It's something to do with the Japanese obsession with literalness and being frank. Always talking, explaining every damned thing that's happening, what they're doing, what they're feeling, and what's about to happen. Just let them fuck and moan, the girl doesn't need to say "IT'S GOING INSIDE ME! IT'S SO WARM! UUUWWAAA" in literally every fucking hentai.
