Me and my sister, Kasey, have always been close. We were just two years apart, almost to the day. Our birthdays are just five days apart and I honestly have no idea how our Mom planned that one out. We’ve always celebrated together in the middle, August 15th.

I was turning 16 this year and her 18 so it was pretty exciting for both of us. It was even better because the 15th fell on a Monday and we had the entire day to celebrate.

I knew Mom and Dad would both be out of the house by 7:00 am so I set my alarm for 7:30 not wanting to miss a single minute more. I woke to the sound of the alarm and patted the bed beside me but I quickly realized the my dog, Boss, was not in the room. Normally he’s either by the door or lying beside me waiting for me to let him out. I crawled out of the bed to go look for him.

Kasey’s room was right across the hall and as I stepped through my door I heard a soft moan coming from her room and noticed the door was cracked just a little. Like any 16 year old boy I put my eye to the crack to see what she was doing.

She laid on her stomach with a pillow underneath her, her shoulder length brown hair cascading over her face as one hand rubbed her cream colored pussy and the other rolled a rosy pink nipple between her fingers. Her deliciously perfect bubble butt was up in the air with her legs spread and Boss riding her with his cock in her perky pink asshole. She moaned as he slammed against her and I couldn’t stop myself from reaching into my boxers and wishing I had grabbed my phone.

I pushed the door open just a nudge for a better view. She slipped a finger into her pussy and pumped her hand to the rhythm of Boss slamming his cock into her ass. My hand sped as it stroked up and down my 6.8 inches.

I came about the same time as she did from the sound she made as Boss knotted inside her ass. I backed away before she realized I was there and went into the bathroom to grab a shower, having decided to let them have a few minutes to cool off before I took the dog out.

Boss was already outside chasing birds off the fence so I gathered my dirty laundry and took them into the wash room. Kasey followed me in wearing an old shirt that barely covered her B cups, exposing her pierced navel and the silver chain dangling down her belly pointing towards a pair of pink and white Hello Kitty panties.

“Hey baby brother, you don’t mind doing mine too do you?” she rubbed against me as she set her basket on top of mine.

“What do I get for it?” I moved my eyes towards her.

I know she’s my sister but, damn she was hot. I towered over her at 5”7 and 170 lbs but people still think we’re twins half the time.

“What do you want?”

Now that was a loaded question with a hundred different answers, none of them very brotherly.

“It’s our birthday,” I reminded her.

“I know, why do you think I got up at 7:00 on a Saturday morning?”

“I want you to be my slave for the day.” I grinned.

“A slave for the day huh? I can handle that I think,” she nodded.

“Then you best go cook our breakfast,” I added her clothes to mine and started the wash.

I followed her into the kitchen and watched as she danced around and pulled things from the fridge, pulled dishes from the cabinet, utensils from the drying rack, plugged in the toaster, and jumped up to grab the fry pan off its hook above the sink. After the third failed attempt I slid in behind her and lifted her by the waist.

“Why did I have to be the short one,” she laughed.

She lit the gas stove top and started a round of bacon before cracking half a dozen eggs into a bowl and mixing it with shredded cheese and milk. After giving the eggs a good beating she put two slices of bread into the toaster before flipping the bacon. Then she started a pot of coffee before pouring two glasses of orange juice.

“Why the Hello Kittys? I thought only preteens wore stuff like that.”

“And women who can’t fit the big girl panties,” she laughed.

“Come on, I’ve seen you in a thong Kasey, hell I just put three in the wash,” I laughed with her.

“Exactly, the only three that I own, in fact these are the only panties I have that still fit my fat ass,” she slapped her butt.

“Your ass is not fat,” I told her.

“Been looking at my butt baby brother?” she teased.

“Only when you walk around the house naked,” I shrugged.

“Want me to go put on pants?”

“No,” I said a little too quickly.

She smiled and shook her Hello Kittys for me.

I heard Boss scratching at the door, no doubt smelling food and wanting his share. I got up to let him in and he followed me into the kitchen. His head turned to Kasey and I slapped my leg and snapped my fingers until he sat beside me. I followed his eyes to Hello Kitty waving howdy on Kasey’s rear end.

“Good boy,” I gave his ears a scratch.

