Seeing the one with Ashley and her "DnD" friend....Something tells me that the moment Ashley shoves her friends head down that cock, an announcer with a stern voice will say "FATALITY" ...
But for real, those are all great poses...how about a "one time thing"? Like, in one scene MC really wants to bang two girls and is like "man too bad I only have one massive cock...gotta do one after another" and Lillith (who is already around) is like
"Who says you can't?" flicks her finger and MC grows a second, identically sized penis...and well ya know.
But then again, which mortal woman would...not question that? So only way this works is with someone who knows about the Demon Deal.
