Nightmare rumbles quietly, not yet ready to wake up. He distinctly recognizes being uncomfortable but his head is too foggy to care– sleeping seems much, much nicer at the moment. His horns are pet, someone making soft cooing noises while hes nudged.
Nightmare growls low in his throat, more irritated than threatened. The noise comes out weak and warbled.
Cold leather slips over his skull next. Its snug, cold metal mesh covering his teeth.
A muzzle. Nightmare shakes his head, trying to dislodge it but only succeeding in making his skull spin.
He remembers the muzzle, he wore it when being transported to the reservation, and again after he was injured and they looked at the wound.
The humans urge him forward again, gently pushing on his scaled flank and encouraging him to move. The drugged hybrid clumsily rises to his feet, paws dragging against the floor and letting the rope attached to his nose ring lead him.
The pressure was uncomfortable and in his current state he was helpless but to obey.
His lower chest is stopped by a wooden bar, his fuzzy mind trying to figure out the obstacle. The humans make clicking sounds, pointing. After a moment Nightmare lifts one of his paws, clumsily stepping over the bar.
He stumbles a bit, sliding forward until his back legs rest against it. There was another wooden bar in front of him, this one vertical with planks bracketing it on the sides. Chafing rope is thrown around his back, looping over his lower chest and arms, the humans working quickly to tie a makeshift harness around him.
Nightmare looks down to inspect the itchy bindings, but his head is yanked upwards and tied to the vertical post. His clawed hands come to scrabble weakly at the muzzle, only for another human to wrap them up snugly in more rope and attach it in similar fashion to the muzzle.
Panic begins to bubble in his chest, but his body is too sluggish to react properly. His paws are getting similar treatment– tied and attached to the posts, he can't move at all, can't escape, he feels too weak to growl and snap, what did they do to him?
For the first time in a very, very long time, Nightmare feels scared. He wants to curl up and hide behind Dream like when he was a pup. The thoguht of Dream makes a whine escape his throat– where was his brother?
Nightmare wiggles in his binds. They're painful, too tight and will probably leave bruises. Hands are petting his flank again, two humans sliding a large leather strap and securing it around his belly, a smaller one is attached to his tail. It takes a bit of effort for them to lift the weighty appendage up, but they manage and attach the two strap with a leather rope and buckle, keeping his tail suspended.
Nightmare flinches as his cunt is exposed to cold air, uncomfortable and feeling far too vulnerable. He yelps as a gloved finger slides inside, wiggling a bit to feel around. The centaur frantically moves his hips– the finger slipping out. The human seemed pleased with whatever they were looking for, peeling the glove off and giving Nightmare's rump a pat.
They leave after that.
He doesn't know where he is, the concrete room is dark and cold, the only light streaming in from the door behind him. His mana lines swirled angrily, trying to dispel the mystery drug they pumped into his system.
A faint heat settled low in his gut while he trembled. Nightmare's skull spun, his mouth felt dry and his spine hurt all the way down to his tail, aching from being held up.
The warmth grew, spreading to the rest of his body, making him feel hot and uncomfortable. The pressure point where the bindings dug into his body burned. No sooner than the thought had left his muddled skull the heat faded, leaving him cold and shivering and aching for something warm.
Nightmare quietly chirped, suddenly wanting nothing more than to curl up with Dream, to feel his warm body over him, gently grooming each other, before Dream would bite down on his collar bone, hands sliding around his waist while he mounted him and–
The heat crashed back over Nightmare's body tenfold, making him nauseous at the suddenness. He panted, vision blurry.
WHAT was happening? It felt like he was in heat– but he wasn't supposed to have a heat this year. Was it the humans?
The dragon whined, trying to look around the barren room with his limited movement. It smelled the same, like humans and chemicals, with the faint scent of dust.
Fresh air wafted from the crack of the hatch door, no doubt leading to outside. Nightmare keened as the warmth ebbed away and he was left shivering again. Warm slick trickled out of his cloaca, his entire mound the only heated point on his body now.
He wanted--no, needed Dream. Where was his brother?
The beginning of his warbled cry was cut off as the hatch behind him slowly screeched open, making him flinch.
The room was bathed in light, Nightmare could hear the humans speaking, high pitched and encouraging. He never bothered to learn the language– now he was regretting it. Maybe he wouldn't be so in the dark.
The scent hit him, making him freeze.
The unmistakable natural smell of a centaur, musk and magic, with undertones of precious meals and the forest. There was the undertone of another scent, unique to each, sweet and young.
