I was a married college student, in my mid-twenties, back in the 1970s. My first semester in school I was exploring the campus and was on the second floor of the Student Union. The entire second floor was virtually deserted as I wandered the halls.
I had the urge to pee and found a men's room tucked away down a short, dead-end hallway. I went inside and stepped up to the wall of six urinals, standing next to the marble wall of the first of about a dozen toilette stalls. I unzipped and pulled out my soft penis and cut loose. I glanced over at the stall and noticed a hole, about the size of a nickel, had been drilled through the marble wall, aligned directly level with my zipper. This was my first experience with such a peep hole in a public restroom.
While standing there with my penis in my hand, and a steady stream of urine hitting the back of the urinal, I then noticed the light reflecting through the hole, suddenly turned dark. I suspected someone sitting on the commode, in the stall, was now peeking through and watching me urinate. Well, my thoughts and imagination got the best of me and they immediately caused me to start getting an erection. I finished peeing, but decided not to immediately zip up. I made a conscious decision to play along with this voyeur, and began shake my penis, and stroke myself, as if I was knocking off the final drops of urine. As I did so, my erection began to grow, and I became even more sexually aroused, just thinking about the guy on the other side of the wall, and what he must be seeing and doing himself.
By now, I had developed a full erection. I was amazed at how hard I got. I felt extra-large and long, and was proud of showing off my perfectly circumcised penis, swelling to a full bloated size, the blood filling my thick, six-inch shaft and shiny plum sized glans. I could no longer withstand the temptation and began to masturbate.
Within just a few seconds, my orgasm built to the point of no return, and I began to ejaculate into the urinal, with long thick streams of semen. I turned slightly to the side to ensure whoever was watching me could see every detail. After shaking off the remaining drops of sperm, I placed my still swollen penis back into my pants and zipped up and left.
I had a light headed feeling as I walked to the stairs and back down to the busy first floor of the student union. My thoughts were that I would again visit that men's room in the near future.
Two days later I was back on campus. After my 8:00 am class, I had about an hour to kill before my next class. I decided to head back over the Student Union and check out that deserted men's room again. I could feel the beginning of an erection, in anticipation of what I might discover.
When I entered the restroom, I bent down and looked under the stalls. There was about 12 inches between the stall walls and the floor, and I could tell all of the stalls were empty. I was a bit disappointed, but decided to enter a stall about half way down, and upon entering, I saw there were those peep holes drilled through both walls, so that you could look into either stall and see anyone seated on the commode.
I closed the door and locked the latch, and dropped my pants to the floor and sat down. I casually played with my semi-erection. After about five minutes, I heard the restroom door open and heard footsteps. Whoever it was walked down to the stall on my right side and entered. I could hear him loosening his belt and unzipping, and bent over slightly and saw him drop his pants to the floor. Just then I heard the outer restroom door open again, and another man walked down and entered the same stall to my right. There were now two men in the same stall.
I heard a belt buckle being undone, and another zipper opening. I leaned forward and looked under the wall and the second man was standing, facing the man sitting on the commode. I peeked through the peep hole and I could see a black man sitting on the toilette and he was leaning forward sucking the penis of the other man who was white. The white man was holding the head of the black man as he continued to suck on his erection. Soon, I could hear the white man begin to groan that he was coming, and the sounds of an ejaculation and moaning could be heard. When it was all over, the white man zipped up and left. Now it was just me and the black man sitting side by side.
