"Please Mommy, I'm so sore." Haley whimpered.

"You should have thought of that, before you butt fucked your sister without my permission." Claire growled in her ear, "Now shut up and gimme that ass!"

Haley Dunphy cried out with a mixture of pleasure and pain as her ass hole was penetrated for the fifth time that night by her own mother. On the bright side her butt hole was gaping wide open, her back passage almost as cavernous, so the big dildo slid into her battered behind like a hot knife through butter.

Oh yes, it only took seconds for her Mom's thighs to crash against her butt cheeks, announcing every single inch of that huge strap-on was buried deep within her bowels. Then the older woman gave her a few long seconds to adjust to this latest anal violation before she started pumping her hips back and forth, causing the cock to slide in and out of her ass and officially begin the latest round of the sodomy.

This time Haley found herself in an unusual position, namely standing with her front pressed into the see-through glass of her shower, her Mom stood behind her and pressing her tits along with her hard little nipples into Haley's back while the other woman reached round to cup her tits.

Her mother was also nibbling on her neck, her tongue and teeth grazing already thoroughly marked flesh, making it crystal clear she wasn't just reminding Haley that her girlfriend/sister was now the property of the woman who gave them life, but she was too. Which normally kinky little Haley Dunphy would gleefully welcome, but her Mom had been threatening to turn her into a pure bottom, and she had never been so close to achieving that goal.

It wasn't like Haley didn't fantasise about such a thing even before she started having regular sex with her mother, but the thing which always made her stop wanting that fantasy to become a reality was her dear sweet Alex. Her baby sister. The love of her life. The best girlfriend a girl like her could ask for. The most beautiful girl in the whole world, with a pair of gigantic titties and a big fat ass which was made for fucking.

Haley truly believed that she would keep most of those things if she broke, but the thought of never again pounding her little sister's giant booty was easily the worst nightmare she'd ever had, and previously it had kept her from breaking completely, but even that may fail her now.

Normally Alex was here too, meaning their mother's attention was divided between them, and first there would be pussy eating, butt munching and tit worshipping, particularly that last thing taking up a lot of time when Alex was involved. Maybe a spanking first, but the other stuff was a nice buffer between that and the anal pounding, especially because Haley's tight little ass was normally their Mom's desert after she and Haley had taken it in turns destroying Alex's big booty.

And/or maybe there would be some DP fun, Haley staring lovingly into her baby sister's eyes as she was taken in both holes, and get constantly reminded why she had to stay strong, often after her little sister had received the same treatment. But tonight it had been non-stop anal sex for her, and it was just too much.

Which Haley tried to point out with a whine, just before the latest round of sodomy began, "Moooooommmmmmmm, please! It's too much. My butt is about to burst. Can't I eat your pussy instead?"

Claire raised an eyebrow, "Did you give Alex the same option?"

Haley blushed, "I..."

"What did you say?" Claire pushed, "What did you say when your own sister begged for mercy when you were abusing her poor little butt hole?"

There was a brief pause and then Haley admitted, "That, that she should shut up, and her ass was made for fucking."

"Yeah, that's right. That's what you said that to your own sister... your own baby sister... and you were right! Alex is an anal whore, who's purpose in life is taking it up her fat ass." Claire growled in her ear, "But as we've established already tonight, you're just as big an anal whore as your sister, with a tight little ass which was equally made to be fucked. Mmmmm, fucked by a family member. That's what your ass is, and that's what it's going to get. So take your own advice, bitch... shut up, and take it up your ass that was made for fucking!"

Claire began sodomising her daughter with absolutely no sympathy for her. In fact Claire really got off on the fact that Haley was whimpering, gasping and crying out with pain and discomfort as well as joy and pleasure during their latest round of incestuous butt sex. It was one Haley deserved after being so naughty, and not just for using Claire's property without permission.

Oh yes, Haley had always been a naughty girl, whining and crying when she didn't get her way, breaking the rules, and doing whatever she wanted. Doing whoever she wanted. Hell, she had not only dragged Alex into sinful debauchery, but her own mother as well, meaning everything she was taking now she had brought upon herself.

