A step mother's sin - Ch. 1: invading his privacy

... through security, he picked me up as he hugged me and spun me around like a rag doll. Since my apartment only had the one bedroom, a loft of sorts that overlooked the living area, the plan was for Robert to sleep on the couch for the summer. And since the living room was not actually isolated from the bedroom, I bought a high quality set of head phones so Robert could watch TV at night after I had gone to bed without disturbing me. Robert would not have a vehicle for the summer, but I had arranged a local gym membership so he could work out during the day to stay in shape. As a college student, he did not have a curfew, but I asked him to be courteous of the fact that I had to work. But the rules were virtually non-existent. We typically ate dinner together. Then we would move to the living room, and we would watch together TV until I retired to bed, at which time Robert would don the headphones and watch TV until he decided to turn in. On an evening during the first week Robert was here, I awoke around one a.m. and decided to go down stairs for a drink of water or juice. I slept in my panties and a tee shirt. As I descended the steps from the loft, I could see the glow from the TV illuminating the room and Robert was lying back on the couch with his headphones on. His back was to me.

I found myself getting aroused at this sight, and without thinking, I reached down and touched myself while standing in the shadows, watching my son pump his fist. After a few moment, I silently slid my fingers inside the waist band of my panties and gently massaged my erect clitoris as I watched Robert continue to stroke himself. I hoped he would ejaculate while I watched. I do not know exactly how long I stood there in the dark, squatting slightly and silently stimulating myself to the incredible and unexpected sight of Robert's masturbation session, but I assume it was several minutes. I do not know what made him do so, perhaps he saw my movement behind him reflected on the TV screen, but suddenly and without any warning, Robert tuned around and saw me standing in the darkened hallway with my night shirt hiked up around my waist and my hand inside my panties stoking myself. “What the hell?” he exclaimed. I quickly withdrew my hand, tried to straighten my night shirt, and explained that I was only coming down for a drink. I apologized for disturbing him, quickly scurrying into the kitchen. I could feel the embarrassment and flush burning my cheeks; my pulse was racing as I quickly thought what to do next. Robert ...
