WAITING FOR MY NEW s****r "TO COME" 1. SeXStoRY

It's been about four weeks since I last wrote to you. And I can say that it's been difficult living in my Dad's house the last couple of weeks. All I've been able to think about is when I can get into my Step Mom's knickers. I've been masturbating every time I've heard my Dad fucking her - and sometimes just at the thought of my Dad's cock getting inside her. And my Step Mom has been showing me pictures of her daughter, Sally, and that's has had me masturbating as well. Does my new Mom want me to fuck her daughter, I wonder? Does she see me as a potential son-in-law, as well as a "son"? Perhaps I'm still a bit inexperienced, but I find my Step Mom (like all women) very difficult to understand. Sometimes when I've seen her leaning over the sink and have tried to lift her skirt and get my hands down her knickers, it's as if I've been a nuisance to her. And whenever I've tried to watch her get undressed, she's always told me to leave the room. Then suddenly she'll surprise me, as she did last week at the local shopping mall. I was supposedly out with her to help bring back the shopping from the supermarket, but instead she took me on a tour of the ladies "intimate" section of the department store across the road. She seemed to want my reaction to the colours of panties and corsets. Did I like black, red, or white? Did I like thongs or full panties? And this time when I eagerly felt her bottom, hidden as we were between the racks of knickers and bras, she didn't shy away or go cold on me. She simply said, in the bedroom voice I recognized from listening to her with my Dad: "Come on, come on", and she led the way out of the store. We walked in total silence, both instinctively knowing exactly where we were going and what we were going to do. Or at least that's what I thought. I could feel my cock lengthening and hardening inside my pants as we walked to the car. I wasn't sure whether she wanted me to do it straight away in the car or not, and so I stupidly put my hands right up her skirt to her vagina lips and kissed her as soon as we were seated. "Stop it", she said, and I thought I'd made a mess of things again. But she went on, to my great surprise: "I want you in bed, you naughty boy". And we soon found ourselves in the nearest motel, down near the airport, with me hungry as hell for her tits and pussy. She was wearing black stockings and suspenders, as if she'd been planning this trip with me all along, and she used tricks on me she hadn't done before: like rippling her vagina walls up and down my cock as we sat upright on the bed kissing and cuddling, ready to do some serious fucking, and she sat on my face this time: the first time "Mom" had done that to me - moving from side to side to get my face completely covered in her flowing juices. She wanted me to suck her tits and call her "Mom", as if doing it with her husband's son got her turned on. Because I noticed that every time I called her Mom as I pushed my cock into her, it got her excited and I'd feel her vagina close around the hard shaft. TO BE CONTINUED.
