Sebastian was preparing tea for when his young master when he realized it. He was trapped. While he had been putting the kettle on, a web had been woven around him. He cursed under his breath in his native tongue, causing an amused chuckle to sound through the kitchen. He turned his head the best he could, only grazing his cheek against the razor sharp thread. Unsurprisingly, Claude Faustus was balancing himself upon another thread, smirking down at his captive. Sebastian sighed, looking down at the kettle. "What do you want now, Faustus?" Sebastian sighed, looking at him with narrowed crimson eyes. Claude simply shrugged, "You, Michaelis." Sebastian's eyes narrowed, and he snapped, "What do mean? Do you wish to kill me?" Claude laughed, jumping down behind the other butler. "No, no, no. Not anymore. I wish to claim you as my own." His supernaturally long tongue just barely grazed Sebastian's ear, causing the slightly smaller demon to shiver. It would have gone unnoticed, had Claude not been a demon. Claude pulled Sebastian into an all too familiar pose, arms wrapped around Sebastian, one around his neck and the other around his waist. "The mating cycle is coming up soon, Michaelis. For three years now, we have both denied ourselves the search of a mate. We both know that a hand may keep it at bay, but don't you think that you should do better?" Claude spoke softly, knowing the demonic urges all too well. Sebastian snarled, even though his body was slowly responding to Claude's voice and soft touches. "I know better, Faustus. You must have known that this is the year of the four that if I mate, I am bound forever. I will not come willingly." He replied, voice even despite his anger. Claude's eyes widened just slightly. "Mm, I didn't, but now I do. That makes this deal all the better, considering I don't like sharing what is mine." Sebastian shuddered again, not even bothering to try to hide it this time. This was the point that Sebastian began to try and fight back, but Claude quickly subdued him, tightening the web around him just slightly. Sebastian had a sharp intake of breath that he barely even needed in this form, the way he had his cheek turned causing it to get slashed suddenly. Claude only smirked; hand coming out to dab away the blood. Sebastian sighed contentedly before he even realized what he was doing, humming under his breath like everything was going exactly as he had planned. Claude smiled, realizing just how easy it may be, come mating season. Just as Sebastian was starting to get comfortable, the low hiss of the kettle starting to boil more relaxing that he had remember, Claude disappeared, his web falling to the ground. Sebastian whirled, looking for his captor turned friend. He sighed, wondering if he had gone delirious. Yet, the slight sting of a healing over wound on his cheek said he wasn't. As he started to finish the tea, he wondered whether or not he really should accept Claude's offer. It would be much easier on himself, and his young master. He tried to convince himself that it would be out of mutual convenience, but in the back of his mind, he knew better.

It was one month later exactly when the mating cycle started. It was a three month long period of mating, at least it was in the universe that the demons hailed from. If it wasn't your season to be bound, one usually went through several mates a day. It caused problems and work never really got done. Demons fighting over desirable mates were a common occurrence. With the heat and the urge to mate, it was hard for anyone under contract to do the things they were ordered. However, Sebastian, for the first time in two years, was excused by his master. He had explained, as plainly as he could to the thirteen year old, what he was going through. Ciel hadn't excused him on sympathy, but rather the notion that a butler with nothing but sex on his mind was not a pawn that could be of use for that time. However, Sebastian was to check up on his young master regularly. Sebastian was relaxing in his usually unoccupied room Claude popped in. Sebastian, who had been indecent for about three seconds, was startled and instantly pulled on his clothing once more. "Some warning next time would be appreciated," Sebastian said in his usual, witty voice. However, in his mind, his body was urging himself to go forward and submit to the demon in front of him. He pushed the thought out of his mind, knowing that it was just the mating cycle that was doing it. Claude smirked a bit, "I got what I was hoping to see. Might I say you have a beautiful body." Sebastian scoffed, looking away from the other demon. "In this body, yes. You haven't seen my true form. It is revolting." He hissed sadly. Claude shook his head, sitting down on the side of Sebastian's bed and beckoning him over. The other demon slowly moved to where he was sitting on Claude's lap, looking up at him. "Yes?" He murmured quietly. "I have seen you in our native world. You are even more dashing in that form." Claude said comfortingly, though he was being truthful. Sebastian had bodies that even the most beautiful of demons would be jealous of. Sebastian allowed a hazy, pink hue to cover his cheeks, looking away. The fact that Claude was controlling his urges, and not claiming Sebastian at that exact moment, was what made up the smaller demon's mind. "I accept." He said simply. Claude contemplated what Sebastian was talking about for half a second before he grinned widely. "Are you sure? There is no going back from this." Sebastian nodded, lips curling up into a slight smile. "Everything I hated about you is not a reason why you are a good mate. You are strong, smart, and level headed. Plus, the fact that you can control your urges so well is impressive to say the least." They smiled at each other for a few moments before Claude snapped them away to a place more suited for what they were about to do.

