I just had one of the best sexual experiences of [m]y li[f]e. | 2016

My girlfriend likes it when i'm "manly". She also likes to brag about me to her friends. Today I got a text that said "Hey, can you come over? I thought of something fun to do." We had been discussing plans, so I thought this was going to be a movie night. When I got to her house, I was surprised to see her and her two friends waiting for me. They took me inside and sat me on the couch next to her friend's boyfriends. Apparently they had come up with some kind of contest, and they explained to me that they wanted to have a foursome with one of us, and the other two guys had already agreed to it. When I asked what the contest was, they giggled and said that I would see. So, I agreed, mildly amused by the whole situation. The contest was then revealed to be one of penis size. Whoever had the biggest dick would get to fuck all the girls. The three girls then got down on their knees in front of their respective man, and took their cock out. I, by only a bit, had the biggest of the three. I heard one of the girls exclaim "Oooh, you weren't lying!" My girlfriend then took my hand and led me to her bedroom, while the other two girls followed suit. When we got to her room, she pushed me onto her bed and ripped my pants off. The other two girls stripped my shirt off and began rubbing me and kissing my neck. My girlfriend did a bit of a strip tease before climbing on to the bed and kissing my dick. The other two stripped down and began kissing each other with my face pressed between their chests while I started to finger them. As my gf stroked and sucked my cock, I played with one girls ass and sucked on the other's nipples, while they rubbed each other and let out loud moans. The two then moved down to my dick and started playing with my balls and fighting over who got to suck my dick while they rubbed and fingered each other. They moved up and one of the girls said she wanted to be first fuck, so she mounted me and started bouncing up and down on my cock. My gf came in and started kissing me passionately while the other girl rode my finger and kissed the other girl. We did this for a while and I spend a little time eating out my gf (from an uncomfortable angle, I might add) before the other girl said it was her turn and she wanted it doggy style. I got off the bed and got behind her and pulled her hair before starting to pound her. She moaned out "ROUGHER!", so I gave it to her. She began eating out the other girl while my girlfriend rubbed her clit and played with her asshole. I was going to cum soon, so I let them know. My gf said she wanted my load for herself, so I pulled out, grabbed her and put her against the wall, before giving her the hardest fuck i've ever given in my life. I had her screaming and scratching my back almost instantly, and the other girls, having little else to do, took turns making out with her and played with my balls. Then, they grabbed her legs and held her up so I would have my hands free to play with them and make them cum one last time. My gf pulled me in for one last kiss before I came more than I've ever cum before. Then we fell asleep in my girlfriend's bed for about an hour. I woke up to a triple blowjob.
