Please Don't Eat My Mother (1972)

Please Don't Eat My Mother (1972) is a softcore take on the Roger Corman comedy-horror Little Shop of Horrors (1960), with a talking plant that demands to be fed people. The schlub who owns the plant lures hookers and swinging couples to his home for the plant to eat, including hardcore hottie Rene Bond and her real-life husband and onscreen bang partner, Ric Lutze. The nudity is full frontal, and carrot top (and bottom) Alice Fredlund makes a most delicious plant food. As the title says, even mom is fed into the plant, but thankfully not naked.
