Yes, she's your play thing.

Ms. Samson finds that her super-strength is gone and fighting against Hyper-Girl is like an infant trying to push away its Parent. You lock the cuffs on her, rendering her athletic arms immobile.

"What is this? Why are you doing this, Wendy? HOW are you doing this," she asks in quick succession.

"To answer the first question, I'm tying you up to make you my sexual plaything," you reply, grabbing both of her tits.

She struggles as you fondle those lovely mammaries that you've only dreamed about. Wendy covers her mouth too.

"To answer the second question, she has a good reason. I captured her and gave her a choice- be my powerless **** or be my powered subject. She sold you out...Power Woman."

The Coach issues many muffled statements against Wendy's super-strong hands, but they are smothered.

"That's right- I know who you are. I know who *all* of you are," you say, pulling her lovely tits out of her tank top, exposing them.

You **** the Coach to stand up and move one hand to cover her lips. You order Wendy to use her Hyper-powers to disrobe her Leader (on both Teams). Still having an ass-full of the glass plug in her, she obeys.

Within seconds, Ms. Samson is completely naked, her top and bottom somehow torn apart at super-speed and precision.

You use your Reality-warping powers to make Ms. Samson be a secret Submissive. With her great Strength, she always yearned to be controlled. Nobody has been able to do it, making it a sweet taboo for her. You also give her a nudge to be more attracted to Wendy/Hyper-Girl, although you don't need to do much. I mean, she's hot as hell!

"So here is the same deal that I gave Wendy here- I can break you with orgasms until you are nothing but a weak **** OR you can be my slut and keep your powers. What do you choose?"

You could honestly go either way with this. If she chooses to be your ****, you could always just give her new powers, after all.
