"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).
Posh lady and anal well developed! My dick goes in with a bang! But I personally would fuck her in the ass too, it's a shame not to try such a gorgeous lady from all sides! And one more thing - you shouldn't fuck in the anus without a condom.
