so the other night my g/f's best friend tells us her parents are out of town and that we can come over and spend the night. we get there and hang out for a while when she busts out the wine. we all get pretty sauced and are having a good time. the girls go to change into something more comfortable

and come back looking all kinds of sexy! they are both wearing lacy panties that go half way up their ass and extremely small wife beaters w/o bras. i feel like i'm in heaven now since i have two extremely attractive girls standing in front of me half naked, drunk and one's got her nipples pierced. me and my g/f end up doing it like animals in the kitchen, the living room, the bathroom...but when we weren't busy with that, her best friend was hitting on me like crazy. i broke a glass in her kitchen and she came in there to help me pick it up. her bending over in those little panties turned me on quite a bit! well...my g/f couldn't see us and her friend apparently saw that i was getting a little excited and unexpectedly grabbed me! i was startled at first and then realized her intentions. then she grabbed my hand and put it down her panties where i felt her very moist, cleanly shaven pussy. we started making out with my g/f in the next room and i ended up throwing her up on the counter and taking her clothes off. just as i slipped it in my g/f walks into the kitchen. i think i'm busted! she is not the kind of girl who is down with something like that and i'm not the kind of guy who would do something like that (or so i thought). to my surprise, she walked over, grabbed me rock hard cock, and directed back into her friends soaking vagina. then she starts kissing my neck. WOW!!! now i'm banging this incredibly hot chick on her kitchen counter while another girl of equal attractiveness is kissing my neck and rubbing my balls. we end up having a threesome for an hour and a half and then i fall asleep. the next day we woke up, i had sex with my g/f again and we left. we haven't talked about it since. my g/f has never even like talking about that kind of stuff. she was my first and only, and i was hers, until this weekend. i don't want to bring it up but at the same time i do! now my g/f's parents are leaving all next week and her friend is planning to be spending the majority of the week at her house. will it happen again? or will it just be weird? should i feel bad? i always told myself i would never cheat on a girl no matter what the circumstances. but did i really cheat? i feel bad, but at the same time, it was the most incredible, unexpected thing that has ever happened to me. it seems like i got reality confused with a porno that was never made, but it happened to me! what if her friends boyfriend wants to join in next time? i wouldn't be down with that. what if they want to have a threesome with him and leave me out? there's now way i would allow that! i'm so confused...and happy....and confused...
