Carol and I had just finished putting new exhaust manifold gaskets on the boat so we decided to take it out on the river for a test run. After years of helping me fix my toys, she has become a great helper with fixing my cars, motorcycles and the boat. Her first husband needed help changing a light bulb, so she was surprised that she understood how these things worked and enjoyed solving problems.
For out test run, she put on a skimpy two piece that just barely covered her large nipples, which she thinks are too big, and showed off her beautiful 34DD tits. She covered herself in a white mesh beach cover-up that showed off what she had on underneath. Her shoulder length blonde hair needed no care for a day on the boat. At 5'10" she is a good water skier and has beautiful legs and tan to show for it.
As we were getting ready to leave our friend Greg drove up, I invited him to come out on the boat with us. She gave me a suspicious look. We had never been with him sexually, but he had been part of an MFM with a past girlfriend of mine so I knew he would be OK if things took that direction with Carol while we were on the boat. He has a good sized cock, not as long as mine but much thicker, and I hoped to see it in Carol's mouth today. Carol and I have talked and fantasized about a threesome many times during sex, but this would be her first time.
Greg liked to cook and had cooked great dinners for us a few times. After dinners we usually had a few drinks and he would always flirt, compliment and stand close enough to touch her back or arms as they talked. This never seemed to bother Carol, as she didn't move away. I think it was her way of making story subjects for when we were in bed, not to mention she could see it aroused him and that made it more fun and boosted her confidence. She knew he had seen the 'private' photos I'd taken of her and he had to be curious of what she looked like in the live flesh.
Greg was 10 years younger than Carol and in good shape. I didn't want her first time shared to be with a guy with a huge beer belly. That would have messed up my future recollection of the event. I had showed him photos of her on her knees looking up at me with her beautiful sparkly blue eyes wide open and my cock in her mouth and licking around the head. She knew how to put on a show for me and the camera. Other pictures I showed him were of her lifting her skirt and flashing her smoothly shaved pussy and big tits while standing next to our car at a strip club parking lot. As she put on the show she was oblivious of the people walking by behind her checking her out. There was another photo of her cum covered breasts as she smiled into the camera holding them up proudly. Greg and I had talked about it possibly being his cum instead of mine one day if he was lucky, so he knew what to hope for.
Greg was wearing denim shorts that were probably fine for working around the backyard, but showed a bit too much cock for public. He must have thought it would help with his flirting and to let her know what he had in his shorts.
The boat was a day cruiser with a seat across the front of the engine hatch/sundeck, seating along the right side like a lounge, and then a single captains barrel chair that swiveled.
We went out into the channel and slowly cruised for a while to let things warm up. After the engine was warmed up, I put it though it's paces just to make sure the repairs held. The boat performed flawlessly. Since we were now confident the boat was in great shape, we decided to cool off with a swim. I pulled into a secluded cove where no houses had been built yet. Carol and I have been back here before swimming nude, sucking and fucking on the deck. The idea of the occasional fisherman or jet skier discovering us in the throes of passion was part of the excitement for us. It had never happened, but she was nervous and excited at the same time about the idea of putting on a show for a stranger.
She had started flashing truckers after I showed her websites and forums about it. She would always call me when she was putting on a show for one of them and tell me what was going on and how much she was showing and what their reactions were.
After we anchored the boat in the cove, I opened the engine hatch to check for water or exhaust leaks, all seemed fine.
Carol said she was ready for a swim and took her cover-up off and stepped onto the sundeck and down to the swim platform.
I wondered if she was going to leave her bikini on or go nude as we have in the past. I guess since she hadn't ever been nude in front of Greg, she decided to keep the bikini on.
Greg and I enjoyed watching her body and I wondered what she would do next.
She turned to us and asked if we were just going to sit on the boat, she slid into the water.
I walked to the bow and dropped my trunks off and jumped in and gave Greg a thumbs up. He took off his shorts and was sporting a nice erection. He's single and it had been a while since he'd had any pussy. As Carol swam out a bit she went underwater and came up facing the sun and shaking her hair. It seemed like a scene from a movie. When she looked at Greg, he was standing on the swim platform with his cock standing straight out. She looked at it for a while but said nothing. Then she realized she was staring a bit too long at a man's cock. She finally asked if he was coming in to join us.
The water felt perfect, not cool like in the early spring or too warm like it gets in late Summer. The three of us talked, flirted and swam around in the water. I wrapped my arms around Carol and started kissing her and feeling her ass underwater.
She stopped me and said she felt funny with Greg watching us and being ignored.
I said he would probably feel better if she were also naked.
She started untying the neck tie of her top, she stooped down into the water and fiddled around a bit and then made a grand TA-DA, as she stood up with her large tits exposed. She moved closer to Greg and handed him her suit top and bottom to put back on the boat. She stood in front of him with her shoulders back showing off her tits. This was not her normal posture, as it was meant to highlight her tits. She then turned and swam over to me and grabbed my cock. She mentioned that I must be enjoying the idea of what might happen next.
We kissed some more and then I suggested she swim with Greg, she kissed me and winked. I was so excited.
I knew something new and fun was about to start, but still didn't know where the boundaries were and how far things would go. She knew what I liked to see from our private photos and watching and talking about my porn choices.
Greg looked lost like he didn't know what to do next, he didn't want to be pushy and mess things up.
Carol broke the ice by going right up to him pushing her tits against him and starting to make out.
He seemed shocked by how aggressive Carol was. She had one arm around his neck and the other underwater. I knew she was feeling and playing with his cock and balls. His balls are larger and looser than mine so I know it was a new feeling for her.
After a minute she broke the kiss and asked me if I was enjoying the show and how was she doing?
I told her she looked wonderful in another man's arms and wondering what was going on below the surface.
She knew I enjoyed her talking sexy so she told me how she was squeezing and stroking his fat cock and big balls, rubbing his cock up and down from her pussy lips to her clit and up on her tummy. She told me how different it felt from mine and wanted to get out of the water so she could explore it better.
They went back to the swim platform and she sat on it and spread her legs as he moved in between her thighs. They started kissing again while he played with her large nipples. The water was shallow enough that his cock was out of the water and I saw that her hand with her shiny wedding ring was still wrapped around it as she stroked and pulled him closer to her wet cunt by his cock.
He started to rub the head of his cock against her clit and pushing a little at her opening.
She said "Let's get on the boat before we go too far."
They were ready and I now knew all our sex talk scenes and fantasies were actually going to happen. They climbed up onto the sundeck and I followed. I went to our junk bag to get the camera. As I pulled the camera from the bag, she only asked that I not show them to anybody she knew or post them online.
Carol then asked me if I was really sure I wanted her to be another man's slut. A word she told me a few years ago was disgusting, now she was using it. Of course she knew the answer. She was just having fun saying the words because she never spoke like that except to turn me on. She told him she wanted his fat cock in her mouth first. She was now on her knees with her ass in the air and her knees spread far apart for me. She took his hands and put them on her head and told him to grab her hair to show her how he wanted to use her mouth. He let her start on her own, kissing the head while looking into his eyes, into my eyes and the camera lens, then licking the sides and rubbing it around her cheeks, lips and forehead. She fondled his balls and asked if he wanted her to suck them.
Greg said "Oh yeah."
She slid down and began sucking his nut sack and swirled her tongue all around his balls, then lifted them up and slowly sucked one, then the other into her mouth.
I knew all too well what he was feeling, as she was doing things to him that she does to me.
