Use it! But also...

"Man. Yang is so great" Jaune mused aloud. Ruby got a look on her face, looking almost offended.

"Hey! I'm great too ya know!" she huffed, before tossing off her clothes and leaving herself clad in only her underwear. They weren't exactly the most flattering - just standard black undies - but it was the best she could do to mimic Yang's bikini at the moment.

She then stood beside Yang and posed. It was more of a cutesy pose than anything, standing there winking with one arm up, and the other on her hip.

Jaune then smiled and walked over to Yang.

"Repeat after me" Jaune said before whispering something in Yang's ear.

"I'm a big boobed bitch who is built for breeding" she purred.

"Aaaand loop"

"I'm a big boobed bitch who is built for breeding" she repeated over and over again. Ruby made a pouty face.

"U-uhhh... My name is Ruby, check out my boobies!" she declared, as she shimmied side to side, making her medium sized breasts jiggle a bit. It was nothing compared to Yang, but Jaune had to admit he never really noticed Ruby's figure before. Her usual attire wasn't exactly flattering, but she did have some perky tits and a cute little butt. Even so, his eyes were far more drawn to Yang as she cupped her massive tits and seductively cooed about him breeding her over and over.
