NITR-037 is incest which I usually hate, but the main male actor was quite known and the acting was bad so its mattered not to me.
ZIZG is mainly monster sex (from anime/game I guess)
I still did crave those "definitely she got pregnant" moments
my criterion for impregnation-oriented AV:
1. fertile girl (peak of her cycle, positive ovulation test, etc)
2. lots of creampie (I did miss dildocam after creampie, there are several of them)
3. confirmed pregnancy (belly bump, positive pregnancy test, gave birth 9 month later, etc.)
