It was Friday night, about three o’clock. My sister Deanne had come home a minute ago, blind drunk again, as she often did lately. Right now, she was stumbling up the stairs in a fruitless attempt to make as little noise as possible to avoid waking up our parents. Of course, she didn’t need to worry about that, I doubt even a cannon blast would wake them. Not with his loud snoring and her earplugs. However, it did wake me.

In a few more moments Deanne would stumble into my room, she always did. My cock was already swelling in anticipation.

“Hi shexy” she slurred as she staggered through the door and steadied herself with both hands on my bed. I could smell beer on her breath, then taste it as she kissed me.
“I’m sho wet for you” she giggled and drew a slippery finger over my lips, “Here”.
The distinct aroma of aroused pussy entered my nose and I tasted the sweet tartness of her female nectar.

I could now see my sister’s naked pussy, neatly shaven and highly excited, below the hem of her little black dress. Deanne had already discarded her underwear, eager as she was for another drunk fuck with her brother. I made a mental note to look for it later, lest mom would find it somewhere and might start asking questions. My worrying was cut short, as seconds later the little dress fell on the floor and my sister was completely nude.

I knew what she wanted was wrong, but it was near impossible to resist my sister’s drunk advances, especially when she was crawling naked into my bed. I’m only human and Deanne was not just sweet, smart and funny, but unbelievably gorgeous as well. To top all that, she was a passionate lover and much better in bed than any of my girlfriends had ever been.
With every time we fucked, I regretted more that this perfect girl had to be my sister. If only she was another girl, any other girl. A girl I could take home and introduce to my parents as my girlfriend. A girl I could kiss in public and fuck while she was sober.

Not that I am complaining, mind you, and if there was any doubt in my mind, it quickly melted as she pulled down my underwear and closed her hand around my cock.
“It’s sho big” she cooed, gently jacking me off. “Ish it becaushe of me?”
Of course it was, but I wasn’t going to admit that to my drunk sister,
“Just suck it Deanne” I grunted.
She smiled at me and lowered her mouth over my cock.

A second later, her ruby red lips touched my pubes and a gagging sound confirmed that my cock was now deep in her throat. She continued to expertly suck my cock and fondle my balls for a wonderful couple of minutes. It wasn’t long before I felt the first signs of an imminent orgasm. I closed my eyes and tried to suppress the urge to cum, and enjoy my sister’s talented mouth as long as possible. Much too soon, I had to acknowledge the fact that it was impossible to hold off the inevitable any longer.

“I’m gonna cum!” I grunted to warn my sister I was about to flood her mouth.
I was surprised by her alertness, especially given her state of inebriation. Deanne spat out my cock at once and firmly squeezed its base of to prevent me from ejaculating all over her delicate face.
Once she was assured I wasn’t going to blow my load, she grabbed my cock again and swung her leg over my waist. She then guided my cock between her silky lips and sat down. Deanne’s pussy was incredibly wet and my cock smoothly penetrated her tight opening. My sister’s pussy swallowed my shaft until her labia kissed the fingers that still held my cock upright. Then she lifted her body again, high enough for me to slip out. Even in the dim moonlight I could see the creamy juice on my shaft, right up to the point where her fingers were.

Deanne stroked my slippery cock a few times, spreading her wetness along my shaft and mixing my precum with her own copious secretions. She rubbed the tip over her clit and ran it between the dainty lips, teasing me by letting the tip graze the entrance to her vagina and then raise her hips when I wanted to push in. Then she finally let the tip slip back into her hole, took her hand off my cock and dropped her ass all the way down. In one quick move she had taken every inch of me inside her smoldering wetness. She leaned slightly forward and placed her hands on my chest, then arched her back and began to sensually rock her hips. I could feel the little bump of her cervix rub against my glans and heard soft squishy noises from her pussy as she ground her swollen clit against my pubic bone.

