Grunting dumbly, Princess Sow Cunt sucked Mario's cock all the way in, deep throating the hot stud for all she was worth, while the teens in the doorway videod the whole scene. The grunting reverberated through Mario's hard member, sending him over the edge. His balls contracted, and he started shooting his jizz right down his pigboi's throat. Adam glugged it down greedily, her body slowly swelling even more as she drank her master's cum. She gazed up into Mario's eyes, and he looked down on her, while she bloated bigger and bigger. A new set of breasts appeared below her firt pair, then another and another, her hands and feet darkening and bonding into cloven hooves.
It didn't go unnoticed by Mario that the more time passed and Adam's body naturally changed on its own, the less and less dramatic his magical transformation into a sowboi became each time. Adam was truly growing into the part, for real. Mario didn't know how far Adam's body would transform on its own without magic, but he was looking forward to finding out. He knew it wasn't without natural precident, some animals could even change gender. That thought excited Mario, and a second surge of spooge pumped from his cock down the obese sowboi's throat. The idea of keeping Adam barefoot and pregnant, maybe watching her nurse a litter of piglets, just kept Mario cumming, and his sowboi growing fatter and fatter as the now magical transformation into a 1300 pound obese sowboi came to completion, leaving Adam a dumb, fat, mindless animal.
When Mario had finally cummed all he could, he slowly took his cock out of Adam's snout, letting her lick it clean for him. The boys in the door pocketed their cell phones and disappeared outside, not wanting to hang around now that the muscular one was pulling his swimsuit back on. Mario petted Adam on her hairless head, she grunted contentedly, gazing up at him from the pile of fat she was. "Good girl, Princess. You're the world's best cocksucker."
Mario used a spell so that Princess Sow Cunt could stand, and she did, grunting and still gazing up at her beloved master. The bathing suit Adam wore when they left his parents' place had only been an illusion; Adam had actually left his parents quite naked; not that anyone could see his tiny cocklet and baby balls encased his their forever-prison of fat. But Mario preferred his sows not only barefoot and pregnant, but naked and pregnant. With a small magical flourish, Mario's cum impregnated Princess. Somehow she knew, and she squealed in delight, grunting dumbly, tiny cocklet deep between her legs drooling afresh.
"You're going to have piglets princess," Mario grinned, petting his dim-witted sow on the head affectionately.
The sow would have thanked Mario, had she understood what he said to her. But the truth was, Princess Porkalot was the world's fattest, dumbest, most prize winning sow...and burnt out light-bulbs were brighter than she currently was. "Wree wreee." Drool.
