Brother Deals with Sister

8000 words, so not a short story. There is no hardcore force or rape. Just some reluctance.

"I have a proposition for you Kelly."

My sister looked at me and frowned. We were both slumped on the couch watching mindless crap on the TV. Mum and dad were at work and we were left pretty much alone for most of the day during the summer holidays.

We were both on break from school, but mum and dad had decided we had to do plenty of chores around the house. Something about the devil being in idle hands. Not that we were religious, my dad just like the expression because it let him order us about.

So we had to stay around the house and work several hours a day to complete the chores before the parents got home and give us an earful. It meant we couldn't catch the bus or train into the city.

I wasn't affected. I didn't have any friends to hang out with. I had friends at school, but we were a bunch of guys who hung out with each other, just so we wouldn't be loners. We weren't the loser group, but we weren't far off.

So I was planning to study, play games and relax the holidays away, but I knew my sister would be wanting to leave home. We went to different schools, but I knew she was much more popular than me.

That was where my proposition hinged.

We were twins, but only because we were born the same day, there was no comparison in looks. She was petite, brunette with lightly tanned skin. Kelly had enough curves that every man checked her out when they saw her. Even me, well especially me.

I was just a regular guy, any one of billions. Brown hair, pale skin, medium build. That was me. I think Kelly got all the good genes while I picked up the average ones.

Kelly looked curiously at me. Her being bored would only play into my hands.

"What is it?"

I sat up, crossed my legs on the couched and pushed my hands together. Kelly rolled her eyes.

"I am shit with the ladies. Like I barely register on their radar. So I have needs that need to be met with no possibility anything happening."

"Yeah you are a loser, you couldn't catch any pussy if a cat was thrown at you."

Kelly's analogy nearly made me laugh. I cleared my throat.

"Exactly. So here is my offer." Kelly narrowed her eyes and sat up properly. "You want to go into the city don't you? You don't want to be stuck out here all summer with just me for company."

"Uh, yeah."

"Because of those chores mum and dad want from us, you can't catch the early train in. What I am offering is to do your chores for certain services from you."

Kelly stared at me, her face slowly moving into a deep scowl.

"What the fuck! Are you trying to buy me?"

I tilted my head. I needed to stay calm and let her see the benefits. I couldn't wimp out now.

"Yes. I do your chores and you let me fuck you whenever I want when you are home. I will pretend that you did the chores and you still get the money mum and dad pay for them. Win win for you."

"No freaking way. You are my brother, my twin brother! I'm not going to let you fuck me or even touch me! If you don't shut up right now and stay the hell out of my sight for the rest of summer I am going to tell mum and dad. In fact you will do my chores just so I don't tell."

I smiled and spread my hands.

"So you say to mum and dad I offered to do your chores for sex? Where is your proof and are they likely to believe you when they know me so well? They know I am the top student of the school and even do community service down at the local mental asylum."

People always got freaked out when I told them that. They didn't realise most people at the asylum were perfectly fine and none of them were criminally insane. The worst I faced was having to listen to delusions for hours on end. Though the person was usually so passionate you found yourself caught up. It was like listening to an audio fantasy book.

Only the doctors, nurses and interns copped crap. To the people in the asylum I was just another one of them who visited on weekends. And as such was an ally and friend.

Of course no one knew I had taken the community service to add to my squeaky clean reputation. I enjoyed the work, but I was getting so much more out of it.

I had been planning this 'proposition' for a long time. My sister's body was way too hot and tight for me to ignore.

Kelly stared at me. I continued.

"You may be a top student as well, but you used a lie a lot when you were a kid remember?"

Kelly snorted. She was already a little calmer. I just needed to keep this like a business deal.

"Maybe when I ten or something. But that was way back then, mum will believe me."

I smirked.

"Parents. How do mum and dad treat you now even though you are no longer a child?" Kelly opened her mouth and a little bit of doubt entered her scowl. "Exactly, they still think of us as kids. To them we are still their little babies."

Kelly flinched. Mum still called us her little babies and I was glad I never had any friends around to here that. I know Kelly hates it as much as me.

"I am not going to let you fuck me. I can't let my brother be my... I can't let you fuck me."

I spread my hands.

"Come on. You know me. I would barely last twenty seconds before cumming. You'd barely feel my tiny cock. You'd only have to deal with me a short time every day. Meanwhile I will do your chores while you mess with your friends in the city."

