Ruined Divinity
In which Ignis is an angel and Ardyn captures and non-cons him
Ignis, an angel in human form sent to look after the Prince of Light, keeps his true identity hidden. No one knows except his charge's father, Regis... or so he thinks.
Ardyn, darkness incarnate, can sense angels. After one strategic visit to meet with Regis, he can tell that the young man standing at the edge of the room and quickly taking notes, is not human. His angel sense is tingling, and he can't resist the thrill of corruption.

Ardyn excuses himself and makes for a nearby side room, ducking inside and assuming the form of the young man he had just seen. The thrill of finding an angel after so long, one still pure, made him unbearably horny. He pulls out his cock, now beautiful and uncut and petal-soft in Ignis' image, and begins to stroke it slowly, pleasure overwhelming him.
Ignis, completely unaware, suddenly feels himself growing hard in his pants, and excuses himself in horror. For the first time, he was experiencing arousal, and it terrified him.
Ardyn quickly approaches orgasm, stroking the perfect cock in his hand roughly and feeling it twitch as it spurts thick, pure white semen onto the floor and over his hand. Step one of the corruption was complete.
Ignis, hidden in a room off the main corridor, feels a warm wetness fill his undergarments and is instantly overcome with nausea. Something was terribly wrong.
Ardyn shifts back to himself and returns to the throne room, finding that the young man is no longer present. He smiles to himself, deeply pleased, and asks Regis with feigned innocence if the "pretty young man" is okay.

That night, back in his own room, Ardyn again assumes Ignis' body. This time, Ardyn eases a thin finger deep inside this pure body's ass and crooks it, scraping the sensitive prostate with Ignis' short and perfectly maintained nail.
Ignis, in bed and sound asleep, wakes with a gasp as he feels something enter him and hit something sensitive. He's confused and afraid, but he can't deny that maybe, just a little, it feels good.
Dressed modestly in just a nightgown, Ignis rolls onto his back and spreads his legs without thinking, feeling Ardyn teasing at his hole and occasionally poking his prostate, moaning softly with a hand covering his mouth. He feels himself getting close, a strange feeling building in his stomach, and he clenches around nothing as he cums, staining his nightgown.
Ardyn continues fingering and toying with Ignis' body, unaware that he's already orgasmed on his own, and pushes Ignis into overstimulation.
Ignis begins to cry out, feeling violated and tortured, and then he cums again, unknowingly in sync with the red-haired man he'd met earlier that day, and it all melts away into pleasure.

Now, with the beautiful boy in his hands, Ardyn takes his cock into his mouth and begins drinking his divinity from him with every bob of his red head. He can sense Ignis' purity draining from him, the light fading from him until he becomes no brighter than a normal human.
With the last bits of purity drained from him, Ardyn lifts the young man and sets him on his cock, forcing himself inside as Ignis screams. When he cums, corruption sets in, and Ignis' veins turn purple.
