Why Are You Touching Me There, Mr. Kitamura? Sex-Ed With a Naive Country Girl

"Does everyone... really... do this sort of thing...?" I'm Haruki, a teacher who moved to start a new job at a school on an isolated island where the population is continuing to decrease. There, I met Chie, the oldest student in the school. Her big boobs jiggled... and on top of that, I could see her nipples poking through her gym clothes...! She lives alone with her grandfather and she has never stepped a single foot off of the island, so she didn't even know about bras. And so, I took it upon myself to teach her directly about how to put on an I-cup bra. Trusting what I told her since I was her, Chie responded sensitively as I played with her boobs and pinched her nipples. I couldn't control myself... and started sucking on her hard nipples! "Next, will you try... opening your legs?" As her teacher, it's my responsibility to give this naive girl some thorough instruction...!
