This was a bitch to get an image hit on, google was useless but tineye eventually founf one result with the fence scene.
It might be something called "After Class Lesson no Sasayaki". I can't find those exact scenes at a glance, but the green fence wire pattern and lower blue wall under it match perfectly in other scenes.
It is a hentai, so odds are it's right.
