Why not? (Rougher)

You bend your upper body down lower, sliding your chest across the ground, keeping your arse up and visible. You let a slutty, loud moan escape your lips, slowly rubbing the lubricant around the rim of your backdoor. Biting your lip, you make low, soft moaning sounds, slowly spreading your now glistening arsehole wider with deliberately low speed. Letting your arse spread wide, then releasing, contracting back to its normal shape, then doing it all again. You make sure to make your grunts and murmurs as sexy as possible- you want this demoness to wait patiently for her prize. It's already having an effect- you can see her shift impatiently, her hooves making soft, tell-tale clacking as she attempts to control herself.

You're taking your time with this one- turning around, making deep eye contact with Lilnessa, you slip a finger into your mouth, coat it in saliva, bringing it out dripping. Placing it into your arse, you make sure to give out a teasing whimper as you slide it in deep. Lilnessa appears impatient now, her hooves kicking softly, breathing deeply, her massively bulging cock at full attention. You imagine what it'd be like to have such giant balls... probably need release near constantly. Whatever, she can wait for a while, right? Giving her a bit of dirty talk, you ask her if she'd like to fill your slutty arse up to the brim, and slap both cheeks, giving another whorish moan whilst you do so.

Another lick of your fingers, plopping two into its warm chamber. You make sure to make another, deep whimper, a sound attempting to demonstrate how badly you want to get fucked. Your let your fingers exit, when the thunderous beating of hooves sparks your attention- looking back, you see Lilnessa- lust mad, eyes crazy, like a berserker in a trance, charging full pelt across the room.

Oh god, maybe you went too far? The now sex-crazed demon sprints, full speed, directly towards your upright butthole. You haven't even stretched it out significantly yet, and incoming is a manic, impossibly hung hellspawn. There isn't much time to consider consoling, or attempting escape- like a homing missile, the centaur aims her dickhead like a lance, resolved on release, and there's nothing you can do about it.

It happens in slow motion. The final few metres of sprint, the grinding of braking hooves, her feet skidding past you and out of vision. The momentum of a fully erect horsedick slams into your pucker- instantly, it's spread wide to accommodate the new found intruder. Your eyes wide, you grunt loudly at the extent of the pain, the head fully engulfed, with the exception of her thick rimmed flare. It presses against your arse, resisting for a moment, before your butt gives in to bulge around the added girth. With still relatively low resistance, given the **** behind it, the shaft begins- you feel the intensely bulbous texture, each nook, each bulging vein sparking your insides. It doesn't take much length for the cock to reach the distance required to hit your prostate directly, like a spearhead, making another slutty groan escape your lips. Further she slides, further down the thick meatpole, until, with a fairly cushioning smack, your butt finally hits the breadth of her sack.

Your vision blurring, and the wind knocked out of you, you reel in the intensity of the forceful penetration. For a second, time seems to stand still, or Lilnessa temporarily halts in her onslaught. You're completely speared, your insides surely shifted to accommodate her massive size. In a fruitless attempt, you call out to her, telling her you didn't get to lube the inside of your arse, begging her to pull out. As much as it was arousing to be filled and dominated by such a massive prick, this hurt, quite a bit. You try and move forward, sliding the cock out of your arse by a few centimetres, but your speed is too slow to attempt any true effort.

Lilnessa didn't hear you, or didn't listen. In her hazy spree, she snorted loudly, almost like a bull, before thrusting the weak distance you achieved back into your butt, slamming you full, vibrating your slutty arse around its length. You try again to move away, gaining less ground, and achieving an even harsher spank of a second powerful thrust. For now, you're at her mercy.

You hear the sound of her hind legs move back, and she starts to slide her cock outwards, stimulating your prostate roughly as it goes by. She reaches the beginning of the head, before slamming the whole length back into you, harshly, spreading you even wider. You gasp again, pinned further down towards the ground. You can feel her so vividly inside you, the intense, only just bearable heat, the muscles, so frequently rising and falling with each effort. Again, she starts to shift herself out of you, until the flare is reached, before another heavy thrust pushes your body further into the ground, abusing your passage.

You figure that the only way you're getting the most out of this is to relax- letting your arms go limp, you slouch forward, and call out to Lilnessa, pleading her to brutally fuck you. Despite the rough nature, you still the deep-seated need for this beast to ravage you. With another pull back, she slides you half way off her dick and rams you back to the hilt, repeatingly smashing her mass against you, picking up the pace, rocking your whole body with powerful momentum. You wonder if the other demons can hear the cries and moans you make as she viciously pounds your slutty butt, your pain fading in favour of intense satisfaction.

Her long, deep thrusts slowly increase to a crazed fuck frenzy. Being pounded into the ground, you moan repeatedly, dick twitching, prostate being ground into with each slide of her knobbly cock through your system. You can felt her head bulge through your passage, burrowing deeply, it's thick head stretching even in the furthest possible, previously pristine reaches into a body long, gaping hole. Tongue escaping your mouth, you let the sensations completely overtake you, feeling your whole body rise and fall with each savage thrust. Just as you begin to fall a deep trance, she slows her pace to a stop, leaving you filled, but at a standstill. With a long effort, she slowly slides herself outwards, until, with the loudest smack possible, she pulls her head free from your arse. You take a minute to look down, contorting your body to observe how far she's stretched you open, to observe the giant, abyssal gape. Your arsehole contracts, as if to grab at cockmeat no longer present in your system, and your whole body feeling unpleasantly empty.

