First threesome as the Third - Part 1

June 07 2025

While I’d had a few threesomes and moresomes in the past with an ex, this is a story about the first time I was asked to join a couple as their third.

 

Most stories start back and forth messaging over an extended period of time before everyone is comfortable and a suitable time is found to meet everyone's busy schedules. But not this one.

 

It was a Friday, and as I generally work from home I occasionally check the adult dating sites to break up the day, and hopefully stumble across a nice profile or 2.

 

So I had done a search for couples looking for guys, and I then started clicking the next button to quickly view each one of them to see if I may be a match for any of them. After about 10 mins of well used break time I went back to work, but with the dating site still open on a screen next to me. I noticed a message had arrived in my inbox and went to check it out.

 

“Hey mate, noticed you viewed our profile. Any chance you are free tonight to play with me and my partner?”

 

I had no plans, and offers like this don’t often come along out of the blue, but I’m also not one to just say yes without a bit more communication.

 

So I replied letting them know that I was indeed free, and keen if all three of us could do a group chat beforehand. After a bit of back and forward I found out he had been given the task of finding an extra guy for the night and thought I sounded like the right person. He asked for a face pic to share with his partner to see if she approved, and if she did, would then setup a group chat on KIK.

Within minutes of sending the pic a group chat on KIK appeared on my phone. “Hi this is Mary here, Keith just shared your pic. Mmmmmmm” (Names changed to protect to pleasured).

 

Mary exchanged some pics of herself (PG rated) which clearly showed she was a very attractive larger built lady with boobs that obviously needed the attention of 2 guys. It seemed everyone was keen, so they arranged for me to meet them at their apartment at 7:30 that night.

 

I arrived, rang the doorbell and was let into the building and made my way up to their apartment, and knocked on the door. I was welcomed with a warm friendly kiss from Mary and firm handshake and smile from Keith. I had bought with me a bottle of bubbly from my cellar collection and gave it to Mary as I entered their apartment.

 

After some small talk Keith offered me a beer, while Mary excused herself and disappeared to the bathroom. Keith and I sat on the couch and started talking like we were old friends. It was easy and relaxed and we learned about each other's pasts and Mary and Keith’s history together. I didn't think much of Mary heading to the bathroom until I heard the shower start. A little strange to jump in the shower just as a guest arrives, but then again it was a busy Friday so maybe she just ran out of time.

 

Keith started making subtle hints that I should go and see if Mary needed a hand in the shower. They were very subtle and I didn’t pick up on it until we heard the shower stop. I’m not sure if they had both planned for that scenario to happen, or if Keith was just being a bit naughty.

 

Mary eventually reappeared wearing a loose fitting dress that clearly showed plenty of cleavage and the lace around the bra she was sporting underneath. I offered to pour us all some wine. Mary sat at the table while I poured 2 glasses and Keith grabbed himself a beer.

 

As I handed Mary the glass she commented how well a nice shoulder massage would go with the wine. I made a cheeky reply about how she'd be welcome to massage my shoulders, while at the same time moving behind the chair she was sitting on.

 

The shoulder massage didn’t last for long before my hands found their way down the front of her dress and started to massage her very ample breasts. Some how she had mastered a way of encouraging me to move from shoulders to breasts with very little instruction, she just moved her body in ways that guided my hands down, until they were where she wanted them.

 

Mary sat on the chair and enjoyed the attention to her breasts for some time before sliding the top of her dress down and then leaning forward to allow me to remove her bra. As her breasts were now free, I took to one side and started to nibble and suck on her nipples as she let out small sighs of pleasure. Keith took his place on her other breast and we both focused our attention on paying tribute to these amazing breasts.

 

By now I could feel a growing bulge pushing against my jeans. It was one of those uncomfortable bulges you get when your dick is not in a great location to allow for growth, and you can’t really adjust yourself without ruining the moment. Luckily it was at this point that Mary decided that since she was down to just her sexy underwear, Keith and I were overdressed. She stood up from the table, gave each of us a kiss and instructed us to remove our shirts. As we were doing this she commenced rubbing the bulge in my pants, and licking her lips with knowing little glint in her eye. I can’t recall how we got our clothes off, but it happened quickly and Mary was on her knees taking turns sucking mine and Keith's cock. It was very teasing at first, slow licks up and down the shaft and little kisses to the head, and then she would switch cocks. Then she would come back and tease a little further, taking the head our of cock in her mouth and rolling her tongue over the top, before kissing down the shaft and changing cocks again. This build up kept going until she was taking both of us in her mouth at the same time and then deep throating us individually. I was on the edge of exploding everywhere but managed to control myself long enough to suggest Mary move to the couch so she could receive some of what she just gave us.

 

Mary guided me to the couch while Keith went and got himself another beer. Mary sat on the couch, lifted her hips so I could slide her underwear off. She pulled me up to her face to steal a kiss, a kiss which lasted what felt like many minutes. Keith sat at the other end of the couch, as I made my way down her chest, stopping to pay some attention to her breasts before eventually settling in between her wanting lips. I licked her slowly, parting her lips further with every tongue stroke until I could eventually feel her wetness on my tongue.

Her finger tips massaged my scalp as I gently explored her with my tongue. I could feel, and hear her moans as my tongue traced over her clit and then explored her insides. I kept teasing her this way for awhile and then applied some gentle suction to her clit, and at the same time flicked it with my tongue. This sent Mary over the edge, as she came in waves and waves. I held the suction on her clit until she couldn’t take anymore and was trying to squirm out from under my tongue.

 

I came up and gave her a kiss, and the only words she could get out of her mouth was “wow, ohh wow”. Once she gained the ability to speak again, the next words were very clear. “I need to be fucked now”.
