Chapter Text
“Are you here, Undertaker?” Ciel’s voice echoed around the dimly lit funeral home, eye squinting and searching the darkness. A beam of light illuminated in a line as the door opened, then was gone again as it closed when Ciel and his butler entered.
The boy heard the sound of the familiar laugh from somewhere in the darkness
“He he~! Hello again, Earl~” The muffled voice called, and one of the lids of the many coffins against the wall swung open.
“Every time ya visit, i always hope it’ll be for one of my fine coffins ‘ere~ alas, i know you’re here for somethin different aren’t you, little earl~?” The Undertaker spoke as he stepped out from the coffin and closed the lid behind him.
“You know why we’re here, then.” Sebastian guessed, standing just behind Ciel. “I assume that means you have information?”
“Hmm~ do i~? I don’t know, i might just.. for the right price~”
“Ah, yes. Your usual, I presume?” The demon assumed once more.
Both Ciel and Sebastian figured the Undertaker was after his usual medicine; laughter. Both were surprised when the Undertaker tilted his head and spoke. “Actually, mister butler, i have a different request.. specifically of you. Just some things i need help with. Earl, do you mind if steal your servant from you for a few hours?”
Ciel’s brow raised suspiciously and the Undertaker grinned. “Don’t ya worry, little earl. I’ll return him quick and proper when Im done; with the information of course~”
Sebastian looked down at his young master, who sighed. “Fine then. Sebastian, help the Undertaker and return with the information. I’ll wait at the manor.”
The demon bowed. “Yes, my lord.” He said calmly, straightening up as the boy turned to leave.
“Oh, earl?” Undertaker called, and Ciel paused to turn. “Turn the sign to closed on your way out, would ya~?” He requested with a grin. Ciel merely nodded, though his eye narrowed, and he stepped out of the parlor.
Sebastian turned towards the Undertaker expectantly, his head at a slight tilt.
“What is it you require of me?” He asked calmly, looking unbothered, if a little confused. “You said you needed help?”
“He he he~ I’m afraid I may of misled ya a little, mister butler~ I require.. a different kind of assistance~ just didn’t wanna say it front of the young lord. Ruin his innocence yanno~”
Sebastian’s eyes widened a fraction, and he seemed to understand. He let out an amused huff through his nose. “I see. Your.. preference comes as a surprise to me.” He said carefully, seeming throughly amused. The Undertaker wanted a hookup. With him. How ridiculous.
Not unheard of for the demon, of course. He had pleasured man and woman. It wouldn’t be a problem.
“Ehh, don’t really got a preference. Man, woman, whatever. I picked you cause you’re a decent lookin fellow. You seem to know the desires of humans well~ made sense.”
Another amused huff. “I see.” He said, watching as the Undertaker led him behind a curtain in the back of the parlor. This seemed to be a more.. homey area. There was a desk, a bed, a small kitchen, some chairs and a table. There was another doorway, with an actual door this time, that seemed to lead to the embalming room, based on the smell.
Because Sebastian was so distracted with his surroundings, he barely realized Undertaker was stopped in front of him until he felt a hand on his tie, and then that hand tugged him forward. A kiss, a feverish, heady kiss, lips and tongue. When it ended, Undertaker tugged at the tie, and Sebastian got the message, pulling it from his neck and starting to work at the buttons of his coat. He removed and folded his tailcoat and vest, and had just pulled off his belt, when the undertaker spoke. His voice was.. soft, like velvet. Silky and sweet. Elegant, almost, compared to before.
“Lay on the bed, back on the pillows, if you don’t mind~” He requested.
Odd, the demon thought, but complied, lying back on the collection of soft pillows. He noticed undertaker had removed his hat and outer robe, leaving him only in the cassock underneath.
“Hands above your head~” the Undertaker requested next. Again, odd, Sebastian thought, especially when the other man grabbed his wrists, not only tying them together, but to the bed frame with a long piece of rope. Sebastian gave an experimental tug. It was tight. The rope would leave marks if he pulled enough. Not that he couldn’t break it if he so desired, but curiosity got the better of him, and he simply watched the man.
The Undertaker crawled over him, straddling his lap. He leaned down, starting to trail kisses and bites along the demon’s neck, unbuttoning the butlers shirt as he went along, and Sebastian felt a long tongue against his collarbone. As well as.. some sort of metal?
