Please note that I've never read the manga and so this story is based on the anime. That means Akito is a male. I got the plot bunny for this one from the scene where Akito starts beating Yuki in the little room.

Don't own them. I just like to take them out of the box and make them do nasty things together!

The Dark of His Heart

Akito allowed himself a self-satisfied smirk as he slid the door separating the tiny room from the rest of the house. The room's other occupant shuddered in terror at the sound of wood on wood. The quiet clack signified the start of their playtime.

Yuki sat huddled in the furthest part of the room; the one katty-corner from the door, with his knees drawn up to his chest. The backs of his white thighs gleamed in the darkness like pillars of mother of pearl. The sight made Akito's groin tighten and ache. He knew how this night would end and tonight sleep would not elude him as it did so many other nights.

"Yuki, Yuki, Yuki, do really enjoy our time together so much that you're just trying to find ways to extend it?" He stood over the frightened child slapping his whip gently against his thigh. He backhanded the boy with the fist the weapon was clenched in, knocking him onto his side. "Do you really think that I'm going to let you go so easily? Do you think that you can just walk out of here and not pay the price? You're going to have to earn the right to live with Shigure."

Yuki rolled onto his back, allowing his kimono to part and show more of that pale, flawless skin. Akito brought the whip down across the top of one alabaster thigh, leaving a red welt in the unsullied flesh.

"Strip and get on your hands and knees," he growled low in his throat. The soft whimperings from the teenager's windpipe caused Akito's cock to harden even more. He was almost tempted to forgo the beating and just get on to riding that fine little ass, but no; anticipation would make the rap-ah fucking all the sweeter. And besides, the arrogant little boy-cunt kneeling before him in doggie-style needed to be taken down a few notches.

He brought the whip down repeatedly across the slightly marred skin of Yuki's ass and thighs, faint bruises remained from the last time the family god needed to teach the rat a lesson in discipline. Those marks were joined by fingerprints in the boy's hips where Akito had grabbed him so tightly that he caused deep bruising to the area. Somehow the teenager managed to hide the evidence of their little games, which was all in all a good thing, as most authority figures would frown upon the uses that the older boy had for his sweet little cousin.

"Give me head, Bitch," he growled, whipping the sash that held his kimono closed off. He smiled as the young man turned and crawled, almost on his belly, over to where his tormentor stood. "If I didn't know better, I'd say you were a dog and not a rat. You're so good at showing your belly."

"Yes, Akito," Yuki whimpered, casting his eyes down to the tatami mats beneath their feet. He crawled over to the family god and kissed his way up from Akito's knees to the crease where his legs joined his torso.

Yuki licked his lips and then took the very tip of Akito's cock in his mouth. He swirled his tongue around the head, slipping it between the foreskin. Using just his mouth and lips, he pushed back the excess skin to get to the meaty part hidden inside. He encouraged Akito to sit on the floor; it wouldn't do to have the frail man who ruled his life fall and hurt himself. Not only would that get him into trouble with Hatori and Shigure, but it would give Akito another reason to demand his presence in their special room.

He took a deep breath through his nose, allowing the clean, musky scent that was Akito to flow into his olfactory senses. The fragrance of jasmine and patchouli wafted across Yuki's faculties arousing him, slightly. Akito's good-sized organ began filling his mouth and the older man roughly grabbed his hair and forced his cock deeper into Yuki's throat, nearly choking him. The rat struggled, trying to free himself from his tormentor.

"I don't think so, Yuki," Akito smirked. "Have you forgotten how this game is played? If you're going to be so absentminded then I think I will have to rescind my permission for you to live with Shi-chan and demand that you stay here with me. I mean it wouldn't be right if you forgot the man who took you in when you parents and older brother rejected you. Really, Yuki, how could you forget all that I've do for you?"

Yuki let Akito's manhood slip from his lips as he began to protest the loss of his freedom before he even had a chance to taste it. "I haven't forgotten how the game is played, Akito," he whispered, "please let me go to Shigure's. I promise that I won't lose sight of all you've done for me. Please," he begged, drawing closer to the god of the Zodiac.

"As long as you remember who you belong to, I don't see that there'll be a problem." Akito drew back his right hand and backhanded the fragile figure kneeling before him. "Now assume the position." The boy's begging had brought his cock to the full and upright position and he couldn't wait to bury it in the tight, slick passage that was his and his alone.

Yuki turned his back to Akito and placed his elbows flat on the floor. By the way things were shaping, tonight would probably leave him bruised and unable to walk. That meant that he would miss another day of school, but the academy that he attended at this time understood that his health tended to be a little brittle and it didn't take much for his asthma to act up and leave him homebound for a day or two. Unfortunately, most of the days that he actually missed were from him being sick, but from him being too sore to sit for long periods of time.

