Sebastian kissed the boy hotly, pushing his tongue into his mouth without any hesitation. He collected Ciel's wrists and pinned them to the mattress above his head, loving the way the child squirmed and arched upwards. The demon pulled away after just a few moments, his free hand gently stroking Ciel's cheek. "What toys would you like to use tonight, baby?" He asked, voice low and soft, letting go of his wrists for the moment, instead running his hands up and down Ciel's sides slowly, the gloves rubbing against his skin almost tickling him.

"I want..." He fell silent for a moment, trying to think. They owned so many toys Ciel couldn't even imagine how many. He bit at his lower lip, knowing it aroused Sebastian further, resisting his urge to smirk victoriously as he heard a low purr of a growl escape the man above him. "The ears. And the tail. And the crop." His lips curled upwards in a delicious smile, taking Ciel's lip between his teeth and giving it a tug.

"Of course, kitten. Go get them." He moved off of the boy and instead sat on the edge of the boy, watching as Ciel, nearly naked, besides his shorts and stockings, climbed off the high bed, going to the little chest beside his wardrobe, where all of the toys Sebastian had bought or produced in some way were stored. The boy stuck his little backside in the air as he rummaged through the chest, and Sebastian bit his tongue and clenched his hands to fists to keep himself in place. Ciel came back, furry ears and a tail, one end of it being smooth glass, along with riding crop, the braided leather swinging as he walked. He clambered onto Sebastian's lap, looking up at him innocently as he situated the headband with ears atop his head, mewling for the demon.

"Such a good little kitty, you are," he cooed, taking the toy and whip and setting them aside. He was quick to remove Ciel's shorts, throwing them carelessly onto the floor. "Do you want Daddy to use his tie to blindfold you or tie your wrists together?"

The boy remained silent. He knew Sebastian's game, and he knew the man would punish him if he spoke without being given permission first.

Sebastian chuckled, kissing the boy's brow. "You may speak."

Ciel began to nuzzle against Sebastian sweetly, big eyes sliding closed, little hands holding to the front of his pressed uniform. "I want to tie my wrists together, because I like to watch my Daddy fuck me," he whispered, voice sweet and quiet and almost so innocent that the demon wanted to flip him over and just fuck him now.

"Of course, my sweet boy." He removed his tie and gathered Ciel's wrists once more, pinning them behind his back, before tying them together in a tight knot. Wordlessly, he pushed two fingers into the child's mouth, eyes taking on a light glow as he felt him suckle and swirl his tongue. Sebastian pulled the fingers out of his sinful little mouth and trailed the saliva-coated tips down the knobs of his spine, before rubbing one against his hole lightly, pressing kisses to his shoulder.

He did nothing but rub, gently pushing but not with enough pressure to actually enter him, until he felt Ciel pull at the front of his waistcoat, looking up at him with wide, pleading eyes. He couldn't speak, so he just mewled in want, hips rolling downwards. Sebastian chuckled unable to resist him any longer, slowly sliding in his finger to the knuckle. He relished in the way Ciel clenched around him and rolled his hips, already impatient and wanting more.

Ciel let out a whimper. He wrapped his arms around Sebastian's neck, resting his forehead against the demon's shoulder. He closed his eyes and forced himself to just appreciate what's in him right now, trying his best to not think about the cock rubbing against his inner thigh and how tiny this one finger is compared to that.

When Sebastian slid in a second finger, he moaned in appreciation, keeping himself nice and relaxed. The glass end of the tail pressed against Ciel's swollen lips and he was eager to take it in his mouth, picking his head up so he could look up at his demon while he suckled on the tail, pretending it was Sebastian's cock. He heard the demon growl lowly and felt his cheeks heat up a bit, though it only encouraged him to take more into his mouth, hollowing his cheeks out. The tail was soon pulled from his mouth and the almost satisfying fingers were pulled from his hole.

The now dripping and warm glassy end of the tail rubbed against Ciel's entrance, teasing him for a moment before slowly pushing in. His nails dug into Sebastian's shoulders and he mewled, afraid he'd call for the demon if he did anything but. Ciel waited until the tail was fully in before beginning to squirm, the burn of the stretch slowly fading.

"You know what to do now, don't you, kitten?" He breathed out, hands settling on Ciel's hips and slowly easing him to the ground.

Sebastian decided to make it easy for the child, unzipping and unbuttoning his trousers, removing them for Ciel. The child scooted closer, nestled between the demon's legs, looking up at him. He watched as Sebastian slowly removed his tailcoat and waist coat, unbuttoning his shirt but simply letting it hang from his sides instead of removing it. He took the head of his cock in his mouth, closing his eyes as he tucked his teeth away and rubbed his tongue against the slit, eager to taste any precome that there was. He took more of the length in his mouth, having to slack his jaw to fit it in.

One of Sebastian's hands came up to slowly stroke his hair, careful of the headband. He rolled his hips upwards and Ciel gagged and Sebastian growled, both the sound and the feeling arousing him beyond belief. He gave his hair a gentle tug, urging Ciel to pull off before he hurt his throat.

The boy did as he was supposed to, and he settled for nibbling and lapping at the base of his cock, causing the demon to groan softly, back arching just a bit. Sebastian reached downwards with one hand, tweaking one of his nipples. He rolled it between his thumb and index finger before giving it a little tug. The feeling made Ciel squeak and moan against the length, the soft vibration making Sebastian shudder in pleasure. "You're such a good little kitten for Daddy, aren't you?" He purred, voice completely breathless.

