I would rather say it is good catch than weird. Asian culture has some taboo aura regarding genital area. Which, has influence on erotic literature when it comes describing intercourse.Animation 4: Pricia - Scene starts with "stretching" which is basically twerking. You finger her while she's stretched and the view is great. She's dripping and everything. Awesome insertion scene. She says constantly how tight and small her pussy is and they did a really good job at making it feel like MC was stretching it out. Scene is standing doggy. Nice cumshot on her ass. My complaint about this scene is the way Pricia speaks during it, you'll see she has a very distinct syntax, referring to her pussy as her flower, calling you gentle, etc. It's weird. I get why it was done though, you can't have every character being a dirty mouthed slut, but it just struck me as strange during the scene.
For some audience sex talk with indirect wording could be as hot as dirty talk for others.
