My Taboo Harem!

The system had told him he had awakened Soul Realm and Soul Energy after enslaving Kyle, after taking the first step on the Omni-Primordial Path, but he had not understood the scale of it.

How could he?

You did not understand the weight of an ocean while it sat sealed behind glass.

You understood when someone cracked the dam.

Now he felt it was... boundless, massive and absurdly dense:

A dark, luminous sea of higher power he had not earned through cultivation but stolen from destiny by enslaving an Original Progenitor. It had been sleeping inside him, locked and unusable, filling the edges of his soul like a treasury he was too weak to use.

And Sienna was drinking it.

Every millisecond, another huge surge vanished from him and entered her — drawn through the wet, gripping heat of her pussy as it continued its unconscious, rhythmic sucking on his cock. The bed creaked softly with each tiny roll of her hips.

Her thighs trembled against his sides. More of her virgin blood and slick leaked out around his shaft with every clench, darkening the silk sheets beneath them.

Every millisecond, another huge surge that vanished from him entered her:

Into her body, her soul, into the.... Nether Goddess the system called her.

Phei swallowed a groan, one hand fisting in the sheets beside her head... a goddess, huh?

"Will this harm me?"

[Ding! Apart from the loss of a large volume of sealed Soul Energy, Host will not suffer physical, spiritual, or foundational harm.]

Phei’s eyes narrowed.

"That is not enough."

[Clarification: The Nether Goddess is absorbing Soul Energy that Host cannot currently access, manipulate, or utilize and losing this excess sealed Soul Energy may be advantageous to you, Host.]

Phei stared at the blue text.

Then laughed once.

Breathless.

Disbelieving.

Of course.

Of course his soul being drained in bed by a reincarnated goddess was apparently beneficial. Why would anything in his life behave like a normal crisis when it could be an educational disaster with moaning?

"Explain," he ordered.

[Ding! Upon enslaving a Progenitor, or any being with a Soul or Bloodline of comparable rank and caliber like a progenitor, Host receives not only elements, abilities, and but also a large quantity of Soul Energy.]

[However, Host’s current soul has a limited capacity.]

Phei’s thoughts sharpened.

There was the missing piece...

Of course he already knew part of this:

The only reason he had not rushed to enslave another Legacy boy after Kyle was because the system had warned him his soul was too weak to carry another Progenitor-rank soul. One Original Progenitor was already an obscenely heavy thing to chain.

Two, at his current level, would be less "ambitious young dragon" and more "idiot found spiritually flattened under his own plot armor."

But now it was not just the soul itself but the Soul Energy too.

His soul could not hold another Progenitor-rank burden while still bloated with sealed Soul Energy he could not even use.

Phei’s eyes flicked down to Sienna.

The violet glow in her eyes had deepened. Her pussy gave another strong, unconscious clench around his cock, the wet suction audible as her hips rolled again. The bed shifted beneath them. Her breasts rose and fell with quick, shallow breaths.

More of their mixed fluids leaked out around his thick shaft.

The suction continued, powerful and intimate and terrible, dragging another wave from him. Sienna trembled, lips parting around a sound so soft and lost that it made his anger falter.

She was not here.

Whatever part of her remained conscious had been swallowed by the pleasure of power returning home.

Home.

That word moved through him unexpectedly, because right now the Soul Energy was not merely entering her, it was also being recognized.

Claimed and devoured by a soul that had once been a goddess and had never truly stopped being one.

Phei’s jaw tightened.

"Can I enslave another Progenitor after this?"

[Ding! No.]

Phei almost cursed.

[Host’s soul remains too weak to safely contain another Original Progenitor-grade soul. However, after the Nether Goddess completes the absorption, Host’s sealed Soul Energy capacity will be sufficiently freed to receive future Soul Energy rewards after you enslave another progenitor.]

[Host may currently contain weaker enslaved souls of lower rank and caliber.]

Phei breathed slowly.

"Convenient," he muttered.

Too convenient.

The thought came ugly and immediate and he hated it the second it formed, but he was not stupid enough to pretend it had not:

Dravenna had led him to Sienna because Sienna had needed him urgently:

And the moment her first time was taken, his sealed Soul Energy began pouring into her like an inheritance with legs.

Had they known?

Had Sienna done this on purpose?

Had his family moved him like a piece across the board, not because Sienna wanted him, not because there was a law of fate between them, but because the Nether Goddess needed his locked Soul Energy and no one had bothered to ask?

Something cold and uncomfortable opened beneath his ribs.

Phei looked down at Sienna, and for one awful second, suspicion touched the tenderness there.

He hated it.

He hated it enough that his face hardened.

But if he was right...

"SYSTEM."

[Ding!]

"Did Sienna intentionally take my Soul Energy?"

There was no delay.

[Ding! Negative.]

Phei stopped breathing.

[The Nether Goddess is as surprised as you are Host.]

[Current condition: Soul trance.]

[Explanation: The Nether Goddess’s soul has instinctively begun absorbing Host’s sealed Soul Energy through the completed intimate bond the moment she thought you were her everything and only person for her! It was not intentional]

[Host should note: The process was triggered by compatibility between you and the Goddess, awakening state and her giving in to you as her one and only Mate!]

Phei closed his eyes as relief moved through him so strongly it almost hurt more than the suction.

Good... good.

He did not apologize for thinking it.

He would not insult himself with fake guilt. Given how the night had gone, given Dravenna’s secrecy, given Sienna’s urgency, given every old monsters around him treating information like a family heirloom no one was allowed to touch, suspicion had been reasonable.

But he was glad he was wrong; so glad something in his chest loosened:

Sienna had not used him.

Whatever else tonight was, whatever Dravenna had known, whatever hidden clock had forced them to this moment, Sienna had not crawled into his arms and offered him her first time as a trick.

His family had not done that to him.

At least not this.

He could breathe around that. Phei leaned down, his forehead nearly touching Sienna’s.

"You scared me," he whispered.

She did not respond.

Her soulless violet eyes continued glowing, but the expression on her face had changed subtly. The pleasure remained. The trance remained. But beneath it, something almost peaceful began to settle over her features.

His Soul Energy was feeding her.

Not like mana strengthening a body but rain falling into a graveyard and making ancient bones bloom...
