LOS ANGELES—He’s big, he’s black, and he’s back ... this time to celebrate the rack.

Performer-director Jack Napier, a 2010 AVN Award winner for Best Interracial Series for It's Big, It's Black, It's Jack, is also an old hand at a big-breast series. And he folks at Vouyer Media say that his latest foray into the genre, Jack's Giant Juggs 4, hits the balls out of the park by adding some diverse star power to the talent roster.

Now in stores nationwide, this all-new installment finds Napier squaring off with some of the bustiest performers in the business, including AVN Award nominee Mackenzee Pierce, who displays her new D cups in some hardballing XXX action.

Also in Jack's treasure chest: encounters with Sienna West, Kasey Grant, Brooke Banner and Nika Noir, all designed to delight big-tit aficionados.

The plentiful DVD extras include a bonus encounter with tatted-up "Double D Diva" and alt-porn sensation Scarlett Pain, as well as a generous gallery of XXX stills. Tie it together with stylish O-card packaging featuring cover girl Nika Noir in all her glory, add razor-sharp 16:9 HD videography and you've got a definitive exercise in busty interracial action.
