How I walked in on my sister and her friend having sex with backster her full blooded 110 lbs german Sheppard.
I just turned 16 at this time 6 feet tall slim athletic around 170 lbs white with a 8 Inch cock 2 inches thick with a mushroom head that was even bigger,
My 13 year old sister Chrystal was about 6 inches shorter with brown hair like mine. Hers was half way down her back. My hair was short. She had 34 b tits and a really nice ass that made my cock hard when she walked by in shorts or a tight crop top with her braless nipples poking out.
Her and her best friend would flirt and tease me, mostly make fun of me and then go out or lock themselves in her room. Mary Lou her friend was 14 and hot as fuck with smaller a cup tits shaped like champagne glasses topped with huge nipples. Long strawberry blonde hair I couldn’t stop staring at her camel toe when her and my sister sunbathed in the back yard.
They would giggle and whisper and sneak around.
It was early summer and Chrystal and Mary Lou sunbathing. Backster was usually not far from my sister.
I had just walked outside and saw backster humping the neighbors bitch. He was pounding away at some medium sized mutt.
I called out to my sister and said. Hey Chris look at your dog he’s getting him some.
She looked over and her expression changed when she saw her dog fucking some mutt .she ran over and tried to stop it yelling bad dog, but she couldn’t separate them he was knotted now standing butt to butt stuck together. She looked up at me and said help me get them apart.
I just laughed and went over to my friends house. Though I did think about the fact that my sister and her friend were overly upset by backster getting himself some pussy.
I had a female German shepherd named Sheila. I had been fucking her for several years and only did it when I was alone with my door locked, or if there were too many people around I would take her for a walk. I was finally able to get my big cock in her when she came into heat for the first time. After that I fucked her almost every day.
Even when she was pregnant ,we sold all the puppies.
One Saturday morning I was supposed to go over my grandparents house. But when I got there they had left a note saying that they had went to the hospital because one of there friends was there and we would go with them tomorrow.
When I got home my parents still weren’t home from the shopping and probably wouldn’t for a few hours. I had taken a shortcut through the backyard, I could hear the loud music my sister played all the time when she was in her room. When I got under her window I could hear voices, but couldn’t everything that was said. The window blinds were open a few inches and I put the step ladder up and peeked though her window. I couldn’t believe what I saw. My sister and Mary Lou were naked. They were putting socks on Baxters front paws and taping them on. He looked a little bit comical and was extremely excited his pecker was sticking out its sheath several inches.
My sister said to Mary Lou, I haven’t fucked him since last night,I want you to lick me while he’s fucking you okay.
Chris sat on the edge of the bed and Mary Lou got down on her hands and knees with her head between my sisters legs.
Baxter went from sniffing and licking there pussies. In seconds he mounted Mary,as he stabbed around she put her hand between her legs and guided him in.he started pounding immediately. I had been filming since they had put the Sox on his front paws. Mary grabbed his front paws. After a few minutes he stopped his frantic humping and layed on her back panting. I got off of the ladder and went inside when I got to my sister’s room it was locked.
I called out open the door.
No she said leave me alone, go away and stop bothering me.
I pushed the door hard twice and it popped open.
They both looked at me with stunned looks on them my sister yelling at me and trying to cover up.
Wait until I tell everyone I said.
Nobody will believe you now get out ,Chris said.
Yeah they will I’ve been filming you for the last few minutes from outside want to see as I walked over to where my sister was holding a pillow in front of her.
After showing her with her eyes flicking back andforth from me to Mary Lou with Baxter knotted in her.
Her demeanor changed, please don’t tell anyone, we’ll do anything you want won’t we Mary.
Mary said nothing just nodded her head.
Okay I said and dropped my shorts and boxers to the floor and got on the bed. When I reached my sister,she didn’t struggle when I pulled the pillow away and crawled on top of her pushing her back. I rubbed my my cock back and forth until I was lined up with her vagina .she was wet and in a few thrust I had my cock all the way in her. I kissed her and forced my tongue in between her lips grabbing her tits I started thrusting in and out of her. As she made moans and grunts and little by little started moving with me I had only ever had sex with my right hand or fucked my dog Sheila or had her lick the peanut butter off my cock as I jerked off and came on her face.
