New Little Sister

By ldtexas

My dad remarried not long ago, mom had left him quite a few years earlier, taking me with her. Recently she had hooked up with a new guy, he wanted mom all to himself and convinced mom to send me to live with my dad. Hell, I am 19 and in college, I told them all it was a bunch of bullshit and that I would just move out on my own, but my dad insisted I come stay with them, so I did.

Now, my new step-mom really wasn’t thrilled that I had come to live with them either. She and I didn’t get along very well, she was like mom’s new boyfriend, she wanted my dad to herself, hadn’t signed up for having me around when she married my dad. Best my dad could do to appease her was fix me up a room over the garage, that way I wasn’t technically living in their house I guess. And, if I had too much of my step-mom, I could get up and leave, go out to my room to get away.

The one thing I was happy about was my new little sister. She had just turned 18 and is a senior in high school, and was cute as hell, fun bubbly personality, and she and I had an instant crush on each other. She and I had a lot of fun together, she laughed when I tried to be funny, and defended me with her mom whenever she was nagging about me.

In the evenings we would all sit and watch TV before bed, my dad on one end of the couch with the step-mom snuggled up to him, me on the other end of the couch, and usually Lucy laying on the floor in front of the TV. When the late news ...

... would come on, that was when Lucy and her mom would get up and go get ready for bed, then come back in and say goodnight. Lucy would be wearing a long t-shirt and panties, her mom some frilly semi-transparent nightgown, she would hug and kiss her mom and my dad on the cheek, then hug me and go to bed. I would finish watching the news and then say goodnight and go off to my room over the garage, leaving my dad and his wife to whatever fooling around they would do before going to bed. I snuck out of my room one night and looked in the living room window, and saw my step-mom riding dad’s dick, with her nightgown up around her hips, dad’s face buried between her tits.

One thing my step-mom would get wound up about was when I would wear my cut-off shorts when we were all sitting watching TV. They were an old pair of sweat pants that I had outgrown, the legs being too short, so I cut them off and just wore them as shorts. I admit that I had cut them off pretty short, and if I sat in certain positions, the leg holes would gape open some and sometimes my balls could be seen, and if I got a hard on, it would be readily apparent. Knowing this pissed my step-mom off, I would purposely wear them when we were all watching TV before bed. She would complain to dad, he would just tell her not to look if it bothered her. Dad usually wore a pair of lounging pants to watch TV in, and one pair he liked had lost the button on the fly, and it would gape open sometimes, and you might get a glimpse ...
