Meanwhile, Kitty and Lizzie’s experiment was working incredibly well. Ava had easily convinced Jill to break up with her boyfriend and the mind control waves radiating off of her were effecting everyone in the family.
Jill and Ava had gone shopping yesterday. That would’ve been fine, but Ava was insistent on dressing Jill up. Even besides that, Jill had sworn she caught Ava peeking in at her. The worst part about it was that she kinda liked it...
Jill hadn’t believed in makeup at all before, but now she looked almost like Ava. She’d also started stuffing her bra, wearing shorter skirts, and wearing heels, all uncharacteristic of the tomboy. Even more surprising was the bright sparkly pink color of the dress she was wearing today; she’d always hated pink, but she no longer knew why! It was such a pretty color, wasn’t it?
Even more confusing was that her sister hadn’t even picked it, like she had with the rest of her new clothes. Ava picked it up all by herself. This wasn’t like her, was it? And if it wasn’t, why wasn’t she? Girly girl bimbos always seemed so much happier anyway...
And even though she’d been straight before, she now no longer felt any attraction towards men... in fact, she felt a strong disgust towards them. She was now a lesbian with a bimbo fetish.
The problem was, she hadn’t been attracted to Ava before since that was her sister.
However, the mind control was so strong that she’d started feeling it in the past day or so.
So when Ava started masturbating for the tenth or so time that day, Jill found herself spying on her sister.
“Just a peek won’t hurt... right?” Jill said.
Ava left her door open anyway, what was the problem? The loud moans could be heard down the hall. It was almost like Ava was doing it on purpose.
And Jill couldn’t help herself. She started fingering herself as she watched Ava fuck herself with a big pink dildo.
What Jill, and for that matter anyone, didn’t know, was that masturbating in Ava’s vicinity greatly increased the mind control. On top of that, any woman that finds someone masturbating will also have the urge to masturbate or even have sex with the person masturbating in Ava’s vicinity, making the mind control even stronger. The more people masturbating or performing anything sexual, the stronger the mind control.
Of course, Jill didn’t know this. Neither did Jill and Eva’s mom, Danielle.
So when Danielle walked over to hear and see her daughter spying on her sister and masturbating, she found herself unable to stop Jill.
Anger was replaced with... understanding. She walked up quietly to Jill.
In one fowl swoop, she put one hand against Jill’s mouth, the other on her tiny breast, pinching the nipple.
“Mmphpph, mom?” Jill whispered out.
“Yes sweetie. Don’t worry, just be quiet and keep touching yourself. Mom’s here to help.” Danielle said, nibbling her daughters ear.
The words felt dirty as they left her mouth, but both girls didn’t care. The thoughts were normalizing themselves inside their brains.
The urge to be a bimbo was increasing at the highest rate ever. The 30 minutes that they stood there was stronger than the two weeks since Ava had been “fixed.”
Another unknown side effect was that once Ava came, all three would cum, providing one last burst of the super strong mind control.
And when Ava came, so did Danielle and Jill.
Ava suddenly fell backwards, a look of pure pleasure on her face as she recovered from her orgasm.
Danielle pulled Jill into a tight kiss.
“That was great sweetie. Let’s do this again.” Danielle whispered into her daughters ear.
Jill could only nod. She slipped away soon after her mother did, the urge to be a bimbo much, much stronger than before, incest now normalized in her changing mind.
