Fucking my underdeveloped autistic sleepwalking sister part 2

I’ve abandoned my humanity in favor of fucking my baby sister. Once you step foot on the path there’s no leaving it.

I gotta be the worst brother ever, 4 years starved of female contact had forced my Neanderthalic deviance to reveal itself. What should have been a heartwarming reunion with my 4’9 autistic 18 year old sister turned into me taking advantage of her naivety, groping her little legs as I dry fucked her ass and came inside my pants. I was very conflicted, on one hand I know it was wrong, terribly wrong.. but god dam did it feel good, once that little rush of blood filled up my cock I couldn’t stop touching her until I had that sweet sexual release. I vowed to myself I’d never do anything like that again, I should be protecting her from sickos who would do such a thing and not be one.

It’s my first night sleeping in my bed, having spent 4 years sleeping on what felt like a rock at my military base, it made my bed feel like heavenly clouds. A sleep so majestic I was having a dream a girl was sucking my cock, it’s been years since I felt the warm wet mouth of a girl on my dick. Fuck this is a good dream, it feels so real. In my slumber I mumbled to myself “ahh good girl, good girl” but I accidentally bit my tongue causing which sprung me from my sleep making me realize that I was not sleeping or dreaming at all. I know for certain I’m wide awake yet I still feel my cock getting sucked. I flipped the blanket up and found Ellie laying beside me with my cock in her mouth. Whaaaattt the fuuuuckkk is going on??? I tried calling to Ellie in what can only be described a whisper scream like “ELLIE! ELLIE!” But she didn’t respond to me. Fuck I forgot she sleepwalks and comes into my bed when she’s done with her antics. Why the fuck is she sucking my dick tho?? She’s slept in my bed with me thousands of times and she’s never done anything like this. Is it because I sleep naked now? Something I picked up from my time at the desert base was sleeping naked, it’s so hot over there that wearing clothes to bed felt like a torture, if you wore clothes they’d get drenched in sweat and there’s nothing more uncomfortable than sleeping with damp fabric touching your body.

I could not get Ellie to wake up and stop, once she’s in her trance she does not snap out of it until the next morning. This can not be happening right now, I literally just promised I wouldn’t abuse Ellie ever again but here we are. Either the universe is rewarding me for my years of service to my country or I’m being punished for what I did to Ellie earlier. It feels like a reward, I mean a beautiful little girl is sucking my cock right now, doing an amazing job too but.. a part of me feels like my soul is tearing apart for molesting my sister and letting someone so innocent, so sweet and so pure suck my cock while they are in a vulnerable state and not put an end to it. Fuck me man, ahhh this feels so good tho. Ellie is suckling on my cock like a baby would a binky. She’s laying in her baby blue night gown in the opposite direction I lay in with her legs and feet at my head. Tightly under her arm is the teddy bear I got her for birthday before I shipped out. She has about 2.5 inches of my cock in her mouth tightly wrapping her lips around it creating an airtight seal. The suction in which she sucks is crazy, she has both sides of her cheeks and her tongue pressed hard against my dick. Why is this happening to me. I did try to get her to stop, I even tried lifting her head off me but she wouldn’t budge. Normally Ellie sleeps with her thumb in her mouth as a form of comfort but it seems she’s found something else to suck she likes better.

Seeing as I can’t stop her I decided to go all in on degeneracy and let her suck my cock, I mean it’s not like I’m forcing her to do this. If anything she’s forcing me to let her suck my cock, at least that’s how I rationalized it. *Suck suck suck suck* she goes. I’ve never had head this way before, the girl keeping her head still and almost swallowing my cock like you would when you have peanut butter stuck on the top your mouth and try to clear it out. Ah ah ah oh my god, oh my god this is incredible. Every few seconds I can feel her exhale out of her nose and tickles my balls. Fuck this I need to touch her again. I reach my trembling hand out and touch her barefoot, her foot is so tiny my hand dwarfs it. I gently massage her little foot sticking a finger in between each of her toes and after work my hand up to her calf feeling her soft delicate skin. I slightly caress her calf and travel up further to her thigh, ugh her thighs are delicious, but I still wanna go higher. My fingertips move along her thigh as if I’m playing the piano until wait.. she’s not wearing any panties under her gown?

