I think single sexual intercourse with an incubus is enough to transform a human girl into a succubus, since succubus can transform human girl in single act.

However, I think incubi rarely has sex with human girl. From their point of view, human girl lacks stamina and few other qualities to satisfy their demonic lust. And since most incubi were transformed by a mamono, they will have better partner from start. The only exception, IMO, is when the girl is a girlfriend or love interest to a newly transformed incubus.