I desperately hoped I was lying. I had never been with a girl, so how was I to know how long I would last. But I needed to sell the negatives of the deal as taking barely any time.

"I don't have friends to mess with."

"I don't mean guys. Girl friends."

Kelly stared at me like I was an idiot. I had missed something, but that didn't matter now. Kelly wouldn't be able to spend all summer here with me. Her reputation would probably die. I imagined she was the type of popular chick near the top of the social totem pole. She certainly had the looks to be the most popular, hell she could be a model in any magazine she wanted.

Kelly got up and looked at the clock.

"I have to go and clean the pool."

Kelly pushed off the couch and swayed away, not on purpose, but her arse swayed gracefully no matter how she walked. I watched and didn't even bother to raise my eyes until she had turned around, and then I only raised them to her pert breasts.

Kelly made a disgusted noise and went up stairs to change. I quickly followed her up to change into my swimming trunks and beat her to the pool in the back yard.

Our pool was quite large, while thanks to our large back yard we still managed to have a large square of grass to mow. And plenty of garden beds to weed and look after the plants. All in all I bet dad was glad me and Kelly were home to take care of the high maintenance back garden.

I turned the entertainment system on in the patio and nodded my head along with Depeche Mode's Wrong. Kelly strutted in just as the chorus pumped out.

"What are you doing?"

"I thought I would help you with the pool. Seems fair for you listening to my proposal. You can give me an answer tomorrow, even if you say no the offer will stay open all summer. Just see how long you can last."

Kelly looked around. We had high fences all around the yard and the neighbours all worked the same hours as mum and dad. The suburb was practically empty, but Kelly still kept her voice low. Not that I was being any less cautious with my vaguely worded statement.

"Oh I won't be changing my mind any time soon."

Kelly started to get things organised while I jumped in the pool with a broom. Dad told us he wanted the sides and bottom as clean as possible. Since the machine only did the bottom and even then not up to his standards we had to scrub with brooms. There wasn't much to clean, but because of the crappy city water we used the yucky green algae stuff formed pretty fast. Even the chlorine in the water wouldn't stop it.

It wasn't noticable until you touched the wall or bottom or didn't clean it properly once a week.

So we scrubbed the walls and dived down to the bottom to scrub the thin layer of crap off while the machines sucked the crap in.

We were having a break from what was one of the worst weekly tasks when I started my sales spiel again.

"You know you don't have to do it all at once. We can go by steps."

"What are you talking about now? I can't believe I never noticed how deranged you were. I thought you were a goody two shoes."

"All carefully maintained to ensure no one would believe you when I offered you this deal. Now say I take over your chore of dusting."

We both did all the same chores, most had to be done at least three times a week, some more. Dusting was an every day chore.

"What so you would take a chore at a time and get more and more off me?"

"Remember you still get the money they pay you, but yes. If I take over your dusting duties I might ask for..."

Kelly interrupted me.

"Why would that help me except to give me some free time to my already empty schedule. Dusting is daily, but that wouldn't allow me to go into the city."

I paused.

"You have a point, but I was only using it as a demonstration. If I took over your dusting. I would be allowed to say." I pretended to think, but I had already worked out a compensation table for the chores. "I would be able to kiss you, with tongue any time I wanted."

Kelly made a face and pushed off the pool edge.

"I thought you just wanted one thing. Not something intimate like kissing."

She sounded surprised by the apparently mild request. And she considered kissing more intimate than sex, in one way it was.

"Oh no dear sister. I want all of you. That means I want to be able to touch you everywhere when ever I want and do what ever I want to you. But if you are only comfortable with a few things then I am fine with that. I won't black mail you or force you to do anything. You are in control."

Kelly frowned and dived down to the bottom of the pool to scrub. It was hard to get any purchase to scrub hard. I enjoyed watching her flailing legs and tight arse before going back to work.

I would work on her until she gave up one piece of her self at a time.

A week later.

The summer holidays stretched out into infinity as once again me and Kelly lay on the couch. With nothing to do each day seemed to last forever.

I hadn't let a day pass by or let Kelly do a chore without extending my offer again and again. I knew she was getting close to giving in on some chores. Even I was getting itchy from staying at home so much. When we were at school, home was only there to come home to and sleep before another day of school.

