Things do change a bit

Mil looked up at her sister

"Hey Mel..." She said in a mischievous tone "You've aaaalways wanted this haven't you?"

Mel went red

"Absolutely not!" She replied immediately

"Hm. Well, that's not what you're about to tell me. Tell me how much you love this"

Mel clenched up

"I've always wanted to be dominated by my sister" she sneered "I love the feeling of her tongue on my clit while I can't do anything about it. I love being a simple toy for her amusement."

"Ooh! Ciel! Now you!"

Ciel nodded

"the first time I saw Penny; all I could think about was letting her fuck me in any way she wanted. There's nothing better than serving my adorable teammate in any way she desires"

Jaune could feel the simple words affecting him, as his cock twitched inside of Mil.

Mil looked at her sister again

"hah... Alright my little sister slut... When I cum, s-so do you" she panted

Jaune wasted no time, slamming his fingers deeper into Penny, and ramming his cock into Mil.

The two girls cried out in orgasm, before a chain reaction made Ciel and Mel follow right behind them...
