When I was 15, I began to visit adult cinemas. In the dark I secretly masturbated watching the porn and after an hour shooting it in a handkerchief. After several visits I was keen enough to look around. I noticed to my astonishment, that many men were moving down there with busy hands. Then I saw the first stiffy gleaming in the dim light. I couldn't refrain to wank openly too. After a while one of the visitors bowed and held a paper hanky before him. He ejaculated happily. Then a second did the same. I was the third. I was scared and came back after a year first, when my urge to watch porn got irresistible.
Then I saw for the first time in my life real intercourse: The boy on my right side was sucked by a gentleman. In 5 minutes he stretched and moaned quietly. I knew, that he was pumping his twirling tadpoles into the man's mouth. I had an involuntary emission and splattered my trousers. I fled embarrassed.
Now I go to live shows, where one can jerk off undisturbed. I concentrate on the lips and clit of the girls, when their legs are spread and off it goes. Sometimes I use the solo cubicle, where the girl is forced to see your nasty doing, as there is no one-way pane. I like it so much. Thus my pocket money is blown out of my purple dick head.
