Six kids and still killing it! Kim Zolciak is loving her beach vacation with hubby Kroy Biermann and her six kiddos. The family's excursions have been thoroughly documented on the reality star's Instagram page, including a series of bikini shots. 

"Lovin that salt on his chest!" the Don't Be Tardy star, 36, captioned a shot of herself wearing a green bikini and licking her football-playing husband's bare chest. 

He loves me just way I am ???? #ItNeverGetsOld #IMustHaveDoneSomethingRight ???? #AskBelieveandReceive

She also posted a photo of the athlete lifting her in the air, showing off her impressive booty and flashing a little side boob. 

"He loves me just way I am #ItNeverGetsOld #IMustHaveDoneSomethingRight #AskBelieveandReceive," she captioned the sweet pic. 

Zolciak also shared a series of family shots with her many children, including her look-alike eldest daughter Brielle, 18. The teen has gotten a lot of flack for dressing too maturely for her age, so Zolciak tried to combat that in the caption of Brielle's bikini image with her boyfriend.

"Hey cuties @briellebiermann @sladeosborne #SheIs18AnOldEnoughToHaveABoyfriendSoShutUp #SheIsOldEnoughToWearABikiniSoShutUp #SheIsConsideredALegalAdultSoShutUp #SheIsStillMyBabySoShutUp," she wrote with the pictures.