“A piercing?” He asked curiously. “I didn’t expect that from you.”
“Mm, got bored one day.”
“You did it yourself?”
“Course. There ain’t many places to get it done. Wasn’t too bad.”
“Hmm..”
The Undertaker’s lips moved down to Sebastian’s chest, dragging his tongue, and the piercing, against his nipple, fingers toying with the other. Sebastian tried not to squirm, breathing slowly through his nose. He didn’t /need/ to breathe, of course, but not only was it to keep up appearances, but it helped maintain his composure against the unusual feeling.
While Undertaker’s mouth was busy, his hands worked to unbutton Sebastian’s trousers. He slipped an arm under the demon’s hip, pulling his mouth from his chest and lifting him easily, and sliding his trousers off. Sebastian’s eyes widened a fraction once more. He wasn’t used to being manhandled like that. And most embarrassingly, he was already half hard. This stupid human form betrayed him.
It wasn’t long before he was fully hard, either. One of undertaker’s delicate hands wrapped around him, stroking his cock lightly, rubbing against the tip. Sebastian tried not to tug against the bonds on his wrists, but it was difficult. This was certainly not what he had expected.
His eyes closed as he laid his head back on the pillows. He didn’t open them, even as the hand disappeared. He only looked when he heard the sound of.. latex?
He looked at the Undertaker and saw him slipping on a glove, and holding a bottle of.. something. Some sort of lubricant. It only clicked for the demon when he saw the Undertaker pour the liquid onto his fingers, rubbing them together before settling between Sebastian’s legs.
“What are you doing..?” The demon asked, almost sounding panicked. This was certainly not what he was expecting.
“Don’t worry, Sebastian~” the demon blinked as he heard the Undertaker use his given name for the first time. “I’ll be gentle~ you’ll feel good, I promise~”
“I’m not so sure about that.. I, uh..” Sebastian felt.. what was it, nervous? Unusual. This was nothing to be nervous about. And yet, he was almost stuttering.
He felt the fingers lower, rubbing lightly at his entrance before one slipped in. Sebastian bit his lip at the slight discomfort. Slow, rubbing, curling. Then another slender finger. The discomfort had disappeared at this point but it still felt.. odd. Not quite pleasant, but not unpleasant.
Unusual. Unexpected. Nerve wracking.
Undertaker grinned as he curled his fingers precisely.
Sebastian’s eyes shot open and his whole body jerked, an embarrassing sound being wrenched from the back of his throat.
“Ahhh, there we go~ good~” Undertaker praised, pressing hard against his prostate, rubbing gently. Sebastian squirmed, as if trying to escape from the intense feeling, eyes screwed shut. Undignified sounds fell from his lips and Sebastian resisted the urge to remove himself from bonds only to cover his mouth. He did what he could, pursing his lips and almost hiding in his arm.
“Now now, that won’t do~ come on, Sebastian~ just relax~ it feels good, doesn’t it? Let me hear~” He was practically purring against Sebastian’s ear, thrusting his fingers quick and precise, right into his prostate, over and over.
Sebastian’s back arched slightly, and he couldn’t help but moan, embarrassment burning in his chest. “A-ahh~ oh~” He groaned, squirming.
Undertaker was grinning as he watched him fall apart, moaning and squirming helplessly. He could tell he was close already from the way the demon tensed.
His eyes opened and widened again as he felt a hand start to stroke him in time with the fingers inside him. It was too much, the demon couldn’t handle it.
Unbelievable. Him unable to handle something. But he was.. overwhelmed.
“A-ah~ wait~ I- ngh~!” Sebastian threw his head back with a load moan, a shudder wracking his body as he came. Undertaker didn’t stop until he was almost to the point of overstimulation, finally slipping his fingers out.
The demon was panting. He was burning with embarrassment, shame. From not only being debauched so throughly, but from enjoying it so thoroughly.
He barely got a break though as Undertaker was removing the glove and partially undressing himself, only unbuttoning the cassock enough to expose his own hard cock. He settled between the demons legs again, lifting them slightly, holding them around his waist. Sebastian swallowed as he watched him, almost feeling weak.