The toast popped up and she danced over to pull it out before putting more in, then danced back to the fridge and bent over for the jam then twirled back to the silverware drawer for a butterknife. She smeared a thick layer of strawberry jam on the toast then turned back to the stove.

She pulled the bacon from the fry pan and poured in the eggs with a splash. Boss jumped up but I growled “Sit,” and he sat back down. I got up and walked to her, slid my tongue across her cheek and licked the raw egg. She shivered and her hand shook a little as she stirred the egg.

“Eww,” she said but I could see it turned her on.

“Needs a bit of salt and pepper,” I grinned and reached over her to the spice rack.

She pressed her butt into me and I gave her a bump.

“Mom should put this stuff where everyone can reach it”

I wasn’t about to tell her that Mom had a step stool under the sink she uses.

The second round of toast popped up and made her jump. I grinned and smeared the jam on while she stirred the eggs with a wooden spoon until they were a nice golden color before turning off the burner and reaching for plates.

“No need to waste more dishes, just put everything on one plate and we’ll share.” I told her.

She poured two cups of coffee before sitting down beside me and we didn’t talk again until we had stuffed ourselves and given the leftovers to Boss. He was more than happy to give the plate a pre wash before we carried it to the sink. I dumped the bacon grease into a tin can while the water heated up, then went to pull the clothes from the wash and put them in the dryer.

“I suppose I’m washing the dishes too?”

“I might help,” I said on my way to the laundry room.

When I got back she was already elbows deep in the dish water with her shirt wet. I started rinsing and tried to keep my eyes off of her peekaboo breasts. They weren’t small but not overly large either. About the size of a man’s hand with enough left over to suck on. With her shirt wet I could see her hard nipples underneath as the material clung and stretched. My cock throbbed in my shorts.

“So, what’s after the dishes, Master?” she handed me the last, a purple plastic cup she had drunk coffee from.

Chapter 2

“I haven’t cleaned my room in a while,” I teased.

“Starting to think I should have asked you to do more than my laundry,” she laughed.

“Like wash your car?”

“Yeah, that would have been good,” she grinned.

“We can do that, after we finish with my room,” I shrugged.

“You better fold and put away my clothes too then,” she giggled.

“Why not,” I said.

After we cleaned off the counter and put everything away we headed into my bedroom. I’m like any other teenage male and my room is proof of it; used Kleenex all over the place, magazines and video games scattered everywhere, books tossed around, old homework papers, paper planes, wadded up papers, paper footballs, dog toys here and there, posters on the walls, stuff crammed onto the computer desk, something sticky on the keyboard…

“Gross, you want me to clean this?”

Her voice betrayed her because I could tell she wasn’t really disgusted. Not sure what it was but it wasn’t disgust in her voice as she started collecting used Kleenexes off the floor.

“Damn, how many times a day do you jerk off?” she laughed.

I opened up a garbage bag and dumped the tiny little pail into it before handing it to her to fill up.

“Depends on who is home, sometimes 4 or 5, sometimes 10 or 20,” I shrugged and watched as she bent over again.

“So when you’re hiding in here after school…” she collected another handful of Kleenex.

“Pretty much, that or I’m reading sex stories on the net,” I crammed the old papers off my desk into the garbage bag.

“What kind of stories?” she climbed underneath the desk.

I went to the computer and wiggled the mouse before typing in my password. The last story I wrote popped onto the screen. I was curious what her reaction would be when she read it.

“Like this one,” I stepped back so she could climb back out from under the desk and look.

“My slave sister,” she giggled and started reading as she scrolled the page.

“Oh wow, that’s hot,” she sat down in my chair and pulled it to the desk.

“You don’t think it’s disgusting?”

“Why would I think that?” she gave me a sexy smile before going back to the story.

“Can I look at your favorites? I want to read more,” she clicked on the favorites folder before I even responded.

“Sure, go ahead, I’ll just do your chores while you jerk off,” I used her own line against her.

“Thanks babe, I’ll be done in a minute,” she used my favorite comeback.

“Mom submits, sister cums over, Mom and the dog…wow,” she giggled.

“Who is this MrHappyJohnson?” she asked.

“You really don’t want me to answer that.”

“Matt…”

“I have a vivid imagination alright? It’s me,” I grumbled.

