Now here's a sure fire way to determine who the mom figure is in an NLT game: Other than oral copulation the first penetrative sexual act between the mom figure and the MC is always anal, i.e., the MC sodomises the mom figure before he enjoys her vaginally. Kind of disgusting but true. Thus neither Carol nor Nellie can be the mom figure in TGO, having already had penile-vaginal sex with the MC, leaving the Heather character who apparently has been waiting for years to fuck her "little boy". (And looks like she's getting featured in a scene doing so in the next update.) So if Heather's "little boy" buggers her before he fucks her vaginally Heather is the de facto mom figure of TGO, otherwise she isn't and there really is no hidden mom in the aforementioned game. And that will be that. Finally settled and settled forever one way or the other. What relief.
