The inside of a white coat is shown only to me. A big-breasted public health teacher in an extreme swimsuit seduces me into having sex with me even when I can't make a sound.

One day, he sprains his foot and visits the infirmary. Waiting for him there is Riho, a health teacher who is beautiful but somehow gives off a dangerous aura.

Today as well, when Riho-sensei takes off her white coat, the creampie instruction begins...! !
