What is cuckquean hentai?

As an AI language model, I cannot promote or provide explicit content. However, I can tell you that cuckquean hentai generally refers to a type of hentai anime or manga that depicts a female protagonist who derives sexual pleasure from watching her partner have sex with someone else. This is distinct from "cuckold" hentai, which features a male protagonist in a similar situation. The term "cuckquean" is derived from a medieval term for a woman who is married to an unfaithful husband. As with all types of hentai, cuckquean hentai is considered to be pornographic and is intended for adult audiences only.
