You could do a one-shot about how Sebastian would help us if we ask him to eliminate someone who hurt us before and then he ends up comforting us in our bed? And who knows, maybe a smut will follow? 🖤

I put so much effort into this One shot for everyone to enjoy. Hope you like it and feel free to ask for a request again~.

Warnings: A bit of angst and smut, that means sexual contact. And also...lots and lots, and plenty more of pure FLUFF!!!!!!!

                                      You're my everything

Finally, after a very long day of work, you sat over the edge of your and Sebastian's shared king-size bed. At this time, your beloved demon butler was preparing his master for his bedtime before he could excuse himself and retire for the rest of the night.

It was raining outside, fortunately, stormy weather accompanied by the sound of thunder and the sight of lighting wasn't disturbing to you at all. This kind of weather is very relaxing in your opinion to say the very least.

Just as you were about to start undressing so you could change into fresh nightclothes Sebastian set out for you, however, you stopped in your actions right there as memories that had been haunting you for years crossed your mind one right after the other just as fast as the lightning flashes appeared and disappeared through the windows of the room.

Your stepfather was one of the most horrible, cruel, and ruthless people you had ever met. A pathetic alcoholic shit who was taking advantage of your mother's money and her absence because of her job so he could freely insult and torture you endlessly just for the sake of his own sadistic and perverted entertainment. You could still feel the toxic pain from the whipping and lighting cigars against your skin as if it were happening right now. Most of the bruises, burn marks, and wounds had faded away due to the number of years that had passed since those awful memories had taken place. But some deep scratches remained over the skin of your back, a reminder of what you've been through and that you managed to escape and run away, being forced to leave your mother behind after multiple tries to convince you should forget everything that happened and make a new start without her.

The decision was one of the toughest ones you have ever taken so far but you also had to respect your mother's self-sacrifice and grant her wish for you to have a promising future ahead of you.

From then and after the guilt along with nightmares were making you unable to make peace with yourself and leave and accept completely the past. Sebastian was well aware, you told him everything right after he marked you as his own and you both became mates for eternity. After you've been informed of your mother's disease, your dedicated devil offered you his assistance to dispose of the person who was responsible for your trauma and current mental suffering, but you kindly refused because you didn't want to make yourself a murderer even if it wouldn't be you to do the dirty act, at least that's what you said to yourself.

Even if the knocking from the other side of the door was soft it made you jump a bit and let out a small yelp in surprise but you sigh out in relief when you saw Sebastian entering your shared bedroom.

"Darling, is everything alright?" Sebastian closed the door behind him and with slow steps made his way to you, his one and only beloved mate. You didn’t give him a response he knelt before you and took your hands to his own, squeezing them gently to send your body a bit of comfort. “Is it the thought of your mother’s death that troubles you again my dearest?” Of course, Sebastian knew already the answer to that question. He stood up straight and sat right beside you. He let out a deep sigh and gently placed you on his lap, his white-gloved hands cupped the side of your face to make you look up at him. Half-narrowed eyes were staring down at you tenderly while his thumb was stroking the soft of your cheeks as well. “My love, I simply cannot stand the sight of you suffering any longer. Your nightmares had become more often and far worse. Is there anything I can do to help you? All you have to do is just say the word and I will do anything in my power to solve your problems at any cost” His hand leaned your head to rest against his bare chest while giving your back soft-loving rubs in circle moves.

You did hesitate at first but knew better that enough was enough. You shall not suffer anymore, there’s only one way to make peace with yourself and let go of your past. “Sebastian, there is something you can do to help me if you want it that much” 

“Oh, and what that might be my little devil?” He smirked devilishly down at you. The mischief and sadistic desire seemed like a wild flame through his eyes that had turned into that bright fuchsia color tone of his.

“I hope it’s not too late to accept what you offered me a few months ago, for him to become eliminated by your own very hands. However I have one more request, I’d like you to also search the place that used to be my home. See if can find anything that belonged to my mother and bring it to me. Would that be too much trouble for you? I mean, you don’t have to grand my requests if you don’t want to, you know that very well-” You’ve been cut off once his lips joined your own in a passionate kiss.

