Turn Sophia into a living sex doll

You turn on the pheromones and flip one of the promising settings.

Immobilizing: ON

You're curious as to how exactly it works, but you figure you don't need to wait long. As Sophia continues to stroke your cock, she looks up at you curiously. "What did you do?" You smile down at her. "You'll see." She grins mischievously and fixes her eyes back on your cock. You notice that her stroking is slowing down. "Issssittworrrkinnn...?" Sophia tries to speak, but her words slur. She's losing control over her motor capabilities. Her eyes dart around, but her body seems to slow down. She lets out a groan that might have been a question, but is completely unintelligible.

You chuckle to yourself. "That worked a lot faster than I expected." Sophia looks up at you, looking for an explanation. "You see, I've had a thing for you for a long time. And now, you can't stop me from getting what I want." Her breathing quickens. She starts to move a bit and you feel like she's fighting the pheromones. "Oh, we can't have that..." you say, before grabbing the sides of her head and guiding her mouth around your cock, letting it slide down your length. "Fuck..." you moan in pleasure as her lips reach the base of your cock. The effects must have also removed her gag reflex, as the head of you dick reaches past the back of her throat with no reaction. You let her sit there for a moment before pulling her head off. You can hear a sharp intake of breath as she inhales, but don't give her long before you start rhythmically bobbing her head on your cock.

"Mmm you're a perfect little toy..." you moan to her. "I'm going to enjoy this."
