The complete record of a busty student brainwashed for three years until she fell into a facial pet, Shitara Yuuhi.

Shitara Yuuhi moves to a new school and struggles to fit in. Lucky for her, her kind homeroom teacher takes her under his wing and shows her around with great kindness. They bond over a shared interest in novels, leading teacher Yoshino to invite Shitara to visit his home. There, the relationship becomes inappropriate turn as they end up having sex. Yuuhi develops a strong crush on the teacher, and the teacher gets hooked up on unloading sticky semen on her face, to which she always agrees. No doubt, this is a strong dose of Shitara Yuuhi… in the face.
