Proof of devotion

"Slut, speak the name of your master," Gray commanded.

"I have none," Alyona replied.

"False!" Samson felt himself shout, "I, Gremory, Duke of Hell, Captain of the Baldur Gate, Slayer of Samigina, Bearer of the Unholy Cingitur, am your master!"

As he yelled, thunderous cracking sounds filled the cavern. Samson felt pain like no other he and ever experienced, but his visage, fully controlled by the demon maintained its wrathful, triumphant leer. The altar and nearby candles disappeared into a sinkhole in the floor. Yet the dark melted off of the walls, lit by unseen sources of light. Then, with Samson trapped and screaming, the body which had been his began to change. His previously moderate tan darkened until it looked like he had been burned. Two modest horns pierced through his forehead, gleaming as if plated in gold. Lastly, a long tail with protruding spikes at the end burst out of his pants and snaked onto the floor.

"Ahhahaha!" shouted the body which did not seem to belong to Samson any more, "Say it, slut!"

The long tail whipped around and struck Alyona on her side, finally jolting her out of the candle's intoxicating flame. Large red gashes appeared on her torso where the spikes ripped her skin, but in moments had healed completely. She stood slowly, her gaze now fixed on Gray, but her face was unreadable.

"Bitch of heaven, I have defanged you!" the demon continued to shout. "Now you must submit to me and take up my mantle, as it is ordered in the ancient texts!"

The angel continued to stare.

"Ah, fuck," muttered Gray before spouting forth in the ancient language, "Milochtini faduani i Gaeneron sultina mal inoculendon!"

Light appeared in Alyona's eyes once more, but this time it was a distinctly ominous red glow. Gray smiled.

"Slut, name your master."

"I serve Gremory, daemon of lechery, and none other," said the ex-angel, in a voice that implied the fulfillment of desires. Immediately, a blast of pleasure brought her hands to her body, and her eyes sought those of her master.

"Prove you are mine," said Gray, his leering smile never fading, "and seek my favor."

Her body quivering with lust, Alyona sank to her knees once more, and crawled seductively towards Gray.

"Oh, mighty and lecherous Gremory," her sultry tongued professed, "I am but a limb, to be used to deliver your great and terrible judgement. I beg of you, grant me my only desire: to be filled with your seed, united with you in passion, and allow my mana to empower you now and forever."

Her lips closed around Gray's now-enormous cock. But she could only barely cover the head of the engorged golden-brown monster. Undeterred, Gray reached out with both hands and forcibly impaled her throat onto his daemonhood. A mortal would have died, but Alyona merely spasmed in greatest pleasure.
