A virgin brother gets teased by his little sister who loves toying with his erection.












It's a lighthearted comedy about siblings, but... hmm, it feels like it misses the mark in so many ways, which is such a shame. Tsumugi-chan, the little sister, is both cute and beautiful, but her charm was completely wasted. The story follows Tsumugi, who loves her timid older brother, as she films an 'Onii-chan Log' over the course of a month, observing him and doing lewd things together. The setup of her being a little devil and teasing him—because he has to be flustered, that's what makes him cute!—was good, but the direction failed to execute it, and the sibling dynamic felt weak. As other reviewers have pointed out, the brother is... how should I put it... pretty cringey. His lines to Tsumugi aren't necessarily wrong, but it's like he doesn't understand how to act flustered or shy, or maybe he's just incapable of it. It's frustrating to watch because there were so many better ways to build the tension. The structure and pacing are also very unnatural, and for a comedy, the sense of humor feels off. The plot is so unrealistically extreme that it feels like they thought as long as there's an H-scene, they can ignore the details, which made it impossible for me to get invested. However, despite how boring the content is, Tsumugi-chan is consistently adorable, which is truly impressive. The sibling H-scene in the middle is so cute it's actually healing. From her expression waiting for a kiss (1:07-8) saying, 'How about a kiss, Onii-chan?', to French kissing him and saying, 'You're having such a lewd kiss with your little sister, Onii-chan,' and then happily exclaiming, 'You're having sex with your little sister, Onii-chan!' (1:12). When her brother gets excited and calls her 'Tsumugi,' she gets angry and says, 'Don't call me by my first name!' (1:28). This whole sequence is dangerously cute. Even without any real substance, just watching Tsumugi-chan was healing. I guess cute girls have the power to make people happy just by existing. Maybe because the work failed to utilize her sparkling charm, it actually made her appeal stand out even more. Tsumugi-chan is the kind of girl any woman would admire... she was wonderful.
The content is actually quite interesting, though it's not really my cup of tea. Tsumugi-chan worked really hard and was fantastic, but that male actor was a terrible choice for this production.
This one isn't very erotic. You know what? Maybe I'll just blame the male actor!
It's a work that draws you in not just with her cuteness, but with her expressions and voice. She only goes fully nude at the very end (and even then, she's wearing high socks), but the situations leading up to that are very enjoyable.
Little devil vibes are the best. Her slightly ditzy way of talking is great, and the way she takes the lead is also amazing...
