My little sister and I were driving home from school, and I was in a pretty bad mood. It was bad enough that I was nineteen, and still in high school. And now it would be one more year of being jealous of all the other kids at school who had amazing plans for the upcoming spring break, which was only about a month away now. I was starting to realize that spring break of my senior year of high school was going to be another boring one. Our parents had never taken us anywhere fun, usually opting to leave me and my little sister home to fend for ourselves, while they went on a trip of their own. They had turned down my sister's idea of letting me and her fly to Florida alone together, and my sister hadn't stopped complaining in weeks.
We got home and I knew that only one thing could console me. I hung around in the kitchen as soon as we walked in, pretending to grab a snack, and my sister ran up to her room to change out of her uniform. At our school they wear classic schoolgirl uniforms with the little plaid skirts, long socks, and tight white tops. It's enough to drive a boy crazy. But my sister hated wearing them, and changed every day as soon as we got home.
I gave her a 30 second lead and then snuck up to my room. Our bedrooms shared a bathroom, and our closets also backed up to one another. Just last week, only a few days after my little sister's 18th birthday, I'd drilled a hole in the back of my closet to hang a hook back there, and realized the hole went right through her closet wall too. She hadn't been home at the time, so I went into her room to see how bad the damage was. The hole was just next to one of her closet shelves, hidden in darkness so that she'd never notice it. I was just thinking of patching it up, when I looked at her dirty clothes hamper at my knees. There was a tiny red thong just sitting there on top. I knew my sister often dressed like a slut, but it had never occurred to me that she wore thongs. I picked it up, and saw the wet spot on the crotch that covered practically the whole front of them. I was so turned on. I brought them to my nose and smelled her scent in, and the raw sweetness made my cock leap. I left the room before I got caught, but every day after that, my hormones would get the best of me and I just couldn't resist sneaking a peek as she got changed.
This afternoon was no different. I got into my closet and peeked through the hole. She already had her shirt and bra off, and was sitting on the chair by her desk wearing knee high white socks and pink panties. My sister had really small tits, and was quite skinny. Maybe almost too skinny. She certainly hadn't developed the more mature curves of other girls her age. She was the thinnest girl on the whole cheerleading squad, and with her braces, she still looked like she was sixteen. I couldn't believe she was actually eighteen now. She had a tight stomach and a perfect little ass framed by narrow hips. I could even see the little belly button ring that she had gotten just over a year ago on her seventeenth birthday. Normally I'd enjoy getting a hard-on while watching her briefly change clothes, or check herself out naked in the mirror. But today was something special!
She was already topless, and had her hand down her panties and was rubbing away at her clit. She was writhing around on a chair by her desk, her eyes closed as she frantically worked herself up. She bucked her hips back and forth across the pillow of the chair as she rubbed harder at her clit. Her panties were so sheer that I could just make out the lips of her pussy as she rocked, her breathing growing more ragged.
I hadn't masturbated in weeks, because of yet another promise to myself that I never would again, but this was just too much. I pulled out my dick which was already rigid and started stroking myself, trying to match her rhythm.
She rubbed her hand over her panties, pushing them into her pussy lips, and leaned back with her legs spread wide. Her arched back accentuated her narrow hips, and her little bright nipples were starting to tighten. She rubbed her hands along the insides of her legs and then reached up and started to pull her panties down. Her neatly trimmed snatch came into view. She had a short landing strip just above her clit, and the rest of her was shaved clean and smooth. The panties came completely off leaving her just wearing those damned knee high socks. I started to jerk away at my cock quicker than before.
Her hand dove back down to her pussy and she resumed rubbing aggressively at her clit with the flat of her hand. She bit her lips and I could make out the shiny wetness of her own juices dripping from her tight pussy and lubricating her flying fingers. She stopped playing with her clit as her fingers rubbed down between her labia, and I could see her hold back a gasp. She drove a finger into her pussy, and started to piston it in and out, a soft moan escaping just at that moment. She instinctively glanced back towards her door, probably wondering if I'd heard her. She added another finger, now pushing two of them as deep as they would go into her sopping hole. I could hear little grunts each time she thrust in, trying to get her fingers deeper than they were already going. She paused long enough to rub her clit a few times, rocking her hips again as she did, then resumed thrusting those two fingers deep inside her. Her moans were growing louder now, clearly audible through the thin walls of the closet.
