Jack is back in Jack's Giant Juggs #4, adding some truly superstar talent to the roster. This installment finds Jack squaring off with some of the bustiest performers in the business, including AVN nominee Mackenzee Pierce, who seizes the opportunity to show off her new D cups. Mr. Napier's encounters with chesty thirty-somethings Sienna West and Kasey Grant will please MILF fans, while his work with Nika Noir and Brooke Banner should delight any big-tit aficionado.
