Very sexily.

"Ruby says," Ruby grinned. "Do jumping jacks!"

"Okay, that's fun enough!" Yang said, starting, and being joined by Blake, Glynda and Celestia. It seemed like a simple silly one, but then Jaune saw their flesh bouncing quite nicely.

"Okay, you can stop!" Ruby said quickly after about ten. However, they kept going. "I said you could stop..."

"I wasn't born yesterday Ruby," Yang smirked, her boobs bouncing with every jump. "You'll have to do better than that to get us out!"

"Poo," she said. "Okay, Ruby says, stop." They stopped. "Ruby says spank yourselves three times each!"

"I just got done being spanked!" Glynda whined as all four obliged, the smacking sounding out, their butts bouncing.

"Ruby says play with your boobs!" Ruby grinned, and they all cupped their breasts, toying around with them. "Ruby says, call yourself some kind of slut, like you mean it!"

"I am such a silly slut," Yang grinned, continuing to play with her tits.

"I am a total slut!" Blake said enthusiastically, though it was a bit ****.

"I am a sexy slut," Celestia added, lolling her tongue out in a seductive manner.

"I am a hot teacher slut," Glynda added.

Jaune watched with great enjoyment as he got hard.
