My husband failed at work, and to pay off his debts, we moved into his father's house in the countryside and started living together. I didn't have a good impression of my father-in-law, who was a typical old-school chauvinist. However, to be honest, I was envious of the super-stamina sex that echoed every night. While he and my mother-in-law were still actively enjoying their married life, my husband and I were sexless, and with him always busy with work, my days were filled with sexual frustration. Gradually, I started masturbating alone to the sound of the pistoning echoing from my father-in-law's room. My father-in-law noticed this, and the next day at noon, in the sweaty summer heat, after finishing the housework, I was feeling restless and accidentally touched myself down there, only to be caught by him. "You're sexually frustrated, aren't you? I know." Everything started from there. Although I said I didn't want it, my body reacted honestly. With a sexual appetite like a teenager, I lost my sense of chastity and convulsed, panting at his magnificent, fully active, and throbbing cock. My husband always rushes through sex... but my father-in-law is different. He led me to an abyss of pleasure my husband had never reached, making me squirt massive amounts of juices that I usually never produce. I couldn't hold back anymore. Now, every night when I hear the sounds of my father-in-law and mother-in-law having sex, my pussy aches and drips with love juice. I'm sorry, I've had an affair.
