When she was a student, Mitsumi had many "relationships". She was even called a "whore" by others. But since getting married, she has completely changed. She married a gentle, kind husband and became a full-time housewife. Mitsumi enjoys the most peaceful period of her life. However, everything was disrupted when her husband had to go on a business trip far away. He had said he would come home once a month, but now because of work, he can only come home once a year. During the time her husband is away, Mitsumi's sexual desire has reached its limit. At that moment, her sister-in-law's family went on a trip, and because she wanted Kazu-kun to continue studying, she asked Mitsumi to look after the boy for a few days. Indeed, the little boy is diligent; as soon as he arrived at the house, he rushed to study immediately. Since Mitsumi is quite young, the boy wanted to call her "sister," and Mitsumi happily agreed. With her desire reaching its peak, Mitsumi suddenly had a bold thought... Seduce this naïve nephew to satisfy her sexual cravings! Thinking of doing it, Mitsumi deliberately exposed his underwear in front of Kazu, but the boy just looked at it and did nothing. Next, she even took off her underwear, revealing her "mysterious stream" in front of her nephew. But the results still did not yield anything. For one thing, she succeeded in making the immature "eyelash" raise her head. In the evening, she is determined to get Kazu's virginity, quietly go into the room and seduce him! Mitsumi's plan succeeded, only she woke up the sex monster inside Kazu! He wasn't satisfied with just once, ejaculating over and over again, Kazu didn't even want to wear a condom, constantly ejaculating all his "seeds" inside his lewd aunt!
