Anna stared at herself in the mirror.
She wore tight black gym shorts and a sports bra for her underdeveloped breasts. Half way through her pose for tomorrow's photo-shoot, she realized that something was coming for her. Looking at her body in the full length mirror she looked at her small breasts, her hands roaming from her doll like face, down her swan like neck to her breasts.
They felt alien, a prop, on her body as the other hand went down to her vagina. She felt that something was wrong. Something was missing, something HE had had since he was born, before then a...a...penis. As that though formed in her head he started to remember have a penis and using it, both with his own hand and recently with other women.
As these male sexual thoughts took over Anna's mind the panties suppressing Ben's penis and male form started to struggle. Like machinery overheating from the pressure placed on them.
"Ah! OH..." Anna gasped.
Her vagina started to close up and form in a flat space before a tiny bump on the front of her panties. Then a wet spot appear as some liquid came out of the new appendage, leaving a wet spot between her legs. She opened her thighs to accept his rightful limb being restored. Anna ripped off her gym shorts to see her backside was that of a mid-teen fashion model. But the fabric of green satin panties created a piece of fabric between the inside of her thighs, as Ben's baby cock grew into that of a toddler then a boy and finally a teenage male, who had used it to get two women pregnant.
He still had the bubble but that was barely covered by the panties but now he could see the green fabric trying to suppress his gender. Ben grabbed a pair of scissors and tried to cut them off, but he yelped in pain. It was if they were fused to his body, even his soul. He let his growing strength make his hips crack wider, making them more like a young boys. the smooth descent to Anna's pubic mound was gone as s/he started to squeeze his eyes shut and focus like taking a crap or giving birth.
His legs became more developed and hairy as he turned into Ben's male form. With disgust he kicked the enchanted panties, thinking of them as cursed, to the ground. A teen male from the panty line down his top was still that of Anna's. Those budding breasts, toned stomach, Slavic-doll like face with pouting lips and long thick shinning brown hair.
"You are not me, you are Chinese magic and I rule that."
His breasts started to deflated, having recently crossed into B cups, until he had the wide chest of a 14 year old, but the nipples of 10 year old. Squeezing his eyes together the matching tube bra that had given Anna's breasts their size and shape was exposed. He again tried to rip it off him, as well amputate his own hand. Slowly the fabric spread to show the thing that had latched onto his sleeping form.
Exposed the magic broke, his hands returned with thicker, hairier hands, muscles developed with the sudden backlog of testosterone being restored to his body. As the long brown hair fell off his head, vanished and was replaced with blonde regrowth. Slight facial hair appeared on his face as it went from that of an elegant Russian peasant girl to that of a young Nordic teen. Eyes burned as they turned from green to blue.
Vomiting on the floor his male body was rejecting the internal organs that Anna had needed, and would continue to do so for the next few weeks. Remembering Heather with her flowing red hair he started to develop a hard on. Now nude he looked at his engorged penis:
"Time to fill the void." he smirked at his own joke as he grew harder.
Jacking off didn't seem to stop the repressed ejaculations Sofia's panties had suppressed. He knew now that Ms B and she were pregnant but he would had to confront her first, using Heather.
