Other than name changes, this is a true story from my life.
I always knew I had an interest in sharing my partner. It started small, encouraging my friends to make sexual jokes around my girlfriend, slapping her ass around them, stuff like that. Jazmine, (My girlfriend) and I often joked about me passing her around. What she'd do if one of my friends made a move on her, or if I encouraged it? It was always light hearted fun that usually ended in us fucking passionately once we were sexually charged enough.
We were now 19, her about 4 months older than I. She always made it easy to roleplay my sexual fantasies as she got a lot of attention from the boys. Jaz was just barely 5'1, dirty blonde with plump, 36DD cup breasts. She had small, pink nipples that loved to poke out when she didn't wear a bra, which she hardly ever did as she knew it drove me wild to see her show them off. She weighed maybe 115lbs, so with tits like hers on such a small frame, she commanded a lot of looks.
I still lived with my parents, who were used to Jaz coming over as we had been together for so long now. One day when she was over, things would finally escalate past roleplaying. My parents weren't home, so Jaz was in my bed wearing only a bra (surprisingly) and her thong. Being 19, we had already fucked once as soon as she got there. We were now just hanging out, talking about what my plans for the rest of the day were. I liked to make music with my buddy Chris, who was coming over to record some vocals soon, as soon as I went to pick him up. Hearing that put some dirty thoughts in her mind.
"Well..." Jaz said as she scooted closer to me, "I am basically naked here. You're really going to bring him over when I'm dressed like this?"
I smirked at her, "don't tempt me"
She laughed and started to rub the growing bulge in my pants, "I know how you talk about me with your friends, I'm sure he wouldn't mind a peak at what you're always bragging about."
I moved her hand underneath my shorts, "I guess we'll see what he walks into. My parents will be home in a few hours, so I should probably go get him."
I removed her hand from my dick, which she had now been stroking for the end of our conversation. I left her on my bed while I went to get Chris. I was about 6 foot flat, white, average body and a 6-7 inch dick, on a good day. Chris was about 6'1, black, toned body and his dick was yet to be seen.
After picking him up, we initially talked about the music we were going to work on. Shortly into the conversation, it turned to Jazmine. Chris was used to me teasing her and didn't mind getting involved in the jokes. One time he even slapped her ass when she walked by. She gave him a dirty look, but I saw her smile when she turned away. That was the first time I fantasized about what else he could do to her.
I told him we were getting it on before I left to pick him up, so I wasn't sure what mood, or clothing, she'd be in when we got back.
He laughed, "so I might finally get to see what you're always talking about!"
I chuckled back, "I guess we'll see what she's in the mood for."
As we pulled into the driveway, my heart, and dick, started pounding. We had always joked about this kind of thing, but was I really going to let another man be involved? At the time, we had lost our virginities to each other and hadn't been with anyone else. The more I thought about it, the less I was thinking with my head and the more I thought with the other one. I was going to do this if she was ready.
We walked inside and up to my bedroom, idly talking about music as our minds were entirely elsewhere. I opened my door to see her exactly how I left her. Laying in her bra and panties, with my blanket just covering her mid section. She knew what she was doing. Chris's jaw hit the floor.
"Hey Jaz, been a while!"
She laughed, "yeah, sorry, we were a little busy earlier and I haven't gotten up yet. Here to make some music?"
Chris continued undressing her with his eyes, "I was, but now my mind's stuck on something else."
She shooed him away and we all laughed before I opened my laptop. We did start working on music, but after a few takes we all quickly realized this wasn't what we were here to do now. After finishing a verse, Chris took off his shirt and laid face down on the bed, next to Jaz, claiming to need a break for a little bit. She was sitting up now. Chris asked if it'd be okay for her to give him a back massage, as he was stressed with the music. She looked at me with a smile, before I gave her permission.
I sat down on the bed behind Jaz as she started rubbing his back. My dick was throbbing as I watched. After a minute or so, I decided to unclasp her bra. She hesitated, but removed it after I pulled it off her shoulders. For the first time, her bare breasts were out for another man. He hadn't even noticed yet as his eyes were closed, enjoying the massage. I gently pushed her back, inching her closer, until eventually her tits pressed into him. He didn't open his eyes, but smiled.
"They feel as big as they always looked"
We all laughed before she mounted him, pressing her chest into his back still. I watched in blissful shock as she started to kiss the nape of his neck and down his shoulders. She was just in her thong now, which she gladly showed off, swaying her hips in the air as she pressed into his back, inviting someone to take her. She looked at me and smiled as she continued to kiss him. She knew what this was doing to me. A few minutes later, she unmounted him and laid on the bed next to me, on her back. Her tits bounced around before Chris finally got up and made eye contact with them.
"Holy shit"
We all laughed again. I moved down so my face was eye level with her tits, before I took the left one into my mouth. Jaz was moaning and gyrating her hips, putting on a show for us. I had stopped paying attention to Chris, until he joined me on the other side. As he started sucking on her right tit, she erupted into a louder moan. Chris and I chuckled at each other as we continued. With my left hand grasping the tit I was sucking, I moved my right hand down her body. I moved her thong out of the way and inched two fingers into her. She was soaking. Her moans got louder as I slid my fingers in and out of her, which was followed by Chris gripping her inner thigh, just out of reach of her pussy.
"You mind if I get a turn?" He asked.
"Go for it" I said as I removed my fingers from her.
