a/n: I’m on Love & Deepspace fic tumblr! 😮 hope I’ll be welcomed nicely here haha. As a peace offering, this is my present to everyone (and especially the Sylus girlies)!

You shift your body slightly, trying to make yourself comfortable, on top of taking slow breaths, your heart fluttering at Sylus's soft voice coaxing you. 

"That's it. Take it slowly, kitten", his voice slow and deep in your ears. But you don't see the way he's shutting his eyes and biting his inner cheek every time you squeeze around him. He's trying to pace his breathing as well, but it feels so fucking good.

You whine softly against his bare chest, his heat radiating off you, his slender fingers stroking your hair slowly, and his other hand drawing soothing circles on your thighs. 

You don’t remember how it started, but your thoughts start to drift, recalling the times your mind would float whenever Sylus had his lips on yours with you straddling on his thick thighs. He would devour you, painfully slowly because he knows that’s what riles you up, and he definitely enjoys listening to your whimpers, your non-verbal pleas for him to do more to you. He’d make sure your lips are wet and messy once he’s done with you, his touches teasing and light against your skin. Sylus secretly wants you to beg for it, because he knows that he’d give in to you in a heartbeat. His fingers would cup yours that were on his chest, and the look he would give you reset all the butterflies in your stomach. You would feel his thick erection, hidden under the thin silk black bathrobe he’d always wear against your clothed pussy, and dear god, he’s so fucking big. But before you could ask, Sylus would trail his fingers to tease your wet clit and pussy, soaking in your adorable reactions he swears is enough to get him off, erasing the question of wanting him to fuck you off your brain when the pleasure from his fingers tingles through your body. 

Sylus doesn’t pride himself as a generous being, but he thinks he’s always generous enough for you. He realises he enjoys having his face in between your legs, making you squirm, listening to you sob when he overstimulates you with his tongue, making sure his tongue presses and grazes fully on your clit while he listens to you fall apart, his crimson eyes locked onto you while he holds you down to take whatever he’s giving you. 

He’s good at distracting you like that whenever you want to bring up the question of fucking. 

This time though? Through your wet lashes from the overstimulation and hazy thoughts, all you were craving for was just to be fucked stupid by Sylus. Your hand reached out and pushed against his head. Sylus pulled back slightly, confused for a moment. 

“What is it, sweetie?” He paused, his hands trailing up and down your thighs. 

Your mind slowly clears, but your pussy is still pulsing from him tongue fucking you.

“Need you to fuck me, Sylus. Please. I don’t think I can take it any longer.”

Sylus is momentarily taken aback by your demand, but he realises he can’t keep holding it off, mostly because there’s only so much longer he’s able to hold back, especially when you’re begging for him like that. 

“I don’t think-“

“I can take it”, you muttered stubbornly, yanking your partner towards you. You shift yourself above him, straddling his thighs, just shy of his appendage. 

As much as your determination is endearing, Sylus knows your comfort should come first. And he knows very well that his cock isn’t gonna fit into you in one go, so he decides to let you gauge it for yourself—putting your hands into the string of his robe, gesturing you to loosen it. 

And you do, your gaze flickering from his cool expression to his silk robe sliding off his body when you untie the string. 

You swallow hard when his cock comes into view—thick, long and heavy, the tip red with a wet sheen of precum. Yeah, that’s definitely not gonna fit in you in one go. You and him solely being just wet enough wasn’t going to cut it. 

Nonetheless, you’re still determined. Your eyes meet his gaze and an idea pops into his head. 

He intertwines his fingers with yours.

“Tell you what, sweetie. I’ll fit into you slowly. Doesn’t matter how much you can take, I just want to make sure you’re comfortable when you’re doing so.”

“But-“

He presses his lips on the back of your hand. 

“I’ll be fine. You trust me, right?”

You nod, watching the way his eyes soften before you. 

So there you are, lying on your side, facing Sylus, your cunt trying to adjust to his cock as he stretches you open. It’s been a couple of days since you’ve been size training with your partner. It started off with getting his cockhead in, and that was already making you hitch your breath. Then inch by inch he sinks into you from then. He’d let you cock warm him like that and it never failed to leave you so full one session after the next. 

It’d been seven days, and you barely pushed through three-quarters of his girth. Initially, Sylus still could tease you while you tried to take his cock, but as he sunk deeper into you after each session, it started getting harder for him to maintain his composure—every twitch, every squeeze—had him digging his fingers into his palm, clenching against his silk pillow and breathing a little harder. 

He huffs once more when he feels you clench around his cock. 

“If you’re gonna keep clenching around me like that, Kitten, I don’t think I’ll be able to handle it.”

You glance up, watching the way Sylus’s platinum hair becoming a tousled mess against the pillow. His crimson eyes cast to meet yours, his lips pulled into a slight frown. 

“I can’t help it”, you reply, suddenly feeling self-conscious. 

You hear Sylus hiss slightly once more when he twitches inside you. 

“Do you think you could fit another inch in?” It almost comes off as a beg. 

