I love this site. I have been reading it for years, but until now never got around to contributing. I love masturbating, and still do it about twice a day, even though I am married.

This happened a few years ago when I was about 18/19. I was home from college, and very bored and horny.

My aunt, Elaine, was in her mid-forties at the time, and was average both in terms of looks and build. She is about 5'4", shortish bold hair (dyed), not skinny, but not too plump either. She has a few extra pounds on her hips and ass, but nothing more than you would expect of a lady her age. Her breasts are about B/C cup. She has never been married. Before this incident I had never really thought about her sexually.

My aunt invited me to go to the gym/health spa where she is a member, one morning. I do a lot of sport, and was a quite bored at home, so I accepted.

It was a week day, and the place was almost entirely empty. We hit the gym first, and then the swimming pool, which was completely deserted. After a few laps of the pool, I went to the hot tub, and then the steam room, where my aunt joined me.

There was no-one else in there, so we were both lying down on the benches, I had my eyes closed. After a few minutes I was in a world of my own, and had completely forgotten that anyone else was there. Subconsciously I put my hand down my swimming trunks, and started to play with my balls. (I always find speedos too restrictive). I wasn't masturbating, just fondling, but I was starting to get a hard on. At this point my aunt coughed, and asked "Are you enjoying yourself?". I was a bit stunned, and just sat there. My cock, was still beneath my speedo, and not fully hard. I saw that she was staring at it, so I asked, if she liked what she saw. She said "yes", so I asked if she would like to see some more. She didn't say anything, so I just pulled my cock out, which was beginning to get hard. I was stroking it gently, showing it to her. Her eyes were fixed on it.

I'm not much of an exhibitionist, but I was really turned on by Elaine watching me. I completely lost my inhibition, and just went for it. I was taken by the moment. I stood up in front of her, and started to display myself to her. It was an incredible turn on. My cock was rock hard by now, and with my speedos tucked underneath my balls, it really stood to attention. (My cock is average size, about 6.5 inches, uncut cleanly shaved, and with nice big balls. In those days I worked out a lot and was very muscular).

I took my throbbing dick in my hand, and started to gently stroke it. All this time she did not speak a word. I asked, if she would like to touch it, as I took her hand and wrapped it around my shaft. She started to softly run her hand up and down. I was gently thrusting my hips back and forth. She worked my rock hard throbbing cock like and expert. (Although she had never explicitly had a husband or boyfriend that I can remember, she definitely had some experience, and knew how to take care of a man's needs.)

I asked her to show me her tits, so she took them out of her bathing suit. Elaine's breasts were quite saggy, but still a beautiful sight. I reached forward to have a feel of them, and they were soft and moist from the steam, but her nipples were hard and stood out like bullets. I was in ecstasy. The feel of her soft wet saggy boobs was sending me over the edge. I knew that I was close to blowing my load, moaned and my cock suddenly exploded. Five or six massive ropes of white hot cum shoot forward, and splattered my aunt's face and chest, running down into her cleavage.

I can still envisage Elaine sitting there covered in my jizz, with her saggy boobs hanging out.

I am not sure whether it was the taboo of a sexual experience with a relative, the sheer thrill of being naked in a public place, or the exhibitionism of showing my cock to someone, but this was possibly the most erotic thing I have ever experienced.

I quickly slipped my cock back into my speedo, and we each went back to the changing rooms. I was still incredibly horny, and jacked off again in the showers, with the image of her in my mind.

On the way back, I asked if she had enjoyed it. She replied "Yes, it was very impressive". We never talked about this incident again, and have never done anything else. Although anytime I see her I still get the uncontrollable urge to masturbate. I hope that she enjoyed it as much as I did.

I would love to hear any comments. Hopefully I will get time to write some more contributions.

Happy jacking.
