My girlfriend and I both know that each of us went through a very slutty period in our early 20s before we met where we both had multiple partners and interesting sexual encounters. After meeting, we kind of settled down and had a great monogamous sex life with each for a few years before mutually deciding we both wanted to be a little slutty again. But this time, we'd do it together, so we started fantasizing about the swinger and hotwife lifestyle. We persisted in the fantasy zone of this world for a few years before getting the nerve to make it a reality together.

The first time I watched her with another guy, we were closing out our night in the hotel bar fantasizing about other guys around us like we often did and noticed the guy next to us keep peaking over at her. We assumed he could hear a good bit of what we were talking about and made no attempt to hide it as that was part of the fantasy by then. But nobody had ever approached us. So this time, I leaned over to her and whispered in her ear telling her to go up to the room and put on some sexy lingerie and I'd be up in 15 minutes with the guy sitting next to us. At first, she pretended not to hear what I said and don't think she believed I was actually serious. But after a few more minutes of flirting and finishing her drink, she got up and said "15 minutes. I'll be ready either way" and walked off.

By that point, I had been ready for a while to act on this fantasy. As soon as she was out of view, I turned to the guy next to me (we'll call him John) and asked him how much of the conversation he overheard. Turns out it was enough that I didn't need to fill him on much. I could tell that he was more than ready for an invite and told him I had no idea what he should expect from her, but invited him to up our room for another drink.

As soon as we got to the room, it was clear that another drink wasn't needed. She was laying on the bed in red lingerie, rubbing herself over the lace panties. John followed me over to the bed and we both sat down next to her as I began to rub her legs while she continued to touch herself. Within a minute or so, John started exploring her body with his hands as well while I stripped my clothes off. I climbed back up on the bed naked and brought my cock up to her face, but what happened next is one of the hottest sexual memories I have: She took my cock in her hand, looked up at me and said "I thought you wanted to watch me suck his cock?". I don't remember exactly how I responded, but next thing I knew, she was sitting on the edge of the bed with John in front of her as she was unbuttoning his pants. I watched as she slid his jeans down, exposing his bulging cock through his boxers. I was already rock hard and stroking myself, making sure I didn't make myself cum early, as she took his cock out and teased it a bit before sliding the head of his cock in her mouth. The sound that John made as she took his cock in her mouth might be the second sexiest thing I've ever heard! His cock wasn't that big, but it was so hot watching her hold it as she took it in and out of her mouth, making intermittent eye contact with both of us as she did. She stopped midway through to take her lingerie off and I don't think she ever stopped rubbing her clit the whole time. I leaned in and kissed her as she did and didn't realize how much I'd love tasting another man's cock on her lips. She went right back to sucking his cock, clearly knowing how much it was teasing me and enjoying letting her inner slut out again. I don't think John lasted more than another minute or two before announcing that he was about to cum. She knew that a fantasy of mine was to see another man cum on her and made eye contact as he said this, continuing to suck his cock, but just a little bit slower than before holding him on the edge a bit. I had no idea whether she was going to let him cum in her mouth or pull away and let him cum on her tits. But she was in full on slut mode, knowing we were both loving it, and kept sucking until she felt him start to cum in her mouth. She told me after that she swallowed some of his cum and I could definitely taste it on her when we kissed, but after he started to cum, she took her mouth off of him and stroked out what looked to be still a full load of cum on her tits.

I don't even remember John getting dressed and leaving or how (if) we wiped his cum off her tits. Once she turned back to me, and kissed me letting me taste his cum on her, I fucked her in the most lustful way I ever had discovering how amazing it was to "reclaim" her after another guy got to use her. I think we fucked another 5 or 6 times in the next 24 hours after this encounter and fully discovered that we could definitely both enjoy being slutty together.
