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.
As for the Asian lady is very juicy and appetizing. But...again, the same Asian porn fad - blurry sharpness in the most interesting places. And it certainly spoils all the fun of watching the video!
