MKON-130 A 30-something NEET with low self-esteem, former honor student sister-in-law Kasumi Tsukino

During the holiday, Fuk returned home. His sister-in-law Kasumi, who used to be an honor student and worked at a major corporation, had been a recluse since she fell ill from overwork. The family suggested treatment, but Fuk felt that she had broken down because she was forced to act. One day, she suddenly said, 'I can't do anything. I'm sorry for being such a sister-in-law.' Fuku sees Kasumi's vacant expression and thinks, "If I leave her alone, she might die." He desperately starts thinking about how to give his sister-in-law a reason to live. "There isn't much I can do for Fuku, but if there's anything, just say the word..." she says. So Fuku says, "I want to see your tits." Conflident Conya says, "My naked body isn't worth anything..." But Fukushiro denies it and bites her tits...
