SebastianxCiel NSFW. I think I remember someone on Tumblr asking for a story like this a while back. I don't own Kuroshitsuji or anything.
Sebastian heard a knock on his dressing room door. "Come in," He called gently. Probably another desperate fangirl. He thought as he slid on his fake wedding band.
The door opened, and Ciel stepped into the room. "Um… Mr. Michaelis?"
Sebastian looked at the young boy, and his eyes grew wide. He smiled warmly. "You can call me Sebastian."
"Oh, okay, Sebastian." Ciel smiled back. "I'm Ciel."
Sebastian walked over to the couch, patting the cushion next to him. Ciel sat down hesitantly. "How old are you, Ciel?"
Ciel swallowed hard as he looked at his idol, less than a foot away from him now. "I'm eighteen." He said. It was true—despite his small size, today was his eighteenth birthday. His friend had bought VIP tickets to one of Sebastian's concerts for him.
"Really?" Sebastian smiled, leaning closer to his shaking fan. He looked into Ciel's deep blue eyes. "Why are you here, Ciel?" He whispered.
"I, um… I don't know. I thought we could just, you know, hang out or whatever."
Sebastian sighed mentally at the boy's awkwardness. He could tell from the way Ciel blushed and quivered that he had come to see him for a very specific reason. "What would you like to do?"
Ciel involuntarily scooted away from Sebastian slightly. He looked at his lap, where his hands were folded neatly—the result of years of lessons in proper etiquette. Ciel made a conscious effort to slouch, in an attempt to relax. "I'll bet you get a lot of girls, right?"
Sebastian laughed softly. "Women do tend to throw themselves at me, yes. They're always quite disappointed when they see this." He held up his hand, showing Ciel the ring.
Ciel's heart sunk. "You're married."
"No, not at all." He slipped the ring off of his finger, tossing it onto the table with a clink. "It just gives me an excuse to shoo them off."
"Oh," Ciel breathed.
"Would you like to take a guess as to why I constantly reject beautiful women?" Sebastian grinned devilishly. He waited for Ciel to make a move—that's how Sebastian worked. A young man would approach him, and Sebastian would tease the boy, flirting with him, reeling him in, until his prey couldn't stand it anymore and gave in. Of course, sometimes they got tired of waiting and left, but Sebastian didn't mind; there were plenty of them eagerly awaiting his attention.
He stared at the boy in front of him—or more like below him, by then—and something strange happened.
Sebastian realized he wanted Ciel.
He wasn't the predator in this situation. Somehow, this awkward teenager had ensnared him, and he wanted Ciel with all of his being. He tried to control himself, to make Ciel come to him, but he couldn't resist.
Ciel's heart fluttered as Sebastian took his face in his graceful hands, pulling him into a deep kiss. It didn't take long for him to respond to Sebastian's expert technique; he threw his arms around the older man, kissing him desperately.
Sebastian, plagued with animalistic lust, pulled Ciel's shirt open, popping several buttons off and exposing his smooth chest. He panted as he ran his slender fingers over the boy's flawless skin. Lowering his head, he sucked one of the nipples into his mouth, gently biting at the tender flesh.
Ciel gasped as Sebastian gnawed at his body. He had waited for this moment for so long, and now all he could do was sit there, breathing raggedly. He pushed Sebastian off of him, and sat on the floor in front of the man.
"Ciel?" Sebastian watched as Ciel removed the remains of his tattered shirt, and started to unbutton his own shirt. He watched as Ciel moved closer to him and situated himself between his legs. With shaking hands, Ciel reached up and unzipped Sebastian's pants.
Sebastian moaned when he felt Ciel's cool hands grip his erection through his underwear. He lifted himself up and slid his pants off along with his underwear, leaving him completely naked on the couch.
Ciel's eyes widened when he saw Sebastian's penis—it had to be at least eight inches long, and it was thick. He opened his mouth, and gently licked the head of it, eliciting a moan from Sebastian. Trying to relax his jaw, he worked it into his mouth and started to suck, like he had seen lots of men do in the videos he'd watched to prepare for this.
Sebastian looked at the boy in awe—he wasn't very good at sucking cock, but his soft little mouth still felt amazing. He took his discarded shirt and looped it around the back of Ciel's head, pulling him further onto his dick. Sebastian leaned his head back and closed his eyes, letting Ciel worship his cock.
