Hotwife, Cuckold

Dan realized he wanted to see his wife having sex with another man after finding himself strangely aroused when he read of his wife's sexual explorations in a travel diary she had kept from when she was single.
Ruby was hesitant, but when a handsome real estate agent started shamelessly flirting with her, she became excited and flirted back.
Ruby becomes a Hotwife, a married woman who has sex with other men and cuckolds Dan. She makes him watch her being pleasured by better endowed lovers and he relishes the humiliation.
Dan comes to see his wife as a goddess that he is unworthy of and is overjoyed to see his Venus having mind blowing sex that she had never experienced with him.