She skimmed over the story summaries, “They’re fucking hot bro, why have you been holding out?”

“Because it’s embarrassing, and I thought you would get mad,” I fell onto the bed.

“Mad? Because my younger brother is a horny little devil with a wicked tongue who writes his fantasies for everyone to read but me and apparently thinks I’m sexy as hell? Hell yeah I’m mad, but not because of what you wrote.” she went back to reading again.

“Are you sure you’re still a virgin?” she asked a minute later.

“Yeah, unfortunately,” I groaned.

“Ok, I have to stop reading these now, but I will finish later. Let’s get back to cleaning,” she hopped from the chair and I noticed Hello Kitty had a wet nose.

We finished picking up my trash and she crawled under the bed, her little ass wiggling along the floor as she dragged everything out. I waited to see what she’d say about my little box of secrets.

“What’s in here?” she asked opening the top of the shoe box.

“Pictures, and stuff” I shrugged.

“No crap, wow these are really good but if I’d known maybe I could have posed a little better,” she giggled.

“And you have some of Mom, and is this one… Kira? Our cousin Kira?” she waved the picture of our blonde haired 20 year old cousin around.

“From that night she slept over, I walked in when she was in the shower,” I shrugged.

“And you just happened to have a camera on you at the time?” she laughed.

“My phone actually, I used the auto printer at Walmart.”

“So that’s what you needed money for,” she grinned.

“So, my little brother is a blogger, an amateur smut writer, a photographer, a panty thief, and a pornographer? I’m impressed and a little jealous.” she laughed.

“Would you model for me?” I asked her.

“I’m your slave for the day remember? I’d do anything you told me to do, but yeah I’d model for you anytime you wanted,” she grinned.

I nodded and filed that away for later as she put everything back into the box and we went back to cleaning.

An hour later she dug out the vacuum cleaner and I went to check on our clothes and took my sheets to the wash. The clothes were dry so I pulled them out and took them into the bedroom so I could fold as she vacuumed.

I set aside what I wanted her to wear to wash her car in, a sexy little G string bikini that I knew barely fit her. Last time she had it on she had to wear a long tank top over it because her ass hung out of the sides and her breasts bulged in the top. This time she wouldn’t be wearing anything over it though. The rest of her clothes I carried into her bedroom where I found Boss sleeping in her bed.

“A little ass and you turn traitor huh?” I chuckled and pulled out her underwear drawer.

It took me a few minutes to put her things away and when I returned I found her sitting at my desk reading with one hand in her Hello Kittys.

“Take them off, I want to watch,” I pulled down my shorts and laid on the bed.

She turned the chair at an angle and slid her panties off. Her eyes went to my hand gripping my dick and she licked her lips. I watched as she pressed a finger into her cream colored pussy and her palm pressed against her clit. I stroked my shaft up and down as her finger pumped in and out.

After about a minute I told her, “Take off your shirt and play with your breasts,” and she quickly obeyed with a sexy moan.

I whistled and a few seconds later Boss came prancing into the room. I snapped my fingers and pointed. He gave me a smug look before going over to Kasey and licking her. She moaned and guided his tongue down to her pussy and pulled her hand away to play with her breasts as he licked her. I stroked harder.

I came hard, squirting jizz on my stomach and thighs while some spilled down my shaft.

“I made a mess, come lick it up,” I grinned and snapped my fingers for Boss to stop.

A few seconds later her velvety tongue slid across my belly and played in my navel before moving down. She licked and sucked every drop of cum from my abs and thighs before taking my dick into her mouth to clean it off too. I groaned and slid my hands to her hair as she sucked and licked.

I grew hard again and she looked up at me.

“Keep sucking it,” I told her and she moaned as her head started bobbing up and down the 6.8 inch shaft.

My hands wandered down her naked body until I reached her pussy and slipped two fingers into her. She moaned around my cock again as I squeezed and pumped. She was soaking wet and made a sexy slurping sound as my fingers slid in and out of her.

“Do you have condoms?” I asked and she groaned as her head shook no.

“Damn, I guess we’ll have to finish each other with our mouths then, climb up so I can taste you.”

