【Story】

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…

【Game Description】