You inhale shakily, shifting yourself further downwards, taking another inch of his cock. The both of you gasp at the sensation. 

You freeze at the thickness. How far down are you already?

“You’re almost all the way in, Kitten”, Sylus whispers, almost as if he heard your thoughts. His breathing is growing heavier by the second, and he’s forcing himself to hold back from just thrusting the remainder of his cock in. It’s dangling over him like his favourite prey. 

His thumb strokes against yours, trying to distract you from the pressure on top of pressing your forehead with kisses, singing you soft praises.

Your mind is gradually turning more hazy with Sylus’s cock taking up the majority of your thoughts, on top of his body soap that’s been creeping into your olfactory senses. The more Sylus inches his cock into you, the more he’s pressing onto your g-spot, and the more it’s starting to make you see stars whenever you blink. You’re growing so sensitive that you’re feeling every throb Sylus’s cock is giving you. 

Your hand is on his arm, trying to ground yourself from the slight soreness. Another strained whimper when Sylus pushes him deeper into your pussy. Slick leaks from your pussy and it doesn’t go unnoticed by Sylus. 

Another kiss to your temple, another circle drawing session on your thigh.

“Do you want me to go all the way in?” 

Your toes curl.

“I can take it.”

So Sylus inches his cock right to the hilt, knocking the wind out of you. 

Tears are prickling at the corner of your eyes, but oh god you do feel so good. 

“How are you feeling, sweetie?”

You hiccup softly. “So full.”

He chuckles. “Such a good girl.” The vibrations of his light laughter only press his tip further onto your g-spot, and it’s making your thighs shake from the impending orgasm. 

“D-don’t move so much, Sylus. You’re gonna make me—“ you try to bury your head into his chest but he stops you with his fingers in your chin. 

“Make you what?” 

He intentionally shifts, and his cockhead hits your sensitive spots again, sending fireworks into your eyelids, and a strained moan. Sylus seems to enjoy your reactions, because then he flips you to your back, his large frame looming over you, forcing you to look up at him with your legs folded, and still with his cock in you. 

Oh no. 

Sylus looks down at you with the faintest glint of softness in his eyes before it completely disappears, now just hunger seeping through the red. 

“Sylus!-“ you gasp, his fullness penetrating into you again, this time easily, considering the wet and sopping mess you’ve made around his cock. 

He only hums in reply, then pulling out slightly before he pushes into you again. He’s found your sweet spots, and he’s not letting it go that easily. 

The knot in your stomach pulls tight, and it’s making you tear up in sheer pleasure. You’re barely able to meet Sylus’s eyes, not when he’s fucking into you and has your head thrown back while you’re fighting to keep your eyelids open. 

It builds and builds. Sylus probably realises it from how much you’re just pulsing on his cock. His thumb rests at the corner of your lips and you let him slip in, your glazed out eyes meeting his. It makes his heart flutter when you’re completely undone like this for him, but he’ll never admit it, at least, not yet. 

“Gonna cum. Fuck, it’s so much, Sylus-“ you whimper before your mind completely melts away. 

“Release all you want on me, sweetie. That’s my good girl.”

That’s enough to send you over the edge—your orgasm hitting you like waves, tingling through your body like electricity, the pleasure eating you up over and over again. Sylus watches affectionately while you fall apart on his cock—the way you’re writhing and squirming, the way his name leaves your lips after every moan, the way your pussy creams so much on his cock. He thinks he’s doomed because he never gonna get enough. 

“Looks like a little kitten made a mess”, Sylus teases. He watches the way cream pools at the base of his cock when he pulls out slightly, only to thrust back into you again. His eyes flutter shut at the tight warmth eating him up, groans replacing his words. 

“Now, can I make a mess in you?” 

Your watery eyes meet his, and he’s equally about to lose all composure. You cup his cheeks, taking him by surprise, before giving him a quick peck on the corner of his lips, and then you nod. Said corner of his lips lift in satisfaction at your approval.

He’s just ready to ruin you. 

His strokes become more heavy, the overstimulation shutting your brain off. Nothing but pleasure is surging through your nerves now. You’re even holding up your legs so Sylus can fuck you deeper. 

“Now be a good girl and take all of it”, he mutters huskily, burying his face against the crook of your neck, his eyes snapped shut and his eyebrows furrowed. 

Despite the fact that you don’t get to see the way Sylus’s face contorts in pleasure when his orgasm hits him, his groans right in your ears serve you satisfied for now while thick white spurts into your abused pussy, filling you up all the way, some seeping past your plugged hole. 

You don’t realise how much you’ve clawed down Sylus’s back while he was emptying himself into you. 

Well, he doesn’t need to know anyway. 

Sylus stays above you for a moment, the both of you catching your breaths. He still has the energy to plant more bites on your neck while you stroke his hair. 

He pulls back to look at your face properly, and all you can think of is how fucking good he looks post-fuck—messy, sweaty, and so fucking delicious-looking. His fingers brush away your strands of hair, and his thumb caresses your bottom lip. 

“You’re truly gonna be the death of me, sweetie.”
