My GF's Little Sis/Story

My Girlfriend's Little Sis

I’ve done a lot in my twenty two years. Some things I’m not proud of. But nothing compares to what I did to my girlfriend’s sister last spring. I had never told anyone, but I was secretly a pedophile. Adult women were attractive to me yes, but it was little between the ages of eight and twelve that really got me excited. Naturally I kept this a secret from my girlfriend Kate, as she would break up with me if she ever found out. Kate and I had been dating since sophomore year in college and I love her deeply. However, I secretly find her little sister Sarah to be irresistibly sexy.

One summer, I was alone in Kate’s house. She was off running some errands while I stayed behind to help out with her chores while little nine year old Sarah was outside playing. I took the clothes hamper and and collected dirty laundry to go in the wash. I went into Sarah’s room and saw quite a mess of clothes strewn about the flood. I guess nine year olds just aren’t very studious about cleaning their rooms. While gathering her clothes, a particular garment caught my eye: a pair of cotton panties with pink and white horizontal stripes, and a blue ribbon bow above the crotch. To a pedo like me, this was a sight to behold. I had always had sexual fantasies about Sarah, but was extremely cautious not to get into any trouble. I picked up the panties and just couldn’t bring myself to throw them in the hamper. They were just too tempting.

Instantly, my lust overcame my better judgment and I began to masturbate with her panties. I rubbed the soft cotton panties along my erect shaft, savoring each stroke knowing that these panties had hugged Sarah’s delicate flower. I began rubbing ever more vigorously as I neared my climax. Just before I went over the edge, Sarah opened her bedroom door and caught me red handed. It was too late to hold in my lust. I shot a thick rope of cum all over the elementary school girl’s bed sheets. “Oh my God Jack!” She shrieked “What are you doing with my underwear!? And did you just pee on my bed?” Too shocked to say anything, I dropped her panties and jolted out of her room with my tail between my legs (or was it my boner?) terrified of the consequences I would surely face once she told her parents. At best, my relationship with Kate was over. At worst, I would be arrested and have to register as a sex offender. I went home and waited in anguish.

Shockingly, she never said a word to anyone. As the weeks went by, I kept anxiously dreading Sarah spilling the beans to her someone, thinking that my life as I knew it could end any minute, but my anxiety waned as time passed and I appeared to have avoided any consequences for my perverse actions.

Two years passed, and Sarah was now in the 5th grade. I hoped she had forgotten about my unforgivable violation of her innocence just two years prior. I didn’t dare attempt any further mischief with her knowing the risks. That’s not to say the temptation had subsided. She had truly blossomed into a gorgeous eleven year old. He hips grew curvier giving her an hourglass like figure, and her little titties had just started to sprout, but still remained small and girlish. If anything, she had grown even more attractive to me.

I was at Kate and Sarah’s house yet again. This time I happened to be alone with Sarah. Kate was out having a girl’s day with her friends and we had been looking after Sarah while her parents were on vacation that week. I walked through the screen door out to the back yard. “Hi Sarah” I waved. She was tending to the garden, on her hands and knees with a trowel in her right hand and watering can beside her. She was wearing short denim overalls with a pink cotton T-shirt, a sunhat, and high white socks with black Mary-Jane shoes. Her tantalizing denim-clade behind was on display. Looking over her shoulder she replied “oh hi Jack”. She seemed preoccupied with a patch of white daisies growing in a flower bed. “I just love gardening, don’t you? It’s one of my favorite hobbies.” in reply, I said “It’s not my cup of tea to be honest, although I certainly see the appeal.” She turned back to her daisies. “I suppose it isn’t for everyone.” she said. She began humming and swaying her hips side to side rhythmically, almost as if trying to seduce me. “You know what? I think these daisies would look good inside on the kitchen table, wait here, while I go get a vase.” She walked past me and went back inside the house.

I waited for about five minutes and she had yet to return. I decided to go inside and check on her. I slid the screen door open and noticed something peculiar. Sarah’s overalls were laying on the ground in the middle of the living room. “That’s weird” I thought. I walked further into the hallway and spotted the pink T-shirt she had been wearing outside laying on floor as well. Why would she leave her clothed haphazardly strewn about the floor? Unless…

No, ridiculous, there’s no way my girlfriend’s eleven year old sister is trying to seduce me. Or is she? I approached her the entrance to her room and looked down. Laid bare on the floor were a pair of pink and white striped panties with a blue bow on top. The very same pair that I had masturbated with when Sarah was in 3rd grade. My heart sank as I contemplated the scenario I was in. I cautiously knocked on the door. “Sarah, are you in there?” I inquired. “come on in!” she said. “I have a little surprise for you.

I opened the door to her room, and as I gazed in I couldn’t believe the site before my eyes. Sarah was laying on her side on the bed seductively, completely nude except for her white thigh high socks. Her head resting in her left hand while she held the daisies she had picked in her right, using them to cover her little pussy. “You didn’t think that I had forgotten about the pervy things you did in my room when I was in 3rd grade did you? I’ve learned a lot about sex since then”.

