I've seen the CG over on Hitomi. Pregnancy looks like a gameover scenario rathen than a mechanic; although weirdly enough, all Kristin's standing assets (including the preg ones) are in the files but with no scenes associated with them lol. So up to you
Lerd0 if you wanna add that tag or not. But I can verify with
Daedroth that it does get a bit dark. His warning is rightly made.
