ABD-036 - Mother and son incest - Son jealous of mother's affair

The actress is beautiful with an outstanding figure. She has that perfect mature woman's allure. Her breasts are so firm it makes me suspicious, but the way her nipples stand up when exposed from her bra is incredibly erotic. The plot involves a frustrated wife whose son overhears her on the phone with an affair partner; he blackmails her into performing fellatio. She tries to masturbate out of frustration and begs her son for sex, but it only goes as far as petting, which is disappointing. Even in the bath scene, there's no penetration, just somata, leaving me unsatisfied. She finally gets to a sex scene later, but it's only once, which isn't enough. She's pale, has a great body, and plenty of sex appeal—I really wish they had included more sex scenes.
