I have always been a legs man and love the winter when woman clad them in tights or stockings. Recently when entering my local supermarket I noticed a large lady with great legs. She was well proportioned and wore a mans black V neck jumper, showing ample cleavage, a short denim skirt, patterned tights and high heels. I couldn't keep my eyes off her legs and she caught me looking and smiled wickedly. As I progressed around the supermarket she always appeared to be within my sight. While checking out some chicken I felt her presence beside me. She picked up a packed of chicken and said "Leg or breast?", I replied "Leg", "Thought so" she replied and put the packet back. I carried on shopping and saw her again on several occassions, each time getting a cheeky grin. Having completed my shop I went to the check-out and paid. After leaving I noticed her waiting outside and walked towards her. "Want to see more"?, "Yes Please". She instructed me to follow her in my car. She drove about three miles to a local beauty spot. I pulled my car next to her's and she opened her window. "Get into the backseat of my car, push the front seat forward and await the rules". I did as instructed. The rules were as follows; Rule one, I was to sit with my hands behind my back at all times. Rule Two, I was not to touch her. Rule Three, she could do to me what she wanted, Rule Four, when she was finished I would get in my car and leave. She got into the back of the car and pushed the other seat forward, I followed rule one and put my hands behind my back. She turned herself towards me and lifted her jumper, she had huge tits and you could see the strain on her black bra straps. She gently caressed her tits. By now my cock was rising and she noticed and smiled. She then lifted her bum from the seat and slowly started to pull her skirt up, revealing more and more of her great legs. eventually her skirt was right up and I could see her lacy black knickers through the patterned tights. She ran her hand over her legs, thighs and crotch. My cock was now aching to be released. She then leant forward and undid her bra, her mamoth tits spilled out, she lifted her bra to show me her huge nipples, how I wanted to lean across and suck them. She slid towards me, unzipped my flies and pulled my erect cock from my boxers and gently started to stroke it, I felt helpless but couldn't bring my hands from behind my back, eventually she got up a good rythm and was really working my cock before I shouted "I'm cumming" and shot my load over her hand. She instructed me to clean myself up and leave. Over the following weeks we followed the same procedure, only things progressed, she put her tits to my mouth so I could suck her massive nips, she gave me a blow job and finally this week pulled her tights and knickers down and sat on my erect cock, I was still sitting with my hands behind my back totally powerless, and that's what makes it such a turn on. I look forward to shopping next week.