She nodded and swung her pussy over my waiting mouth. With the first taste I knew why Boss always had honey scented breath. I pressed my mouth to her and licked like crazy as if she were coated in candy. This time we came together as she hummed around my cock and I fucked her with my fingers and tongue.

She swallowed and kept sucking and bobbing until I slapped her ass and said, “Ok babe, time to get dressed so we can go get wet.”

Chapter 3

She put on the bikini while I pulled on my swim trunks. She pulled her navy blue 2012 Nissan Altima to the back yard. I turned on the water hose and filled a bucket of soapy water.

I gave the car a pre rinse before spraying her and turning the hose off again, took one of the sponges while giving her the second. We started from opposite ends and met in the middle about an hour later for a sponge fight.

After getting each other all soapy and slick we started wrestling around in the grass as I tickled her and she tried to break free. I pinned her down on her stomach with her legs spread and her butt in the air, much like the position she was in when Boss rode her earlier that morning.. She wiggled her butt against my hardon and moaned.

“You keep that up and we’re going to need a condom,” I groaned.

“I’m on the pill,” she whispered.

“Why didn’t you say that earlier?” I tickled her again.

“I wanted to see what you would do,” she said.

I pulled the string on her bottoms and slid them out as I pulled down my shorts.

“I want to fuck you,” I said rubbing my soapy cock up and down her ass cheeks.

“I want you to,” she bucked against me.

That was all I needed and let the head of my dick slip into her warm tight pussy. She was so tight that I had to push hard while pulling her against me. She groaned as I stretched her but thankfully she had already broken her hymen. I slid all the way in before holding her against me.

“Fuck, your tight.”

“And your big,” she moaned.

I let her have a few seconds before I pulled back and pushed into her again. She rolled her ass and I pumped my hips.

“Mmmm, why didn’t we do this sooner?” she moaned and bucked against me.

“Mom and Dad would flip,” I chuckled.

“Not Mom,” she giggled.

I rutted against her like Boss had, my balls slapping against her thighs as my cock pumped into her pussy. Neither of us lasted very long. It was just a few short minutes before my dick erupted inside of her and she started milking me with a muffled scream. I pumped everything I had into her before flipping her over and kissing her mouth. She wrapped her arms and legs around me and my semi hard dick found its way back into her. I reached and untied her top so I could feel her naked body against me..

My dick grew hard again and I started thrusting into her, “I’ve wanted to fuck you for so long.”

“Me too, I just wasn’t sure if you felt the same,” she lifted her hips to press into me.

“I want to do it again, not just today,” I gave her a hard thrust.

“I want to be your slave sister,” she groaned as I went deep.

“Like in the story?” I asked pulling myself out until just the head was left in her.

“Yes, that made me so fucking horny, I want that, exactly that,” she said pulling me deep again.

“A slave for my birthday, the best gift ever!” I shouted and pounded into her until we came a second time.

“What do we do next, Master?” she whispered against my ear a few minutes later.

Chapter 4

“I’ll rinse the car, you can fix us sandwiches for lunch.” I lifted off her and fixed my shorts.

“Naked lunch?”

“You don’t dress unless I give you clothes to wear,” I grinned.

“Mmmm, yes Master,” she moaned.

I collected her bikini and stuffed it in my pocket, it was time to buy her a new one anyway. I grabbed the house and turned it on as I held my thumb over the end and sprayed the car down. As I watched the soapy water wash down the street and held the hose over my head a car pulled into the drive, a sleek red mustang.

Kira emerged from the passenger side, 5’5 with wavy blonde hair to her shoulders dressed in a pair of cut off jeans so short her ass hung out the back and a shirt so tight I could see her 34C breasts, with three burgers, fries, and drinks. A sexy sandy blonde waved from the driver side window as the car backed out again. I reached over and turned off the water before I soaked everything.

“Someone ordered a Bday special,” she grinned and pressed herself against me as I hugged her.

“I told her to fix sandwiches,” I growled.

“Technically she did,” she laughed.

We went inside and into the kitchen. I sat on a bar stool at the counter and Kasey climbed into my lap, still naked, as Kira laid everything out in front of us.

“I’m glad you two finally came to your senses,” she said and took a seat across from us.

“What, you knew?” I frowned.

