“Put you hands behind your head.” She complied slowly, nervously, but she complied.I sat down on the nearest settee to me so that I could look her...over. Gill could not be called a beauty. At twenty three or so, her face was more than passable, but the slightness of frame and her timidity did nothing for her. It indicated a narrowness of mind, even shrewishness. That was probably unfair, but an accurate description of the persona she projected.Gill’s skin was almost flawless; a small brown mole. She didn't allow me to enter her pussy, so I just rubbed myself in her ass crack, using the flesh of her ass cheeks to rub against! I continued thrusting between my own mother ass cheeks, faster and harder, until I, finally, came with a groan of pleasure. I watched my cum fill her ass crack, and all over her fat arse cheeks.I laid back and relaxed, enjoying the after-glow of another fantasy about my mom's fat ass. 'If only it could become a reality' I thought to myself. I closed my eyes, and. Mum, you smell nice, as always," he muttered dreamily and turned over and went back to sleep.My mind was full of emotions, and I felt weak in my knees. I sat down on his bed, stroking his hair and looking down on his handsome features. Conflicting emotions washed over me. I realised that my own son was sexually arousing me. My maternal instincts were being challenged by feelings of pure lust and my dormant libido. I was in a torment and didn't know what to do. I sat there for a few more. After classes I had to go back to my locker and get a book I needed.Marjorie offered to go with me, but I said to her, "No need, I'll be backhere in a moment." Stupid me, I hadn't counted on some people waiting fora chance like this.As I closed my locker with my free hand, the book I had needed was knockedfrom my other hand. Angrily I turned to the one who did that and started,"What the hell do you ..."My voice trailed off as I saw Gary Fields and Phil Bondi with SheilaTarkin behind them.
