Tayrona National Park in Colombia has the only nudist beach there. It is at the far end of a popular and beautiful Caribbean coast. The National Park is a major tourist attraction, but secretly for a shy exhibitionist like me that nudist beach was a major draw.

Already when planning the trip I had this strange feeling in my belly, an indicator of nervousness, anticipation, with a mixture of sexual excitement and dread.

The trip there is quite an adventure; you have to walk two hours through the jungle and along some popular tourist beaches, clamber some rocks until you get to the nudist beach, a long stretch of white sand with some hilly forest cover behind and at the far end.

When I finally got there, I took off my swimsuit, enjoying the sun on my ass and shaved cock. Immediately that belly feeling set in again. There I was, craving an adventure and dreading it at the same time, but hoping for people attracted to my naked body and excited about the possibilities that may lead to a hot encounter and wary of possible disappointments. I knew the nudist "crowd" would be at the far end, so I grabbed my bag, striding on that beach, wearing nothing but a Panama hat, eager to reach that end.

My belly excitement soon travelled down into my balls and dangling cock which got bigger with every step closer to the naked human beings that I could start to make out.

I slowed down to enjoy people looking at me, straight couples, gay couples sunbathing and me parading in front of them, not sure what to do, but hornier by the minute. I particularly enjoyed some appreciative glances at my half-erect cock. I felt both creepy and excited.

I thought about masturbating, of course not in direct sight of people; it was, after all, a nudist beach not a sex club.

At the same time I was hoping to attract someone, no matter who, a couple, a woman or a man, that mixed feeling in my belly was getting acute, something had to happen, I couldn't just lie down to sunbathe.

So I proceeded slowly to the end of the beach, having passed everyone there. I headed toward a tree-clad hill with some big rocks in front. Clearly there would be ample possibilities for a hidden encounter if only someone would follow me. The way I paraded slowly should be - so I thought - an open invitation for anyone who was interested to follow me.

In the worst case I could just relieve my tension behind a rock and rejoin the sunbathers with a reddish cock and emptied balls.

I passed a few rocks and went up a hill with a bit of a view and sat on a tree trunk. I was beyond horny and started to rub my swelling cock. I felt a little disappointed that it seemed to all end in a bit of an anti-climax, a lone masturbation, though at least in nature with a view of naked people at a distance.

I was busily caressing my erection when I heard a sound. I looked up and saw a young man at a short distance staring at me. He was of course naked. I smiled at him then looked at his body - he had a full erection, but was not touching it.

This electrified me. He had a hard-on from watching me. The exhibitionist in me was jubilant.

I continued wanking while looking at him. He continued staring at me, clearly fascinated by the sight of a naked man masturbating his big cock and continuing to do so despite his interruption.

He didn't move. He just stared. His cock pointing skywards. He didn't touch it.

I gazed at his thick hard cock enjoying that beautiful expression of his attention and his stare at my own exposed naked excitement. My own cock was rock hard, a swollen pride, as I was continuing playing seductively with it and with my balls - my legs spread for the stranger to enjoy the best view.

My belly feeling was now pure excitement, no more dread. Actually, I craved for the stranger to come over and suck me off.

But he just continued staring. He seemed shy, maybe because he was young. But his hard-on stimulated me.

I made a sign with my hand inviting him over. He seemed hesitant, moved a bit closer and kept watching me stroking my big excited cock for him.

I was super-hot and on edge. A climax was approaching. But would it be a climax with the young stranger? Or just jerking myself off under his gaze?

Just as these thoughts crossed my mind and I was invitingly waving my left hand, the young stranger decided it was none of the above. He moved away, still hard, but almost like fleeing the proposed encounter.

My almost bursting cock sent a wave of disappointment up my belly.

But I was beyond just masturbating alone on my tree trunk. I got up, my erect cock pointing towards the beach.

I clambered around the big rocks back on the sandy stretch where a dozen couples and individuals were sunbathing and walked past them. My penis was still hard for everyone to see and I enjoyed the looks and glances as I paraded my horniness under the sun.

I went behind a bush that was giving the right mix of decency and visibility (for anyone who wanted to look between the twigs and leaves) and jerked my craving cock. I felt the eyes of a couple on the other side of the bush and that pushed me over the edge!

My hard red cock exploded in my right hand and shot several loads of cum on the leaves of the bush.

I can't remember whether I moaned or not, but somehow I now felt an urge to leave the scene of my semi-public masturbation.

I emerged from behind the bush, my dangling cock still dripping droplets of cum and I made my way to the sea to take a refreshing dip. I needed it as I was still burning with excitement.

The feeling in my belly was now a mixture of excitement, pride and satisfaction.
