Preface:
So I have a girlfriend (we'll call her Kenzie). Me and her have always been very, very sexual people. We're very leniant with each other when it comes to sexual freedoms. We even allow each other to fuck other people, but only if the other is informed of it and is okay with the person. We do still love sex with each other a lot as well too, but the thrill of sex with other people to both of us is also quite awesome. Both of us are pansexual so we can be sexually attracted to any sex or gender. Basically I'm a man-whore and she's a slut, but we're both proud and okay with that. (We're both STD free as well.) For a while we'd wanted to have an orgy, a gang bang, or some harem sex. Finally, after around year of wanting one of those to happen and trying to make one happen, one finally happened. The following is the story of that.
The Story Itself:
So one day in mid-March, Kenzie and I were hanging out with some of my friends and joking around and having fun. (We'll refer to my friends as Connor, Brad, Casey, and Jack.) We were at a park with no one else around because it was around 11 AM. It was a warm day between like 15Β° to 20Β° C. We were walking around the park talking about random things and making tons of sexual jokes. Keep in mind that all of my friends were also rather sexual as well. While we were walking around Kenzie excused herself because she had to go to the bathroom and pee. Kenzie has a great butt, so all of us stared at it as she walked away towards the bathroom. She was wearing black leggings as well that were a bit sheer when she sat down or bent over, letting people see her thong if she did either of those. While she was there my friends began to talk a bit sexually about her.
Connor said first "Damn dude, Kenzie's got one great ass. You one lucky guy."
Casey followed that up by saying "If Kenzie was my girl I'd go to town on that ass every night."
I responded by saying "I do quite a lot. She loves takin' it up the butt."
Brad then said "She's an anal lover too, niiiiice."
Since I knew how sexual Kenzie was, I mean we'd been dating for quite a long time now, I told the guys if they wanted to grab her butt and smack her ass they all could. In fact I told them they should. They were slightly shocked at first so of course I had to explain a bit of our sexual leniance and love for sex to them all. After that I told them that she'd enjoy them smacking her butt, because I knew she loved when people touched and smacked her butt. After around 5 to 7 minutes Kenzie came back. She was smiling at all of us as she walked back from the bathroom. She had an incredible smile.
She then said to us "So what have you boys been up to while I was gone?"
None of us said a thing about what we'd just talked about so we shrugged it off and said we didn't do much. We then resumed the conversation we were having before she went to the bathroom and began walking again. About 10 or so minutes into us walking around Casey came up behind her and slipped his hand onto her ass and squeezed it a bit. She let out a tiny squeek when he did this due to her not being prepared for it. Then she smirked, looked towards me, then looked back at Casey.
When she looked at him, she still had that smirk on her face, and then said "Enjoying yourself there?"
Casey smiled in a somewhat creepy looking manor and said "Oh yes I am, this thing is great."
Soon after that we stopped walking and stood in one spot. It didn't take long before the other three came up and started grabbing her, two of them each grabbed a cheek of her ass, and the third decided that he'd grab her nice 32Cs. Kenzie couldn't help it so she put her face against me and let out a slight moan. Only I heard her moan though because it was a bit quiet. I then joined in and squeezed her tits. Soon enough, we started to see other people coming to the park. So then we had to stop groping her like that. So we shrugged the experience off and began walking around like we were until noon when my friends left and so did me and Kenzie.
We drove back to my house.
When we got there, went inside and got our shoes and stuff off Kenzie asked me "So, did you tell them about my sluttiness boo?"