Some of our chores were down right nasty, like turning over the compost heap so the fresh scraps were pushed inside. The rancid remains of the previous lot of scraps almost made me throw up and the smell got worse when you turned the heap. Kelly had that chore today.

"What would you ask for if you did the compost heap?"

I smiled and pretended to think.

"I would be allowed to touch your arse in any way I wanted any time I want from now on."

Kelly frowned.

"Only my arse, not my puss.. Not anything else? Just my arse?"

I nodded.

"You have my guarantee. I mean my hand might slip or something, but if I do touch your pussy by accident I give up the right to touch your arse for that day. So that will ensure I don't do it on purpose."

Kelly stared hard at the floor before nodding. I had to restrain myself from jumping for joy.

"Ok, but you have to go and do the compost first, then shower, twice."

I nodded.

"Ok, but I need to make sure our deal is binding. I don't want you to back out after I touch your arse just once. So we have to twin promise."

Kelly frowned. A twin promise was from we were young and trying to be like those freaky twins you see in films. We were just normal people with no telepathy or secret language. But the twin promise was still deeply binding to both of us.

Kelly finally nodded. She stood up and I stood right in front of her. We clasped hands and stepped close to rub our noses and breath in each others breath.

"By my twin I swear to let you touch my arse any time you want as long as you take over the compost chore for the summer."

"By my twin I swear to take on the compost chore in return for your sweet arse."

We pursed our lips and pushed them against other. It wasn't a kiss, just our lips touching. I had to restrain myself from trying to pash her right there and then, but I couldn't ruin it.

We separated and Kelly sat down with a slightly worried face. I nodded and went into the backyard, right to the back corner, where our next door neighbour kept his compost heap as well.

It took me an hour to turn the heap, which was full of rotting vegetables and meat people weren't supposed to put in, but did. I managed to keep from throwing up for the first twenty minutes.

I returned inside with a sore throat and stomach from retching and quickly took a shower. Then completely soaping myself up for the second time. I needed Kelly to not retch at my smell if possible. My cock was already hard.

I went downstairs to find Kelly sitting on the couch. I grinned at her and she rolled her eyes, she looked nervous.

"Ok, take off your pants and lay belly down on the couch."

"What! I said you could touch my arse, but not..."

Kelly trailed off as she realised I had never mentioned anything about clothing. She would be protesting again in a minute when I started on her.

Kelly glared at me, stood up and ripped down her pants. She was wearing pale blue panties. Something about her being half naked, just made me go wild. My cock twitched hard in my pants as I moved over to her. She was still standing up, crossing her arms beneath her breasts and looking very uncomfortable.

I reached around, careful not to push my erection against her and cupped her soft cheeks. She flinched at the contact as I started to massage her perfect arse.

"You don't want to stand up all day do you?" Kelly huffed and moved over to the couch. She quickly lay down, her legs pressed tightly together. "Better. If you relax a bit you might find you enjoy having your arse played with."

Kelly grunted as I kneeled on the floor so my face was close to her arse.

I started off with just cupping and squeezing her meaty globes through her panties. Softly tickling her and pinching her soft, oh so soft cheeks. Her muscles had started to relax at the gentle assault.

I leaned over and made sure she felt my hot breath on her cheeks, before popping my mouth on a piece of exposed arse cheek and sucking.

She groaned in disgust or annoyance. I wasn't sure. But she didn't protest as I sucked her arse cheek. I let it go with a pop and licked my tongue up and down her arse not covered by panties. I stopped just below where her arse met her thighs.

I kept this up till she was relaxing again. Then I grabbed the band of her panties and started to pull them down. Her hand shot out and grabbed my wrist. She didn't say anything.

"You said I could touch your arse and this is what I am going to do."

"But you'll be able to see my pussy." Her voice was soft. "That wasn't part of the deal."

I frowned. She might try to wriggle out the deal with this, or at least limit me somehow.

"Ok, remember I offered to dust in return for kisses?" Kelly nodded. "Well I still expect to be able to kiss you, but in exchange for letting me see your pussy. I will also give you five chances each day to cancel my privileges. Each time you rebuff me, I can't try again for half an hour."

"Make it an hour and I'll agree. Each chance cancels all privileges."

