>should I play bs1 first?
Yeah. 2 is a direct sequel so you won't know what's going on if you don't play 1 first.
You should really get all the endings too. At the very least, save ending D The Black Trial route for last.

Most of the time H-games get a pass on steam because they're sfw with an offsite patch. The ones that usually get hit are /e/ games.
Although, Subahibi on steam was uncensored, except for the removal of a single bestiality scene, and is still being sold. Not really sure how they managed to get away with that one.
