There, in the cool of the darkness Alastor was on his knees. Tight chains binding his legs and his wrists; solidly to his back. His long ears worked separately back and forth; side to side as he tried to orient himself. These shadows surrounding him were not his own and they were not his friends.
"Now," A voice came from the dark. "Are we ready to begin?"
A flare of red; bright wide eyes appearing from the black as the shadows were cast aside; slithering outward. Lucifer stepping into their midst; red eyes aglow, tall, twisting horns rising high above his head, all six wings outstretched wide behind him.
Alastor's grin widened, eyes sharp, and narrowed on the King.
"How about a game?" Lucifer asked him. "The prize is your release. The rules: I ask you a question. If you answer honestly, I take a chain away. If you refuse to answer or if you dare to lie to me, I'll add another."
Alastor's smile tightened; he tested his restraints but there was no give.
"So," Lucifer began, "Why are you here, Alastor? What is keeping you at the hotel?"
"Heh," Alastor gave a breathy laugh. "The entertainment. Truly."
"A lie." Lucifer said coldly. There was a hissing as a long black chain uncoiled and slid from the surrounding darkness; it slithered loudly across the cool, smooth floor and wound its way around Alastor like a snake, tightening across his chest. Heat burned from its links. These were no heavenly bonds; these chains were cast from brimstone.
"We'll try again. You made a deal with Charlie." Lucifer told him. "What do you intend to ask of her?"
Alastor said nothing: his eyes never leaving the King's, ever smiling.
"Hm." Lucifer watched him as another chain came slinking from the dark. "You're doing quite poorly. You might have found your freedom already had you played your cards right." The second chain coiled around Alastor, sliding into place just opposite of the last. Alastor suppressed a sharp hiss as the links tightened, burning skin despite his suit.
"You were gone from Hell for quite some time…were you not?" Lucifer gave him a cold smile.
Lucifer was offering him an easy one now; a simple 'yes' or a 'no' would suffice. Alastor refused to take the bait laid out for him. The answer was an obvious enough one; he'd lose more answering it than he would gain.
"What, is it your Majesty? Afraid I might disappear again? Afraid you might miss me-?" Alastor hadn't quite finished the question when a large, heavy black shackle shot from the darkness and closed around his throat. This time, he couldn't help the air leaving his lungs as he gasped; the brimstone collar searing his throat.
"That wasn't an answer." Lucifer told him, holding the long and winding end of chain attached to the burning shackle.
"Now, tell me," Lucifer wound the chain in his hands; tightening it so that the brimstone pressed tighter to Alastor's neck, burning him more.
"Who owns you?"
Laughter bubbled up from deep in Alastor's chest, cackles erupting from his insane smile.
"Are you going to answer the question?" Lucifer asked him, placing more pressure on the chain and stretching Alastor's neck painfully.
"I-" Alastor was still laughing, "I can't!" His body was shaking, jerking from the hysterical fit he was having.
A black chain had begun its way to him, slithering quickly to stop and pause just before touching his legs. The chain slowly slid back; being pulled straight back into the darkness. One of the chains wrapped tightly around Alastor's chest loosened and then followed it. The relief from just one chain removing itself from him was incredible.
"That at least was an honest answer." Lucifer told him. "But even with that, I'm afraid you've lost our game."
The chain remaining across Alastor's chest pulled back sharply, yanking him onto his back. Bringing up the slack to the chain that shackled his throat; Lucifer pulled it tight. The chain encircling Alastor's legs let go, slithering upward along his back to wind itself so that it formed a tight connection from the chain that still held his wrists to the brimstone wrapped about his neck. Before Alastor could get his legs beneath him and gain some ground; Lucifer pushed him back down with a boot; pressing it firmly into the radio demon's chest.
Gasping again, Alastor bared his teeth; ears curling and laying flat as he glared up the tight links of chain and into Lucifer's red, glowing eyes.
"Well, this is becoming quite problematic for you." Lucifer told him; "You seem to be actually enjoying this."
