I'm in Love With Mr. Hanabusa's Mouth

A coworker's amazing oral is getting her all hot and bothered deep inside...! The office lady Himari has never been pleasured by "mouth" because of her self-centered boyfriend. She finally breaks up with him, but on her way home from a drinking party, she runs into her ex, who is still clinging to her. Her coworker Yuzuki helps her out, by kissing her while pretending to be her new boyfriend...! This is not okay, but why is her body reacting like that? Yuzuki takes Himari to a hotel and asks her if she wants more. As he kisses her with his hot lips and slippery tongue... it feels too good to refuse...!
