Aneki no Kounai Kaikinbi

When Hirose Anna, 23, discovers that her younger brother masturbates in her filthy underwear, she decides to go one step further and let him witness her doing nasty things as well. Each time, the issue becomes worse until she comes out and informs him that she would take responsibility for his sexual interest as his older sister. She lets him do whatever he wants with her except have good intercourse with her, but she remains determined to take responsibility and keep things going no matter what.
