This story has been updated to correct a number of errors and to change the format a little, no changes have been made to the plot. When I re read this after six years of posting it, I was just appalled by the number of mistakes I made the first time around. As you may know, english is not my native language and I don't have a Beta, so there might still be a couple mistakes, but definitely fewer than before... There were just so, so many...

I will probably correct all my old stories if I have the time, including the sequels to this one.

Anyhow, still rated M, still BL, still don't own KKM or any of its characters. Please, do enjoy ;)

"No! Anissina!" the screams could be heard throughout the castle, just before the sound of an explosion made its way to the ears of five people, who were calmly drinking tea on the courtyard.

The earth slightly shook, making the table jump, which would have been a problem if they hadn't lifted their respective cups, after hearing Gwendal's panicking voice, almost as a conditioned reflex, caused by living with Anissina all those years.

"Poor Gwendal" Yuuri said leaving his cup back on the table and taking a cookie.

"Oh you don't have to pity him Heika, that is how those two show their love for each other" answered Cheri giggling and directing a sparkling glance in the direction of the smoke, which would soon fill the east wing of the castle.

"If you say so..." Yuuri remembered a saying that went something along the lines of love hurts or who loves you will hurt you, and thought this family maybe took it a bit too seriously. Little did Yuuri know then, but soon he would be learning that fact to be completely true, with his own body as proof.

Wolfram was sitting in front of Yuuri and had received a wink and a chuckle from his mother when the young Maou was too lost on his thoughts to notice. Wolfram knew exactly why his mother had thought this particular subject might concern him. He had his own way of showing Yuuri how much he cared about him, not that the wimp noticed anyway.

Wolfram was a fire wielder and he was, even if he hated being part of the stereotype, a passionate, possessive and maybe just a little aggressive person, maybe not so little... The thing was, it had nearly been three years since he and Yuuri had gotten engaged and there had been no progress on their relationship. Now, it wasn't that he wanted to marry right away, he was still young and Yuuri was definitely too young, it took some time for him to understand the age difference between them in terms of balancing Shin Makoku and Earth's time on his head, but now that he did, he understood that Yuuri wouldn't want to marry yet. No, marriage was not the problem, marriage could wait, but Wolfram's hormones, well, no so much.

Wolfram was proud of himself for having been a gentleman his entire life, no matter who his partner was, he had never crossed certain lines; he had fun of course and had his share of puppy love. He courted and was courted more times than he could remember, he had kissed and even gone a little further with some of them, but, as the gentleman he was he never got too far, his honor was also on the line, and there was no force in the world that would make him stain himself, or so he thought.

The issue here was that said honorable gentleman never shared a bed with any of his former partners, and even more, he had never been rejected. This new problem was something completely unprecedented for Wolfram, he had never, not once, been rejected like this. Both men and women would kneel before him, asking for his attention. In retrospect, that was probably one of the reasons he never fell in love before Yuuri. That's right, he loved Yuuri with all his heart, he loved the wimpy, clumsy, naive, too kind excuse for a king he had as a fiance. The purity of Yuuri's heart had captivated him. They were just so different in every way. He even was a water wielder.

"Heika! Heika!" Günter was running with a bunch of books in his arms "You are late for your lessons Heika! Why do you hate me so? Are my lessons not worthy of your time?" he cried as he reached the table.

"I'm coming Günter. Greta are you coming with me?" Yuuri asked, taking the hand of the little girl who nodded in response. Wolfram also excused himself and the four of them began walking to the castle's first floor library, but Günter corrected them and said that day's lessons would be held on one of the libraries of the second floor.

Wolfram wondered what were they going to study in there, it was an old and small room he had been in only a few times, hiding mostly, so he had never looked at the books, but now that he did, he noticed most of them had strange covers and even stranger titles

"Heika, today we will be studying the eleventh Maou of this, our nation, his majesty Elias, the Wise, he devoted his life to the study of majutsu amongst other things. Now, we'll start..." At that point Wolfram turned off his ears, it wasn't just the boring subject, but Günter's voice that made it impossible to listen.

He began examining the room, walking between the bookshelves, running his fingers through the books, looking for something interesting to read. Suddenly a quite exuberant book caught his eye. It was really old and was covered with dust. By looking at it Wolfram guessed it may have had about a thousand pages, he pulled it out, blew away the dust and inspected it further.

The cover was of a bright purple velvet, Wolfram could only imagine how flashy the thing must have been, back on its day. It had some sort of weird symbol on the cover, like a four pointed star, with something in the middle that could no longer be distinguished. The title was a bit blurry so he walked to a window to look under the light. Element wielders and sex, Wolfram read it over and over again thinking he had somehow misinterpreted the meaning of the letters, but the title didn't change. He felt a small flush forming on his cheeks, holding this kind of book next to his daughter and fiance.

