IMAI-001 - The Depraved Brother: Selling Secret Footage of My Own Sister

I didn't think the masturbation scene in what I assume is her room was bad up to a point. It didn't feel overly forced, and she wasn't making a huge scene, which was fine. After that, the guy who seems to be her brother touches her while she's sleeping(?), but things progress way too easily. Even if it's not her first time, she should at least show some surprise—it makes you want to call out how unrealistic it is. After that, it just ends without anything special happening... the direction felt completely flat. Also, the way the condom just appears out of nowhere right after the oral sex felt really lazy.
