The center member of the underground idol unit 'Nitro☆Girl,' NANA-chan, is known for her proud large breasts and has been gaining attention through gravure activities. She is currently in high demand as an idol, but it turns out she has been secretly involved in a romantic relationship with a young fan! A middle-aged otaku father, enraged by this hidden betrayal, storms into the agency. 'If you don't want this to be leaked to the media, do as I say!' Even the timid manager agrees, leaving NANA no choice but to offer her body. The middle-aged man's sticky caresses squeeze and suck on the idol's large breasts, performing semen-filled sex. This alone does not satisfy his anger, so he organizes a vagina photo shoot event in front of fans, an otaku group sex where she is made to suck dicks, and fills the idol's vagina with otaku semen until she becomes pregnant.
