Author's note: I don't normally write Author's notes, but I just wanted to say thank you to the overwhelming support I received for this fic. By popular demand I have decided to lengthen it into a full story. I truly hope you all enjoy this as much as you did the first chapter.

If you had told Al, the prince of Darkness, the ruler of all evil, that he would have an angel freely roaming the hallways of his palace before Arthur, he'd have thrown you into the pit of fire and laughed at how moronic that very idea was. It was known to all that Al despised angels. He hated every thing about them. It had caught everyone by surprise when he'd announced that the English angel was his mate.

The lower demons in the palace quickly learned not to question their king's odd choice of lover. Al was fiercely protective over the angel, quick to disembowel anyone he heard bad mouthing him or giving Arthur trouble. They all learned quickly that Arthur's word was just as powerful as Al's and none dared to defy this odd mate of their king.

It was unknown to all but Al what the angel's true purpose was. He thought of his brilliant plan on his own, had hatched it out of the deep recesses of his demented mind and so far, everything was going swimmingly. He had not expected Arthur to fall in love with him. He had not expected the sex and the kisses but it wasn't unpleasant for him.

He found himself consorting with Arthur more and more about how to rule his kingdom and how to punish and reward his subjects that deserved it. He found that Arthur was wise and insightful, and even though he was an angel, he was not against Al's often harsh punishments. It was as if Arthur was almost meant to be his mate.

Al couldn't help but laugh at that thought. It was absurd. Arthur was just a perfect tool in his plot to take control of Heaven. Arthur had proven to be easy to manipulate, once he discovered how the angel's mind worked. He gave Arthur what he wanted: love, affection, trust and power. There were times when even he was surprised by Arthur's desire for power.

The angel was strong, he could see that much. He could feel it whenever he was around him. It wasn't hard to train him to be a soldier. Arthur had accepted the training without question, once he had agreed to Al's request, and he excelled with flying colors. Al was almost proud of him as he watched him during drills.

Arthur did not receive any special training. Al thought it fitting to put him into the same training regime as his army, and his decision had proven to be right. The added stress of being surrounded by demons wanting to destroy him had made Arthur even stronger than he could imagine.

He continued to feign kindness and love every evening as Arthur came limping back to their chambers after his training. He'd rubbed his sore shoulders and kissed his bruises as he listened to Arthur speak about whatever he was thinking. He fell into a comfortable routine with Arthur.

There was a feast in Arthur's honor the night before he was to depart on his mission, and Al had gone out of his way to make it an extravagant affair. The party lasted long into the night, and only ended when Arthur ended up straddling his lap, his lips on his neck and his hands in his hair. The guests dissipated quickly as Al carried his mate back to their chambers, and he still smiled as he thought about that night. That had been the best sex he'd ever had.

The morning after, however, had left a bitter taste in the devil's mouth. He'd awakened to Arthur kissing his forehead, and he smiled up at him. "Good morning." Arthur's eyes sparked in the dim red glow of the morning fires burning outside the window, and the way the light flickered on his skin made him seem almost ethereal.

He didn't expect Arthur to climb atop his still nude body, didn't expect him to toss the blankets to the floor and didn't expect the soft, gentle kisses that Arthur placed on his lips. It was strange to him. Having Arthur on top of him was outside the norm, but he supposed, since he was likely to die on this mission that he would allow him to continue.

Arthur ran his fingers through Al's hair, and kissed him in a way Al never had been kissed before. It wasn't rough or needy or full of lust. It was slow, soft, gentle kisses. Al didn't know how to react to them, so he settled for resting his hands on the angel's hips, letting Arthur lead for now.

It almost startled him, when he felt Arthur's tongue on his lower lip. He'd grown used to the soft pecks but he didn't deny the angel entrance. As Arthur kissed him, he couldn't help his hand from slipping up the angel's bare back, feeling the smooth skin beneath his fingers for the first time. He'd touched Arthur many times before, but this was the first time he really felt him. The angel's skin was smooth, soft and warm.

Arthur led him in the kiss, entwined their tongues and gently explored the demon's mouth. Al didn't understand this. He didn't understand why Arthur would want to kiss him like this, there was no... passion behind it. It was strange... He didn't know why his body was reacting so strongly to just kissing like this.

"I love you..." the words were whispered against Al's lips so softly he almost didn't hear them, and it made his cheeks flush. He knew Arthur loved him. He'd said so hundreds of times before, but this time felt different. It made his heart race.

Arthur kissed him for a few more moments, and then sat up, looked down from his perch atop Al's waist, almost as if he were searching for something. Al, for the life of him, didn't know what that could possibly be. "I love you... " Arthur repeatedly, loudly this time and Al licked his lips and smiled.

That seemed to be an appropriate answer, and Arthur reached behind him, and revealed a small bottle with a smirk. Al knew that bottle. Lube... they hardly ever used lube. Al was usually too full of lust to care if Arthur hurt or not, and that thought sent a quick pang of guilt through his chest as he watched Arthur uncork the bottle and pour a liberal amount of the thick liquid onto his slender fingers.

Arthur's hand slid behind him, and his cheeks flushed a deep red. "Al... watch me..." As if Al could look away at this point. Arthur had never done anything like this before, and to say that the angel was intoxicating was an understatement. He felt his cock throb as Arthur bit down on his lower lip, and Al knew just what the angel was doing. He was fingering himself. And holy Hell, that was the sexiest thing he'd ever seen.