Lucifer's boot left his chest, moving now so that he was stepping into the inside of Alastor's left leg; angling it so that a noticeable bulge was fully exposed at the seam of his pants. Shifting the boot, he slid it so that it rested just against the tent in the fabric.
A growl was building in Alastor's throat when the chains were noisily moving again; this time they dragged him upward so that he was standing before Lucifer; he could comfortably set and stand with his feet down but the chains were fully supporting his weight.
"What were the words you used earlier?" Lucifer asked him; not looking at him now but looking at the growing bulge at his crotch. "Your Majesty…?" He looked up at Alastor; a wickedly suggestive smile spreading across his face.
Growling, Alastor twisted against and tested his chains. There was a sudden release of his wrists, the chain falling away briefly. He pulled his arms apart and brought his hands forward before the chain had regained its hold, this time tightening around his wrists and yanking his arms upwards.
"Fuck." He twisted and yanked; finding no release this time.
"Oh, but it looks like you are quite happy to see me, Alastor, standing before you like this…" Lucifer told him, eyes at his crotch again. He had released the chain from Alastor's collar, letting it hang freely now. "I suppose you could just be hiding something from me just there, but I have my doubts."
He placed a hand at Alastor's waist, the other lightly touching where the fabric was being pressed outward, a clawed finger slowly circling the spot.
Alastor had stopped struggling against the burning chains; focusing instead on trying to control what his body was doing; trying to control his breathing.
"I better check…just to be sure." Lucifer spoke quietly, the hand at Alastor's waist sliding along the waistband of his pants, a claw hooking the edge and pulling. His other hand slid between the fabric and Alastor's skin, fingers closing around his still-growing member.
At his touch, Alastor's breathing was slowly turning into sharp pants. He wasn't just burning from the brimstone now. "Ah…" He gasped. "Your majesty…"
"Well, that didn't take long." Lucifer told him. Pulling Alastor's enlarged cock out, he held it firm in his hand; rubbing his thumb along the slit, spreading pre-cum all along the tip.
Alastor's body shuddered and he started panting even more heavily now.
"Fuck, Alastor." Lucifer continued to move his thumb along the tightening skin, softly pressing into stiffening muscle. "This thing is huge and throbbing. When is the last time someone actually touched you?"
Alastor's hips jerked; his face had reddened and his skin had taken on a soft sheen. He was absolutely quivering now. "Please…your majesty…"
"Well, I suppose I should reward you for finding some manners." Lucifer said, closing his hand fully around Alastor's shaft now. "Offer you at least some release." Placing his free hand on Alastor's shoulder he began pumping his penis.
Alastor's head went back; his heavy panting racking his body as his hips began thrusting. His dick quickly stiffened in the King's hand; spraying cum. He felt his knees give out beneath him but the chains holding him were tightening and moving him again.
He was pulled back; chains fully releasing his hands now and sliding into the dark. But, the chains wound around his chest and shackled to his neck remained; holding him fast, and away from the King.
Lucifer stood where Alastor had been; licking the cum from off of his fingers. Alastor's body shuddered briefly before his eyes burst into green; his antlers growing and reaching wide.
"I thought that might send you into a rut." Lucifer told him.
Alastor was snarling now; ears pulled flat against his head. His eyes were wide with a ravenous and feral hunger.
"You are quite powerful, aren't you." Lucifer casually noted. "I have you in the strongest chains in Hell and you are still a bit of a problem. I bet you have power that even you haven't tapped into yet." He laughed. "It was very lucky for Adam that you made your little mishap when he faced you; I believe you actually could give me some grief even…under the right circumstances."
Alastor's snarl deepened.
"You're going to have to get more of a grip on yourself before I let you touch me." Lucifer told him, smoothly shifting his form so that his horns and wings were no longer present.
Alastor's ears lifted slightly, one twitching briefly. His snarl was dying in his throat; some of the craziness leaving his eyes now.
