I would agree and disagree. Agree that quick corruption and non-stop fucking where the girlfriend/wife turns into an insta-slut is boring and a turn-off.100% agree
That said, these are supposed to be a porn games/stories, right? If you want a harlequin romance or lifetime channel feel good stories you're in the wrong place.
A skilled writer can develop characters and make porn stories that are erotic and have a plot that engages their audience beyond just sex. Unfortunately, not all writers are that skilled, or maybe they are but ultimately they succumb to financial supporters who have no patience and want quick action.
