"... I'm going to modify you, so you won't have any other occasion to cheat on dad, even if paying."
Mom looked at me horrified: "Please, stop... I'm a slut, I did a mistake, but I learned my lesson... I'll be good... please..."
But I was adamantine.
"First I wish your tits and butt to grow."
They started to grow and I let them growing till the weight of them was the most of her body. They were almost as big as the ones you can see on net bbw models. But attached to mom 2'7'' body they were absolutely out of place.
"And now I wish your body would be like hot wax in my hands."
I grab my mom and started to remodel her, while she was screaming and moving.
"Better if you stay still, or you're going to resemble Picasso's Guernica."
In terror mom stood as still as she could, even if it was clear that my remodelling was very painful for her.
I was stretching her tits, when mom passed out in pain. I thought to bring her back in her mind to fully feel the pain, but then I thought it would be nice to see how she would have reacted seeing my handywork just when it had been completed.
So I continued to work my mom's limp body in my hands. I must admit I was growing hard as a rock. But I decided to fight my urges: with my new powers I had to learn to control myself, someway.
When I had done, my tiny mom resembled no more a human being.
I wished for a mirror and then wished for her to fully wake up.
"Look at you now, mom. I bet now you can't get a good fuck from anyone, no matter how much you could pay."
Mom looked in the mirror and let out a scream. And then she screamed again and again. She checked her body to verify it wasn't an illusion. And then screamed again.
I modified her oversized tits, elongating them to her knees. She looked like she had two basketball hanging from her chest.
Then I bent her enormous butt toward the sides. But I didn't stopped there. I enlarged her hips and vagina and anus, till my two fists could get in together. And being her already half her size, that means they were, in proportion, very, very large and gaping.
The same I did with her mouth. And I had erased her nose, so she had to breath exclusively by her mouth.
Then I bent her legs so that when their heels where together their were anyway far apart, letting her vagina and asshole well opened.
To complete my work, I tightened her waist making difficult for her to breath.
"Goff, (BREATH) fwhaf fyou (BREATH) ffif fo me (BREATH)?" she tried to ask, but couldn't get it out clearly, cause her deformed mouth and her reduced lung capacity. She was trying to ask: "God, what you did to me?"
"Shut up! This is your new shape. Better you get used to it!"
Mom was crying, panting and praying, but I couldn't understand what she was saying. Not that I did care, anyway.
I was going to teleport us in my room, when I realized I was taken away by the moment and I had still to build myself a proper house for my new godlike status: I wished to transform our old house in a castle, and that everyone remembered we lived there for our whole life.
I was going to wish for jewels and gold, when I wondered why I would need them! Well, the surer the better, I couldn't know, maybe a day the ring could lose its magic...
When I fueled a big room with jewels, I could return to the being once was my beautiful mom.
"I bet you're thinking how much times you could get screwed up with some of these." I stated, laughing, referring to the diamonds on the floor.
But mom couldn't care less. She was crying and trembling, asking to herself what I was going to do with her.
