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. The plentiful DVD extras include a bonus encounter with "Double D Diva" Scarlett Pain and a generous gallery of XXX stills. Tie it all together with stylish O-card packaging and stunning 16:9 HD videography and you've got Jack's Giant Juggs #4 – Mr. Napier's definitive exercise in busty inter action.
