Many years ago, when I was 16, I was out walking my dog around midnight. (It must have been a weekend, or during a school holiday, otherwise I wouldn't have been up at that hour!) I was passing through the local park where I usually walked the dog, and noticed a car parked up ahead in a clearing just off the main path. As I passed the car I glanced towards it and realised it was occupied. There was a man in the driver's seat; from what I could see he looked middle-aged and was wearing a suit, collar and tie. The seat was reclined slightly and I could just see the top of a woman's blonde head bobbing up and down in his lap. He was completely oblivious to my presence and, young and inexperienced as I was, it was obvious he was enjoying a blowjob from whoever the woman was. I gawped for a few seconds more, then resumed my walk, heart pounding as I pondered what I had seen. I walked on for perhaps four or five minutes and then retraced my steps. Sure enough the car was still there, but this time it was rocking up and down. I had another peek as I passed by but the windows were steamed up and I couldn't see anything. It was clear, however, from the noises coming from inside that the couple were now in the back seat and that things were approching a climax. Slightly disappointed that I hadn't seen more, I walked on and out of the park, back towards my house. As I turned into my street, the same car approached from another direction and stopped on the corner. The passenger door opened and a blonde woman got out, said goodnight to the driver and started walking down my street. As she crossed the road to my side of the pavement I saw, to my utter astonishment, that it was my next-door neighbour. She gave a start when she recognised me - I was gawping at her like a lunatic - but she managed a smile and a hello as we proceeded down the street together. I mumbled something about did she have a nice evening, and she mumbled something about a social event at her work. She was wearing a long coat, but I could see underneath she had on a fairly glamorous black cocktail dress, black nylons and high heels. All the time we were walking my mind was working furiously, thinking about what I had seen and balancing the fact that I liked this woman with the fact that I'd lusted after her all through puberty. As we entered a little lane that took us to our respective homes I finally blurted out "I saw what you were doing." She put one hand to her mouth and said "What do you mean?" Still not daring to look her in the eye, I said "In the park. In that car. I saw what you were doing." I heard her moan "Oh my God", then she took my elbow and halted us, there in the quiet lane. "Look," she said, "what you saw is none of your business. It was my boss, OK? And Frank (that was her husband) must never find out about it." I said nothing - probably because I couldn't think of anything sensible to say - but she must have misinterpreted my silence because she suddenly took hold of my shoulders and repeated, in a trembly voice clearly close to tears, that I absolutely must keep what I'd seen to myself. To this day I don't know how I mustered the courage to do what I did, but I reached out and drew apart her coat, and looked her body up and down, still saying nothing. If at that point she had said "Don't be silly!" and closed her coat I'm sure my nerve would have failed me and nothing more would have happened, but instead she said "Is that it? Is that what you want?" I nodded dumbly, not trusting myself not to squeak if I spoke, and unbelieveably, she nodded. I put my hands on her breasts and squeezed gently, feeling their softness and the contours of her bra under the thin material of her dress. As I kneaded her she reached down and unzipped me, then put one hand inside my trousers to withdraw my already hard cock. I slipped the straps of her dress, and her bra straps, offer her shoulders and, one at a time, lifted out her large breasts, looking down at their whiteness and the large brown nipples. She stroked my cock for a while, and said "Is that nice?" Emboldened now, I nodded and whispered "Yes, but not as nice as what you were doing to him." She closed her eyes for a few seconds, then, with a resigned look on her face, she bent down, took my cock in her mouth and started to suck me. I looked down and watched her blonde head moving up and down as she serviced me, relishing the feel of her full lips sliding up and down my engorged shaft. I wanted it to last forever, but of course my 16 year old body betrayed me and all too soon I felt that familiar rush and realised I was about to come. Some instinct made me put one hand on the back of her head just before my climax, and I suppose she must have realised what I was thinking because she made no attempt to pull away when I started to come, but carried on sucking until the last drop of spunk had been drained from me. When I took my hand away she withdrew my cock from her mouth and dribbled my semen onto the path, before standing up and readjusting her clothing. Her face was tear-stained but she was otherwise composed. The rest of the walk home was in silence but, just before we parted, she said, not looking at me "I hope I can rely on you to keep quiet about tonight?" I smiled and said "Sure ... if you play your cards right." Then she DID look at me, with a shocked expression on her face, but I didn't give her the chance to say anything else. I simply walked off into the night with a smile. (Watch this space for Part 2)
