IESP-676 Suzu Monami: Lesbian Unleashed - I Fell In Love With My Step-sister

My older sister Suzu and my younger sister were separated when their parents divorced when they were young. A few years later, her father passed away, so she was forced to live with Kotone again. One day, when Suzu is doing her daily masturbation, she is witnessed at the scene. She was happy that her older sister also liked masturbation, and when they overlapped each other's lips, they invited them to the forbidden lesbian world.
