The act of making woman pregnant. Fertilization.
Basically in hentai, unprotected sex is as common as protected sex in real life. Usually though, nobody mention about possibility of pregnancy.
This tag however shows situations when rist of pregnancy is mentioned and nakadashi (Internal Cumshot).. performed, ended with wanted/unwanted pregnancy.
Something like.. please don’t cum inside me, it’s not safe today!
