This is the first of a side story multi-work series depicting Akiomi's older sister and older brother.

I dread going home, because at home... my cute little sister Sayuki is waiting for me.

If I come home, days when my younger sister will provide me sexual relief for the purpose of getting pocket money will begin. This kind of relationship started when my sister accidentally sent me a message that shockingly revealed she was engaging in compensated dating with sugar daddies...

This is a story about an older brother getting squeezed out in more ways than one by his morally bankrupt biological sister.
