Cheated on my BF with my friends BF [MF]

I still can’t believe this happened and I’m still turned on just reliving the moment and writing about it. This happened this past weekend, I’ll give some back story before we dive right in. My boyfriend and I have been together for 2 years. He’s a very fit guy, was a running back in high school and has still kept that physique. We both stand at around 5’11”. I lost my virginity to him, we gave sex very often. He’s good with his mouth and has a 4.5 inch dick that I’ve always been satisfied with. We were staying at my friends boyfriends house for the weekend, my friend was a pretty tall girl her self at around 5’9” and she is very pretty. Her boyfriend who she’s been with for about 3 months ago is a short skinny guy standing around 5’5”, and to be honest he’s kinda nerdy but he seemed very nice whenever I talked to him.

[MF] I can’t stop thinking of him

In my free time I do modeling, it’s my favorite hobby and I absolutely love to do it. We have a group that does shoots together for our main photographer it’s 5 of us 3 girls and 2 guys. We do a lot of swimsuit shoots and just shoots in normal clothing, typical modeling stuff. There has always been some sexual tension between some of the girls and guys, but I was never apart of this as I have a boyfriend. Then another guy was added into our group. My first sight of him was in his normal attire of jeans and a t shirt, from first sight I could tell he was in extremely good shape and had an amazing body. He wasn’t very tall at all, he is actually shorter than me. He was standing around 5’5”. We have curtains we change behind on set, apparently he didn’t get the memo because he started stripping down right on set. He had such nice dark chocolate skin, ripped abs and really nice arms. That wasn’t the best part though, he pulled his boxers down and I was absolutely shell shocked. I’m a believer that size doesn’t matter but my gosh was this guy hung like a horse and it was definitely nice to look at even when soft, it was an absolute hammer. Apparently he was extremely comfortable walking around naked as he didn’t care the slightest when he caught me staring, I was in heaven. Unfortunately one of the other guys told him we change behind curtains on set, and so he went behind the curtain to change. I haven’t been able to get him out of my head since, I’ve even been thinking of him while having sex with my boyfriend. Feel free to pm me, feedback is appreciated this is my first story
