SPRD-883 - Mother-son taboo with Mitsuko Kamijima

This work, where a mother and aunt get involved with their respective sons, eventually became a series, but this might be the peak in terms of eroticism. Mitsuko-san's massive breasts and lewd pussy are must-sees. The dialogue is a bit incoherent, which is distracting. Also, the actor playing the son looks way too old to be a college student, and it's a shame that he keeps losing his erection during the act.
