I was daydreaming, thinking about holding that ass in my hands, watching Denver go by when she returned. She plopped into her seat and pulled out the ...ards."What'll it be?" she asked."Your choice," I told her.We played cards for a while until the train started its long climb into the Rockies. At first it was a gentle rise over low foothills. But soons we were in the mountains themselves, up in the pines and aspens. We both were watching as much as we were playing. The conductor came on and. Slowly it developed in a sexual desire with the years.But didn’t have the courage to take it forward, I used to go to their house when she is washing clothes and see her boobs as they are wet and when she is feeding her son.This went on for years then finally the day came and I got the chance to touch her boobs.I always try to get a chance to sit next to her, lie on her lap, touch her when ever possible. We went as a family to my native after me completing my college and I was lying on the bed. After we came, she said, “Now that’s what I want a man to do after he fucks my ass. Thank God.” For the next three weeks she habituated my ass to her fingers, then to her dildo, which she would cover with a condom and work into me as she sucked me. At the end of the three weeks she fucked me up the ass as I rode her fast and hard. Her thighs were up over my shoulders and she reached behind me with both hands to slowly push the dildo inside me as I entered her. When it was in, she turned the end. I've never done it that way.” She turned over on the bed and presented her behind to me as she was face down on the bed. I couldn't help but marvel over what had happened in the course of just over an hour...A request for demonstration sex by my neighbor lady! Her body was not my style being so slender, but she had hidden assets that made that a moot point. I approached her slight behind, thinking she is made for doggie sex...her inviting pussy beckoned me to enter. As my throbbing knob made.
