Day 5 - Burning

"What if what it wants is for me to completely devour you?" Summary: Sylus is struck with a fever, however he’s far from ill. The aethercore inside his body is acting strangely, giving him an insatiable desire for all-consuming hunger, an ache he knows only your body could cure. He tried to keep you at a distance while it cooled off, but you insisted on popping up to give him his birthday gift. Now that you’re here, he just can’t resist.

“Okay boys that's enough.” you huff to a flustered set of twins. Luke and Kieran are determined not to let you in on their boss' very strict orders. They know the consequences of those who disobey him. It's a healthy fear, as the man himself admits, but if it's one thing they really hate, it's having to tell him they disobeyed you. It was cute of them to ignore your request to enter Sylus penthouse, now it was getting annoying.

“Please, Miss, he really doesn’t want any visitors tonight. You can always come back in a few days…” One of the masked twins pleads, and you’re too irritated to care which one. Did he just say a few days?

“You're still not giving me a reason why I can’t just-” You try to slip past them again but can’t, their large bodies stopping you in your tracks.

“Miss, he’s not feeling well.” the other chimes in. It’s even less convincing than his brother’s attempt. You scoff at them both again.

“Then why don’t I go and take care of him.” you say shortly.

They turn towards each other and then turn towards you. They look like they’re about to short circuit if you don’t walk away but you’re not giving up that easily. You’ve already gotten dressed in your sexiest lingerie, the red he loves. The thin silk of the red lace felt like a target on your skin. You knew the bell collar would drive him mad…the sound of his own possession ringing with every move you made. Nothing but lace and little straps he can tighten and pull to his liking. Being in complete control? His favorite. You put a long coat over it to go and surprise him at Onychinus Base, with the guise of cupcakes and being a sweet girlfriend. In all actuality you were perfectly intent on spending the evening playing with icing and giving him the striptease you practiced in the mirror. It was his birthday, after all. You wanted him to feel loved and adored, the way he made it his every mission to do for you.

Now you were standing at the doorway still trying to convince the twins to let you go through with your plan without being too blatantly obvious what you were there for. You ran a hand through your hair and looked at them sweetly.

“Just tell him, that I’m here, he isn’t answering the phone. Something has to be the matter. It’s his birthday.”

The twins look at each other once again, perplexed. Surely they hadn't forgotten. You hear one pull the other to the side and whisper something about risking their lives or not, and it gives you just enough space to slip by them and rush yourself through the door, pressing your palm to the coded entry. You slam the door behind you and let out a maniacal laugh when you hear the twins cry out in frustration. Muffled through the massive woodwork, but something like “He’s going to…” and “Yeah but she…” but you ignored it and stepped further into the large room.

Everything was dark, darker than usual. An uneasy feeling spread across the room but you tried not to be too concerned. He was usually brooding around his birthday. You always had to pull out all the stops to get him to celebrate.

“Sylus?” you call out, eager to see him, setting the cupcakes on the table.

No response, but you hear the shower running and follow the sound and smell of his candles and body wash. Intoxicating and pulling you towards him as you enter into his bedroom, the sheets disheveled and pillows thrown across the floor. You wonder briefly what happened, curiosity overcoming hesitation.

“Sy?” you peek through the bathroom door.

He’s leaning against the glass side-wall of the shower, the water rushing down his body, highlighting every curve of his muscular torso. He’s totally exposed from your angle in the doorway. Your body reacts immediately, unable to concentrate on anything but his arms, his lips the way his hands are dragging all over his body in desperate sweeps like he needs to be touched. Your thighs squeeze together in anticipation. He’s panting, a deep breath that looks feral, his cheeks and chest are flushed. You watch him for a moment, as he takes his hand and pulls at his thick and heavy length, which is now clear to be the object of his ire. He hisses at the touch of his own fingers, and you can’t help it. Your breath hitches.

“Sylus…” you embarrassingly catch his attention.

He sees you and turns off the shower, his eyes flash towards you, left eye beaming a bright red. He sighs heavily and wraps a towel around his hips, barely drying off at all. As he opens the shower door, he presses the intercom on the wall to call for the twins.

“Idiots.” he says. He doesn’t wait for a reply, he just turns to you quickly, his body still tinted red with heat. “You aren’t supposed to be here, kitten.”

He’s stepping towards you, large frame moving over to hover over your face, but his brow is furrowed, almost upset.

“Why didn’t you want me here…” you say, somewhat hurt, but more intrigued than anything.

