``I want to have sex with my sister...someday, I started thinking that way...and finally...my rationality...collapsed.'' The younger brother's vulgar acts are exposed as he has the urge to make his sister his own, forces him to have a physical relationship with her, and pours his semen into her!




















The sibling dynamic just doesn't come through. I don't mind the scenes with other men or the masturbation, but they should have built up the sibling chemistry more before the final act; it just feels like forced sex. The sister's character is also just written as a promiscuous woman. She's not a stunning beauty, just looks like an average girl you'd see anywhere, which is a shame.
The fixed-camera style makes it feel like you're peeking in, which is great. Kudo-san is perfect as the older sister; it felt like watching real, raw footage.
She's pretty and acts well. However, her 'shivering' acting is clumsy, and you can clearly see her lifting her own hips, which makes it obvious it's just actingโthat's a shame. That said, in the bath scene, you can see her habit of cleaning up immediately after use (especially at the sink?), which gives the impression that she's very organized in her daily life. The plot involves blackmailing her into sex by threatening to leak hidden-camera footage of her online chats or encounters with acquaintances. It's good that the sister is sensitive, so she eventually stops resisting and starts wanting more. The setup involves wearing her sister's thong and finding the hidden-camera footage on her phone, but I wish the sex scenes were directed a bit more skillfully. Just cumming on her and ending it feels a bit lazy...