It was slow at first. Inch by inch, sebastian felt the undertaker press into him, feeling himself stretch to accommodate. Another strange feeling. His head fell back against the pillows, his mouth falling open, eyes squeezing shut. When the Undertaker was fully settled inside him, he paused for a moment, and Sebastian had to try not to squirm. With every minute movement, he could feel him, deep inside, and it almost made him shiver.
And then he started moving. Again, it was slow. Every small thrust pulled another embarrassing sound from the demon, and it only got worse when the speed increased. It didn’t take long for a pace to be set, consistent, hard thrusts, pulling sweet sounds from the butler.
Undertaker angled his hips with one particularly harsh thrust, and Sebastian practically cried out. After that, he was met with an onslaught of harsh, fast thrusts against his prostate. Merciless, overwhelming. Sebastian was squirming, hands clenching and unclenching, tugging against his bonds, head lolling from side to side as he tried to process the intense waves of pleasure.
Undertaker whispered something, but Sebastian didn’t process it as a warning until the other stilled inside him, and he felt hot liquid pouring into him. He shivered, groaning quietly. And then undertaker was slipping out of him.
“Beautiful~” He whispered, and Sebastian again hid his face in his arm.
“Afraid I’m not done quite yet, though.” Undertaker continued, easily flipping Sebastian over so he was on his knees, chest against the bed. Undertaker pulled his hips up, gripping them tight as he slid back inside him, and Sebastian let out a wobbly moan. At least now he could hide in the pillows.
Which he did. He moaned into them unabashedly as Undertaker rammed into him. At least, until a hand gripped his hair and tugged his head up. Undertaker pulled him to sit up on his knees, Sebastian’s back to the others front. One hand wrapped around his waist to hold him there, the other stroking his cock along with his thrusts. Sebastian’s head lolled back onto Undertaker’s shoulder, practically moaning into his ear. Sweet words and praise dripped from the others lips as he watched the demon totally fall apart under him.
And when the demon tensed and came for a second time, the other followed suit, holding him there for a moment before he let go. Sebastian collapsed onto the bed, legs shaking slightly. He was panting, heaving for air he didn’t need. His whole body was alight. He had never felt this before, not in the many times he had sex beforehand. Although, he hadn’t been so submissive those times.
He felt weight on the bed shift as Undertaker slid off the mattress, and the demon turned to lay on his back, staring blearily at the ceiling. He was surprised when undertaker returned with a warm, damp cloth and started gently cleaning the come from Sebastian’s abdomen and thighs.
“There, that’s better, isn’t it?” Undertaker practically cooed, and Sebastian sat up, looking at him curiously. He was trying to get his bearings. “Yes.. thank you..” he muttered.
“Naw, don’t thank me. Basic aftercare, dear~” he said with a grin, seeming totally unbothered, and Sebastian nodded absentmindedly as he gathered his clothes and started to dress himself. He swore his legs were shaking still as he stepped into his trousers.
When he was finished and looked presentable again, he turned to the Undertaker.
“So.. what information did you have?” He said expectantly.
“Ah, yes! I almost forgot that’s what you’re here for. Come on.” Undertaker said cheerfully as he led him to the embalming room.
Sebastian was used to these smells at this point: They attacked his nose every time he entered the parlor. But there was a new one this time, a distinctly unpleasant one. It made his nose scrunch.
He looked at the woman on the table, the same one from the picture Ciel had shown him earlier.
“What is that smell?” He asked the Undertaker, who turned to him and grinned. “Glad you noticed it too. That’s this lasses true cause of death. Mistaken for a heart attack.”
“What is it?”
“A poison. Aluminum Phosphide. Practically undetectable in regular autopsies, symptoms mimic acute heart failure. This lass ain’t the only one either.”
“Interesting..” Sebastian murmured thoughtfully, pulling his pocket watch from his breast pocket.
“Oh dear..” he murmured.
“Hm?” Undertaker questioned, looking at him.
“I fear I may have left the young master far too long.”
“Have you?”
“You promised a few hours. It’s been four.”
“Has it really? Dear me~” Undertaker grinned, clearly unbothered by the realization.
Sebastian sighed. “Thank you for the information..” He said with a slight bow, turning to leave.
“Oh, mister butler?” Undertaker called, and Sebastian paused. “Do let me know if you ever want an encore~ I’d be all too happy to oblige~”
“Right..” the demon mumbled as he slipped through the curtain and out the front door, the bell on the frame jingling cheerily as the door closed.
