A little bit of both

Jaune sent Weiss a quick text.

"Are you close?"

"Yeah"

"Find somewhere to hide, wait for my signal, then come in. I need to talk to you."

Jaune waited a few moments...

"Finger each other" Ciel said. Yang and Blake, still making out, inserted their fingers into one another, and Jaune pulled out the book.

"Weiss Schnee's hair will turn black, eyes will turn green, breasts will grow two sizes, and ass will inflate a bit. This effect will leave when Jaune Arc says 'No more hiding' and will return if he says 'snowflake in disguise'"

Jaune waited again

"SERIOUSLY?!" The text came in

"You needed a disguise, right? Now come here"

"Now orgasm!" Ciel boomed, as the two began to moan and whimper.... And so did Mel, Jaune noticed, as he looked up at her.

"Alright Ciel. That's enough. For the next 10 minutes you'll be a dog." He said

Blake and Yang tumbled over onto the floor, Yang on her back, and Blake on Yang, using her tits as pillows as their orgasms faded.
