Deny her. Ensure her cooperation

...and you withdraw the buzzing little toy.

She groans into the gag, struggling pointlessly against her cuffs and your weight. Her feet kick uselessly against the floor. There's nothing within her reach to give her leverage.

You watch as she shuts her eyes and clenches her thighs together in a **** attempt to salvage the orgasm, but she fails and you laugh out loud.

"See? There's no use pretending to be so pure and innocent; I know I'm right about you. That you secretly touch yourself thinking of someone taking you against your will. Someone big enough and strong enough to actually **** you because you've grown too capable of defending yourself. You can't just let it happen, either. It has to be like this. Doesn't it?"

Her face is bright red and not just from the slaps. Fresh tears of humiliation gather in her eyes.

"I'm going to make you an offer right now, and I'm only going to make it once so listen closely."

Convinced you have her entirely undivided attention, you continue, leaning heavily on the information coming from your glasses, speaking without thinking about the precise words you're using. Guiding the entire conversation as a manifestation of your desired outcome and letting the glasses fill in the gaps.

"You don't know how or why this is happening but you don't need to know. It'll be better for you not to know the details. Just know that your big brother has leveled up and now you're going to be his ****. Don't make the face. The idea turns you on. Deeply, powerfully. You don't need to fight the feeling. And it's better if you don't, because you don't really have a choice anymore. This is happening. If you fight you will lose and you'll only make it worse for yourself. You're thinking right now that you can find a way to free yourself but you can't.

"The deal is this. You give up all pretense of your innocence and accept that this is your life now. You freely give me more and more leverage over you to ensure you never defy me again. Become my accomplice in enslaving you, and I will make all your darkest, most shameful fantasies come true for you. If instead you reject this offer and resist or undermine me, you will still be my **** but you will suffer for it. There's no need to do that to yourself. You can have everything you want and it can still be our little secret. Our dirty, delicious secret.

"I know you're thinking it will be more fun to fight, to make me **** you at every turn. Consider yourself ****. Submit now and you will experience the thrill you seek. There is no other choice... No, you don't need to know. There's a good girl. Yes. Yes, really. No more fighting, now. Let this happen. That's right. No, don't worry about that; I'll worry about that."

You continue speaking on autopilot as your thoughts drift to a brief fantasy of her as your obedient little ****. **** to please you, to serve you. To betray all her friends and morals for you. It's hot, and you're once again reminded that your cock is still yet to be serviced. Eventually you realize you're still speaking but haven't the foggiest what you've been saying for the past few minutes.

Zoe's eyes are glazed over like she's staring very far away. Her breathing is fast. She nods softly, with tears on her cheeks.

You pull the gag from her mouth. "Well?"
