While it is still in violation of the laws of thermodynamics, the setting still specifies that it has a limit in that it requires one incubus and one monster, no more and no less. Namely in the incubus section of Fallen Maidens it says:

"as long as there's one incubus and one monster, its possible for them to live by just having sex."

In contrast nowhere to my knowledge does it say that an incubus can be the sole source of food for a harem, only that he will have to provide a lot of energy to satisfy their lusts.
