22-year-old I-cup beauty Yuu 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 an SNS she started secretly without her fiancé. 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. This time, she may have woken up to something.
