"You think I don't know a whore when I see one!? Laying there with your filthy legs apart and abusing yourself with a hairbrush!!?"He slapped my face,...then backhanded it the other direction, then slapped it again. I saw stars as my head whipped from side to side."You are a worthless whore!!" Then how come you got a hard-on!?" I sobbed.Well, of course I wasn't thinking straight. I mean, my mind was all flustered and dazed from being slapped and the shock and humilation of being caught like that.. Not that I was complaining...I'm Mikey, or Dan depending on who I'm with at the time, Dan being my deceased Granddad and the apple of my still living Gran's eye. So much so that she ended up seducing me to take my 'conjugal rights' with her as a substitute for her Dan. Gran has a form of dementia which leaves her confused as to where she is, how old she is or who is her family, living or not. She's still a lovely old lady but you never quite know who you're talking to, Grace that is, or Grace. She looked serious. Serious and sad."You going to pull me from the contest?" I asked sullenly.She gave me a look I couldn't read. "I've thought about it. What do you think? Do you want to quit?"I rolled over and sat up in bed. "I've thought about it, too." I reached out and took a sip of the coffee she had brought. "If it means anything, I don't like what I did last night. It wasn't very nice." I didn't elaborate."I would hope not." She held up her hands, stopping my response. "No, no one said. I felt her squeezing her pussy around my fingers, massaging her slippery inner walls as she bumped and rubbed her clit against my palm. Grinding her pussy with the rhythm of my finger-fucking, Susan grasped my Hard shaft, feeling my cock throb for her. Her soft hand stroked and squeezed along my length, making me grow harder for her. She occasionally paused her up-stroke to swirl her thumb over my swollen tip, teasing out my pre-cum. Wetting her fingers with my pre-cum, she lightly caressed her.