I frowned. Even if she timed it right and stopped me for five hours, we spent over eight hours home alone. Besides I would need to do all these chores and I could use those hours, knowing they weren't wasted.

"Deal, but you can't use it today. I will give you five go to jail cards from monopoly tonight." We had three or four sets so I had enough cards. "Now time to enjoy my sister's arse."

Kelly let go and I pulled her panties down, I paused and pulled them all the way down her legs. I moved up to her face and pressed my lips against her own. She reluctantly opened her mouth and my tongue invaded.

I didn't go all out straight away. I only had one kiss under my belt and that had been off a girl in school years ago who wanted to see what it was like. So I only pushed my tongue in a short way to play with her lips and the tip of her tongue.

I regretted not making her have to kiss me back, but it was too late for that now. I mashed my lips against hers in a slow massage while rubbing her arse with my right hand. Her lips were amazingly soft and face felt impossibly smooth against my own

I nearly jerked back in surprise as I felt Kelly's tongue finally move and start to play with my own. We both gently encircled each other's tongues before pressing deeper into each other's mouth. I moaned softly, kissing my sister was hot, but her kissing me back was ten times as freaking hot.

I pulled back from the kiss reluctantly, Kelly's mouth stayed open for a bit before she realised I was finished. Her eyes flashed at me.

"I only kissed back because of our deal. Don't go thinking anything."

I nodded as if that was true and moved back to her arse. I was done with being subtle. I spread her cheeks and looked along her crack to her rosebud. Kelly wriggled uncomfortably, but didn't do anything else.

I ran my tongue along her crack before swirling it around her rosebud. Kelly softly squealed.

"That tickles."

I grinned and moved up onto the couch, pushing her legs wider so I could lay between them. I pressed my face into her arse, licking up and down her crack, getting it wet. Then started to work on her rosebud. Swirling my tongue all over her faintly tasting hole. She must have washed well, because I could barely taste anything.

That didn't last long as I shoved my tongue inside, I couldn't get it very deep. Kelly moaned in surprised and I felt her rise up onto her elbows to look back at me.

"Only your tongue, no fingers and definitely not that." I nodded and she watched me continue to lick and stab with my tongue. "I don't have enough chores for you to take to let you fuck me there."

I tasted her arse fully now. Slightly bitter, savoury and a bit sharp. But to me she tasted delicious. I went mad with my tongue, I didn't even pause as Kelly pushed her arse back onto my tongue.

I pulled my face away from her arse breathlessly. My tongue and jaw were sore from the activity. Kelly groaned slightly and I squeezed her arse.

"Now time for the main event."

Kelly looked around suspiciously as I started to take off my pants.

"I said you couldn't.."

I held up my hand.

"And I won't, but you didn't say I couldn't touch you with my dick."

She stared as hard cock flicked out of my pants to thwack against my belly. She blinked and licked her lips nervously.

"You said you were tiny."

I looked down.

"I was obviously lying to you. I am probably average. Haven't you seem a cock before?"

Kelly shook her head. I was surprised, I thought she had had boyfriends. I mean she never told me and I never saw or heard about them. But she is an intensely beautiful young woman, how could the guys leave her alone?

Kelly watched as I leaned down and placed my cock in her wet crack. Her arse was quite small so it had been easy for me to tongue her hole, but that also meant I wasn't enveloped in arse meat. Not that I was complaining. I thought her face was smooth, but her arse on my cock felt like the highest quality silk.

I moaned in pleasure as I glided my cock up and down her crack. Her pert cheeks grabbing at the side of my cock and increasing the pleasure tenfold.

Kelly looked back me with a half disgusted half fascinated look on her face. I moved my face next to hers and went to kiss her as I humped her arse. She pulled back in disgust.

"No way, you just had your tongue up my arse. I'm not kissing you now, that is gross."

She looked half scared I would force her and she would have to allow me. But that wasn't what I was after. I shrugged and looked into her eyes as I fucked her arse cheeks.

"You didn't think it was gross when my tongue was up your arse."

Kelly flushed and looked away. I pulled back and really started to thrust my hips. I had been watching Kelly like a hawk for the last week, looking for signs of her giving in. I had pretty much been hard the whole time as her pert and supple body bounced around. I swear she had been teasing me.

