls with one hand and played with her friend's clit with the other. Her friend came pretty quick but I didn't want to stop. Unfortunately my ex removed her pants and then told us to do the same to her. And we did. However this time I got to cum too. The feeling of being inside her and having my balls grasped/played with at the same time was fantastic. I do have other stories, like the time I had sex with 3 different girls in one day, and a few other random encounters with friends/strangers. However these two accounts are my only threesome encounters.
