Wow. Writing in this was so bad. it was like a caricatyre of the human behaviour. Perhaps this was written by A.I. who just started to learn how to interact with others? I played first part ages ago and I don't remember it being quite this bad. Story setting itself is somewhat interesting (if you avoid NTR). And I don't mind seeing, that suddenly all females seemed to be walking around nude, but writing leading into those scenes could use plenty of improvement.
Sex is also very plain. You lick or finger her, or she sucks and then they fuck, all that within few screens. Not much conversation leading into sex.