I grunted in time to my thrusts, her smooth and tight arse cheeks clenching my cock. I didn't know if it was my imagination but her arse seemed tighter than I had started. I knew she didn't like this to react like that, yet.

I groaned as I felt my balls tighten, I grabbed my cock and started to wank furiously. I groaned deeply as cum squirted out of my dick and splashed against Kelly's arse cheek. She had turned around at my groan and watched fascinated as I came on her arse.

I squirted another two ropes of cum onto her arse cheeks and dribbled a little more onto her rosebud. I rubbed the head of my cock on her hole and groaned at the extra pleasure before my cock softened.

I looked at my handy work and grinned. Kelly sighed and raised her eyebrows.

"Are you going to do this every day?"

I shrugged and wiped the last of my cum off on her arse cheek before putting my cock away.

"Depends how soon you want me to take another of your chores."

Kelly got up and started quickly for the bathroom. I followed to make sure none of my cum dripped off her arse. I stared at her pussy poking out between her legs. In my lust for her arse I had neglected to look at her pussy closely. From what I could see it was tight and puffy looking. So tasty I knew I had to speed up our progress.

A few days of enjoying Kelly's arse had made me impatient for more. Things were progressing and if I was honest with myself they were happening faster than I had dared to hope.

Kelly didn't flinch any more when I groped her arse and she would only giggle when I pushed my hand down her pants and played with her arse. Even when I was rubbing her rosebud and softly pushing she only cooed and looked at me with an amused grin.

If I didn't know her better I would say she was getting into it

I watched Kelly clean my cum from her arse again, inspecting it between her fingertips. I had the strangest feeling she would have tasted it if I wasn't there. But I dismissed the thought. She wasn't a deviant like her twin brother.

"So I'll wash the cars in return for breasts, belly and back privileges. All three cars."

Both mum and dad had cars which were straight forward to wash. But the third was a vintage sports coupe mum and dad took to classic car gatherings and Sunday drives. It was a pain in the neck as you had to wash, wax and polish. Each bloody time.

Kelly wiped her arse clean with a wet wash cloth, making sure to get in her crack and clean my cum off her rosebud. Just thinking about it made me hard again.

I held my breath as I waited for her respond. Maybe she was weirded out by me humping and cumming on her arse and didn't want any more even if I took annoying chores.

Kelly placed her hands on the edge of the sink and looked back at me. I could see her thinking through the deals.

"My go to jail cards cover everything right? And you had better do a good job with the coup. If you mess up you have to own up and say we switched turns. And when you are fucking my breasts doesn't mean you can cum on my face. That will cost you vacuuming."

I stared at Kelly and she winked.

"Two can play this game. You are my little brother." She was older, just. "So having you play with my body doesn't really mean much. Like a little baby with its mother."

"Hang on. The house is massive, I reckon I should be able to get blowjobs for that."

Kelly lifted up her shirt, chucked it on the floor and moved closer to me. I watched her in only her bra walk towards me. Her tight body on full display, her sexy smooth belly and medium sized breasts jutted out perfectly. Her tasty looking pussy, topped only by a small strip of pubic hair, her tight lips looking even better than usual.

Her hands went behind her back and her breasts jiggled slightly as they were released. Her bra was thrown on the floor and I finally saw those perky goodies. They sat straight out from her chest, her small pink pointy nipples looking like they needed to be licked.

Kelly pushed her chest against me and looped her arms around my neck. She pouted and leaned in close.

"Come on vacuum the house and you get to come on my face."

Kelly suddenly moved forward and pushed her lips against mine and started to kiss me deep. This was the first time she had kissed me after I rimmed her arse. Usually I had to use mouth wash before she would kiss me. I felt her left lift up and rest on my waist and pull me in tight, my hands had gone straight to her arse, but now my left hand was rubbing up and down her back. Kelly pulled back and I breathlessly stared at her.

"Come on say deal."

She humped against me and I choked out that one word.

"Deal."

Kelly smiled and stepped back. She had won one over me. But she still had enough chores I knew I could get her to fuck me. I blinked. She had made me agree to cum on her face. But she had done it so she didn't have to blow me. The lesser of two evils.

Kelly leaned down right in front of me and I watched as she pulled my pants down, freeing my hard member. She grabbed it and kneeled up straighter to push it between her breasts. I groaned as my cock touched her sweet soft breasts.

