It started on a hot glorious sunny day. I had recently traded in my yacht for a Catamaran hoping my wife would try it. She hated the yacht and to my annoyance she decided that she wasn't even going to set foot on the cat. As with the yacht I had mates that would sail with me and we often fished off of it. Our friends Carol and Brett had never been on a yacht let alone a cat and when I mentioned it they jumped at the chance of a weekend on it with me. So Friday lunchtime we cast off and slowly motored out the harbor and into the open sea. We hadn't been out more that an hour and Brett was looking green around the gills. He battled on for an hour or so and then he was as sick as a dog. I thought he would have one good technicolor yawn and then would be ok. How wrong I was. He seemed to get worse and instead of heading for our original destination I diverted to a small bay I know, where there's access to a small town . It was fairly sheltered and now the boat wasn't heeling over, and he could see land, he picked up. I dropped anchor and sails, then dropped the tender into the water. We all headed into the beach and walked up through the small town. Bret seemed ok so Carol suggested that if we got some food in us he might be ok, and at first he seemed better with food in him. Then after a walk around we headed back to the tender and the cat. It was just beginning to get dark and I made sure we were locked down for the night. There are two cabins on the cat, but the second one needs some work done so I was using the seats in the lounge that turn into a beds, and Carol and Brett was in the good cabin. We had barely been settled down for an hour when Brett rushed past me and up on deck and chucked his meal into the sea. He was followed by Carol who appeared in a flimsy nighty. I don't think she expected to be running around the cat in the nigh in her nighty. I made a note of how good she looked in it. Brett declared that he felt better for chucking up and just wanted to go to sleep. Carol and I got him back in the cabin with a bucket in case he was bad again. I had put the kettle on for a cup of tea and Carol sat with me and I made her a hot chocolate. Then we could hear Brett snoring. He was finally settled. Carol didn't want to go back into the cabin and disturb Brett so opted for the other seats and I collapsed them for her into a bed. We both settled down, listening to Brett snoring for England. Although it was hot during the day, on a boat it can get pretty cold and quickly. Suddenly Carol was up and at my bed and climbing on next to me with her quilt. I lay there thinking about seeing Carol in her tight shorts and even tighter T shirt on deck earlier in the day and then in her flimsy nighty. The vision of the swelling of her boobs wouldn't leave my mind and I lay thinking she had gone to sleep and listening to Brett still snoring. Then one of her hands touched my knee and it was cold. I jumped just a little and she seemed to move with me and her hand was on my knee again. I could feel my cock throbbing in my pants, knowing that her hand was not far from my cock only made matters worse. Then she moved again. Now most of her cold body was snuggled up to mine. I lay still not wanting to disturb her or loose contact with her gorgeous body. She was warming up or I was cooling down, but we were at a more comparable temperature. Then Carol rolled over onto her back and the quilt had moved and I was able to see the bulge of her tits in the moonlight through her nighty. My cock was now getting beyond uncomfortable. Then it happened. Her hand landed on my cock. She sort of groaned and then moved it again. Now it had now gone down the front of my pants and was holding my hard cock. Then suddenly she sat bolt upright and let go of my cock and pulled her hand away. "I'm sorry, I forgot where I was," she apologized. I told her not to be worry or be sorry and that I was just beginning to enjoy it. I could see she thought for a few minutes. Then she lay back down and her hand returned to my cock. "Did I do that?" she asked. I told her that she had and as I lay there she started to move her hand and wank my cock. "I'd better do something about it or neither of us will be able to sleep," she added. I was happy to get a hand job and relaxed to enjoy it. After several minutes she tried to change hands but it was awkward for her. Then suddenly she was moving again and this time she ducked under the duvets and sucked my cock into her mouth. It was still awkward for her so she moved again and now we were in the sixty nine position as she sucked my cock deep into her mouth. She gave a sigh as she sucked it in deep. Now being face to face with her panty covered pussy, I could smell her pussy. It smelt so good that I couldn't resist pulling the flimsy material to one side and push my tongue into her pussy. Carol made a sort of gurgling sound as my tongue touched her clitoris. I was now lapping at it as