Three babies on the bus go round and round.

"C-Crystal, what's going on?" Asked the second girl. Crystal got up and walked toward her, having a vacant and distant look in her eyes.

"Come on Kiki," said Crystal. "Your mommy will get vewy angwy when she sees your not in a diapie. Good girls always wear their diapies."

"I'm not a baby! Your not a baby! Whatever she did to you try to fight it!"

Crystal gave a babyish giggle when Kiki fell back, having been back up to the very back of the bus. Before she could move to the side in hopes of escaping, Crystal grabbed her hands and put them above her head. Crystal gave her an excited look before she closed the distance between their faces.

Kiki made a shocked noise, muffled by their kiss, feeling Crystal's tongue trying to touch every inch of her mouth. Their kiss separated, Crystal liking Kiki's outer lips before pulling away.

"WHAT WAS--" Before she finished her statement, her whole body blinked a bright pink before is began to transform. Her blonde-hair tied itself into two matching pig-tails on the side of her head. Her school uniform vanished, her white panties swelling into the form of a diaper before clothes manifested on her body. On her body formed a t-shirt and pants in a matching lavender, her new diaper poking out the top by a noticeable amount. A lavender colored pacifier appeared in her mouth before she started sucking on it.

Joanne and Crystal both jumped up and down in excitement over their playmate. Kiki watched them jump as she sat their, sucking on her pacifier. There was a loud hissing noise followed by a muffled, squishing noise, indicating that hidden under her new toddler-trousers, Kiki was peeing and pooping her new diaper.
