Kamakiri no Ori 1 (onBLUE comics)

[Machine Translation] The pleasure instilled in him by a lonely sergeant. Ikuro, who has been brought up strictly as the heir to the Toma family, a prominent family in the Showa period, is deprived of all his father's attention by his concubine brother, Ranzo, who is sheltered in a tatami room. Despite the pain, Ikuro behaved stoutly, but there was always a man by his side. Norihiko. Norihiko is an older servant who has served Ikuro since he was a child. Norihiko loved the lonely Ikuro like a snake. He taught him to kiss deeply, forced him to open his legs while pretending that he was processing him sexually, and gouged his buttocks with his long fingers. In this way, he planted the seeds of pleasure in Ikuro, and transformed his body to become more and more desirable. A few years later, the situation changed drastically. The head of the Toma family dies, and it is time for Ikuro to take over...?