Sebastian felt where he was before he saw it, gasping and hitting Claude's shoulder. "Why would you bring us here? We are both under contract!" Claude had transported them to the demon world, and they were standing in a large mansion. "I had everything prepared for you," Claude explained with a smile. He gestured to two, large bells that were hanging in the foyer. "I have these rigged up so that if either of our young masters ring for us, we will be alerted." Sebastian grinned, leaning up and placing a not-so-chaste kiss onto Claude's cheek. "Continue, then," Sebastian purred happily. He could sense other demonic presences in the household, causing him the raise an eyebrow. Everything clicked into place and he smiled. "Claude Faustus. I should have known you were a demon lord. It all makes sense now!" Claude smiled a bit, shrugging as he started to walk down the stairs. "I figured you knew. I know you are the son of another demon lord." Sebastian blushed a bit, tugging off his one of his gloves with his teeth. "I was trying to hide it, but I guess it didn't work out." Claude raised an eyebrow as they made it to a cellar like room. Claude put Sebastian on a bed in the corner, going back and locking the door of the cellar. "Nobody will bother us, but just in case…" Claude explained as he walked back. They smiled at each other before Claude slowly placed his body over Sebastian's. Despite the heat only being in season for a few hours, it was already increasing in their bodies, making Sebastian's hips jerk up into Claude's. They both shuddered with pleasure before Claude was initiating the first kiss they would have as mates. It was soft and sweet at first, both of them knowing that it was going to be the start of a serious relationship. Lifelong mates were the closest relationship demons could get in. The only person a demon would truly submit to would be its mate, not even the king would stop them if that is what they wished. Anything short of death was not enough to get them to submit. Sebastian put all of his thoughts aside, fingers threading through Claude's hair. Claude smiled, dragging a bit of his tongue across Sebastian's lips. In a lapse of thought, Sebastian opened up without protest. The heat was clouding his mind to the point that he couldn't do anything but comply. One thing that could be said about demons during a mating cycle…There was no such thing as one getting raped. Both parties enjoyed it too much. Claude's impossibly long tongue made its way into Sebastian's mouth, wrapping around his own tongue easily. The smaller demon moaned slightly, rolling his hips up into Claude's. The latter smiled a bit as he repeated the action. Sebastian smiled a bit, pulling back from their kiss reluctantly. "C-Clothes," He panted, regretting the idea to speak as he stuttered. Claude smiled, and in the blink of an eye, both of their uniforms were torn and thrown to the floor. Both butlers knew in the back of the mind, that eventually they would regret that action, but at that moment, they didn't care as their cock's met and created a delicious friction. They both moaned heatedly, and they were both reaching down. To Sebastian's delight, he was beaten by Claude, who wrapped a large hand around both of their members and starting to stroke. Sebastian gave another moan, raising his hips proactively. Claude, no matter how much he loved Sebastian's moans, quickly covered his lips with his own. "I'll fuck you hard and fast if you keep moaning like that," He explained against his lips, tossing his spectacles to the side. Sebastian smiled at that, realizing that they both wanted their first time to be slow and soft. "You are too perfect." He replied.

