Joel's been wondering how in the world his little step-sister's tits have grown from a mere "A" cup up to the kind of big boobs you'd see on a porn star- a massive "DDD" cup, on a school girl!!! Tonight, while their parents are out, he'll find out... to his demise. You see, he's already asked Katelyn about an odd looking "devise?" that he spotted in her bedroom. As always, she came up with something random to say about in less than one beat of a heart.

Even though he believed her, he's still been curious. Without even asking about it again, Katelyn took the pleasure of using it on ...

Joel's been wondering how in the world his little step-sister's tits have grown from a mere "A" cup up to the kind of big boobs you'd see on a porn star- a massive "DDD" cup, on a school girl!!! Tonight, while their parents are out, he'll find out... to his demise. You see, he's already asked Katelyn about an odd looking "devise?" that he spotted in her bedroom. As always, she came up with something random to say about in less than one beat of a heart.

Even though he believed her, he's still been curious. Without even asking about it again, Katelyn took the pleasure of using it on him as soon as their parent's left.

(Start of video) It's a SHRINKING DEVISE! After revealing what the hidden mystery devise actually does, she next reveals the secret her huge tits. Come on now... it's only natural to check out your siblings. He hasn't been able to ask her because that'd be awkward. However... things are about to get a lot more awkward, and Katelyn's going to him to have a good time!

She's been shrinking he classmates and doing something very naughty with them. School girls are so horny. So curious. So wanting to experiment! And... her shrunken classmates wanted exactly what she started off doing to them, until she took complete control by shrinking them and using them to make her tits grow with each shrunken school crush.

How? By... swallowing them with her pussy! The thought had crossed her mind, that, since her step-brother has her exact DNA that it'll make her boobs grow so MASSIVE that she'll be able to seduce anyone she ever wants. (Even their parents. Who knows how big that would make her tits. Woooah!) She's absolutely addicted to making her tits grow more and more that it doesn't make her care about her family, starting with her step-brother as the first experiment.

--This video features an editing style that seamlessly switches back and forth from third person view to the shrunken brothers point of view looking out inside of the bowl he's in. And it doesn't end there. You'll also get to see his view INSIDE of his massive (in comparison) sisters pussy while the view switches from third person view to internal pussy view with realistic internal muffles, and some faint squishes, included.
