A tiny penis!

"WAHAHAHA!" "PWAAHH HAA HAA!" "PPFPBWAH! WHAHH THAT'S SO SMALLL! HAHAH!" All her friends laughed and pointed.

"Oh my god no wonder he's a virgin, besides the diaper, and everything else! Wow he's pathetic. Even if he could use a big boy potty he'd never get with a chick!"

"Yeah that's just, wow. I'd feel bad for him if he wasn't dumb brat! Ha! Pinky, you have a small penis!"

Helen smugly smirked and undid the cuffs keeping him bound. "Wow. You didn't pee yourself, Pinky! Congratulations!" She checked hia diaper then turned to her friends, "He often pees in his sleep but he went a full week without wetting the bed!"

He covered his penis with his hand as soon as Helen undid one of the arm straps, and she yanked it away then slapped his inner thigh.

"No touching yourself, you'll get a spanking if you do that again!"

"AhAhahHA! Pinky! You're getting scolded by your sister, she can give you a spamking and she's your younger sister! Wahahaha that's awesome. You really are such a baby!"

"Yeah. He really is, with that tiny thing."