I felt the bottom of her asscheek fold over her thigh and now my hand is fully grasping her bare ass. Gripping her ass I shake my hand side to side to give it the old jiggle test, her ass moved around like an Apache attack helicopter. *Suck suck suck suck* she’s still going on my cock, I can feel the pressure on the tip with how hard she’s sucking, like a starving vampire drawing blood from its first victim of the night. As Ellie’s sucking I’m gripping, I’m squeezing and I’m shaking that soft delicate sweet ass. Her gown was covering her ass and I wanted to see it so I used my other hand to move it up to see what I’m working with. Oh my god… I can see her pussy from this angle, the way she’s laying her pussy is in direct view to my face. Her little pussy is so tiny and so pretty and bald, not even a little stubble. Okay seeing as I already used her ass to make myself cum and she’s sucking my cock what’s the harm in me touching her pussy just a little.. with my finger that is….there’s absolutely no way I’m gonna touch it with my cock, I mean fucking my sisters pussy would be crazyyy and surely I wouldn’t do that… I graze my finger along the exterior of her magnificent pussy feeling the moisture like a cold perspiring glass of water…. But her wetness was hot and steaming like if you put your hand above a pot of boiling water.

I stick my finger tip inside her just barely so I didn’t rupture her hymen and move it up and down making Ellie moan ever so slightly as she *suck suck sucks*. Oh would you look at that, even when she’s sleepwalking she she’s just conscious enough to register pleasure, but not enough to wake up. I take my finger with her juices and bring it to my mouth and swish my tongue around it… woooo eeeeehh! That was invigorating, hit me like the first line of cocaine of the night. Okay, I decided I’m fucking my sister. Just as I was preparing to try to orient myself to do that I started to feel those tingles and jingles alerting me of my coming orgasm. No problem, I’ll just cum in her mouth and fuck her pussy after. Ellie’s sucking the tip of my cock so hard and good but it made me wanna go deeper into her mouth. *Suck suck suck* and I’m gonna blow any second. I’m still playing with her pussy with one hand moving my finger vigorously so I quickly use my other hand and push her head down until my cock enters her throat.

*Suck suck suck suck suck suck* like she’s trying to dissolve a jolly rancher in her mouth and BOOM. I start cumming into her tight little throat, she didn’t stop sucking at all. *Suck and swallow suck and swallow suck and swallow* guzzling my cum like a hungry puppy wanting mothers milk. Ohhhh my godddddd ughhhhh I’m cumming so fucking hard in my baby sisters stomach. I’m pushing her head down so far her nose is in my taint, I can feel her throat move up and down pushing down the cum. And still she’s *suck suck sucking* to the point it started to tickle and almost hurt, you know the feeling.. when you cum and she’s still sucking when it’s all sensitive. It became too much to handle so I had to use a little force to lift her off me.

Just as I finished cumming and got her off me I realized my door was open the whole time and at any point one of my parents could have walked by and saw their precious innocent daughter sucking big brudders cock. Okay I gotta be more careful about this, I’m gonna have to postpone the fuckening and be more methodical. As much as I’d love for her to suck my cock again it’d have to wait, now that my cock was soft and the adrenaline was gone I felt a slight pain from how hard she was sucking, I put my hand to my dick and felt it was swollen, over engorged with blood. My baby sister acted as both a blowjob machine and a dick pump. I got up to put some boxers on as a layer of protection so her mouth wouldn’t find my cock again and then I went back to sleep next to Ellie who in my absence put her thumb in her mouth, I guess she has an oral fixation. She looks so cute as she sleeps so peacefully, she looks even cuter knowing she’s got my cum swimming around in her stomach.

The next morning when I woke up Ellie was gone, back in her room I imagine. When I went to piss I looked down at my cock and saw it was purple. She sucked my cock so hard she turned it into one mega hickey. It looks like I fucked a pomegranate and slept with it on my cock. As I left the bathroom I saw Ellie outside waiting for me, below her mouth was a white crusty spot, some of my cum must have leaked out and dried over. Fuck I can’t let my parents see her like that. I licked my finger generously applying my spit and wiped her face to remove my lingering cum, she was smiling and said “hehe what are you doing big brudder?” In my head I said ‘oh just trying to not get disowned’. Ellie sucked my cock for I don’t even know how long last night and hasn’t the slightest clue, nor does she know what I plan on doing to her next time. It was very awkward at breakfast with my family, as I sat there eating my mom asked me “so did Ellie visit you last night?” I looked across the table seeing Ellie stick a fork into a sausage and bring it to her mouth seeing the tip go past her lips making me super nervous and defensively said “huh? No no.. I mean yea she did but I didn’t notice until morning” what a blatant lie. My mom getting all sappy said “you know she slept in your bed every night when you were away, she really did miss you so much”. Ellie with a mouthful of food chewing nodded her head and gleefully said “uh huh uh huh”.

