START-177 - A story of being comforted by a slovenly older sister, Koibuchi Momona

Like others have mentioned in the reviews, hearing the actor's inner thoughts during the action is a bit distracting. It feels like noise in an AV context. I think it's a result of prioritizing the source material, but other than that, Momona-san's portrayal of Hana's body is just perfect. Absolutely stunning. I recommend this even to people who haven't read the original manga. Definitely a keeper!

The initial atmosphere was fantastic. It felt so real, not too close or too distant, and the 'neighbor' setting just clicked. Mona-san's body is a given, but the fact that she didn't push the eroticism too hard at the beginning was actually a brilliant move. The flow was natural, her words and actions were gentle, but the way she gradually changed how she touched him was incredibly erotic. I loved the loose, languid atmosphere and how her body just became honest. The pressure of her chest when she leaned in and how she filled my vision were intense – I felt trapped. It reminded me of when I tried coital orgasms before. From the middle on, the other person started wanting more, and the atmosphere shifted to pure eroticism. The change in mood was clear. It wasn't a flashy domination, but the tension remained consistently high, leaving a lingering afterglow long after I finished watching. The 'lazy older sister' trope is executed so well here. This is a masterpiece, honestly.

For 2D works, accurately recreating the world is key, and Momona-chan nailed it. I was so glad she challenged herself with doggy style (was that fantasy-based?). As a fan, if she's going to do doggy style, I'd love to see a scene of her doing it as her usual self, without the glasses.

The problem is… the male actor's acting is just too slick. Ugh. I keep telling myself it's unavoidable since it's based on a manga, but I get this urge that the guy should just shut up and *be* the tool, you know?

This style transcends 2D! And she really pulls off the glasses... Demure glasses, voluptuous Momona – she's the best. Seriously a masterpiece.
