厳格なりし熟牝教頭の性育教室

Himejima Academy is a school for only the very best and brightest -- that includes the teachers, too. Mayumi Kurose spent a year teaching at this elite school, but now she's back as our vice principal. She picked up something during her year away, however... a new, more hands-on style of sexual education. But will things go according to her syllabus? Or is this class about to get a LOT more educational? [From DLsite]
