Jimmy's Learning Curve

By Steve Ryan aka Fantasy Fiction

"Jimmy! Can you come here?"

Fucking Great! It's only the first week of no school for the summer and my sister is already starting to bug me.

"I'll be there in a while, I just got out of the shower!" I yelled back through the door of the shared bathroom that separated our bedrooms.

"OH! just throw on a towel and come here!" she yelled through the door.

My 12 year old twin sister was insistent, so I wrapped a towel around my waist and tried the door handle that led into her room. It was unlocked, I pushed it open and went in, pissed off that she was bothering me so early in the morning.

So, I guess I should tell you about us before I go on. My name is Jimmy, I'm 12 and just finished 7^th grade. I have short blond hair, blue eyes and a deep tan from swimming in our pool everyday after school. My twin sister Ann looks just like me but her wavy blond hair goes just below her shoulders. Our parents like to joke that if I grew my hair long people wouldn't be able to tell us apart.

"What's so fuckin' important?" I barked at her, instantly regretting my tone when I saw her eyes start to get watery.

"I.. I just wanted to get your opinion about my new bathing suit." She said in a teary eyed voice. "I didn't mean to bother you." She was wearing a floor length bathrobe and pulled it tight against her body as if shielding herself from my harsh tone.

I didn't mean to hurt my sister's feelings and said "I'm sorry sis, I didn't mean to snap at you. Sure, you can show me your new suit and we can go in the pool after breakfast."

This was our first year staying home alone during the summer and our parents felt we were responsible enough to be home and use the pool while they were at work.

Ann's spirits immediately lifted when I apologized, she smiled and told me to sit on the edge of her bed. She stood a few feet in front of me and let the robe drop to the floor.

"TaDa!" she giggled as it hit the floor.

My mouth dropped open as I looked at my twin sister. Her new bathing suit was nothing more than three patches of cloth. My eyes locked in on her top, two small triangles tied with string that barely covered her breasts. I never noticed my sister had tits, but there they were, like two Georgia peaches sticking straight out from her chest with only her nipples covered by cloth. Her ivory white skin contrasted with her deep tan and it almost looked like she was wearing a bikini top under her new top.

My eyes traveled down her chest, past her ribcage, past her flat tummy and paused at her bellybutton. I took in a breath of air as I lowered my eyes to the patch of cloth between her legs.

The bottom of her new suit was a small patch of material that left almost nothing to the imagination. I could clearly see the puffy camel toe the cloth covered.

When Ann saw where my eyes were focused, she slowly turned around to show me that the back of the suit was nothing more that a string nestled deep in the crack of her ass.

"Wow!" I whispered and took in the sight of my 12 year old sister. The skin on her hips, thighs and butt was just as white as her top and looked as smooth as silk. Her skin was flawless, with only a small mole on the inside of her right thigh about an inch from the patch of cloth that covered her pussy.

"Wow?" I said again, and searched my brain for any words to add.

"So, do you like it?" Ann asked. "HELLO! JIMMY! I asked if you like my new suit?"

"Um, yeah, it's amazing!" I answered. "Does Mom know you got it, I don't know if she'd approve." My voice of reason said.

"What mom and dad don't know won't hurt them! Besides, all the girls are wearing these suits nowadays, why shouldn't I?" she calmly defended herself.

"Where did you get it if mom didn't buy it for you?" I asked as my voice started to come back to me.

"Kathy got it for me." she answered.

Kathy was her 12 year old friend who lived down the block with her parents and 14 year older brother who just finished 9^th grade.

Ann went on to say "Kathy's mom is much more understanding and up to date with today's fashions. She actually paid for it, but Kathy picked it out for me, and she picked out one in another pattern. Let me show you!"

I expected my sister to hold out another flimsy bathing suit to show me, but she didn't. She pulled the strings at her top and let it fall to the ground, exposing her coral pink nipples to my gaze.

"Fuck!" I whispered under my breath as I looked at her perfectly formed peach shaped tits.

I held my breath as my 12 year old sister put her thumbs on the strings to the bottom part of the suit. She looked me straight in the eyes and pulled it down and off her legs.

"Oh, fuck!" I softly moaned as I took in the sight of the fat pussy lips between her legs as she stood completely naked in front of me.

"Here's the other suit!" she giggled and threw a yellow clump of cloth at my face. "Which one do you like best?" she asked as I caught the flimsy material.

"I.. I don't know." I barely whispered.

"Well, I think you like my birthday suit the best!" she giggled and pointed between my legs.

I looked down and saw my 5" boner sticking out from the towel, the head was shiny with a drop of precum.

"Oh shit! I'm sorry sis." I mumbled and tried to cover my hardon.

"I'm not sorry, a girl likes to know she's appreciated." she giggled "Do you like my body, Jimmy? Do you think I'm sexy." she asked as she turned around several times. "I think you do. At least your cock thinks I'm pretty and sexy."

