A/N: The more comments you live, the more likely random BS like this is to spawn (the comment on one of my other fics that inspired this was literally just "Well that's one way to avoid stds or mpreg! Lol!" LOL wtf is my brain doing)

Summary: Don't stick your dick in crazy, or they may make clones of you.

"Let me do it to you this time," were the leading words to his current situation, which was the young master sliding in and out of his arse. He had agreed begrudgingly. Truth be told, he did not fancy being dominated, taken by such a tiny creature, unless it benefited him in the long term (for example, mental manipulation by making the top feel like they're in control because they were the one penetrating, when in reality, he was still in control). But his young master's wishes were his to fulfill. So here he was, getting fucked by a boy with not even a fraction of his age or height or experience.

He refused to show any enjoyment out of it, not like Ciel particularly cared. Despite the years that went by, Ciel seemed to be stuck, unaging, in the same body on the day that his contract with Sebastian was sealed. The Faustian contract did tend to have some unusual side effects that came along with it, such as feeling pain when disobeying a direct order or the tug one felt when their master called their name. Perhaps being frozen in time age-wise was yet another.

So a tiny boy with the brain of an 18 year old and the wisdom of one much older was taking hold of his body and using it like a tool. Which, technically, Sebastian was in the eyes of Ciel Phantomhive. A tool, to be commanded and serve his whims until his contracted desire was fulfilled.

In, out, in, out, sweat transferring between slaps of his thighs against the older man's rear. Awkward moans that sometimes cracked because the boy was forever trapped in a just-reaching-puberty state. Sebastian couldn't help but smile; the act of fucking him seemed to take so much energy out of the boy. Ciel grabbed desperately at his muscular thighs, frantic movements increasing in speed and rhythm starting to break as he drew near.

As he laid back and thought of Hell, he also wondered if the Faustian contract prevented new muscle growth that came from exercise (as if his young master would ever actually do such a thing) or muscle memory that came from repetitive actions (such as dancing or playing an instrument over and over), which would also apply to the not-aging deal. If that were the case, the young master truly wouldn't be able to retain anything physically that the demon tried to teach him. Given that Ciel demonstrated the ability to maintain memories, he had an idea that it wasn't as simple as that.

The boy let out a shout as he reached his peak, shooting a generous amount of his life essence into Sebastian. Sebastian would have much preferred to have had it in his mouth, because at least he'd be able to get something out of—tasting his master's soul through his sperm. He enjoyed oral very much because of this, even though Ciel saw it as a degrading position. If the boy actually bothered to try it, he might see differently. The brat wasn't fond of putting himself in that position, though.

Ciel, spent, held himself up with wobbly arms, refusing to fall on his servant. After a moment to recuperate, he pulled himself out, hissing from oversensitivity, and staring down to see a bit of his cum escape with the movement. The hole, raw and red, clenched on emptiness.

"Satisfied?"

"Yes," the boy muttered, moving from his kneeling position on the bed to stand on the floor. Afterwards, the demon would shower the boy, cleaning him of sweat and semen, dressing him, and prepping him for a good night sleep.

Ciel had developed an obnoxious quirk in their sessions together.

The little tart loved orgasm denial. Not for himself, no, but for the demon.

As time went on, the boy had gotten more experienced in the practices of control of one's bodily functions, through experience as well as behind-the-door conversations. People were disturbed that he remained so small, and even Lady Elizabeth couldn't find it within her to bed her to-be when he still looked like a child. With this in mind, it was hard to hear conversations about raunchy sexual interactions, yet the boy managed. He could disappear in a crowd due to his short stature, and oftentimes strangers wouldn't bother censoring themselves around kids to begin with.

Unfortunately, that meant anything Ciel learned must be put into practice using Sebastian as the guinea pig. It also meant that Ciel could actually draw out arousal in Sebastian despite Sebastian finding himself on the bottom.

The demon hissed as Ciel pulled back yet again. "I remember a time where I had to command you to cum," he stared down his nose at the butler, who lay with his chest and lower body exposed with a thin sheen of sweat coating his skin. "Now you struggle to because you can't." He flicked at the demon's dick, which was an angry red and begging to trickle pre-cum, but with his master's orders, not even that was given to him. The demon's hips jerked in response, trying to get away from the boy's taunting. Such sharp, brief touches were unusually painful in his exhausted aroused state.

"You're still not allowed to come," he mentioned offhandedly as he began walking toward the washroom. "In fact, I don't think your needs need to be attended to for the rest of the day."

The boy had been frustrated at the butler for denying him sweets that day. Of course, the boy didn't need the sweets at the time. He would have spoiled his appetite for dinner with the heads of a prospective toy company who wished to do a joint collaboration to spread Funtom Company products to other countries overseas. The boy could make a mountain out of a tiny hill of sand, and that often manifested in their sex sessions.

What a brat.

Normally, he could just will the arousal away, but as his master commanded him to not attend to his needs, he was forced to suffer with lust clouding his mind and a boner that would surely be visible to anyone who dared to look down.

Sebastian decided to do what demons were natural pros at—exploiting people's words. In one past instance, he'd used the fact that "rest of the day" was subjective. "Rest of the day" could mean until a certain hour went by in which day was then considered night, or when Ciel went to sleep. In another instance, he used the fact that day could also mean when the sun was going down (and in another instance, when Ciel wasn't specific enough, when the sun had set completely). Since the boy had clarified multiple variants, Sebastian now had to wait until 00:00hrs (which was considered a new day) before he could will the arousal away. Of course, if the young lord was still frustrated the next morning, he completely expected his young lord to take that away from him as well. Considering Ciel didn't get his way with food all of the time, and had thus come to grow less enraged with the denial of unnecessary consumption of sweets, Sebastian imagined that he wouldn't lose those privileges this time.

