My mother is afraid of water and can't take a bath, so I, her son, lick her body with my tongue every day to keep her clean. (Yui Hatano MRSS-170)

My mother nearly drowned in the sea last summer, which instilled in her a fear of water. She was so afraid of water that she dared not bathe or wash her face, so I licked her entire body to clean her. Then one day, while I was licking her, she suddenly became sexually aroused and asked me if I wanted to have sex with her. As a result, we engaged in forbidden sexual intercourse.
