Soon after getting married, my husband went on a business trip alone for three months. Worried about me living by myself, my sister and her husband let me live with them, and I spent peaceful days... But sexual frustration built up day by day, and I released it through masturbation every day. One day, I found out that my brother-in-law Tetsuya was also suffering from a sexless life... Moreover, he had an unusually large penis that he couldn't handle, and unable to control the desires of my flesh, I secretly tempted him. Then, unable to resist my little devil's temptation, Tetsuya ended up having a relationship with me...
