I love my younger sister so much, I just didn’t realize how much I loved her since I got home from the military where we have precious “alone time”.
I just got discharged from the military and am on my way home. I’ve been away overseas for 4 years, that’s 4 years I haven’t seen my family, 4 years I haven’t felt the touch of a girl. It was mostly guys on my base, there were a few girls but it’s a big taboo to have sexual relations with your fellow soldiers. Besides I had someone waiting for me back home, she was my high school sweetheart, the most beautiful girl I know, it may be a total cliche but I proposed to her the day I left for basic training. And I wouldn’t be a real soldier if she didn’t break my fucking heart, a year ago she sent me a letter saying she’s breaking up with me, the time spent away from each other was too much for her. She said she found someone else. At least she had the decency to return the ring I gave her to my parents for me. In the end all girls are the same, just a bunch of whores, while I was away in the 110 degree desert she was getting her legs bent back by some fuck boy barista that I could destroy with one hand. My time in the marines had built up my 6’3 tall body to pack on 25 pounds of muscle. My fiancé probably racked up multiple bodies while I had my own body count which I won’t discuss any further as I’m barred from speaking about it, classified missions.
Anywho, waiting for me back home are my parents and my baby sister Ellie, last I saw her she just turned older and now she’s 18. My parents sent me pictures of her every month and it was so amazing to see her grow up into a gorgeous young girl. Ellie is very special, when she was in the womb there was another baby that didn’t make it. My mom is a small woman so both the babies were cramped tight and due to complications it led to a premature birth. Ellie was born just 5 pounds, she was in the NICU for months. As she grew up it became clear she wasn’t developing as a normal child would. She was always much smaller than everyone else in her class and had to be placed in special programs as she was diagnosed with autism. She was a heavy sleepwalker, every night she’d get up to roam around the house, she’d go to the bathroom and flush the toilet over and over, she’d open and close the closet door and she always always came to sleep in my bed, she loved me so much and felt safe with me. And no matter how hard we tried we could never snap her out of it, once she was going she wouldn’t stop until morning. And always she’d carry around her brown teddy bear I got for her for one of her birthdays. Ellie always called me “big brudder”. Looking at her you would never expect her to be “slow”, she looked like a normal cute girl just really small, such a shame really, I can’t imagine her ever having a normal dating life, either they wouldn’t be able to look past her mental impairments or the guys who would want to date her would have perverted reasons with how young she looks, even at 18 years old.
I just got off the plane and am walking to the waiting area. My parents are such goofballs, they were holding up a sign saying “JAMES HERE”. 4 years away and they think I forgot what they look like. When I saw them I almost lost it, I endured tremendous stress and terrible conditions abroad and didn’t cry once. But when I saw them I was so happy. As I was hugging them I noticed Ellie wasn’t there so I asked them “why isn’t Ellie here?” My mom exhaled as if she was exhausted and said “ohh you know Ellie, she hates car rides and wanted to stay in her room and color.” “How has she been lately? Is she okay?” I asked my mom hoping for good news. My mom closed her eyes and said “it was very tough on her when you first left.. she didn’t really understand you had to leave and would be gone so long.. every day she asked us where you were. But she knows you’re coming home and is very excited to see you”. Before I left and growing up I spent every day with her playing the big brother part playing with dolls, tea parties and TV. She loved watching TV with me, even if it was something only I liked watching she always sat on my lap and enjoyed spending time with me. Every day I was away I thought about Ellie, I missed her the most.
When we got home I didn’t even take my bags out of the car, I went right up to Ellie’s room so I could see her. Her door was open, she couldn’t see me but I saw her laying on her My Little Pony blanket coloring in her Hello Kitty book. I knocked on her door frame and sweetly spoke “hey Ellie”. I heard her gasp, she closed her book as she put it down revealing that beautiful little face of hers, eyes as big as the moon and blue as the ocean. “BIG BRUDDER!!!” She screams as she leaps off the bed and jumps soaring onto me wrapping her legs around my waist and hanging her arms on my neck. “Aww Ellie I missed you so much!!!” I said rocking her body side to side as her gorgeous silky blonde curls cover my face. As I held her she began to cry, I could feel her grip on me tighten as if she was an anaconda squeezing its prey before it swallows them. “Wahhhaaaahaa big brudder” she repeated as she cried some more. “Shhh shhh it’s okay honey, I’m here now okay. I’m not going anywhere” I said trying to soothe her cries and comfort her. “Do ya promise?” She asks me as she pulled her leaking face away from my shoulder looking up at me” leaving a big wet imprint of her face on my shirt. “I promise!” I said as I stuck my pinky finger out. She put up her tiny soft pinky and curled it around my larger, rough and calloused pinky.
