"Pullups!?" You look down at your new Hot Weels underwear. "I'm still potty trained! Please, Claire, don't make me..." You stop as you both feel and see yourself start to pee, yellow liquid staining the underwear and running down your leg to pool on the floor.
Claire and the girls giggled, and Claire said "Guess you aren't such a big boy after all."
You realize a couple of things. First of all, these girls can do anything they want to you. And second, you sorta like being a little boy. This could be fun. You look around at the girls. "Could I have pullups with cars on 'em? Or horsies? Please?" You are surprised to realize the way you talk seems to have changed to a little boy's, too.
Claire squats down and grins at you. "I was gonna make you wear pink pullups with flowers, but since you said 'please,' I think we should reward you for good behavior. How about some pullups with the Toy Story cowboy on it? It has his horse, too."
You nod. "Sure! I like Woody!"
She goes over to an old carboard box and rummaged around. "I saw them in here somewhere... ah, here they are!"
One of the other girls giggles. She is Asian, probably Korean. "Those were my brother's. I found them hiddden under the his dresser. He still wets at night, and he's 15!"
"No wonder they are all stretched out. And used!" Clair shook the pullups and they seemed to shrink. "Now they should fit our nice little boy here."
You pull down your wet Hot Wheels unserwear and step out of them, and stare at your nub of a penis. The girls all giggle, and you think it's funny to be naked and giggle, too. Claire holds out the pullups, and you take them and struggle to get them on. They seem tight, but finally they are around your waist. Something seems a little different, though. And the girls all look amused.
Claire shows you the mirror again and you gasp when you see your reflection.