“It’s not a good time for me, I don’t think you should stay.” he lowers his head and begins to walk towards the chair next to the floor to ceiling window in his bedroom. He sits down and covers himself immediately with a pillow, something you find extremely odd, as he’s always stripping down naked in front of you unexpectedly. During dinner, while you garden. First it was to fluster you, but now it’s just any time he feels the need to be closer to you.

“Sylus what are you talking about? Do you really think I’m going to let you spend your birthday alone? And why are you covering yourself like that?”

He ignores the last line of questioning and a look of confusion spreads across his face. He shifts in his seat and hisses again, the same way he did in the shower, you step towards him and he looks at you with a glazed over haze in his eyes.

“It’s my birthday?”

Your heart sinks into your chest.

“Yes, my love. I brought you cupcakes.” You nod your head toward the kitchen. He puts his hands in his face and sighs heavily again. You take the opportunity to slide down to the floor in front of his chair, knees on the plush carpet, in between his legs. The pillow blocking everything you had been so excited to see moments ago.

He looks at you with primal intensity, his left eye still flame red, his chest heaving slightly, trying to calm his breath. He’s inhaling your scent, rolling his eyes back in his head for a moment and returning to your gaze as you slide your hands up his toned calves, to his thighs. His skin is so hot he could combust.

“Please, Sy. Tell me what’s wrong. Are you feeling sick?”

“You’re so sweet, kitten, thank you for the cupcakes.”

“I’m not letting you up until you tell me.” you whisper and lean against the throw pillow he’s holding to his midsection. He groans deeply.

“Nghh. Fine… ah… it’s my aethercore. It’s reacting to something, or having a reaction I don’t fucking- ah… I’m sorry can you sit up please?” he looks down at the pillow now bulging underneath your touch.

“Oh you mean… IT it.” You smile at him deviously.

“It’s not funny, kitten. I’m in pain. I can’t think straight. I feel like my skin is on fire. I want to- ah, I want to…” he throws his face into his hand again and runs his fingers through his hair.

“Why wouldn’t you tell me? I can help you.” you lean forward, careful of his sensitivity, and kiss him on the cheek.

“No, my love, ah…shit. That’s why I told them not to let you in. It’s deviant. It’s making me fucking ravenous, I don’t want to hurt you. If you stay… I won’t be able to hold myself back. Normally it wants me to destroy things, I can suppress it, only destroy what's necessary. But now-mmm, now… it wants you.”

The though of Sylus in heat like a predator needing to find his mate, unable to hold back an insatiable need to fuck you so hard it leaves you in pain the next day is everything you needed tonight and more. You decide this is the only way to cure him, and you happened to plan his birthday present out with ideal timing. What could be better?

“Sylus, you won’t hurt me. I want to help you… please let me…” you stand and take a few steps back. You let your coat fall down to the wayside and pool on the floor at your feet. Your figure is accentuated by the thin red lace and bodice of the lingerie, the little bell collar attached to a long silk tie.

“Kitten… you don’t know what you’re doing.”

You walk over towards the bed, he’s gripping onto the pillow with every ounce of strength in his body as your hips sway back and forth, and you place yourself delicately on the soft sheets.

“If it’s me that it wants, I’m right here.” you say, watching him and rolling onto your stomach, laying at the end of the bed.

“What if what it wants is for me to degrade you, consume you, ruin you?” his voice is so low it's slipped into a register you barely recognize. You say nothing, but continue to stare at him. He begins to stand.

“I want you to ruin me, then.” you say with resolve.

“Careful what you wish for, sweetie.” A smile is playing on his lips, barely there. He tosses the pillow aside and drops the towel down at the foot of the chair. His heavy cock springs free, already leaking at the tip and angrily red from the friction and lack of release. Why does it look… bigger? How is that possible? The amount of foreplay needed to make you ready for him was already more than you typically bargained for, but tonight you couldn’t imagine that fitting anywhere. Your body shivers with want and a hint of alarm.

“Sy…” you whimper, but he’s already moving towards you like a panther moves in for it’s kill. Sleek and cunning. Before you can protest any further, your mouth is being completely enveloped with him. He’s pushing past your tongue and hitting the back of your throat almost immediately. You relax and take him in but your eyes spring tears in their corners that threaten to fall from the shock and stretch. You gag slightly.

“No no no, kitten. No going back now. You’ve already told me I could use you tonight. You're such a good girl for me. Just take what I give you.”

