The older brother, who was to live with his younger brother and his wife, was ignorant of their marital life. - One day his brother comes up with the idea of watching his younger brothers wife and begins to voyeur his daily life. - While watching, I found out that my younger brother, Kurumi, was chatting. - As she hides her identity and talks to Kurumi, she finds out that Kurumi is not happy with her marital life. - One day without her brother, she called Kurumi and she told her that she knew she wasnt satisfied from her chat conversation, and she committed. - Even though she said she had committed, she knew what Kurumi wanted her to do. - Kurumi nodded happily when she said, Ill play again, to Kurumi, who was immersed in the afterglow of her pleasure.
