Brats

You turn a corner and approach an intersection. The light is against you, and though you could easily change things, you just stretch and enjoy the feel of the sun and the warm day.

"Oh my god!" comes a whiny feminine voice from behind you. "Guess what I'm getting for graduation."

"A car, you told me," said another female voice.

You turn and see too girls who look like high school students. One is a blonde and one a brunette, and both are very pretty. One is wearing a pair of tight jeans with holes in the knees, and the other is wearing a short denim skirt.

"A fucking Hyundai!" said the blonde.

"I thought you were getting the Mini convertible!"

"I know!" said the blonde. "A Hyundai! I like don't believe it! It's bad enough we have to stay in a dorm our freshman year."

"Well, that's my parents fault," said the brunette. "Like we have to prove ourselves before they pay for our apartment."

You turn and roll your eyes. The light changes and the girls walk past you. In a flash, the girls' jeans and skirt disappear, and now each is wearing a diaper. Thanks to you, neither will realize how she is dressed or what she is wearing until they get home. No one would say anything to them about it unless someone at home noticed. Once they realize how they had been walking around, they will feel like complete idiots and have no idea why they were dressed like that. Not only that, but as long as they are roommate, they'll have a fetish for wearing diapers, wetting them, and changing each other's diapers and do it at least once a week.

You follow along after them and watch them ignore the strange looks they are getting. You are rather horny now.
