Taking my cock in her hand Karen guided it straight to the target and watched as Sheri took all I had right up to the hair on my belly. Karen ran her ...inger tips around Sheri’s puckered hole to feel my slippery cock moved in and out slowly. Karen sat back and watched while fingering her own pussy. So Karen masturbated as I fucked Sheri to a screaming climax. A few weeks later Sheri told us she was going to take a job at the local Dodge Dealership and she was also thinking of moving out to an. .. a slave. Could it be? Is this what she really wanted? Was this why my little sister hadn't had a steady boyfriend? Because none of them would treat her like this?I reached out and ran the end of the ridding crop over her naked butt cheeks.

Her breathing was becoming faster with each pass of the crop over her ass.I. 'Damn it; maybe I am jealous. I don't even know for sure that they are having sex in there, but I feel jealous now. Why do I feel that way? I'm married to his dad, but did I get some feelings for him when I sucked his cock, and he shot his load on my face and boobs?'I stayed there and listened as carefully as I could."Fuck, you are praising her now, Gabe. She has to be giving you head now," I groaned, bringing my right hand to the knob.I turned it and opened the door up somewhat. 'I knew it,. I fumbled for my cock and within a few short strokes I shot my load 2 or 3 meters across the bathroom, then crumpled in a heap on the floor licking and kissing the place where her pussy had been. Since that day I had been able to repeat that event only a couple of times but the longing and the lust for this woman never diminished. This was my chance I thought to myself, my mother was dead so she'd never know it would be our secret. She was still sexually active if what my mother had told me.