While I couldn’t see much of her pussy as she was leaning forward, I had a great view of her firm breasts. I could just lay back and look at my sister’s bouncing breasts for hours. They were just the right size, still perky, yet perfectly round and full, and tipped with pink, rubbery nipples that were always hard and just begged to be fondled and kissed. I craned my neck to bring my mouth to the pink nubs when I suddenly became aware of my sister’s scent. She smelled great, a perfect blend of perfume, arousal and a touch of perspiration. I inhaled again, feeling almost light-headed.

She moaned softly and shut her eyes as I closed my lips around her nipple and gave it a little suck. She froze for a second and I felt a series of contractions race up and down her pussy. It was only a tiny orgasm, just prelude of what was to come later. Hungry for more, Deanne stopped rocking her hips and got on her knees. Then she took her hand from my chest and placed it behind her for support as she leaned back. Plunging her hips up and down, she began to fuck me with long, rapid strokes, effectively jacking me off with her pussy. The view of her jiggling breasts was replaced by an even more arousing sight of her hairless pussy and her moist pink labia swallowing my cock every time she plunged down.

As she rode my penis like a cowgirl, the fingers of her free hand worked frantically on her pussy, rubbing in little circles around her clit to coax as much pleasure from the little pink nub as possible. It never took much time for her to cum, and tonight was no exception. After only a minute or two, she lunged forward again and mashed her clit against my body as she fucked me with erratic, forceful jerks and thrusts. The first full-blown orgasm hit her hard and wracked her lithe athletic body. I could feel her pussy try to suck the sperm from my balls as she came, shaking and wailing like a banshee.
While I knew it was almost impossible to wake our parents, she was so loud, I began to worry about our neighbors. I pulled Deanne close to me and rolled her onto her back, pressing my lips against hers to muffle her screams while I furiously pumped my cock into her quivering body. Within a minute, her first orgasm was followed by a second, equally powerful orgasm.

I was close to cumming as well when Deanne climaxed again, and I kept thrusting into her as hard as I could. I was only seconds from exploding inside her when she froze and held her body tightly against mine. Her hands clawed at my back and her strong legs locked around my waist. I wasn’t able to move at all, locked in her grip as her muscles contracted uncontrollably for the duration of her orgasm.
Her churning pussy sucked and squeezed my cock as she kept cumming a really long time, moaning and panting into my open mouth. Then, as rigid as her body was before, she collapsed from pure pleasure overload. For a moment I was afraid she’d pass out before I had cum, but soon she stirred again. With her mouth back on mine, she kissed me while she slowly regained control of her senses.
“That was nice,” she smiled. “You’re a good brother”

Without letting my cock slip even an inch from its snug little hole, she rolled me on my back again and sat up again.
“Your turn” she said and began to bounce her ass up and down. The orgasm I was denied twice earlier was still close, but this time I wasn’t going to warn my sister. I just grabbed her ass and pulled her down even more forcefully while thrusting up at the same time, fucking her as deep as possible until I couldn’t postpone it any longer and flooded her pussy with a hot torrent of potent, incestuous cum.

Deanne kept rubbing her clit as I pumped an enormous load inside her, and just as I squeezed the last drops from my balls, she came again, shaking and panting. After another massive orgasm, she slumped forward, looking like she would pass out. I could feel my sister’s hot breath panting in my ear as she lay on top of me, shivering and convulsing for over a minute before she pulled herself up again.

“God, that was the best, ever!” she grinned and kissed me tenderly.
My hands wandered over her back and her firm, round ass, stroking her soft, sweaty skin as we kissed. Again I was sorry this minx was my own sister, but I was maybe equally sorry that she wouldn’t remember a thing tomorrow.
“It’s shtill hard” she said after a while, suddenly slurring again.

It was no surprise I was still erect, her pussy had been squeezing and sucking my cock throughout her lengthy orgasm and the snuggling afterward. As a matter of fact, I was almost ready for a second round. That was, if my sister was up for it too. To my delight, she was.

