RMILD-585 - Lesbian experts' 4-hour relay, beautiful idols on the verge of fainting

I bought this thinking the woman who dominated in Rio Hamasaki's '4-Hour Orgasm' was a 'lesbian iron-woman' and wanted to see more of her, but it's just a compilation of random 'lesbian' scenes. Aside from Rio Hamasaki, whom I'd already seen, there wasn't anything particularly noteworthy.
