The screech of breaks outside can only mean one thing: my sister Kelly is home from college. The baby of the family, Kelly surprised us all by choosing a college out of state, a big-ten school where, our mother worried, she would do too little studying and too much partying. I had done the same thing the year before, but, unlike me, Kelly had passed all her classes. Mom said she'd been offered an internship near school, but last I'd heard she turned it down. "Kelly wants to be home this summer," Mom said over dinner one night. "She didn't say why."
My sister Kelly had always been a fickle girl. One month, she was obsessed with musicals-the next, with mystery novels. It was like she was constantly trying on new personalities, new hobbies, trying to see which ones fit.
I hear Kelly's keys hit the table by the door. "I'm hooome!" she calls to no one in particular. Part of me wants to run down the stairs and see what a year at college had done to my nineteen-year-old sister-had she gained the freshman ten?-but I don't want to look like some eager puppy, running to meet her as soon as she got home. Kelly and I are close, but there's always been something weird between us.
If I'm being honest, I think the weirdness is my fault. I've never told anyone, but last year, something happened. It's hard to explain exactly what it was. The whole family was downstairs watching Chain Saw Killers 7, some cheesy movie the family had rented because everything else was out. After the first bloody chainsaw murder, mom shrieked and fled the basement. After the third murder, Dad yawned and said, "I don't think this one is for me. You kinds enjoy." By the sixth and seventh murders, Brad and Jennifer had declared the movie "lame" and "totally sick," and had ducked out of the den, too. Me and Kelly were left alone in the dark with Chain Saw Killers 7. Kelly was wearing a shirt that our mom hated-it dipped low in the front-and the fabric clung to Kelly's burgeoning breasts. I could see the straps of Kelly's bra through her shirt, and in the chilly basement den, I could see too her stiff nipples. It had been hot outside, but inside, Kelly was underdressed in her short summer skirt. I looked away, feeling like a creep for checking out my sister, but I couldn't help it-I was entirely hormonal. I felt a boner threatening my pants, and so I grabbed one of the sofa pillows and crossed my arms over it in my lap, trying to look bored.
As the chain saw killer approached victim number 8, Kelly gasped, eyes wide, and backed away from the TV from where she sat on the floor in front of it. She dropped down on the couch next to me. The killer raised his chain saw, and Kelly let out a little shriek, and then jumped into my lap, knocking the pillow out of place before I could stop her. "Kell, don't-" I said, my face turning red, but Kelly wrapped her arms around me shoulders, burying her face in my neck.
"I can't watch!" she said. Her breath against my neck made my dick jump. I held my breath; I knew she must have felt it. At that moment, I wanted to die. I waited for her to scream in real horror this time, to jump off my lap and call me a pervert, tell my friends what had happened, or worse, tell mom. Her body stiffened, and I waited for her to push me away.
I can never forget what happened next. Sometimes it feels like I made the whole thing up. Like it was wishful thinking.
Rather than jumping off my lap, Kelly breathed a sigh into my neck and resettled herself on my lap. I was wearing thin track pants, and her short skirt was no barrier between my hard dick and her panties. I knew she could feel how hard I was, and I kept expecting her to pull away, but she kept breathing into my neck, and pressing her cunt down onto my cock. I could feel the soft lips of her pussy against the twitching head of my dick. I wanted so bad to take one of those hard nipples in my mouth, but I was afraid of what was happening. Kelly tightened her grip on my back and I wrapped my arms around her back, my fingers resting on her bare skin just above her ass. She pressed down harder onto me and I couldn't stop myself-I lifted my hips slightly to press myself tighter to her. I could feel her warmth through her panties. My cock was as hard as it had ever been.
"I'm scared," Kelly whispered into my neck.
"Don't be," I told her. We were both pretending to be talking about the movie.
Her breathing was fast as she pushed down on me and I strained up at her. I could feel her heart pounding as she pressed her tits to my chest. My cock felt like it was about to burst; I hoped I wouldn't come in my pants right there.
Just then, Kelly let out a gasp of surprise. At first I thought I'd hurt her. Her grip around my neck tightened, then she shuddered and it loosened again. I recognized that, sitting on my cock, my sister had just had an orgasm.
Her body stiffened. Kelly cleared her throat. "Is it over?" she asked, still pretending to talk about the movie.
"Um, yeah," I said. "I'll let you know if there's another murder."
Kelly sat on the couch as far away from me as possible. She refused to meet my eyes. After about five minutes, she mumbled something about studying and ran upstairs.
I lived in fear that summer-in fear that I had hurt my sister without meaning to, in fear that Kelly would tell someone and I would be hospitalized for being a sick, sister-fucking perv. But she never did. We never talked about it again. Sometimes, I think I might have made it up, that it might have been just a fantasy, but I know it happened. When Kelly left the basement, I ran into the bathroom to ferociously jerk myself off. I came in seconds, into one of mom's hand towels. I know it sounds sick, but I've kept the towel. First I was too embarrassed to put it in the wash. Then, I don't know. It just kind of stayed in my closet.
I can hear Kelly walking up the stairs. I lean back in my desk chair, plant what I hope is a brotherly smile of welcome on my face.
"Mike!" Kelly is leaning in my doorway, beaming. Her shoulders and legs are long and tanned and hardly covered by short-shorts and a tank top that can barely contain her boobs. It's not like I've been taking notes, exactly, but her tits definitely look bigger. If there's an ounce of extra fat on her body, it's all in her tits.
I shake my head-cut it out, Mike. This is your little sister.
"Hey, Kell," I say. "Welcome home."
Kelly smiles warmly. "I'm so glad you're here."
"You mean you're so glad I dropped out of college? Damn, I'm glad someone is!" I joked.
Kelly laughed, tossing her blonde hair over her shoulder. "No, I mean I'm glad you're home this summer too. I learned a lot in college, and there's things I definitely want to talk about."
Stuff like sororities and bio lab, I'm sure. I give Kelly a polite nod.
"Where's Mom?" she asks.
"At the mall. She left some stuff in the fridge for us to heat up."
"Oh, good."
"Yeah, don't worry, Kell-I'm not going to try and cook anything."
"No, I mean-" Kelly looks down, embarrassed, then looks me straight in the eye. "I'm glad it's just us." Kelly walks slowly over to my office chair, until she's standing up right in front of me, looking down. Her tits loom over me and I hate myself, but I'm turned on. But I'm not immature anymore-I can play it cool now. I have any number of hot girls I can call up for a screw when I'm horny. No need to pop a woody over my little sister.
"Uh, do you want to sit down?" I ask her.
