Title: To love the Mazaku

Pairing: YusakexKoenma

Notes: Koenma has always had an attraction to Urameshi Yusuke...he made him a Spirit Detective to keep an eye on him. What happens when Yusuke sees teenage Koenma? How will the Three Worlds react if they realize Koenma finally has a weakness?


Chapter 3

Yusuke had been too focused on following Sensui that he hadn't heard Koenma's scream but Hiei and Kurama did. They paused briefly before following the detective in pursuit of their enemy.

Yusuke wasn't quite used to all if any of his new demonic powers; the heightened senses, the greater strength, hell the desire to mate and the changes to his body besides the nearly silent heartbeat. Being friends with two demons would help, if he survived this battle.

Yusuke was still riding his phoenix Puu as they seemed to float into the demonic realm.

Kurama was gilding using some plant's leaves to slow his decent while holding onto a rather uncomfortable looking Hiei Kuwabara.

Yusuke glanced back the way he came, 'sorry Koenma. I have to finish what I started. I'll come back. Wait for me. Please.' he thought as he returned his gaze to the crazy man in the Celestial Armor.

XoooooX

Koenma lost his authority after Sensui's apparent victory in the Human World when the Spirit World's Special Defense Forces were assembled. He refused to believe his Yusuke was a Monster like they claimed, he couldn't be. Yusuke had never been a bad kid, he just needed love and direction both of which Koenma was willing to give. He knew the young Spirit Detective better then anyone else, better then Kuwabara, Keiko or Botan and definitely better then Yusuke's drunk of a mother. Yusuke didn't have Sensui's black and white view of the world; Yusuke had a sense of honor and loyalty to his friends that kept him true.

Koenma was pacing outside Demon's Door Cave. He needed to feel close to him. Where was Yusuke? Was he okay? Koenma wanted his lover back, to have Yusuke trapped behind the Kaka barrier in Demon world that was being repaired by Spirit World's Special forces. IF there was a way back surely Yusuke would find it…they hadn't had time to be together since just before they found out about Sensui. That was too long…

XoooooX

Yusuke kicked a tree, the joy of beating Sensui was taken from him. Someone had taken control of his body increasing his power and used it to destroy Sensei. His greatest enemy, a rival and he didn't even know if he could defeat him because he didn't do it! Damn it all the hell. Wait, he was in Hell. Much nicer looking place then once was led to believe. He wouldn't mind a vacation in hell but living there…no way.

Angry and confused Yusuke lets Kurama and Hiei show him how to get back to human world. Sensei is beaten the Human World protected against a horde of hungry demons bent on death and destruction

XoooooX

Koenma had kept his true relationship with Yusuke between them but when Yusuke emerged from Demon's Door Cave he pulled the young Spirit Detective into his arms, "You're back. You're safe." he didn't care that Yusuke looked different; he was the long-haired/tattoo wonder. Not many can beat death twice…

Yusuke clutched Koenma's robes in his hand, "Sensei's dead…but I didn't do it. I didn't beat him" he was angry.

"Hush now. Let's go back to your place." Honestly, he'd never have sex with a demon before. He wanted to see just what was different about Yusuke now that he was the Avatar of the Mazaku.

Keiko blushed, she hadn't expected that.

Hiei smirked, nudging Yusuke, "I see, so there is someone that the Great Yusuke Urameshi bows to. You'll find you heartbeat isn't the only thing that changed."

Kurama pressed a handful of nuts into Yusuke's hand, "Eat one before you have sex. Trust me."

"Yeah yeah." Yusuke said pocketing the nuts.

Kuwabara stammered, "Urameshi! You're cheating on Keiko with Koenma? How could you!"

Yusuke growled, "I'm cheating on no one. I was never seeing Keiko. Everyone just assumed we were together. I've only been with Koenma."

Botan twittered, going all kitty, "So Yusuke, tell me, what's Koenma like in bed?"

Yusuke turned pink growling, "None of your business. That's for me to know and you to never find out."

Koenma glared, "Why don't you focus on your ferrying duties and forget you saw us."

"Aren't you coming back to spirit world?"

Koenma shook his head, "I defied my father for the person I loved. That is a choice that won't be easily forgiven. Best to hide out until he calms down otherwise he will forget I'm his heir. This time I don't think he'd be content with a spanking."

Yusuke was a zillion times stronger then Koenma and could dominate the junior ruler of Spirit World. But he was so attracted to Koenma and his need for the man made him desire Koenma to make love to him rather then the other way around. His temper and foul mouth truly was a protection mechanism so people wouldn't get so close. Koenma forced his way into his life and gave him a purpose. He snorted, "King Enma is frightened of me? Good. Tell him, he lays one hand on Koenma I'll give him a hell of a show. I may start to think I've been on the wrong side all along. No one hurts or threatens Koenma."

Kuwabara snorted, "Don't know what you want a toddler when you could have Keiko."

"I'm not a toddler! I'm nearly seven centuries old." Koenma stamped.

"Oh really? Because you don't look a day older then sixteen." Keiko teased, "Yusuke, you're dating an old man?"

"No, I'm sleeping with the former Prince of Spirit World not that it is any of your business. Come on. Mom wasn't home but…I want you to stay with me." He was sure that his mother would be so drunk she wouldn't notice that he was having sex. Or they could just manipulate their spirit energy to mask the sounds they made. Besides, his demon blood wanted to mate and his human soul wanted only Koenma.

