Принадлежащий:Nonoka, a girl who is more interested in naughty things than studying, has an older brother who stays at home all the time and spies on her younger sister masturbating or bringing her boyfriend along for sex. There is. One day, the perverted older brother sneaked into Nonokas room and went there night after night.He failed in the night, and from that day on, the power relationship reversed and the idiot older brother turned into a servant. Since then, he has been treated as a butter dog. Theyre both the same, but I guess you could say theres an older brother and a younger sister.
