My daughter's friend comes to a sleepover to study for a test. But instead of studying, the topic of the sleepover party was ``How do you do Chew?'' Even my best-achieving daughter secretly asks my father about this question, and I have no choice but to show him my treasured erotic books, and he peruses them with great interest.

My daughter's friend comes to stay at our house and study before the test. But in reality, things end up being exciting with naughty girl talk. Moreover, there are many things that these immature girls do not understand. That's why I, as a father, ask this question... As a desperate measure, I showed him an erotic book I owned as a reference book, and his erotic curiosity was ignited, leading to a serious situation!
