Isekai'd into the Monster King's Bed

I wished for a world with magic and monsters and someone who'd actually want me. I should have been more specific.Elliot has spent ten years drowning in a soul-crushing office job, lonely and invisible and desperate for something more. So when a car sends him hurtling into the dark, he wakes to get exactly what he wished for: another world, a remade body, and a palace of black stone ruled by monsters.The catch? He is delivered to the bedchamber of the Monster King himself, a towering, horned, red-eyed beast who murdered his own family for the throne and keeps a string of thralls to feed his appetites.Elliot has never so much as touched a man. But the king is enormous, dominant, and utterly certain he's playing some game, and once those clawed hands are on him, Elliot discovers he wants the monster far more than he wants to escape. A steamy MM monster romance with a huge dominant monster king, a smaller touch-starved human, an isekai twist, size difference, and a possessive claiming.
