Just as the transformation had occurred and Mandy looked on, she quickly realized that the diaper that Jeff had been transformed into looked like it was just in her size. It’s designs were a bit more babyish than what the girl donned, but it would still be serviceable. Mandy bent down to observe the object that was formerly her brother.
“It really worked!” the incontinent girl gasped, “Jeff’s my diaper now!”
Mandy thought about undoing the change for a few seconds. After all, being a diaper would be an horrendous form of torture.
“Nah!” she said to herself, “I really wanna wear him.”
Meanwhile, Jeff was in shock. He was just about to enter his room, only to find his sister locked the door. He struggled to get it open, and when he did, he was engulfed by a bright light. The next thing he knew, he was stuck laying face-up and his sister was looming over him.
“Mandy must’ve used the Chronivac! What the hell did she turn me into…” he thought before the girl audibly gasped at having transformed her brother.
“Diaper?” the transformed boy thought, “But Mandy doesn’t wear…”
The effects of Mandy’s Chronivac alterations of herself suddenly kicked in, and Jeff started recalling memories of his sister has a condition that left her incontinent.
“Oh no!” he thought, “Mandy’s gonna use me!”
The gargantuan girl grabbed her brother, and picked him up. She brought him up to her face, and took a large whiff.
“Ahh,” she sighed with relief, “Your perfume will cover up my messes real good Jeff!”
The transformed boy tried to formulate a plan of escape, but was rendered immobile by his new form. Mandy carried him out of the room, and into her’s. It had all the trappings of a normal girl’s room, just with a pack of diapers by the bed and a diaper pail next to a desk. The girl laid her victim on the bed, and unfolded him. Jeff heard tapes rip as Mandy took off the diaper she was wearing.
“Wow, I didn’t even use this one!” she remarked, as she balled it up and tossed it into the pail, “That means you’re in for a bad time.”
A pit formed in Jeff’s (metaphorical) stomach. Then an immense weight smashed against the diaper-boy as his sister sat down on him. His front and back were brought up, wrapping around Mandy’s waist. Then his arms and legs which were now the diaper’s wings, were stretched around his sister’s hips, and taped together.
“Mandy!” Jeff tried to yell, “If you use me, I’ll make your life Hell!”
His attempt was fruitless, as diapers had no mouths to speak. Mandy draped her skirt over her brother, completely blinding him. Then she stood up, and walked out of the room.
“What do now?” Mandy thought aloud.