Although I technically raped my sister, forgoing her purity I do wanna point out that I do love her. Just cuz she sucked my cock and swallowed my cum doesn’t mean I place any less value on her, in fact it’s the opposite. Later I asked Ellie if she wanted to walk to the park near our house and she was ecstatic. She changed into a pink sundress with spaghetti straps where the bottom is about 6 inches above her knees showing off her lovely legs. On the way to the park she grabbed my hand to hold as we walked. The bright sun and her pink dress made her fair skin radiate a beautiful glow, and with her blonde hair I said “Ellie you’re my little strawberry lemonade girl” she smiled biting her bottom lip and started skipping. She wanted to go on the swing and said “push me big brudder!” I’m standing behind her as I touch her shoulders and moving my hands down her slender arms and grab her waist feeling her petite body for a few seconds, oh man her body is amazing. Each time I pushed her she kept saying “yayy”. A few minutes later she asked me “push me higher” she’s such a sweetheart, I’m rotten for wishing she would ask me “fuck me harder” instead.

After the swings we went and sat on the bench overlooking a pond where geese were swimming. I looked around to see if anybody else was around and we were all alone. In a calm and inviting voice I said “why don’t you sit on my lap hunny bunny” Ellie playfully says “hehe okayy” and then proceeded to get up and sit her ass on my cock. Oh fuck her ass is even more soft and squishy with her thin dress. My cock sunk into her ass like a hot knife in butter. I checked the area again to make sure nobody was around to see us, seeing the coast was clear I placed my hands on her knees. Every couple seconds I moved my hands back higher up on her legs seeing if she’d say or do anything but she didn’t, she’s too fixated on the geese in the pond. Eventually I had my hands dug into the insides of her thighs making Ellie say “oooohhhh”. I asked her “what’s wrong baby?” And she replied “mm that feels goood”. Fuckkkk Ellie likes me touching her like this, my cock started to get real hard. Ellie took notice of my erection and said “what’s that?” I tried playing it off and asked her what she meant and then she moved her body back and forth grinding her ass along my cock and said “that hard thing on my bum.. what is it?” I still had my hands in her legs slightly tickling her making her moan and said “oohh that’s just my phone”. She moved her ass back and forth a couple more times making making my eyes roll back into my head and she said all cute “hehe you got a big phone”. And just then I saw some people heading our way so I had her get up off me. James what the fuck are you doing? Were you really about to use your sisters ass to get off again in a public place? Think damnit.

Phew that was close, Ellie may be 18 but she definitely doesn’t look like it. I can’t even imagine what a passerby would think, say or do if they saw a young 4’9 girl in a dress rubbing her ass over the lap of a 6’3 tall guy in a park.. but I know it wouldn’t be good. Later on after dinner Ellie and I cuddled on the couch watching tv like old times. I restrained myself from touching her the whole time, I was afraid that I wouldn’t be able to stop and I’d outright rape her while she’s awake. I love my sister to death and I couldn’t put her through that. I’m still gonna fuck her but just when she’s “sleeping”, I still get the satisfaction of wearing her pussy as a cock hat and she doesn’t ever have to know. Call that a win win. It’s 930pm, the time Ellie goes to bed. I was sitting on the couch with the recliner up and Ellie was sitting right beside me. She turns to me and says “I’m gonna go night night now okay” I say back “okay ya little brat goodnight”. Before she got up climbed on top of me straddling me and hugged me tight and whispered “I love you so much big brudder, I’m so happy you’re home”. Dam what a shot to the heart, the things I’ve done to her.. and the things I’m gonna do to her. She deserves a better brother, someone who wouldn’t use her ass as a sex toy, someone who wouldn’t feel her body up like a sick and twisted masseuse, someone who wouldn’t allow their sister to suck their cock and swallow their cum, someone who’s not planning to fuck her and steal her virginity when in such a helpless state of unconsciousness. I was that brother once before.. but I guess war changes a guy. I hugged her back softly rubbing my hand along her back, not in a sexual way but more in a way you hug someone when you’re trying to console them. “I love you Ellie, I’m glad to be back home with you too” I said feeling my heart split in 2.

