When I was young, I got a job lifeguarding at a resort. I was 17 and as horny as anything. One of my jobs was to clean and maintain the womens dressing room, which was seperated by a wall from the mens area. There was a mutual drain for excess water in a slot under the common wall. There was only about an inch of free space, so it wasn't possible to get my eye down close enough to the floor to see into the women's side from the men's side....BUT one day I found a piece of broken mirror and placed it on the drain cover. Oh boy, now I could see everything.
One cloudy day, there was nobody in the pool and I was bored, but then a beautiful girl of 16 or so came in and I got the view of my life when she changed out of her swim suit before leaving. I had a rock hard dick and was looking for some way to get off other than just the normal hand thing. Ahhha, my megaphone had a smooth hole just the right diameter! So I shoved it in and casually leaned against the bottom half of the half door where I could keep an eye on the pool gate and started to slowly get a rhythm. When it was just throbbing, that beautiful girl came back through the gate, only 20 feet away. She never saw it, but my wad flew out of the big end of the megaphone and darn near hit me in the chin!!!