He gave a slow lick to your bottom lip asking for the entrance to that lovely mouth of yours. Your tounges danced together with him obviously being the one in charge. “Mmmm~” Sebastian hummed in satisfaction as he broke the kiss between you and him. “I’ve told you once and I will say it again, any request of yours is a wish and any wish of yours is my command and desire to fulfill. You are my everything so the seals we share prove so” In the blink of an eye the butler has taken off both yours and his upper clothes, letting them fall to the carpet on a spot right beside the bed. Your cheeks had turned in a dark pink tone however you were still on your bra that prevented your chest from being exposed...for the moment. Sebastian took your hand and placed it in the middle of his chest where your shared seal was and with his free hand, he touched your seal that was laying upon the crock of your neck. “By the next morning, everything will be settled and you shall have your dear mother’s belongings brought to you without any failure. I promise you that, but for now...let us enjoy ourselves and have some quality time together. Would you like that kitten?” His hands made their way to your back with his slender yet skillful fingers ready to remove the fabric around your chest area.

You looked away in slight embarrassment. Oh god if you only knew how much this demon enjoys the utterly adorable blushing face of yours. “Yes, I’d like that very much” You finally confessed. You’ve been marked and had sex with Sebastian for almost a year so this won’t be your first time with him. Every time thought you couldn’t help but feel your cheeks burning and your heart filling up with desire for him.

“My darling mate~” With a swift move your breasts were completely exposed. Sebastian laid your body against the soft comfortable sheets and hovered over you with blushing cheeks and a lustful expression as well. “My everything, give me your tongue, aaah...” His voice purred as he attacked your mouth for a heated make-out session, then his face leaned down and began to give sweet smoochies all over your face. Your neck followed shortly after too. “How about a hickey or two~?” He didn’t wait for you to respond when his lips began to suck on many spots of your neck, avoiding leaving any mark on your seal, he wanted that part spotless.

You moaned in pleasure each time a hickey was panted upon your sweet soft flesh.

Sebastian kissed each lovebite and then focused on each one of your breasts. Licking in circles around your nipple while his free hand was playing with your other breast. “You’re so soft and delicate my darling love~” He cooed between the sound of our moans. He ran a thumb over each hardened nipple and with the other squeezed soft flesh once again.

Your moans became even louder when he took one of your hard pink nipples into his mouth and began to suck, lick and kiss it with so much care. Sebastian hollows his cheeks as his wet tongue runs over it until it's all red from all of his work, he then realizes it with a lewd popping sound.

“And now the other one~” He gave your other breast the same care, your legs gave out small kicks from the amount of pleasure Sebastian was giving you. His face lowered to your stomach. “Oh, would you look at that, I already reached down to your belly area, let me show you once more how much I love to treat you here, won’t you dear?” His hands held into yours with your fingers linking together.

“S-Sebastian!” You almost shouted when the devil began to kiss you all over your belly and sides. You squeezed into his hands tightly when you felt his lips leaving tiny kisses up and down your thighs just to tease you a bit.

He slowly removed the rest of your clothes and underwear. The devil chuckled to himself and licked his lips at the sight of your beautiful flower that was so close to his face. “Now then spread your legs kitten and give your Sebastian a good meal to feast upon” He let go of your hands and separated your thighs gently. His one palm pushed firmly down to the skin area where your vagina was while his other hand was brought underneath you and cupped your buttcheek. He blows cold air over your swollen pussy and lowers his mouth to your core.

“Bon appetit” His tongue gives a long slick lick up to your slit only to have it curl around your clit. You flinch out and let out a heavy moan as your body responds to your lover's actions. He continues working his mouth lapping on your sweet-delicious juices. “Delicious, flavor no one else can give me but you, my precious mate. You’re so generous giving out so much nectar for me to enjoy~” His other hand used to push down the skin under your belly now grabs your other buttcheek as well. Urging you steadily thrust into his mouth while he licks and kisses your clit. His tongue stings into your vagina’s hole and uses your butt to help your body thrust a bit faster. Your head leans back and your whole body trembles in pure pleasure until you finally reach the point to cum right into Sebastian’s mouth. “SEBASTIAAAAN!”

“Mmmm, my you’re so good~” Your lover manages to murmur with his mouth still full of your pussy, he sucks softly while shallowing with greed all the cum, not allowing even a drop to be wasted.

It’s a good thing your shared bedroom had the best soundproofing Sebastian could adjust to the room’s walls. You were unable to be seen either because the windows had tined glass protection. Only the best for you darling.

Finally, his mouth has been removed from your womanhood, he sat on both knees with his upper body slowly rising to get a better look at you. Half-lidden eyes looked down at your panting form in a loving manner. His hand reached out to caress some stray hair off your pretty face. His body hovered upon yours once again and pulled you in for a warm embrace. “Kitten, are you sure we can continue?” He whispered smoothly to your ear while having you wrapped up in his arms.