In a haze, they soon found themselves with Claude's somehow lubed up fingers at Sebastian's entrance, pushing in slowly. Sebastian moaned, spreading his legs wider as he encouraged the entrance. Sebastian was a lot younger than Claude was, about 5,000 years, but neither really cared at that moment. The only thing that meant was that Claude was more experienced, making him a wonderful lover for Sebastian. The two complemented each other quite nicely, they would realize. Claude started to splay his fingers around Sebastian's entrance, humming softly as he absentmindedly took Sebastian's weeping cock in his hand. "Mm, so hard for me, my mate." He whispered, even though Sebastian would be able to hear him anyways. Sebastian panted, looking up, smiling brightly. "Only for you, now and forever," He whispered back, wetting his suddenly dry lips. They smiled a bit, but Sebastian's quickly dissolved into an open mouth with a moan leaking through as Claude pressed his fingers against his prostate. Claude smirked at the reaction, continuing to put pressure against it for a few moments and pulling out his fingers. Their bodies were built for sex, so a little bit of sexual pain wouldn't even hurt them. Claude lined up, stroking the pre cum to wear it lubed him up entirely. "Are you sure you want to do this, my mate? There will be no turning back." Claude asked, biting his lip. He knew that he would have a hard time pulling away if Sebastian changed his mind, but he would manage it. He could already feel a smile burst of love in his heart for the demon in front of him, and he wouldn't be able to hurt him ever again. Sebastian took one of Claude's hands, smiling a bit. "If you don't make love to me right now, you may find a knife at your neck." Sebastian replied happily. Claude laughed, leaning down and pecking his lips as he pushed in. Both demons moaned, overwhelmed by the pleasure. Sebastian felt the pain of not being completely prepared, but he didn't even care, the pain only proving to make him even harder. Claude pushed in all of the way, squeezing Sebastian's hand with pleasure. They both made eye contact, eyes flashing their demonic red as their link formed. Sebastian was moaning suddenly, and Claude was too. The link was always a pleasurable experience for life mates, something that was placed even higher than eating a high quality soul. It was a loving experience, and the two shared a soft kiss as Claude slowly started to pull out. Sebastian whined, but it was cut off as Claude stopped half way, pushing back in. That was a start of their rhythm, both of them feeling unfiltered pleasure. Their moans were filling the entire house, Sebastian knew in the back of his mind, and he couldn't help but smirk. Let them all know that they both had found their life mates. It only made things easier on both of their ends: Nobody would approach them at least until they got a wiff of the other's scent on them. Through their link, they were both marked with the other's scent. It also allowed them to sense out where their mate was, no matter how far away. It was a bond that very few demons pursued, and Sebastian really couldn't understand why. Why didn't demons want to fall in love with somebody that is important to them? It was such a rare occurrence that most of the other species assumed that demons couldn't love in the first place. Sebastian was ripped from his thoughts almost violently as Claude started to stroke him teasingly. Sebastian whined at his mate, feeling his prostate start to get hit softly and slowly. Claude seemed to know exactly what he was doing to his mate, a smirk across his lips as he continued his slow pace. Sebastian started to buck back against him, body starting to shift between states with pleasure. Claude quickly grounded him, taking his hand again. Sebastian remained in his human form that moment on, still ashamed of his demon form despite what Claude said. Sebastian, from his inexperience in these things with other demons, didn't last for very long, hips starting to jerk around erratically. "I-I'm so close," Sebastian whined at his mate. Claude smirked a bit, continuing to stroke his cock slowly but increasing the pace of his thrusts ever so slightly as he allowed himself to teeter in the edge as well. "Cum with me, mate." Claude growled huskily, causing Sebastian to orgasm instantly. Claude quickly came inside him, but not before he elongated his fangs and stuck them into Sebastian's neck. The younger male moaned in reply, baring it openly. The exchange of blood was something only lifelong mates shared in, and it was something both members treasured. Sebastian bit down on Claude's shoulder, both of them moaning at the taste and feeling of having their blood sucked.

It was minutes later when both demons came down from their high. Somehow, Sebastian was snuggled firmly into Claude's side, his head on his chest. Claude had an arm wrapped around him, and they were both smiling. "You are mine now, Sebastian." Claude reminded with a content sigh. Sebastian nodded, "As you are mine, as well, Claude Faustus." They both grinned, and Sebastian leaned up. They shared a soft, chaste kiss, both of them unbelievably happy. And to think, Sebastian thought as they continued to kiss, that I originally only waited to do this for a simple gain. As their lips departed and Sebastian returned to his original place, neither said a word. Their exchange had already spoken for them.

Hey guys! It's the author! This was not a spontaneous smut. There will be bondage, and maybe even a little more different kin's of mine. Just maybe c:. Tell me what you think, if that is what you wish. If you see a typo, please feel free to tell me.
