A boat called cuckcruiser

I am very fortunate in some ways, but not in others. My wife is beautiful, but boring!! After years of trying to spice things up I have given up on the idea. However I do get plenty from other sources, both men and women, so I don't complain and being blessed with an above average sized cock, neither do they!!
I am also lucky financially, being able to afford a nice villa and boat in the med.

Recently I was alone on my boat after a morning fishing and decided to anchor in a local bay to take in some rays and do a little swimming.
It was a hot day and all was well with the world. Swimming past one anchored boat, I was more than a little surprised at the name on the transom...cuckcruiser and even in the water my cock started to twitch and my mind raced.

On board was a couple, she at about 45 and he was about 50, my age and both quite attractive. Although the bay was known for nude bathing, they both had bottoms on, but no tops and her breasts were beautiful and bronzed from the sun.
Their boarding ladder was down so I thought what the hell!! I boarded onto the bathing platform and he looked at me very defensively saying 'can I help you' I don't know what came over me but I just looked at his wife and dropped my swim shorts, right there on the back of his boat. Even though I had been swimming, I was so excited that there was little shrinkage and she looked at my cock and licked her lips, he on the other hand just stood and stuttered, mmmmay I get you a take.
I said yes and started to move over towards Dorothy, his wife.

As he went below to get our takes, she stood up and came towards me, looked directly into my eyes and sank to he knees. We weer in plain view of other boats but she didn't care, taking my expanding cock, she cupped it in her hands and moving forward, opened her full lips and took the head into her mouth.

At that moment Jack, her husband came with the takes, saw his wife sucking on my cock and just looked in awe, a little stiffy (and I mean little) forming in his swim trunks. It was obvious why he named his boat cuckcruiser, Jack didn't have enough to keep Dorothy happy that's for sure.

It was then that Dorothy utteed her first words 'give our guest his take Jack, then sit dowm and don't play with that pathetic excuse for a cock, I am going to enjoy this one' Then returning her attemntions to my cock, she licked the uncut tip, pulled back my foreskin and licked all the way down to my balls.

and then??