Ciel looked up, watching Sebastian's face contorted in pleasure. He pulled back, letting his erection fall out of his mouth and causing Sebastian to open his eyes. Ciel stood and fumbled with his belt, trying to remove it.
Sebastian snickered at the boy, and had the belt on the floor in a second. He yanked his pants down, and sucked Ciel's cock into his mouth before he could protest.
"N-no, don't! I'll—ah!" Ciel squealed as he came, and Sebastian eagerly swallowed his sweet juices, sucking every last drop out of his young lover. "I'm sorry, I've never done this before."
Sebastian pulled back, and looked up at Ciel in surprise. He could tell that he was inexperienced, but he didn't expect him to be a virgin. "Never? Not even with a girl?" Ciel shook his head, and Sebastian grinned. I'm going to destroy this kid. I'm going to make him mine. "It's alright," He assured the teen, pulling him onto the couch on his hands and knees. He sat behind him, admiring Ciel's bare ass while he wet his fingers.
Ciel laid his head against the arm of the couch. He knew what was coming next, and he tried to relax his muscles. He let his eyes fall closed, and took deep breaths. "Ah!" He yelped in surprise and his eyes flew open at the feeling of Sebastian's fingertip against his anus.
"Shh," Sebastian soothed, pressing his finger into Ciel's ass. His cock lurched as he watched the digit slide inside. "Good boy."
Ciel trembled as he felt the invasion. It hurt, but it also felt good in a strange way. It was like a tingling warmth deep inside of him, bringing his erection back to life. "Mm," He grunted, biting his lip, as Sebastian added another finger. He started to slide his fingers in and out, slowly at first and then more rapidly, delighting in Ciel's panting and moaning.
Sebastian removed his fingers, and licked Ciel from the tip of his now-hard penis all the way up to his anus. "Are you ready?" He whispered, leaning over Ciel.
"Wait," Ciel groaned. He turned himself over onto his back, and lifted his legs. "I want to look at you when you… fuck me." He blushed as he said the words.
Sebastian almost came right then, and he moved forward to kiss Ciel passionately as he rubbed the head of his cock against his opening. He pulled back to look at the teenager as he pushed himself inside.
"It... hurts…" Ciel moaned, gripping Sebastian's arms tightly.
"I'm sorry," Sebastian whispered as he tried to control himself and be gentle. He stopped when he was halfway in, letting Ciel get used to his girth. Sebastian glanced at the young man's throbbing member between them. "It'll feel better if you touch yourself."
Ciel hesitantly reached down, embarrassed to masturbate in front of someone, and began to stroke himself. "Oh," He sighed—it did feel much better. "You can… move some more."
Sebastian complied, and pulled himself out almost entirely before shoving in again, this time a bit deeper. Ciel moaned deliciously, and Sebastian started to speed up. He tilted Ciel's hips as he moved forward, pressing their chests together. He bit Ciel's neck gently, and the boy wrapped his legs around Sebastian's waist, pulling him in further. He tangled the fingers of his free hand in his lover's hair, grunting with every thrust.
"Sebastian… I'm going to…" Ciel groaned loudly when Sebastian pushed his entire length in.
"Do it," Sebastian hissed. "Do it now. Come."
Ciel's cry of orgasmic bliss was cut off by Sebastian's lips. He drove in one last time, and came deep inside of Ciel. Their bodies shook and twitched as one, and they held each other tightly, panting into each other's ear.
After a few minutes, Sebastian pulled his softening penis out of Ciel's ass, causing Ciel to moan in pain and discontent.
Ciel watched as he stood, wiped his cock, and began to dress.
"Find your clothes. My manager should be here soon." Sebastian ordered. He noticed Ciel's face. "What's wrong?"
"That was… You were amazing." Ciel whispered. Sebastian bit his lip—he had enjoyed it too, more than he usually did.
He reached into his shirt pocket, and pulled out a business card, scribbling an address onto it. "I'm in town for the next few days. Come to my hotel." He handed the piece of cardstock to Ciel. "Security will let you in when you show them this."
Ciel stood up, feeling Sebastian's cum leaking from him. He grabbed a tissue, cleaning himself as best he could. He dressed and looked at Sebastian, unsure of what to say.
Sebastian smiled. "I'll be waiting for you." He turned and reached for the doorknob, but a hand on his arm pulled him back.
Ciel kissed Sebastian one last time before leaving.
