[Sakurama Haruomi] Succubus Kingdom Ch.1 [biribiri]

Six Sins is an eccentric kingdom in the demon realm where the Succubus Queen has built a civilization that manages its human prey through breeding villages and slave auctions to secure a steady supply of essence. A busty, horned succubus with soft, heavy breasts and a possessive sweetness claims a delicate, naive femboy whose youthful, arched cock fascinates the crowd, sealing him as her own with a magical heart stamp that prevents any other demon from touching him. Her tender yet hungry devotion promises blissful daily lessons as she presses him between her ample chest and guides his innocent body to feed her mouth and pussy.
