HMA-006 - Mother's AV debut, being ravished in front of her son

She's a mature actress who looks like Mari Nishio and is full of sex appeal, but the male actor and staff are so noisy that it's hard to focus on her. It feels like one of those old Showa-era underground tapes. The scene around the 57-minute mark where she leaks fluid as the vibrator is pulled out during doggy style was memorable. I'd like to see this actress in other works.
