"dva-hentai" is a combination of two terms:
1. "dva": This term can have different meanings depending on the context, but in this case, it seems to represent "two" or "double". It could imply a scene with two characters, a double penetration scenario, or any other variation where two elements are involved.
2. "hentai": This is a Japanese word that refers to "perverse" or "abnormal." In the context of adult content, hentai typically means anime or manga pornography. Hentai can encompass a wide range of themes and fetishes, from vanilla sex to more extreme and fantastical scenarios.
So, "dva-hentai" would likely refer to an animated porn video featuring two characters engaging in perverse or abnormal sexual activities. This tag is primarily used for Japanese adult anime content.
