This story is completely true, and it's an account of the beginning of the hottest sexual encounters of my life.

This all took place several years ago. My girlfriend [F50] (ages in 2017) and I [M45] have been together for over a decade, but from the earliest stage of our relationship we found that we both had a penchant for MMF threesomes. I had experienced a few before, plus some one-on-one with a few different men.

At the time we met, we were both separated but still married. We had both fairly recently come out of unhappy marriages. I had been out of my marriage for a few years, so I had had time to experiment and make up for lost time in terms of sexual experimentation.

We didn't have sex on our first date, but we both wanted to. But during our date the sparks were evident, and Cleo had mentioned that she'd always wanted to have sex with two men at the same time. I enthusiastically told her that we could definitely make that happen!

So, for a few years we merely fantasized. I'd come up with different scenarios and we'd have hot sex while fantasizing. We had sex an average of three times a day back then.

Sometime around 2016, we finally found a guy that seemed like a good candidate. This was on Craigslist back when the personals were still in existence. (Sure do miss those days.) Dave was a few years younger than me. He worked in the food service industry, was divorced and had a couple of teenage children. He worked a lot and we had trouble coordinating a meet-up. He wasn't great at sexting, and didn't have a lot of pictures to share. But the few that we did see showed that he had an impressive cock.

I have a penchant for photography as a hobby, and I had a library of sexy pics of my girlfriend. Never including her face, but some very hot explicit lingerie-clad photos of her with toys, her skin glowing and shiny with oil. She has gorgeous natural big round breasts with beautiful, suckable nipples.

I sent Dave a few of my favorites and asked if he could take a picture of himself cumming on her photos. (I hadn't heard the term "cum tribute" at that time.) Wow, did he deliver! I got back a picture that he had taken of his big hard cock in one hand, positioned over an iPad. On the screen of the iPad was a picture of my girlfriend in fishnet stockings, a close-up of her gorgeous smooth pussy, legs spread, with the head of her Hitachi massager on her clit. There was a large puddle of cum on the screen of the iPad, all over her open pussy lips. It's one of the hottest photos I've ever seen, and I still masturbate to it all these years later.

Eventually we met up in person at a bar near our house. Cleo wore a sexy tight shirt with a little zipper at the neck. As we were walking in, we saw Dave stroll in just ahead of time. I whispered, "That's him!" to Cleo. "Really?!", she said. She seemed pleasantly surprised.

Inside the bar, I walked up to him and introduced myself. He was friendly and affable, with an easy, deep chuckle. He was about six feet tall, heavy-set, but clearly muscular. We sat at a table in the back and chatted about various things. Cleo is very social and kept the conversation going. It seemed like there was very good chemistry between the three of us. From our chats online, I knew that he basically identified as straight, but not completely. I guess it would be termed "heteroflexible" nowadays.

After loosening up with a drink or two, things got a little more flirtatious. While Cleo and Dave were talking, I reached over and slid down the zipper on Cleo's shirt, revealing her abundant cleavage. Dave liked that. He kind of smirked and reached down to subtly adjust himself.

So, we didn't have sex that night. Nor did we on another occasion where we met for drinks and appetizers at a Mexican restaurant. I found out after that time that he was rubbing her leg under the table, and I was completely oblivious. I loved it when she eventually told me about that. I have a real kink for secret/cheating partners. I loved that they were doing something in secret with me right there. More of that later.

We finally set a firm date to get together. We booked a hotel suite in the same town where he lived, and we went to have dinner and drinks at the restaurant where he worked. While we were there he came over and greeted us cordially as if we were old friends. He was busy, so he would only stop by every little bit until he was finally able to drag himself away. We had taken an Uber to the restaurant, so we all piled into his Mini Cooper for the drive over to the hotel.

Once at the hotel, we all went in and sat down in the living room. Cleo and I on the couch, Dave on a chair. I announced that I was going to take a shower and freshen up. I wanted to leave them alone together.

I came back out ten or fifteen minutes later, wrapped only in a towel. Cleo and Dave were still sitting in their respective spots where I left them, Dave sipping a bottle of beer, Cleo with a plastic hotel cup that contained some wine. Dave said that he was going to take a shower, and Cleo and I moved to the bedroom. She changed out of her street clothes and put on some sexy thigh-high stockings and a lacy lingerie top and black lace panties. She and I started making out and petting each other. I took off my towel and kneeled on the bed between her legs.

