Description:

Twins Izuru and Kokone harbor a deep love for their elder brother, but only Izuru has acted upon her feelings so far. When she arrives home from school, Izuru often goes directly to her brother’s side and indulges in him. Unlike her proactive sister, Kokone merely watches them from the side while drowning in jealousy. All she can do is pleasure herself to the sound of their salacious acts.