Curiosity ended up getting the best of him and he walked away, to another table, on the corner of the room and started rapidly flipping the pages, still not all that convinced about reading this book, considering all the other people who were present, just a couple of tables away. But then, like it was destiny's work, a page got stuck to his finger and, looking at it closer, Wolfram saw a title he couldn't ignore at the top of the page The sexual personality of a water wielder. Wolfram looked up once more to make sure Yuuri and Greta were either paying attention to Günter or dozing off, any of the above was okay by him. He continued reading trying to look indifferent.

Water wielders are often very kind and outgoing people, who would not hesitate to help others, or make new acquaintances; however, in terms of their love lives, they tend to be more reserved.

No surprise there

It is not abnormal for them to run away from reality, not realizing their own feelings or sexual needs until they are confronted with them. This being the case, it is not recommendable for those who are sharing their lives with the water wielders, to force them into confronting them, but rather make it impossible not to do it themselves.

Okay...? Care to explain how?

Once they have come to terms with their feelings, the hidden side of their personality comes to life. The water wielder knows the power of carnal instinct and consuming desire.

Wolfram couldn't kept himself from imagining Yuuri consumed by desire and succumbing to his carnal instincts. He had to take a deep breath before continuing. He noticed that, at the end of the page, there was another title, Water wielders's sexual compatibility, and second on the list was fire.

The misconception of fire wielders and water wielders being completely incompatible has been spread through generations, and in many points it is, in deed, correct. Nonetheless, sex it is not one of them. The fire wielder will desire the contact and touch as much as the water wielder will desire to provide it . Rather than simply putting out the fire of the owner of this element, the water wielders will consume that fire by making their partners ecstasy, for their passion can be as strong as the stormy tides of the ocean.

Wolfram swallowed heavily and looked at Yuuri, who was apparently very interested on Günter's lesson, which seemed very weird to Wolfram, but he had no time to waste on finding out the reason for his fiance's sudden interest in the history of Shin Makoku. The damned book along with Wolfram's very vivid imagination, and more than two years of piled up sexual frustration, had had an undesired effect on his body. After a few panicking seconds he decided that taking a bath would probably be the best choice to calm himself down. He stood up as quietly as he could and left the room holding his breath and without looking back. He sighed in relief when he closed the door behind him. But now he had another problem, getting to the baths without anyone noticing his problem.

He thought for a second and got to the conclusion of using the Maou's personal bath, it was closer and no one would bother him there. Once that was decided, Wolfram started walking, way too stiffly, even for him, drawing the attention of one of the maids who ran pass him, of course she never imagined the real reason for this odd behavior and automatically related it to him being angry at the Maou for some reason. It didn't make much sense, but normally any change in Wolfram's behavior was due to him being upset, and Yuuri always had something to do with it so the logic wasn't so bad. In fact, from Wolfram's point of view, this was Yuuri's fault.

When Wolfram finally got to the bath, took off his clothes and entered the water something he was not expecting happened. He was just starting to relax when he saw the slender yet quite muscular figure of his fiance walking in with nothing on except for a small towel.

"Hey Wolf, so you were here. Greta and I were wondering where you had gone off to so quickly. I spilled some ink all over myself so I got a free get-out-of-the-boring-class ticket" Yuuri said grinning.

Wolfram's heart gave a jump as the other boy entered the water right next to him. He was never so thankful of having picked up the custom of entering the bath with a towel around his waist from Yuuri. He prayed to the Great One, and anyone or anything that could hear him really, for Yuuri not to notice. But having Yuuri's body naked next to him was not helping at all, he could feel his problem getting worse, the images of a passion consumed Yuuri fucking him senseless were mixing up with the real thing in front of him, making his breathing grow heavier, and his body temperature to raise.

Yuuri was enjoying the warm water when something caught his attention. There was no real reason, more like an instinct, but something told him he had to look down, and there it was, under Wolfram's small towel, a not so well hidden erection. He was shocked, but he didn't showed it on his face, instead he looked up into Wolfram's eyes, that looked back at him, realizing he had been discovered.

Wolfram's cheeks flushed with embarrassment and he looked down, one of his golden ringlets falling in front of his eyes as he bit his lower lip. Yuuri looked closely onto those emerald eyes and found something new in them, some kind of glow.

