When she was a student, Mitsumi had many relationships. She was even called a slut by others. But since getting married, she has completely changed. She started a family with a gentle, kind husband and became a full-time housewife. Mitsumi enjoyed the most peaceful period of her life. However, everything was disrupted when her husband had to go on a trip far away. Previously, he told her he would come home once a month, but because of work, now he can only come back once a year. During her husband's absence, Mitsumi's sexual desire reached its limit. At this moment, her sister-in-law's family went on vacation, and wanting Kazu-kun to continue his studies, she asked Mitsumi to look after the boy for a few days. Indeed, the little boy was diligent; as soon as he arrived home, he dove right into his studies. Since Mitsumi is quite young, the boy wanted to call her sister, and Mitsumi happily agreed. Because the desire had reached its limit, 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 artist 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, repeatedly ejaculating all his seeds inside his lewd aunt.
