Last year my bestfriend and his wife came to visit me and my girlfriend. Absolutely nothing noteworthy occurred the first 5 days they were here. But on their last night visiting, we all got super drunk at dinner. Took a cab back to our place and kept on drinking. At some point, not sure how or what led to it, the two girls start making out and talking about an orgy... ...well my friend says "Orgy? Fuck that, either it's a threesome without [my name] or we're just trading you ladies for a few hours." "Trade us?" [his wife] "Yeah, I take [my girlfriends name] and he gets you!" "Are you serious?" [his wife, half angry - half caught off guard] He looks at me and says "What'dya think, you take mine and I take yours?" ...I didn't know what to say. I looked at my girlfriend who, at that moment, looked like she wanted to fuck him, no lie. Kinda pissed me off. So I just said "Cool with me so long as there's rules." "Hell yeah there'll be rules" he says. So I laid them out - "No anal, no choking, no cumming inside the pussy." "Works for me, what about cumming in her mouth" he asks. "If she's willing to do it, but no forcing them to do anything" I stipulate. "Obviously what'd the fuck ya think I'm gonna do." ...At this point the girls have put more distance between the two of them. My best friend reaches out his hand to my girlfriend and she just jumps up, like a fucking whore, and they go off into the guestroom. His wife just sat there in shock and watched them walk off. She's pissed. I immediately thought she was going to either follow them into the guestroom to flip out or to join them instead and I'd be shit out of luck while my girlfriend fucked another dude. ...Instead...she comes back to reality and looks up at me and smiles. She stands up and just walks towards my master bedroom. I follow behind, still unsure if she's up for this. I walk into the bedroom and lock the door. I ask her "do you wanna talk about what's going on, because we don't have to do this." "He's an asshole!" [not yelling, but forcefully spoken] "I want you to do whatever you want to me. No rules. Anal, choke me, fuck it - if you wanna cum inside me go right ahead, you can come in my ass if you want." ...well now I'm fucking surprised as hell. We start making out, taking clothes off, sucking on her tits, grabbing her ass, she's feeling up my cock, unzipping my pants...etc etc. Now we're naked and she's sucking my dick like a pro as I stand against the bed and she's laying down on her side. I lay down and we start 69ing, and her pussy tastes good, like unusually good compared to all the pussy I've ever tasted in my life. All this has been going on for about 10, maybe 15 minutes, that's it...when suddenly there's a knock on the bedroom door. We stop for a second, not sure if we heard the door knock. Then the knock again, and I say "Yeeeeeahh?" "Babe...baby...what are you doing?" [my girlfriend] "What!?!....nothing what are you doing?" "Can I come in?" [my girlfriend] "Why?...where's [my best friends name]?" "Can I just come in and talk to you?" [my girlfriend] "We are talking...what's wrong...just tell me." "He fell asleep." [my girlfriend] "Ok...so go wake him up." "I tried...he's passed out, I think he's really drunk."...[a few seconds of silence]..."all we did was kiss, he couldn't get hard...I mean, he felt me up and stuff, but he couldn't get hard so nothing happened." [my girlfriend] At this point I'm thinking this is awesome, I'm about to let her and we're gonna have a threesome...but just as the second that thought momentarily entered my mind, my best friend's wife jumps off the bed and storms past me to the door. She unlocks the door and [completely naked by the way] opens it up and just gets into my girlfriends face and yells "You're a fucking slut! You've been flirting with my husband all week! Why else do you think he thought this all up, because you've been giving him reason to think he could! You couldn't wait to fuck him, you practically ran into the bedroom with him. Well now you get to see what I go through every night. Karma is a bitch, bitch." She then slams the door to the master bedroom shut and locks the door handle. Grabs the remote to the television on the dresser and puts it on one of those 1000 level channels that's just music. She put it on Hardcore R&B and turned the volume up to like 40. Then she jumped back onto the bed, assumed the doggystyle position and just looks at me and says "what do you think she would've been doing with him right now?" ...I got up behind her, standing on by the bed while she laid face down on it, spit a big glob of saliva onto her asshole, drip spit a hanging glob onto my dick, rubbed it in and then slid it inside her ass. I'll admit, I didn't last long, but I came in her ass. ...We laid down beside each other, talked about what we hated about the other's significant other, and a half hour or so later I went to the master bathroom to piss. She came behind me, turned on the shower and starting washing off. We got it, dried off, and got back into bed. We spent the next couple hours just going down on each other and fucking [not anal though] before finally cumming again and falling asleep. ...Few hours later [now morning] we got up and went into the living room. My girlfriend was sleeping on the couch and her husband was still passed out in the guestroom. She went into the guestroom and shut the door. My girlfriend woke up and just sat on the couch, before finally telling me "Change the sheets on the bed...clean up the bathroom...and don't come back out here until you do." ...So I went and did just that. My best friend and his wife emerged from the guestroom, bags packed and in hand and she looks at us and says [on both of their behalf's I guess] "We've gotta get to the airport so we don't miss our flights. Thanks so much for a great vacation, we'll text you when we get back home." And they just walked out the front door and got in their rental car. No hugs goodbye, no pounds or handshakes, nothing. He didn't say a word, barely looked at me, just sorta stared at the ground... ...My girlfriend took a shower and climbed into the bed. I then took a shower and got into my side of the bed and just laid down facing away from her... ...The entire best part of this whole event -- she puts her hand on my shoulder/back and says "I'm so sorry. Please don't be mad at me. I don't want to lose you, I don't ever want to be without you again."... ...I just said "I'm really tired, I don't want to talk about it." "Do you still love me?" she asked. "Yeah...I love still love you." [We're still together and so are they. We haven't texted, called, seen or heard anything from or about them, other than Facebook, since that day. That was 8 months ago. My girlfriend and I haven't ever spoken about what happened. In some crazy way, I think we're closer because of it. But I know, deep down, she's still a fucking whore.]