The boy opened his eyes and stared up at him, dragging his tongue up the underside of his cock before taking the head in his mouth once more, hollowing his cheeks suddenly, suckling harshly.

The demon outright moaned then, loud and lewd and utterly shameless. His head hung back, soft throat and neck exposed, and Ciel wanted nothing more than to mark it up until there was no white space left behind. Sebastian, despite the nearly overwhelming pleasure he felt in that moment, pulled the boy off, and instead positioned him on the bed, on his chest and knees.

He wrapped a hand around where the fur and glass meet, beginning to twist and move the toy inside of him slowly, pressing kisses to the backs of Ciel's thighs. The boy squirmed and bit onto the bedspread, the feeling hurrying him to orgasm quicker than he expected, and he came with a muffled cry, release dripping onto the covers.

"What a bad boy," he murmured, though they both knew it was his intention originally to make the boy spend prematurely. "You came without Daddy's permission." He pulled the tail out as slowly as he could, wanting Ciel to feel as much pleasure as possible before he brought the crop out.

He set the toy aside, instead picking up the riding crop. He dragged the leather up Ciel's back, loving how his skin broke out in goosebumps and his hands, helplessly bound, clenched to fists. He set a hand on Ciel's backside, beginning to knead and rub the skin there gently, wanting the child as relaxed as he possibly could be, before he raised his left hand and brought the crop down against both buttocks, chuckling when the boy's back arched and he cried out, toes curling. The skin that was hit reddened and swelled just a bit, and Sebastian lightly ran one finger over the injury.

"Count," he ordered, without room to discuss otherwise, bringing the crop down three times in quick succession. The child called out the number each time he was struck, wishing his hands weren't bound so he could hold to the sheets. Sebastian set the crop down and turned Ciel over, smiling almost gently. "Are you going to behave now, kitten?"

"Yes, Daddy," he said quickly, risking the possibility of being punished for speaking when he was not allowed to, even if he was spoken to. "I promise I'll be Daddy's little kitten and I'll never ever be bad again, I promise!"

The demon chuckled and kissed the boy's brow, before turning him onto his chest and knees once more. "Good. Now, I expect you to come when I tell you to, and only then. Not a minute before and not a minute after. Do you understand me, kitten?" Part of his 'do you understand me' is an 'are you okay with this', and he isn't sure if Ciel understands that or not, but the boy is nodding eagerly and he nearly forgets about clarifying himself.

Wrapping a hand around the base of his cock to keep himself steady, Sebastian rubbed the head of his length against the boy's hole for a moment, before slowly pushing in, kissing the space between his shoulder blades. Even though he is impatient, he knows that the switch from a little toy to his actual cock is a big one, and that Ciel needs a moment to adjust and relax. So, he rubs his baby boy's hips gently, before wrapping his arms around his waist and pulling him up, Ciel's back pressed against Sebastian's chest, his bound hands pressing against the demon's stomach. Sebastian nibbled along the shell of his ear, feeling Ciel shudder. The boy gives a feeble nod after a few minutes and it takes all of Sebastian's will to not fuck his brains out. Instead, he begins to thrust shallowly, hardly moving in and out at all, until he is positive Ciel's body is ready for more. He picks the pace up a little bit, biting and kissing at his neck, growling lowly against his skin.

Ciel mewls and he wants desperately to speak, but he doesn't say a single word. He knows better, and the last thing he wants is a punishment when he is so close to getting exactly what he needs. His nails dig into the demon's lower stomach, hips rocking back mindlessly. He feels the demon's muscles tense and relax as he moves, and he wishes his arms were unbound so he could wrap himself around Sebastian, legs around his waist and arms around his shoulders and neck, feel Sebastian so hot and slick and close. But this position will do, and he lets himself be pushed back down into the bed.

Sebastian's hands fall to grip Ciel's hips, holding them tightly as he sped his thrusts up, and Ciel begins to let out load moans, the force of the demon's hips pushing the child forward each time he pushed in. He growled lowly in his throat as he felt Ciel tightening around him, a warning of an upcoming orgasm, trembles gently wracking his body. "Hold it in," he hissed, walls tightening around his cock further as Ciel tensed and struggled to hold it back. One hand let go of his hips, instead raising and smacking his ass, loving how the boy yelps in surprise, trembling turning to shaking now. "You may speak," he allows, voice low and rough.

"Oh, pl-please, Daddy," the child moans out, hips rolling back against Sebastian's desperately. "Please let me come, please... I'll do anything!" Ciel twists his wrists in his bindings, feeling the fabric dig into his skin and knowing it will leave a mark.

The begging wasn't the greatest he's heard, but he knows it's the best Ciel can do, so he gives him permission to orgasm, and groans as the boy shudders and quakes below him, crying out for him as he came again. Sebastian moved faster, lasting a few more minutes before he pulled out and came all over the boy's lower back and backside, letting his release drip into his slight gaping hole. He unties the boy and turns him over, pressing gentle kisses to Ciel's wrists, removing the cats ears.

"You were so very good," he praised, smoothing the child's sweaty hair from his eyes before going to run him a bath.
