Hidden camera footage of busy office ladies visiting a private soundproof room called "Hitokara" during their lunch break. Unaware that they are being filmed, they are given drinks mixed with aphrodisiacs by their targeted customers, inducing masturbation, and the entire process is secretly recorded. The sense of security in a supposedly soundproof, single-use room, combined with the possibility of the staff suddenly opening the door and the shadows and footsteps... a mix of liberation and thrill... A large amount of hidden camera footage of beautiful office ladies engaging in bold masturbation due to the overdose of aphrodisiacs!