And my sister had never fucked a male human either. Although my cock was thicker than Baxters his was about 11 inches long from his knot which was the size of two golf balls that were molded together with his cock filling the space in between..
I was the hardest I’ve ever been, I had practiced with Sheila many times to see how long I could go without Cumming .
And that works pretty well when you’re in total control. But here is my sister fucking me back wrapping her legs around me,arms around my neck making all kinds of unhhs and other sexual sounds as I ram in to her our pubic bones giving off electric shocks every time I went balls deep into her. I felt her breathing get quicker she let out a long ohh god
And another oohhh goddd and started trembling then I’m cumming Ricky her pussy constricted on my cock wish I could say that my training with Sheila made me last for hours. But perhaps less than a minutes later I grabbed my sister by her ass cheeks and pumped several sqirts of cum deep in her pussy. I laid on top of Chrystal as we both caught our breath. She looked up at me and said you came in me didn’t you. You can’t do that I don’t want to get pregnant by my brother.
Well you better tell mom that you need to go to the gynecologist and get on birth control because I’m going to fuck you and Mary Lou anytime I want.
If you tell anyone especially your friends or show them any videos we won’t let you fuck us ever again will we Mary
Finally my cock slipped out of Crystal’s pussy, I watched as my cum oozed out of her pussy and dripped down her slit and dribbled on the bed.
Baxter pulled out of Mary Lou a couple of minutes later and she stood up and started collecting her clothes and putting them on.
What are you doing don’t get dressed I’m going to fuck you after my dick gets hard again. Come up here on the bed,I was in the middle of the bed and patted the other side that my sister wasn’t on. She sat next to me with her panties on. I slipped my hand across her small tits pinching her nipples and rolled them between my thumb and fore finger.
I placed her hand on my soft cock and said make me hard, my hand slipped underneath her panties and I felt her pussy. It was all wet and dripping down her legs from all of Baxters cum leaking out of her pussy. I easily slid two then three fingers inside of her pussy. I put my other hand on the back of her neck and pushed her towards my cock and said suck on it and make me hard.
I don’t know how she said to me .open your mouth and start sucking on it like a popsicle. I grabbed her hair and pushed her head down. It was only a few minutes and my cock was coming back to life. It’s only about 4 or 5 inches long when its soft and about as big around as a Italian sausage. My sister and Mary Lou never complained that it was too big having Baxters bigger cock in them.I never had a complaint that I was too small and only a few that it was too big. Very few. I was coaching her, now go up and down, don’t suck too hard and don’t use your teeth. It was hard again she could barely get the head in her mouth. I got up on my knees and had Mary Lou get on her hands and knees. I know you must like it doggy style I’m going to find out how much.
I found her hole right away and pushed the head into her and pulled back holding onto her hips and rammed almost all the way in her. She wasn’t as tight as my sister was but neither of them were after
Getting fucked by Baxter. After I cum and get hard again within a couple of hours I could fuck and not cum for maybe a hour or longer. Or at least till I drop from exhaustion. I was pulling all the way out and slamming my balls and hearing sloppy wet sounds as I fucked her she was pushing back hard in no time. Meeting every thrust moaning and I only remember her saying that’s it don’t stop I’m going to cum.I kept going with her Cumming twice more before I unloaded my cum deep into her pussy. I had pushed her all the way down onto her stomach before I filled her up with my baby seed. I laid on top of her with cock buried all the way in her after a while I pulled out and watched as my cum dripped out of her pussy and onto the sheets. I got up and said to my sister, I’ll be back after mom and dad go to sleep tonight.
They both got on birth control a couple weeks later and I fucked my little sister and her friend all summer long. And every chance that I got until I went to college and every time I came home..