With several taps of her hooves to your body, you take the holdup as a change of position. You flip yourself over, so you're facing upwards towards the centaur's well-built body. She still seems to be retaining her frenzy, however, as she tries to ram and thrust without actually taking the time to aim, missing your open arse completely. It's a fair surprise, given how large it's become, you'd figure it'd be a big target. With two careful hands, you start to guide her gigantic girth towards your open pucker, biting your lip as she resumes her long slide into your depths. With a now familiar, much less resistant slide, she reaches the hilt of her dick, pressing her thick balls into you body.

Your position is strange, but very welcome- on your upper back, your bottom half speared upwards, so you're moving up and down with each thrust of her erect cock. The position seems to more welcome bash your prostate, making you whimper and moan that little bit more with each pass. Her massive dick now filling you again, she begins to resume her harsh lunges into your abused, impossibly wide arsehole. At this angle, your erect cock hangs downwards with gravity, your balls bouncing with each smash of her pair into your body. Your body rocking up and down with each push, you can now hear your arse, so wet and slick with equine precum and lube, making deliciously wet slapping noises with each ramming you receive. The sound of your sloppy arsehole, so moist with her juices reminds you of her pair and their further contents- you wonder what her superior cum tastes like on your tongue and feels in your stretched butthole.

She continues her thrusts with continued effort, however the unmistakable sounds of a **** centaur in need of release are evident. You take another look at her bulging, brown balls, heavy and churning with their thick payload. She starts to grunt louder, her balls seeming tighter with each pound of your arse- you begin to ready yourself for the potential soaking. Not all of this can fit in your arse, surely. With a final few, violent thrusts, she gives a loud howl, her horse prick twitching with the incoming load.

The gigantic **** of a pent up centaur unloads inside you, the initial few spurts lubing the dick enough that it nearly slides out with the recoil of her monstrous load. Her flared dickhead is the only thing preventing it popping right out of your arse and giving you a spray down, the cum instead being pumped directly into your anus with rippling contractions all the way down her massively sized shaft. With your upwards position, its viscosity is overwhelmed by the **** of gravity, instead very slowly sliding down the walls of your abused hole. You feel its warmth slowly slipping down your insides with tantalisingly slow speed. The distance her shots travel, and the pure **** behind them mean that her ropes travel from the very entrance of your passage, directly into the deepest depths with little effort.

Very quickly, you're completely filled to the absolute brim, and her cock head is pushed outwards with the building pressure. As it leaves, you fall to the floor, her seed shooting out of your arse due to its massive amount and built up **** being released. Sprays of seed shoot far across the room from your butt, with copious amounts to spare still remaining. Her cock, continuing to orgasm, shoots out another tremendous load, coupled with another large groan from Lilnessa's lips. Your body, now ****, right in the line of fire, gets a full blast of very hearty smelling, extremely gooey seed. Your chest is coated completely with ease, the back spray hitting the underside of Lilnessa's body in thick globs. You take the opportunity to shift yourself downwards, mouth open, eager for your fill. The first, ample shot glances your cheek, giving you a good smell of the incredibly potent, dazzlingly masculine concoction, but not giving you your desired taste. Readjusting your body, you see that the next shot lands perfectly in your awaiting maw, for you to secure tightly with a closed mouth. Further shots are fired, splattering your face completely, until her dick begins to deflate, her moans behind to subside, and her cock now dripping with further seed.

Splashes of Lilnessa's cum begin to finally fall from her body with the **** of gravity, landing on your naked body, but doing little in the grand scheme of things- you're already coated completely from the waist up. You take in the warm taste of your reward, swishing it vigorously like mouthwash, reeling in the strong texture and taste. With a swallow, you slump backwards, completely exhausted.

Lilnessa very quickly crouches down onto both sets of knees when her rational side regains control. She's apologising profusely, giving you all sorts of excuses, but you silence her with a laugh, telling her she'll be the best fuck of your life. You clean yourself up, not accepting the towel she offers you, consuming all traces possible, toying playfully with your massively distorted arse whilst you catch your breath. It's even thicker than her actual diameter- she really got you stretched out. You thank yourself lucky that this is clearly a dimension where her size doesn't hurt you too badly, bigger cocks being better, due to the lack of consequences of gigantic cocks entering your previously tight, previously virgin butt.

In a few moments, the some of the girls enter the room, some clearly aroused by the sight of your massively open arse, Arisa herself at full mast. They claim they didn't hear anything, but a couple of giggles probably tell you that they heard how much of a buttslut you are for horse dick. You don't really mind, however. A few ask to touch it, tracing the now massive rim of your hole with long fingernails, before Lilnessa claims its time for the guest to leave, before someone higher up finds out and crucifixes the lot of them.

With a short spell, you're banished back to your own world- you make sure to leave a couple of weeks for your legs to get back into functioning order. You're pretty sure, even a week later, that Lilnessa's cum is still dripping out from the deepest depths in thick globs.
