Offer her a way out for her developing addiction

You chuckle, the sound low and resonant against her chest, but you don't move toward the bedroom. You keep her at arm's length, enjoying the way she practically vibrates with need.

"If I'm just the peddler fulfilling your addiction," you muse, tilting her chin up so she has to meet your gaze, "then we need to talk about the price. A high-grade 'fix' like this isn't free, Kurenai. And a shinobi of your caliber knows that every transaction has a cost."

She swallows hard, her pulse visible in the hollow of her throat. "What do you want?" she whispers. "Money? Information?"

"Money is boring," you counter, a predatory glint in your eyes. "But maybe I should charge you per... session. If you want to feel that way again, you have to earn the right for me to come back. That means you need to keep working. Keep being the elite kunoichi the village expects."

You lean down, your lips ghosting over hers without actually touching them. "But we have to be smart about the 'dosage.' I can't have you going on an S-rank mission to the border. Imagine the withdrawal kicking in while you're deep in enemy territory. You’d be useless—shaking, distracted, dreaming of me while a kunai finds your throat."

Kurenai’s eyes flicker with the realization of how dangerous her situation truly is. She is a liability now, tied to the chemicals only you provide.

"So," you continue, "nothing high-profile. Stick to B-ranks, maybe a low A-rank close to home. You go out, you complete the mission, you bring the bounty back to me as a tribute, and then I give you your fix. It keeps your skills sharp and ensures you don't lose that 'jagged' edge I warned you about."

You let go of her wrists, stepping back just an inch to see if she will collapse or crawl toward you. "Do we have a deal, Sensei? Or is the price of your addiction getting too high?"
