[Warning: Mature Content R-18+ | BL] A manipulative stepson uses his innocent "good boy" persona to seduce his strict stepfather, slowly eliminating anyone who stands in the way of his obsession. ----- To the outside world, Leo is the perfect stepson. With his bright green eyes, shy smile, and helpful nature, he is the picture of innocence—a "good boy" who just wants to make his family proud. To Damon Blackwood, Leo is a source of confusion. His stepson is clinging, affectionate, and dangerously beautiful. As Leo starts his internship at Damon’s company, the boundaries between stepfather and stepson, boss and intern, begin to blur. Damon thinks he is the one in control. He thinks he can discipline the boy, teach him boundaries, and keep their relationship professional. He has no idea that every "mistake" Leo makes is calculated. Every brush of skin is a trap. Leo doesn't want a father. He wants a Master. And he is willing to destroy anyone who stands in the way of that fantasy. As a strange illness takes hold of his wife, Damon finds himself falling deeper into Leo’s web of lust and lies. By the time he realizes the "good boy" is actually a monster, it might be too late to escape. "I'll be good, Daddy. Just don't look at anyone else." ----- Author Note: This story contains dark themes, obsessive behavior, and moral ambiguity. Characters are NOT related by blood.

After her death, Lilith awakens in a world where fourteen billion players struggle for survival, power, and the right to continue existing. Over Ten million of them have become Demon Lords, each building their own race, their own territory, and their own army. Demonic Dragon Knights command vast legions, Vampires rise to build empires, and Lords of Catastrophe leave nothing but ruin in their wake. Yet Lilith enters this world as the Primordial Succubus Monarch - and quickly realizes she cannot walk the same path as the others. Instead of endless armies, she is given only three succubi, each unique in their own way, and the system permanently seals her ability to summon more. In a world where power is measured in numbers, such a gift feels more like a death sentence than a blessing. If she wants to conquer this world, she will have to take armies from other Demon Lords, grow stronger despite her limitations, and prove that a demon of desire is not meant only to seduce - but to fight. And above them all stand the Heroes… beings created for one purpose alone. To hunt and kill Demon Lords like her. And Lilith would soon realize… that neither Heroes nor Demon Lords were the true predators of this world. *** You can support me on Patreon: https://patreon.com/TorqQ
