I’d like to share an experience with you and your readers. I’m sure many women have conjured visions of sex with a perfect stranger.

Well, it really happened to me, under conditions that I never would have imagined.

It was a few years back. I was working my way through college by substituting as a gym instructor. The offices of the instructors were located on the mezzanine level of the gym. We each had a little cubbyhole to call an office.

One day, I was searching for some old paperwork stored in boxes along the wall of my office. When I came upon the box that I wanted, I couldn’t get it down because it was glued to a piece of tape attached to the wall.

As I moved closer, I could see that at one time or another, someone had enlarged the hole. A bright light was streaming through. In unthinking curiosity, I looked through the hole. I saw that it overlooked the men’s shower room. The room was empty except for one man who was showering near the center of the room. Instinctively, I pulled back, but the sight of his rather large cock ecentually drew me back to the peephole.

The man was very good looking, with a well-muscled body. His broad shoulders and chest tapered to a slim waist. His stomach muscles rippled as he rubbed soap over his body. He had strong, brown hands and bulging biceps. I was fascinated as I watched his hands drop lower to lather the pubic hair surrounding his dangling cock. Breathlessly, I watched him run the soap over his prick and balls. I recognized his face. Ironically enough, it was the head instructor. I began to imagine those same fingers running all over my cunt.

With a will seemingly of their own, my fingers suddenly dug under the waistband of my gym shorts to probe my cunt, which was getting more than a little wet. As my hot box got wetter, I rubbed the slippery stuff up over my excited and protruding clit.

The man was now applying soap to his dick, which was no longer dangling. It was sticking straight out from his body. As he applied more soap, his hand formed a fist around the shaft of his stiff, erect penis. He slowly, lovingly caressed it in a rhythmic pumping action. My own finger followed his rhythm in and out of my oozing cunt and over my hardening clit. I let out a soft moan.

I heard a slight noise behind me, then a voice said, “Please don’t turn around. I’d like this to be a mystery to remember.” I felt his hands on my hips and his fingers pulling at my shorts. I sucked in my breath. I couldn’t believe that this was happening to me, but I didn’t want it to stop. He asked me if I liked what I saw in the shower. He said that he had one just like it. I could have it. All I had to do was ask.

“Please,” I moaned feverishly, “give it to me, now! I don’t care who you are. I only want your cock.” I could tell from the voice that he wasn’t one of the instructors or one of the substitutes. It was an unfamiliar voice. The cock pressing into the small of my back was throbbing. I could feel the hot weight of it. I wanted it inside me.

“I’m new here,” he said. “I just came to see one of the trainers. I never dreamed that she would look like you. Here you are, all alone and horny. Here I am to assist you.” By this time, he had my shorts and panties pulled down around my ankles. He reached under my bare ass and began to finger my wet cunt. I didn’t want to move. I let him do it all. I was too horny for him to stop now. I could feel his pulsating cock against the skin of my bare ass.

He held my pussy wide open with one hand while he eased a finger in my cunt until I thought I would come. He slowly and expertly drew it out far enough to tantalize my yearning clit.

I wiggled and waved my ass violently, keeping in time with his vibrating finger. As soon as I slowed a bit, in one motion he pulled his finger away to thrust his cock inside my pussy.

I managed to keep my eye level with the peephole while he fucked me from behind. I couldn’t help but watch the man in the shower. He was pumping his prick faster. Suddenly, he slowed down. I could tell that he was making an effort to prolong the rapture that he was undergoing. The action in my cunt was following the same pattern — faster and faster, then slowing down for control.

This wasn’t the first time I had been fucked in this position, but the circumstances were so exciting. The hands behind me reached forward to hold my jiggling tits, now loose of my bra. He manipulated my nipples so that an electric current raced down to my crotch and into my pussy to enhance the fiery frenzy boiling in my cunt. I was close to coming, but I wanted to hold back. I looked through the peephole to divert my interest. I wanted to enjoy the tingling in my pussy as long as I could. I wanted my final climax to last as long as possible. I hoped htat it would never end.

The man in the shower grasped his cock, holding it tightly at the base. Then, raising high on his toes, he arched his back and sprayed his stream of thick, milky come into the air. At the same time, two wildly related things took place. My own orgasm burst joyously through my body. My erupting juices streamed down to mingle with the come of the cock inside me. All three of us came to a harmonious climax at precisely the same instant.

The man in the shower held his now-shriveling prick in his hand and let the cascading water of the shower cleanse it of its liquid. The man behind me slowly withdrew his shriveling cock from my cooling hot box. He leaned heavily against my ass, panting. My knees almost buckled as I wearily braced myself against the boxes. After a few moments of rest with his balls pressing against my ass, he pulled away. “When I came looking for the trainer, I never expected a hot fuck,” he said.

I could hear him putting on his pants and buckling his belt. I felt his lips move right beside my ear, his warm breath tickling my earlobe and neck. “Don’t move, now,” he said. “I want to be able to surprise you again sometime. It won’t be the same if you recognize me.” I could see the wisdom in his suggestion. He was the best that I had had in a long time. I had no idea who he was, and this just added to the excitement.

I heard the door slam shut behind me. I listened for his step as he hurried down the stairs. I needed something to recognize him by.