XoooooX

Yusuke checked for his mother and found their apartment empty. It was legal for them to have sex here; age of consent in Japan was thirteen for females but there was no set age for males. Besides, As long as Koenma looked sixteen it was fine, his lover just couldn't look older or younger then that. Good thing he never tried to kiss toddler Koenma. He undressed walking backwards to the bathroom and putting his filthy clothes in the laundry basket. "Come on Koenma. You know that royal ass of yours needs to clean up. Fighting is dirty business."

Koenma licked his lips, "You look hot with all that hair and those tattoos."

Yusuke turned the shower on and climbed in, "Come on." he started to wash Demon's Door and Demon World off him. His soapy hands roaming over his body. "My body saved the world. Don't I get a bit of a reward for semi-succeeding in my mission?"

Koenma undressed, joining the teen in the shower, pressing his body flush against Yusuke's back and ass. He rest his cheek on Yusuke's shoulder blade, "I was worried you wouldn't come back after I lost you. I didn't have the power to bring you back too." he could barely hear the beat of his lover's heart.

"I came back for you and because I hadn't finished my mission." he hadn't wanted to die and make them all upset again. He was starting to feel more alive with Koenma pressed against him.

Koenma reached for the soap and started to wash the boy, "I'm glad you came back. I would be miserable and lonely without you." being a demon, Yusuke could live far longer if he didn't get himself killed. He could feel the strength radiating off his lover, he was so strong right now. He felt awed that Yusuke would give up control and let him, a weaker person love him.

Yusuke closed his eyes and just enjoyed his lover's touch, he needed to feel Koenma pound into him, "Take me. Please. Fuck me." forget the nut that Kurama said he had to eat.

Koenma turned Yusuke around, lifting the teen and entering him with one thrust.

Yusuke wrapped himself about the prince of spirit world groaning. The pain of being penetrated without being stretched gently first felt so good. The burn…

Koenma pounded into the boy, one hand on the teen's back and the other wrapped about Yusuke's member pumping it.

It didn't take them long to come…

Yusuke's demon sex drive wasn't satisfied in the least.

After drying off and sensing the apartment was empty they retired to Yusuke's bed where they went on for another four rounds before collapsing temporarily sated.

XoooooX

Outside perched in a tree were Kurama and Hiei.

"Damn, I didn't think toddler king had it in him to satisfy a demon." Hiei snorted.

Kurama laughed, "One wouldn't expect you to be able to be satisfied by my endurance."

Hiei glared, "No my fault. Haven't reached puberty yet. Seriously, not important. I can still enjoy myself."

"You are maturing faster then a normal ice apparition."

"I'm half fire demon so of course I'd mature faster then Yukina. She is just an ice apparition."

"When you reach puberty I'll let you see if you can satisfy Yoko." Kurama teased, he was older then Hiei if you compare physical maturity rather then age even in his human form. If the bond between them wasn't so strong they wouldn't be able to be physically intimate."

"What was it you gave Yusuke?" Hiei asked absently massaging Kurama's shoulders.

"The shinoma nut, it's a nut from demon world. Amoung it's healing properties, when baked dipped in chocolate it is also an aphrodisiac but if raw and dried it's a contraceptive."

"Why does Yusuke need a contraceptive?"

"Simple, we watched his demon power awaken. He is technically only half demon but can't you smell that he is in heat? His first demonic heat and his power was pushed very far, his demonic energy is entwined with his spirit energy. If he hadn't been awakened as fast as he was I wouldn't have expected him to go into heat for another two hundred and eighty-five years. He is fifteen in human years and he has only been a demon a couple of hours. Not only is he in heat; Yusuke is sexually aroused and fertile."

Hiei looked ill, "He didn't eat the nut…"

"He has five hours to do so. His body has to register it can conceive."

"He was human a few hours ago."

"His body changed and he gained demon attributes including the ability to conceive. Once he regains control we're going to have to give him demon lessons. Granted we are of a different type but he still needs to learn to control himself."

"What happens if he doesn't take the nut in time?"

Kurama leered at him, "Same this that will happen to me when you reach puberty in a few months. I'll end up pregnant."

Hiei coughed, "I'm not sure I'm ready for that. To see either you or Yusuke pregnant would be shocking." he still was surprised that Kurama let him top…it was shocking that he was capable of sex considering that he was young for it. He knew few demons besides Kurama would accept him. Yoko Kurama pregnant by a 4'10 fire demon/ice apparition would be a sight to see.

Kurama glanced at the sleeping prince and the newly awakened demon, he hoped for Yusuke's sake he remembered the nut. The human world wasn't ready for a fifteen year old boy to become pregnant. He also worried that a half Mazaku infant would crave humans and he didn't think Yusuke could bring himself to eat his own kind.


Sorry, I got blocked on Mazaku- or was it distracted by Harry Potter? Either way I'm back now...

Should Yusuke remember the nut?

Yusuke getting demon lessons from Kurama and Hiei will be funny. Hiei you might suspect of voyeurism but Kurama?

Akira shock!

Wonder why Koenma hasn't figured it out? Oh right, because Yoko Kurama is the one that plans about six steps ahead and Shuuichi is a genius. Hiei gets distracted easily because of his anger but doesn't lack intelligence.
