After failing college entrance exams twice, I had no choice but to move to Tokyo and live in a boarding house. The landlady, Michika Obasan, has an unspoken rule: only select students are invited to her late-night private tutoring sessions. What exactly happens in these sessions remains a mystery—known only to those who've attended. But one thing's for sure: being alone with the busty, mature Michika Obasan is enough to make anyone's heart race. On my first night, I heard moaning coming from the room where a session was taking place, leaving me both curious and aroused, wondering just what kind of "teaching" goes on behind closed doors.
