A threesome that changed our relationship forever [MFM]

This happened a few months ago and its a pretty long story.

Me (M) and my girlfriend (F) have always been fairly kinky and open. After being together for years, we wanted to change things up a bit and try new things. Long story short, we found another girl to join a threesome and it was pretty great. We were satisfied and went back to our normal sex life. But after a few months my girlfriend suggested we should try a threesome with another guy. I thought it was only fair since we had one with a girl. She said she’d try find someone and I just left it as that.

I noticed the next few weeks, she was on her phone alot more, constantly texting. I figured she was sorting through alot of guys to find the right one. She’s a very pretty girl, she gives off an innocent girl next door vibe so i knew she must be getting alot of attention. I noticed her wearing more revealing clothes and doing her make up more often. She was taking more selfies and texting on her phone alot. I didn’t mind because she looked amazing and seemed to be horny much more often. She was more assertive and seemed alot more confident when we did have sex.

One morning I woke up to her playing with herself while on her phone next to me in bed and I asked her what she was doing. She looked at me with a smirk and told me today was the day for the threesome. I was like oh cool. She must’ve just been excited but I was too sleepy to ask more. When I finally woke up again my partner was getting ready. She shaved, did her make up and put on a very tight dress. I think it was the nerves but I started to get cold feet. I didn’t put much thought into a threesome with another guy before and wasn’t sure how it would play out. But she got on my lap, kissed me and said “I love you so much, but I’m going to fuck this guy with or without you there”. I honestly didn’t know how to reply, She’s never spoken to me like this before. She went back to getting ready and I just sat there speechless but weirdly turned on. I’ve never seen her dominant side before.

The door rang and my partner asked me to answer it. I opened the door and a very tall clean cut guy was standing there. He was probably 10ish years older than us, (we were mid 20s at the time) in nice clothes and looked like he does well for himself. He seemed the opposite of me. Tall, had muscles, dresses in fancy clothing. I awkwardly said “oh hey come in”. He handed me his jacket and said thanks before walking straight into the front room. I offered a drink and he said a beer. Coming back from the kitchen with his beer, my girlfriend was already sitting next to him, giggling and quickly took her arms off him with a smirk when she noticed I came in. She looked so tiny next to him. He pretty much towered over her, and me too. We talked for a bit, getting to know him. Whenever he’d say something my girlfriend would look at me and be like “oh wow honey isn’t that so cool” or something along those lines. He’d make her laugh constantly and she kept touching his arm while saying “you’re so funny”. Seeing her like this was so strange to me. She’s never been like this, it was like I was watching a date. And for some reason, it turned me on a bit and she noticed. She said out loud “aww sweetie are you excited?” And they both laughed. She then looked deeply into my eyes with a smile, turned her head and kissed him. And in seconds they were making out. His hands ran all over her body, then slid up her thigh into her short dress. He started playing with her and she moaned so much. I was in a trance at this point.

She was sat back while he was leaning over, kissing her while he kept rubbing her pussy. After a few minutes he looked at me and said “do you mind taking her panties off?”. I couldn’t really believe what was happening. A man was asking me to take my girlfriend’s panties off. I just kinda did it without thinking. He said thanks bud and slid his fingers inside her. She gasped so loud. “Wow you’re tighter than I thought” he said. She replied “your fingers are so big, keep going”. Then he whispered something in her ear and they both giggled. I literally didn’t know what to do. My girlfriend saw and said “honey come join in”. She asked me to sit next to her and play with myself. I obliged and she called me a good boy. She then got on her knees on the floor and un did his belt, pulling his pants down and then his boxers. Ill never forget her face when she saw his dick. It was like Christmas day for her, her jaw dropped and bit her lip. She held his dick on one hand and mine in the other and giggled. I felt so embarrassed. He was atleast double me in size and girth. He grabbed the back of her head and pushed her down onto his dick. She struggled taking it all but after a few minutes she was giving the best blow job ive ever seen while jerking me off.

After what felt an eternity, he pulled her up and told her to take him to the bedroom. Then told me to help take her dress off and lay her down on the bed. She laid there naked, legs spread and waiting. I didnt know what to do because they wouldn’t even look at me, they were purely fixed on each other. He went up to her and asked her “what do you want”. “I wanna get fucked” she replied. “Be more specific”. “I want you to fuck me right now on this bed”. He climbed ontop of her and I went to get a condom out the drawer, but she said it was fine. “But” and before I could finish the sentence she repeated herself but in a harsher tone. I was shocked because we always use condoms. But before I could think anything else, he started sliding his dick inside her. Ive been the only guy shes ever been with so I was worried with his size, it could hurt her. She asked him to go slow, i could see she was slightly uncomfortable. After a few minutes of gently sliding in, he asked if she was good. She nodded and smiled. He picked up the pace and her eyes rolled back in ecstasy. Seeing a huge muscley tall guy fucking my girlfriend with a huge dick gave me so many emotions. Good and bad ones. But I was so turned on it was hard to think about anything else. He kept asking if she liked it and she’d moan louder. He fucked her so rough, she looked like she was going to break in two. “Oh my god I’m cumming” she screamed. He fucked her harder and harder until she came on his dick. Ive never seen her like that before. Her whole body was shaking and the noises she made were foreign to me.

After a minute he asked me to sit on the edge of the bed. He placed my girlfriend on her knees on the floor and pushed her head onto my dick. I was so happy to finally get some pleasure. But after less than a minute, he pulled her body up so she was bent over sucking my dick with her hands keeping balance on my knees and slid inside her from behind. All I could see was my girlfriend bent over sucking my dick while getting fucked by a huge guy. She was struggling to keep blowing me through her moans, and he eventually grabbed her hair and pulled her head back. She was looking right at me while getting pounded from behind. It was one of the happiest yet messiest I’ve ever seen her. She was getting fucked so hard she struggling maintaining eye contact. After a few minutes he was grunting louder and louder, she moaned “cum for me, cum inside me”. He moaned even more until finally exploding inside her. The smile on her face as it happened was picture perfect.

They both went onto the bed and collapsed into each other’s arms. She asked me to get some water. When i came back they were lightly kissing. I handed them water and couldn’t help but noticed the cum dripping out of her pussy. She noticed too and smirked while saying “its your turn baby”. She opened her legs and told me to come here. I was so blue balled and horny I just did it. I’m not sure what I was thinking but I just needed to cum. I slid inside her and there was no resistance at all. I didnt need to ease in. She was so wet, had cum inside her and was just fucked by a dick twice as big as me. I carried on, and he took her face and started making out with her. I think i lasted about 30 seconds before I came. It was the most ground breaking cum I’ve ever had. I’ve never cummed that much in my life. She barely even noticed, she was so fixed on making out with him. I dropped on the bed next to her and just laid there in pure pleasure, trying not to think about what just happened.

I’ll rush what happened next. He put his clothes on, they kissed some more, he left and said “text me”. Me and my girlfriend laid in bed in each other’s arms not saying a word for what felt like hours. Ever since that night, things between us has changed. Shes much more assertive with me, taken a more dominant role in daily life and especially the bed room. She texts him alot, send pictures and sometimes video chats. She likes to turn me on by talking about him, what they do, she shows me their texts. I’m screwed because it turns me on so much that I don’t want it to stop. They have a date planned once quaratine is over to get dinner and drinks together. She jokes about how she has two boyfriends now.

The relationship dynamic has completely changed and I dont think it’s going to go back to “normal” but for now, we’re both pretty happy and excited with what’s to come. I’m sure alot of people won’t understand as it’s not for everyone, but it somehow works and we’re closer than ever before.