"OMG, you're beautiful, sis. I.. I guess I never really noticed before. I mean, after all, you are my sister." I said.

"Kathy's brother thinks she's sexy too, Jimmy. And she thinks he's sexy. They even do sexy stuff with each other. Would you like to do sexy stuff with me?" she whispered.

My brain struggled to take in everything that had happened since I walked in the room. Was my sister really asking me to do sexy stuff with her? Yes, that's what she said. She asked if I would like to do sexy stuff with her. "Sure!" was all I could answer.

"Oh goody!" she said and lightly clapped her hands. "I was hoping you would want to!"

I watched as my sister walked over to where I was sitting. I didn't move as she pulled the damp towel from me and exposed my throbbing boner to her view again.

"Oh, Jimmy! It's beautiful! I could just eat it all up!" my naked sister said as she got on her knees in front of me and wrapped her hand around my cock.

"Close your eyes, Jimmy. I want to try something." she whispered.

I did as she said and immediately felt like I had died and gone to heaven. My 5" cock was enveloped in a wet warmness it had never felt before.

I opened my eyes and looked down, all I could see was a mass of blond hair moving up and down between my legs. I was getting a blowjob from my sister, my first blowjob! And it was from my own twin sister!

I carefully put my hands in her hair and pulled it back so I could watch what was happening. I moved her long blond hair from the right side of her face and saw her mouth was down to the root of my cock. She opened her right eye and looked me in the eyes as she pulled her mouth off long enough to say "Cum when you need to, Jimmy. It's okay, cum in my mouth, I wanna feel you shoot off in my mouth, I wanna eat your cum." Then she lowered her head and started bobbing her head up and down my hard boy boner.

My first blowjob couldn't have lasted more than a few minutes, but I would remember it for the rest of my life. I had the most intense orgasm I had ever had and blasted at least five jets of jizz in my sisters mouth. She swallowed it down and nursed on my cock till there wasn't a drop left in my boycock. "WOW! This is way better than jacking off!" I thought to myself.

Ann stood up, licked her lips and said "That was great, you did really good for your first time! I'm gonna go get some breakfast." she turned and headed to the kitchen still naked, swaying her hips to show off her cute little ass. I lay back on her bed, closed my eyes and thought about what had just happened. I reached for her pillow and held it to my face, breathed in her young girl scent and drifted off to sleep.

I don't know how long I was out, but I woke up to the wonderful feeling of my cock in my 12 year old sisters warm mouth, I looked down so I could watch her sucking my cock. Our eyes met and she took my cock from her mouth.

"Hey, sleepyhead. I figured that would happen, Kathy says her brother falls asleep sometime's after sex. But it's time for you to wake up and do some more stuff with me!"

And more stuff was exactly what we did. Before our parents got home my sister taught me how to properly kiss a girl with my tongue deep in her mouth, how to suck tits to bring the most pleasure to a girl, and the proper way eat pussy! We did a 69 and I ate her out while she sucked me off, she even stuck her finger in my ass, so I did the same to her. She was sliding two fingers in and out of my asshole when I filled her mouth with my second load of jizz.

We both dozed of after that and she was still sleeping when I woke up. I stared at her smooth naked body and reached over to run my hands over her firm tits, lightly pinching her pink nipples till they stood out from the white globes sticking out on her chest. I moved my hand down to her smooth cunny and slid a finger across her fat, swollen pussy lips.

"I guess I dozed off." Ann said in a sleepy voice. "Jimmy, I want to feel you inside me. I want your hard cock in my pussy. Fuck me Jimmy." My 12 year old sister begged me.

I guess she sensed I didn't have a clue how to properly do it. She spread her legs and pulled me on top of her, grasping my cock in her right hand she rubbed it inside her slit then lowered it down to her tight pussy hole.

"Push in in Jimmy." she said as she dug her heels into my ass and pulled my cock into her.

A feeling of deep of love passed through me as my 5" cock slid deep into my sister's slick pussy. "I'm fucking, I'm really fucking!" I thought to myself. I swear I didn't stop kissing her and sucking her beautiful tit's the whole time we fucked.

We fucked off and on the rest of the day, which was as soon as I got hard again. Before I knew it, it was time to get dressed and act like a normal brother and sister when our parents got home.

I woke the next morning from sounds coming from the bathroom I shared with my sister. Turning my head to see the clock I knew my parents had been gone for at least 30 minutes and both would be at work by now.

"Morning" I called to my sister through the closed door.

"Oh, you're awake, good. Take care of your morning business and get the shower warmed up so we can take one together." Ann answered from the closed door.

Visions of my naked sister flashed through my mind and I went into the bathroom after I heard her door close. After taking care of my morning bathroom business, I turned on the shower. As soon as the water was warm enough I called to her as I got in "Sis, shower's ready!"

We share a large walk in shower with glass from the floor up. Ann stepped in behind me.

"Good morning, brother." she said in a very sexy voice.

"Good morning, sister." I replied, trying to sound as sexy as she did. I couldn't help but stare at her beautiful naked body.

