In a country facing severe declining birthrates and an aging population, a new profession has emerged: the "sex educator."

Sex educators have the vital role of teaching proper sexual knowledge through practical, real-life experiences to inexperienced young boys and girls. The primary objective is to develop their erogenous zones from an early age.

By learning correct sexual knowledge and experiencing the joy of pleasure young children will naturally grow interested in sex, helping to reverse the declining birthrate trend.

The protagonist, Tomoya, takes on the role of sex educator assigned to train the erogenous zones of a young girl named Mitsuki.

As Tomoya, your mission is to guide Mitsuki in discovering and enjoying the pleasures of her still-developing body through intimate, hands-on lessons.

The game is an interactive touching simulation featuring smooth Live2D animations, voiced performances, and innovative 3D squirting effects for immersive adult lessons.