She turned around with her legs straddling the chair back, and reached up her hands grasping the back of the chair and started to furiously buck her pussy hard against the loose pillow of the chair. Her legs were spread wide, straddling the chair, and her pussy had created a slick wet spot on the cushion and she was riding it back and forth, her clit rubbing against the wet spot on the cushion at the back of each thrust. She was bucking at the pillow so hard that it nearly detached from the chair, and she held it down with one hand almost desperately. The sight of her rocking hips and ass peeking out over and over was just fantastic. And to see her rubbing her nipples up against the chairback on each thrust was sinful. My little sister's body was phenomenal.
I turned away from the hole in the closet, disgusted with myself. What was I doing? What kind of pervert would spy on his own sister, let alone watch her masturbate and totally get off to her. I knew I had to stop doing this and stop fantasizing about her. I shoved my cock back into my pants. I paused as I turned to walk out of the closet when I heard a louder moan, and then the methodic rocking of the chair stopped. I went back to the hole in the closet to see what she was doing.
As I put my eye up to the hole, I could see her slowly rocking on the pillow. She must have orgasmed onto that lucky pillow, her juices dribbling down onto it as she came down from her high. She stood up and ran her hands across the slick spot on the pillow. She picked up the pillow off the chair and brought it up to her nose, inhaling deeply. I just saw her tongue dart out and taste at the wet spot, a smile forming on the corner of her lips.
She walked back to her bookcase, and pulled out an old encyclopedia. She opened the cover of what must have been a hollowed-out book and pulled out a long pink translucent dildo from inside. It was at least 9 inches long, and looked like a bunch of balls stacked one atop the other, each smaller than the one below it.
Almost without thinking she slid the dildo into her mouth, sliding it back and forth a few inches. I figured that my sister slept around, since she dated some pretty questionable guys. But I'd never imagined her giving a blowjob. So to see that pink rod slipping into her mouth was a thing of beauty. Her lips were still red from the day's lipstick, and her eyes closed as she bobbed the dildo back and forth into her mouth, now sitting on the edge of the chair.
I'd never had sex, let alone gotten a blowjob, so I couldn't even imagine what it would be like to have some girl do that to me. To grab the base of my dick and feed it into her mouth so tenderly, so carefully. As my sisters tongue slurped out and made circles on the tip of the dildo, I pulled my dick back out and resumed masturbating. She rubbed the dildo across one of her nipples, toying it briefly, before trailing the now-wet dildo down to her already wet pussy.
She slid the dildo slowly across her clit, each bump of the dildo pressing against her wet hole as it rubbed the length of her. She started to moan again, rubbing the hard rod back and forth slowly. She brought up one of her legs onto the chair, her toes pointed in those knee highs, and with her legs now spread I could see the cum from her previous orgasm had dripped down the inside of both her legs. Her pussy lips were spread wide and the dildo glistened as it continued to slide along her lips. She gripped it with both hands and with determination started sawing the dildo furiously across her labia and clit, gasping freely, her eyes still closed. Her body pressed towards the dildo as if begging it to slide up inside her.
She rocked back, and reached the dildo around behind her, and positioned the tip of it right at the entrance to her pussy. She was slower, more methodical this time, than she was with her fingers. I watched as each of those balls pressed up into the folds of her pussy; Watched as her lips slid along each ball as it entered her. Each ball was progressively larger in size, and by the time the dildo was buried half inside her I could see that she was straining to push it in. Damn, she must be tight. She slid the dildo out slowly, and then pressed it back in, more firmly this time. Over and over she sank it in, each time burying it more deeply inside her.
She stopped, pulling the dildo out and brought it up to her lips, her eyes opening. She looked at the cum dripping down it and slowly brought her tongue flat to the side of the dildo, and licked up it. She practically looked like she was licking a melting popsicle as she licked her own cum from the toy. I could see her working the flavor around in her mouth, and she dribbled her saliva back onto the waiting dildo.
She sat on the edge of the chair and brought one foot up tight against her ass, her legs spread wider than seemed possible. I silently thanked my mother for all those gymnastics lessons she'd made my sister endure, and the sight of her spread out, so ready, as she plunged that fake cock into herself made me let out a half-moan of my own as I hammered furiously at my cock, so close to cumming.
