I[M] “Cheating” on my Fiancee with our [F]riend.

So I am going to start this off with a little preface on my fiancee and I’s relationship. We both are in our early to mid 20’s and have what we call a “semi open relationship” if that is a thing. Basically means that we can pursue sex with anyone as long as the we both agree on that person. Not just a free for all. Anyway thats important to the story as we keep that to ourselves. For this story I will be F and my fiancee will be M. The friend will be D Anyway storytime…

Cut back a couple of weeks and my fiancee and I were having a couple of friends over for a dinner. We do this every few weeks just for fun. Some friends come over and we like to dress up nice, you know suits and dresses, just for fun and have a nice dinner. Everyone started arriving and a we were all gathered in the kitchen and thats when D walked through the door. She walked in with a skin tight red dress, high heels, and cherry ready lipstick. All underneath her beautiful brunette hair tied up into a clean and tidy bun. She looked gorgeous and I couldn’t help but to stare a little bit as she walked into the kitchen. The dress hugging her tight curves. I was struck by her and my fiancee to notice. Nudging me and looking at me. She knew exactly what I was thinking. She know I found D beautiful.

The night carried on as usual with a few drinks before dinner and then going to the dining room to have dinner. I sat across from D that whole time and I used every opportunity to look at her amazing chest in that dress. Sitting imagining what her perky boobs must look like, but also not staring enough as to let anyone else know I was looking. Until I slipped up. I looked a little to long and D was looking right at me. We made direct eye contact and I just knew she knew exactly what I was looking at. Several more times throughout dinner I had to look. I couldn’t help it she was so beautiful in that dress. And each time she caught me but never said anything or never stopped smiling. Was she letting me look?

Dinner had been over and my fiancee and I began to pick up everyones plates and take them to the kitchen and has we were rinsing off the plates M looked over at me and leaned up to my ear and whispered “I saw you looking at D. I know what your thinking”. My heart raced and I knew there was no point denying it. “Hell yeah I was looking at her! You’ve seen her tonight, shes stunning. Even you want her!”

“I Know I do but I think it would be more fun if you tried to seduce her. You know she’s told me she thinks you are good looking. I bet it would be easy.” And that was it, M just gave me approved of me going after D. From then on it was game on.

The night continued and I was taking every opportunity to flirt with D, and to my surprise she was flirting back! A little unsure of the encounter but she was flirting back! I was complementing her dress and how well it fit her and she seemed to love the attention I was giving her. That’s when I started to notice she was getting more free with her hands, going out of her way to touch me in some way. A slight nudge on my side or moving me out of the way so she could grab something. Several times during these encounters we made eye contact and I could see in her eyes she was thinking the same thing I was. Things go the most interesting when I went to the bathroom and found her coming out. I know this was my chance to make something, anything happen, so I reached over as she walked by and gave her nice ass a firm squeeze. She stopped dead in her tracks turned around, looked at me, smiled, and turned back around and walked to the rest of the party. The rest of the night I just kept thinking about the whole situation. Grabbing her frim butt, her smile, and how she just walked away. I couldn’t get it out of my head. I wanted her bad. The rest of the night we kept up our usual flirting and touching. Nothing to wild as we had others around but still a lot of fun.

Fast forward a few days later and its late evening. M is at work and wont be home for the rest of the night and I was alone. The thought of D’s body in that dress still in my head. I wanted to know what was underneath so bad. So wild idea I decided to send her a message to see if she wanted to come over. Being friends its not uncommon for her to come over to hand out.

F- “Hey D, just and idea you wanna come over an hang out for a b it?” I sent that message and expected no response. I was wrong.
D- “That doesnt sound like a bad idea right now im bored anyway. What are you and M up to?”
F- “Oh M isnt here she is at work tonight”
D- “She wont be mad if we hung out alone?”
F- “Dont worry about her I will hand her lol”
D- “Alright I guess, Ill be over in a little bit”

It was a few minutes later when she showed up and good lord! She showed up in a tight white top that really showed off her awesome rack and a nice pair of yoga pants that hugged her perfect ass. Again I was awestruck, and this time I made no secret of it. “Damn you like amazing” I said to her almost as soon as she walked in.

