My brother, who was supposed to live with his younger brother and his wife, hated their marital life. One day, my older brother came up with the idea of monitoring his younger brother's wife and started voyeurizing his daily life. While monitoring, I found out that my brother-in-law Kurumi was chatting. Hiding her identity, she converses with Kurumi, and she learns that Kurumi is not happy with her marital life. One day when her brother wasn't around, she called Kurumi and told her that she knew from her chat conversation that she wasn't good enough, and she fucked him. She knew what Kurumi wanted her to do. Kurumi was immersed in the afterglow of her pleasure.
