I was 12 and on holiday with my family, We spent most of our time on the beach, There was plenty for me to explore cliffs full of caves and rockpools aplenty, It was on one of my frequent explorations that what I am about to tell you happened, I was quite a way from my parents happily exploring a new section of beach when a man came over to me and started to chat to me, He was tall in his forties balding but with a nice smile, He wore a pair of yellow swimming trunks that hid little as they were so tight, He chatted away as I hunted in the rockpools then he told me he knee where some good pools were in s nearby cave and he would show me if I wanted him to, I jumped at the chance and followed him to the cave, As we entered I bent to look into a pool and I heard him say "Hey look" I looked up and he stood there with his trunks pulled down and his penis on show, I didn't know what to say or do but stare, He started to stroke it slowly as he looked at me after a few seconds he told me to touch it as I knelt bathe pool I was mesmerised I reached up and touched it I have no idea why I just did, It felt warm and kinda nice to the touch he groaned as my fingers ran over it, Suddenly he took my hand and wrapped my fingers around it and showed me how to pump it, The tip became wet and shiny as my hand slid up and down it, Then he stopped me and told me to stand up as I did he slipped his hand down the front of my trunks taking hold of my penis and stroking it with his fingers I remember how nice it felt and how it made my own penis hard, Although it was small he breathed in a husky voice that it was a lovely prick, Suddenly his free hand went down the back of my trunks and cupped and squeezed my bum check firmly then I felt his fingertip on my bumhole I was shocked at first but relaxed as it started to feel nice, He then stopped and yanked my trunks down exposing me to the air and his gaze he bent down and started to lick and suck my now hard Penis it felt marvellous tingles came in waves all over my balls making me shudder his hands grasped my bum cheeks firmly as he slurped and sucked noisily, Suddenly I felt myself shudder and my whole body stiffen it felt as if I wanted to pee but I was too far gone to stop I steadied myself on his shoulder in case I fell, I didn't know it then but I'd had my first dry orgasm, He then stood up and told me to suck him I knelt and opened my mouth as he slid the head of his penis in I started to suck it as he had done to me it tasted salty but kind of nice so I carried on he groaned gasped and grunted loudly telling me what a sweet boy I was, Suddenly something warm and thick shot into my mouth he told me to swallow it growling it rather than telling me, I swallowed as fast as I could some escaped down my chin onto my chest though, When he recovered we dressed properly again and arranged to meet there again the next day, That holiday was better than expected I spent a lot of time with him even in his holiday caravan nearby he taught me a lot and I loved it especially when he licked my bumhole, On our last meeting he fingered me while I sucked him he also tried to fuck me but I was too tight and it hurt too much even though I wanted him to, Despite that it was the best childhood holiday ever.
