I live happily with my husband and my father-in-law. I'm not particularly dissatisfied with our sex life, but one night my vagina tingles for some reason. I masturbate in the bathroom. My father-in-law happens to see me doing this and has a hold on my weakness, and now he licks my whole body every day. My body, which I didn't like being licked, has been completely stained by my father-in-law.
