It must’ve started somewhere with Sebastian asking you what you were thinking and you telling him about how deliciously good his knuckles feel like, whenever they pull out and push back in.

And it continued with the thought of how beautiful his fingers would look like with a coat of arousal on them.

Now, Sebastian’s deep brown eyes were staring at you.

You were looking back, already panting from coming so hard - the second time…right after your first one, cause he just didn't stop fingering you.

And then he opened his mouth, licking his fingers real slow and keeping eye contact with you.

"Mhh...you taste so fucking good, love", he mused quietly with a smirk, seeing how this simple gesture just made more arousal drip out of you.

He drags his long, thick fingers across the wet folds, basking in the way your legs twitch from the overstimulation.

Now with coated fingers again, he moves atop of you, letting his index and middle finger trail over your lips.

"Open, love. Taste yourself. You need to know how good this pussy is for me."

You gasped at his words, but faltered immediately, your tongue darted out to lick your own slick off his fingers.

It's salty, yet sweet. And arousing all the same.

Sebastian couldn't hold back his groan, feeling and watching your tongue swirl around his two fingers. You looked so pretty like this.

It reminded him of how, just a few moments ago, the exact same tongue swirled over the tip of his cock. Oh, it twitched eagerly between his legs at the image in his head.

He wanted you all to himself.

He wanted to show you every single way that would seek out this delicious pleasure.

He wanted you screaming his name, so the whole world would know, who you belong to.

You were his and only his.

"Good girl," he praised in a low voice, a dark and wicked grin forming on his lips at the plan forming in his head.

You were in for a wild ride.

His long and wet fingers pushed your lower lip down, making it bounce back up, when his fingers trailed further - down your chin and slowly to your neck.

"You are so fucking gorgeous, love. You have no idea," Sebastian whispered hungrily, his lips ghosting yours.

He closed the gap, his lips molding right into yours, as if they were made for each other. It didn't take long for his tongue to tangle yours into a dance of dominance, but at last all you could do was submit to him, letting him guide you to paradise.

Especially as his large hand gently grabbed your throat...but he added no pressure to your disappointment.

The Slytherin only smirked against your lips, knowing exactly how he played with you. He brushed his fingers across your neck, lips parting again and eyes travelling down.

"Hm, I do have an idea how to make you even prettier."

Before you could react, air rushed out of your lungs from the way he started sucking on a sensitive spot on your neck, skin darkening into a beautiful shade of purple.

"Sebastian," you breathed weakly, feeling the tip of his dick brush against your swollen clit, making your hips buck up.

"Keep moaning my name, while I claim you as mine, love."

You whined, when Sebastian moved less than an inch lower to place a second hickey on your neck, right next to the other one, cause it made him move away from where you needed him most.

He simply chuckled, when he felt you wiggle closer to him again and heard you whimper when his tip teasingly slid through your arousal.

"So needy," the brunette whispered, his locks tickling your skin as he went to place yet another hot kiss to your throat.

"Come on, moan my name."

Holding his weight up with one arm on the mattress, his free hand slithered up to cup your breast, kneading it, before flicking his thumb over the perked nub, teasing that sweet moan of his name out of you.

"Sebastian~"

You arched into him, shutting your eyes tightly and feeling like every inch of your skin was on fire - especially from the way his lips trailed lower, adding one hickey after the other.

It almost felt like his movements were calculated and intentionally slowly forming a symbol on your neck.

"What are you doing?" You choked, your mind getting dizzy from the attention the Slytherin gave you.

"I'm just making sure," Sebastian started off, moving back up to meet your eye, his voice low and dripping with desire, "everyone truly knows, who you belong to, love."

You barely heard his words, as his cock teased you right at your entrance and you took the opportunity to move lower, his tip slipping right into you, earning a threatening groan from the man above you.

You saw him struggle to pull out again, intoxicated by the feel of your warm and soft walls enveloping him, but he did so anyways, now looking at you with a dangerous glint in his dark brown eyes.

"Someone's eager, hm?" He whispered, the hand that was just teasing your nipple, now moving back up, to wrap around your throat again, this time adding a bit of pressure to it.

You were about to lose your fucking mind, you just wanted him to grab you tightly and fuck into you, making you topple over the edge in no time. You knew he could do it. He was that good.

But today seemed like Sebastian would pull everything from his bag of tricks to make you squirm beneath him.

He leaned down right to your ear, his hot breath tickling you.

"You've been such a good little slut for me, you'll be able to wait for me to fill you up just a moment longer, won't you? I need to finish this."

At this point, with his hand slowly adding more and more pressure, he could ask you anything - really anything - and you would agree in a heartbeat, if it meant he would finally fuck you into the mattress.

"Yes! Yes, I'll be good," you answered a bit too eagerly.

"Let's make sure, you can keep this promise."

Suddenly he held up all his weight through the hand on your neck and you were sure you'd either lose consciousness in the next second or combust - maybe both - while his other hand grabbed his wand off the nightstand.

