Me my [boyfriend] and [ex] hangs out for a night
My bf knows I lost my virginity to my ex (when i was 19 and we dated for a year). He gets weirdly obsessed with the details. How big was he. What positions and like how did I cum. It's kinda weird but I didn't mind it after that.
One night he admits he wants to see us together. Says he's been fantasizing about it for months. I think it's a trap but he keeps bringing it up during sex, asking if I miss my ex's dick while he's inside me. I messaged my ex and asked if he's down to meet me somewhere. He immediately replied and told me that he's down and says he always wondered what I was like now that I'm "more experienced." We set it up at a fast food chain to have dinner. But little did he know that my bf is with me while texting him.
That night then, my ex and i had dinner had a little talk. Then I started asking him questions about his sex life. But i don't know I kinda missed him while talking my bf then arrived at the place. I introduced him to my ex and they just sat down making the atmosphere kinda awkward.. and I told him if we go somewhere to have a drink. They agree and we went to a store to buy some drinks. After that I started to feel something intense cause I know something's gonna happen after. The three of us went somewhere dark and like sit in my bf's car at the back of his pick up. I'm not sure how or what are we talking but i just felt a hand in my thigh, and I start slow, kissing, catching up. It was my ex. I pushed him cause I was scared my bf will catch us. My bf is in the side peeing. So i then suddenly asks my bf what should we do. My ex jokingly suggests that we should do a threesome. I laughed and said that we should go home cause its really late. My bf then laughs at his joke but surprisingly wants it too. He suddenly takes off his clothes, and slowly walking towards me. I did not know what to say but i really felt horny and I also go with it, I stand at the back of the car and undress too as if there is no one seeing us. My ex kisses me first and I make eye contact with my bf while my ex slowly fucks me. I Tell him "he's still bigger than you" which makes my bf groan. My bf loves this, and my ex starts fucking me harder, asking if my bf can fuck me like this. I say no. My bf then joins and puts his dick in my mouth and my ex cums on my stomach. My bf rushes over to fuck me immediately after. He came in like a minute, kept saying "you're mine, you're mine" the whole time. I don't know what happen next after we left. It was really intense to the point I just think it was a dream and the next day i think it never happened.
My ex and I don't talk anymore but my bf still asks if I think about him when we're having sex.
