Stepdad and stepmom's steamy encounter, mom with a voluptuous derriere

I\'m not your average guy, but my girlfriend\'s mom has the biggest ass I\'ve ever seen. When my wife isn\'t around, I can\'t resist giving her a little loving. This curvy, thick, white MILF is off-limits, but sometimes I can\'t help myself. It\'s all about the ass, baby.