You didn't even notice it, until you heard him whisper a spell.

"Incarcerous."

Thick velvety ropes wrapped around your wrists and yanked them above your head, the ends of it tightly knotted to the bedposts.

You yelped in surprise, ripped from whatever fantasy your mind just conjured and you looked up at your bonded wrists and back at the man above you, who has removed his hand from you and wore the smuggest grin on his lips.

His long fingers brushed over your sensitive skin, following the purple trail he started forming on your neck and collar bone. And he let his fingers tell you where his mouth would go next, so you knew exactly what he was doing.

Sebastian, possessive as always, was forming a big "S" out of hickeys on your neck and chest.

"You're insufferable," you joked and managed to roll your eyes at him with a smile, but when he only replied...

"And you're all that I desire."

...you almost lost it, moaning loudly with his teeth sinking into the soft flesh of your chest.

"You look so beautiful like this," Sebastian whispered hungrily against your skin, his full-blown pupils looking up at you through his long lashes.

Your hands gripped the velvet ropes tightly, needing to touch him so badly right now. Needing to feel his soft hair between your fingers. Needing to scratch his back until the red streaks would threaten to start bleeding.

Or he threatened you with his hand on your throat again, to not scratch him like that.

Sebastian complained at least a week for not being able to sleep on his back from your marks, though you know he prefers to sleep on his stomach anyways.

You were pulled right out of your thoughts, when his teeth sunk into your skin once more and you gasped.

"Still with me?"

Sebastian chuckled darkly, the glint in his eyes more dangerous than you've ever seen before. He was at his height of possessiveness.

He needed you here in this moment every second of the way.

This was...special after all.

"Yes...yes fuck. I just," you started breathlessly, his tongue gently licking over the seventh or eighth hickey. You lost count.

"Hm?" He simply hummed with a smirk.

"I want to touch you, please. I need to feel more of you. Please, Sebastian."

Oh, you begged so beautifully. It must've been his favorite sound.

Hm, no, there was one that exceeded this, yes, and soon he would hear it again.

His heart clenched in his chest at the thought and his dick twitched once more, precum dripping onto your thigh, which you kept on wiggling, but only slightly, so he let it pass.

The groan rumbled deep in his chest and his face told you how much he was struggling to keep your hands from him. To keep your inviting heat from him.

You let a small victorious grin slip on your lips, but quickly hid it again, hoping he didn't see it.

But of course, the Slytherin caught it.

"You little minx. You think you can break me so easily? You think I fall for your tricks?"

Oh, his hand slithered back up to your throat and this time you probably looked like a deer caught in headlights, eyes wide and shakily breathing, when his long fingers wrapped around and started to squeeze slowly.

And when his knee moved upwards to meet your slick folds, you cried out.

"Sebastian!"

"Mh...bad girls like you deserve to be punished, don't you think?"

Before you could reply anything, his knee started moving and you stared up at the man above you, who simply smiled down with pure smugness.

With your head falling deeper into the pillow below, his knee worked you up, making you climb higher and higher to this place of pure ecstasy.

It was pure torture.

How good his hand felt wrapped around like a tight necklace and his knee rubbing your clit, your hole clenching around nothing. And your hands still aimlessly wiggling in their restrictions, needing something more to hold onto, instead of the fabric.

"Are you close, love?"

Sebastian's voice was low and his breath against your ear tickled you enough to send goosebumps down your whole body.

"Y-yes," you moaned, gasping for air, starting to see stars from all the sensations. "'m s...close..."

"Are you gonna cum?"

The knot deep in your abdomen started tightening so hard, it almost hurt.

"Yessss~"

"Good," Sebastian simply whispered.

You were right on the precipice of coming completely undone.

You tasted it right on the tip of your tongue.

You shut your eyes tightly and...just...a little bit...more...and...

...he removed his knee.

You mewled, feeling the promise of an orgasm slip right through your fingers, leaving you breathless and so fucking desperate.

He cooed you, caressing your cheek gently, as if he wasn't the one causing this.

"Hush, hush, love. As I said...bad girls like you deserve to be punished. So...will you be a good girl and follow my orders?"

In this very moment you knew you hated him. You hated him more than anything else.

But God, if you'd die this exact moment, you'd die a lucky woman.

"Yes."

"Good girl," Sebastian praised you, brushing the hair sticking to your forehead back and giving you a sweet and gentle kiss, before continuing his work on your chest.

And you kept your promise, staying as still as possible for him to create his little masterpiece right on your neckline, which was hard to do with his fingers travelling all over your body and his mouth sucking your skin just right.

Your heart was beating out of your chest, and you whined under him, barely able to keep your promise when he sucked another hickey on you.

"Fuck, every little sound you make goes straight down to my cock. You make me so fucking hard."

Oh, and he made you feel just how hard it made him, rubbing his cock so perfectly against your clit, only making you whine more desperately for him.

"Lucky for you, I am finally done with my work here," he grinned, trailing the purple skin with his finger once more, as if to seal it with this gesture.

