My husband and I have fallen into a sexless marriage. We used to passionately make love every single day when we first got married, but lately he constantly turns me down, saying he's too tired from work. I've always had extremely strong sexual desires, and living without sex has become unbearable. I decided I had to find a way to get my hands on a cock. That's when I discovered my father-in-law secretly watching me masturbate through a crack in the door. Despite his serious and innocent demeanor, this unexpected, adorable side of him instantly attracted me. My husband is still living in the house, but as long as he doesn't find out, it should be fine. Under these circumstances, I decided to start enjoying a secret relationship with him.
