It's been 10 years since my mother passed away due to illness. My father, who raised me single-handedly, is remarrying. Her partner, Marina, is beautiful and kind... I can't believe that such a wonderful person will be my new mother. However, every time I sneaked a peek at Marina as she interacted with her father almost every night, I was surprised by the strength of her sexual desire and spent her days in agony. One day, when we were alone, I confessed that I had no experience, and Marina approached me with a smile... From the beginning to the end, my mother-in-law, who has a strong sexual desire and makes me cum over and over again without shaking her hips, had close-up raw sex with me until I lost my hips.
