These are the original thoughts and rough concept that eventually became my Entrepreneurshipping fic. This isn't exactly how things ended up, but thought I would share them for the fun of it.
Siegfried and Leon are staying with the Kaibas while Seto is trying to work out the terms for buying SchroederCorp. They finally reach the point where everything is perfect except that Zieg wants Seto to sleep with him before he’ll sign the contract. That afternoon, they send the kids off to KaibaLand with Roland and the staff are all sent away. The boys get wine-drunk while “getting to know each other” and talking about Duel Monsters, and for a little bit, it almost feels like they’re just being friends. Then Seto tries to get Zieg to sign the contract again, and Zieg is like, “Look, I know your reputation. You’ve been making some pretty one-sided deals, and I’m not signing anything until I get what I want.” So they negotiate a little more, and then Seto sucks his dick with the agreement that they’ll fuck that night. They clean up and have a meeting with the attorneys to sign the contracts with proper witnesses and everything. Then that night they celebrate with a lot more wine in Zieg’s room, and Seto is an absolute DOM because he knows, from his own intuitions, Zieg’s confessions, and [redacted], that that’s absolutely what Zieg wants. They’re up fucking at least half the night, and by the end of it, Zieg is in love despite Seto telling him that this is purely business.
The next morning, Duke is hanging out with Seto’s assistant outside the KC building waiting for him to arrive. (He's running uncharacteristically late.) When he does finally show up with Zieg in his limo, Seto’s wearing dark sunglasses and doesn’t take them off when he goes inside. Those two are arguing in German, and Zieg gets a little touchy, so Duke is immediately like, “Why he touchin’ my man?” and goes up to him like, “Yeah, hi there, I have an important secret update on our project and we have to talk alone” and Seto tells his assistant to get Zieg set up in one of the smaller conference rooms and arrange a press conference for 3pm. Duke asks him if he’s hungover, and Kaiba’s like, “No, I’m not, shut up,” and Duke is all, “You made the mistake of drinking with a German. It’s not as bad as drinking with a Russian, but damn boy, I don’t think you know how to hold your liquor. You need more XP before you’re ready to go drinking against a German again.” And Seto’s all, “As fascinating as your knowledge of international stereotypes is, I thought you said you had something important to tell me, and that really doesn’t count.” By this point, they’ve made it to Seto’s office, and once inside he closes the door and starts closing the blinds. Duke’s all, “Oh yeah, the parts we needed for the next step have been delayed. It’ll be another two days before we can keep going.” Seto is annoyed and frustrated and sits down at his desk and puts his head in his hands. He’s still wearing the sunglasses. Duke asks about Zieg getting so handsy that morning, and what were they arguing about anyways, and Seto says that he needs Duke’s advice on how to get someone UNinterested in him. And Duke is like, “Oh, dude, no problem. But did you do anything that might have encouraged his affections? Cause I need to know that before I can say a word to him.” And Seto is like, “Well… you don’t need to know, actually.”
(following dialogue is the gist of what’s being said)
Duke: “You kissed him when you were drunk, didn’t you? I get it, he’s real pretty, but next time you get drunk, you should definitely invite me. I'm even prettier when you're drunk.”
Kaiba: “That’s not, ugh, you’re still flirting with me? Whatever, you’re hopeless. Is it really necessary for you to know what happened between us?”
Duke: “Yes, absolutely necessary.”
Kaiba gives him a thoughtful look and then Duke realizes.
“You slept with him while you were drunk, didn’t you? Now he thinks it means something?”
“That’s not… quite it either.”
“Okay dude, spill. You want help, and I can only do that if I have all the details.”
“I slept with him to close the deal.”
“He refused to sign the papers unless I slept with him, so” *casual shrug* “It was purely transactional sex, and he knew that, but by the end of it, he said he was falling for me, and I need him to get over himself.”
Duke is pretty shocked for a moment, and all he can manage is a quip. “I thought you didn’t date. But you’re good enough in bed that he fell in love with you after one night?”
“Shut the fuck up. I told you what happened. Are you going to help me or not?”
“Okay, okay, I’ll talk to him after the press conference and tell him you’re my boyfriend and that last night was strictly business, but he needs to back off now. Then you’re going to come home with me to make a point to him. Deal?”
“Fine, deal, whatever, just turn the light off when you leave”
