Have her and Katara play a bit!

"You know what you should do, Master?" Aza asked, placing her hands on David's shoulders, and making him pause as he considered her words.

"What do you have in mind?" he asked, turning to look at her. She grinned and looked between Samus and Katara.

"Since Katara picked Samus... Shouldn't they get to play together a little bit?" Aza proposed.

He blinked, before smiling. Samus certainly seemed game for it. "That's actually not a bad idea..." he agreed, eager to see that particular show.

Katara then pouted at Aza. "You just want us out of the way for a bit so you can have Master to yourself for the duration," she accused playfully.

Aza stuck her tongue out. "Well, maybe just a little bit," she replied. "But you should know, I'm always happy so long as Master is pleased. It doesn't matter who he's fucking so long as he's having a good time."

Right. It's just a nice bonus when it happens to be you in particular, right?" Samus asked, and Aza giggled.

"Pretty much, yeah," Aza nodded. "But are you two really going to say no to getting to have a little bit of fun with each other?"

Katara and Samus exchanged looks. "...darn it, she's got us there," Katara nodded, before leaning in to kiss Samus, who moaned as she cupped Katara's face and returned the kiss.

Samus then broke the kiss, and added, "True. Funny thing is, we know she's playing us, but she's right..." They proceeded to begin feeling each other up.

Aza giggled, and turned to David. "So... Master," she crooned, leaning in and cupping his chin. "How do you want to use your genie **** now?"
