It beat like a heart, the Heart of Corruption, and filled the den with its gentle reverberations. Each beat sent corruption further outwards and the den was completely drowned in it. The cultists within were empowered by these profane energies, making love for days on end and spilling their lusts freely.
The smooth crystal had merged with the altar it was birthed upon with its mother tending to it with a fanaticism worthy of praise from her demonic masters. The crystal demanded it be carved with profane symbols and the girl took great care with her hammer and chisel.
Two corridors went behind the altar room, leading into the newly-excavated chambers with Uzara and Albuzara inspecting the milking room.
Uzara watched as men stood chained by the arms and legs to the walls and letting out hot moans while corrupted roots that were defiled by the Heart swarmed over their bodies and cocks to milk them with no end in sight.
Cum flowed freely from them, their balls swollen from the treatment and corruption as they were slowly transformed into virile seed cattle, and it all was siphoned off into bowls and pots. The breeding whores required a healthy diet of seed to grow the foul spawn within them, after all.
"Milking goes well, mistress." Albuzara purred, her eyes roaming over the dozen men being brought to orgasm over and over again. They've been all been inducted into the cult beforehand with slave collars strapped around their necks denoting that they're now owned by Sin.
"I see. You've been busy in my absence," Uzara said with a loving smile on her plump lips. She'd been absent from the cult for the past week, having been busy corrupting and putting plans into motion back in the Imperial palace. "How many expectant mothers do we have in the den?"
She was curious as to how many women have been bred thus far. She wished that they were allowed to use their powers to quicken the pregnancies or have multiple children in one breeding sow but she'll have to wait just a little longer.
"We're counting over seventy. We're busy digging out more chambers for all of them. Those who couldn't fit are kept in the neighbouring houses." Albuzara answered in her chirpy and happy voice. She loved being the cult's Matron.
"Very good. Nosfertez has told me he will be bringing fifty or so slaves today. So be prepared for quick inductions and breeding when they arrive." Uzara told her, turning around to go down the meticulously sanded and polished corridor that had been dug out only three days ago. Albuzara followed behind.
"Oooh, how so?"
"It seems the elves had sent assassins and have slain the slaver owning them." Uzara murmured. She hated to see these mortals live in such a harsh way; murdering each other. "But do not fret, Nosfertez will bring them all here so that they can enjoy our love."
She could sense Albuzara vigorously nodding behind her. Then she stopped at an opening with open curtains - there is no such thing as privacy in the cult - and looked in.
It was a relatively large chamber covered in pillows with softly glowing purple crystals inset into the walls, casting a light purple light on the moving naked bodies within. Moans left the lips and throats of pregnant women as the male cultists did their duty in directly feeding the demonic spawn within them.
It made Uzara's heart flutter to see such debauched love, especially when she knew that most of the women were being made love to by their fathers, sons and brothers. She could also see the incredible power that was Sin and corruption as it revitalized and healed previously debilitated, diseased and starved paupers found on the streets of Talasia.
The air smelled of unwashed musk, seed and sex, a consequence of both corruption and unceasing orgies.
Albuzara made a noise behind her and she turned to notice the young demoness sporting an engorged and lovely cock for her troubles. "Now now, you're the matron. You have duties."
"I-I know but..." Uzara saw determination settle in her cute breeding whore's red eyes and she smiled encouragingly back at her.
"That's a good girl."
Albuzara beamed at her mistress and once again followed as Uzara continued her inspection. There were two more chambers left to inspect on the other side with the first being the large bedroom where men slept in well-fucked piles when they weren't busy with cult duties feeding their seed to the breeding sows.
The paupers and beggars of Talasia had learned to live the life of inaction and borderline sloth so it came to no surprise to Uzara when the new cult members easily took to the easy life of never having to struggle for food and hiding in an alley somewhere.
Here she could see yet another effect corruption and Sin had upon the mortals. As they are so close to one of the darkest sources of profane energies and spending most of their time in the den, their bodies began to change as well.
What started as a slight difference in character and body mass quickly and rapidly grew as the stronger, more aggressive men developed into strong and toned specimens while the weak and meek slowly transformed into effeminate males that the former fucked into submission.
Loving domination is a great part of demonic culture and Uzara was pleased to sense no negative and evil emotions coming from the mortals as she watched a curvaceous male being facefucked by one of the bigger ones.
"Taught them well, too." She said, glancing back at Albu with a smile. This made the young demoness grin from ear to ear.
"Some had a harder time accepting the love so me and Jalaz fucked it into them!" Albu said with a giggle that made Uzara chuckle.
"Speaking of Jalaz, any prime breeding stud candidates?" Uzara then asked, looking back into the den to inspect the naked and toned bodies of the dominants. Corruption somehow brought out the prime in the mortal and Uzara liked what she saw in the younger ones who looked fit and hung under the influence.
"Uhm, there are a couple but I've been waiting for you to do the selection, Mistress."
"Bring them to the throne room, then. I want to try them out myself." Uzara said, licking her plump cocksucker lips. It's been a while since she'd taken a good cock.
Uzara had settled on her grand throne behind the altar, the stone cock on the seat sliding deep into her all-consuming cunt and watched as Albuzara brought three naked and hung young men to her. One looked to be just barely over eighteen with his toned muscles filling out into a proper dominator.