A few minutes later Dave emerged from the shower with a towel wrapped around his waist. He was a big guy with a big belly, thick strong legs and powerful arms. He sported a reddish beard and close-cropped reddish hair. He kneeled on the bed to Cleo's right, and I was between her legs caressing the insides of her thighs. As Dave kneeled next to her, he let his towel drop and his fully-erect cock sprang into view. It was big. And thick. If knew that he would be, but it's kind of hard to really judge size from photos. There it was. Wow. Cleo reached for it immediately and wrapped her hands around it. Very quickly it was in her mouth while I knelt between her legs and watched, rubbing her soaked pussy through her panties. My mouth was watering. "Can I get in on this too?" I asked. They both agreed, and a few seconds later it was in my mouth. I savored the feel of it, running my tongue over the large head. Cleo and I licked and sucked on it together. It was clear that we both enjoyed his cock.

The three of us got down to business. The next memories are a bit hazy. Our hands were all over Cleo. We took turns going down on her and slipping our fingers inside her. She was as wet as I've ever seen her, just dripping. She sucked and stroked us both and we had her moaning and panting loudly as we worked her up more and more. Eventually she couldn't take it anymore. "Someone needs to fuck me, and I don't care who." My heart leaped. This was it! It was finally going to happen. I reached for the box of condoms that I had brought. I took out one foil package and handed it to Dave. I watched as he opened it, took it out of the package, and rolled it onto his throbbing shaft. It was unbelievably tight on his cock, highlighting every vein and contour. It dawned on me that I should have brought magnum condoms, but, well, here we go!

I watched in awe as Dave positioned himself in a kneeling position between Cleo's spread legs. I watched as his cock just disappeared inside her. There it was. I was watching another man actually fuck my girlfriend. I was entranced watching them together. He slid in and out like a slow, well-oiled machine. Cleo moaned breathily and rolled her hips to meet his gentle thrusts. I loved the expressions on their faces. They were both clearly loving it. I continued to caress and suck her breasts and erect nipples while Dave increased his speed. The chemistry between them was amazing. I watched them fuck in missionary position for several minutes while Cleo sucked my cock and moaned. After a bit, Dave suggested that we switch. We spent the next 45 minutes in various positions and combinations. It was just amazing to not only watch, but to be a part of the whole thing.

At one point, Dave was on top of her in missionary again and pounding her energetically. Cleo was in heaven. Suddenly, Dave stopped and pulled out. I saw the big head of his cock, exposed to the air and shiny with Cleo's juices, the remnants of the broken condom bunched up around the lower part of his hard shaft. Dave grimaced and pulled off the broken condom and laid down across the bed, his cock showing no signs of softening.

Cleo got on her hands and knees and grabbed his cock, stroking and sucking it in earnest. I got behind her and slid into her pussy from behind and watched. Dave was close to finishing, his cock huge and reddish-pink. It was so incredible and hot to watch Cleo eagerly pleasuring a big hard, cock. Stroking it and sucking it as Dave shuddered and let out low moans and breaths. Suddenly Dave let out a groan and thick gobs of cum started spurting into the air. I held Cleo's hips and fucked her slowly and deeply from behind. She was transfixed, pumping his dick with her fist as he kept shooting straight into the air. I saw a big gob of thick, milky semen land on her forearm and that was it for me. I pulled her hips hard against me and shot my own load deep inside her. Dave was breathing hard, laying there, his cock still hard, Cleo still stroking it gently. He said, "I'm still cumming!" in surprise as she milked out the last few drops. We all collapsed on the bed in a heap. I lay there gently caressing Cleo as Dave went to the bathroom to freshen up. By the time he got back, I was hard again and was cross-legged with Cleo, on top of her fucking her again. Dave walked up, fully dressed and told us that he had to go. We said our goodbyes, continuing to fuck as he left and shut the hotel room behind him.

It was a truly amazing experience, and we had a few more with Dave until he eventually moved away. I've been trying ever since to get something like that to happen again, but no luck so far. Hopefully someday, as it was truly amazing to have someone like that in our lives that we could explore with.