"Let's wash each other." she said and reached for the bottle of body wash we shared.

Ann and I spent the next twenty minutes lathering each other, she washed my hair and I washed hers. She slid her hand under my balls and paid a lot of attention washing my asshole and even slipped a soapy finger in it. I spread my legs wider and let out a moan, it only encouraged her to push in another finger.

Her lips were touching mine as she whispered "You like how that feels, don't you Jimmy? You like getting your asshole finger fucked by your sister, don`t you?" then she said in her sexy voice "I do too, Jimmy. Finger fuck my ass while I do yours."

We spent the next few minutes with fingers in each others assholes, I thought my cock was going to burst it was so swollen. Ann pulled away, got behind me put two fingers back in my asshole and reached around with a soapy hand to stroke my cock. I don't think she noticed when I brought my fingers up to my nose, sniff them and put them in my mouth. I was wrong.

My 12 year old sister put her mouth close to my ear and whispered "Yeah Jimmy, lick my ass juice off your fingers while I jerk your cock and finger your asshole. I wanna make you cum, I wanna see your hot jizz shoot from your fat cock, gimme your hot fuckin` load of spunk."

"FUCK!" I cried out as I shot my load out onto the cool shower tile. Ann kept stroking my cock till it was drained, then slowly pulled her fingers from my ass, held them to her nose, and put them in her mouth. I couldn't believe my sweet innocent sister could talk and act so nasty. But I loved it!

"I need dry off and brush my hair, come in my room whenever you're up to it." she giggled and gave my soft cock a squeeze.

After drying off, I walked into my sisters room and found her laying naked on her bed, she had both hands on her tits and was pinching and twisting her pink nipples the same way she showed me how to do yesterday.

"You look so sexy, Ann." I told her.

"So do you, Jimmy." she said "Would you like to try some more sexy stuff with me? There are some things Kathy and her brother do that I would like to try with you."

"Sure, I'll do anything you want me to." I answered "But I'm curious, what's up with Kathy and her brother?"

Ann gave me the short version. Kathy and her brother had been fucking each other for two years, ever since she was 9 and he was 11. My sister said she found out about them and was invited to join in six months ago. Every time she went over for a sleepover the three of them got together for sex.

"There's more to the story, but I don't want to get into it now." she said "Are you sure you'll do anything I ask you to?"

"Yes. Anything, sis" I answered.

"Mmmmmmm, okay. Lay facedown on my bed and put a pillow under your hips so your ass in in the air and spread your legs." she told me.

I wondered if I made a mistake when I said I would do anything, but I did as she told me. I buried my face in a pillow and closed my eyes, anxious to know what she had planned. I heard a dresser drawer open and close and a couple of minutes later I felt her weight on the bed.

"I think you're really gonna like this, Kathy`s brother loves it." she whispered.

"Ohhhh" I moaned out loud. I instantly knew what my sister was doing, she was licking my asshole. "Ohhhh fuck, that feels good!" I moaned.

"I thought you'd like it. Kathy and her brother do it to each other all the time. It's called rimming." she told me before lowering her hot mouth to lick my asshole again.

My 12 year old sister licked and tongued my asshole for at least ten minutes, she pushed her tongue in my asshole over and over again as I moaned in pleasure.

Ann pulled her mouth from my ass and I heard something squirt from a bottle "Time for a little lube." she said. I kept my eyes closed and waited to see what she was going to do next. It wasn't long till I felt her stiff finger enter my asshole.

"Uuunnnggghhh...ooooooh!" I moaned as she drilled her finger deep in my asshole. Her finger was soon joined by another one and then a third. I couldn't stop moaning from the pleasure I felt from her fingers.

"Mmmmmm, I think you're ready now." she whispered.

I heard the squirt, squirt from the bottle of lube. I could feel my sister's slender legs between mine, she spread my ass with one hand and I felt something firm against my asshole.

"You should be loose enough." she said "Just need to give a push."

I felt something enter my asshole, it was larger than her finger and seemed thicker than her three fingers together. It didn't really hurt so I didn't say anything as she pushed her hips till they were pressed against my ass cheeks. My ass felt full, not painful, but full. She pulled back and my hole suddenly felt empty.

"Did I hurt you? Do you want me to do it again?" she asked me.

"Um, yeah. You can do it again, but can you use some more of that slippery stuff first?" I asked her.

"Squirt, squirt." I heard her squeeze more lube onto whatever she was pushing up my ass. Then it was back at the entrance of my asshole and sliding in.

"OH JEEZ! UNGH! UNGH! UNGH! UNGH!" I moaned into the pillow as she moved faster and faster in and out of my ass. I turned my head and looked at her dresser mirror wondering what could be giving me so much pleasure. I was a little shocked as I watched my sister slam her hips against my ass, as she pulled out I could see she had a big cock strapped between her legs and she was fucking my ass like I fucked her pussy yesterday.

