"Are we ready for another round?" Lucifer's voice came from the surrounding darkness.
Alastor hung…kneeling. He was bound tightly by the chains winding across his chest; wrists secured within the links wrapping above his head. The large brimstone shackle was heavy on his neck; the chain to its ring hanging loose and dragging beside him.
"Heh…is that one of the questions?" Alastor smirked, his voice a crackling radio.
A chain slithered from the blackest of shadows; twisting and hissing as it found its way home; curling itself up Alastor's naked torso and tightening painfully. He hissed as the links burned more brands across his bare, scarred skin.
"Yes." Lucifer told him, stepping out from concealing shadows. "It was." He was shirtless – bare-chested – just as Alastor was; his dress pants and shoes the only remnants to the clothing he had been wearing.
Alastor starred at the King's exposed upper body. The radio demon's green eyes flared wide – hungry and gleaming – drool seeping from sharpened teeth. The base to each of his antlers thickened; the smooth bone becoming heavy and long as points branched higher and higher above his head.
"Are you enjoying yourself?" Lucifer asked him. "Still rutting I see…"
The demon growled; a low sound intermingling with the sharp sounds of a radio static.
"And, still losing." Lucifer sighed, another chain slithering past him to lift and strike out just like a snake; catching and winding itself through the ring to the shackle just at the base of Alastor's throat. The chain jerked and Alastor's neck was pulled sharply forward.
"You look like you have sobered up, though." Lucifer told him; approaching carefully. "Tell me, Alastor…now that my ichor has left your system; are you thirsty for more?"
Lucifer flicked clawed fingers; bringing sharp points against his own bare skin, just at the soft bunch of flesh that stretched across one shoulder. Slicing there, gold blood seeped and spilled from the cut; threading down his chest and abdomen.
Alastor snarled in answer; his eyes flaring brighter, antlers growing longer, his hair standing up – sharp and bristled; overwhelmed by his overpowering need.
"Yes…" The radio to his voice nearly screeching. "…your majesty…"
"Well, now." Lucifer stepped closer. "Honesty and manners this time. A reward for you…I think."
A chain dropped from Alastor, winding its way back into the dark as the other chains still supporting him shifted and moved. Alastor's hands were released but the chains encircling his chest and neck were dragging him backward so that when they found their placements; the radio demon was stretched fully on his back; pinned to the ground. He tried to move; trying even to just to be able to prop himself up in order to see what the King was doing; but the chain tightly secured to his shackle held fast.
Alastor's ears worked nervously. He was starring up into complete darkness; his body tense with the knowledge that Lucifer meant for him to not know what was coming.
When he felt Lucifer's hands on his legs - moving them so that they were spread easily wide apart - and the King moved between them, Alastor growled. The sound was low and warning; promising a deadly reciprocation to whatever the fallen angel intended; given the chance…
He felt the King moving, climbing over him so that he leaned across and over Alastor's chest; his hands supporting his weight from either side of Alastor's head. Lucifer's wide golden eyes matched Alastor's flaring bright green ones; a wicked smile spread across the King's face as he leaned himself closer to Alastor's face. Baring his sharp teeth and flattening his ears, Alastor fought to lift his head; meaning to bite. The chain restraining his neck tightened and any give that Alastor had found in it before was now lost.
Laughing, Lucifer smiled down at the sinner demon lying just beneath him.
"I promised you your reward. I keep my promises, Alastor." Lucifer told him, leaning closer so that they were face-to-face; Lucifer only just out of reach from Alastor's sharp and pointed teeth. Lucifer tilted his head; fully exposing his still-bleeding wound he had opened across his shoulder.
Alastor's growling choked in his throat; seeing the golden strands tracing down the King's chest; sparce warm drops falling onto Alastor's bare skin. The growling had turned into a brief but desperate whine for relief; Alastor's clawed hands digging into the ground beside him; finding no purchase – claws cutting grooves into the dark floor.
"I'm afraid you'll have to use that rather useful tongue of yours." Lucifer was telling him; leaning back just enough to give Alastor the best angle for full access.
Without a moment for hesitation, Alastor's tongue lashed from between his bared teeth – long and dripping - it lapped at the streams of golden blood. A groan emitted from Alastor; barbs from his tongue pressing roughly against the fallen angel's skin as he hungrily scraped for every…last…drop.
Alastor's eyes started glazing over and Lucifer chuckled.
"You're not a very fast learner…are you." Lucifer said darkly. It wasn't a question. Alastor's tension was gone. Drunk with the angel's blood; he retreated his tongue – eyes closing as he let his head fall back.
Leaving him to his buzz; Lucifer crawled back down to kneel between Alastor's long legs. He began working at the radio demon's dress pants; reaching just behind the seam at the crotch, finding the bulge within and sliding Alastor's seeping and engorged cock out.