Admittedly this wasn't entirely about punishment, as Claire desperately wanted to break Haley completely and thus turn both of her daughters into her bitches. Well, they already were her bitches, but she wanted them to be total bottoms who would only eat each other out when alone together, and leave Claire to give them the relentless ass poundings they needed.

It had become her greatest fantasy, something she wanted more than anything, ever, and now Claire was so close to it she could taste it. She just needed to make Haley cum a few more times with a dick in her ass to achieve her ultimate goal, and then they would finally be the kind of modern family she wanted them to be.

Luckily her daughters really were the biggest butt sluts in the entire world, and maybe the universe, because it was just so easy to make them cum when their most private holes were being violated. Right now the only thing holding them back was Claire herself, who chose to take a few long seconds to enjoy this unusual position.

Her favourite position for her little girls was easily when they were face down or on all fours, their perfect asses perfectly on display for her, but Claire made sure to screw them in a variety of different positions to keep things fun, and this position was a lot of fun. Oh yes, Claire loved being able to press their bodies totally against each other like this, their lower halves only partly separating with every thrust while Claire continued working her magic on Haley's neck and tits.

It also helped that those initial thrusts were slow and gentle, allowing Haley's battered butt to slowly relax and remember what it's true purpose was, meaning those initial cries, gasps and whimpers of pain and discomfort eventually dissolved into pure pleasure.

That pain and discomfort likely made a brief comeback when Claire picked up the pace, but her anal whore of a daughter of course only loved that even more, which was clear from the sounds she made, the way her body reacted, and eventually the things she said. Oh God, nobody talked dirty quite like Haley Dunphy, her words almost making Claire cum on the spot. Somehow she resisted that urge, just so she could give this little bitch what she deserved.

"Fuck me Mommy! Fuck me harder!" Haley cried out joyfully in her best little girl's voice, "Pound my slutty little ass hole and make me cum! Yessssssss, ooooooh fuck, make me cum like a bitch with a dick in my butt! Your big dick Mommy, mmmmm, I love your big dick in my ass! Please Mommy, bang me in the butt hole. Ohhhhhhhh yessssssss, bang it hard and deep, mmmmm, and make it yours! All yours! If you can. Ohhhhhhh yeahhhhhhh, that's it Mommy! Pound me, pound your baby girl's back hole and make it gape for you! Take it, mmmmm, break it, ohhhhhh, make it yours! Make me all yours Mommy, break me by breaking my butt hole! Destroy it Mommy, destroy your own daughter's shit hole you perverted bitch! Please Mom, fuck me and oooooooohhhhhhhhh yeeeeeeeesssssssss, ooooooooohhhhhhhh Goooooooodddddddd, oh, oh, oh, oooooooooohhhhhhhhh Moooooommmmmmmyyyyyyyyy!"

Haley of course didn't want to be completely broken, but teasing her mother with it always made the older woman fuck her harder, and this time was certainly no exception. If anything it worked too well, her Mom starting to pound her slutty little ass sooner than usual, sending Haley to the edge of orgasm in what felt like seconds.

Initially she tried to keep talking, although she had no idea what she was saying, and then Haley became just a complete incoherent wreck as she was dominated by the only person who had succeeded in doing so. Alex bliss her heart had tried, but she hadn't even got close to this, and boys had always been too nice with her. Oh yes, Haley might not want to be a pure bottom, but every so often this was exactly the treatment she needed.

Again the problem was she was beyond exhausted, having being butt fucked into near unconsciousness four other times, and it was hard enough just to stay on her feet which was propped up by the shower with another body pining her to it. Even then Haley thought she was going to collapse at any minute, and then things only got more tricky later when suddenly her mother shuffled back and then pulled her back with her, and then shoved her upper half downwards.

Haley was far too exhausted at that point to stop her face from bashing into the glass, but it wasn't hard enough to break it, and it gave her something to rest her face on, and her hands against the next few minutes. But even that wasn't enough, her face sliding down the glass until she was bent in half, the only reason that her lower half remained upright being the vice like grip her Mom had on it.

Of course at that point she was barely aware of it, and she certainly didn't care, as she was cumming over, and over, and over again. Each climax was easily as powerful as she'd ever had, if not more so, as everything just caught up with her.

