Your Fault Ch. 03

"Oh quit whining and get that fat ass on my cock. Come on, ride me. You wanna get fucked so bad? You do it." Haley challenged, trying not to smile as Alex's eyes lit up as she quickly crawl towards her. Then she ordered, "No stop! Turn around. Mmmmmm, I wanna see those big tits of yours bounce as you ride me. That's it, good girl."

Alex glared at Haley, but didn't hesitate to turn herself around so she was face to face with her older sister/the woman she loved as she climbed onto her lap and lined up her butt hole with the head of Haley's cock.

Luckily her back hole was still slightly open, it and then her back passage welcoming the dildo easily back inside it when she started lowering herself downwards.

Part of her wanted to just drop down all the way on the big cock and then start riding it with every ounce of her strength, but from the look in her eye Haley didn't want her to do that, either for her own benefit or out of a sense of looking after Alex's welfare. To be fair doing that would have hurt, but it was the type of pain a sadistic part of Alex very much enjoyed.

However even though she had enjoyed the initial pain, and the incredible feeling pleasure that followed it, Alex was glad for that look as it gave her the chance to savour the feeling of once again being anally penetrated and then having a big strap-on sliding in and out of her most private hole and making her feel like what she was, a big slut. Her sister's slut. Haley's anal slut.

Oh yes, for all her intellect Alex was once again reduced to nothing but her own sister's shameless anal slut, the reality of that helping her rectum to loosen until she felt nothing but pleasure even as she increased the pace of her bouncing. She was then of course punished for it with a hard slap to one of her meaty cheeks.

"Bad girl! That's a very bad girl!" Haley scolded while delivering a few more hard blows to that fat butt cheek, "I said you can ride me, not that you can make yourself cum. Mmmmmm, I want to enjoy watching these big boobs bounce in front of me before I let you do that."

As she said that last part Haley sat up, reached up and gently grabbed Alex's big titties with just the right amount of pressure to make the younger brunette moan happily. Well, maybe it was slightly rougher than perfect, but that was clearly deliberate, and the ever so slightly harder grabbing just made it feel better than if it was perfect.

Unsurprisingly Haley didn't remove her hands when she made her point and continued shamelessly groping them as Alex reluctantly slowed herself down to a gentle rhythm, which still felt amazing, but greedy anal slut that she was Alex craved more. A few minutes later she technically got it, but it wasn't quite what she was hoping for.

What she got was first Haley burying her face in her cleavage and motor-boating her big tits shamelessly for a few long seconds, and then she latched her mouth to Alex's left nipple and began sucking it like a desperate woman.

This of course made Alex moan extra loudly in pleasure. Well, the motor-boating actually made Alex giggle a little, but she still moaned both from the pleasure of continuing to slide her ass up and down the dildo and in anticipation of what was to come.

After all, when it came to her big boobs Haley was so predictable, and sure enough her big sister started moving back and forth, licking and sucking Alex's nipples as Alex continued doing her best to anally ride Haley's strap-on dick.

Haley was basically indulging in her two favourite things ever, fucking her baby sister in the ass and burying her face in her big titties. If she could have only seen Alex's meaty cheeks jiggle as she bounced up and down on her lap it would have been perfect.

Well, better. What would be truly perfect was if she could get a good look at Alex's jiggly ass and bouncing boobies. True, she was getting an up close look view of the latter, but it wasn't quite the same.

It was awesome in its own right, especially if she paused sucking Alex's nipples for a few seconds so those giant tits could hit her in the face, but once she started it was always hard to stop sucking her kid sister's yummy little nipples. Especially when she was making Alex whimper so wonderfully.

"Haley please, I need to cum!" Alex whined.

"No, from the sounds of it you want to cum." Haley pointed out a few seconds later when she reluctantly removed her mouth from Alex's nipples, "When you truly need to cum... maybe I'll let you."

With that Haley again latched onto the nipple she had been sucking on and bit down harder than Alex liked, almost breaking the skin and causing her poor sibling to cry out pitifully softly. Which did the trick, Alex whimpering pathetically but offering up no more complaining, at least for the time being.

Haley rewarded her by spending extra long-running her tongue over that nipple, soothing it from the punishment she had given it before finally going back to giving both nipples the attention they deserved.

She also occasionally moved her hands from when they had been shamelessly caressing Alex's meaty cheeks to her little sister's big boobs so she was pushing one into her mouth more firmly while continuing to give the other attention.

