During my senior year in high school, I worked part time at a large furniture store. I was a very fit athlete and worked out daily at that age. I used to work in the warehouse, and always wore shorts and a tank top in those days. We had a mid forties bookkeeper that was constantly throwing out sexual innuendo at me, complimenting my physique, and occasionally touching my body (not the privates) in a sensual way. She also went out of her way to rub her big tits against me every chance she could. I was good with girls my age at that time, but I was somewhat naïve and simply had no game when it came to grown women. Looking back, she was relentless with me, but I simply didn't know how to respond to her. This was back in the late seventies, you never heard of 40 plus year old women and teenage boys hooking up. I enjoyed all her attention, and fantasized about her almost every night when I rubbed one off. She was a tall, slender woman with a huge natural rack on such a slim frame. I just couldn't believe that she actually wanted me. I just thought she was having a little fun with me. I was scared that if I came back on to her, it would scare her away and all the attention she was giving me would stop.
One day when I was about to leave work, she had purchased a makeup table and asked me to bring it out to her car. She knew I only lived a mile or so from her home, and asked if I would come by and assemble it for her later that evening. Still not expecting to get laid, (but hoping) I was very excited to be invited to her home. Went home, showered, and put on my skimpiest tank top and shorts. Got to her house and she was wearing a pair of cut off Daisy Dukes and a little spaghetti strap top, no bra, and her hair was still wet from just getting out of the shower. I had never seen her looking so sexy. She invited me in and gave me a big lingering hug for coming over to help her. She looked so damn hot in that little outfit, and smelled so damn good, I got instant wood while we stood there and shared a little small talk. I can't remember all of the exact verbal exchange, but in a joking way, she said something to the effect of, "You should have never worn those little shorts over here, do you know how easily I could peel those shorts right off of you?" For the first time, I said something to the effect of, "Please do." Without saying another word, she started kissing me passionately and grabbing my dick through the material in those little silk shorts. She literally started pulling off my tank top and shorts within under a minute. I was more turned on than I had ever been in my life, and probably since! Ha, my "rub off" fantasy was coming true. It was even better than I had ever imagined. I doubt a full minute and a half had passed, and she practically dragged me to her couch and pulled me on top of her. I was butt naked and she was still fully clothed. She was all over me, moaning and kissing me passionately while grinding those little shorts up against my dick. She was so aggressive with me, it was almost like she had gotten out of women's prison. She started aggressively stroking my rock hard dick. Within probably thirty seconds, I knew I was just a stroke or two away from busting a nut. Even at that age, I had been sexually active with girls my age, and I knew cumming at this stage was going to be extremely embarrassing. I reached down and pulled her hand away from my dick. I guess she got the hint, but immediately started grinding against me. I bet she only thrust her hips against me three or four times and I came all over her little shorts. I couldn't have been more embarrassed! She was very understanding, even pretended to be a little flattered, and we proceeded to the bedroom. Once she stripped out of her clothes, I bet I was fully erect in another minute or so. Her body was even better than I had ever fantasized. And her divorced pussy was as tight as any girl I had ever been with. Poor gal, we fucked four times that night. I doubt I lasted more than a few minutes the first three times. Finally, on the fourth fuck it took me forever to cum, and she got properly fucked. Or, at least as properly as I knew how in those days. Long story short, we fucked almost every evening for months. Even saw her occasionally throughout college and right up until I met the gal I was going to marry. I learned a lot from her. I still look back on her as my best sexual partner ever.
On an amusing note, I got divorced at 39 years old. Like most guys, as soon as you get separated, you immediately begin to think of all you potential sexual partners. I immediately thought of her, than I quickly thought about the math. She would have been in her mid sixties. I never made the call. I almost regret not making the call, who knows, she may have still been a hot piece of ass.
Sorry about turning this into a novel, but I still look back on that as one of the hottest memories from my youth.
