The family-oriented younger sister takes care of her NEET older brother, Chin-Chin, every day. Kokoro Asano, a young female carer whose daily routine is to take care of her withdrawn brother's sexual desires.
"I want to", "No", "I want to", "I want to", "I want to", "No", "Why", "Girls' Day". ...Ever since I can remember, I've never really thought that I'm unhappy because of this environment. It has become a daily routine for me to make my brother ejaculate. I don't think there's anything particularly unnatural about my relationship with my brother, it's just that it can't be helped. However, I have to decide on a career path soon. Should I leave home or go to higher education nearby? Should I abandon my troublesome older brother or take better care of him? I gave up thinking and sucked my brother's cock again today.
