Payback for the Prankster (1 of 2) (Patreon)

Petra is a plump, voluptuous, bosomy BBW math tutor hired to tutor twerpy teen Donnie on his science homework. But Donnie is a real brat with no interest in learning... he'd rather pull pranks! Petra's finally had enough of his bullshit and she decides to fight back. Little does Donnie know that Petra has a secret weapon... her breast milk can make men shrink. And she's going to put it to use! (WARNING: Part 2 of this story does involve crushing, so be warned!)
