Ever wonder why Gunter is constantly all over Yuuri? This is my explanation .

Kyo Kara Maoh is NOT mine! After all, Gwendal and Gunter haven't had sex in the actual series. Do you think I'd let it go that way?

The Bet

"So all I have to do is sleep with Yuuri and I'm seme for a year? Gwendal, I hate to say it, but you're fucked. Literally." Lord Gunter von Christ mused silently as he drifted off to sleep.

He and Lord Gwendal von Voltaire had been an item for almost four years. Everything typically ran smoothly, but every so often an argument would break out. That night was not only the end of the day that His Majesty, the great Demon King had finally arrived, but also the night of a fight between Gunter and Gwendal. Gunter had been on bottom for over two years and wanted to be on top again, but Gwendal refused.

After a long argument and losing the desire to have sex, Gunter came up with an idea to settle the matter. Whoever could have sex with the new king and prove they'd done so would be seme for a year. Gwendal accepted the bet and they went to bed, backs to one another as if to prove they wouldn't back down.

--

The next morning, Gwendal had nearly forgotten the bet. It was vaguely in his memory, but he wasn't worried in the least that he would lose. The idea slightly annoyed him, and he didn't really even want to try. He was sure Gunter wouldn't succeed either; after all, Yuuri was already engaged to Wolfram. Had he known how badly Gunter wanted to be seme, he would've thought differently.

Gunter's cries of "Your Majesty!" echoed through the halls. Nowhere was safe for the new king. Gwendal sighed. He was stupid to accept the bet. He should've just bent over last night. Hell if he was telling Gunter that, though. His lover was being annoying, that was true, but he also had pride, and wasn't going to sacrifice it just to get Gunter to shut up.

Weeks went by and Yuuri came and went between the two worlds. A couple times Gunter got dangerously close to completing the task, which sent Gwendal into a panic. He had been sent along with Conrad and Wolfram to help Yuuri retrieve the demon flute. He almost slept with Yuuri then, but couldn't bring himself to do it, especially after finding out the repulsive fact that Yuuri doesn't like small animals!

"What's the harm? Gunter won't succeed. He's being clingy and scary, not attractive" Gwendal muttered as he went to sleep in the tent. Unfortunately, Gunter had a lot more knowledge of what would and wouldn't work than Gwendal thought.

One morning a few months later, long before anyone was awake in the castle, Gunter was preparing himself to finally complete the task. He was tired of messing around. He missed Gwendal, but wasn't about to go back to him without having successfully completed the task that had been betted on. He was far too proud for that…not to mention sick of being on bottom.

The ivory-skinned man was putting on some make-up that Yozak had given him-nothing too girly, just a little foundation and a bit of mascara and eyeliner to bring his eyes out. He took two vials of liquid from his nightstand; one cap labeled "A" for "aphrodisiac", the other labeled "L" for "lubricant". Anissina had given him these.

Gunter was happy to discover that everyone in the castle that knew about the bet-Anissina, Yozak, and the maids- were all cheering for him. He figured a certain trio of maids, Doria, Sangria, and Lasagna, had been spying when the bet was made, thus the news getting out. It seemed to be playing in his favor, though, since neither Yuuri nor Wolfram knew, and he'd gotten so much encouragement from everyone that did. He'd gotten several letters wishing him good luck…some racier than others, some describing what he should do with Yuuri, others what he should do with Gwendal once he'd won. A few were sane, but most were quite dirty. He was sure he had multiple raunchy ones from Yozak. He was mainly thankful for Anissina's gifts, however. He'd been considering asking her for an aphrodisiac, but didn't want to leak information about the bet. Since the information was already leaked, he didn't have to ask.

Gunter glided stealthily down the halls in the pale morning light, making his way to the room Yuuri had been sneaking off to sleep in late at night as an escape from Wolfram. Before that he had gotten a cup of warm tea from the kitchen. He poured the aphrodisiac into the tea and stirred it carefully, then carefully pushed the door open and slipped into the room.

He closed the door and locked it before gazing about the chamber. Yuuri was sleeping in the small bed that the spare room contained, oblivious to the world and snoring slightly. Gunter groaned inwardly. This would be rather difficult. Yuuri was still a boy! There was nothing sexy about him, not at all like Gwendal, but this had to be done. He took the aphrodisiac from his pocket and noted that there were still a few drops of the potion in the vial, as he had planned. That was a very good thing, as he was sure he would need it, as well as the most arousing mental images of Gwendal he could conjure, to make this task possible.

There was one last item needed before Yuuri would have to be awakened. Gunter pulled one last vial from his pocket; a small, rounded jar with a cork in the top. It appeared to be empty, but it was the most vital item of all, as it would serve as the proof of what was about to happen. He uncorked the vial and muttered a short incantation, which seemed to cause a slight breeze in the room. He placed the vial on the nightstand next to Yuuri and proceeded to swallow the last of the aphrodisiac.

"Now to wake up Yuuri and get this over with" Gunter whispered to himself. He glided to the bed and removed the blanket from the sleeping king.

"Nmnmgh…what…who's…not now, Wolfram…" Yuuri groaned, forced awake by the chilly air.

"No, Your Majesty, you haven't been discovered by Lord Wolfram yet" Gunter said with a sweet smile.

"Oh, Gunter! Thank goodness it's not Wolfram…if he found me here I'd never get any sleep again…what time is it?" the king responded, still not fully awake.

