"It's a loyalty thing, really," Pegasus tells him. He gestures vaguely with the wine glass in his hand. "You know what I mean, I'm sure, all good duelists do. Your best Monster, the one that always gets you out of trouble. Something develops, wouldn't you say?" And he smiles as if he's said something that makes sense.
Kaiba folds his arms. "It's disgusting," he says, "that's what it is."
"I know just what you mean." Pegasus pats his arm, ignoring when he jerks away. "He should be ashamed, cheating on his little, what does he call him, on his little aibou."
Now Kaiba frowns. "Don't be an idiot." Glaring at him, "he and Yuugi broke up months ago. If you ever bothered paying attention to anything besides your precious cartoons, you'd know that." Not that snapping at Pegasus seems to be helping his mood any. "The Dark Magician isn't even real." He scowls harder. "It's a card, a Duel Monster."
And Pegasus, who is very tempted right now to point out that Kaiba would jump at the chance to do it with a Blue-Eyes White Dragon, or, at least, to mention, casually, of course, that it's KaibaCorp technology that makes this whole thing possible, just smirks a little and says nothing. He sips some more wine.
Kaiba is still grumbling. "What kind of example does it set," he says, "what kind of precedent? How many duelists are going to start sleeping with their Monsters because of this?"
"I want to see Insector Haga with a petit moth." Pegasus cuts his snicker short under one of Kaiba's most withering glares. He also resists the temptation to speculate on how appealing Jounuchi might be with Celtic Guardian, and "why are you so interested in who Yami no Yuugi is having sex with," slips out instead.
"I'm not," Kaiba snaps.
"Okay, okay, you're not, my mistake," he says, and then, just to distract Kaiba, "let's fuck," he adds. "I'll pretend to be Yami no Yuugi, and you can pretend to be, well, yourself." And he isn't surprised when he's turned down, in fact, he's rather amused; but the bruises he nurses afterward, at home, with plenty of ice and a fresh bottle of wine, prove once and for all, for anyone who was wondering, that sometimes it can hurt to ask.
