Jennifer

This time without the restraints of my shorts, my dick stood straight up and throbbed.
I reached down and wrapped my fingers around my shaft, gently and slowly stroking myself and picturing Jennifer in my head.
I thought back to that day, when I had caught her and my dad together. I removed the image of my father, on his knees, and replaced it with an image of myself. On my knees. Sucking and gagging on Jennifer's massive cock.
I pictured her throwing me onto the bed, landing face first and her yanking my shorts down to my ankles. Climbing behind me and lining her cock up with my ass, sliding deep into me and fucking me like an animal.
I groaned and shuttered, my cock twitched and I sprayed my load all over the shower wall. Heaving and panting, I leaned on the wall for support as my legs trembled underneath of me. I relaxed, cracking my neck and reaching for the soap, trying to forget about the thoughts that had just brought me to an orgasm.
Little did I know, just outside the bathroom door, my step-mother had been listening as I had groaned and moaned in the shower. She had peeked through the door and watched me, through the glass shower stall. Stroking her own cock as she admired the sight before her and licking her lips, with lust.
Over the next couple of days, Jennifer and I did not see too much of each other. She was busy with work and had also been to a few meetings with her lawyer, regarding the divorce papers that she planned to serve to my father. When we did see each other though, we would shoot each other odd glances. I caught her "checking me out" again, on a number of occasions and I was certain, she must have noticed me doing the same thing. I wondered what she thought about that, though.
Late one Friday night, I was on my way up the stairs to my bedroom, to call it a night. As I walked down the hallway towards my door, I passed the bathroom door and heard what sounded like, crying. It wasn't out of the ordinary; not anymore. On a few occasions in the last month, I had caught Jennifer crying over my father. I was always there to try and comfort her and make her feel better, whenever I found her in these conditions.