Ann saw that my head was turned toward the dresser mirror and said "Do you like getting assfucked, Jimmy? Kathy's brother loves it when she fucks him in the ass."

"UUUNNNGGGHHH! YES, IT'S FANTASTIC! AAAGGGHHH! DO IT! FUCK ME! FUCK MY ASS, SIS!" I cried out as she pounded my ass pussy.

"Oh Jimmy! You like it don't you, I like it too, I love getting fucked by my brother and fucking him in the ass!" She then said "I wanna make you cum, Jimmy!"

My 12 year old twin sister reached around my hips and wrapped her hand around my hard cock. I raised my hips from the pillow, got on my knees and pushed against the cock in my ass. Ann was now on her knees, one hand on my hips and the other wrapped around my 5" cock, stroking it to the base every time she bottomed the rubber cock in my asshole as she fucked me doggie style.

"NNNAAAGGGGHHHHHH! OH, SIS... YES, YES, YESSSS! RAM IT UP MY ASS FAST AND HARD AND... AAAAAHH... DE-DDEEEEPPP!!!"

I cried out as she slammed against me.

"DO IT! I'M CUMMING! FUCK MY ASS! I LOVE IT! OOOHHH! YES! DO IT! DO IT! I'M CUMMMINNNGGG! I'M CUMMMINNNGGG!" I yelled out and shot a huge load all over her pillow.

My sister milked the last drops of cum from my cock onto her pillow to join the large puddle of jizz already on it. She backed the rubber cock out of my asshole, and I felt an emptiness as it fell out.

"Jimmy, don't get mad, but Kathy said I should do this too." she whispered.

"Do what?" I asked before she put her hand on the back of my head and pushed my face down into the pool of jizz on her pillow.

"She said I should make you eat your cum." Ann said and held my face in the thick white jizz. "Eat your cum Jimmy, lick it up and swallow it like I ate it yesterday. You said you`d do anything I asked you."

My sister didn't know that I was already used to eating my cum every time I jerked off. I'd grown to love the taste of my jizz ever since the first time I dipped my tongue into that creamy hot liquid. I licked and swallowed my jizz off her pillow till there wasn't a drop left.

"Good boy! Good boy, Jimmy!" my twin sister praised me.

She got off the bed, unbuckled the harness with the rubber cock and went into the bathroom. I got up and followed her. I watched her carefully wash the cock with warm soapy water and was a little shocked at how big it actually was.

"That whole thing was in my ass?" I asked.

"Yup, all the way to the base. You sure seemed to like it, didn't you." She said.

"Yeah, I guess I did. I'm just glad I didn't see how big it was before you put it in me!" I laughed.

"It's not that big, only about 8 inches, watch this!" she said.

I watched as my 12 year old twin sister tilted her head back and slid all 8" of the cock down her throat till her lips touched the base. She slid it in and out a few times to show how easy it was for her to take it all the way down.

"Here, you try it." she said and held the spit soaked cock to my face.

I didn't hesitate or think it was weird, I just opened my mouth and let her to put it in. I moved my mouth back and forth and wondered in the back of my mind what a real cock would feel like sliding in and out of my mouth.

"Not bad for your first time, if you want I can teach you how to take it all the way to the base." she told me.

"Yeah, sure. But right now I need a shower!" I laughed and turned on the water. I squirted body wash in my hand and washed the lube off my ass. My asshole felt soft and pliant as I washed it and I figured it was due to the assfucking.

I got out of the shower, dried off and went back into my sisters room. She was on the bed, on her hands and knees and looked at me.

"Wanna fuck my ass? I love a nice hard cock up my shit chute!" It sounded almost like a plea.

I looked down at my cock, it was already sticking out to it's full 5" length. "Hell yeah!" was all I said and got on the bed with her.

Ann spent the next few minutes teaching me how to rim her ass and get it ready for my cock. She showed me how to push lube in her asshole and to lube my cock. I pushed my cock in started to gently fuck her ass, but I ended up pounding her as hard and fast as I could when she begged me to fuck her asshole deeper harder and faster. I pumped my hot load deep in her guts and felt her asshole squeeze and milk my cock. When I pulled out she turned and swallowed my cock down her throat, sucking her ass juice and my cum from it. I rolled over and closed my eyes. I heard the shower start to run as I fell asleep in her bed.

I woke up and heard her say "Okay, I'll talk to you later!"

"Who were you talking to?" I asked.

"Oh, that was Kathy. She invited us over to her house tomorrow, she said we can spend the day. I'll ask mom if it's okay when she gets home from work." she told me.

Ann and I had a late lunch and spent the rest of the afternoon in the pool and sunning. I found it hard to take my eyes off her body in her new bathing suit. We didn't do anymore sex stuff the rest of the day, but we did slather lotion on each other so we wouldn't burn and I let her show me how to suck the rubber cock and take down my throat. She told me "It's a skill everyone should know how to do." Ann praised me on how quickly and easily I learned to do it without gagging.

