I pulled back and began to fuck her with long thrusts that pushed my cock all the way in.I kept fucking her as her pussy became slick and started gras...ing at my cock. She was wailing into the bed and jerking as she continued to thrust back while I fucked her. I knew I was going to pump cum into this girl as she twisted and shook, "oooohhhh!"I started fucking her hard and deep, with strokes that planted my cock each time. Star howled and tried to slip to the bed but I followed her as I continued. Standard digs for a junior executive engineer with a few degrees and a few lucky breaks. “Thanks”, I said as I pulled out my chair and fired up my computer like I was actually going to do something.“So,” my sister asked as she took up a position in my spare office chair, “What are you going to be doing today?”Talk about timing. Right when my sister said this Rebecca stepped in through my office door wearing her standard clothing. A short skirt, skin tight top with no hose and no bra.“Good. I swirl my tongue around. Once. Twice. Three times taking it in my mouth. I gently suck it as I rub myself through my jeans. My other tit cries for attention so I reluctantly let the other go. This time, I gently nip at it. I can feel my pussy growing wetter.I stop groping my tits and slide one hand into my pants. I gently toy at my clit. This time, I moan loudly. I slide my jeans off and fall backwards on my bed. I'd remove my underwear, but I never where it. My pussy is dripping. I couldn't look at my parents without that image popping up in my head. And I'd get myself off to that image frequently. At first it was Jimmy and the nameless woman. Then Jimmy started to fade out and my dad started to show up in his place. It was disgusting, yes. But not enough to make me stop my blissful fantasy. That kept happening over and over. I'd imagine Jimmy, but by the time I came, dad would be in his place. Always. Then my mum started creeping into the fantasy too because well,.