She dismounted my hips and got on her hands and knees with her ass up.
“Fuck mee from behind bruv, do me doggy shtyle”

I could hardly believe my luck; doggy style was also my favorite position, and fucking my sister this way was something I had dreamed of ever since she first crawled into my bed many Friday nights ago.
Years of yoga, aerobics and track running had given her an ass that was truly out of this world; firm, round and shaped like a beautiful inverted heart that flowed into a slim waist that was perfect for holding on to with both hands. To complement this wonderful work of nature were two little dimples at the base of her spine, something I found extremely sexy.
Right now, this gorgeous ass was pushed up high in the air, ready to be taken.

I don’t think my cock had ever been harder than when I got into position behind her. Deanne looked truly scrumptious. I grabbed her ass with both hand and pulled the silky globes apart. A thick, frothy glob of semen oozed from my sister’s rosy pussylips. I watched the creamy glob increase in size until it lost its battle with gravity and dribbled down her clit and onto the mattress where it pooled in a slimy puddle between her knees.

I aimed my cock at the gooey pink gash and thrust my hips forward, parting Deanne’s lips and slamming my cock deep in her pussy. In this position she was even tighter than before and I was also able to reach deeper as well, making her groan as I stretched her tissues with my cock. Of course her pussy was quite sloppy this second round, and I was glad for it. The reduced friction aided a lot in increasing my stamina and I fucked her savagely for a delightfully long time. Loud slapping sounds reverberated in my room as I slammed my hips against my sister’s ass, pressing her face deeper into my pillows with every thrust.

Soon Deanne’s muffled moans became louder again, indicating she was rapidly approaching another massive orgasm. I didn’t want my sister to cum and risk her passing out just yet. As I slowed down and eased up my thrusting to keep her from cumming too soon, I let my thumb roam over her tight little asshole. Deanne wasn’t likely to remember a thing anyway, so I felt safe to take more liberties with her than I would have done with a girlfriend. To my surprise, my sister seemed to approve of what I was doing, even pushing her ass back and up against my hand. Pressing a little harder, her puckered little hole slowly yielded and my thumb slipped inside her. I slowly moved it in and out a bit, while I kept fucking her pussy at an agonizingly slow pace.

I was just about to push a little deeper when she looked around and surprised me with another slurred request.
“Put your cock in my assh”
I could simply not believe my ears.
“what?” I gasped
“I want you to fuck me in the ass”

I was almost convinced I was dreaming as I pulled out of her creamy pussy and pressed the tip against the little hole. It was already loosened up a bit by my thumb, but still I had to press hard to open her up far enough to accept my cock. Deanne eagerly pushed back and tried to relax her muscles as much as she could. Suddenly the tight ring gave and my penis sank an inch or two inside her ass.

Deanne let out a yelp of pain as I invaded her rear entrance.
“Don’t…” she gasped and lay a hand against my hips.
I didn’t know whether to not pull out or to not push in, so I just held still. A few moments later my sister withdrew her hand again, giving me green light to push in a little more. I spat on my cock and slowly moved in and out, steadily fucking her deeper until my shaft was all the way inside her.

Nothing could have prepared me for the sight of her tight little asshole stretched around my cock, nor for the way the ring of muscles squeezed it like a rubber band. I don’t know if she ever had anal sex before, or if I was the first to fuck her ass, but my sister was the first for me, and I was simply stunned by the sensations of this incredibly tight hole.

I applied a little more saliva and sped up again. Soon I was fucking her ass almost as hard as I had fucked her pussy earlier and I felt my balls tighten again, in anticipation of an unprecedentedly intense orgasm. My sister was not far behind, and catching up fast. Every time I pushed in, I could feel her fingers tickling my balls as she was diddling her clit, laboring for another climax while I pumped her asshole. When she suddenly came, groaning and trembling over her entire body, her ass tightened so much, it was almost like it was trying to strangle my cock. For almost a minute, a series of contractions held me tightly and made it almost impossible to move inside her. With great force I pushed in one last time and shot my first rope of cum in her ass.
I kept cumming and cumming, pumping an enormous load in my sister’s bowels. I came so hard, I was light headed and my hands lost their grip on her waist. Stumbling over, I landed half on her back before I found new support on the mattress. On all fours now, I desperately kept thrusting my hips to squeeze every last drop of sperm into her.

