Her parents are very strict with a 5 PM curfew. I started dating Karina through a friend's introduction, but our dates were always at fancy cafes or art museums. I wanted to take things further with Karina, but her father always called to urge her to come home. One day, I was invited to her house and met her mother, Ayaha. Ayaha was a beautiful woman with mature sex appeal. However, Ayaha told me to break up with Karina, so I impulsively pushed her down... After that, Ayaha and I started having secret meetings right after Karina went home at 5 PM...
