MCSR-324 - お母さんといっしょ2 僕と母と淫靡な湯治と。 欲求不満の人妻は温泉旅館で息子に抱かれ激しく悶える近親相姦。 12人4時間

Like the previous entry, this is a digest version of Ruby's 'Mother-Son Intercourse' series. Since the source material is the Mother-Son series, it features all the familiar mature actresses you'd expect from incest-themed content. I recommend this for anyone who hasn't seen the series yet and wants to give it a try.
