DESCRIPTION

At the point when 23-year-old Hirose Anna discovers that her younger sibling strokes off with her grimy clothing, she chooses to make things a stride further by enabling him to see her do mischievous things too. Each time the circumstances heighten until the point when she turns out and reveals to him that as his elder sibling she will assume liability for his sexual interest. She enables him to do anything with her aside from legitimate sex; yet as his solicitations get dirtier each time, she stays resolved to assume liability and prop things up regardless.
