(Probably should check out "What happens on the boat, Pt. 1, before you read this...)
After five solid hours of debauchery (the French term for fucking and sucking) on a huge cabin cruiser, we were back on our friend's big sailboat and heading home, with more than 100+ miles of gulf to cover at 5 or 6 knots.
I'm Bill. My wife is Marilyn, early 50's, sexually adventurous. She's bi, I'm working on it. Swinging together for the last four years, since we met. The other couple, John, 60'ish owns the boat, Linda,50'ish girlfriend. He runs marathons for fun and is a blue water sailor. She is long-legged and an athletic blonde, no tan lines.
We'd just visited that bigger boat from Biloxi, a 60' cabin cruiser with three very horny couples. We were sexually exhausted from taking multiple new partners that afternoon. We were still nude, but showered off, the girls still dripping cum as I stuck my finger in my wife for a taste.
"Yummy" I said, "That is a new flavor, isn't it?"
John said, "I think that's mine!" and Linda stuck a finger into Marilyn, coated her finger, and tasted "That's John alright; I know that flavor anywhere!" Marilyn had at least three men come in her pussy in the last few hours and two of us in her mouth, and another woman started working on the cream pie.
With everyone smiling, I told folks I was heading to the bow cabin for a nap before I took the 9-midnight watch. Kissed Marilyn and grabbed my shorts off the deck. I could hear them chatting as I drifted off.
A warm body and tender arms wrapped around me in a few hours. "This is nice" Linda said. It was dark, I was full-on awake, as she was licking my neck (always gives me chills) and reaching around, grabbing my cock and balls in one hand, with a tender squeeze. "Marilyn said you liked to wake up like this". And I just gave a moan and smiled. She continued to roll on top of me, still nude. We had yet to have sex, but she was changing that and just dropped down on my erection and started riding. My cock was a little tender, but after 5-7 minutes we had pretty much a mutual orgasm. Hers first, mine in a few more strokes. "Must be my watch" I mumbled, as I rolled over, my cock still dripping, grabbed a shirt and shorts, gave her a quick peck, and headed to the cockpit.
"Cockpit" was accurate. Marilyn was on her knees, a greedy woman with John's cock down her throat. She has excellent skills in that department.
"Hey kids, don't let me interrupt things..." They got themselves together, she kissed me long and hard with the flavor of Johns cock on her lips and tongue, a quick "Love you" as she headed below. John briefed me as I put on a life vest and clicked on a safety line (Gotta have 'em for night watches). Nothing showing on the radar of any interest, the weather was good, and in a couple of minutes, Marilyn starts moaning from the captain's cabin, right below the helm. And then some thumping. When having sex, she was inspirational. You wanted to please her, and the more you gave, the more she wanted. The noise continued for 15-20 minutes or so and slacked off. Quiet on the water. Lots of stars out.
I stayed awake, with little or nothing to do until after midnight, the boat on auto-pilot, and Linda had the watch, so I went forward to wake her. Bunk was empty. The head was empty, but the captain's queen-sized bed was full of people.
Linda on the closest side, so I gave her the same wake up with a tongue in the ear and talking dirty "Hey sailor, wanna fuck" and she gave a small moan, opened her eyes, disentangled from John & Marilyn, and I went back topside.
She came up with her shirt and shorts in-hand. Nothing to brief, we were just twenty miles closer to home. She snapped on the life jacket and safety line, dropped down to the swim platform and peed into the gulf. I joined her.