It was lust, he was aroused, Wolfram von Bielefeld was aroused. Yuuri took another look at the picture in front of him, that wet golden hair falling randomly in front of a set of emerald green eyes, and sticking to the back Wolfram's neck. The flush on his cheeks contrasted with his pale skin as he bit on his cherry colored lower lip. His entire body was exposed, Yuuri had seen Wolfram's body before, but he never really looked, not like he was now. He was so little and at the same time so firm, a trained and fit body with soft curves and a pronounced waist. It was almost heavenly.

Wolfram felt Yuuri's eyes scanning him from head to toe. He wanted to disappear, he wanted the ground to open and swallow him whole, but still his arousal would not go away. Something about having Yuuri looking at his body like that, made him desire his touch more than he ever had before. He had to get out of there soon, or he would do something he would regret later. He put his hands at the edge of the bath to help himself up and then he felt something pulling him back down, Yuuri was grabbing his arm and looking at him in a way he had never seen before. His jet black eyes were staring at him with determination, his mouth was slightly opened and soft panting came out of it. Wolfram was reaching his limit.

Yuuri didn't think, he just acted, something in his body told him he couldn't let Wolfram go. For some reason his thoughts could not pass through to him, he felt he needed to touch Wolfram and nothing else mattered in the world. He still had his hand holding Wolfram's wrist, so without breaking the contact, he started to go up on his arm, touching it softly with the tip of his fingers. He could feel Wolfram reacting to his touch, shivering and tensing up, biting his lower lip even harder. When he got to the shoulder he continued his exploration now down on Wolfram's chest, passing slowly through his collarbone and then lower, barely touching a nipple on his way down.

Wolfram let out a soft moan at that contact, Yuuri felt something taking control over him, he was the one causing this arousal on Wolfram, he had madewolfram moan, his head was spinning, he felt the last of his common sense slipping away when Wolfram looked at him panting, asking for more with his eyes.

He grabbed both of Wolfram's arms and pulled him closer, their foreheads touching, their panting breaths mixing, their hearts pounding. Wolfram was the one to take the lead this time, looking up to join their lips together, when was it that the wimp became that much taller than him he didn't knew.

They shared a short chaste kiss and broke away, losing themselves into eachother's eyes once more. Yuuri kissed Wolfram again but this time the kiss slowly became more demanding, more heated. Soon their tongues were playing, pushing, fighting to be the one to enter the other. Yuuri won and was enjoying exploring the the inside of Wolfram's mouth, when he felt Wolfram sucking on his tongue. He let out a soft groan of pleasure and broke away from the kiss. He moved on to his lover's neck, first kissing it softly and then running his tongue through it, making Wolfram moan louder and louder once he got to his ear lobe and started sucking on it, burying his face on those beautiful blond locks and holding him tightly in his arms.

Wolfram had become very aware of every inch on his body that was now in contact with Yuuri's. He felt their sweat mixing with the water and the steam and thought he was going to faint from the pleasure as their erections rubbed against each other, only separated by the thin towels. He let out a loud moan making Yuuri groan on his ear. Yuuri didn't know what to do to make them be even closer together, he wanted to fuse them together, he wanted to hear Wolfram moaning uncontrollably and screaming his name.

He grabbed Wolfram by the waist and lifted him, making him sit on the edge of the bath, getting rid of the towel on the way. Wolfram's erection was completely exposed and he felt a little embarrassed, a small blush forming on his cheeks. He had to put one hand on the floor to hold himself together, and to hold to to his sanity, when Yuuri began kissing the inside of his thighs. Then Yuuri held his erection in one hand and gave an experimental lick, Wolfram's entire body quivered and he had to bring a hand to his mouth to stop himself from literally screaming in pleasure, he had never felt this way before, he felt lightheaded and hot and couldn't even try to think coherently.

After a few more licks Yuuri took Wolfram's entire member into his mouth and began gaining a slow rhythm, Wolfram was biting his hand so hard it drew blood, he couldn't take it any more, the whole thing was too much for him, he couldn't believe Yuuri was doing this, his heart was about to jump out of him. Yuuri accidentally touched Wolfram's tip with his teeth, barely a touch but enough to send Wolfram over the edge.

"Yuuri... don't... I... I can't..." Yuuri gave a final lick before pushing away just in time, as Wolfram came all over his own chest and almost fell to the floor, resting his weight on his elbows, panting heavily.

Yuuri sat on the edge of the bath too and, for the first time, thanked Murata for forcing him to read those weird yaoi manga. He grabbed Wolfram by the waist again, making him sit on his lap, facing him. He started to kiss his abdomen and neck to finally give him a passionate kiss on the lips.

Wolfram's erection was coming to life again quite quickly, as he enjoyed his lover's attention. Yuuri then broke away and lifted Wolfram in a way that he was resting his weight on his knees and shins, leaving the way open for Yuuri. He took the cum still on Wolfram's stomach on his fingers and looked at him asking for permission.

