As my wife was about to give birth, my mother-in-law, Tina, came to Tokyo from her parents' home to support her. Thanks to Tina, my wife's burden was lightened, but on the other hand, it was causing me trouble. My wife had ordered me not to masturbate for a month, so I was desperately trying to control my sexual desire... Although I knew it was wrong, I couldn't help but stare at Tina's voluptuous body. What's more, I ended up peeking at Tina's naked body while she was taking a bath. As I was engrossed in Tina's naked body, she found out that I was peeking and asked, "Ren, you're looking, aren't you?"