I nearly lost it. She remembered everything, and she left that trail of clothes for me to follow because she was in fact trying to seduce me! I took a big gulp and began to speak. “listen Sarah, what I did then was wrong. Very wrong! I can’t do anything further with you or I could go to prison.” I said sternly. “You think I don’t know that?” she retorted. “You're in no place to lecture me right now. I could tell my parents about what happened two years ago and your life would be over.” I knew at that point that she had me by the balls (though only figuratively at that point). I had to tread extremely carefully or I was doomed. “what will it take to buy your silence?” I asked. “Oh I think you know exactly what I want, and lucky you, I’m going to give you what you want. You just have to be honest with me. Her gaze drifted down to he privates. The daisy petals were large enough to cover everything. I still wasn’t sure if she had grown pubic hair or not. She was at that age where a girl’s first hairs typically appear. I really hoped she hadn’t as bald kiddie pussies are a huge turn on for me. “do you want me to move them out of the way?” she cooed in a teasing baby voice. Shaking with anticipation, I timidly nodded, unable to resist the allure of her little preteen cunny. “Alright, then repeat after me” she said.

“I’m a sick, dirty pedophile, and I want to fuck my girlfriend’s prepubescent little sister and cum in her tight, slippery, loli pussy.”

Damn, she really wasn’t beating around the bush (I really hoped that she didn’t have a bush yet). Sweating and shaking, I replied,

“I’m a sick, dirty pedophile, and I want to fuck my girlfriend’s prepubescent little sister and cum in her tight, slippery, loli pussy.”

“Good! Now that you’re being honest with me, I think you deserve a reward.” She moved the daisies above her head to reveal the most tantalizing completely hairless slit I had ever seen. It was perfect; two plump, completely smooth labia snuggled up to each other and not even a hint of peach fuzz. It was a flawless rounded W shape with a valley in between her lips. It looked pristine and untouched; I couldn’t see any of her obscured pink insides. My jaw dropped at the sight her perfect hairless vulva.

“look at you, panting like a dog. Do you want to see more you sick pedo? Well here you go!” She took her right thumb and index finger and spread her labia majora apart, revealing her entire vulva. Her insides were bright pink. Her hooded clit was tiny, yet plump, like a delectable juicy berry waiting to be picked and savored. Her vagina glistened with slippery secretions. Despite her youth, her sex looked gooey wet, and prepared to gobble up cock.

“Here’s how this is going to work. You’re going to give me cunnilingus until I’m satisfied, after which I’ll give you fellatio. Then we’ll have vaginal intercourse. Don’t worry about ejaculating inside me. I haven’t started menstruating yet.” She used proper anatomical terms like a precocious child who had just learned about them from a sex-ed book. That probably was the case. She likely didn’t even know about less formal terms like “eating out”, “blowjob”, or “cum”.

“Ok” I replied. “But you can’t tell anyone about this. If you tell a single living soul about this, I’ll go to prison for sure.” Sarah grinned with delight. “Then it’s a deal. Now show me what you’ve been giving my big sis!” She spread her legs, clearly indicating that she wanted me to get to work. I took my shirt and pants off and got down on the bed with her. I wrapped my upper lips around her lower ones and began to suck.

“Oh Jack!” She moaned. “I had no idea it would feel this good. My sister has been greedy hogging you all to herself.” Ignoring the praise, I continued eating her out. As I gave her slit a good lick, I moved my attention to her little love button. I gave he clit a good strong suck. “Oh Fuck!” she cried out in ecstasy. I pivoted from sucking to swishing my tongue back and forth rapidly across her clit. “Oh Fuck, Oh Fuck, oh Fuck!” she kept crying. “I’m going to cu-c-c-cuu… ohhhhhh!” she roared. I could feel her pussy juice drip onto my chin as she reveled in her satisfying orgasm. She spent a minute or two recovering her senses from her climax. “I should have made you do that a long time ago. It’s so much better than rubbing myself.” “I’m glad you liked it” I still wasn’t quite sure what to say as I still hadn’t internalized the fact that I was having sex with a 5th grader half my age, and not just any 5th grader but my girlfriend’s sister. “Get on you back.” Sarah ordered. “You’ve earned this.”

I wasn’t sure how well Sarah could give me head considering her youth an inexperience, but I didn’t really have a choice in the matter. I had already come this far, I might as well enjoy it. I laid down on my back and removed my boxer briefs. My erection was as hard as diamond. She grabbed the base of my shaft with the other as she moved her mouth over my glans. She couldn’t take very much in considering the size of her mouth, but her technique was impressive nonetheless. My dick twitched with each stroke of her tongue. “How do you know how to do this already?” I inquired. “My parents don’t know how to block adult sites on our WiFi network, so I watch a lot of porn” she explained. I was curious why she didn’t use slang terms like “blowjob” earlier if she had already watched porn. I guess kids were just kind of weird and unsure what to say when it comes to sex. My curiosity quickly subsided and was replaced by lust as she sucked my cock. As she bobbed her head up and down with her lips tightly kissing my cock, I shivered with excitement. Just as I was about to cum, she stopped.

