Under the mistletoe, Casca Akashova and Avery Moon share a heated kiss, their bodies pressing together in anticipation. Unbeknownst to them, Avery's son is hidden in the closet, his cock hardening at the sight of his stepmom and stepsister entwined. When Avery notices him, she doesn't stop. Instead, she beckons him over, guiding his thick cock into Casca's eager mouth. The room fills with the sounds of their moans and the wet slapping of flesh as they explore each other's bodies, their Christmas surprise turning into a wild, taboo threesome that leaves them all panting and spent.
