Hundred percent on board

Zoe turns her eyes towards you, looking haunted. "P-please. I don't understand what you just did but I accept your offer. I won't fight. Please let me be your ****. I'll be good... I want all of it. Everything you promised. I'll give you everything."

Wow, that went almost too well. What had you said, again? You can't be entirely sure, you weren't super focused.

Without giving it much thought, you pull out your phone and show her it's an audio recording app. "Give me something you don't want me to have. I don't care if it's even true. Make it good." You press record.

She shudders audibly and speaks directly into the microphone, clear as day. "Okay. It's me, Zoe, from 112 Sycamore street. I just graduated from Lincoln High last year... I masturbate to the thought of being ****. A lot. Specifically by my brother and his friends, but honestly I'd be happy with anyone. I'm such a filthy girl. Sometimes at school I would daydream about being fucked by Mr. Johnson on his desk and I'd forget to pay attention. Once I got dressed up and got a fake ID—"

You stop the recording, cutting her off. You're satisfied. "That's... some impressive leverage. You're serious about this."

"Yes. Please. I can't possibly cross you now. I wouldn't dare. That and the video you have would ruin me." She's trembling from arousal, all rage has vanished. "What should I call you? Master? Brother? What would make you happy?"

You smirk. She's clearly been exposed to a lot of porn or erotica to fall so easily into such a politely submissive persona but it works. To answer her, you simply return the vibrator to her crotch, buzzing at full strength.

She climaxes instantly, writhing in her handcuffs and moaning like a whore. You confidently follow her squirming body with the powerful little vibrator and **** her to endure three back-to-back orgasms as a reward for such complete and total cooperation.

After you remove the stimulus and she calms down, she manages a soft, "Thank you..."

Your glasses indicate she'd respond very well to some carefully measured **** right about now and suggests **** her face or punishing her breasts. You have perhaps 8 minutes until Natalie arrives, assuming she's on time.
