Under the guise of family therapy, Frintteza and Frintezza share a bed on Christmas Eve. As the night grows colder, so does their resolve. Frintteza's hands wander, cupping Frintezza's big, warm ass in her Grinch panties. She responds by grinding against his growing erection. They strip, their bodies entwining, Frintezza's large, natural breasts pressing against Frintteza's chest. He enters her, filling her pussy with his hard cock, their moans drowned out by the crackling fire. They fuck missionary, Frintezza's long legs wrapped around her stepson, until he can't hold back, pulling out and creaming her pussy, their Christmas celebration complete.
