Yuna Inamoto, a modern college student. She applied for a psychology experiment part-time job to fund her graduation trip, but before she knew it, she became obsessed with a foreigner's penis and fell into becoming a bath girl at a foreigner-only soapland.












Ruka-jo's reactions are great. Is that her genuine reaction when the guy's huge member goes in? Just hearing her say 'It's so big' gives me goosebumps.
Ruka Inaba has been in so many routine works that she hasn't really been able to show her talent as an actress. In this one, whether it's the size or the fact that her partner is Black, she seems to be genuinely enjoying the act, and her reactions are so fresh.
The story is a bit questionable. A 'specimen' part-time job? Delirium? I think a standard, intense 1-on-1 soap play in a regular soapland would have been better. Please produce the next one with a white actor. I'm counting on you. See ya.
Inaba Ruka herself is fine, but her penis is dark, so the condom is way too obvious. You can even see the condom during oral sex, which is distracting.
心理学の実験協力者のアルバイトと称して、催●状態で、黒人とソープランドプレイで 快楽調教していき、もう外国人ペニスの虜になっちゃう見たいな流れで その夢か現実かわからぬままの状態の時は、快楽調教も無理やりでは無いので、嫌々感も 無く、珍しんパターンでこれはこれで悪くなかったが、催●を解くタイミングと夢と現実の境界線の解除のような区切りが全く無いまま最後に行き成り、外国人専用ソープの湯女に堕ちていく展開がちょっとイマイチだが、稲本ゆなの巨乳とエロ度は、黒人にも負けない存在感があるので、そこは良かった。
