Mr./Ms. Chiharu is a school teacher and is teased for being called 'Big Pie Sensei'. She doesn't have a boyfriend, and she says, "I used to squirt so much that I was frustrated, and I have a complex about having big breasts ...", and she seems to have almost no experience. She is plain, but her face is beautiful, and her style when she takes it off is divine. Especially the milk is the best. Lewd.
