Hmm.. we could do this..<br/><br/>Once an Icubus is born it very quickly develops and matures to a point where it could "Feed" itself, as a consequence for the rapid growth it is forced to go on a feeding frenzy large enough to be worth about 16 years of meals, then the extended timeline kicks in.<br/><br/>Or we could  say that it's like humans do it, the mother feeds and breast-milk! Personally I think that would be quite erotic if like a student or faculty member has a small child that they must breastfeed during breakfast or classes.
