Two people alone in an apartment: older sister Nanako and younger sister Kaoru. A night when their parents aren't home… TANP-034

Nanako, a beautiful older sister with a shadow in her heart, and Kaoru, a younger sister who dreams of becoming a boy, engage in dangerous sexual games during the day in an apartment somewhere—a summer love story. They enjoy themselves when their parents aren't around. After showering together, they perform oral sex. Then comes the sisters' self-appreciation of masturbation. Finally, they have unprotected sex with an uncle who likes boys. The uncle tells the sisters, "Don't tell Mom and Dad what happened today." Then he gives the sisters pocket money and runs away.
