This is a stealth-based adult simulation game where you follow the mysterious woman, Mio, and interact with her to uncover her secrets. As a professional trainer, you will fulfill Mio’s unique desires while gradually revealing the hidden story between the two of you.

One day, as an expert Sex Trainer, you receive a commission that defies all expectations. A client with a sweet, breathy voice whispers a shocking request: “Could you… please stalk me home?” It is an unheard-of request, but face-to-face with the ultimate temptation of breaking in such a beauty, how could a professional say no? Rock-hard and ready for action, you head straight to the convenience store where she works to see exactly what you’re dealing with…
