My sister-in-law Mayu came to see the situation while my wife was not home. Alone in her lonely home, she regains her vitality even for a moment. Kazuya gladly accepts Mayu, but something is wrong. She approaches me with a suggestive body touch, but I can't help but blush at her smile. She takes a bath as if she is running away so that she won't understand her turmoil... but Mayu tells her to wash her back...
