Jon followed his friend to the kitchen. He didn't have much choice. Mark had the stone so he could do whatever he wanted. What a stupid idea it was to hand him such a precious and powerful magical item.
As he entered the kitchen he saw some woman washing the dishes. A moment later Jon realized that this was Mark's mom just changed to match the description of his desire's voice.
Being already short before she shrunk even more standing only 5 feet tall now. Her frame was also very thin, almost child-like, but with two exceptions: her butt and her bosom. Even looking at her from behind Jon could see bits of her breasts sticking out from the sides of her slender torso. Then as he moved his sight downwards he could see her torso thinned a bit more in her lovely waist to then flare out spectacularly forming the most impressive posterior Jon had seen ever, both online and in real life. She was humming some melody and as she was moved her weight from one foot to another, just like women do, her huge hips were swayed in a wide arc to the rhythm of the melody.
"What have you done Mark? Look at her! How is she even supposed to function normally with a body shape like that?!"
"Oh, shut up Jon. It was your fantasy in the end..."
"But I'd never..."
Mark however wasn't listening. Instead he turned to his mother and ordered her do make him some cereal. He didn't even say please. He was a Fem-master now and apparently he didn't mind using power he had even over his own mother.
"But we don't have any milk honey. I'm really sorry Mark. I can go to the shop if you want..." Mark's mother seemed genuinely anxious about what he wasgoing to do.
"Oh, for fuck's sake! I want it NOW! You know what? I'm going to make sure we never run out of milk again!" he took the stone out of his pocket and said "I wish there was no need for cow milk because every woman lactated permanently amounts sufficient enough to feed their families. I wish that their breast size and shape remained unchanged, just their weight to increase slightly because... because... because I feel like it!"
There was a brief flash of light and after Jon could see again he saw Mark's mother smiling this time.
"You'll get your cereal in a minute." she said "I'll just go and milk myself. I had to do this anyway, mommy's boobies are getting quite painful, you know."
She left the kitchen moving in a way that made Jon's cock go slightly hard in his pants. How could that be? A creature clearly this kind of body must have felt extremely uncomfortable and yet she moved with such a grace and... sexiness.
"Mark! Why are you doing it to them? Women are people just like you and me! You can't just treat them like this!" Jon simply didn't know how to convince Mark to stop and he was getting definitely too far.
"Stop whining Jon!" Mark shouted "I thought you would enjoy it. I wanted us to have fun together. But no... You prefer to complain and whine like those very feminist bitches we were trying to punish in the first place. You know what? So be it. It seems that I'll be the only one having fun now! I wish you..."