“I don’t want you cumming before the main event Jackie boy. I want your nut in my pussy, not my mouth.” she said as she got up and began straddling my cock. “don’t worry, I can take you” she boasted, sliding her slit up and down along my now slick shaft. “I may be young and a virgin, but vaginas are flexible and I’ve been practicing with my big sis’ dildo. I might not be able to fit your full length, but I can definitely fit your girth.” Astonished as I was that she had already inserted a dildo before, It was a little difficult to process that while she raised her hips into position so that her opening was resting above the tip of my cock. “Holy Shit!” I thought. I’m actually going to have unprotected vaginal sex with my girlfriend’s elementary school aged little sister.

“Are you ready to feel the bliss of little girl pussy you dirty pedo” she teased? I nodded eagerly. “Then sit back and prepare to have your pedo mind blown.” Slowly, she lowered her hips down to mine, and her lips began to part as her pussy stretched to wrap around my swollen glans. Her outer lips slathered their warm, slippery secretions on my cock as more and more of it disappeared into her inner most sanctum. She was incredibly tight, but not painfully so. It certainly didn’t feel like Kate’s adult pussy. It gripped me with a lot more pressure that Kate’s snatch, like it was trying to wring the cum out of my dick. Thankfully, she was wet enough to reduce the friction and kept going further. Finally I bottomed out. My dick had reached her cervix with only about half of it inside her; she was only eleven after all. However, it felt otherworldly to be inside elementary school pussy, her thinly stretched outer lips kissing my shaft. It was truly a sight to behold as there was no public hair to obstruct my view of her little kiddie cunt impaled on my boner.

She winced, as it was only natural to feel a little discomfort. Even with her practice with dildos, she was still losing her virginity. “Are you ok?” I asked. “I’ll be fine. I just need to get used to it. I think I can start moving now”

The heat and pressure was already making my dick go crazy, but all that pleasure increased ten-fold once she started rocking her hips, stroking my stiff cock with irresistible eleven year old pussy. It took all of my willpower not to cum then and there. After all, I needed to give this cutie a good first time. While I was in pedo bliss, Sarah leaned forward and planted a big kiss on my mouth. I was surprised at first since it felt a little weird to be kissing Sarah instead of Kate as I did genuinely love her. That thought soon disappeared though as I was overcome by lust, and I quickly reciprocated. Our tongues danced around each other’s mouths as I was simultaneously embraced by both Sarah’s upper and lower lips.

My libido was going crazy! Fucking Sarah was my most perverted and deviant pedo fantasy come true. Her tight vaginal walls were sucking my cock, and I soon felt my sperm welling up to the tip of my rod. “I’m about to cum Sarah!” She gave me a playfully condescending look. “You’ll have to beg me if you want to do it inside me Jackie boy.” she teased.

“Oh please let me cum inside you! I want to paint your insides with my dirty pedo sperm! Please Sarah! Let me cum in your tight eleven year old loli pussy!”

“God you’re a pathetic pedo Jack. You’ve earned it. Give my my first creampie!”

I couldn’t take it anymore. My urethral dam burst and I flooded her insides with my hot sticky white cream. Her vaginal walls spasmed as they clamped down on my shaft trying to milk out every last drop. Spurt after satisfying spurt gushed into her preteen womb. I just couldn’t stop cumming. I had the most satisfying orgasm in my life and released more nut than I ever had before into a girl literally half my age. Her bald eleven year old kiddie pussy was too small to contain all of the semen, so it started spilling out on my belly. Finally my orgasm subsided and Sarah slid off of me, my enormous creampie spilling onto her bed sheets. I looked in awe at the trail of my cum spilling out of Sarah’s hairless, now depetaled flower. I didn’t care what happened to me after that. I just had the best sex of my life!

A few months later, Kate and I were having dinner. She looked extremely troubled. “What’s wrong Katie?” I inquired. “Oh Jack, you’re never going to believe this but Sarah is pregnant. We found out just after her twelfth birthday.” My heart sank while my mind raced with thoughts.

How can this be? I pondered in desperation. She hasn’t had her first period yet! Could she have lied… Oh Fuck! She must have been having her first menstrual cycle that day we had sex! I must have knocked her up when she was ovulating, a few days before she would have had her first period!

The look of shock on my face didn’t disturb Kate one bit, as it was a completely natural reaction to hearing the news that her twelve year old sister is pregnant. “Have you figured out who the father is?” I probed. “Sarah refuses to tell me or out parents” Kate relented. “But we’re going to do a DNA test, and we’re going to find out who violated her, one way or another!” I wonder if I should see if I can fuck Sarah one last time before I get my ass fucked in prison.
