(Relax. Everyone's over 18.)
Friday night, 11:30. My parents were out of town for the weekend. My sister Danica was out at a party. I was watching a horror movie on TV. Some psycho was slashing cheerleaders, all of them young and busty and frequently topless. I stroked my cock under my shorts as their boobs bounced, running away from the mad killer. Maybe I'd just find a porn movie--
The door opened, then slammed shut. "Hi, Trent!"
My sister Danica staggered into the living room. "Hi, Trent!" she shouted again. She was in a flimsy white blouse that weas unbuttoned almost to her waist, showing off her black bra. Her miniskirt barely reached the top of her thighs. "How ya doing?"
She plopped down on the couch next to me, kicked her high heels off, and leaned over to give me sloppy, drunken kiss. On the lips. "Whatcha doin'?"
"You're drunk." I turned the TV off. "And you're home early."
"Yeah, Susan caught me making out with her boyfriend and kicked me out." Danica laughed. "Bitch."
Danica was cute. Sexy, even. She had long legs, and she kept in shape with swimming and yoga. We didn't have a pool or anything, but anytime I saw her in a bikini at the beach or on vacation, I could see what other guys saw in her.
She was 23, in college, studying marketing--when she bothered to go to class. I'm 21, working on a degree in accounting. We've got an older sister, Madison, 29, but she doesn't live at home with our parents anymore.
I always kind of idolized Danica when I was younger. Even when she bullied me, I kind of enjoyed the attention. We were closer in age, and I could see she was pretty. She had lots of friends, stood up to mom and dad, and was really smart.
Now that we were adults, I could see that she wasn't always making the right decisions, and she was starting to coast through life on her body and her looks. I kept hoping she'd straighten herself out so she could get back to making good grades and doing something with her life. Instead she was drinking, smoking weed, barely going to class, and hanging out with the wrong kind of friends. Especially boyfriends.
Most of them were assholes. She had one boyfriend in high school who was a nice guy, but she dumped him after they graduated. After that she dated a bunch of different types, none of them for longer than a month or so. She didn't bring them home very often, but every once in a while she'd sneak someone into the house late at night, and I could hear them in her room. Groaning, moaning, slapping, laughing--and sometimes getting in screaming fights about God knows what, until my dad kicked the guy out and yelled at Danica all night, threatening to kick her out if she couldn't behave.
He never did, of course, and neither did she. Danica would calm down for a few weeks, then start the same old shenanigans again, trying to be more discreet this time, but usually making the same mistakes all over again.
At least she hadn't brought anyone home from the party tonight.
Danica leaned back and stretched her legs out. Her blouse was falling off, and I could see her boobs pushing at her bra. "Is there any beer?"
"I think you've had enough," I said.
"Oh, you're no fun. C'mon, get me a beer, would you?" She nudged my leg with her bare foot.
I groaned. "Fine." Maybe one more would put her to sleep--if she didn't throw up all over the sofa. I got one for her and another for me, and she snatched hers from my hands and guzzled half of it before I could sit down.
"So, whatcha doing?" She crossed her ankles.
"Watching a movie." I picked up the remote. "Got kicked out, huh?"
"Yeah. Stupid Susan." She laughed. "I was just making out with her boyfriend 'cause--" She stopped suddenly, looked at me, then looked away. "I was bored. And horny."
"Well, looks like you should have picked someone else. Now you're stuck with me."
"Yeah." She picked up her beer. I started the movie.
Danica reached behind her back, under her shirt, to unsnap her bra, like she wasn't thinking about it, and looked at the movie. A masked killer was watching a cheerleader get undressed, an axe in his hand.
"Yuck." Danica yawned. "You like this stuff?"
I shrugged. "You want me to change it?"
"No, this is fine." She picked up her beer again. "There are worse places to be, I guess."
Ten minutes and one dead cheerleader later, Danica was asleep. Snoring softly.
Her legs were up on the couch, and her short skirt smooth around her thighs. Her bra had slipped down, and I could see the edge of one nipple, her boobs rising and falling as she snored.
When the final cheerleader but one was dead, and the masked killer was defeated (or was he?), I turned off the TV. Danica was sound asleep on the sofa, one foot on the floor, her thighs wide enough for me to almost see her black panties.
I shook her knee. "Let's get you to bed, Dani."
Her eyes fluttered open. "Wha?"
"Bed." I stood up and reached for her hand. "Come on."
Danica giggled. "Okay. Take me to bed!" She got to her feet, leaving her blouse open, and grabbed my arm for balance. "Oh-kay." After a moment she took an unsteady step forward, and I followed her up the stairs and then down the hall to her room.
She opened the door and reached for the light switch, and lost her balance as the light came on. I grabbed at her arms to keep her from falling, and somehow the sleeve of her blouse slipped. She staggered as her blouse dangled from just one arm. I pushed her toward the bed, and she spun around to plop down on it, laughing.