Later that night, Ann asked our mother if we could spend the day at Kathy's house tomorrow and she said it was fine with her as long as we were home for dinner.

The next morning I was a little anxious about going to Kathy's house. What I really wanted to do was fuck with my sister all day and I was pretty sure we wouldn't have enough time when we got back home. But I figured it would be fun to hang out with Kathy and Billy, after all, he did have a new Play Station 5 we could play while Ann and Kathy hung out at their pool or did whatever girls like to do besides shopping.

Ann and I were dressed in shorts and t-shirts and she had her backpack with her.

As we walked to the end of our block I pictured Kathy and her brother in my mind. Kathy was 12 years old like my sister, but didn't look anything like her. Kathy took after her mother, who is Asian. She's a couple of inches shorter than my sister and has the natural darker creamy skin color like her mother, she has a pretty face, slightly almond eyes, and straight black hair that goes to the middle of her back. But she has always dressed "frumpy", wearing oversize shirts and baggy pants. I figured she must be ashamed of her body because of the way she dressed.

Billy was two years older than the rest of us, he was a couple of inches taller than me and looked more like his father and you would never guess his mother was Asian except he has the same dark cream complexion as his sister. Girls would refer to him as a "hunk" and I'm sure he could have pretty much any girl in school that he wanted. I'm not sure why, but my cock twitched as I pictured him.

Kathy let us in when we arrived, she was in the same frumpy clothes she always wore. Billy was on the couch watching TV, he was wearing basketball shorts and a sleeveless t-shirt that showed off his developing muscles.

Billy looked up at me when I entered the living room "Hey Jimmy, how's it goin`."

I laughed and said "I'm okay, how about you?"

I found it hard not to take my eyes off him as we talked, his smile and friendly personality were mesmerizing. I could hear the girls talking in the background but wasn't paying attention to what they were saying.

"Jimmy! Jimmy!" I heard Ann's voice pull me from my conversation with Billy. "Well, do you wanna?"

I turned my head "Do I wanna what?" I asked having no idea what she had asked me.

"Do you wanna get naked? I asked you if you want to get naked! Kathy and I are and I'm sure Billy is to, aren't you Billy?"

"Hell yeah! Let's all strip down and have some fun!" Billy exclaimed.

"If you guys are, I will too." I answered. I don't exactly know why, but I was excited to see Billy naked, I wondered what his cock looked like.

Within in a matter of seconds, we all stripped. I kept my eyes on Billy the whole time and stared at the 6" cock that hung between his legs. He was soft and it was still at least an inch longer than mine when I was hard.

"Nice cock, Jimmy. It's a real beauty." he said when I dropped my shorts.

"It's not as big as yours." I said, slightly embarrassed mine looked so small.

"Hey, I'm older than you. Your's will get bigger as you get older. But to tell you the truth, I think your's is perfect just the way it is." Then in a low whisper "I love young boycocks."

His words of encouragement made me feel much better and more confident.

"Are you boys going to stare at each other all day or are you going to look at us too?" I heard my sister laugh.

She was right, I turned to look at the naked girls behind me.

"Holeeee Shit!" I said, unable to say anything else when I saw Kathy. I was shocked to see what those frumpy clothes had been covering.

She was gorgeous! Her breasts were at least twice the size of my sisters, they looked like she had been wearing the same type of bathing suit as Ann because only part of her tits were a lighter cream color from being covered by the thin strips of cloth of her top. Her nipples were not coral pink like Ann's, they were thicker and very dark brown. My eyes traveled down her perfectly formed body and rested on the light creamy skin and the hairless smooth slit between her thighs.

"I guess you like what you see!" Ann laughed at me and pointed to my already stiff cock.

"You can touch me if you want to Jimmy, it's okay, I'd like that." Kathy said in a low seductive voice "Come here and feel my boobs, they love to be touched... and sucked."

I walked over to her, took her head in my hands and kissed her the way Ann had taught me. Her mouth opened and she pushed her tongue into my mouth. I lightly sucked on it the way my sister taught me, then I pushed my tongue into her mouth and she sucked it with more suction which made my cock throb.

It seemed like a dream, I was light headed as things started happening. Kathy gently pushed my head down to her magnificent tits and I latched my mouth around a thick brown nipple.

While I suckled her breast, I felt hands move my legs apart as someone sitting on the floor got between us facing me.

"Mmmmmmmm! Mmmmm! Mmmmmmmmm!" I moaned as a warm wet sensation enveloped my throbbing cock. I figured Ann was between us sucking my cock while I sucked her best friend's tits.

I opened my eyes and looked down to see my sister, but it wasn't Ann sucking my cock, it was Billy. I didn't bother me at all, it seemed natural to have a guy suck my cock, and I couldn't help but wonder if Billy would let me suck his later.

I guess my sister was reading my mind as she put her lips next to my ear and whispered "It feels real good, doesn't it? I can tell you like the way Billy sucks your cock. I'll bet you'd like to suck his, wouldn't you?"