I’m sitting on my bed waiting for Ellie to come into my room, my door is slightly open and I’m looking out into the hallway. She has to pass my room to go to the bathroom, that’s the first thing she does when she’s sleepwalking, she goes and flushes the toilet a bunch and then opens and closes a specifc closet door as if she’s possessed. Then she’ll come to my room and get into my bed. It’s just past midnight and I saw her walk by my door, it’s begun. 30 minutes later she comes into my room. I sprung up from my bed and went to close and lock my door, what happens next is between me and Ellie. After I shut the door I took off my shirt and boxers and laid down next to Ellie naked. Ellie was wearing a white satin night gown.

She was sucking her thumb, I slowly pulled her thumb out of her mouth and put my soft cock to her lips. She wasn’t taking the bait so I pressed her face and lips closer to my cock and I felt her open her little mouth and started sucking the first inch of my cock. Ahh fuck there it is, oh man that feels good. My cock was blowing up like a balloon expanding into her mouth. I have about 3 inches in her mouth. *Suck suck suckkkk* fuckkk. She sucks real hard and I don’t want her doing it for too long making it go from purple to black so I’m gonna expedite things. Before I fuck her I do wanna eat her little pussy tho. As shes sucking me I’m repay her in kind. I pull her by her waist lifting her on top of me in a 69 position. I push her night gown back lifting the veil to reveal her pussy. What a fucking beautiful pussy she has oh my. I place my hands on her ass cheeks and lean my head in. I daringly stick my tongue out and lick her pussy from bottom to top and heard a quiet “mmm” over my cock. I do flat tongue licks covering her entire pussy, she taste so good.

Ellie keeps *suck suck sucking* and I’m *lick lick licking*. My cock is in my sister mouth and Ellie has her brothers tongue in her pussy. I jam my tongue in her pussy a few times and cycle it with focus firing on her little clit. I can taste her getting wetter, I can hear her moaning louder. As her unconscious moans intensified she stopped sucking for a moment going “mm mm mmmmm” with my cock in her mouth and started to have her very first orgasm. As I lick and probe her delicate forbidden budding flower it’s dripping with dew, I swallow her delectable nectar coating my mouth and throat in a velvety gloss. It has notes of both sweet and savory with an aftertaste of innocence. Oh sister, sister sister sisterrr I love you. Okay it’s time, enough of the foreplay and appetizers I want the main course. I lifted her head off my cock and put her on her back. I grabbed the bottom of her nightgown and pulled it up and over her head so she was naked from head to toe. This is the first time ever I’m seeing her naked body. Ellie’s body is a work of art, she looks as if she was forged by the Greek smith god Hephaestus.

Okay James you can do this, you’ve had sex plenty of times before so you can do it now. Ellie may be your sister and unconscious but pussy is still pussy, you just gotta put your cock in it don’t over think it. I get on top of her between her legs pinning them back with my arms. My cock is inches away from her holiest of holes, it’s not too late to stop.. I can just get off and not do this. I found myself getting closer and closer. My cock is now touching her pussy, oh fuck man I can feel her hot juice on the tip of my cock. Jamesss it’s still not too late, you can totally stop. Don’t fuck your sister don’t fuck your sister. My hips started moving on their own, I thrusted in tore her hymen open. Oh fuck oh fuck I’m fucking my sister, I’m fucking my sister ah ah ahh. Fuck her pussy is so tight and wet. I feel pressure trying to keep me out and her wetness letting me go in. Ooooohhhh my goddddd, Ellie’s pussy is fucking magical. I fucked 10 girls before Ellie and never ever have I ever felt a pussy like this one. Each time I thrust my cock into her pussy her legs clap against my arms. I can see her head jerk back and forth each thrust, I have like 100 pounds on Ellie and there’s a lot of force from my body colliding with hers. When my cock goes into her pussy she lets out a little whimper like *thrust* “mmmmh” *thrust* “mmmmmh” over and over and over.

