New voice actress Sato Noka has a soft voice and is on a losing streak in auditions. Her troubled manager visited the home of a man who calls himself 'Sperm Royal Master' (nicknamed 'Sperm Roy'). Sperm Roy says that for Noka to be able to produce a loud voice, she needs an experience of 'reaching orgasm.' For the inexperienced Noka, he clearly and specifically teaches methods to naturally heighten her excitement and guide her to the peak. Despite feeling embarrassed about exposing herself naked in front of her trusted manager, Noka quickly gushes profusely and reaches climax. With meticulous fingering and cunnilingus, her body heats up, and she lets out screams-like moans that she has never made before, seemingly parting ways with her lack of confidence. Afterwards, filled with motivation, Noka expresses her gratitude to her manager through service... This is an extremely intense sex drama where you can learn Sperm Roy's meticulous techniques like a game commentary video.
