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.
The lady is of course old and fat, her tits are saggy too. But for all that, I would have loved to spend time with her, she was still very attractive. Personally, I wouldn't go down on her tits. It's much nicer to fuck her in the mouth a little at the end and cum in the same. It's especially nice when a woman works you with her lips for a few more minutes after you cum. The pleasure just makes your eyes pop out!
