21-year-old Misaki Mai plays the role of a daughter working a tough job as a customer complaint handler at a mobile phone company. Struggling to make ends meet from her call center salary alone, she decided to participate due to financial hardship—stepping into what feels like Japan's underground world. She currently has a boyfriend, but hasn't had sex in over a month. When asked about their relationship, she reveals that foreplay is too short and penetration hurts. In fact, she openly admits she doesn't enjoy sex with him. Despite her boyfriend being poorly endowed, she still finds it painful—an evaluation that reflects his terrible technique, leaving her utterly unimpressed. With only two sexual partners in her life, it's clear she's truly doing this out of necessity. Her speech lacks any sense of experience, coming across completely natural, as if it's her first time. Her bright face and cheerful manner of speaking are the only redeeming factors—had she arrived with a gloomy expression or aura, the scene would simply be tragic. She gets aroused, and when asked if she's really okay with this, she responds with a smile. But then suddenly turns serious. Of course she's nervous—anyone would be. Yet it's precisely this anxiety transforming into eroticism that makes her so alluring. Her sexual experience has been shallow, leaving her body still undeveloped. Her breasts feel almost unresponsive, her body lacking any real stimulation—like a virgin untouched by pleasure. The one saving grace is that she doesn't overthink it, staying quiet and still. But gently caressing her ears? That triggers an astonishing reaction! Whoa, she's already getting turned on. Let's start right here. We'll make her feel such intense pleasure that she'll never want to go back to her boyfriend again—this professional is going to make her climax like never before!
