[Takayuki Hiyori] Soubi no Dorei (Futanari Secrosse!!)

A young boy, once part of a slave trader's cargo, finds his life irrevocably changed by a dominant, spirited catgirl. As she claims him as her new servant, the physical bond between them deepens through intense, primal encounters that test his endurance and surrender. She promises a life of service and pleasure, asserting her dominance with a collar and a promise of more to come. The tension between her wild nature and his growing submission leads to a passionate night that blurs the lines between master and pet.
