SGKI-039 Himari Kosaka, the busty beauty who wants to be a costume star and remains unresponsive no matter how much she is penetrated

Himari Kosaka (21 years old), a new actor/theater troupe member, is in her first year and is fascinated by costumed actors. What is a costumed actor, who must never make a sound? "I don't make a sound because I want to protect the character of the costume I'm wearing, and I try to act like the character." This is an intimate documentary of the sweat and tears of a costumed star who hangs on to strict training and dreams of becoming a costumed star. She uses an electric massager to train herself to hold back her voice, and appears at events while inserting a remote vibrator! The final test is a costumed 4P sex with no reaction. Will Himari's dream come true?
