Kristy May, the skinny blonde, shakes her booty, unknowingly teasing Dr. Grey. She grinds against him, her panties the only barrier between them. 'Fuck my panties,' she whispers, pushing her ass back. He obliges, humping her from behind in a prone bone position. Her panties grow damp with both their juices. As he nears climax, she encourages, 'Cum inside me.' He does, filling her panties with his creampie, the sight of her panty-fucking fantasy coming true.
