Buzama 2- Henka And Buzama Frontier -final- -en... Link -

As one review states: "本作は見事なまでに特殊性癖・特殊シチュエーションに特化したエロシーン" — "This work is a magnificent specialization in specific fetishes and situations". The "Henka" is not just a cosmetic change; it is the reward for failure, turning a losing state into entertainment.
