I had a physiological aversion to my father-in-law, but was unable to tell my husband. Suddenly, my husband was scheduled to go on a business trip and I had to spend the night alone with my father-in-law, so my bad feeling came true. My father-in-law pretended to be half-asleep when he came into my futon. My father-in-law, who usually spies on me when I have sex with my husband and knows everything about my body, stimulates my erogenous zones with the wet tip of his tongue, so I'm helplessly dominated by his tongue techniques.
