22-year-old I-cup beauty Yu Sasamoto (pseudonym), who is getting married in a few months, appears for the third time. She meets her followers for the first time through DMs on a social networking site she started without her fiancé's knowledge. Her erotic switch goes out of control, and as a result... she even voluntarily engages in bareback sex without a condom, something she had previously refused to do. This time, she may have woken up to something.