The fact that she was taking it up the butt, the fact it was her own mother doing it, and the fact that it was in the apartment she shared with her girlfriend/sister was certainly a powerful combination of its own, but then there was also the fact that this was her own mother trying to turn her into a total bottom. Her total bottom. Oh yes, her Mommy wanted her to be a total bottom, and in moments like this it was hard for Haley to remember why she was resisting.

Then even in her most submissive moments she remembered the pure heaven which was Alex's big fat ass, and if that wasn't true love Haley didn't know what was. Oh yes, she loved that big fat ass so much that the desire to fuck it overwhelmed even her own need for selfish pleasure. Her love for Alex, her own sister, was more important to her than her own pleasure.

In fact Haley's last coherent thought for quite a while was that while her Mom was a total ass wrecking stud even the greatest physical pleasure she'd ever known couldn't compare to the satisfaction of pounding her little sister's big fat ass. Then the ecstasy overwhelmed her, and she became nothing but her own mother's personal little fuck hole.

Claire knew better than anyone, except Haley, just how heavenly pounding Alex's big booty was, which was why she wasn't surprised Haley hadn't broken completely yet, despite being as big a bottom as her sister. Oh yes, both of Claire's daughters were total bottoms, who loved it up the ass, which Haley once again proved by just how hard she came for her Mommy.

Which in turn made it hard for Claire not to cum on the spot, but she held back in the name of giving Haley's heavenly little booty everything she had, and more importantly make her baby girl cum as much as possible. Both because she wanted to break her, and just because she had a reputation to uphold.

Ironically, and sadly, she wasn't expecting Haley to break because of this. After all, Haley had survived multiple butt fuckings before, and Claire wasn't even expecting her to break after a whole night of non-stop ass pounding, which was exactly what Claire was going to give her tonight.

It would be a very, very welcome surprise if she did, but she was fully expecting Haley's love for her sister's big fat ass and just Haley's stubbornness to once again when her the day. But that was okay, because Claire had a plan for breaking Haley once and for all, but first she needed to thoroughly loosen her oldest daughter's back passage, and Haley's disobedience and using Alex's big jiggly butt without permission was the perfect excuse Claire had been waiting for.

She had known it was only a matter of time before Haley would screw up like this, and thankfully she was proven right. Although if she'd had to wait much longer Claire would have probably done this anyway, because as tempting as it was to use every ounce of her strength on one butt fucking it might be even more fun to stretch it out over a period of time and take Haley in multiple positions.

Even when it came to the brutal butt fucking Claire found herself moving Haley into different positions almost without thinking about it, mostly so she could concentrate on her thighs smacking against that little booty, creating the most wonderful feeling, and maybe more importantly sound. Oh yes, the sound of flesh on flesh echoed throughout the room, almost as loud as Haley's screams of ecstasy, as her own mother pounded her like a wild animal.

That, the constant bashing of the other end of the dildo against her clit, and the sheer joy of sodomising one of her daughters of course ultimately caught up with Claire, sending her over the edge of the kind of powerful climaxes she'd only ever received while brutalising the butt holes of one of her baby girls. Then like the proud top she was Claire powered through that climax, and the ones that followed, so she could truly give Haley a rectum wrecking.

And it was very, very tempting to use every ounce of her strength at this point, but again she held back just enough so they were able to continue, even if Haley would have to be on top for it. Just not in the way Haley would have liked. No, Haley may be still insisting that she wasn't a bottom, but tonight she was very much Claire's bitch, something the older woman proved with another simple act.

Namely by pulling her cock out of Haley's ass, smacking it roughly and ordering, "Spread your cheeks for me you little bitch! Mmmmm yeah, show me that pretty little gape!"

"Yes Mommy." Haley whimpered in reply.

Haley mostly whimpered out of disappointment for no longer receiving orgasms, and for that big beautiful cock no longer being up her butt. Of course given how this night was going Haley had little doubt that she would soon be receiving both again, and in the meantime the consolation prizes were kind of fun. Which of course included reaching back and spreading her cheeks apart to show the older woman her handiwork.