Alastor shuddered; pleasurably. Gasping at the contact.
"You know," Lucifer said, holding the large penis in his hand. "I, too, can do some pretty…interesting things with my tongue." His eyes flared; sharply golden. "Shall I…demonstrate?" He asked in a purr.
"Yes." Alastor was groaning again. "Your Majesty."
"That's my deer…" Lucifer told him.
Using his own tongue now, he let it slither from between his teeth. Just as a snake's, it stretched and flicked itself so that it tortuously skimmed the underside of Alastor's cock – touching all along the base and shaft underneath then going to flick at the soft skin along his balls.
Alastor was panting. A redness was spreading across his chest and face; a slick sheen of sweat coating his skin.
Lucifer continued to teasingly flick his tongue all along Alastor's root; occasionally bringing it around to circle the shaft. The muscle there was tightening quickly.
Pausing briefly, Lucifer adjusted his hold on Alastor's throbbing penis. "Careful, you don't want to miss out on the best part." Snaking his tongue out; Lucifer carefully elongated the shape so that the forks lengthened and thinned. Expertly, he directed the tips to the slit at the head of the slick cock; sliding them inside.
Alastor bucked and Lucifer pressed clawed hands into each hip; holding him steady and he worked his tongue so that it slid in further.
"Ah…." Alastor was lost. The stimulation was too incredible. Timing it perfectly, Lucifer snaked his forked-tongue deeper before slowly retreating it back out. Alastor's body shook. Removing his tongue entirely; Lucifer took Alastor's cock fully and quickly into his mouth; biting down sharply just as the organ tightened and sprayed cum.
Softly coiling his tongue all along the twitching cock; Lucifer sucked and swallowed before dropping it limp from his mouth.
Lucifer stood up from where he had been kneeling; there, between the radio demon's legs.
Alastor laid, still panting and gasping. The deep red color his skin had turned was contrasting the brands of chain links in an interesting way. His clawed hands were shaking and he was drenched in sweat now. His body twitched; still feeling the waves of ecstasy crashing over it.
Lucifer laughed; stepping away to loosen his own dress pants now. He paused; then as if deciding something he slipped out of the remaining clothes entirely.
"You certainly know how to take your…licks." Lucifer said. "If you actually are in the middle of a rut though…it's you that could do with some mounting. I suppose you're in enough of a manageable state that I could allow it."
Lucifer stepped back to where he had left Alastor; still tightly restrained to the floor.
"What say you?" Lucifer asked him; the chains around Alastor coming loose now but never fully leaving him.
Alastor moved slowly. He was dazed; both from the remnants of ichor and the orgasm. Turning, he went to stand up; then thinking better of it he knelt back to the floor; eyes on the King.
"Your majesty…" Alastor knelt; looking up – compliant.
"Good boy." Turning away from him – fully naked - Lucifer waved a hand and every chain holding Alastor dropped and went away into the dark; every chain save for the one holding to Alastor's heavy brimstone collar.
Alastor smiled; standing and going to the King; dragging his chain with him.
Stopping to stand just behind Lucifer, Alastor paused; eyes flaring green, his antlers curling and twisting ever upwards.
"You may…regret this." He said before he sunk the claws of his left hand into the flesh of Lucifer's left hip; pulling the angel into him and spilling more blood. His right arm wrapped around the King, his clawed fingers finding his face and mouth; shoving them inside. Snarling; he bit deep into the wound at Lucifer's shoulder; swallowing hard as golden liquid poured out.
"Ahhhhhh…" Lucifer sunk to his knees and Alastor followed him down. His teeth still buried in the fallen angel's shoulder; he forced the King down on all fours. Lucifer choked on his fingers; golden blood pooling on the ground from his wounds.
Gasping, Alastor released Lucifer's shoulder. His vision blurred and darkened; the influence of angelic blood mixing with the influence of his rut. He was already hard again; his erection pressing fully into Lucifer's bare back.
"Now…my King." Alastor was purring darkly; sliding his fingers from Lucifer's mouth. "I will gift to you the most fitting of thrones…"
Lucifer gagged; blood and spit running down his chin.
"Do your worst…my deer."
Alastor jerked awake; déjà vu catching him even in his 'half-asleep' state.
"Oh, what the Hell-" Followed by a sleepy yawn. "What fucking time is it?"
The room was pitch black; then a bedside light came on.
"Uh..." Alastor said, shifting awkwardly in the bed.
"AGAIN!?" Lucifer exclaimed loudly.
"Well…" Alastor replied.
"If this keeps happening, you and you're one-eye monster are sleeping somewhere else!"