she bobbed her head up and down my cock. We had been like this for quiet a few minutes when Carol took my cock from her mouth and said, "Fuck it." She turned her body round the same way as mine again. Being on top it was no problem for her to raise herself a little and penetrate herself on my cock. She groaned as it sunk deep into her sex. Then she was riding me. I reached for the swellings of her breasts and mauled them as she rode me. In the little bit of light from the moon I could see that she was biting her lower lip as she groaned and rode on. Then she groaned loudly and froze. I guessed that she had come. As she tried to fall forward I held her up right by her tits as I bucked my hips to reach my own climax. Eventually I reached the pinnacle as I pumped my load deep into her pussy. carol let out a final groan as I lowered her onto me. We lay like that for a good five minutes with my cock still buried in her pussy. Eventually she rolled off me and we lay side by side sweating from our endeavors. I was soon asleep. Carol woke me about seven o'clock in the morning as she left my bed and went back to the other bed. I could still hear Brett snoring. About an hour later he emerged from the cabin, looking fit for a marathon. He declared he was ready for anything. Carol went to their cabin to change for the day and I dressed while she was gone. Brett looked ok as I sorted breakfast and drinks. Afterwards he helped clear up and stow everything. I asked did they want to go on to our original destination or return to my home harbor. Brett to my surprise opted for going on thinking he would be ok now. Carol assisted in preparing the cat and getting underway. She had the helm and we had barely been sailing for an hour when Brett was back over the side chucking up. I could see that Carol was annoyed with him and went to tend to him as I took the helm back. Shortly we were in sight of the harbor we were heading for and Brett picked up when he could see that we were approaching the harbor. As we approached I called the harbor master for a day berth as we would have to sail back later that day if we were going to get back by nightfall. We moored up and went ashore where we had some food and I found where the bus went from to get back to my home harbor. We put Brett on the bus, and went back to the cat as the bus moved away. It was just Carol and I now. We motored out the harbor and Carol had the helm as I rigged the cat for some hard sailing and found we were on a good Beam Reach and covering lots of ground. As carol stood at the wheel I stood behind her and reached around her and cupped her tits. Carol groaned as I mauled at them. Then she groaned even more as I slipped a hand down her shorts and slipped a couple of fingers into her pussy. Carol was pumping her hips at my fingers. I took my hand off her tits for a moment to lock the boat on course with the Auto Helm. Now I could do with carol what I wished, so long as I kept and eye open around the boat. As Carol still held the wheel as I pulled her shorts and panties down. Then releasing my cock I penetrated her from behind while she held onto the wheel. This was something I had often fantasized about fucking a woman whilst sailing. It also seemed to float Carol's boat as she was thrusting back hard onto my cock as I slammed into her pussy. It got even more exciting when in the distance there was another yacht coming towards us and there was the possibility that they could possibly see what we were doing. Carol came quite violently and at the last second she fell away from me, and I came all over her arse legs and shorts. As soon as she was able she rushed down below to clean up and put some clean shorts on. She returned and stood with me as the other yacht passed us, waving to them. Later as I had the helm Carol dropped to her knees and sucked me off. I think that was my best BJ ever. Then we were sailing into the harbor and Carol had the helm as I dropped and packed the sails. By the time we motored to my berth Brett was sat waiting for us. "What kept you," he joked. It was a while before everything was done and we could leave the cat and drive back home. We stopped for fish and chips on the way home. As we waited for them I joked with Brett asking when he wanted to go again. He was quick to say that he would never ever get on a yacht again. Carol said that she would have to come on her own with me if I would take her again. Since that weekend Carol has been my regular sailing partner and Brett spends his weekend with my wife on dry land. They even traveled down to Looe on one occasion to meet up with us. My wife and Brett surprised me when they stayed in a hotel whilst Carol and I almost slept on the boat. We were planning a trip to Jersey where Carol and I would take the cat, and they would fly there to meet us there, and sleep on the boat in the harbor with us. Covid has put paid to that for the time being, but it will happen.
