Get ready for the 4th Sister-1 Grand Prix! Featuring three adorable high school sisters with different personalities—clingy, shy, and tsundere. All of them are gorgeous and busty, and the POV camera makes you feel like you're actually there.




















This is the 4th installment of Deeps' 'High School Girl! Little Sister-1 Grand Prix' series. Compared to the 2nd installment featuring charismatic gal actress Rina Aina or the 3rd with AV queen Rio Hamasaki, it's hard to deny a slight 'lack of a main star.' However, the cast is an 'impenetrable' dream team for breast lovers, featuring 'explosive breasts' (Neiro Suzuka), 'huge breasts' (Chisa Hoshijima), and 'beautiful breasts' (Aya Hirai). Every 'little sister' is great, but Chisa, who plays the 'post-bath little sister,' is the most 'moe' of them all, helped by the perfect situation. By the way, after the main scene with Chisa, the other two crash the set, shifting the film into 'harem mode.' That said, the actual intercourse only involves Chisa, so if you aren't a fan of hers, the progression might leave you a bit unsatisfied.
I bought this because I liked the actress from the previous installment, but I didn't really enjoy it. It's a shame there wasn't an actress with as much personality as Rio-chan. I think it would have been better if they had utilized Neiro-chan more effectively. However, for those who like the 'little sister' trope, it might be worth a watch since they portrayed that dynamic quite well.
I had high expectations when I rented this, but it was a letdown. The previous entry featuring Rio Hamasaki and the other two girls was so good that I couldn't help but compare this one, given how similar the structure is. It's a series with a lot of strong points—the POV-style camerawork, the actresses' natural solo performances, the 4-way scene at the end, and the cute, busty cast—so I'm looking forward to the fifth installment.
