You've invited your thick ass step-grandma to a pool party hoping to see her in a swimsuit. When she arrives she's reluctant to take off her cover up, she admits her booty is extra thick and she isn't sure about flaunting it in front of a bunch of young guys like you. You encourage her to show you so she drops her robe and you immediately get stiff. She notices and teases you a little, but soon it goes to her head and she decides to show off her thick booty while telling you how to jerk off for her. She knows you need to drain your balls for the party so she goes all out jiggling her fat dump truck ass until you cum.
