I very much agree with you guys that LP's most fatal problem is that he is afraid to let players see real sex, and he thinks his game may fall into mediocrity and boredom after sex, which is the problem with most AVNs. So he's trying to find ways to delay the game.
Even though each incident is different, the core NSWF content has been going on for more than 2 years in the exposed chest. He should have let the boys touch her body and caress each other long ago. So far she hasn't touched a dick other than her husband's at all, but what the latest update shows is that she has moral issues that create a huge cut from her previous image, yet she has not had formal interactive sexual encounters with the characters in the story.
