MIDV-699 - I witnessed my sister masturbating alone in her room and lost my composure. I didn't realize my sister was aroused and she moved vigorously. Ishikawa Mio

*The story begins when an older brother witnesses his younger sister, a NEET mourner, masturbating. First of all, Mio-san, who played the delicate and quiet-looking mourning woman, was wonderful. And in the masturbation scene at the beginning, the feeling of him enjoying it for a long time was very naughty. The story of the erotic younger sister being turned on by her older brother's reckless behavior was erotic and exciting from start to finish. Even so, the sight of her masturbating from behind is naughty.

The brother taking his sister was good, but the follow-through was a bit disappointing. I thought he'd just keep going, but then the sister starts discovering her sexuality. It's not *bad*, but I would've preferred if the brother had turned her into his sex slave. Honestly, it needed a bit more of a dark edge.

Out of the four chapters, 2, 3, and 4 are all full-on nude interactions, which is great. Even chapter 1 ends with her only wearing a camisole, pulled up to her chest, so you can fully enjoy Mio-chan's beautiful body. No complaints, it was really good. Mio-chan in this work is just too cute, as always.

Ishikawa Mio makes her series debut as a highly-libidinous, shut-in younger sister. The story begins with her being caught masturbating by her brother while the family is away. The scene is interrupted by their parents' return, but once they're alone again, it progresses to a periscope-style blowjob in the bathroom, a subtle power struggle at the dinner table, and a nighttime bedroom scene. The beginning is structured with only moans and sighs for the first 20 minutes before dialogue is introduced. She appears in the classic “shut-in sister look” – a red tracksuit and round glasses – but the subtle details, like her nails being done, are also unique. The highlight is Mio’s growth as she “discovers true pleasure through her relationship with her brother, something she couldn’t find through masturbation.” It’s impressive how it goes beyond a simple taboo setting and emphasizes the changes in her emotions and their intimacy. With this release, Tsukigumo Yoru is slated to appear in the next installment, raising expectations for a series. I’d love to see a sequel with a lineup including Miyashita Reina, Tono Hanarin, and veterans like Nanazawa Mia and Yagi Nana. Ishikawa Mio has steadily grown into an ace performer in recent years, easily handling roles like “younger sister” and “girl with glasses.” Her perfect face and angelic cuteness are, as always, a perfect match for my tastes. This work is one that really lets you feel Mio’s charm and growth. Definitely a must-watch. I'm adding this to my collection.

There are three versions total, and the actress really showed her range, clearly differentiating between the more reserved first take and the really proactive third. She's a seriously talented performer. It's not the sweaty, messy type of scene, but the beastly expression she gives during the second, lying-down scene is *amazing*! The final monologue directly to the camera – you can tell it's a script that knows Ishikawa Mio is a stunning beauty. Definitely a keeper!
