With pleasure

How wrong you were to fight Lilith. The pleasure that courses through your veins is exquisite, and you aren't even fucking. As your eyesight returns you find yourself at the small room in the antechamber. Ah, yes, the Purestone. The dark veil that surrounded the room is gone, leaving only a white door.

With your powerful muscles, you kick the stone door to bits as if it were made of thin glass. Stepping inside, you see your prize.

On a pedestal that is lined with runes similar to the map that led you here, lies an oval-shaped glowing white stone. You can sense it's righteous aura, and all you can feel is an urge to twist and defile it.

You reach your red, talon-tipped hand and grasp the Purestone. According to the seraphs, this should have killed you, but your mistress knows better. Thalinya and the seraphim were right: your heart is pure. Before it was filled with pure hope and good, but now only dark depravity lies within. And so Lilith found the loophole: one who was pure good, can be made into pure evil, and should one bearing a pure heart of darkness touch the Purestone, well...

As you pull the Stone from its pedestal, a surge of euphoria washes over your being as you drain the aura of hope and love from the Purestone. Stroking your huge incubus cock, you point it at the stone, releasing your black semen onto its surface. The now-empty stone absorbs every last drop, turning a roiling blood-red.

What was once a key to stopping Lilith is now one of her most powerful assets.