The demon's eyes traveled Arthur's body, really looked at him for the first time. He certainly was attractive, and the way that his skin moved over his muscles and bones was certainly alluring. His eyes darted back up to Arthur's face, and his cheeks darkened even more when he took in the look of desire, pleasure, lust that was apparent on the angel's face.

Al's cock was throbbing with desire, but it was almost as if the angel had cast a spell on him. He was trapped, his body refusing to move to take what he wanted as Arthur's body writhed atop him, and then, without him even noticing, he felt a familiar heat against the head of his prick.

His eyes closed in concentration, and he groaned softly. Arthur stopped, and Al groaned again, this time impatiently. "Open your eyes... Don't look away from me..." It was a command. A gentle command, but a command nonetheless. Al's eyes shot open, and rested on the familiar emerald green ones of his mate, and Arthur began to sink onto his cock once more.

Arthur wanted Al to watch him. It was odd to Al, but not something he couldn't do. Even as Arthur's eyes fluttered shut as he sank down on his cock, he kept his open and on the angel. It felt like ages that Arthur sat upon his dick, unmoving, his face twisted in discomfort and concentration and finally, as Arthur's face relaxed, he felt him begin to move.

It was agonizingly slow for Al but he couldn't take his eyes away from the angel riding him. Arthur's face was the perfect mirror for what the angel was feeling, scrunching when he was uncomfortable, his mouth falling open when it was pleasurable.

"Touch me..." Another command that Al was powerless to disobey. His hand went immediately to Arthur's cock, and grasped it firmly only to be gently shifted away. "Not there... Touch me here..." Arthur led Al's hand up to his chest, rested it right over his fluttering heart. Al could feel it under his palm, and it suddenly hit him. Arthur was making love to him.

That sudden realization hit him hard, and suddenly the whole experience was more pleasurable to him. Slowly, trying not to disturb Arthur, he began to roll his hips up and into the angel. The moan that resounded through the room went straight to his cock, and it took all he had to not flip them over and fuck the angel into the mattress. But for some reason, he didn't want to ruin this for the angel, not when he was making such delicious mewls and pleasured faces.

Arthur's brows furrowed, his body beginning to sweat and tremble as he rode the demon, and Al couldn't look away. His hands were moving of their own accord now, sliding up the angel's side, caressing a cheek, resting on his thigh. He felt like he had to touch every inch of Arthur as the angel pleasured himself with his dick.

Al groaned again, and hesitantly spoke. "Hey... Let me sit up a bit..." Arthur nodded, and allowed them to be separated so Al could scoot back on the bed, and rest against the headboard, his torso now erect. He didn't know when they reconnected, but he did remember Arthur's lips against his own, almost frantically kissing him, in a confusing contrast to the slow movements of his hips.

Al liked this position better. He wrapped his strong arms around the angel, helped him ride his cock with sure and careful movements, keeping the pace as Arthur wanted it. He knew that Arthur's sweet spot was being hit, he could tell by the way the angel's head had fallen to rest on his shoulder, and the way his muscles clenched when he lowered himself down.

Al's head was swimming. He didn't know what to pay attention to; the hands gripping his hair, the kisses to his neck, the weeping cock pressed between their bellies or the tight heat around his cock. It was all too much for him to focus on, so he busied himself with soft, gentle nips to the angel's exposed ear.

Arthur's movements were getting erratic, and his breath was laced with moans and whines and Al could tell just how close the angel was from this. Arthur whimpered softly, whispered out another confession of love into Al's ear and he lost it, fell over the edge and spilled himself inside the angel with a husky groan.

Arthur didn't last much longer after feeling his mate's seed fill him, and his breath caught in his chest as Al felt the warm liquid spray between them.

He held Arthur close, not quite sure what else he was supposed to do after what they just did, and suddenly felt that wave of guilt hit him again, stronger than ever. It wasn't until Arthur pulled back and climbed off him, slowly did he allow himself to speak. "Arthur?" The angel didn't turn around, didn't respond and Al instantly knew that he was crying as he dressed himself.

Fuck... He hadn't meant to make him cry, and a part of him wondered why he even cared, but Arthur was dressed and gone before he could say anything else about it. The devil sighed, stood and followed suit, cleaned himself up and dressed quickly to see Arthur off, as was expected of him.

His mind was oddly absent as the angel looked up at the opening, his exit to the human world, and heaven above. Arthur was oddly silent as his weapons were tested, his bow to his standards and his arrows loaded into his quiver. He looked over his shoulder at the demon king, gave him a weak smile that spoke to Al. "I don't want to go."

Even though the words were not spoken, he could hear them in his head. There was that pesky guilt again. He didn't remember the words he spoke to Arthur after that, but he was sure they were less than loving, judging by the look of disappointment on the angel's face that was burned into his mind as Arthur took flight.

Al stayed near the portal even after everyone else had left, stared up at the opening, waiting and watching for Arthur to return. It wasn't until his old friend rested a hand on his shoulder did he look away.

"Sire? You should come inside for dinner. You've been out here all day."

With a stiff shrug of his shoulders, he turned, and he and the pale demon beside him returned to the palace.
