"Nate is now my girlfriend," Zach whispered.
Suddenly time seemed to stand still. A pair of perky and palmable B-cup breasts pushed out of Nate's chest under his plain white tee while more profound anatomical changes were no doubt taking place beneath the diaper's padding. Her pant legs merged as they shortened into a salt and pepper pleated skirt, the hem stopping just a few inches above her knees. Her shirt turn a light purple and gained a pattern of darker purple shooting stars while the shoulders puffed out. Then the untucked shirt seemed to sink through the fabric of the skirt, the front and back wrapping around the padded bulk of her diaper until they snapped together. The backpack that hung from her left shoulder turned a bright red and various knickknacks like Sgt Frog and Lucky Star keychains appeared on the zippers. A few spare diapers with neon highlights were just barely visible in an open pocket. In that instant Zach's friend Nate was erased forever and his girlfriend Natalie was born.
She gave Zach a quick hug and a peck on the cheek. Her hair was still fairly short, barely enough for the ponytail she now sported. And the color was now a sandy blonde instead of the audburn that got Nate's shins kicked on a certain holiday.
"So, why'd you ask me over," Natalie asked a mischevious smirk.
Zach was so dumbstruck by the change that he almost didn't know what to say.
