Since her mother-in-law passed away, Mika's father-in-law became depressed. Concerned for her father-in-law, her husband brought him to live together with the two of them. However, her father-in-law did not improve, just sitting in his room and not eating or drinking anything. Today, Mika's husband had to go on a business trip, leaving her alone at home to take care of her father-in-law. It had been a long time since she had been intimate, and her desire was overwhelming, so she could only masturbate to relieve her own desires. Coincidentally, her father-in-law walked by and discovered her. Feeling too lonely, he couldn't control himself. "Just 10 seconds, can I put it in, my dear?" Without waiting for Mika's consent, her father-in-law immediately inserted his penis deep inside her. Exactly 10 seconds later, he stopped. The next morning, not knowing how to face her father-in-law, Mika decided to go out to pass the time. Suddenly, she found that breakfast had been eaten, and her father-in-law appeared in a better mood, no longer as despondent as before. Knowing that her daughter-in-law was also lonely like him, he wanted to satisfy her sexual desires. Despite initially refusing, their bodies strangely matched, the pleasure from each thrust of her father-in-law made Mika gradually forget all feelings of guilt. The two seemed destined for each other. And of course, her father-in-law continued to ejaculate deep inside her. Some time later, Mika became pregnant, and her husband was extremely happy upon hearing the news, showering her with affection and hosting a celebration. But Mika knew, the child in her womb was not her husband's...!!!