"It's still relatively early. My apologies for waking you, but I needed someone to taste this tea that I made. I need to be sure it tastes alright before I give it to Gwendal…he's been asking for tea for a while and I want it to taste okay, but with my cooking ability…" Gunter lied effortlessly. He'd had to fabricate so many lies in his lifetime that this was simple. He held the spiked tea out to the young king.

"Oh. Uh…okay…" Yuuri answered, still groggy. He took the tea, sipped it, then downed the rest in one gulp.

"It's perfect! Tastes wonderful…and woke me right up, too!" Yuuri exclaimed. Gunter noticed the king's eyes beginning to get hazy.

"Wow, that aphrodisiac works fast…" Gunter thought. He was forced to cross his legs so Yuuri wouldn't notice the growing bulge in the adviser's pants. This would have to be taken slowly…

The two chatted about random nonsense for a little bit, both becoming more and more uncomfortable thanks to the effects of Anissina's potion. Finally, the dam burst.

"Is it…hot in here?" Yuuri asked timidly. He was sweating a bit and his face was flushed. He allowed the blanket he had wrapped around him to fall off his shoulders, exposing his bare chest.

"Yes…I'd say it is rather warm…" Gunter answered hazily, removing his cape and draping it over a chair. He could feel Yuuri's gaze against his back. This slightly disturbed him, but he knew it was a good thing, since this had to be done…though Gunter was feeling more and more like a rapist. After all, he had drugged his king and intended to sleep with him…he was about ready to run out of the room, but an image of Gwendal submitting flashed through his consciousness…an image so delicious that it made this wrongness worth it.

"Hey, Gunter…" Yuuri said timidly, sounding a bit like he was afraid to ask whatever it was he was going to ask.

"Yes, Your Majesty?" Gunter answered, doing his best to sound open but not too horny.

"Call me Yuuri. And I have a question…" Yuuri continued.

"Yes, Yuuri?" Gunter asked gently.

"I was wondering…is it normal to have been thinking about sex…a lot?" Yuuri asked timidly. Gunter suppressed a laugh.

"No, Yuuri, it's perfectly normal for a teenage boy to think about sex" Gunter answered. He was slightly surprised by the question until he remembered that Yuuri was also affected by the aphrodisiac. He'd been preoccupied with his own…problems… and forgotten.

"But…the person I've been thinking about seems like it'd be a little…strange…to be thinking about him" Yuuri said, slightly stuttering.

"Who? Wolfram? Because that's-" Gunter pried curiously, only to be cut off.

"No. You." Yuuri said quickly, a violent blush staining his cheeks.

"Oh dear God" Gunter thought, stunned. "Please tell me this is just the aphrodisiac talking…and he must be the only person in the kingdom that doesn't know I'm with Gwendal…" but he knew this would be helpful, because he did have to bed the young king, even if that did make him practically like "Michael Jackson", a person from Earth that Yuuri had spoken of…

He mustered all his courage and imagined Gwendal, then said "That's quite a coincidence, because…I've been interested in you too…I've been trying to tell you that, but…perhaps I've come on so strong that the opposite effect had taken place?"

"I was sure it was too good to be true!" Yuuri exclaimed, eyes lighting up. Gunter inwardly groaned.

"So…you said you were curious about sex? Would it be too forward of me to…" Gunter started, feeling incredibly wrong but not letting on in the least. He kept the prize in sight.

"Are you serious? If you are…I don't want to wait" Yuuri answered, his blush returning faintly.

Gunter took this as a cue. "It's now or never" he uttered, inaudible to Yuuri. He then pulled the young king into a kiss.

--

The two collapsed, Yuuri completely exhausted, but Gunter still had plenty of energy. Gwendal was much more of a tiring lover, as he went harder and had much more stamina. Gunter muttered a short end-spell, causing the breeze to pick up and flow back into the bottle. He reached over, took the bottle and corked it, a slightly wicked smile creeping across his face.

"Yep, Gwendal, you're fucked" he said under his breath, making sure Yuuri didn't hear.

"I should go. We shouldn't be seen like this, since you are engaged to Wolfram. We could both get in serious trouble" Gunter told Yuuri apologetically. This was a lie. He knew he wouldn't get in any trouble. Yuuri and Wolfram were not actually married, and therefore nothing was wrong. Yuuri looked slightly disappointed, but nodded. Gunter dressed, inconspicuously pocketed the vial, and left Yuuri in the spare bedroom.

--

"Oh Gwendal" Gunter sang, almost floating into Gwendal's office he was so giddy.

"What do you want?" Gwendal growled. He missed his lover something fierce, but wasn't about to admit that. He wanted Gunter to beg his forgiveness and bend over his desk, but it didn't look like that was what was going on, so he was slightly irritated.

"I've won our bet. Starting tonight and lasting for a whole year, you're mine" Gunter said with a smirk. He licked his lips as Gwendal paled.

"Prove it." Gwendal hissed.

"Of course" Gunter answered. He smiled calmly and produced the bottle of air from his pocket. He uncorked it and the air began to swirl, creating a vague image that appeared to be two men-Gunter and Yuuri-going at it.

"Oh-oh! Gunter! Don't stop!" the wind image Yuuri cried. Gwendal nearly fainted.

"E-enough!" Gwendal stammered, hands trembling. He was not only in shock that Gunter went through with it, but also horribly jealous… and humiliated that he'd be on bottom for an entire year.