Deanne wasn’t doing any better, exhausted from cumming, her arms gave way and together we tumbled on the mattress. There was no kissing or snuggling this time; Deanne was out cold. My cock slipped from her unconscious body and I rolled on my back, too tired to move. Deanne rolled on her side, her face on my shoulder and her arm across my chest, asleep in a drunken, well-fucked stupor. Again that wonderful scent of her entered my nose. For a moment I was tempted to just let her sleep in my bed, and maybe fool around a little more. But I wasn’t sure how she’d react in the morning, when she was sobered up a bit more. Then I thought of the risk of being caught spooning my sister by our parents and decided to take her to her own bed instead.
I put on a pair of pants and got her dressed as well as I could, then carried her to her room and laid her in bed. Kissing her one last time, I ticked her in and left. Tomorrow she’d wake up in her little black dress and probably feeling like she’s been fucked hard.

On my way back I picked up Deanne’s very damp thong. I briefly considered keeping the fragrant little piece of clothing, but decided it’d be best if I just made it disappear. After one last whiff, I buried it in the garbage bin and got back in bed.

The next morning Deanne looked like she had a terrible hangover when she appeared at breakfast. She didn’t show any sign of remembering our nightly romp, although she did blush a little when she saw me noticing her discomfort when she sat down at the table. Never did she show any affection towards me other than wholesome, sisterly love.
I felt really bad for taking advantage of her weaknesses and once again I resolved to resist her advances the next time she’d come to my bed, knowing full well I was incapable of doing so.

Such had become our routine: she’d come home wasted, we’d have the greatest sex I ever had, and the next day I’d feel guilty while she never remembered a thing. But after each time I was feeling worse and worse about myself. Finally I couldn’t take it anymore and delicately and with as much diplomacy as I could, I suggested she shouldn’t drink as much.

She laughed at me and told me not to worry about her. That night she fucked me with as much gusto as ever, sucking my cock back to life twice and letting me finish up her ass again. It seemed she was determined to give me the best night of sex ever, to make sure I’d think twice before asking her to stop drinking again.
It almost worked, if my selfish lust hadn’t been exceeded by my love and care for her. I just couldn’t enjoy this self-destructive habit of her. I had to try again.

I had learned the hard way that Deanne wouldn’t listen to me, so I decided I needed help to keep her from getting wasted again. The next Friday, I was going to enlist the help of her best friend Lynn. As usual she came to pick Deanne up around ten. I waited for my sister to go to the bathroom, so we’d be alone for a minute.
“Could I have a word with you?” I asked in a low voice.
Lynn briefly looked up from her phone. “Sure”
“I’m a bit worried about Deanne”
“Worried? What is it?” at least I got her full attention, and she stopped texting.
“Well, to be honest, her drinking”
“Her drinking?” she asked, a little confused.
“Could you, as her friend, keep an eye on her?”
“Sure, but why? I know she’s a bit peculiar, but her drinking is hardly a problem to anyone.” Lynn said, emphasizing ‘her drinking’ in a way that made me feel she wasn’t taking my worries seriously.
“Hardly a problem? She’ll kill herself if she keeps drinking like she does”

Deanne’s friend looked at me in amazement and was speechless for a minute.
“But… Deanne doesn’t drink!” Lynn said.

This conversation started to make less and less sense.
“Then how come she’s shit-faced every time you bring her home?” I asked, desperate for a little understanding.
“Shit-faced? Deanne drinks nothing but juice and water! She only takes one sip of beer before we go home. She can’t possibly get pissed from one little sip!”
“No… you can’t”

I was then that I realized the truth, and all the pieces fell together; Deanne’s alertness, her intermittent slurring… An act! My sister had been sober all the time, every time, it had all been a carefully constructed act!
Well, if she could act, so could I.
“Never mind what I said, Lynn… and please don’t tell Deanne we had this conversation”

Tonight I was going to call Deanne’s bluff, and then her ass would be mine. Always.
