After losing his father, Takumi lives alone with his mother, Ayaka. Ayaka is nothing like a mother should be—always elegant and refined, and every time I saw her, my heart raced. One afternoon, I visited Takumi's house to return a borrowed game, but no one was home. Peeking around the back, I spotted Ayaka through the glass window. Mesmerized, I kept watching until she started relaxing alone—and I couldn't hold back any longer. I climbed in and pinned her down.