I took my mouth from Kathy's thick nipple and answered my sister with a nod "Yeah" I groaned.

Kathy, Billy and I untangled. My sister took control and had me lay on my side, she arranged Billy next to me so we were in a 69 position. The living room carpet felt soft against my skin and I was glad we weren't on a wooden floor. Billy didn't touch me as I studied his cock, I reached out and held it in my hand only inches from my face. I guessed it had to be at least 7" hard, maybe a little longer. His cockhead looked like a torpedo with only a small ridge before the shaft. The thought struck me that it could easily slide down my throat or up my ass without any problem.

"Go ahead, Jimmy. You know you want it." Ann whispered in my ear.

"Yeah, Jimmy. Suck my brother's cock!" Kathy chimed in.

I leaned forward, opened my mouth and licked around his cockhead. It felt good, without any shame or guilt I moved my mouth down till half of his shaft was securely inside. It was better than I imagined, soft, smooth but hard at the same time, like a velvet covered piece of steel, nothing at all like the hard rubber cock my sister had me practice on.

"UUUUnnnnnggghhhh! Ooohhhh, fuck! This is all I've been able to think about since Kathy said you were coming over." Billy softly said.

I was surprised, Billy had been thinking about me? He thought about me sucking his cock and he wanted to suck mine? I was elated to hear his words and I moved to take his cock deeper.

"Remember what I showed you yesterday, take a breath and swallow as you go down. Get as much spit in your mouth as you can and push your head down." my 12 year old sister whispered instructions to me.

I remembered how I did it yesterday, I took a deep breath and pushed. Yes, yes! Billy's cock pushed past the entrance of my throat and my nose was touching his body. I pulled back and gasped for air, then plunged back down, taking his cock deep into my throat. Again and again I swallowed his cock to the root.

"It's all the way down your throat Jimmy! Kathy, look! Jimmy's taking your brother's cock all the way down his throat!" My sister sounded so excited and proud that I was able to swallow all of Billy's cock.

Kathy was on the other side of my sister and moved her mouth to my ear "Suck him Jimmy! Suck my brother's cock, suck him off and he'll give you a big load of hot creamy spunk. Yeah, you're gonna love a mouthful of my brother's hot jizz!"

I was turned on almost as much from the nasty girl talk as I was by the 14 year olds cock I was sucking.

"Yessss ... oh ... suck ... me ... oh ... just like that ... ohhhh ... yessss ... suck my cock ... " Billy moaned before taking my 5" boycock back into his mouth.

It only took a few seconds before we both started shoving our hips forward, fucking each others mouths like our lives depended on it. Billy reached between my asscheeks and pushed a finger in my ass causing me to thrust deep into his mouth.

"FUCK HIS FACE, JIMMY! FUCK HIS MOUTH AND RAM YOUR COCK CLEAR DOWN HIS THROAT!" Kathy commanded "FUCK IT JIMMY! FEED HIM YOUR LOAD AND HE'LL SHOOT OFF IN YOUR MOUTH! YEAH, ALL THAT DELICIOUS CUM IN HIS BALLS IS YOURS TO EAT!"

"I CANT HOLD IT! I'M GONNA CUM! OH, FUCK! FUCK! I'M CUMMING! I'M CUMMING, CUMMMMMIIIIINNNNNGGGGG! AAAGGGHHH! AAAGGGHHH!" I cried out.

Billy pulled his mouth till only my cockhead was in his mouth and yelled "ME, TOO! I'M CUMMING, TOO! OOOOHHHHH! UNG, UNG, UUNNGGGG!!!"

I pulled my mouth back so only his cockhead was in my mouth, I didn't want to waste any of his cum shooting down my throat. I wanted to savor the mouthfull he was going to give me as I filled his mouth with my jizz.

I wasn't disappointed, Billy squirted his hot spunk in my mouth, I loved the feeling as it shot across my tongue and slipped down my throat. I let it fill my mouth and moved my tongue through it as I swallowed. Kathy was right, her brothers jizz was delicious. Billy was doing the same wonderful things to my cock as I was doing to his and we nursed on each others cocks till they were drained.

I soon heard slurping noises and looked past Billy's thigh to see my sister and Kathy in a heated 69. They were licking and sucking each other cunts while finger fucking each others assholes. Kathy was on top of my sister and I watched her cute asscheeks squeeze together as she spasmed from my sisters tongue and finger.

"Shit!" I thought to myself, "I hope I get to fuck Kathy's hot cunt!" I knew it would be awhile before I would get hard again so I just let my imagination do the work and thought about pumping a huge load of jizz in her 12 year old tight cunt.

"Dude, that was awesome! You really gave me a mouthful!" Billy said.

"Yeah, that was pretty neat." I answered as I watched Kathy and my sister start to orgasm. "Do you think Kathy will let me fuck her later?" I asked.

