5’6”

“Liz, you’re now 5’6!”

Liz silently thought she must be growing 2 inches every time she masturbates.

“Wow! I’m taller than some of my classmates now!!” Liz giggled exitedly.

“Congrats, glad to see yo...” As Josh was speaking he was panning up from the tape measure up his sisters body to look at her face but got cut off when he panned to her crotch. Due to Liz’s tighter pj’s her bulge was prominent. Josh hadn’t noticed anything til now because he was focused more on Liz’s height.

“Um Liz, what’s that bulge in your pants?”

Liz swiftly moved her hands to cover her crotch.

“Nothing!”

“Liz come on what’re you hiding in your pants?”

Liz was embarassed but let her guard down a bit, “It’s...what I’ve been using to get taller..”

“Liz are you taking growth hormones!” Josh asked concerned.

“Nono! It’s nothing like that.”

“Then show me what your hiding”

Liz knew she could trust her big brother with her secret.

“O...okay but don’t tell anyone. And with that Liz moved her hands to her sides and pulled her pants down,

Josh couldn’t believe it, between his little sister’s legs was a dick, and not a small one.

“Liz when did you, how did y”

“I Don’t Know” liz interrupted , I know it sounds crazy but it just appeared and now everytime I cum, my boobs get bigger, I get taller, and she grows more.”

“She?”

“Yes my cock is a she! Got a problem!”

“Nono sorry, so um, how big is ‘she’ now?”

“I don’t know, I haven’t measured it.”

“Well, we’ve got a tape measure, I could um, measure it for you?”

This was Josh’s awkward attempt to support his sister in such an odd situation.

“Well okay”

Josh grabbed the tape and walked over to Liz, “can..I hold it?” A small part of Josh was doubtful of this clearly real dick but wanted to teat it nonetheless.

“Sure” liz replied.

Josh got to his knees held the soft cock in one hand the tape in the other and measured.

“She’s”
