You should exchange wives to refresh your emotions, to feel macho. And wives, in fact, it's nice to be able to feel other men's dicks getting up on her. The video is great - everything is real, with real wives. The younger one was even spanked in the ass. And popularity acts as an aphrodisiac on any woman. The instinct to spread her legs and give - is inherent in the nature of chicks.
"Ran" is a bit of a mouthful. She was showing signs of attention to her stepson from the very first seconds of the video. Generally speaking, stepmothers are the easiest to divorce, they don't mind jumping on a younger guy's dick themselves, while living with his father (a richer man).
Oh, fornication.
