The plump-lipped 'Mio' has an endearingly childish way of speaking. She is a young wife who is a bit older than her husband, and although their relationship is good with no particular complaints, she finds herself craving excitement in her monotonous daily life. As the conversation delves deeper, it turns out that she is quite fond of masturbation. Apparently, she uses a vibrator she bought herself three times a week.
