If you haven't fantasized about that ONE HOT encounter yet, I can only assume your imagination is yet to be unleashed. I have had one fantasy for many many years now. It is quite simple and involves a Fishing Boat and a Hung Stud.
There is something tantalizing with the combination of sex & water. I love watching a hot guy splash about in the ocean, the motion of his muscles, the glistening of his body as the sunlight hits that wet taut physique.
When I was 17 I first started having this fantasy. It first began one night as I was doing the dishes after visiting my Aunt for dinner. She was divorced but had a fella she was smitten with. While I was standing with my back to the doorway, scrubbing away in the sink. I heard my name called.
There was my Aunts boyfriend standing in the door way fresh after showering. When I turned to look he spread his towel open to reveal his semi erect manhood. My first impression was "Fuck that's nice"
(I am getting hard just recalling that moment) He stood there for a moment gave it a bit of a jiggle and then walked away. The dishes took a little longer than usual, his antic left a marked impression in my own pants. I was barely aware that I was gay back then but I knew I liked what I saw.

He was a keen fisherman, always out on his boat and so I began to imagine him fishing naked with his cock throbbing. I imagined me sitting there watching him, wanting to take his cock in my mouth and show him how much I wanted it. He was 35 at the time. Rugged, tall and the sexiest legs I have ever seen on a man. He had that light hair that seemed to shine when the sun hit it just at the right angle. And an incredibly nice dick.
I wanted so badly to ask him to take me out on the boat but knew my parents would never allow it, they had the knowledge of knowing I hated fishing back then and would not understand my dire need to go all of a sudden.
I don't really know why he decided to flash his cock at me that day but I am sure glad that he did for it provided me with some ball busting fun back then when I knew little about gay sex and how to get it.
All I know is that I wanted to taste his pleasure. It consumed my adolescence.
