Rachel was a very attractive girl, just 19 and every bit as stunning as any girl he had ever known. The fact she was his step-daughter made things a little more complicated. He had married Rachel's Mum just a month earlier and while he had met Rachel a couple of times he had never really got to spend any time with her until after the wedding when her real Dad decided that he was going to move to Canada and it would be best for Rachel to live with her Mum and me.
This suited us fine, but as I said it made things a little more complicated for me when I realized just how beautiful she was. Rachel has short brown hair, which she has feathered into her round sweet face, framing her grey slate eyes and soft puffy red lips, she's relatively short at just 5'6", but she has barely any weight on her other than round her hips and her chest which although small is perfectly formed and seems to defy gravity, like her peachy round ass. God how I love it when she stays over on hot weekends, lazing out on the lawn and traipsing through the house in just her bikini or what there is of the material and string combo that is her excuse for swimwear.
Sometimes I found myself just getting hard watching her, feeling my cock grow in my pants as I fantasized about her sweet young body. I'd have to run off to the bathroom and jerk off straightaway, sometimes I'd go to the downstairs washroom and dig through the laundry, picking out her dirty underwear, smelling the gusset, wrapping the material around my cock and pumping my thick load into them, imagining that her tight snatch had been in them maybe only a few hours before. Of course I always got a guilt trip afterwards and felt like a pervert for letching over my step daughter, but that didn't stop me from pretending I was fucking Rachel while I pushed my cock into my wife's juicy wet pussy.
One night while I lay up watching a movie, sprawled out on the sofa in just my boxer shorts and a dressing gown that had fallen open, Rachel comes in. She's all like "oh hey dad, I just couldn't sleep", her hair all messy and her eyes half shut still as she stands there in this tiny night dress she has, barely covering her sexy little thighs.
"Oh poor baby" I say "why don't you come over here and sit with Daddy we can watch this movie together 'till you get tired". She smiles at this and comes over sitting on the sofa then curling up next to me her cute ass spooning into my lap as I stretch an arm over her waist, draping it there as we watch the film.
