"Well, I thought I heard something." Raze the succubus flicked her tail in frustration and folded her arms, pressing her large breasts against her chest and further pronouncing her cleavage.
"No, I definitely did too." Char the incubus looked around the small dark room and clucked his tongue. There was the sound of dripping water, and a low thrumming ambiance, but other than that, no trace of the noise that they had heard before. His tattered wings twitched and he scratched at his steel-solid abs with an obsidian fingernail. His gaze roved around the empty room until it fell, once again, on Raze.
There wasn't much light to go by in the little room, but Char didn't need any. She might as well have been luminous herself. The soft, fleshy curve of her ass, her long, toned legs, and her arched back supporting two heaving, magnificent tits. He felt a familiar weight between his legs as his cock hardened firmer than it usually hung. Char approached Raze from behind and wrapped his arms around her waist. He felt her tail curl around his leg and she looked back at him with large red eyes.
"Now, what are you doing?" Raze purred.
"Well, I figured, since we're no longer distracted..." Char began.
And then the howl rose.
There was a long, deep, screeching howl that set the two demons' teeth on edge. The two disentangled and pressed their backs against one another, facing outward against the possible threat.
"That is not what we heard before!" Char shouted over the din.
"No Fucking kidding!" Raze yelled back. "Maybe we should get the Fuck out-"
Raze was cut short as the floor beneath them burst with a torrent of slick, ropy tentacles. They wrapped around Raze's slender waist and coiled themselves around Char's wide chest and hoisted the two into the air, above the writhing mass. Char and Raze shared one frantic glance with each other before a tentacle drove into Raze's mouth, and then another into Char's. The slick appendages forced their way down the demons' throats, pistoning in and out with furious vigor.
Four more tentacles reached up and spread the demons' legs as they were suspended. Raze watched as a thin tentacle deftly wrapped itself around Char's massive veined cock and began to slither along its length, probing his cockhead tentatively as it worked his shaft. Char moaned with pleasure through the girth in his mouth as yet another tentacle, this one thicker than any currently preoccupied with him, pushed its way between his taut, firm asscheeks.
Char's moaning grew louder as the tip forced its way into his ass and widened out, stretching his hole until whatever creature had captured them was satisfied that its invasion was adequate. Then, it began to fuck him.
Raze watched as her partner's stomach became distended from the massive penetration he was undergoing. She felt her pussy moisten, and when she heard Char's scream of pleasure, it began to drool. As if on cue, two more tentacles found their way inside her; parting her pussylips and her soft round ass and coursing within both of her remaining holes. The feeling was unbelievable - her body was weightless and full at the same time. That, and she was getting fucked like the bitch she was.
As the tentacles began to thrust, she felt her tits bounce from the force of the fucking. She moved her hands to them and massaged them desperately, kneading passionately to stimulate them in symmetry with the rest of her spasming body. In response, the tentacle in her mouth reached deeper, and she felt her asshole stretch as the tentacle in her ass moved farther inside her. She felt her organs practically rearrange themselves as they made way for the two intruders, which pushed inside her until they both reached her stomach. The two tentacles clasped together and held each other in place, and then two more emerged from the blackness and snatched Raze's hands away from her tits, binding them in place behind her back.
The tentacle in her mouth then proceeded to use its slack to loop itself around her tits, binding the length leading into her mouth firmly between her cleavage. Raze realized through the haze of her punishment that she was being titfucked by a tentacle.
The glistening, muscled appendages worked Raze up and down on their length, sliding her through the rope on which they had skewered her, and she felt her arms and legs twitch helplessly with ecstasy of their own accord.
Eventually Raze managed to see far enough through the blur of her own lustful tears to find Char, who was still being pounded, jerked off, and facefucked. She watched her partner as his lithe, lean body contracted from the force of the pleasure, his muscles tightening from the effort of receiving so much mindblowing sex at once. And then, in tandem, there was a great shudder through the mass of tentacles penetrating her mate. The tentacles stopped moving for a moment, and then began to pound Char again, furiously, until they pushed farther inside them than they ever had before.
Char's flat, muscled stomach began to swell as a small geyser of sticky grey cum sprayed around the tentacle in his asshole. From the tentacle in his mouth, Raze could have sworn that she heard a desperate gulping sound, though it might have been her imagination. Her eyes widened with lust as she looked on - she had never seen Char filled with cum before. Normally, he filled her. If her heavily-gushing pussy was any sort of indicator, she did not mind the change of pace.
And then, just when Raze was beginning to wish for a load all her own, the tentacle around Char's rigid cock squeezed and coiled around the base of his shaft, and a massive load of her lover's cum sprayed across the room and onto her face, her belly, and her huge constricted tits. The blast almost knocked what little wind Raze had left in her lungs out of her as Char's gushing spunk painted her in his sticky sweetness. She felt the prehensile walls of her pussy contract around the tentacle that filled it, squeezing it and jacking it off to mirror her own pleasure, until she felt the pressure build.
The torrent of cum that followed was incredible. The two tentacles that had made rendezvous in her stomach began to hose her with their spunk, filling her esophagus and her intestines to bursting. Meanwhile, the tentacle in her pussy had pushed its way into her demon womb and began to flow with a torrent of warm grey mess, pushing every cavity in her body to capacity. The two demons screamed with pleasure as they were filled by the monster in the small dark room.
Then, the tentacles retreated. They slithered out of Char and Raze, leaving them suspended, constricted, and (almost) fucked senseless. Cum poured out of them in rivers, gushing from Char's widened asshole and Raze's gaping pussy. The mass of semen dropped out of the two and into the darkness below them where it splattered wetly onto the floor. Char glanced at Raze, who gave a mischievous smile back at him. Char gave a knowing shrug. He'd probably hear a bit more about that later.
