His Fantasy:
We are on a black sand beach on some island. It is pretty hot, but there is a cool breeze coming off the ocean. We are alone on the island, dropped there for three days by helicopter. There is a small hut at the edge of the jungle looking over the beach where we are staying. We brought our own food with us and are supplementing with coconuts and some kind of small banana that grows on the island. There is a fresh water stream running near the hut. You can hear and feel the surf hitting the beach from the hut.
We have been lying out on the beach all morning and I am watching microscopic beads of sweat build up on the fine hairs in the small of Your back. I'm thinking about licking them off as I realize how hard my cock has become and the way the breeze feels on it. We aren't wearing any clothes so it's a little different.
I notice the sunscreen tube lying next to you and figure this is a great Way to get my hands on you. You still haven't noticed how horny I have become. I put a very large amount of the white cream in my hand and rub my two hands together to distribute it. I straddle your legs trying not to poke you with my cock. I place my hands on your shoulders and draw down slowly, spreading my hands to cover as much surface area as possible. It's slippery smooth as my hands reach your mid-back. As I feel your hip bones slide by my hands my cock hardens even more. I'm looking at your ass, my cock hovering inches above it, and the white cream tracks down your back as my hands slide over your cheeks and my thumbs pass between them. My cock spasms again and a drop of semen lands at the cleft at the top of your ass.
That gets your attention. Your hand comes back and grabs my cock as if to verify what you already knew. I want you so bad! You pull the head of my cock down to the small puddle of semen collecting in between your cheeks. It is very slippery and you are rubbing it up and down between your cheeks. I lie down over you so the head of my cock dives down between your legs. As it slips between your lips I feel the moist heat I love so much. I'm not entering you, just sliding between your lips with the tip of my cock bumping into your clit on each stroke. I hear you moan as I accelerate and then you cum for the first time.
You raise your hips slightly which changes the angle just enough for my cock to enter you fully on the next stroke. It feels wonderfully hot and slippery. In that moment I almost cum. I pause to regain my composure and we are off to some serious fucking. You cum 3 more times while on your stomach, then you push back onto all fours and I sit back on my heels. You sit up straight, turn around facing me and begin to bounce up and down riding me.
I watch you ride up and down on me against the background of the green trees, blue sky and black sand. I feel the sunscreen running down your back, over your hips and ass, and dripping on my cock as it slides in and out of you. I'm going wild slamming into you, meeting you each time you come down on me by thrusting up as deep inside you as I can get.
