When Rudy made that last remark he started to change by having his red hair grow down to his waist and soon his frame turned into that of a girl's.
"Oh my!" Rudy exclaimed noticing that he was starting to become a girl.
"You must have a delayed reaction time." Sarah said. "I bet it's because your pj's contain some sort of blocking device but only a little bit of one, time i did something about that."
Sarah soon took the pj's off Rudy and despite Rudy only being eight he grew the largest breasts in the town at an N cup with his nipples becoming more sensitive and his face becoming more girlish, one of the lucky ones who got larger than an E as he let a moan escape as he examined his new chest. "Ooh! That feels good."
"No fair, how come you're bigger?" Sarah asked. "You aren't even old enough to have buds."
"It's a reward for boys who slowly accept the change." Their mother remarked as she soon fixed a light purple bra around Rudy's chest. "This will keep you from having to adjust so much, oh and it's strapless so it won't give you trouble."
"Thanks, but it's embarrassing looking like a girl with a boy's package." Rudy replied realizing that would soon change as he felt his special organs shifting into girls and the need to drop his briefs as his jewels had turned into a slit as his mind soon became a girl's when he put on the panties that matched his bra, and it was a good thing there was a pad in them because unlike other boys his age that transformed he was starting to have a period and so he now she instantly rushed to the bathroom.