Killer.
Nightmare snarled, unable to turn his skull and see what he was doing.
Killer was barley older than a pup, having just reached adult hood this year. The already rowdy young hybrid was a headache to deal with once he reached age, constantly nipping and trying to mount Nightmare, not caring that the much older showed no interest.
Nightmare would always growl and swipe at him, making Killer chitter and scamper off until he was ready to torment the ancient centaur again.
But now?
Nightmare thrashed in his ropes as he heard Killer cautiously step into the room, claws tapping against the concrete. The bindings burned, but he couldn't escape.
Nightmare snarled, he couldn't see what Killer was doing, making him panic all the more. The cold flash was replaced by heat again, he could smell his own pheromones in the air.
After a moment Killer came into view, slowly circling Nightmare with wide eyes, head ducked as he tried to figure out what was happening. Nightmare growled low in his throat, jerking. The nose ring was pulled almost painfully in the process, making him freeze and whine.
Killer also froze, he seemed nervous.
The younger hesitantly neared, loudly sniffing Nightmare, getting more confident when he slowly realized Nightmare wasn't attacking him. His back arched like a cat when he rubbed against Nightmare, purring and circling him again. Killer seemed pleased, far too pleased, making Nightmare snarl and snap from behind the muzzle.
Killer neared his back side. Nightmare froze, trembling when he felt small puffs of air against his cloaca as Killer scented him. He relaxed when Killer pulled away, only to yelp as a weight settled on his back.
Killer was mounting him again, but no matter how much Nightmare thrashed and growled he couldn't shake the smaller off.
Killer's hands settled on his back, front paws wrapping around his middle. The rope burns where it tugs and presses into his ecto, but he barely notices it when he feels Killer's cock sliding out of its sheath. It's not as big as Nightmare, but there's barbs covering the length, Killer probably doesn't know how to sheath them yet.
Nightmare trembles in fear, he's truly helpless, but clings to the hope that Killer isn't able to figure out what he's doing, clumsily rutting against the elder, the tip pressing in between the slight swell of Nightmare's udders.
It occasionally catches on his entrance– making him clench with need fear, flinching when Killer growls in frustration, angling his hips and forcing himself inside.
The stretch burns, the barbs uncomfortable as they press against his walls, but Nightmare takes a deep breath and tries to calm himself. It’s not that bad, he can just try to bear it and–
Then Killer pulls back, the sharp barbs dragging and scraping-- Nightmare feels his sensitive walls tear and he cries out.
Killer pants wetly against his back, not big enough to reach his head or neck, humping into him with short deep thrusts that alight each movement in pain.
It hurt, it hurt so bad.
Nightmare was helpless as he tried to buck Killer off, clenching down unconsciously and feeling the spikes dig into him. Warmth that was definitely not slick leaked out.
Nightmare tried. “K-Kill-” his quiet plea was strangled--cut off when Killer growled and his cock started to swell. He sped up, the slight knot kissing Nightmare's lips, being forced past them every few thrusts and adding to the pain.
One of Nightmare's claws crack off as he digs them into the concrete, trying to ground himself, leaving scratches into the cold stone.
The barbs scrape over the same scratches inside his cloaca, opening them up more each time and Nightmare sees black spots dance in his vision.
His teeth are clenched and head bowed, tears spilling liberally down his cheek. His body is jostled with each rough thrust.
The knot swells more, forcing past his entrance with an unbearable stretch before getting caught. Nightmare chokes--stars it HURT but at least it was over, he could try to calm down and ignore the pain while they were locked together, be–
Killer made an annoyed sound, tugging the knot out as it began to swell to its full size. He started pressing inside again, forcing the knot back inside after the first few thrusts, the entrance tears, the slit being made larger to accommodate for the size of the knot, and Nightmare screams.
The knot pops in and out– Killer has no idea what he's supposed to do after all, he's never knotted anyone before–then finally he stills, letting it rest inside as hot cum spurts and fills up Nightmare's abused insides.
Nightmare is sobbing now, barely awake as he's tortured. Blood and magic pool at their feet, he's never been in so much pain before.
After a few minutes of Killer's soft purring and Nightmare's pained cries, the younger decides he wants more. He's still cumming– the knot hasn't died down, but he forces it out anyway, pushing it right back in.
The movement causes all the previous tears to burn, Nightmare can't take it, and he slumps in his bonds as the world goes black.
