Ai divorced her husband six months ago. After the divorce, she restarted the yoga classes she used to teach at home three months ago. Students gradually started coming through word of mouth. Most of them wanted special lessons with Ai. Ai felt lucky — her desires were being satisfied and she was also earning money. That day, she gave a yoga lesson to a young man who had come by referral. Ai casually touches the man's body. Even through his tracksuit you can see his penis getting larger. Gradually the special lesson between the man and Ai begins. Later, he returned with a regular male customer.