"Hell yeah! She's had a bit of a crush on you for awhile, I know she wants to feel your cock in her little cunnie." Billy answered.

When the girls finished getting each other off, they suggested we should all go in the pool to cool down. Since they had a high wooden fence around their backyard we went out naked and jumped in the water. The four of us swam and played grab ass for the next half hour. I was getting hard and horny again.

I swam up to Kathy and bluntly asked "Kathy, can I fuck you?"

"Ooooo yes! I was hoping you'd ask! You can fuck me anytime you want, Jimmy." she gushed.

We got out of the pool and she led me to a grassy area under a shade tree "Let's do it here, it nice and cool."

"Okay" I said and watched her get on her hands and knees.

"Do me doggie style! Fuck me like a dog!" she giggled and moved her little ass from side to side.

I got on my knees behind her "What a cute asshole" I thought as I looked at her pink pucker. Not able to stop myself I leaned down and swiped my tongue across her asshole.

"OOOOHHHH!!!" she moaned. "That feels good!"

I decided to try my newly learned rimming skills on her sweet little asshole. I licked her pink hole over and over before sticking my tongue deep into it. The 12 year old clenched her sphincter and squeezed my tongue, we played this game for a few more minutes till she stopped me and asked.

"Do you want to fuck my asshole, Jimmy? I don't mind if you do, I love getting assfucked as much as getting cunt fucked."

"Don't we need some lube?" I asked.

"Billy, bring the lube over here!" she called out to her brother.

Billy and my sister came running over with the lube and sat on the grass.

"Are you gonna fuck Kathy in the ass, Jimmy?" my sister asked "Kathy loves a hard cock in her ass, I even use a strap-on in her ass like I did with you."

Billy was way ahead of the game and was already squirting lube on his sisters asshole and pushing a glob in with his index finger.

"Just getting her ready for you." he said "Now, it's your turn." he said and squirted lube on my boycock and ran his hand from the tip to the base. "There ya go, all ready."

I lined my cock up to the pink ring of Kathy's asshole, ready to push it in when my sister yelled "Wait! Stop!" I paused and watched her move in front of Kathy and spread her legs "Eat me out while Jimmy fucks you!" she said.

"Yeah, give me that hot cunt! I'll eat a box lunch while your brother rides the Hershey highway!" Kathy laughed.

Okay, now that my 12 year old sister was in place I again lined my cock up to that sweet looking asshole and gave it a gentle push. I guess I didn't need to be gentle because Kathy pushed her ass hard against my hips till my cock was fully lodged in her asshole.

"YOU'VE GOT IT... UP MY AASSS!!!!" she screeched as she feasted on my sisters pussy "OOOHHHH! BUGGER ME! BUGGER MY ASS GOOD AND HARD! DO IT, JIMMY! FUCK ME! FUCK MY ASSHOLE!"

Kathy went wild, pushing her asshole back and forth on my cock while trying to keep her mouth on my sisters snatch. Ann held a handful of Kathy's long black hair to keep her mouth from leaving her dripping cunt.

"Fuck, I can't take this anymore! I wanna fuck your ass Jimmy!" Billy said.

"Do it, Billy! Fuck my ass! Fuck my ass while I fuck your little sister!" I ordered him.

I heard the squirt from the bottle of lube and felt his finger enter my ass. Just a quick squirt, a quick finger and the next thing I knew he was pushing his 7" cock in my ass.

Kathy continued to push back against me and with every push Billy's cock bottomed out in my ass. It didn't take the four of us very long to get a rhythm going. Kathy ate my sisters cunt, I fucked Kathy's asshole and her brother fucked my asshole. The sensations were overwhelming as we fucked our brains out under the shade tree.

"HERE IT COMES!" I yelled as my cock began to spurt. "HOT SPERM! UP YOUR ASS! SQUEEZE IT, KATHY! MILK MY BALLS! I'M CUMMING IN YOUR ASSHOLE!"

I yelled over my shoulder "FUCK MY ASS! FUCK ME, FUCK ME! GIVE IT TO ME HARDER BILLY!

DEEPER! I CAN TAKE IT! DO IT AS HARD AS YOU CAN! REALLY GIVE IT TO ME!"

Billy pounded my asshole as hard as he could while I filled his little sister's asshole with my hot spunk.

I'M GONNA BLOW MY NUTS RIGHT UP YOUR FUCKING ASS, JIMMY!"

"OOOHH FUCK! HERE IT COMES! HOLY SHIT! I'M CUMMING!" Billy yelled, plunging forward deep into my ass. I swear I could feel every spurt of his hot jizz coating my insides.

The four of us pulled apart and lay on the grass panting as we caught our breath. Not a word was spoken as we regained our strength.

12 year old Kathy was the first to speak "I need a shower!"

"I could use one too!" my sister giggled as she said it.

I watched Billy and the girls stand up, then Ann and Kathy lay back down to face each other. Maybe they were too tired to go in and take a shower? I thought. But that was not the case, Billy stood over them, aimed his cock, and started pissing on them!

