Claire Dunphy felt confident that she had won her latest battle with her oldest daughter Haley. The two of them had been fighting pretty much ever since she gave birth to her, especially when Haley entered her teens. But of all the battles of will, this one was the one that really mattered. It was certainly the one Claire most wanted to win, as it seemed Haley was truly hers now.
Which of course meant both her daughters were hers, as ever since they had secretly got together Alex and Haley had been a package deal. And oh, what a perfect package it was, with one daughter being toned and tight, and the other being voluptuous and juicy, making them the perfect lesbian sex slaves for the perverted mother.
After installing video cameras in the love nest of her daughters Claire was able to watch proof of that every time she came to visit them. Because as much as she loved fucking her daughters Claire truly loved her husband, and could never see herself leaving him. Also while she had wanted both her baby girls to be submissive to her, she hadn't wanted to stop their romantic relationship.
In fact, it warmed her heart to watch the video tape back of not just her daughters having sex with each other, but to see all the little moments of love and tenderness they shared. The kissing, the soft words, and even the way they touched each other when they weren't having sex, was so beautiful and erotic that Claire just couldn't get enough of it.
Which was why she spent hours watching them together in their entirety, only fast forwarding the truly mundane bits, or obviously when they weren't together, when she first got in instead of skipping straight to the sex. If they were lucky, Haley and Alex would be allowed to fuck while they did this, which mostly meant one of them preparing the other's butt hole to be used by Claire as the fuck hole it was always meant to be.
And/or if the footage ever became too much for her Claire would give one of them the privilege of eating her pussy, maybe with the other tonguing her ass at the same time. But mostly Claire kept them like this, kneeling either side of her, both completely naked except for the collars around their necks, and the butt-plugs up their asses while checking to see if they had been good.
She was always expecting to see Haley finally break free of her control, and/or lost herself to her overwhelming lust for Alex's big fat ass, and brutally sodomise her baby sister right in front of the cameras, not caring if her Dom Mom saw it. Or perhaps a tell-tale sign that the footage had been altered, the sneaky Dunphy sisters trying to hide the truth from their mother.
However six months after completely breaking Haley, both of the sisters were continuing to be good, and that meant it was finally time to do something which was a long time coming, and would be the perfect way to celebrate this happy occasion. Hell, Claire was so excited she almost fast forwarded through some of the good stuff, but she just managed to restrain herself in the name of teasing her daughters.
When she was finally finished checking the footage Claire slowly turned off the computer, pushed herself back so she was looking at both her girls then grinned wickedly and widely at them, "Good girls. Mmmmmmmm yessssssssss, that's what I like to see, my bitches behaving themselves in saving their asses for Mommy just like all good daughters should."
"Yes, mmmmmmmm, all daughters should." Alex agreed, buttering up her mother before asking hopefully, "Does that mean that you're going to double butt fuck me Mommy?"
Claire pretended to look thoughtful for a moment, and then smirked, "Maybe."
"Moooooooommmmmmmmm!" Alex snapped, whining like Haley used to when she wasn't getting her way, "You promised!"
"Alex!" Claire snapped back, "I trained you better than that."
"I know, and I'm so sorry Mommy." Alex whimpered, "I just want it so bad."
"Well 'I want', doesn't always get." Claire grumbled as if Alex was still a child, and then when her youngest whimpered pathetically she slowly turned to her eldest, "How about you Haley? Huh? Do you wanna butt fuck your little sister? Huh? You finally want to see those big meaty cheeks of hers jiggle for you again? To gape your total bottom of a girlfriend? To ruin her perfect little fuck hole? Huh? Answer me!"
Haley thought long and hard about her answer, and then while keeping her head lowered in submission softly told her top, "Yes. Oh God yes, Alex's fat ass is heaven and I've missed fucking it so much. You know I have Mommy. Anything else would be a total lie. But only if it pleases my top. That's the most important thing to me. Ohhhhhhhhh yeahhhhhhhhhh, I wanna please my Dom Mom over anything else, even butt fucking my baby sister, which not so long ago I thought was impossible, but now? Mmmmmmm, now I'm hoping that my Mommy will let me find out what it's like to fuck Alex's ass as a bottom. Which will make Alex the biggest bottom by far."
There was a brief pause, then Claire smirked, "Yes, I like this answer."
As their mother looked at them thoughtfully Haley cautiously added, "I'm happy you liked it."
"Oh shut up and eat ass." Claire ordered, smiling wickedly as she elaborated, "Mmmmmmm yessssssssss, get on the bed Alex, in your natural position, bent over and ready for your ass to be violated. And Haley, mmmmmmmm, you lick her ass hole. Oh yes, tongue your sister's butt hole and get it nice and ready for me to fuck. Oooooooooh fuck yeah, mmmmmmm fuck!"
"Yes Mommy." Haley eagerly replied and obeyed.
