The red one ofcourse!

You opt for the red one. Kiera is trying to complain but can hardly do more than stomp angrily. To mess with her you tighten the straps holding the ball in her mouth just one notch more. "Not happening. Get ready for some more."

You place your hands on Kiera´s shoulders and guide her into the living room. Once there, you pick up a pair of steep 8 inch heeled boots. Kiera seems grateful when you let her sit down in your sofa, but that changes when you´re pulling up the zipper on the first boot. She tries to resist the second boot by flailing the leg around. "Now now Kiera, calm down. I´m your Master now, remember?"

After zipping up the second boot, you picked up the last bit of restraints to add. You place leather cuffs just above her ankles, then you add a short chain between her legs. Even if she could balance properly, which she can´t, she´s now incapable of taking full steps.

Having restrained her to you liking, you sit down next to her and stroke her thigh and graze over her crotch. This makes Kiera moan on frustration, to drive home your point you pull her head to yours by the harness. "You like this, having no control?"

Kiera hesitantly nods, and you kiss her ballgag. You can feel it subtly move as she tries to push it out, seeking your kiss...
