A week ago I moved back into my parent's basement, from my college dorm rooms. With this change in lifestyle, I realized two things: one, there are very few things in life that are more debilitating than living in your parents' basement and sharing a bathroom with your sister, and two, my sister had changed since I left for college.
When I left, she was finishing her junior year in high school and was two weeks from getting her cast off. She was a cheerleader, and had broken her leg when her bases failed to catch her during a routine trick. I'm proud to say that no, she wasn't the preppy blonde type that project enthusiasm from every orifice. My sister Katie was an brunette Irish girl with freckles under her eyes and a squinty smile.
But when I pulled my bottomed-out-with-college-shit-Honda into my parents' driveway last week Katie was the first to meet me. She threw the front door open and came bounding out through the front lawn to me. I couldn't hardly move; I was stunned. Her pale, thin legs had firmed and tanned. They were long and taught, all the way up to her green short shorts. She wore them the way she always did; with the waistband rolled down a few times to make them even shorter. Only this time I shamefully felt myself wishing she had rolled them one further.
To make matters worse she was wearing a tiny blue bikini top, her toned stomach and hips made up for her modestly sized chest. She had always joked about having a lack of boobs, but had sworn she was waiting for her ass to come in. When she crashed into me and threw her arms around my neck I found myself looking down to see if it had. I was not disappointed.
"Liam! I've missed you so much!" Katie said into my shoulder. I could smell lavender in her thick, brown hair.
"I know I'm sorry I didn't call as much as I said I would." I shrugged when she finally separated. She kept her hands on my shoulders though, her bright green eyes looking into mine earnestly.
"You think I actually believed you'd call every two weeks?" she glowered at me.
I laughed. "Well then I retract my apology, since I obviously didn't disappoint you."
Katie scoffed. "Jerk."
She insisted on helping me with my suitcase while I took my computer bag and backpack. I stayed behind a second to "lock my trunk" so Katie would walk in front of me. My mouth slackened at the sight of her ass in those shorts. They were so short that I could see just where the backs of her thighs curved outward to her ass. So tan. So smooth.
My parents - that is, Katie and I's dad, and our step-mom - greeted me from their various positions in the house.
"Hello, hello!" My dad called in his familiar echoing call from the dining room.
"Hello?" I called out, leaning through the entryway to see him.
He had his glasses low on his nose, looking down to his laptop on the dining room table.
"Hey, Liam. I'm in my office." Our step-mom Tracy said.
"Hey," I waved when she came into view behind her desk. She had lost weight, it seemed, but with her enormous tits hanging so low, it was hard to tell. But I could see it in her face. I didn't really care, Tracy was a bitch. I couldn't stand her.
"How was your drive?" Dad asked.
"Not bad. Little bit of construction in Pullman but nothing bad."
"Good, good. Well, your room's all cleaned out, Tracy took the storage boxes back out and put them in the boys' play room."
"Tommy and Eric are sacrificing their lego room?" I mocked astonishment.
"Yeah, big deal." My dad rolled his eyes. "Anyway, Katie said she'd help you unpack and Tracy and I are working on some numbers for a new client so we'll keep workin'."
"No problem." I nodded, unsurprised. Always the businessman, my father. Once I got too old for him to keep coaching he started to lose interest in making time for me. And when I football season was over senior year, and he couldn't even watch me anymore, it was like he couldn't have cared whether I was living or dying. Probably an exaggeration, but the point is still valid.
Anyway, Katie did help me unpack, making several trips out to my car with me to move everything in.
"I really appreciate the help." I assured her when the point of her being able to help had passed.
"No problem, dude." she smiled. "I'm glad you're back."
"Yeah, we'll see how long I last before I blow my brains out."
She laughed, a little too hard it seemed. Like she was exaggerating for my benefit or something. "Don't do that."
"Ok. Well, good night, and thanks again."
"Anytime." She left the room with a funny little strut that wiggled her big butt around and then she stopped and turned around at the door. "Are you going to shower before you go to bed?"
"Probably, yeah."
"Okay." she nodded, and then closed the door as she left for her room across the hall.
Looking around at my suitcases and bags of old dormroom knick-knacks and studying equipment, I realized I had a ton of work ahead of me, and I really didn't want to do it. Resolving to definitely do it tomorrow or never, I piled everything to one corner of my room, knowing I would be living out of that corner of living supplies until their containers were empty.
Instead I wanted to take that shower. I stripped down naked and threw a towel around my waist, and stopped to check myself out in the mirror by my door. I was relatively pleased, considering I had been so busy studying for finals that I had no chance to get any exercise. I was mostly just glad I had managed to avoid gaining the dreaded freshman 15. I knew a lot of people that even got hit by the uglier freshman 25. Sad souls, all of them.
I threw open my bedroom door only to find Katie halfway across the hall headed to the bathroom completely topless, and nothing but tiny pink Brazilian panties. She made no effort to cover herself, but merely made a slightly quicker step into the bathroom. She even kept eye contact with me, and I swear I saw a smirk on those red lips.
When she closed the door to the bathroom, I heard the shower head immediately burst to life. I couldn't help it; I was stunned again. She was so cavalier with her body in front of me suddenly. She used to be so nervous around me.
I suddenly felt a pulse of lust course through me and jolt my dick against my towel. I felt it lengthen and thicken as my thoughts of my sister in the shower suddenly turned very wicked. It took no stretch of an imagination to think of what she looked like completely naked; the panties didn't hide much.
Before I knew it I was leaning in the door frame, staring at the golden door knob of the bathroom with my hand under my towel, firmly squeezing my aching cock. I imagined the hot water of the shower cascading down her tight back and down her big round ass cheeks. She joked about getting her ass, and God knows she got one for the ages.
