I hadn't been to my wife's parents' house for several years after my father-in-law passed away, but I recently returned because of my wife's class reunion. - My mother-in-law, Saori, was happy to see us return home. - That night, when I took a bath, I noticed that there was no body soap, so I asked my wife to get some from the bathtub. - While I was waiting, the door opened and it was my mother-in-law! - My mother-in-law smiles as she refills the bottle and washes it off my back. - I was hesitant and refused, but I gave in to my mother-in-law's push and decided to let her go. - My mother-in-law said that she wanted to see her grandchildren, but there was a moment of silence when she mentioned that she hadn't had any sex with her wife in the past year. - My mother-in-law had told me to wash it before, and I felt embarrassed because I had an erection, but she told me that she was fine with me, since she wasn't my daughter, and I said yes. - My stepmother gently squeezed his hard erection and licked it to taste it. - Unbearably, I kissed my mother-in-law's pussy as well, and spilled all of my accumulated semen onto her. - When I felt refreshed, he whispered, ``It's a secret between just the two of us, right? Today is special.'' - I was completely infatuated with my mother-in-law and couldn't sleep that night...
