Outside, it was pouring rain, and I was inside the cozy house comfortably watching a movie when there was a knock on the door. Thinking it was my mother returning, I hurried to open it, but in front of me stood a stranger, a woman drenched in thin clothes that made me see through to the alluring black bra she was wearing. It turned out she was Asakiri, my mother's best friend, who had stopped by to take shelter in her friend's house because she was caught in the heavy rain on her way home from work. After drying off, she began to sit on the sofa and asked me about adult matters, which made me very shy. She gradually moved closer and initiated physical contact with me, causing me to lie still, afraid to move. That night, she taught me how to make love.