At that moment, even if it made absolutely no sense, all that Wolfram wanted was to feel Yuuri inside of him so he nodded in agreement.

Yuuri carefully put the first finger in and felt Wolfram's body tensing in pain, he kissed him softly, hoping to distract him from the pain, and when he felt his lover relaxing he went for the second and finally the third finger and started to move them around.

Wolfram was in pain, there was no doubt about it, but at the same time he could feel his body heating up, and somehow he felt dizzy. Suddenly Yuuri stroke a point inside of him that made him shake and let out a moan. "There..." was all he could bring himself to whisper in Yuuri's ear. Yuuri had no idea where he had touched, but he tried to move his finger in the same way he had before, and by a stroke of luck he found it, making Wolfram grab his shoulders and bury his nails on them, moaning and panting.

When Yuuri couldn't stand it any more he removed his fingers, Wolfram made some disappointment whimpers, making Yuuri chuckle. He lifted Wolfram up and positioned himself on his entrance, looking at him asking for permission one last time, Wolfram responded by kissing him softly on the lips.

"I think this is gonna hurt a little, so bear with it for a moment, okay?" Wolfram nodded and squeezed Yuuri's shoulders as he slowly entered him. Wolfram couldn't help but to scream in pain, he felt he was going to break in half. Yuuri held him by the waist helping him to stay still while his body shivered.

Once Yuuri felt Wolfram relaxing into the intrusion, he slowly pushed him down penetrating him completely, Wolfram's body tensed and Yuuri had to force himself to stay still. He was going crazy, Wolfram's inside was so warm, so tight, he was inside of the Wolfram von Bielefeld, making him pant, and moan, and sweat. He had to take a couple of deep breaths to stop himself from climaxing instantly.

After a minute Wolfram's body started to get used to the new sensation and the muscles of his legs relaxed, letting himself fall completely into Yuuri's lap making the penetration even deeper. Making use of all of the self control Yuuri might possibly had had, he began lifting Wolfram by his waist, thrusting into him in a slow pace.

The pain Wolfram felt started to mix with pleasure, once his sweet spot was found once again by his lover. Their rhythm began to accelerate as their passion grew larger. Wolfram's eyes were covered by desire, as he started to move his hips on his own, he wanted to feel Yuuri deeper, faster, rougher. The entire world belonged to them, becoming one, losing themselves on the sensation of their sweaty skin slipping against each other's.

The bathroom walls echoed with the panting, groaning and moaning of the couple giving in to ecstasy. Wolfram began biting Yuuri's neck and collarbone, leaving bleeding love bites behind. As he reached his release he buried his nails on Yuuri's back scratching all the way down to his lower back coming for the second time, while shouting Yuuri's name.

Yuuri never thought pain could feel so good, blood falling down his chest and back. The image of a blond lock, sticking to Wolfram's slightly swalloed lips, while he licked his blood out of them, made Yuuri groan. Wolfram's insides tightened while he released, Yuuri just needed a little more to be sent over the edge and the sound of his lover screaming out his name was it. With a last thrust, he came inside of Wolfram's body and laid back on the floor, his lover collapsing on top of him.

It took them a moment to recover their breath. Wolfram then moved away and let himself fall by Yuuri's side, who then held him, making him rest his head on his chest. Coherent thinking was starting to come back to Yuuri's head, but he could see things in a different way now. Though he wasn't quite ready to admit it aloud just yet. There are some words that should not be uttered lightly, and he wasn't going to, not that day, but maybe soon.

He smiled and held Wolfram closer, running his fingers through those beautiful golden locks, hoping Wolfram would get the message somehow, without having to speak. Like reading his mind, Wolfram smiled back and caressed Yuuri's chest, passing his fingers through the ruby colored love bites, fascinated by having been able to mark Yuuri's body like that. They remained in silence until the afterglow faded out of Wolfram, making him remember something

"They must have missed us at lunch".

That night Yuuri undressed in front of the full body mirror. He took off the jacket that had been buttoned all the way up the entire day and the rest of his clothes, and put on only the pajama bottoms, to take a closer look at his body. His shoulders and part of his neck were covered in love bites. He turned around to see the red trails Wolfram's nails had left on his back. He looked back at the bed where Wolfram was waiting for him, with a somewhat transparent blue nightgown and a book on his hands.

Noticing he was being watched Wolfram put the book on the nightstand, pulled away the covers and and gave Yuuri an inviting grin. Yuuri walked to the bed smiling, thinking maybe it wasn't that bad that love hurt, if it was going to hurt like that.