It was an interesting start to the night. We just talked and watched a couple episodes on Hulu before she got up and walked into the kitchen. This was my chance, something had to happen. I followed her in and walked up behind her, putting my hands on her hips and pushing my dick up against her butt. I was hard. I had been for most of the night from looking at her. She felt it and turned around and looked into my eyes. I leaned down to kiss her soft lips moving my hands up her body to hold D’s amazing tits. They were so soft and her kissing me while I got to touch her tits was unreal. We kept making out and touching each other. occasionally I would move down farther to rub the outside of her panties just to tease.
“What do you wanna do?” I asked her She replied “I wanna go upstairs”

I followed her upstairs looking at her perfect ass. This is it I thought. Im ganna get to fuck her finally. We went into the our bedroom and the first thing I did was spin her around and pull her top and bra off to let those big perky tits out. They were flawless. Her nipples were rock hard and I played with them as continued to make out with her. I could feel her taking off her pants and I assisted her. Then that was it. She was standing there fully naked in front of me. Id thought about this so much and now it finally had happened. I kept making out with her, touching all over her body. Feeling her tight wet pussy and feeling her body tense and move as I slid a finger in. Then I threw her onto the bed and put her on her back spreading her legs. I kissed down her body, kissing each boob and down her stomach, before I got down to her pussy. I started licking that wet little pussy and kissing her clit. Man she was so wet and her pussy tasted so good. I could feel her body moving and she was struggling to keep her legs open. Now im not the best at going down on a girl so maybe she was just really into it. I kept going…really diving into that pussy because I wanted all of it. I wanted every last drop of how we she was. Then she stopped me, looked at me and said “Its my turn”. We switched positions and she pulled off my shorts. She took my hard cock in my hand and kissed the tip once before putting it into her mouth. She was so good at sucking dick. The things she was doing with her mouth was unreal. I couldn’t resist the urge to push down on her head and listen to her let out a few little gags. It felt so good but i wanted more. I stopped her and told her to get on her back. She did and I moved in between her legs.

My dick was so hard and it was covered in her spit. I leaned down, kissed her and place the tip of my dick right on her little pussy. I watched the expressions of her face change as I slowly pushed farther into her. She was so wet and so tight. It was perfection. I kept fucking her a little harder and harder. She was letting out little moans. They got a little louder and louder as I went harder and faster. I looked down and saw her tits bouncing and it just encouraged me to go harder and faster. I was so close. I was about to cum. I didnt know what to do so I told her I was about to cum and she didnt say anything. She just looked at me, smiled and looked down at my dick driving in and out of her pussy. I dont know what that meant but that was it. I came deep inside of D’s pussy. I made sure I pushed as deep as I could inside of her. I dont know why I did that but I did. I had no idea if she was on birth control or not. I pulled my dick out and it was covered in a mixture of my cum and the cream from her pussy. I watched as my load dripped out of her. I looked for a second before I put my dick back inside of her and gave her another few hard deep pumps to make sure my cum got as far in her as it could. again, don’t know why I did that but it was hot.

After all of that we kissed and then she said it. She looked at me and said “Thank you” with a smile. We laid there thinking about what we did and she said she enjoyed it all and that she wanted to do it again sometime. As long as M did find out. Little did she know that M already knew and was ecstatic that we actually did it.

We laid and cuddled for awhile, kissing every once in awhile before she said that she had to leave. I loved to watch her get up and get that amazing body dressed. I couldn’t wait for the next time I would get to use it. The best part was is she was convinced I was cheating and that only made It hotter. She wanted to continue the “affair” and we have and its only gotten hotter and rougher. I tell my fiancée of every encounter and she regularly masturbates listening to the stories. D has sent a bunch of nudes and videos over the weeks and both M and I look at them and fuck to them. Its led to some of the hottest sex of our relationship.

Well that’s my story and its still going on at this time and I still have stories to tell if anyone is interested. Thanks for reading!!!
