I search for corruption, find a precure doujin, and start reading it. It has pretty nice art and entirely yuri action, not even futa, which is extremely rare. The corruption progresses decently enough, and it doesn't even fall back on overused visual tropes like crotch tattoos.
Annnnnnnd then it ends with mindbreak instead of any actual evidence of corruption beyond a mild costume change, plus random het sex. Nothing wrong with het mindbreak, but why shoehorn it into what was shaping up to be something actually unusual in an appealing way? Without further context, it's not like it's even good as het mindbreak. Totally dropped the ball.
This isn't even a diss, it just comes out of nowhere and has no context. I'd at least understand if it there were some anti-lesbian aspect to it, some people fetishize that. As it stands, the last two pages are just confusing.