I immediately started to jack hammer my cock between her breasts. Kelly giggled as my cock kept on popping out. She pushed her breasts together with one hand and her elbow, using her free hand to trap my cock inside. I moaned and watched her breasts jiggle slightly from my assault.

Kelly was watching my cock intently as it slid up and down between her perky breasts. While she wasn't overflowing with breasts like some women, Kelly had more than enough to make my dick feel like it was melting in pleasure.

I grunted and that was all the warning Kelly got before I shoved my dick as hard as I could into her breasts. The tip directly facing her watching face.

I groaned deeply as the first shot fired into her face. She jumped as my hot cum splattered over her cute nose, the second squirt hit her open mouth perfectly. I moaned and kept humping into her breasts as I dribbled a the dregs of my orgasm on Kelly's tits.

Kelly coughed a little and looked up at me with a smile on her face and a white dripping nose. She stood up and opened her mouth to show me the cum inside. She swallowed audibly and swirled her tongue around her mouth to catch the cum dripping down.

"Ok I'll let you cum in my mouth as well, but only because you are so tasty."

I watched open mouthed as Kelly collected the rest of my cum with her finger and sucked it into her mouth. She washed her face and breasts in the basin, the swayed out of the bathroom completely naked.

I shook my head and looked in the mirror. I had a massive grin on my face, stretching my cheeks. Oh yes this was going better than I thought.

The next few days I pestered Kelly constantly. She had to use her go to jail card to make me do my chores before mum and dad came home. I was so horny and once again wanted to step up our deals.

I only had mowing the lawn, looking after the garden (front and back) and washing the dishes left to trade with. The dishes would be a little hard because I needed mum and dad to think Kelly was doing all her chores. And since they were only a room away, it would be hard to pretend Kelly did them when she was elsewhere.

I wasn't quite so sure I had enough to get my sister to fuck me. I knew she would let me play with her pussy for one chore. But she would seduce me again and probably get the other two chores to let me finger her and blowjobs if I was lucky.

She knew just how to get me, I knew she wouldn't mind rubbing against me as long as it got her easier deals.

I finally finished dusting the whole house, along with vacuuming and cleaning the pool all by myself. Kelly swimming around in a bikini didn't help.

I sighed and eased myself down onto the couch, my legs were killing me and for once I didn't have the energy to harass Kelly.

Kelly walked into the room and plopped into lap, I grunted as her tight arse landed on my hard aching cock. I rested one hand on her bare belly under her shirt and slipped the other through the arm hole to grope her breasts through her bra.

Kelly sighed and wiggled her arse on my cock.

"So I was thinking. Mowing the lawns is such a drag. I think..."

Kelly got up and pulled my pants down, she pulled hers down as well and sat on my cock. I grunted in pleasure as her pussy pushed onto my cock. I quickly moved to slide it between her cheeks before she used her right to stop all fun today because I touched her pussy.

Kelly swatted my hands away and rubbed her pussy on my cock. I groaned again. Her tight and moist lips rubbed up and down my cock. So tight her pussy was almost nibbling at my cock.

"I think you will mow both lawns in return for touching my pussy. Just touching, though I will allow you to finger and lick me as much as you want. Deal."

"Deal."

I groaned I was in heaven. She could have added all the other chores and I would have agreed.

"Just remember to tell me when you are about to cum."

Kelly pulled off her top and bra so she was naked and turned to straddle my lap. She sat up and rubbed my cock head up and down her pussy. I wanted so bad to thrust up and fuck my cock inside my sister's sweet tight pussy.

But just before I humped up Kelly pushed my cock down and rubbed her pussy up and down my length. I groaned and looked down in surprise as I felt my cock get wetter and wetter. Kelly pulled my chin up and shoved her tongue in my mouth.

I was too surprised to respond for a moment then I grabbed her arse and rubbed my finger on her rosebud. Her juices had leaked onto her arse and I took advantage. I couldn't believe she was getting off on me.

I slowly pushed my index finger into Kelly's arse and she moaned into my mouth. One hand held her arse cheek open, while the other fingered her tight hole.

By the time I added another finger her hips were a blur on my cock, now covered in a liberal coating of girl juices. I wasn't so much fingering her arse, but holding my hand steady for her to fuck back one. I was getting hotter from how much she was turned on. I pulled away from the kiss and started to suck on her breasts. Kelly gave a long low groan and started to cum on my cock sliding up between her pussy lips.

