An elegant woman named Mirin, encountered around Nishi-Shinjuku Station. Her soft, wavy brown hair gives off a gyaru vibe at first glance, but she speaks politely and comes across as intelligent. At 30 years old, she works as an esthetician around Shinjuku, and her job keeps her skin flawless—an undeniable charm. Her hobby is baking, and she occasionally brings homemade desserts to her boyfriend. They've been together for about a year, but both have grown busy with work, reducing their meetups and leaving her looking somewhat lonely. They used to see each other once a week, but now once a month is all they manage. Naturally, their sex life has declined too. And that’s exactly what created this opportunity. Her horny side begins to show—easily tempted, she exposes her gorgeous big tits, and with a little more coaxing, even allows penetration. Indeed, Mirin has a deeply lustful side waiting to be awakened.
