Dev doesn't reveal anything about the next update except for some pretty neutral footage from future scenes that make it hard to guess what's going on. So no one knows shit. All you can hear in this thread is someone's guesses or wet dreams.
I would guess that the new chapter will have a lot of nudity and seductive poses, but it is unlikely to go further than petting or blowjob. Another popular idea is that the trip with Amber to the cabin as part of her "unconventional" therapy may end in a juicy lewd scene, but even if this happens, I think it will be more of a light erotic scene than porn in all positions from different angles.
But these are just speculations.
