It was the early fifties. I was a fourteen year old boy who had taken the El downtown specifically to visit a game arcade where I could spend my paper selling money on the games. While there I saw one or two machines which served as the video of that day.They were machines which showed a series of pictures which, when flipped briskly, appeared to show motion...they were actually pretty good.
Anyway, I found one machine which piqued my interest. On it were very pretty ladies who appeared to undress! (that alone was pretty risque for Blue nosed Boston). I remember hoping above hope that I could see a naked breast (at the time I was breast crazy because my older sister had such big and apparently beautiful ones...) I hoped above hope that I could actually see a nipple, which I had never seen on any woman.
Suddenly, the pics went from teasing ones, hinting but not showing, to a woman who went much further. I saw her remove her bra and show her breasts and..yes..her nipples! I was nearly to the point of total disbelief when, with no hesitation, she showed her thick black bush...I could not believe it!
Then, my money ran out.
On the way home, I took the lead car on the elevated railway, and stood at the front where you could stand and look ahead down the track, your back to the rest of the car and the people seated there. My mind was on fire with what I had just seen and I just had to touch my hard dick. I thereupon reached into the pocket of my raincoat and through a small unrepaired hole there (which I feverishly enlarged) and opened my fly and stroked myself through my underwear. I almost passed out when I came milliseconds later, filling my briefs with my semen, gobs and gobs of it..more than I have ever come in my whole life (and I am now in my sixties). I suspect some in the train knew what I had done..I received some very sharp stares from several women when I finally turned around to leave.
I was forced to spend the rest of the trip, a long trolley ride, with my crotch and legs and belly covered with cum, cold and dripping. I don't remember what I did when I got home...probably threw my underwear away...and I don't know what my mother must have thought when she washed my trousers and had my raincoat dry cleaned.
But, it remains the finest, most intense orgasm of my life....
