"Young master, it is time to wake—" Sebastian stopped when he entered the room, the scent hitting him like a brick wall, and found his master very much awake. He crossed his arms after closing the door, admiring the sight—Ciel on his hands and knees, his ass in the air, pumping his cock into his hand and fingering himself, reeking of omega desire. He turned his flushed face to Sebastian, but didn't stop pleasuring himself. "I see your first heat has arrived. Shall I lock the manor up and leave you with the omega servants?" Sebastian inquired, feeling his own cock harden at the smell of his young master. He needed to leave soon, or he would be ramming himself into the boy.

Ciel didn't answer, just continued to look at Sebastian with heavy lids, sitting up to crawl over to the edge of the bed and climb down, his night shirt soaked with sweat as he approached his butler.

"Young master…" Sebastian warned, his erection now clearly visible. "If I don't leave now—" He inhaled sharply when the young Earl touched his prick, rubbing it gently through his pants. "Young master—"

"Quiet," Ciel ordered. "Don't you dare move." He had a fairly good grip on himself despite being fraught with desire and hormones—that's Ciel Phantomhive for you.

Ciel knelt at his servant's feet, his nose barely reaching crotch-level. He unbuttoned his pants with shaking hands, reaching into Sebastian's underwear to pull out his dick. He smiled hazily when he saw it, hot and big and dripping with pre-cum.

Sebastian watched his master, bewildered that he would he think of touching him like that. He realized at this point that they were definitely going to have sex, but he didn't want his precious young master to disrespect himself so. "Young master, please allow me to—"

"I said shut up." Ciel growled, before licking up the side of Sebastian's member. Sebastian moaned at the touch of his wet little tongue, darting around his cock with inexperience. He shuddered every time Ciel's hot breath caressed him, letting small moans escape from between his fangs.

Having been alive for thousands of years and frequently taking form as a human alpha, Sebastian had learned how to control his urges, but with Ciel mouthing over his cock, he wasn't sure he could hold back.

"Does it feel good, Sebastian?" Ciel muttered, looking up at his butler through thick lashes.

"Yes, young master." Sebastian breathed, running his fingers through Ciel's hair to reveal his purple eye. He felt the seal of the contract flare, and quickly removed his gloves with his teeth to prevent the seal from burning them up.

"I love it when you do that," Ciel moaned. "When you take off your gloves like that. I want…" He took a deep breath. "I want you to touch me with your mouth like that."

Sebastian bent down to pick the boy up, tossing him gently on the bed. He ripped open Ciel's shirt, buttons flying across the room. Lowering his mouth to his nipples, Sebastian carefully took one into his mouth, lighting clamping onto it with his teeth and pulling upward. Ciel gasped, caressing Sebastian's head as he played with his small, sensitive chest. Sebastian straightened up over the boy and spread his legs. He was about to bury himself inside Ciel when he got an idea, and stopped.

"What are you waiting for?" Ciel panted. "Fuck me!"

"I don't know, I don't think you want it." Sebastian mused.

Ciel blinked. "What? Are you going to make me order you to—" He stopped abruptly when he realized what his servant sought to reduce him to. "You want me to beg?"

Sebastian shrugged playfully, acting like he was in control of himself when really he was hanging on by a thread. "I'm just not sure you're thinking clearly. My young master wouldn't dare give up his virginity to a mere butler."

"I don't care about that," Ciel grunted. "My virginity doesn't matter, only the promise of my virginity matters."

"You don't want to save yourself for your mate?"

"No, I don't care." He repeated.

"Well, what if I'm not in the mood to cater to your desires?"

Ciel frowned. "Don't forget your place, demon." His eyes drifted down to the throbbing cock inches away from his opening, and he bit his lip, clearly feeling the effects of his heat. When he tried to scoot closer and grab his butler, Sebastian pulled away, causing the boy to whine in frustration.

Sebastian leaned his face close to his young master's. "Beg."

Ciel growled. "Fuck me, now! I order you!"

Sebastian's grin faded—he couldn't disobey an order. He slammed himself into Ciel with inhuman speed and he gasped in pain. "I would've gone easy on you if you'd simply done as I said, young master…" Sebastian whispered, thrusting harshly. "But now, I think I shall fuck you until you faint, my lord." He hissed the words into Ciel's ear, delighting in the screams of pain and pleasure coming from the omega.

"W-wait—Ah!" Ciel started until he was silenced by Sebastian's mouth on his, roughly biting his lower lip and fucking him into submission. "Seb—!"

Sebastian snaked a hand over his mouth before he could finish—no talking meant no orders. He could hear Ciel's moaning as he pushed himself in and out roughly, and the obscene squishing noises from the slick drooling from Ciel's hole.

Sebastian felt Ciel tense up, and knew he was close to coming. He grasped Ciel's cock with the hand that was previously covering his mouth, and therefore most of his face, and jacked it furiously.

"Sebastian…" Ciel choked out a sob, and the older male looked up at the boy's face, streaked with tears.

Sebastian halted, letting go of the omega's penis and stroking his face affectionately. Ciel groaned in frustration, tears streaming down his cheeks. "Young master, are you alright?"

"U-ugh, why did you stop?" He sobbed. "I was almost there…" He looked at his throbbing member. "It hurts now!"

"Generally, crying is a sign to stop." Sebastian explained, suppressing a grin.

"No, that's not—it's just it—" Ciel looked into Sebastian's eyes. "It's amazing. It's like nothing I've ever felt before, I love it, I need it!" He threw his arms around Sebastian's neck, pulling himself up to kiss his butler fiercely. "Fuck me, Sebastian, please…" He begged.

Sebastian held the boy's hips gently, and started to drag himself out slowly, before pushing himself in even slower. He kissed the Earl passionately, cutting off his erotic moans and mewls. Ciel's nails dug into his back, the feeling of being fucked so thoroughly driving him mad. Sebastian's cock was pressing everywhere inside him, and was moving so delicately that he could feel it throb along with his hole.

His penis ached and he whined, trying to thrust against Sebastian's stomach. He needed to come. "Sebastian… Touch… Touch me… please, please, touch me!"

"Yes, my lord." Sebastian breathed, tenderly grasping his young master's prick and slowly pumping.

"F-faster… God, faster, please! Harder!"

Sebastian ignored him, keeping his pace slow and intense. He listened closely to Ciel's breathing, paid attention to his movements and twitches, and right when Ciel was about to climax, he squeezed on his head, making the omega screech delightfully as he came.

Sebastian waited patiently for him to regain his senses before continuing to fuck him, but this time he picked up his pace, pounding into him again and stroking his member fast and hard. His could feel his knot starting to form, and pushed in as far as he could before coming.

Ciel moaned sweetly, relief temporarily washing over him as he felt himself being filled by the alpha. He laid still while Sebastian spurted into him, grunting softly.

"Sebastian…" He moaned. "Oh, Sebastian… Do I belong to you now?"

"Yes, you're mine now." Sebastian growled possessively, nipping at Ciel's lip.
