To bring the trio back together, Airu makes a deal with her manager who secretly runs a sex bar - if she can resist his advances, he’ll convince Maika to return to her normal life. Too bad there’s no way Airu can win against his giant cock.

As a reward for her commitment to break her boyfriend, Airu goes on a cheating hot springs trip with her manager. He intends to make it wholesome, but Airu is too horny for a peaceful date. Back at home, Airu successfully makes her boyfriend, Daiki, more possessive over her, but it unexpectedly brings out his manly side. What will the manager think if she can’t break him like she promised…?
