It was late Friday night and I was hot, tired, relaxed and horny as hell.

I had just finished an aerobics workout and an hour on the gym equipment. I was standing under the shower letting the warm water wash away the rest of the weeks problems.

I thought I was alone in the gym except for the old maintenance man that locked up at 11 p.m. so I was surprised when I heard in noise in the locker room outside. Through the door I could see that it was one of the aerobics instructors. I think that her name was Kathleen or Kathryn but everybody called her Kat. She was the epitome of aerobic instructors, tall, blond, blue-eyed and very shapely.

The bathing area was quite large but only had three showers. From where I was standing with my head bowed and my back to the center shower the entrance to the room was to my right. I couldn't help but peek at her as she entered the bathing area. She caught me looking at her and smiled as she passed directly in front of me on her way to the shower at my left. I was immediately attracted to her so I returned her smile but quickly looked away, a little embarrassed. When she turned on the shower and stepped back to adjust the temperature I stole another glance at her. We were almost the same height but she was in far better shape than I. Her skin was a beautiful bronze color and unbroken by tan lines. It offered an outstanding contrast to her naturally blond hair. Her breasts stood out as they do only in drawings of beautiful women. I couldn't help but notice that her nipples appeared to be hard, I know that mine were. Again she caught me staring at her and smiled at me. I returned her smile and I am sure I blushed before I looked away.

I turned around to face the shower and tilted my head back to let the invigorating water cascade over my neck, shoulders and breasts. Although it felt wonderful it did nothing to alleviate my sexual urges and in fact only increased my needs as I thought of the beautiful woman next to me. When I peeked at her this time she was staring directly at me with a wide grin on her face. I quickly looked away but this time I could feel the heat on my face as I blushed. I turned my attention to the soothing waters that were rinsing the tension from my body.

I stood there for a few moments with my eyes closed when suddenly I felt hand on my left shoulder. This was quickly followed by second hand fondling my right breast from behind and a gentle kiss on my right shoulder. She pressed into me until I could feel her nipples boring into my back and the warmth of her body against my buttocks.

My first instinct was to escape but the wall with the showers was in front of me and she was almost surrounding me from behind. Besides, it felt good and I wasn't sure I wanted it to stop. Now both of her hands were on my breasts, fondling, kneading and tweaking. My already firm nipples were as hard as acorns and despite the hot shower I was covered with goose bumps. I made a snap decision and turned around to face her. My nipples brushed against hers and it was almost like an electric shock went through me. When her lips met mine and her tongue pushed into my mouth I felt a weakening in my knees and an exotic feeling as my pussy came alive with moisture. Without breaking our kiss or our embrace her right hand found its way down to my crotch and felt the dampness my pussy was producing. Slowly her lips left mine and without moving her hand from my pussy she lowered her head and took the nipple of my left breast into her mouth.
