The Night Visitor by Libellule_Sulfureuse for Annariel Midori

Summary
Ominis has nothing human left in him. All that remains is that glacial hunger which drives him, night after night, to feed on the ecstasy of women with virgin bodies and minds infested with unspeakable fantasies.
☆☆☆☆☆
This OS is a deliberately dark and smutty reinterpretation of the Zburătorul, a supernatural being from Romanian folklore, often likened to an incubus. He visits young women in their sleep, seduces or torments them sexually, causing a sickly languor, a gradual wasting away, and a consuming sexual obsession.

Summary
She didn’t think her birthday mattered. He took it as a personal offence. So no cake, no candles. Just Ominis, velvet, and a few bites from a serpent that’s anything but natural. Happy birthday, Evelyne!
⚠️: Use of a magical serpent in an erotic, and symbolic context;
A_N: This OS was published on 25 November 2024 before being made private 3 days later. In fact, I realised too late that I wasn't happy with it. So I reworked it. I hope you like it.

Summary
There’s something off about Sebastian Sallow. You ignored the signs and warnings, and now you’re in too deep to back out.
Sallow is a different kind of scum. He is feral, unburdened by pedigree, unrepentant in every way that matters. Dangerous not because he’s cruel—plenty people are—but because he doesn't see cruelty as a problem.
Sebastian questline rewrite, but I <3 villains.
