I have a secret that I can't tell my husband. It's about my relationship with my husband's son from his second marriage (my son-in-law). I didn't know how to treat my son, who suddenly started living with us, and I ended up just doing whatever he said, which I think was a mistake. My son became arrogant and looked down on me, and then... After that, whenever my husband went out and we were alone, my son started forcing me to do lewd things...