Of course this would just mean that Alex would become more needy, but Haley was determined to enjoy this while it lasted. After all, she could never get enough of these big boobs, and she always loved worshipping them when Alex wanted her to do something else, or in this case when they were in the middle of something else. As a little consolation prize Haley occasionally thrust upwards into that big butt.

Not nearly as hard as she could, but enough to make Alex let out an extra loud cry of pleasure. Mostly though she became lost in the feeling of Alex jiggling around her, and the taste of her needy, and the sound of her increasing desire to cum, which ultimately Alex verbalise.

"For the love of God Haley, make me cum!" Alex snapped a few times, before begging as humbly as she could, "Please Haley, make me cum! I seriously need to cum. Oooooooh, I love having your big dick up my fat ass, mmmmmm yeahhhhhhh, I fucking love having my big sister's strap-on dick up my ass, ohhhhhhhh, and I love riding it. Mmmmmm, I love riding your big dick Haley, ooooooh, and bouncing my big boobies in your face, but I need to cum. Ohhhhhhhh fuck, please sis, please fuck my ass and make me cum. Or let me do it. Just please, make me cum. Please! Make me cum, make me cum, make me cum, OH YES! That's it, fuck me, ooooooooohhhhhhhhh fuckkkkkkkkkkkk!"

As much as Alex begging her to make her cum was Haley's favourite sound ever and something she could listen to forever she decided she'd show her little sister mercy, at least temporarily, and made her move.

Namely to lower Alex down onto her back, reluctantly pull her face away from her sibling's big boobs, slide Alex's legs onto her shoulders and then began to gently butt fuck her baby sister once again.

She then began slowly building up the pace, allowing for Alex to think this was finally it, that Haley was about to make her cum. Unfortunately for Alex she was in for a nasty surprise, as for her first time ass fucking her kid sister in weeks Haley has something little more epic in mind.

Alex was blissfully unaware of that and gave up her begging for more in favour of looking up lovingly at her sister/the woman she loved before closing her eyes and allowing the sensation of getting her ass hole drilled by a big dildo to wash over her.

God, could there be anything better than this? Her own sister thrusting a strap-on in and out of her most private hole, the hole she pooped from, Haley turning it into her personal fuck hole, or more accurately reminding Alex that's exactly what it was, stimulating places inside her she hadn't known existed before she started this incestuous affair, making her feel so very good. And like what she was, an anal slut.

Yes, Alex thought, she was a shameless ass whore, getting off on what most decent people wouldn't even consider doing, becoming so addicted to anal sex she couldn't go a full month without begging her own sister to sodomise her again.

And she had only gone so long as she did because it had been so thrilling to finally turn the tables and fuck Haley's tight little ass, but now Alex didn't think she could ever go that long without knowing the heaven of getting her butt pounded by her big sister, and she definitely intended to hold Haley to her word and give her the constant ass fuckings that a total anal slut like her needed on a daily basis. Yes, she needed to be fucked in the ass just like this. Or more accurately a little harder.

For a while Alex was completely lost in her pleasure, but she became increasingly aware of the fact that Haley, being the goddess of butt fucking that she was, had effortlessly sodomised her to the edge of orgasm, but was now keeping her there with no sign of pushing her over the edge.

Opening her eyes Alex whimpered, or more accurately whimpered even louder than before, when she saw the look on her evil sister's face, because it couldn't be more clear that this was Haley's plan. Haley was torturing her this way was revenge for turning the tables on her, and for a while that was wonderful but now Alex seriously needed to cum.

Making that known Alex whimpered, "Haley, please make me cum. I seriously need to cum. I, ooooooooh aaaaaahhhhhh, I didn't mean it before, but I do now. Ohhhhhhhh, fuck! Please sis, make me cum! Mmmmmm, I need my big sister to make me cum. Please? Pound me, ohhhhhhh, pound my ass sis! Pound my big fat slutty ass! Ooooooooh, I need my big sister to butt fuck me, aaaaaahhhhhh fuck, I need my big sister to fuck me in the ass, mmmmmmm, I need my big sister to fucking sodomise me, ah fuck, sodomise me! Misuse my fucking butt hole! No, don't just misuse it, wreck it! Ooooooohhhhhhhh, fucking wreck my rectum Haley! Fucking wreck it! Yesssssssss, slam my little shit hole and show me who's boss. Mmmmmmm, remind me what that hole is for! Yeahhhhhhh, remind me that it's yours! Remind me that it's your fuck hole, yours to use whenever and however you want. Remind me that my ass hole is made for fucking and nothing else. Fucking remind me by slamming that bitch hole and making me cum!"

