Kenzie, who is currently unhappy in her OWN marriage, seizes the opportunity to suggest a threesome with her -- that way the wives can both receive anal at the same time! The wives are shocked at first but, after some convincing, decide to give it a try to save their marriage.
They then have an energetic threesome... only to be interrupted midway through the sex when Kenzie's wife calls. But it doesn't stop them from continuing to have lots of anal-focused fun!
