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 introduced himself as 'Sperm Royal Master' (nicknamed Ikaroi). Ikaroi said that for Noka to be able to produce a loud voice, she needs an 'orgasmic experience.' For the inexperienced Noka, he clearly and specifically guides her on how to heighten excitement and naturally reach the peak. Although Noka felt extremely embarrassed to expose herself naked in front of her trusted manager, she quickly squirted profusely and reached orgasm. With meticulous fingering and cunnilingus, her body heated up, and along with screams-like moans that she had never made before, she seemed to part ways with her lack of confidence. Afterwards, Noka full of motivation expressed her gratitude to her manager through service... This is an extremely intense sex drama and a 'How To' work in the form of a let's play video where you can learn Ikaroi's thorough and meticulous techniques.