“Matt, everyone knows, hell you’re always carrying that phone and snapping shots of her ass. And I know you got a few of me in the shower too, I hope you enjoyed the show.” she grinned.

“I did,” I grinned back.

“Did you know he writes sex stories?” Kasey asked her.

“I suspected it was him, MrHappyJohnson right?.”

“You’ve read my stories?”

“Yup, I’m even subscribed so I get new ones in my email.”

“Which one is your favorite?” I asked before taking a bite of my burger.

“They’re all hot and none have me in them, so it’s a little hard to choose. I guess it would be Sis Cums Over.”

“Oh that one was hot, I read them earlier,” Kasey giggled.

“I wrote some about you,” I grinned.

“Really? I haven’t seen them.”

“I’ll show ya after we eat.”

Chapter 4

No one talked again until we had all finished eating and Boss had his share. The four of us went into the bedroom and I loaded up the computer, went to my blog and logged back into my author’s account to bring up the hidden files folder. I clicked on the folder marked MissKitty and then stepped back.

“There’s about ten of them, there short stroke stories but…”

“I’m never around for anything longer than that, I know, I’ll work on that,” she grinned and slipped into my chair to read.

I climbed onto the bed with Kasey and we made out while Boss chewed on his bone and licked his balls.

About ten minutes later we heard a started yelp and my eyes shifted over to where Kira sat. She had taken off her clothes, probably playing with herself and watching us. Boss had climbed up to put his head between her breasts and his cock in her pussy. She had a shocked look on her face as he pumped his cock into her. After a few seconds she started moaning and put her hands around his back, pulling him deeper.

“That’s my pussy Boss,” I growled.

“Let him have his fun, you can have mine all you want,” Kasey reached down to slide my hardon back into her.

I watched Boss fuck our cousin and pumped my dick as fast as I could in Kasey’s snug little pussy. Boss came first and walked away with a smug look on his face. I gave Kasey one last thrust before I pulled out and moved off the bed.

“My pussy,” I growled and jerked Kira and the chair around before jamming my thick cock into her.

She gave another startled yelp and then groaned as I stuffed her. She kissed me and put her hands on my ass as she pulled me into her. I heard Kasey moaning as Boss licked her pussy and grinned as I pounded into Kira twice as hard.

“Cum on me, on my stomach and tits,” she told me.

“Cousin Cums Over?” I chuckled and gave another hard pounding before I pulled out and stroked myself off over her.

She moaned as the hot liquid squirted onto her flesh and smeared it around with her fingers.

“Look Kasey, I made another mess, come clean it up,” I grinned.

“Yes, Master,” Kasey smiled and moved away from Boss to lick my cum from Kira’s pussy, stomach, and breasts.

“Oh fuck, that feels good,” Kira said as Kasey licked her clit.

Kasey had her butt wagging provocatively and Boss took full advantage, stuffing her perky asshole with his dick and latching onto her shoulders. Kira gave me a “come hither” and I took the few steps to stand beside her. She leaned over and sucked my soft dick into her mouth like a vacuum cleaner.

“I love sucking dick while it’s soft, then as it grows in my mouth,” she said around my semi hard dick.

She sucked me back in and I felt her tongue roll over me as her hand gripped and played with my balls. By the time Boss had finished his Knot my dick was ready for action and Kasey’s asshole was already open and lubricated. I slid in with a tight fit that made her groan.

“This is so fucking hot, you should have called me earlier,” Kira said as she watched and played with her breasts.

I fucked Kasey’s ass for a few minutes but I didn’t cum, not yet. I had the girls switch places so that Kira was eating Kasey’s pussy and I mounted Kira from behind. Boss looked jealous and Kasey kissed her lips together. Boss padded over to her and she reached down to jerk him off. I pulled out after a few minutes and snapped my fingers before slapping my hand against Kira’s ass cheeks.

Boss padded over and mounted her ass. I walked to slap my cock against Kasey’s lips. A couple of minutes later me and Boss came and I shot my load all over Kasey and Kira before telling them to clean each other off. Then I walked Boss out to the back with his favorite tennis ball wrapped in a pair of Hello Kitty panties.

About twenty minutes later Kira’s ride came to pick her up for work and Kasey joined me on the back porch, “What next, Master?”
