EMAV-023 - Mother-Son Incest: Yumiko Wakui

I'm sick of seeing the same reused room over and over. Even just making it look a bit more luxurious would change the atmosphere completely. Yumiko has a nice sex appeal for her age and good hip movement, which isn't bad, but the script is just unbearable. The first guy was so strange as a husband that I thought he was a lousy lover, but to find out he was the eldest son!! It ruined everything. Can't they cast roles that actually make sense?
