For premature ejaculators across Japan. In this work, I visit the homes of those struggling with premature ejaculation and teach them muscle training, focusing on the muscles of the thighs. After the workout, I check to see if the premature ejaculation has been cured by vigorously stimulating their manhood. Of course, I also provide a fresh supply of protein (sperm). "Premature ejaculation can be cured with muscle training!" Believe it, girl.
