I call bullshit on this or you're just confused. After scouring for guides online within those 100% completed and unlocked; nothing is mentioned of what you describe. The total number of fellatio scenes is 3 and they are dependent upon lust. If there were 2 versions of the high lust fellatio scene as you claim, then the game would add an entry of it in the "Memories" replay section.