Here I was last night thinking Ellie’s mouth was tightest thing my cock has found its way in but her pussy makes her mouth look and feel like the Grand fucking Canyon in comparison. I started pulling my cock out all the way and thrusting back in, she was so wet it didn’t matter what part of her pussy I hit on the way back in, her pussy gobbled up my cock like a Hoover deluxe. Full thrust out and then full thrust back in. It was amazing feeling her pussy open up to the exact width of my cock. 10 pull out all the ways and thrusts back in Ellie queefed… I thrusted in andddd “fraaaapppp” oh my goddd was it loud. I must have been pushing too much air in her pussy and it forced its way out when my cock displaced it. Upon her queefe Ellie let out a massive moan, her vibrating pussy must have felt real good, it certainly felt good on my cock.. no wonder why girls like vibrating dildos.

After that I pulled my arms out letting her legs drop to the bed placing my full body weight onto her and started fucking her harder. I got my hands and arms gripped onto her head using it as leverage to pull myself into her. I can actually hear her pussy getting fucked with how wet she is, it sounds like I’m mixing in a bunch of butter into a bowl of mashed potatoes. *Schluck schluck schluck* is the sound her pussy makes from my 6.5 girthy cock surpassing her labia, scraping against her slimy uterine walls and hitting her cervix. Oh fuck!!! This pussy is just so goodddd. Each thrust makes her little legs sway back and forth, feet dangle and she moans into my chest. Mmmmfuck sister.. thank you for this welcome home present, big brudder loves you dearly. *Thrust ahh thrust ahhh thrusttt AHHHH*.

My breaths started to deepen, I’m taking in more air than someone with emphysema on oxygen. Wait a minute, what am I gonna do when I need to cum? I’ve been fucking my sister rawdawg this entire time. In my dark desire to fuck her it didn’t even occur to me to slip on a condom. *Thrust schluck thrust schluck*. Oh Ellie, oooohh Ellie! I moved one of my hands where my palm was on her face and my thumb is across her lips. I felt her mouth open and tried to suck my thumb. Ooohh Ellie wants to suck something huh. I jam my thumb into her mouth on her tongue and she starts suckling my thumb like a tootsie roll. I got my cock in her pussy and my thumb in her mouth. This is the greatest night of my life.

Im overstimulated, I’ve lost all cognitive abilities and operate solely on instinct. Oh fuck oh fuck I’m about to cum.. where do I cum? James don’t you dare cum in your sister, don’t you fucking dare! I know I know I shouldn’t cum in her pussy. *Thrust thrust thrust* oh fuck it’s coming, it’s coming! Ahh pussy, pussy pussy pussy. I know I should pull out, I told myself I was gonna pull out but.. *thrust thrust thrusttt* and fuck meeee I’m cumming inside my sister fucking pussy. Oh my god oh my god ahhh I’m cumming inside my sisters pussy fuckkkk. I was mostly silent the whole time I was fucking Ellie too until I started to cum. As I was filling her pussy up with big brudders seed I was moaning loudly “OH OH OHHHH” like some perverted reverse Santa. Instead of giving her toys wrapped in paper I was giving her hot thick cum in her pussy. I was cumming so much and my cock throbbed so hard it was pulsating my cum out of her pussy, running down her asshole onto the bed. I laid on top of my sister between her precious legs, cock in her pussy, cum gushing out, I couldn’t move a muscle. I felt a bliss unlike anything I ever felt, a full body orgasm that transcended space and time. In the blink of an eye I saw flashes of my sister growing up into the girl she is now.

I kissed her on her softly supple lips feeling them move to my lips movement, almost as if she was kissing me back. I’d like to think she was subconsciously thanking me for fucking and cumming inside her. Certainly made me feel better about what I’ve done. I slowly pulled out of her and laid beside her. My hand was on her chest feeling her tits, tracing around her nipples as they got hard. I ventured down to her pussy to feel the creampie and holy molyyy. Her pussy is overflowing with cum, it’s gonna be in there for days. Of course I cleaned her up afterwards, got a face cloth and wiped up what I could and then redressed her. I certainly can’t have her wake up naked with a pussy full of cum now. Once she was cleaned up and dressed I laid with her cuddling her like she’s my girlfriend. I was joyful listening to her breath and was thankful she’s my sister.

I just had an epiphany, Ellie comes to my room every night and stays here until morning. I can fuck and cum inside her every night. This is gonna be dangeroous.