I stared. By now her blouse was hanging from one wrist, and her bra dangled from her shoulder. Her tits were free, flushed and sweaty, and I couldn't help staring at them.
They were somehow bigger than I expected, even after seeing her in bikinis all my life. Small pink nipples. Her chest was flushed and sweaty, and her boobs bobbed up and down as she laughed at me for looking.
Against all my willpower, I felt my cock start to stiffen as I looked at her.
"What's the matter Tent? Never seen a girl's boobs before?" She spread her arms and leaned back, pushing her tits forward. "Take a good look! Here they are! You like them?"
I tore my eyes away and turned to the door. "Go to bed."
"Aw, you're no fun. Wait!" She stood up, yanking at her short skirt, then fell back down again. "Help me with this. I think something's stuck." She yanked at a zipper on the side.
I stood frozen. My dick was getting harder looking at her, half naked on the sheets of her unmade bed.
Danica was my sister. But fuck, she was hot.
"Well?" she glared at me. "Are you going to just stand there and drool?"
That snapped me back to attention, although it didn't do anything for my erection. I took a cautious step toward her, leaned down, and pulled at the zipper while she held the edge of the skirt. After two or three yanks, the zipper got free, and the skirt slid to her ankles.
Now my sister was sitting in front of me in just a pair of black panties, thin and sheer enough that I could have seen the outline of her pussy if I'd looked close. Instead I stepped back. "You're okay now. Go to bed."
She picked up the skirt and threw it into the corner. "Okay. Thanks. Good night, Trent." She looked up at me and grinned. "Gimme a good night kiss?"
"Uh, no." I waved a hand and left.
Back downstairs I cleaned up and locked the doors and turned off the lights. On the second floor again, I saw a dim light in Danica's room. Her door was half open. I went to check on her, in case she'd thrown up all over her bed or the floor.
Instead she was lying on the bed, on top of the sheets. Stark naked.
I stood in the doorway. I knew I should close the door and leave. Go back to my room. Jack off, maybe. My cock still felt hard as a rock. I knew it was twisted. But I couldn't bring myself to stop looking at her.
Her legs were long and tanned, still firm from tennis and gymnastics in high school. Her pussy was neatly shaved, with a short landing strip leading down to her slit, and her thighs were taut and sweaty.
Her boobs--I took a good look now that she couldn't see me. Round and firm, and almost as tan as her belly, which made me wonder if she was sunbathing naked somewhere. They kept rising and falling as she snored, her nipples pointing at the ceiling, hard and pink.
As I watched, my cock stiffer than ever, she yawned in her sleep, reached down, and scratched the inside of her thigh. Then, sighing, she flicked a finger across her pussy. Then she rubbed her nose, sneezed softly, and rolled onto her side, snoring louder.
Suddenly I couldn't take it anymore. Danica had been teasing me all night. She was my sister, and she was drunk, but I had to do something about the throbbing in my dick.
I yanked down my jeans and boxers and grabbed my cock. Staring at Danica's tits, I started stroking myself. My hand glided over my shaft, up and down, my blood pounding as I licked my lips, gazing at her nipples, then let my eyes wander downward to her pussy--her slit, her gash, her twat--which looked wet and warm, as if she was having a dirty dream of her own. Her legs twitched, and she slid a hand between her thighs as if her fingers were cold.
I rocked back and forth on my heels, grunting softly. I could feel the pressure building up inside me, my balls churning, my prick tensing. I bit my lip to keep from making any noise, but I couldn't help grunting softly as my cock throbbed harder and harder, looking at her all over.
Danica rolled over onto her back again, sighing in her sleep. Was she waking up? I couldn't stop if I wanted to, so I started pumping faster, breathing hard, fighting to keep my balance. Oh fuck, this was good, this was so good... my cock was already dripping, ready to explode. I looked at Danica's boobs, her pussy, then back to her tits again, her bare shoulders, her flat belly, her legs, her boobs, her pussy--
I came. I'd meant to spurt all over her body, but at the last minute I turned the head of my cock away and just let loose on the sheet next to her, shooting jets of sperm in a puddle of thick cum, over and over as Danica snored quietly and my brain rocked from the mixture of sights and sensations--my naked sister, my spurting cock, the cum pooling near her leg--I closed my eyes for a moment, and was afraid to open them, but when I did Danica was still asleep, clutching a pillow.
I finally stopped and caught my breath. Time to get out. Before I did, I grabbed a box of Puffs to mop up my cum. I got most of it, but there was still a damp spot on the bed, and I could sniff the faint odor as I put the tissue box back. Maybe it would fade away before morning.
I left, closing her door, and went back to my room. I didn't get to sleep for a long time.

Danica came downstairs at 12:30. I was still in the kitchen, drinking coffee and reading the paper. I'd slept late too. I was in a T-shirt and sweatpants, taking it easy.
She was wearing a sweatshirt and panties, barefoot and braless. Without a word she poured herself coffee and then sat down across from me.
I smiled. "Sleep well?"