"Come on Jimmy, the girls said they need a shower!" Billy called to me.

Kathy and Ann started laughing and giggling as the first yellow stream of piss hit them. They held their tits and said "Piss on our tits! Piss on our tits."

I scrambled to my feet to join in, I really needed to pee and this looked like a new kind of fun. I aimed my cock at their tits and let it fly! The two girls started scooting down on the grass, if they weren't careful our piss would hit them in the face. Just as I was about to warn them, Billy aimed his piss stream directly at their faces.

"Oh fuck, yeah, yeah!" they both cried out as his hot piss covered their faces.

"I guess they like it." I thought to myself and aimed my stream at their faces. Billy and I moved our cocks back and forth from their hot little cunts to their piss covered faces till we were both empty.

The girls shared a deep pissy kiss. Kathy looked at her brother and asked "Do you feel like doing a little clean up?"

"You fucking know it, sis!" he answered.

I watched Kathy roll into a ball till her feet were on either side of her head and her asshole was pointed up to the sky. Billy wasted no time getting on his knees, then started licking my spunk from her well used asshole. He acted like a kid with his face in a bowl of ice cream, sucking and slurping every drop of the cum load I had pumped up his 12 year old sisters asshole along with our combined piss. When he was done he sat back on his heels and wiped his face with the back of his hand.

Billy looked me straight in the eyes and said: "Fucking delicious, you should try it next time!"

I told myself "I think I will give it a try sometime, maybe with my sister when were home alone." Then I noticed movement at the back of the high fence.

"What's that?" I asked out loud and pointed to the fence.

Billy laughed "That's just old Mr. Johnson that lives behind us. He likes to come out and watch through the fence."

Billy told me when he was 8, he discovered the little wooden door that Mr. Johnson had made in the fence. It opened from Mr. Johnson's side and was just the right height and size for the old man to put his cock and balls through. The first time he saw the cock come through to his side of the fence he went over to play with the new toy.

"I don't know why, but I just wanted to put it in my mouth, so I did. I've been sucking Mr. Johnson off since then. One day Kathy came out and found me sucking his cock and she joined me, she was only 6 back then. I guess we both got our taste for cock from him."

"Wow!" was all I could say.

"Lets go give him a double header, Jimmy." Billy said and ran to the back of the fence. I quickly followed, anxious to see my first adult cock.

I looked at the cock that stuck through the little door in the fence, it had to be at least 9 or 10 inches long, it wasn't as thick as I thought such a long cock would be, only a little thicker than Billy's. I reached out and wrapped my hand around it and stroked it from the tip to the base where two large fat balls hung through to our side of the fence. There was a low groan from the other side. It wasn't long before Billy and I had both our hands wrapped around the long cock and there still room for more!

We stroked the big cock till clear sap started bubbling from the pisshole, then we got to our knees and started licking up and down the sides. Our tongues made contact and we move to give each other a deep kiss before returning to the adult cock.

Up and down, back and forth, Billy and I licked, sucked and stroked the big cock. Billy put the fingers of one hand around the base of Mr. Johnsons fat balls and tugged and twisted them.

That was all the old man could take, he let out a loud groan and spunk started pouring out from his cock. Billy and I moved our mouths at the same time to the tip and let the hot jizz cover our lips and drip down our chins.

When the old man's jizz stopped flowing, Billy moved his mouth to mine and we kissed, rubbing the man's spunk all over our faces till they were covered like a glazed donut.

Mr. Johnson's cock pulled back from the hole to his side of the fence and the little door shut.

"That was so cool!" My sister said as she and Kathy came over and licked the slime from our faces.

The four of us spent the rest of the day snacking and watching TV. Billy and Kathy told me stories of their sexual adventures with other kids in the neighborhood. A lot of stuff I never would have thought of doing, until I heard it from them. My 12 year old sister just nodded her head when I looked at her, as if to say "Yup, they told me that story too!"

Before we knew it, it was time to head back home. Kathy asked if we could come back tomorrow and Ann told her "We'll have to ask our mother."

When we got home we had enough time to take a shower and spread sunburn lotion on each other. Ann told me she wanted to wear her new bathing suit next time she was in the sun so she could get tan lines like Kathy had.

After dinner, Ann asked if we could go back to Kathy's tomorrow and our mom said it was okay with her, especially since Billy was older and more responsible.

My twin sister looked at each other and shared a secret smile. We were both thinking the same thing "If mom only knew!"

Ann made the call "Hi, Kathy. My mom said we can come over tomorrow!"

"That's great!" Kathy answered "Billy and I are baby sitting a couple of kids tomorrow, we'll have even more fun!" She hung up the phone without mentioning who they were babysitting for.

"So who are they baby sitting tomorrow?" I asked my sister when she told me about the phone call.

"I don't know, I forgot to ask!" she answered.

"That's okay, we'll find out tomorrow!" I told her, thinking of different possibilities for more sex tomorrow.