"Oh god yes this is good."

I couldn't help it, Kelly's pussy felt too good, her slick juices making our humping fast and hot.

"Gonna cum!"

Kelly quickly jumped off and started jacking my cock while aiming it in her mouth. Her lips so close they were nearly touching my cock.

"Come on and give me some tasty cum."

That one sentence pushed me over the edge and I started to cum. My cock pulsing with each shoot of spunk firing into Kelly's mouth. I groaned as I finished. My whole body twitched as Kelly flicked her tongue out to lash the end of my cock and get the last drop from my cock.

I looked down at her as she swallowed my load. She was looking at my cock almost like she was drunk. She looked back at me.

"Gardens at the front get you a blow job."

I gasped as her hot mouth enveloped my softening cock. I shuddered and groaned.

"Deal."

Kelly rubbed my balls with one hand, while the other was rubbing her pussy while she sucked the head and first few inches of my cock. I groaned as I quickly hardened in her mouth. She was sucking hard at my cock and moving her head up and down, but she was awkward.

I suppose she hadn't blown many guys. The gears in my head clicked, having been frozen from an overload of lust and I looked down at Kelly. I didn't want to interrupt her blow job, but I needed to know.

After all she had plenty of chances to go to the city because I had taken her chores but she hadn't.

"You aren't popular at school are you?" Kelly looked up and raised an eyebrow as she gave an extra hard suck. "I mean I always assumed because you were so beautiful you were popular."

Kelly pulled my dick from her mouth with a pop and slowly licked up and down as she jacked my cock. She interrupted her talking with licking.

"I never fit in with the skinny dumb bitches who would bend over for an old fart if they thought they could cum or get something. And while the guys would hit on me I just told them to fuck off. Before I knew it, I was hanging out in the library waiting for school to end."

I groaned as Kelly gave me one last suck and stood up. I knew what she was going to say.

"Deal."

Kelly smiled and straddled my legs again, her pussy once again holding my cock head right near her entrance.

"Gardens at the back get you a hot fuck whenever I want it."

I groaned as Kelly slowly started to lower herself down. She hit her lip as my cock head split her lips and pushed her entrance open. She gave a small grunt as my cock head popped into her pussy.

"You know I had a funny feeling my first cock would be my brothers. Now don't move until I tell you."

Kelly took a deep breath and slammed her hips down so her pussy swallowed up my cock in one go. She grunted in pain while I gasped and struggled to stop from cumming as her tight walls clenched at me. Kelly wrapped her arms around me and pulled my mouth onto hers. I kissed her back softly as she shuddered on my cock, trying to get used to my hard member in her virgin pussy. She would grunt and groan as her pussy pulsed around my dick

After a few moments I returned my index and middle finger to her arse, fingering her slowly. She moaned into my mouth and pulled my other hand up to grab her breasts. We stayed like that for I don't know how long, but soon Kelly started to shift her hips while I was impaling her.

I tried to hold out for as long as I could, but she felt too good. I started to hump up into her, making her moan with every thrust. I couldn't pull out much because she was sitting on me, but it felt great.

I fell sideways and rolled Kelly onto her back. We broke the kiss and my gorgeous sister looked up at me, her face flushed deep red.

I kept fingering her arse, even with the awkward position and started to thrust in and out of her properly. Kelly was moaning and looking up at me with bright eyes.

"Come inside of me. I want to feel you fill me up with your spunk."

My sister's word tripped a flag in my head and I started to fuck her hard and fast. Her constant moaning was interrupted every time I thrust inside as hard as I could, making her breasts jiggle.

I pulled my fingers from her arse and shoved them inside her mouth, Kelly sucked hard on my fingers. I didn't pull them out until her swirling tongue had cleaned them thoroughly.

I grabbed her hips and started to pummel my cock in and out of her recently virgin pussy. Kelly was moaning deeply and playing with her clit.

I slammed into her a few more times until I was deep as I could go and started cum. Threads of spunk shot into my sister's pussy and I groaned with each shot. I humped her quickly as I rode out my orgasm, pushing my cum even deeper into her pussy. While I was cumming, Kelly's hot and tight pussy got even tighter as she clamped up and began groaning deeply.

