OBA-314 Michika Yagi, an aunt who fascinates us

I’m currently a preparatory school student for 2 Nami. I tried to pass it on my own, but it didn’t work, so I decided to move to Tokyo and live in a boarding house. In this boarding house, there is an implicit rule that only those selected by Aunt Michika, the caretaker, can participate in the special training at midnight. The content of the course can only be understood by those who participated, but it seems that nosebleeds will occur just by imagining that the course is a course alone with Aunt Michika with huge breasts. However, on the first day of the boarding house, I heard a moan from the room where the class was held, contrary to my imagination.. OBA-314 Michika Yagi, an aunt who fascinates us
