Just played the intro and it's pretty good until the end.
Ash's family are a mother and father we don't see and who apparently don't approve that Ash is gay.
The groundwork for the gay and sissification tags are there, but there is no sexual content yet. (Ash likes dressing in girly clothes but hasn't gone full femme yet, and he lusts after his hot new male neighbour.)
There isn't even a hint of incest in this version.
Currently I personally believe it needs the trap tag (because the MC starts as a male that dresses femme).
As for the ending, getting raped is a deal breaker for me, so if that goes through I won't be continuing with the game.
Which is a shame because I love a good sissy game.