You need a moment to register what his words meant, but when it hit you, it hit you like a train.

"You've been such a good girl and good girls get what they want. So, tell me...what do you want, my dear?"

"Oh please, I need you."

Yes, you sounded so desperate, and it was music to Sebastian's ears.

"I need to touch you a-and I need you to fuck me. Just please...I need you!"

"Fuck," the brunette growled above you, his face contorting and you looked down, seeing a hand wrapped around his dick, which was pulsating and dangerously red-tipped, pushing down on it to hold himself back.

"When you sound like this, I'm not going to last even before getting inside you, love."

You smiled brightly at him, almost beaming, knowing just how much on an effect you were having on him as well. He was throbbing with anticipation and desire and so were you, seeing him grab his wand once more and finally releasing you from your confines.

Your arms immediately wrapped around Sebastian's broad shoulders, pulling him real close, kissing him feverishly. He had barely time to place his hands next to you, so he wouldn't crash right into you.

But you didn't care.

You just kissed him with so much passion, your fingers finally able to tangle in his brown curls and the others digging into his freckled skin.

He simply moaned into your kiss, tongue delving into you, while his tip once again brushed against your clit.

That tore you away from his lips for a moment and Sebastian just smiled, propped up on his elbows, fingers brushing soothingly through your hair.

"Are you ready?"

The love and tenderness in his words, his smile and his oh so beautiful eyes...you just knew that not only you belonged to him, but his heart and soul - his entire being - it belonged to you and only you.

He was entirely yours and no one could ever change that.

"Yes," you smiled back, pulling him in for another quick kiss before he started to push inside you.

Even with all this preparation and the amount of arousal pooling between both of your legs, the sensation of him pushing into you still left you absolutely breathless.

Your moans when he bottomed out, mixed together into a wonderful harmony of passion.

Sebastian started to move slow, your eyes fixated on one another as both of you let yourselves fall into the pleasure you gave each other. His hips increased their speed, the sound of wet skin slapping against wet skin starting to fill the room.

At some point the bed started creaking, earning a small chuckle from both of you in between moans and gasps.

Sebastian angled himself up above you, your hands flat on his pecs, feeling the rapid heartbeat inside his chest. His hips kept on snapping in an increasing speed against you, the tip hitting even deeper inside you, brushing against that spot, which made you mewl once more.

"Fuck, fuck, fuck," the brunette muttered in between thrust, seemingly lost in the moment, his eyes shut tightly and his control slipping.

You knew he was close, and he tried his best to get that one last orgasm out of you, before he would let himself come undone.

"Sebastian," you managed to say, pulling his attention back to you.

His big brown eyes were wide and dark, desperate for you.

"I love you."

And there was this warm and loving expression again. Now his eyes almost looked amber in the dim light of your room.

With a hand on his neck, you pulled him back down to you, holding him close, while his hips didn't stop thrusting, now hitting even deeper and pounding against your sweet spot every time.

Your whole body trembled from this new position and there it was in reach again...your impeding climax.

Big arms wrapped around you tightly, holding you, steading you, keeping you completely safe.

"I love you, too."

His whispered words and a very powerful and precise thrust were all that it took for you to topple over the edge with a scream of pure ecstasy. Your walls convulsed around Sebastian, tightening in an almost death grip and all you could manage to say was, "Inside. Cum inside."

And so, he did after just two thrusts, cumming in spurts of hot white strings that coated your insides, filling you up completely.

Your trembling limbs stayed like this for a moment, Sebastian's hips only moving subtly, drawing out your orgasm as long as possible, before he got too sensitive and stopped moving all together, knowing how much you needed him to stay inside after such a strong orgasm.

To be honest...even if the slightest movement right now hurt him, Sebastian didn't want to break this bond you two had in this exact moment.

This was all he ever wished for.

All he ever needed.

Yes, if he only had you in his arms just like this for the rest of his life, he would die a lucky man.

After some time, your breathing came back to normal, your eyes weren't as hazy anymore and reality crept its way back into your minds.

Still holding him close and staying connected, you two turned around, so Sebastian was on his back and your body on top of his.

It fit right into his, as if you two were made for each other.

Oh, you were sure of it.

You two belong to each other...forever.

With this thought in mind, a tired smile on your lips and his fingers drawing soft circles on the small of your back, you were lulled into a deep slumber, feeling absolutely safe and sound.

The next morning, after a desperately needed shower...only together of course, you stood in front of the mirror, getting dressed, while Sebastian dried his hair with a towel, another one hanging around his hips, as he walked over to you.

You pouted slightly, looking at yourself in the mirror, your fingertips trailing over the purple S on your neckline, the jewelry on one of your finger shimmering in the morning sun.

"Wasn't the ring enough?"

"Of course not, love," Sebastian chuckled, wrapping his arms around your middle, placing his head in the crook of your neck, smiling as he inspected his work in the mirror.

"When I said, I wanted you to wear my name, I meant it metaphorically and literally."
