The condescending smile poorly hidden under a teacup rim did nothing for Zoro's irritation levels. Robin placed down her drink and laid her chin against her propped up hand. "Your sense of direction is so bad you couldn't even find your way to the proper summoning page?"

Zoro had just recapped the events that had transpired, and Robin was giving him the look you give to an animal that just just did something cute but stupid.

"Just tell me how to get rid of him!" Zoro snaps irritably.

"Make a contract" Robin says simply.

Zoro groans, "I already told you, I'm not going to let some monster pray on and use someone, while they eat them. That is disgusting."

"Everything has to eat." Again she speaks as though everything is simple.

"Yeah, so maybe the demon doesn't have a choice about what it eats, but I do! If I had him do that I would be the one who is a monster."

"I'm sure some people wouldn't mind that kind of thing. Sounds like you find him desirable enough." That damn knowing look again.

He realty doesn't want to be having this conversation right now, "He's a succubus, of course the guy is fucking sex on legs. If I could I would choose to never look at his stupid ass face again though. Regardless if someone agrees to have them feed off them I'm still the one feeding a person to fucking demon. They shouldn't have to pay for my mistake, even if they don't mind."

"So noble. Why not have him feed off of you?"

Zoro crosses his arms, "He doesn't like men."

Robin chuckles softly, "I don't like certain food either but if it's my only option and I'm hungry… well I don't have much choice in that matter, do I?"

"This is different though…" He studies her face, and she's still giving him that look like he isn't grasping something, "Isn't it?"

"Let's put it this way" Robin leans back in her chair clasping her hands together in her lap. "A cheque is a piece of paper that states you will pay something regardless of what is written in the memo line, correct? A contract is similar to that. Think of it this way, Sanji's contract is like a blank cheque for sexual energy. It's up to you to fill in your price. He already handed it over for you to fill out."

"My price?" Zoro asks.

"What you want. Regardless of that he says, that contract might as well be legally binding. It doesn't matter what he says, you have the power here."

He hadn't realized that but it made sense. He was the customer and had to pay either way, so he gets to choose what he wants.

"Will he let me sign a contract like that?"

Robin softly chews her bottom lip, "Well he can't exactly stop you, but you don't want to purposefully anger a resident of hell either."

Zoro knows she's trying to warn him, but considering she's worried about him getting hurt by some pretty boy demon is pretty insulting.

"I don't care if I piss him off, he doesn't scare me. As a matter of fact it can be a nice warm up before I summon Mihawk."

She looks a little worried at that, "I suppose if I find your body ripped to shreds and splattered on the walls at least I would have some comfort in knowing why."

He really hated it when she said creepy shit like that, "How do I fill out a contract anyways?"

That damn knowing smile was back on her lips again, "Oh my, are you telling me that you went into this so blind that you don't even know that?"

"Just tell me."

"You can either summon him and tell him, or fill out the contract yourself. You can summon him or your contract at any time until the contract is completed."

If Zoro had been drinking anything he would spit it out right about now. "I can do that?"

Robin tilts her head to the side, her long raven-like hair cascading down her shoulder at the motion. "You really should have listened to me and done your research beforehand."

"Could you please just tell me what I need to do?"

He is grateful they have been friends for so long that she lets his snippy comments slide right off of her. "All you have to do is call on him or the contract and present his symbol at the same time."

"His symbol?"

"Yes, most demons have it somewhere notable, most of them on their face. Something that stands out about them."

"He has stupid swirly eyebrows like this" Zoro draws the swirl of Sanji's eyebrows in the air with his finger.

"Perfect, now say, 'I summon my contract between me and Sanji' and make that gesture in the air again."

Zoro feels kinda dumb but shrugs and does what he is told, "I summon my contract with Sanji" he traces the design of Sanji's eyebrow in the air.

Before him in a flash of blue light is a contract.

It is actually really straightforward to Zoro's surprise, it just says that Sanji gets to consume as much energy as desired without causing bodily harm for as long as it takes to fulfill the contract. Depending on the quantity and time it takes to fulfill the contract will be compensated by extra sexual energy. It also explains that he can not affect anyone other than the desired target(s) that is placed on the contract.

"So if he eats off of me, then we can call it good, and he goes away."

"Technically yes, but we must look at this carefully and fill it out properly"

"Perfect" Zoro starts to write before Robin can stop him.

Across the payment line he writes his name in large print, before signing the bottom.

Robin looks at what he wrote and her eyes are as large as the saucer she uses to place her tea cup on, "What have you done?"