"Nice job at manipulating me, loser!" Haley smiled, pulling her cock out of Alex's ass and lay down on her back again, "But if you wanna cum, first you're going to need to ride me again, and this time I want you to present your hole to me. Come on, sit on my cock and spread those cheeks. Show me that sweet little bitch hole swallowing my dick."

Gritting her teeth to stop herself from offering up some kind of insults Alex did as she was told, reaching back to pull apart her ass cheeks as wide as possible before lowering herself down on her sister's Dick, giving Haley a perfect view of the penetration.

It was probably for the best, Alex was unsure in her current state she could offer up anything remotely witty, and Haley might punish her for it with another hour of gentle sodomy or something.

Besides, Alex forgot all about her anger as that wonderfully big dildo slid back easily into her loosened back hole, and then all the way through her back passage. Honestly Alex could have just sat down on it without the need to go slowly, but again she feared retaliation from Haley so she did as she was told.

Going slowly was actually kind of enjoyable, Alex very much enjoying this feeling of that cock re-entering her horny little ass hole, the younger of the two brunettes becoming more and more excited with every inch which entered her bowels and then she practically let out a squeal of glee when she was once again sitting on Haley's lap.

Although that might have been from beginning to bounce up and down on that dick, which she did immediately, although again she didn't remove her hands from her cheeks without permission.

No, she was just way too desperate to cum, so she obeyed everyone of Haley's instructions, including a few minutes of gentle bouncing. Which admittedly felt good, but not good enough, which was why she soon begged for permission to cum again.

"Haley, I'm so sorry I tried manipulating you, but please, please make me cum!" Alex whimpered pathetically, "I seriously need to cum so fucking bad! It hurts. It seriously hurts. Pleassssseeeeee, I'll do anything, just make me fucking cum! I'll be your bitch forever! I won't try and top you ever again, I swear. I'll just be your butt slut. Oooooooh yessssssss, I'll just be your pussy licker, your ass whore, your lesbian sex slave, just make me cum! I'll, I'll pull down my pants and show any guy who hits on me my gaping ass hole to prove that I'm my sister's personal anal slut, just make me cum! I'll... I'll, aaaaaaaahhhhhhhhh fuckkkkkkkk, I'll drop out of college and devote my entire life to being your butt sex loving dyke bitch, just make me cum!"

"I don't think you mean that." Haley teased.

"I DO!" Alex screamed at the top of her lungs, "I SWEAR I'LL DROP OUT OF COLLEGE AND BECOME YOUR FULL TIME BITCH IF YOU JUST MAKE ME CUM! AAAAAAAHHHHHHHHHH GOOOOOODDDDDD, FUCK MY EDUCATION, I NEED TO CUM!"

"Wow, I believe you." Haley said in disbelief, stopping entirely, "But you'd never forgive me if I made you drop out, and I totally want you to top me again. But when I do it's only because I let you. I'm the real top of this relationship. You understand that now, right?"

"YES, YOU'RE THE TOP! YOU'RE THE TOP AND I'M THE BOTTOM!" Alex screamed desperately, "YOU'RE THE TOP AND I'M YOUR LITTLE BITCH WHO TAKES IT UP THE BOTTOM! NOW FUCK ME!"

"Erm, no." Haley said, and then before Alex protest said firmly, "You do it! Bounce that big fat ass back at me and make yourself cum. Mmmmmmm yessssssss, that's it sis, show me you understand your place. Show me you understand you're the bitch in this relationship. Show me you understand you're nothing but my bitch!"

The second she had permission Alex let go of her cheeks and started hammering her fat ass up and down that big cock. There was almost no gentle build up, Alex trying to ruin her own rectum right from the get go. Literally.

At least temporarily, because Alex wanted her ass to gape as wide as the Grand Canyon for at least the rest of the day, and ideally the rest of the week. Partly to remind her that she was a shameless anal whore, but also because she wanted for Alex to be able to fuck her bitch hole at a moments notice.

No lube or preparation needed, just Haley sliding her strap-on back inside Alex's shit pipe and anally abusing her again. Or better yet she could handcuff Haley onto the bed and torture her for a few hours by masturbating her slutty little ass hole in front of her. That could be fun.

Mostly though Alex wanted, no, she needed to cum, and thankfully thanks to all that build-up it wasn't that long before her eyes went wide, her head tilted back and she let out a loud scream of pleasure as the kind of ecstasy which she could only feel from a hard butt pounding flooded her body.

It was so amazing she actually stopped sodomising herself on her sister's big dick for a few long seconds, which just showed how horribly out of practice Alex was at what was clearly her purpose in life.

