MUCD-225 - 巨尻少女と体操服 4時間 ブルマ姿で真ん丸のおっきなおっきなお尻を揺らしながら絶頂しまくる巨尻少女12人 4時間

I think this is the tail end of the bloomers generation; these were the bloomers from my middle school days. It's a strange style looking back now, but there's a certain male romance associated with bloomers. I bought this to enjoy seeing Riko Kitagawa and Makoto Takeuchi in bloomers. Since it's more of a digest-style work, it's best to use this to check out your favorites and then look for their individual full-length titles.
