The female cuckold, also known as cuckquean, is a female who derives sexual pleasure from looking at her partner (usually, but not exclusively, male) have sex with another person. As the cuckolding fetish is considered masochistic, it is considered a BDSM fetish.
More About Female Cuckold
A female cuckold is a submissive woman who derives masochistic pleasure by looking at her partner have sex with another person. The pleasure comes from the humiliation and the mental anguish caused by the knowledge that your committed partner is enjoying another person more than you. Some theorize that cucks eroticize psychological humiliation.
Cuckolding is different from swinging or threesomes in that the cuckolded person does not participate. It requires a certain level of commitment between the two original partners, as without an emotional connection, humiliation does not occur at the same level. Many cuckqueans are married.
One apparent difference between male cuckolds and cuckqueans is that while cuckolds focus on the pleasure of their wives, cuckqueans tend to focus on the pleasure of the woman her partner is having sex with.
