After watching this work, I was completely overwhelmed by the overwhelming charm of the big-breasted sister squad! The intense scenarios woven by the four—Mashiro Koko, Kitagawa Riko, Akemi Miu, and Nanase Kokoro—truly embody a man's fantasy. Particularly, the handjob scene amid the tension of almost being caught by friends induces an excitement that makes you hold your breath. Mashiro Koko's nearly bursting cleavage is emphasized even when clothed, and her soft, jiggling large breasts after undressing are proof of the real deal! While her face might be a matter of taste, her voluptuous body and intense breast shaking are definitely worth seeing. Kitagawa Riko, with her youthful face yet full of sex appeal, excels in the lewdness of titty fucking and blowjobs. It's a pity she has few solo works, but her presence in this piece is top-notch, making me hope for more of her performances. Akemi Miu's transformation from handjobs with a devilish smile teasing erections to proactive sex is utterly sexy. Nanase Kokoro also holds her own as a big-breasted type, though she might leave a slightly lighter impression compared to the other three. The situations are varied overall, with attention to detail evident in scenes like the cleavage shots during clothed blowjobs and grinding in cowgirl position. However, the near absence of kissing scenes is personally disappointing; more intimate depictions would have scored higher. The price is a bit steep, but considering the four luxurious cast members and volume-packed content, it's well worth the cost. I have no regrets buying it and confidently recommend it as a masterpiece!