You relax your jaw further, and moan into his thrust as he pumps relentlessly into your mouth. Over and over, as his hands move toward the sides of your head to draw his long fingers through your hair and pull it up into a pony tail he’s holding with both fists, using it as leverage to get deeper. Drool is dripping down your neck, down his balls and onto his thighs, you’ve never felt him as hard, as urgent. Usually giving Sylus head results in him getting too close, not wanting to be anywhere but inside you, and deciding he wants to make you come a few times before he fucks you.

Tonight, however, he’s using you. Truly using you. When he said degrading, you didn’t quite know what he was describing, but if this was it, you could get used to it. The way he pressed into you, the look on his face as you looked at him with your tongue out wide, taking him as deep as you could without gagging again. Without much warning except the force of his hips becoming sloppy, his breath was short and grunts were louder, the release he was so desperate for was now suddenly filling your mouth. Hot, savory, and so so much. You try to swallow it all but a small dribble falls down your chin from around his huge length, pulsing into you as he holds his grip steady on your hair.

“You did so well, baby.” He groaned and pulled himself out with a satisfactory *pop*. His thumb and index finger praised your mouth as he gathered the remains of his release and pushed it into your mouth with his finger. “We're not wasting a single drop tonight.”

He wasn't done. Of course he wasn't done. He would never get his fill and leave you unsatisfied and wanting, not to mention his cock was still rock hard. You get the feeling you may have not understood the extent of his aethercore reaction, but you can't resist finding out what else it wants from you. What else it's telling him to do to you, and how much he'll give in.

At first you think he's going to devour you fully, next, but he's already pushed himself beyond his normal bounds. He needs release, he needs to feel himself deep inside all your holes, he needs to fill you again and again. The need is so strong it terrifies him but you just feel so... Fucking. Good.

Suddenly his evol is lifting you, cunt already drenched and waiting without his tongues’ usual torture, into the air and onto your back on the bed. He lowers himself over you and in between your thighs. The length and heat of him pressing at your entrance. He looked at you with a keen sense of longing and desperation, but his movements were feral. His eyes told you he'd soon be begging to sheath himself inside you if you didn’t pull him in fast enough.

"Open up for me, sweetie.” he commands roughly.

You wrap your arms and open your legs wide as he sinks into you, slowly, deliberately. The thick head of his cock brushing against your cervix, kissing the spot deep inside of you. He can’t stop, not now. He has to have more of you. He moves his hands underneath the curve of your ass and lifts your hips to a punishing angle. His breathy growls and moans ring out in the room over the sounds of your whines, trying your best to accommodate his size when he’s in heat like this, trying to withstand the weight of his lower body, slamming you into the headboard. Your breasts bouncing with every powerful snap of his hips into you, he takes one in his mouth and sucks a dozen little love bites into one and then the other, never breaking the pace of his thrusts. You’re in heaven, bliss overcoming the lewd sounds coming from your center as you get so deliciously wet for him, slickness running down your thighs, leaving a thick ring of your desire around the base of his throbbing member, the weight of his sac slamming into your ass. He watches it disappear inside you again and again, savoring the sound of the bell on your neck ringing against his chest.

“Yes, that’s my perfect girl. Taking my cock like you were made for it. You’re letting me get so deep - fuck.” his words sing down your spine and take root deep in your belly, your orgasm building quickly.

“Is my little kitten gonna come for me?”

“Yes-shit Sy…” you cry out.

“Squeezing me so tight… you think I won’t push right past those little walls and hit your spot over…and over again?” he says, punctuating his words with his thrusts. It sends you over the edge. The sound of his voice, the way he’s hitting every perfect angle. Deep in a mating press, like an untamed dragon breeding his lover, all consuming.

"I’m gonna… oh fuck-please let me come, daddy.”

The pet-name draws out a deep and unhinged growl from his chest, low and animalistic. He pounds into you again.

“Go ahead, my love. Make a mess on me, I want it all.”

You come undone around him, walls fluttering and legs shaking, unable to withstand the waves of pleasure crashing over you. It’s enough to send him once more past the edge himself, spilling inside you, pouring himself as deep as he can possibly go. It’s much more than usual, even after he’s already been spent, you’re full to the brim, dripping out onto the bed and around him. His face is still flushed, eyes still glowing red and cock still hard and greedy as ever.

"Oh kitten, tapping out already when I haven’t even used your new leash. Be a good girl for me… Turn over.”

Happy birthday to Barbara Hale (April 18, 1922 – January 26, 2017).
