I love Rio Hamasaki and Kokomi Naruse, so I bought this without hesitation. My only complaint is that the runtime is too short. I wanted to see more of the interactions with each person, and it would have been perfect if it had featured 3P with different combinations, ending with a 4P. All three of them were so charming that it felt like it was over in a flash. My personal 'Little Sister -1 Grand Prix' winner was Rio, but I hope you find your own No. 1.
Mizuki Ishikawa and Kokomi Naruse were great, of course, but I think the star of this 'Little Sister-1 Grand Prix' is Rio Hamasaki. Also, I was so jealous watching the three of them fighting over the dick during the 4P scene.
The premise is great, but the cast is absolutely outstanding! Rio Hamasaki, who is playful, sexy, and busty. Mizuki Ishikawa with that loli appeal. Kokomi Naruse, who is cute with a touch of maturity. However, a couple of downsides: the beginning felt a bit too drawn out, and I was hoping for one round with each girl followed by a final group scene with all four. Instead, the other two barged in during Kokomi Naruse's part, which made that section feel a bit incomplete. That was a shame. Still, overall satisfaction is very high.
Rio Hamasaki. This actress is perfectly suited for incest themes. She skillfully draws you in by begging for forgiveness, confessing her feelings for her brother, and transitioning into sex with a spoiled, needy demeanor. She makes great use of her school uniform, writhing her voluptuous body in ecstasy under her brother's touch. Mizuki creates a sisterly vibe with her husky, spoiled voice, but her reactions are a bit lackluster. Kokomi, with her innocent and lisping voice, is compelling as she furrows her brow and endures her brother's advances with cute whimpers. In the final 4P scene, they mostly just envy the others being touched by their brother rather than actively interfering, so the intensity of the competition is somewhat low.
I like all three actresses, so I enjoyed this one. Honestly, I thought Rio Hamasaki might be a stretch for a 'little sister' role since she's quite mature for her age and has an older-looking face, but she was actually really cute. Especially when she first appeared in a tank top—I was genuinely surprised by how cute she looked. As for Mizuki Ishikawa, she's not exactly known for her face. I think her selling point is her figure rather than her looks, so I was a bit disappointed that she stayed clothed for so long. Personally, Kokomi Naruse's 'little sister' role hit the spot for me. She has a great body and a decent face, but she usually feels like something is missing. However, she played the cute little sister role perfectly here. Compared to the previous installment, which lacked that 'little sister' vibe, I think this one is quite satisfying.
