CXR-004 - Mother and son hot spring trip, couldn't hold back anymore

The story is wild: a mother (Momoko Minami) is raped by her son's teacher and forced to perform oral sex on her son right there. She goes on a trip to Futamigaura with her sister (Aiko Kinoshita) and her niece, but during hitchhiking, the sister gets kidnapped and raped. The son saves her just before she's held captive—what a plot. That night, Aiko gets drunk and sleeps with her young son. Her bed scene performance, utilizing her signature butt, is masterful, and Aiko's large nipples are quite something.
