"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.