Lucifer was slipping out of his suit jacket; unbuttoning his shirt.
Alastor watched him with bright green eyes, quiet now. His ears were perked; twisted forward. His hair rising in his excitement, antlers still branching out, long and tall.
The chain to Alastor's collar slid across the floor and into Lucifer's hand. He pulled it taut; matching eyes with Alastor now.
"If you bite the absolute shit out of me, I'll put a muzzle on that pretty face of yours." Lucifer told him.
Alastor smiled widely, exposing his teeth, salivating.
"You're much too excited for this." Lucifer told him. He loosened the waistband to his pants. Reaching inside, he pulled himself out, holding the large penis in his hand.
Alastor's eyes widened; his smile growing.
"What, you didn't think I wasn't going to give you anything to work with?" Lucifer asked him.
Not saying anything, Alastor knelt to the floor; his eyes never leaving Lucifer.
Lucifer, the chain still in-hand, pulled him forward. Alastor, his eyes ever on the King, slowly crawled to him and then raised himself up onto his knees so that he was level with Lucifer's waist.
Lucifer met his conduct in kind with the inside of one wrist, offering it to him openly.
"You won't hear this when I tell you…" Lucifer was saying, as Alastor bit sharply into the skin; hot golden blood dripping from around his lips. "But, you will want to take it easy with that it's…." Alastor started to sway drunkenly. "Potent."
He grabbed Alastor by the base of an antler; steadying him. Gold seeped from the corners of the radio demon's mouth. The chain encircling Alastor's chest came loose, letting go and pulling itself into the dark.
"Even at that," Lucifer was saying, removing Alastor's suit jacket from his torso. "You're more of a lightweight than I expected." He tossed the jacket, shirt, bowtie – all to the side. His smokey skin was painted in scars; red hot chain-links branded into the canvas.
Alastor's swaying had stopped. His clawed hands finding either side of the King's hips. Tilting his head so that he was watching Lucifer watch him, he brought his face close to the erect penis. Using his tongue, he licked the shaft; beginning at the root and working toward the tip. Lucifer's grip left Alastor's antler; fingers burying and twisting into the long, soft fur between both pedicles.
Lengthening his tongue; Alastor followed the shaft back down, then allowing it to elongate even more he slithered it along the base of the engorged tissue, wrapping and coiling it firmly around the quivering cock. Small, soft barbs from his tongue pressed into the sensitive skin; sending a barrage of sensation down the stalk.
"Fuck!" Lucifer gasped at the stimulation; nearly doubling over.
Eyes still watching the King, Alastor worked his tongue so that with it wrapped firmly in place; it was pushing and pulling Lucifer into coming undone. Pre-cum flooded his taste buds and with one final pull he had Lucifer's cock fully in his mouth.
"Ah…" Lucifer groaned, hips thrusting; his hand a tight fist in Alastor's hair.
Alastor met his thrusts, taking the penis deep into his throat; his tongue coiling and uncoiling all throughout. He was burning again; a dull, throbbing heat aching in his own groin again. He felt the King stiffening in his mouth; felt the sharp jerking of muscle just before the release -
Alastor jerked awake.
"Everything ok?" Followed by a sleepy yawn. "Fuck, what time is it?"
The room was pitch black; then a bedside light came on.
"Uh…I might have a small problem." Alastor said, shifting awkwardly in the bed.
"WHAT IN THE UNHOLY HELL IS THAT!?" Lucifer exclaimed loudly.
"Said problem." Alastor replied. "You, uh…want to help me with the solution or shall I work this one out myself?"
"I've never seen it get that big." Lucifer was saying. "It won't bite me will it?"
"Oh, for fuck-"
"I thought you didn't get so…excited…about stuff with this…kind of stuff."
"I didn't say it NEVER happened!" Alastor snapped.
"Are you going to tell me what you were dreaming about?" Lucifer asked.
"No." Alastor told him. "I think you have enough ideas."
