Yuka, a girl who suffers from social isolation at school, has a secret: she is an online erotic streaming star, concealing her identity with a mask. One day, she finds what appears to be a love letter in her locker, but it actually contains screenshots from her streams. The man behind the letter blackmails her, threatening to expose her identity unless she complies with his demands.

After being fucked, Yuka can no longer find satisfaction through masturbation during her sexual streams. Her blackmailer summons her again, this time to his home, and she arrives determined to delete the incriminating video. However, upon feeling the man’s touch, Yuka experiences an overwhelming mix of anticipation and pleasure. Forced to engage in more extreme sexual acts than those in her streams, her body responds with heightened sensitivity, gradually leading her to embrace the man in a natural and sensual way.
