Alone I sat in my bedroom finishing up the final page of a report for my sophomore English class when a knock at our front door sparked my interest. I didn't have time to go out and explore, unfortunately. This was my very first assignment in my very first semester of college. I had tested out of all of my freshmen classes, so here I was, barely 18, and planning on finishing my degree before I turned 21. I had to stay focused, no matter how bored I was. When I heard the voices of my family and the mystery knocker I became even more eager to get out of this room.
The guest was Derrick, my sister's boyfriend. He was 23, tall, thin but muscular. He had dark hair, dark, dreamy eyes, and usually just the right amount of unshaven stubble on his face. I put my report to the side while I stripped off my clothes. I couldn't go out there in my loose long sleeve shirt and pajama pants. I needed something more appealing. I stood there in my panties looking around for something to wear, sliding my thumb just inside the waistband in anticipation. I suppose I'm a little short, about 5'2", and had a thin build, or what some would call petite. I loved this about myself because it made my ass and my C cup boobs really stand out. I had light brown hair that hung straightened and down past my shoulders. I grabbed a bra, a tighter-fitting, low-cut, short sleeve shirt and some loose short shorts and was satisfied as I checked myself out in the mirror.
I guess this would be a good time to mention my sister, Rebecca. She's a cunt. She's a top-notch bitch and always has been. She's rude and unpleasant to be around, and terrible to live with. She's even rude to our parents on a daily basis. She's been dating Derrick for six months now. In the beginning she was always sweet to him. She was caring and considerate, and to be honest it made the rest of us a little jealous, since she was never that way with us. Lately she hasn't been so kind to him, and sometimes downright mean. I give it another six months before she starts treating him like she does us. Hopefully for his sake, the spark will have died out by then and he'll be long gone. Oh, one more thing about my sister - she's gorgeous. She is absolutely beautiful. She is the only girl I know that I actually admit is hotter than me. She's got very light brown hair, almost blonde in the right light, and big green eyes. She's thin too, like me, with a great ass. I got the boobs in the family though, so that's one thing I have over her small B's. Sure it was wrong for me to be thinking of my sister's boyfriend like this. After all, he was hers and I didn't have my own. But none of that mattered to me as I exited my bedroom.
"Hey Derrick!" I said as I hugged and greeted him.
"Hey Lilly, good to see you."
"What are you up to?" I asked.
"Well, I was driving through y'all's part of town from my brother's house back to my apartment and I noticed it started to feel like I had a flat. I pulled over and sure enough there was a huge nail sticking into the tire," he explained.
"Oh no..." I said, with a cute and concerned face, my eyes fixed on him.
"Yeah," he continued, "so I stopped at the repair shop up the road and they had a line of cars. It could take a few minutes to get to mine or a few hours the guy said, which is unfortunate because I have some errands to run today. So I just was hoping to wait it out here. So you're mom invited me to go see a movie with them."
My mom and sister had made plans to go to the movies this morning. I was invited, but I really didn't have time. I had to get this report done, which sucked because now that Derrick was going, I wanted to go even more. But at least I would have the house to myself. My dad works every single day. He wouldn't be home until this evening.
"You sure you don't want to come?" my mom asked.
"I really have to get this report done. I'm gonna go shower and maybe perk up a little bit and then finish it."
"Suit yourself," Rebecca said.
I fake smiled and went to the bathroom. I started to undress. As they opened the front door to leave, I heard Derrick's phone ringing.
"Oh ok, well that sounds great then," I heard him say. "Ok thanks."
Derrick spoke again, this time to my sister and mom.
"That was the shop. They said they'll be getting to my car sooner than they thought."
I was intrigued and listened closer as I slid my panties off.
"So I guess y'all can drop me off at the shop if you don't mind and I'll wait there."
"It could still be hours. You could be waiting there forever," my sister said.
"Yeah she's right Derrick why don't you just come with us and get it later? Or you could wait here and have Lilly drive you to the place if they call before we get home," my mom told him.
"Well, she's got the report plus she doesn't even know I'm staying here I wouldn't want to-"
"Derrick it's fine it's two minutes down the street," my bitch sister interrupted. "We have to go I'll see you tonight."
"Bye Derrick," I heard my mom say as the front door shut.
So I was home alone with Derrick. I thought up a plan and hopped in the shower quick. The warm water on my skin, the thought of being alone with Derrick, the naughty plan I had - everything was making me jittery with anticipation. The touch of my own fingers on my skin was arousing me. As I washed my body, running my hands up each leg individually, then to my sides, then my ass, then between my ass cheeks, then up my stomach to my breasts - I was feeling so horny. I reached down and touched my pussy. I had shaved two days before, so there was only tiny little stubble. It was fine; I didn't have time to shave again.
I finished my shower and dried off. What I was about to do required me to work up some nerve. When I was completely dry, I wrapped my towel around my hair and prepared to step out of the bathroom. The way our house was situated, someone sitting on the sofa in the living room could easily see straight down the hallway. I heard the TV on, so I pretty much knew that Derrick would be sitting right there.
I reached for the knob and turned it. My sister's bedroom door at the end of the hall was open, and light from her window illuminated the would-be dark hallway. The air outside the bathroom felt so cool on my skin, I took a deep breath and stepped out. There I was crossing our hallway, completely naked with just a towel in my hair. I turned toward the living room and my eyes met Derrick's. His mouth hung open and my jaw dropped as well. I put my hands up to my mouth in a false show of embarrassment as he stared at my naked body. I stood there frozen, in a fake act of surprise and horror, for several seconds, giving him a show.
"Derrick I -"
