MKON-038 - My idol girlfriend's secret life, caught by a perverted teacher... Urara Hanaon

First off, the gap between Urara-chan's loli face and the thick hair down there is moe. Her physique fits the loli trope, and the plot—an idol caught by a creepy teacher—is classic. The actor playing the teacher is incredibly good at being creepy. She gets gang-raped at the end, but I wish she had just been taken by that one actor until the finish. Still, a perfect 10/10.
