F43 unplanned houseboat threesome

First off, yes I know this is terrible. Secondly, I’m fully aware my brain doesn’t make sense when it comes to the threesome thing.

A little backstory first. When my bf and I first met after our divorces, we were exploring our sex life and talking about kinks etc. He told me he had always wanted a threesome and I told him that I was open to it(with another woman, I’ve never had much of a desire with 2 men ). I also have a friend that I knew would be into it(though I’ve never told him that). After I fell in love with him and we became more serious, I completely changed my mind. I can’t stand the thought of him with another woman. At some point threesomes came up again and I told him this. He was bummed because I had gotten his hopes up some, but didn’t push the issue too much.

Fast forward and even been together a few years now. We went on vacation a few weeks ago and rented a docked houseboat. The vacation was pretty much sit out in the sun, drink all day, swim, etc.. It was amazing and 3 days in we met another houseboat with 3 couples on it who were doing the same thing. Ended up hanging out with them most of the trip.

On the 2nd to last night of the trip we were all sitting on the back patio area of their houseboat drinking and playing games and what not. My boyfriend drank waaaay too much and ended up getting sick and passing out. I managed to get him back to our houseboat and in bed, then went back out and continued games and drinking with everyone else.

Eventually, it dwindled down to just two couples and myself. Not long after a lot of the conversation turned sexual, and I learned that the two couples were swingers and sometimes with each other. My curiosity got the best of me and I just asked a couple questions(how they avoid jealousy etc). The sexuality of the conversation continued to progress and I could tell everyone was getting worked up. Eventually, the topic was approached of everyone playing a little truth or dare and they wanted me to join as well. It sounded super hot(I probably haven’t played truth or dare for 25+ years), but I was also uncomfortable without my boyfriend being out there. They invited me to just watch if I wanted to because they enjoy that, and I thought there was no harm in that.

It started out very simple, so much so that I was surprised based on that these couples had had sex with each other that they enjoyed it being this simple. Flashing out to the water( it was dark out so it wasn’t that risqué) , lap dances, walking up the dock Into the more public area topless, etc. It was a lot of fun and I enjoyed watching them. Eventually, one of the girls did dare me to flash my tits out to the water. I told her no, but kind of did want to do it because I figured at least I’m not completely flashing my tits to somebody, and I think she could tell because she ended up convincing me to do it. We walked out to the end of the dock and flashed, and while my tits were out, she reached over and pinched one of my nipples and complimented my tits. It turned me on like crazy.

The night got a lot more physical from there, with everyone(but me) starting to perform sex acts on each other. Eventually, the same girl that pinched my nipple came over and started giving me a lap dance “jokingly”. I actually enjoyed it quite a bit and feel myself getting more wet as she danced on me. At one point, she was straddling me and before I could stop her, she pulled my tits out of my bikini tub and started massaging them. At that point, I didn’t want her to stop so I didn’t try to stop her. The massage led to us making out, her sucking on my nipples, which then led to me sucking on her nipples. I could see out of the corner of my eye the other three were just sitting there playing with each other and watching us at this point.

The girl on top of me stood up, and I just left my tits out. She stripped completely naked and started to grind on me again. She eventually put her feet on either side of me, stood up putting her pussy in my face. I was so horny at this point I wanted to eat her out so I did just that. While I’m eating her pussy, I feel my pussy start to get rubbed a little bit and then my bikini bottom getting pulled to the side. I glanced between her legs and saw the guy of the other couple on his knees in front of me stroking himself and the other two fucking. He looked at me almost asking permission, and when I didn’t say anything, slid himself inside me. I ate her out while he fucked me for about a minute or so before I felt terrible. I made him stop, telling him he could eat me out but not fuck me(it made sense in my head at the time). He was pretty respectful but said he was hoping to cum for me. To be completely honest, I really wanted him to as well. And I was aching to have him back inside of me. The girl I had been eating out, was not helpful and grabbed his cock, rubbing it up and down before I couldn’t stand it anymore. He ended up taking turns on us until he came. I was so ashamed I practically ran back to our houseboat after the horniness wore off. My boyfriend was fast asleep in our bed and I about lost it in the shower with guilt.

I feel absolutely horrible, but also think it was one of the hottest experiences in my life. I feel so bad because I know how badly my boyfriend wants a threesome. I just can’t stand the thought of him with another girl to allow it even after what I did.
