I [M] Left My Girlfriend [F] Alone With My Friend [M] For a Half Hour And When I Came Back, She Was On Her Knees

See my profile for prior DECADES OF PROMISCUOUS PARTNERS true tales. This is Part 6.
Much happened in the year since my girlfriend (at the time) Gina started having threesomes with my friend Jack and I. We had countless interludes which were great but right around the time when Gina and I moved an hour away to the big city, she had started to be put off by Jack’s aggro ways and even made a comment about not liking the musky smell of his balls. He would often throw in put downs when talking to her and she didn’t appreciate it. He and I were still good friends so we’d all hang out, despite her declining attitude toward him.

It had been a couple of months since we’d done anything sexual with Jack, as Gina and I settled into our new apartment. One weekend we decided to have a couple of friends over. My friend John came over and Jack made the trip into the city. We went out for dinner, hit a bar after for a couple of drinks and then back to our apartment to have a last couple of drinks and to smoke some weed. Nothing overtly sexual was going on. Gina was dressed a bit slutty but that was the norm.
After an hour or two, John said he was going to make his way home. I had a few boxes of items from my old apartment which I didn’t need anymore. John wanted to take them and asked if I could help carry them down to his car which was parked a few blocks away. We lived in a top floor walk-up apartment so it was going to take awhile to walk down and out to his car. John and I headed out. I told Gina and Jack I’d be back in a bit. John and I made our way to his car which took about 10 minutes. He was a bit long-winded when he spoke so I ended up standing with him for another 15 minutes while he jibber-jabbered. Finally he was on his way and I took the 10 minute walk back to my place. I wondered if Gina might be aggravated that I left her alone with Jack for a half hour.

I got upstairs and walked into the apartment. I immediately heard Gina’s voice from down the hallway, around the corner in the living room. “Are you alone, Todd” she asked, with obvious concern in her voice. I said yes as I walked down the hallway wondering why she asked. As I round the corner, I see Jack standing there with his pants around his ankles and his fat 7” cock in my hot little girlfriend’s mouth. She laughed with his dick still in her mouth, big eyes looking up at me and he immediately asked in a concerned voice, “she said this is ok, is it?” I was so turned on, my cock almost ripped through my pants as it rose quickly. I told him, “yeah, it’s fine.” I walked right over, undid my pants, pulled out my schlong and put it near her face. She had spit all over her cheeks and chin and seemed slightly out of breath. She wrapped her filthy mouth around my cock and started sucking hard. She is the absolute best at giving head. Jack laughed, looked at me and said, “you just jump right in, don’t you.”

She turned back to his cock and started deep throating him with a lot of passion. At one point, she slid his cock out of her mouth, slid her mouth down the side of his shaft and started licking his balls. She went so deep under, I thought she was licking his ass. I immediately thought about how she said she didn’t like the smell of his balls, that dirty bitch. Jack told me I better hurry up because he was going to cum any second. I know he lasts a long time and I had only been in the apartment for 5 minutes. I wondered how long he was using my girls mouth before I got to the apartment. Right in the middle of me wondering, he started moaning, grabbed a fist full of hair on the top of her head, pushed her head back so her face would take maximum load and unleashed a huge one all over her pretty face. She looked like she was in heaven. He sat down on the sofa, completely out of breath.

Gina turned back toward me and started blowing me with cum all over her face, and I mean all over. I grabbed one side of her hair to move it to the side and I could feel cum touching my forearm. Her hand was covered in his cum as well. With that hand, she grabbed my shaft and started jacking me hard into her mouth. Her mouth and hand were so slippery and warm from the cum, I couldn’t believe it. Feeling that and seeing her in this messy state, I didn’t last long. I erupted all over her face. Jack had a polaroid camera which he used to take a pic of the unbelievable mess. A short while later, Jack left, having gotten what he wanted out of the visit.

After Jack left, I sat and had a drink with Gina and asked her what happened after I left to help John with the boxes. She said a minute or two after I walked out the door, she was sitting on the sofa and Jack was standing, talking to her. She felt turned on by him, stood up and started making out with him. He laughed and asked if it was ok to do this without me there. She told him it’s fine. She told him that he should bend her over, fuck her and cum on her face so that when I walk in, I see her standing there like that. This of course got him going but being the die-hard fan of blow jobs he is, he took off her shirt, sat her down, had her open her mouth and went to work. I remember the next time I saw him, he double-checked if it was ok what happened and finished the conversation with a comment like, “make sure you don’t marry that girl. You should hear the things she says to me when you’re not around.” It was hot to hear she was being so mischievous. Anyway, Gina told me she was really concerned I was going to come back up with John and he would see what she was doing. John probably wouldn’t be surprised because his girlfriend told me a couple of months later that Gina had told her that Jack was fucking her, along with me. I’m a bit shy when it comes to this stuff so I was annoyed Gina had told her that. At the same time, it was a huge turn on that people were starting to hear that I’m with a total slut. Gina and I spent the next few days doing what we always do when she gets dirty with other guys. We fucked like rabbits.

There were more encounters with Jack after that but none worth writing an entire story about. At this point, Gina had now blown or had sex with three other men while in a relationship with me. Her new job in the city was filled with high-powered guys in the financial field. Gina was about to become the office slut. My next story will be about the first time her manager and one of his friends used Gina as their plaything.
