Part 1.
When I was 22 years old, I began boarding with a woman in a city distant from my hometown. I had just begun a new job, having been laid off for a few months in my own town. I was trying to rebuild my funds to pay for my own apartment and pay off some old bills. My mother had contacted an old friend and arranged for me to live with her until I got back on my feet financially.
I was obsessed then with females of any kind. Mary, older than me, was certainly not a sex goddess. She was a bit more than twice my age and was very matronly in form with wide hips and large, pendulous breasts. Her only child, a daughter, was working and living in California. Mary was also a widow of more than five years, and my board payments helped her increase her income from her own wages.
What shocked me, when I arrived, was that Mary bore a very strong resemblance to my own mother. She laughed when I mentioned this to her and told me that people used to think that she and my mother were sisters when they were young girls. Within a few days of moving in, I perceived that Mary was treating me like her own child, increasing the motherly image in my mind.
"Do you mind if I call you 'son?' instead of Walter," Mary asked one day while setting out our breakfast.
"No, not at all, but why?" I replied.
"I always wanted a little boy, but I had only my daughter."
"Could I call you 'mom'?" I asked; an inner perversity had caused me to ask for that right.
Just a slight pause, then she said, "Of course, son."
I had recently read some stories about younger guys and older women having sex; some even dealt with guys fucking their own mothers. I was fantasizing at times about having sex with Mary, and I would let my eyes roam over her when she wasn't looking. All I dared was look because I was afraid that she would kick me out and tell my mother if I tried anything. Perhaps I was attracted to her because I had no friends yet, male or female, in this new city. My former girlfriend had split soon after I had been laid off. I was horny as hell, I was obsessed with Mary, and I constantly thought about pressing myself against her ample naked curves. These evil thoughts only increased my horniness and helped me masturbate with greater pleasure, and now we were "mom" and "son."
When Mary would serve our supper in her kitchen, I would sneak looks at her while pretending to read the paper. I could watch her body move under her clothing as she bent, reached, and turned. Breakfast was even better. She was always in a robe over a thin nightgown with bare legs and feet. Just two thin garments lay between my eyes and her naked body, and I could detect large nipples under the cloth. Sometimes I had trouble rising from the table due to an immense boner. We had somehow started referring to each other as "mommy" and "my baby boy."
I could imagine her large breasts hanging over my face as she rode my hard cock. Mary probably had giant nipples, like thumbs, that I could latch my mouth onto. She could suffocate me with those large, soft boobs, and I would die willingly in a state of erotic bliss.
Her mothering me and her resemblance to my own mother gave my obsession a stimulating incestuous twist. I realized quickly that this made my fantasy even more exciting. My lust was driving me nuts. I had to have her soon, no matter what the risk. I even began to think of ways to rape her or drug her and schemed how I could get away with it.
Mary was a quiet, somewhat reclusive woman, and other than her work, she never got out much except for shopping or a dinner and movie with a few lady friends. She had never married again because she was a bit shy and didn't take many opportunities to meet men. She would often tell me that one friend or another would talk about fixing her up with someone, but she would always say that she believed herself to be too unattractive. If she had only known her effect on me!
I imagined that Mary needed to have her pussy opened up again, like a virgin, after so many years of disuse. My fantasy now contained the double excitement of fucking both my new mother and a virgin at the same time.
Mary had occasional headaches, and I began offering to massage her neck and shoulders to help drive them off. My eager manipulations were, although amateurish, successful, and soon my hands roved over her neck, shoulders, and back whenever she needed my attention. Usually Mary would be seated for these massages, but occasionally she would be standing and I would be pressed against her back. By keeping my mind on my fingers, I avoided probing her buttocks with my hardening cock.
Mary, having lived alone for so long, often bathed or dressed with doors partly opened. If I were careful, I could see her now and then as she undressed or washed herself. A couple of times I could see her in the tub from the crack of my door. I would masturbate there, watching her wash her body and shooting my load onto the back of the door. My obsession was really driving me crazy, I began jerking off a couple of times a night, and I just couldn't get her out of my mind. I didn't care about the young babes any more.
I was awakened in the middle of the night by the light in the bathroom. When I pushed open the door, Mary was standing there pressing a wet washcloth against her head. I noticed that she was dressed only in a thin nightgown, which clung to her curvy body, showing me the heavenly shapes beneath.
"Baby, my head hurts again. Could you please rub my neck for a while?" she whispered, seeing me standing there.
"Of course, mommy," I answered. I moved behind her and began kneading her neck. We were now both facing the mirror over the sink, and I could see her eyes were closed as she enjoyed my fingers on her neck. After a few minutes, Mary began to make little purring noises, and my fingers roved widely over new areas of her soft, smooth skin.
