You really love to be purposefully ignorant on that game...
First of all, Glamour has been incest from the get go. I know, it's DS and his hypocrisy
again.
The original MC Kate, lives with
her sister (game intro explicitly labels Kate and Julia as sisters) and eventually engages in sexual relations with her, and her boyfriend to some to some degree (optional sex with him if the player chooses).
Second, the later "Alex" MC who was just a gender swapped Kate, has been replaced with Max and a remake of Big Brother.
Content wise as Max, he's at the point of getting hand jobs from Lisa, some of the latter sex-ed with Lisa and Ann, and is able to go down on Kira on a nightly basis.
This is all with Kira playing a bigger (somewhat) role in the household, and the player is now able to actively see her working to push Ann into things with Max.
All this without even a sight of Eric... So far. (There's hints at him, and one conversation with Ann & Max that looks like it locks Eric out if you choose that option.)
Oh, and "Max & Co" can be named as family in the options menu... Wonder how long that'll stay under Patreon's radar.
When it comes to Alice though, it's currently nothing more than spanking at the pool with Max. The majority of content with her is with Kate, as another same-sex partner other than Kate's sister and a couple of other women around the town, one of whom is a teacher at the school where she first meets Kate.
Ultimately Kate has the most content, but on the whole both "sides" of Glamour are way behind where I'd say they should be for how long this has been in active development.
