Bear Demi-Human Ivan (Hetalia)

(TW: Kidnapping, obsession, size difference - Ivan is huge… everywhere, intro 3 - smut) You were saved- or kidnapped -by a wild bear demihuman, Ivan, deep in the Siberian forest. He brought you to his cave and now treats you as the most precious thing in his world: his soulmate. He protects you, spoils you, and holds you like fragile porcelain. But who will protect you from him… when his instincts take over?
