This is my first post and I would like to share an incident that happened a few years ago before I remarried. I am wondering if anything similar has ever happened to anyone else. I was a cargo pilot for the Air Force and would usually return to my home base late on Friday Nights. I love to go to the gym near my apartment to sit in the sauna and relax after such a long 10 hour flight. Even though the fitness center had a sign stated open "24 hours" it actually did close at midnight on Fridays only, but it was usually very empty on a Friday night. To my surprise when I entered the dry sauna, there was a very attractive brunette sitting there with a towel wrapped around her from her breast to her thighs. She saw me enter the gym in my flight suit and we talked about the usual stuff for a while. She was happily married and just in the area for a hair dressing class. From my first impression of her, she seemed like one of those perfect people… perfect looks, perfect personality with no flaws and strong moral values. When it got close to midnight and they flashed the lights in the gym I told her that we would have to leave soon. She thought it was open all night. I told her that if she wanted to stay, we could sit in the corner of the sauna and the workers never check in back of the sauna….and we could turn the sauna back on after everyone leaves and go out the back door. (I had done this a few times myself but only alone). There was not much room in the corner of the sauna... and she sat on the bench that was higher than me. She had to prop her legs up and my face was near the bottom part of her thighs and even though her legs were together I could see she slight glimpse….she was wearing a thin type of thong panty underneath, but then again she never expected to sit like that esp. close to me. I could not help to get very aroused and in my loose shorts it was very noticeable. We sat quietly for a few minutes and somebody came in to turn off the sauna heat and lights and of course did not check around the corner. The people who worked at the gym were always in a hurry to leave on Friday nights and before we knew it were completely alone in a semi dark sauna. I turned the heat back on when I stood up, it was very noticeable that I was very aroused. And of course the issue of sex came up in our discussion. She told me that she would never ever cheat on her husband and I can understand her and respect her feelings. But we shared very intimate details of our past experiences. Since we were both strangers it was like we could discuss the most intimate details without any feeling of guilt or shame. I told her about one of my secret fantasies that happened in high school (in fact I had never told anyone about this fantasy). I told her about the time when I was 15 years old and in class. When the bell rang, the girl who sat behind me squatted down over to get her books under her desk while I was turning around at the right time, since she was wearing a very short dress and a thin panty. I saw up her dress and thru her thin panty. It was my first time to see the details of a female. Although there was some hair matted against her panty, I could see the slit and the clitoris that was only a few feet away from my face. I told the married woman that even till today, if I remember what I saw I still get very aroused. I told her that it was my fantasy to go back in time.... and freeze time to that instance, and look close and masturbate. She told me, that when she was young, she saw through the bathroom crack late in the door late at night, her brother’s friend masturbating. She told me it was the first time she saw a penis in real life and she wanted to watch more, but to shy. She said it was the very first time she really very wet. She said she even tried to massage her clitoris that night but did not have an orgasm by masturbating until a few years later. She also told me that the site of a man masturbating has always got her aroused and the first time she had a orgasm masturbating… was remembering what she saw in an x rated movie… seeing a guy shot his load on a woman’s tits while jerking off. She said she asked her husband to masturbate for her once, but he thought it was some kind of joke and said “why do I need to masturbate when I have you”. I told her that once I read an article about how people who had some very embarrassing situations of getting caught masturbating and early ages, feel very insecure about it for a very long time. I told her that I see no harm in masturbating for her and all she had to do is watch. The only light in the sauna was from the exit light near the door and since it was quite dark I walked around the corner turn the lights on and when I came back around, she was sitting in a position that revealed her panty. She was sitting on the second level bench with one foot on the lower bench and one foot on the same bench as her seat. Since her panty was wet and tight, it made the details very visible. Although her lips were a bit larger than the girls in high school, it was just the fascination of seeing something I was not supposed to see. She said something in the terms of “I know you are a gentlemen and there is nothing wrong with just watching”. I as I slide my shorts down to reveal my large penis, I told her to imagine that we are both invisible to each other. She responded that if that was the case, she would be rubbing her clit as well. I stood just in front of her (less than 2 feet) as I started to massage my hard penis. She kept her panty on and started to massage her clitoris from the outside of her panty as we watched each other closely. It was my first time to actually watch a female masturbate and was really making me even more aroused than just seeing something I was not supposed to see. She only used one finger over her clit and moved it a circular motion. I normally used lubrication when I masturbate alone, but this time I did not need it because there was so much pre-cum oozing out, it lubricated my swollen throbbing penis. After a few minutes I started to climax and I knew this was going to be one of those gushers that really shot out, esp. since I had not ejaculated in a couple of days. I started to breath heavy and squeezed the head of my penis harder as massaging it. I moaned that I was going to cum and as I did, she started rubbing her clit much faster as if she had complete control of her orgasm and was ready at any moment to let loose. The first shot of my sperm was not that much (only a small teaspoon’s worth) and shot landed on her thigh. Just as the second shot released with much more force, she was moaning with extreme pleasure and moved closer to me while keeping her one finger on her clitoris. My second shot of sperm must have been over a table spoon and streamed out and hit her towel above her waist. Just as the third shot started to shoot out, she grabbed the head of my penis and most of the 3rd shot cum must have hit her hand. I thought she was going to put it in her mouth the way she held it and leaned over but she brushed it up against her breast. She leaned over hand used enough force to push the towel away and let the head of my penis against her nipple. The last few shots of my cum went against her nipples and it was pure bliss for both of us. I would like to tell what happened after this incident cause there is more to this story but I have typed to much for now and don’t even know if anyone will even bother reading this far. But I am curious if anything similar has ever happened to anyone. And if there are anyone things what we did was considered cheating?