I shot one last wad of cum into Kelly's pussy and half collapsed on top of her. Her arms encircled me and she licked my ear.

"Now I wonder what you get for doing the dishes for me." My cock instantly hardened from half soft and Kelly giggled, but she pushed me out of her pussy. "No more today, I need to rest that part."

I nodded. I imagined while she had cum, she had still felt quite a lot of pain and that wasn't going to go away straight away.

Epilogue.

I pushed my hands into the sink and pulled out the last few utensils and gave them a quick wash before drying them and putting them away. Kelly was sitting at the kitchen table, ready to jump up and pretend to be doing the dishes while the parents were in the lounge.

They were getting ready to go out, while me and Kelly were getting ready to go all out once they left.

The last week I had been on cloud nine. After I first fucked Kelly I had expected some days before we fucked again. But that night she had slipped into my bed for some slow love making and that was what it was. We were gentle with each other, trying to give the other the most amount of pleasure.

Then once we had cum, we fucked each other like animals. I was glad my bedroom was two rooms from our parents.

Kelly still loved me to lick her arse and I had spent a lot of time each day licking and fingering her arse. Of course I spent much longer doing all of my chores plus Kelly's. Only the fact I knew I was going to get a blow job or sex was keeping me going. Though Kelly helped me with cleaning the pool. Or she would pose in sexy outfits while I dusted or vacuumed.

Mum and dad bid us goodbye, going to some retro 1920's gangster ball. Dad actually looked pretty cool in a fedora and sharp suit, while mum looked classy in her gown. I always liked the 1920's, though I suspected the gangsters hadn't actually gone 'now see here, meh' like in the movies.

As soon as they were gone we both moved to the lounge, first making sure they hadn't left anything behind that would make them return. I made sure to lock the door and close all the blinds.

By the time I had finished Kelly was naked on her hands and knees in front of the couch. I swallowed at the sight, she was so fucking hot and I had her to myself.

I quickly chucked off my clothes and kneeled behind her, shoving my face into her arse and making her laugh.

"It tickles but damn it feels good. Get me nice and wet."

I played with her pussy as I rimmed her arse, sliding a finger in once she was wet enough. Before long I had three fingers stretching her amazingly tight pussy. I moved my face away and started to finger her arse, starting with one and quickly moving to three.

Kelly moaned, pushing her arse back on my fingers as I slowly fingered both holes.

"I think it's time."

I nodded and pulled the tube of lube from my pants on the ground near by. I slid my cock in Kelly's pussy in one smooth thrust as I quickly lubed up her arse. I pulled out and lubed up my cock.

I took a deep breath. I was about to fuck my sister in the arse. I placed my cock at her rosebud, it was still tight looking despite the stretching I had been doing for the past week.

I pushed and gritted my teeth as my sensitive cock was swallowed up by Kelly's tight arse. She huffed and moaned in equal measure as I slowly plunged my hard member into her depths. Her soft cheeks pushed against my hips, I thrust a little harder and pushed a little deeper in before slowly pulling out. I repeated the slow thrusts for a few minutes.

Kelly was moaning now and I knew that was enough of a slow fuck. Every thrust in I got faster and faster, Kelly's tight arse clenching at my cock. Trying to milk a load out of me.

Her arse felt too great and I knew I wouldn't last long. I started to pound her arse, making her huff and her tight arse jiggle a little bit.

I leant over her and grabbed both breasts, thrusting as hard and fast as I could into Kelly's arse.

"Ohhh yeah, fuck me hard brother. Don't hold back because you'll be putting more than one load up my arse tonight. Then you have to fill my pussy, it is only fair."

I grunted as my cock slid in and out of Kelly's slick and smooth arse while her tight ring clenched along my own length.

I moaned deeply and began to shoot my cum inside Kelly's arse. Her own orgasm was making her whole body clench, giving us both more pleasure as my cock filled up her arse.

Kelly was cumming so hard her tongue was nearly hanging out as she moaned constantly on my dick in her arse. Her hands was rubbing like mad on her clit and I was still squirting my load deep in her arse.

I sucked on Kelly's neck and slowly pulled out of her arse to collapse on the couch. Kelly turned around and crawled between my legs to suck my cock into her mouth. She slurped up and down the length and smiled at me.

"Don't think we have finished yet."

The End.