Sebastian briskly clothed himself, frowning at the tent that pitched his pants in an offensive display. He'd simply have to choreograph his movements and positions so that the other staff in the manor wouldn't be able to see it. Easy enough.

He prepared the boy for bed, who kept staring and snickering at his raging hardon like a child, like it amused him to see Sebastian uncomfortable and in pain. But Sebastian managed.

When that was finished, he left to do his final tasks for the night, avoiding the staff members (who thankfully did not blow something else up in the house or ruin something so badly that it required his assistance). Truth be told, the lust in his mind was making it harder to concentrate, so he opted to lay stiffly in his bed to wait until the minute hand shifted from 11:59 to 12:00.

He watched the clock, looking dead to the world, but his mind was racing. Conjuring up countless potential sexual fantasies involving anything he was willing to claim. His hands itched to paw at his cock, which had been hard for hours, but through the will of his contract, he persevered.

Violate this, sodomize that… his mind started circling around his prissy light-haired master, and then a peculiar thought crossed his mind.

Unbeknownst to Ciel, Sebastian had stored the boy's semen rather than purging it with his demonic powers. Initially, he was going to purge it once the new day struck, as expelling foreign objects inserted by his master may have constituted as "taking care of his needs", but he paused.

The boy only ever approached Sebastian when the boy was interested in a romp. While demons could control their sexual urges without fail, that did not mean that things around them did not pique their fancy. And Ciel, at certain times, definitely stimulated the demon's hunger.

Sebastian used the semen in combination with his demonic powers to form a clone of Ciel, which took roughly five minutes from the start of 12:00. The majority of the mass grew within his stomach before it was large enough to begin separating from the demon's body like goo being pulled apart. It wasn't something Sebastian employed often; it did take up a sizeable portion of his energy, and there were limited instances where it was actually useful. The clone often lacked greater intelligence and dissolved within an hour, only having so much energy imbued via Sebastian.

Because he had a lot of sexual frustration, he vented a lot of that energy into the clone, whose eyes snapped open and revealed a fire in them that Sebastian rarely got to see in his true master's gaze.

The clone didn't seem resistant to the demon's advances. Rather, spurred on by transferred sexual desire, it gripped awkwardly at Sebastian's clothes, trying to take them off. Instead of allowing the clone the role of taking the lead, he gripped at the boy's head and shoved it downward, smashing its face into his still-clothed erection. Ciel would never stand this action happening to him, but the clone didn't have much of a choice in what happened to it.

The clone struggled, familiar hands pushing against Sebastian's waist, as it didn't appreciate the roughness, but the struggling and shifting of the head only served to increase Sebastian's simmering arousal. He ground that groin into its face just to show that he was in control of this situation, before releasing the clone's head to pull down his pants to reveal the staff that had been at mast for hours now.

That clone's mouth was forced to take it in. The clone gagged as the too-large mass hit the back of its throat. Sebastian purred at the sight of his master struggling to follow the pace, unflattering expressions crossing its face that had him moaning and pressing further down its throat. The gagging caused contractions around his length; the noise only sent more blood rushing to his cock.

His mind drifted back to instances where Ciel displayed the effects of fear. Heart pumping wildly, dilated pupils and flinching movements that attracted the predatory instincts within the demon.

If the clone would last longer than an hour, it surely would have had bruising all about its face thanks to the punishing pace in which Sebastian fucked its face. Fingers gripped its head too tightly, spit flying everywhere from the point of contact, noises of genuine discomfort filling the air in conjunction with those feral, demonic growls.

He fantasized about his master potentially fainting around his dick if he didn't let the boy breath. Limp lips forming about his rod, painting the back of his throat with his cum… Claiming his soul right after that…

The thought of his master, dead on his cock, had his balls twitching toward his body. With a hand clenching that fine blue-grey hair, he pulled the clone off his dick, which prompted hellacious coughing and gasps for air. The clone's eyes were tinged with tears and Sebastian groaned at the sight. His master was so pretty when he was like this…

With a few tugs to his length, slapping it on the side of the clone's face several times, it released its load, drizzling that young face with his essence. It coated its hair, nose, mouth, even beading like pearls on its eyelashes in a desecrated sort of way that had Sebastian wanting a second round and desiring the real thing. This would fade away in less than an hour. He wanted the experience to cause an impact, for his master to carry it with him for the rest of his life that his demon butler was the only one able to mark him like this. No one else.

The poor clone was ravaged for the rest of that hour.

In the morning, it was as if nothing had happened. Ciel woke up without irritation from the previous night, and Sebastian's appetite had been whetted. The demon dressed the boy for the day to come. While doing so, his mind wandered as it often did.

He thought about potential scenarios he could enact in the future. The clones really were a good way to take out his frustrations when his master decided to top him. As he couldn't redirect his aggression onto his master as is, the clones were the perfect tool for him. He thought about what he could accomplish if he extended their summon time, and what if he gave them more personality or function. He even briefly fancied the idea of Ciel catching him in the act of defiling multiple clones at once. The more sperm Ciel gave him (whether orally or anally), the more he could do with the clones. The more intelligence he could give, the longer they could stay spawned, the more he could create at once.

Thinking about it, he couldn't wait for the next time Ciel fucked him.