Akito reached into the pocket of his kimono and pulled out a tube of lube and a condom. Granted, Yuki hadn't slept with anyone else but him; the prophylactic was a necessity, it wouldn't do to end up with a bladder infection. Really, how would he explain it to Hatori? The man was way too sharp for Akito's peace of mind and he might just figure out what went on behind closed doors. If that happened, it would spell the end of his fun with the purple-eyed rat.

He squirted a generous handful into one hand and slathered his throbbing cock with the K-Y, shivering at the coolness of the lotion. He grabbed Yuki's hips and shoved his dick all the way in, not bothering to stretch or prepare the boy. The slick, wet heat that surrounded his cock was heaven and he drew back and thrust in again.

Yuki muffled his cries of pain in his forearms. He let enough sound out that Akito wouldn't feel let down, but not enough to draw Hatori's attention. The god rode him hard, hitting his sweet spot as often as he could. Yuki didn't hold any illusions that that gift was anything other than a way for his captor to control him. He moaned as the passion built in him. He twisted and turned, trying to reach the forgone conclusion on his own.

Akito brought the whip down on the rat's slender shoulders, mixing pain with the pleasure. He knew what was required to get the teenager off. The more something hurt Yuki, the harder he came. Akito rode him like the little whore he was. And his arousal became harder when he realized that along with the K-Y, streaks of blood marred the alabaster thighs before him. He grabbed slender hips harder and levered himself deeper into the willing orifice. He rammed the spongy knob deep inside the boy harder and harder, until he felt the muscles surrounding him tight and the whimpering became louder.

"What do you say, Bitch?" Akito ground out.

"Ah, please," Yuki panted, twisting around. "Please let me cum!"

"And who are you talking to, hm?"

"Master," the rat whispered.

Akito came to a complete and painful stop, holding the slim hips perfectly still. "What, Yuki? I couldn't hear you."

"Master!" he screamed, trying to finish what had been started.

"Good, little boy-cunt," he ground out, starting the wild rhythm again. He plowed deeper and deeper, his progress becoming difficult as Yuki shot his wad all over the mats. He continued on for another half hour before he finally came. He collapsed on top of Yuki's motionless body and lay there, trying to catch his breath.

When he could think and breathe again, he rolled Yuki over and redressed him. He then straightened his clothing and stumbled out of the room, leaving the delicate form battered and bruised on the rough mats.

When he was sure Akito had fallen asleep, Hatori let himself into the room, the one that he wasn't supposed to know about and looked at the abused form lying there, shivering in the chill of the night. He stepped out and gathered up a blanket he'd placed nearby and wrapped Yuki in it. He kneeled beside his younger cousin and swept the boy up in his arms. He carried outside and down the forest path to Shigure's.

The dog met him at the door to his home. "How bad is it, Ha-chan?"

"Bad enough that I didn't trust Akito not to rape him again," he said, sighing.

"He what?"

"You heard me. I never thought that things were as bad as they are. But tonight I decided to find out what goes on behind closed doors. And believe me you, if I knew how dangerous that bastard really was, I would have sent Yuki away before now."

"And what do you think Akito's going to do when he finds his favorite toy missing?"

"As of right now, Akito is probably starting to run a fever and he'll be out of commission until after the date for Yuki to move out." He clasped Shigure on the shoulder. "Don't worry about it, if I have my way, he will never find out what we've done." He thought about something and looked at the dog.

"Remember, idiot, children aren't houseplants, you just can't give them some water and leave them to their own devices. They needed to be watched carefully. And Yuki isn't some oversized toy for you to play your twisted games with." He glared at his cousin over the bundle in his arms.

"Hi-chan, you don't trust me?" he whined, giving the dragon his biggest puppy eyes.

"Worse, you dumb dog, I know you."

"Oh, right," Shigure answered, leading the way to the room that the teenager was going to be living in. He pulled back the covers and helped Hatori settle the boy in for the night.

"All right, I'm leaving. However, if you need me for anything, just call and I'll be here as soon as I can."

"No problem, Ha-chan. What should I do about the…ah…well you know."

"If he doesn't bring it up, don't you dare. He'll talk to one of us when he's good and ready. Now off to bed and I'll show myself out."

"Right. Good night then, Hatori." He followed the physician to the door. "Will you be by tomorrow?"

"Yes, I want to see how he's settling in. Good night, Shigure."

" 'Night."

Yuki woke to the sound of birds chirping in the trees. He was more than a little confused, the sun was coming in from the wrong direction and it was a little too noisy and bright for his prison. He looked around, the familiar walls and sounds of Shigure's home. He was safe. Never would Akito manage to get him alone and leave him battered and bruised again.

He stretched under the soft covers, wincing in pain. His activities last night left him more than sore. He slowly sat up, moving at a snail's pace to avoid causing himself more agony. He blushed when he realized that the only thing covering him was the soft sheets and blankets. His belly was still sticky from his cum spraying everywhere and his thighs were covered in K-Y jelly, blood and Akito's semen.

Even though he was thoroughly embarrassed, one thought raced through his mind…Free, he was free!
