CUCKOLD:
A submissive husband with a wife who takes on alpha-male lovers whereby the wife's sexual pleasures become the husband's vicarious sexual pleasures and experiences.
The cuckold husband developed an erection as his imagination ran wild with sexual thoughts during the preparation of drinks for his wife and her new lover.
HOTWIFE:
Generally a Hot Wife is an attached woman who makes herself sexually available to other men, often with her partners knowledge and consent. However, there is a fast growing "segment" of Hot Wives who enjoy being sexually available to other men without their partners knowledge or consent. Many wear very revealing clothing, flirt outrageously with their partner present, and generally, revel in the intense attention they get from (and give) other men.