Although it certainly couldn't really be called a little gape, not after all the work her Mom had done stretching it out, Haley thought with a wicked grin. Which in turn was almost enough to keep her on her feet, but her legs were like jelly and she just had to slide down onto her knees. Luckily she was able to keep her cheeks spread as she did so, which meant she didn't get in trouble.

In fact Claire seemed to be way too preoccupied with the gape to notice, "Ohhhhhhh yessssssss, such a pretty little gape, mmmmm fuck yeah. Or should that be, pretty little giant gape? Oh yeah, Mommy really stretch that ass, didn't she Haley?"

"Yes Mommy, you really stretched my ass." Haley moaned softly, "Mmmmmm, you stretched my ass sooooooo good!"

"Yes I did, yes I did." Claire mumbled mostly to herself, "Do you like it slut? Huh? Do you like having your ass stretched out and loose from your Mommy's dick?"

"Of course Mommy, what daughter wouldn't?" Haley cheeked, before quickly clarifying, "Mmmmm, but I don't like it as much as pounding my little sister's big fat ass."

"Yeah, I know you don't. Not yet." Claire grumbled, before grinning, "But don't worry, mmmmm, Mommy will fix that. For now, crawl over here and suck your slutty little ass off of my dick, you twisted little whore!"

That was the pot calling the kettle black, but instead of pointing that out Haley simply smiled dreamily and replied, "Yes Mommy."

It had taken Haley a lot to refrain from making that comment, but she hadn't wanted to risk being denied her own heavenly butt cream. So she gave the reply her mother wanted, and then rejuvenated by her love for the taste of her own ass Haley took her hands off her cheeks and then slowly turned around until she was kneeling in front of her mother.

She then smiled suggestively up at the woman who gave her life before wrapping her mouth around the big dildo which had just pummelled the deepest part of her ass. Which was of course followed by a loud and shameless moan as Haley show just how much of a proud ass to mouth whore she really was.

She then continued proving that as she bobbed her head up and down the head of that dick, taking more and more into her mouth with every bob of her head. Although she did stop briefly when the head of the toy was pressed against the entrance to her throat, but that was more to tease her mother than anything else, and it wasn't long before she went even lower.

And then lower, then lower, and then lower until her lips reached the base, announcing that every single inch of that strap-on was stuffing her throat. Which meant that soon there was no more ass cream to clean, but like the eager little cock sucker she was Haley continued bobbing her head on that dick, albeit after a few long seconds to make sure she had every drop of anal juice.

"Okay, that's clean enough." Claire growled, tightening the loose grip she had on Haley's hair so she could pull her off the dick, and then along behind her, "I want you to ride my dick again."

"AH! Yes Mommy!" Haley cried out with disappointment.

Honestly it had been disappointing that her Mommy Top had provided no verbal humiliation during the latest round of ATM, but the gentle strokes to her hair had made up for it. What was far more disappointing was they weren't having a cuddling break, or better yet a kissing and cuddling break.

Because again, Haley's ass was so sore, and she was exhausted, but her Mom had made it clear she had no sympathy for her, and to be fair she had shown no mercy to Alex when it had been her little sister begging for mercy. So once again Haley took her own medicine, allowing the older woman to drag her across the room, and then after her mother put the seat down to the toilet and sat on it Haley awkwardly got into position.

Claire licked her lips as without having to be asked Haley reached behind her and spread her cheeks, giving the Mom the best possible view of the anal penetration and her cock slowly sliding deep into her daughter's ass once again. True, this made it easier on Haley, but Claire like to believe that her baby girl was at least partly doing this for her benefit.

Either way she got to enjoy that beautiful view as Haley slowly but easily sat down in her lap, burying every inch of that dildo deep into her slutty little ass, the little anal whore moaning with shameless pleasure the entire time. Well, there was a little undertone of pain, and even an unpleasant cry every so often, which made Claire feel a little guilty, but she was confident in no time at all that would vanish.

Sure enough Haley was soon crying out in pure pleasure, and bouncing her butt up and down way too fast for Claire's liking. To be fair she started out slow, and even paused for a few long seconds when she was sitting on Claire's lap with the full length of the dick in her butt so they could both savour this precious moment.