Although at least she made sure she was completely sitting on Haley's lap so every inch of that strap-on was buried up her tailpipe. Still, it wasn't long before she renewed her efforts and began violating her ass perhaps harder than ever before.

Soon Alex became like a wild animal relentlessly pleasuring itself on its lover's dick, and just when she didn't think it could get any better Haley began thrusting upwards into her fat ass, making Alex's cum squirt even faster and harder out of her cunt, and maybe even make her scream louder and more ear piercing.

Just like that all was forgiven, Alex forgetting all about the pleasurable torture that Haley had put her through and cursing her older sister's name in favour of falling even deeper in love with her.

She might feel differently later, or at least much later, but right now Alex was blissfully happy, and a few minutes later Haley did something which made Alex's brilliant mind to almost literally melt away and truly leave her a mindless animal.

Haley could never get enough of Alex's big butt jiggling in front of her, and in their current positions, and Alex's current mood, that fat ass was perhaps jiggling more violently than ever before.

Honestly Haley could have probably closed her eyes and enjoyed it just as much as the feeling of those cheeks jiggling against her thighs was incredible, but she didn't want to miss a thing. Not when that big booty was bouncing up and down so rapidly in front of her, and not when her baby sister was cumming this hard for her.

Yes, that was partly because of how Haley had punished her for turning the tables, but she had also done that to remind Alex just how hard she could make her cum, and that was definitely paying off right now.

Of course even after over a year of fucking each other Alex's stamina had it's limits, and it always would, so the second Alex started slowing down Haley decided to really remind her kid sister just how hard she could make her cum, and who the true top was in this relationship.

Which she did by sitting up, roughly pushing Alex down onto all fours and pressing herself up behind her, all without allowing more than a couple of inches of cock to escape her little sister's ass hole.

Then once they were in the position they started in Haley took a firm grip of Alex's hips and began to butt fuck her baby sister again, quickly working from a slow and steady rhythm to get her groove back up to a deep, hard anal pounding which had Alex squealing and cumming for her again.

When she really got going Haley screamed at the top of her lungs, "THAT'S IT, CUM FOR ME YOU LITTLE BITCH! CUM WITH MY COCK UP YOUR FAT ASS! OHHHHHH FUCK, TAKE IT! TAKE IT IN YOUR BITCH ASS! YEAHHHHHHHH, NOW YOU UNDERSTAND, DON'T YOU ALEX? YOU UNDERSTAND I'M THE TOP AROUND HERE! MMMMMMM AND YOU'RE THE BOTTOM! YEAHHHHHHH, YOU UNDERSTAND YOU'RE THE FUCKING BITCH AROUND HERE AND I OWN YOUR FUCKING SHIT HOLE! YEAHHHHHH, MY BABY SISTER'S BUTT HOLE IS MY FUCK HOLE AND IT ALWAYS WILL BE! OOOOOOOHHHHHHHH FUCKKKKKKKKK, YOUR FAT ASS IS MY PROPERTY SIS! MINE! ALL FUCKING MINE! I OWN YOU! YOU'RE MY BITCH! AAAAAAHHHHHH GOOOOOOODDDDDDD, OH FUCK ALEX, YOU'RE MY BITCH YOU'RE MY BITCH YOU'RE MY BITCH YOU'RE MY BITCH YOU'RE MY BITCH AAAAAAHHHHHHH YEAHHHHHHHHHH, AAAAAAAAAAAHHHHHHHH FUCKKKKKKKKKKK!"

The only reply she got from Alex was more squeals and screams of pleasure, and her kid sister backing that big booty up against her, the two Dunphy sisters working together to make sure that Alex's fat butt got pounded as hard and deep as possible.

Just as importantly the two siblings made sure that there was no way Alex's big round cheeks could jiggle any more than they were right now, Haley's eyes so locked on that bouncing booty that it took her a long time to notice when Alex finally stopped, exhaustion catching up with the poor younger sister, causing her to collapsed face down in the bed sheets become nothing but a big jiggly ass for Haley to use for her pleasure. Which to be fair, was what the sisters agreed was Alex's true purpose in life.

When Haley did finally realise she almost stopped immediately, but then she heard a groan from Alex, proving that her kid sister wasn't unconscious, at least not yet. As she was so very close to another orgasm Haley so she decided to continue.

Not that she had ever stopped. No, her greedy body had continued brutally pounding her sister's butt hole with her dick, in the process bashing her clit against the stimulator on the inside of the harness which had already made her cum so much throughout this butt wrecking session alone.
