As long ago as the perk list was leaked, a lot of it has been confirmed. If my memory serves me right - only the bdsm content between Asuna and Inoda was not confirmed, though Fujino may or may not add one scene to close this fetish in the future.
According to the perk list, after the condomless sex there will be group sex and Liz's entry into Inoda's harem, which is happening now, and if Fujino hasn't changed his mind, in the next 2-3 updates Liz will fully become Inoda's whore and join Asuna in servicing Inoda.
Judging by the list of perks after the group sex, the climax of this work is Asuna voluntarily agreeing to get pregnant by Inoda. That's it, there's nowhere else to go, and the list of perks ends.