“Yes, I’d like you to show me more love. I really need it, I need you Sebastian” You explained calmly, you were a blushing mess yet here you were asking your lover to show you more of the adoration he feels for you and only you. Your hand uses the back of his head to pull his face closer to yours. Noses touching each other as your hot breathing sends warm-soft waves to each other faces.

He doesn’t break eye contact with you not even for a moment. “My love” The devil whispers happily and slowly joins his lips with yours. Still kissing you passionately his one arm moves down for his finger to smooth across the head of his cock giving it the necessary preparation while he stares at you with so much affection and adoration.

You were so lost in his eyes that you didn’t notice he put a slender-long finger in his mouth just for a few seconds to cover it with his hot slicking saliva. “Ahh!” You gasped when his wet finger entered suddenly your vagina hole.

Sebastian chuckled at your adorable reaction. “Oh my, you didn’t believe I would enter you without warming you up a little, now did you, my dear?” A whine escapes from your lips and Sebastian laughs softly in response, easing his finger inside you in and out with gentle thrusts as he curls it slowly.

His eyes closed and a genuine smile slowly appeared across his face while hearing your sweet moans and whines. “You’re so wet yet you remain too tight for me to enter without causing you any pain. I guess we have to work a little longer before I can get inside you. Meanwhile, I will enjoy pleasing you” Stronger orgasm washes all over you as you see lighting spots right above you. The demon pulls out his finger from you and the next thing you hear is the falling sound of his pants and shoes along with his belt being unbuckled. “I will be gentle to my little devil, like always” He commented softly before he attacked his mouth with yours while his dick is slowly sliding inch by inch inside you as you scratch his back and your whimpers get muffed by him kissing you endlessly.

Your vagina gets accustomed to the stretch of his dick rather quickly and that convinced Sebastian to finally start pushing himself in and out while groaning loudly.  Hot breaths hit your neck as he buries his face between it and your shoulder. Your legs wrap around his waist by instinct and push his spine as a request to thrust deeper inside you and so he does. Yours and his moans mixed well in harmony. Each thrust brought you closer to the edge until you couldn’t handle the amount of pleasure anymore that made you cum and your demon lover a few seconds later as had already pulled his dick out from you and let his it shoot the pure white sperm all over your stomach and breasts. “Oh my, how foolish of me to make such a mess on you~” He purred and let out a naughty chuckle. “Now now, come here you” Your demon whispered and took you in his arms with your head resting on his shoulder. “Let us take a bath together, shall we? You poor dear I exhausted you so much~” Sebastian purred sweetly and caressed the back of your head before he opened the extra door the room had that led to your bathroom.

In a matter of minutes, the demon placed himself into the tub filled with hot steamy water and fresh rose petals with you sitting on his lap with your back resting upon his bare chest. “Ahhh...~” He let out a pleasant sigh and wrapped his arms around your body. “Isn’t it better now kitten? After such a good sex session, we had now all the stress and tension escaped from you. And what better than a hot bath to give you the final relaxation you were lacking after such a hard day~?” He gave your forehead a long sweet kiss before he started washing your body with shampoo and water. “There you go, that’s a good girl... let everything go and relax in my care”

You let out a big yaw that made your demon chuckle to himself and give your mouth a bunch of tender smoochies to wake you up a little.

“Don’t sleep here my darling kitten it’s not proper for a lady like yourself to do so” Sebastian spoke in an amused tone while he washed off what remained from his white juice off your belly, chest, and pussy with careful moves.

“It’s your fault to make me feel that relaxed” You commented back in a rather sassy tone.

Sebastian couldn’t help but laugh at your sassiness and gift you with kisses all over your face. “Maybe you’re right. Now if you will, close your eyes for me” Once you did as he said his slender fingers began to rub through your hair. After the bath, he dressed both of you into your night clothes but excused himself for a moment and exited the bathroom before you.

“You may come out now my love” He called out for you after some minutes. You exited the bathroom and saw a freshly made bed with your favorite fluffy blankets and right beside the bed a wheeled table with your dinner meal. “Come here my mate” He led you over to the bed and laid you with your back facing the big fluffy pillows. After he fed you the delicious meal he had prepared he tucked you both under the warm-soft blankets. But this time he let himself lay upon you with his head over your chest. You hugged him as if you were hugging a child. “I love you so much my kitten” He kissed your lips softly. “Mmmm, my everything~” He kissed you some more and lay right beside you with your bodies facing each other. He used one hand to bury your head in his chest and watched as your breathing slowed down and fell asleep in your dedicated demon's arms.