She wouldn’t let me put her down for another 5 minutes, she was practically glued to me. Ellie was wearing some jean shorts and a sleeveless shirt. I was holding her up by her legs with my fingers slightly reaching over onto her ass and couldn't help but notice how soft and smooth her legs were, they sunk into my hands and body like jello, and her ass had grown nicely as well filling out to a lovely shape. With her so close to me I could also feel her budding A cup tits pressing into my chest. Finally I was able to set her down, she immediately gave me another hug this time with her feet planted on the floor. Ellie was always very short but it seems she grew slightly in my absence, she currently stands at 4’9. I sat on her bed with her with for a little with her sitting her ass right on my cock while she went back to coloring in her book. She kept humming a tune to the effect of “hm hm hm hmmm hm hm hm hmmm” over and over again. It made her whole body vibrate including her ass which rebounded onto my cock. Remember now, I haven’t felt the touch of a girls body in 4 years and little Ellie’s ass lay smack dab on my cock and her ass is very soft and squishy. Seeing her creamy smooth legs and feeling her ass like this started to make me hard. My cock is buried under and between her ass cheeks, it’s getting harder by the second, and still Ellie hums “hmm hmm hm hmmm hmmmm” making her ass vibrate, sink and spread further over my cock. My cock is harder than it’s ever been, I’m so deep in there I skipped the Mithril and went right to the Balrog of Moria. You’d gotta like lord of the rings to understand that reference so if you don’t I’m sorry. Point is her ass is fully engulfing my boner.
This is so wrong, I should get out of her right now, my little sister has unknowingly given me an erection and is massaging my cock.. but I can’t bring myself to get up.. this... this feels so fucking good! Don’t do it James, absolutely don’t do it. I said to myself trying to force myself to not touch her, yet I found my hand reaching out to touch her leg. “Hm hm hmm hmmm hmmmm” she keeps humming and her ass keeps singing while she keeps coloring. And then I felt it, my hand was fully placed on the top of her thigh, it was as if I had no control over my autonomy and operated solely on instinct. Ughh fuckkk her leg is so soft, so smooth and warm. I had completely forgotten what a girls leg feels like until now, and let me tell you it feels amazing. Okay James just keep your hand there for a second, get your fill and leave. No no James stop yourself. I couldn’t help but inch my hand closer to her inner thigh, the softest of skin on a girls body. Ohh fuckkk man what am I doing?? This is my little fucking autistic sister for crying out loud and I’m using her for my own sexual gratification. Fuck me she doesn’t even know what I’m doing, she just keeps coloring along and humming while my cock is sandwiched in her ass and my hand is squeezing her inner thigh. I need more, more!
I started thrusting my hips up and down making my cock slide between her unsuspecting ass cheeks, Ellie is humming and I’m humping. Oh my god yes, that’s it. I haven’t felt this pleasure in years. Then I go and stick my other hand on her other leg. I’m sitting on her bed with my back against the wall with my legs stretched out and Ellie is sitting directly on my lap, ass all over my cock and my hands are hooked around her little body with my hands dug into her thighs while I thrust my hips up and down, her head sits just below mine with her beautiful curly blonde hair right at my nose smelling her flowery sweetness. I go from gripping her soft silky thighs to moving my hands up and down from just below pussy to her knees, looking past her I can see her cute tiny bare feet flipping back and forth. Oh my god oh my god oh my fucking god this is incredible. I start thrusting faster making her body move up and down and still she doesn’t seem to notice, just more humming coloring. Ugh ugh ugh I moan.. am I really gonna go through with this? Am I about to use my little sister to make myself cum?? Fuck I guess so, trying to stop now would be an exercise of futility. Now I'm gripping onto her thighs so high up my thumbs are inside her shorts near her pussy, my other four fingers are moving back in forth in a gentle pinching motion. Oh fuck me here it comes.. my eyes are closed and I shake my head side to side in shame, this is so fucking wrong. And then I explode in my pants. My body is jerking as I thrust up higher and higher as if I’m getting more penetration. And still Ellie has no clue and says nothing. My cum is bursting out of my cock and filling up my pants. I can feel the hot sticky goo run down my legs into my ass. Fuuuuckkk that was amazing. After I stopped cumming reality set in, I 100 percent just molested my sister, I felt up her bare legs bordering on touching her pussy and used her ass to make myself cum. I can’t believe I just did that, that is not “big brudder” material. I was so ashamed of myself I lifted her up off me and went to my room disappointed. I couldn’t even look at Ellie at dinner, I could hardly even eat. I went out to my parents car gathered my things, unpacked and went to bed.
In the middle of the night I woke up to something crazy, so crazy I thought I must be dreaming. My cock was getting sucked and hooolyyyyy shit did it feel fucking good. I’m just laying there half asleep saying “ahh good girl, good girl” but I accidentally bit my tongue and it hurt. Wait a fucking second, if I was dreaming then I wouldn’t have felt pain. I’M NOT DREAMING THIS IS REAL. I flipped the blanket off me and it was Ellie.... Clutching her little teddy bear suckling on my cock like you would your thumb. Oh my god Ellie is sleepwalking... no she’s sleep sucking.. my cock....
