"What's your fucking problem Jen? Trans..."
"No no no! You can't use that on me! You'll obey me from now on. Oh wait! Actually, you WILL use it on me. But I'll be the one handing the rules" Jen was getting really excited with that. So many possibilities! "You'll ask me the question and I'll say Transform. You'll then repeat those exact words, without changing or adding or removing anything, understood? No need to awnser" Jen heard Kyle gagging as he tried to say something and was shut up by the curse.
"Jen, for your transformation, you'll become the hottest girl at the whole world. With natural F cups without any downsides, a huge butt and wide hips, and being able to change your appearence at will, any man or woman will lust after you, especially me. You'll have massive orgasms and amazing sex skills, and any cum you swallow will taste amazing. Any boy who fucks you will become your slave, still having free will but unable to disobey your orders. Say it now."
Kyle forcibly said what he had to, and Jen wad already getting off. When he was finished, she hung up the phone and started removing her clothes, not wanting to go to school, much less rip them apart as she grew. And boy would she grow.
Jen started feeling her chest expanding slowly, but the tingling was intense and pleasurable. She grabbed her right boob with one hand, while the other started fingering her dripping wet pussy and rubbing her clit. Jen moaned as she squeezed her breast and rocked her fingers back and forth with building speed. Her ass started expanding ass well, lifting her up little by little seeing as she was sitting or her bed. She send her boob caressing hand to her butt and gave it a good feel. Squishy, tender butt fat and muscle gave her shivers of pleasure and increased her lust, now wishing that her boyfriend was there to fuck her silly. "I will call him later" she thinks, while coming back to her boobs.
Now they were really close to their final size, and Jen went with both hands to play with them. As they became more sensible and full, Jen couldn't hold a loud scream as she squeezed them hard and reached orgasm. Her form was ready.
She stood up to look at the mirror. A goddess of sex stood before her, her heavy and sexy boobs hanging, while still perky. Her hips were as wide as they could, and her butt! Oh, her butt was a gigantic pillow, designed especially to fuck and fuck hard! Oh, her boyfriend was gonna be so horny, and Kyle was gonna be so jealous! Maybe she should make him watch it... "What a naughty girl you are, you slut! Hahahaha!" Jen caressed herself a bit more as she tried sexy poses and reached for the phone...
