She sells out her Team for her freedom.

"Wait- I can give you something better," Hyper-girl says.
"Better than a busty, Super-****," you reply, "I find that highly-unlikely."
"How about a Harem of Super Girlfriends- all slutty ones at that? You can't be satisfied with just me, right?"
"Go on."
"Please just take your cock out of my ass and I'll give you more than you could possibly imagine."

You look at her suspiciously, but do what she asks.

Before she can thank you, however, you grab a smaller butt plug and shove it in her wet asshole. She tries to protest, but your face says that you are serious.

"Well...I suppose you did keep your word in the most literal sense," Wendy/Hyper-Girl says.
"Just remember. That stays in as long as I require it to," you explain, "Barring understandable reasons, you will wear this at all times until *I* deem fit. Understood."
"Y...yes, sir."
"Now...what about your deal."

You tug on the chain connecting her nipple rings light enough to not really hurt her, but enough to show that you are serious.

"As you know, I'm on an all-female Team of Superheroines. I can set it up that you can play all sorts of dirty games with them- but we'd all get to still keep our powers and save the City."
"Interesting offer. Tell me who you're offering."

Hyper-Girl mentions several ladies on her Team, describing them, their code names and their abilities...

• Power Woman/Mrs. Samson. She's the oldest Member and Leader. She has super-strength, but is weakened by Diet Soda.
• Mirage Girl/Megan. She's a busty Blonde with the ability to project illusions. Her weakness is strong Incense.
• Hottie/Taylor. She's a tall, statuesque Heroine who can shoot Flames. Her weakness is **** Cold.
• Wonder Twins/Alex and Fran. Two short, but cute Heroines who join hands to shoot lasers. No power when apart.
• Golden Girl/Kayley. An amazingly-fit and cute Blonde. She can turn her skin golden-tough. Weak to Silver.

She's given you alot of options here. Do you decide to take one (or more of them) or keep Wendy?
