Kim Zolciak and Kroy Biermann can't keep their hands off one another.

The 37-year-old former Real Housewives of Atlanta star and her NFL pro hubby were feeling pretty affectionate while enjoying some sunshine recently, and Kim just had to share with her Instagram followers.

The reality star posted a picture of Kroy grabbing her skimpy green bikini top on Thursday, with Kroy sporting a huge smile on his face.

"The beach has been amazing," Zolciak wrote.

She followed the racy pic with this picture of the two kissing by the ocean, showing off her tiny waist.

... And Kroy's white Speedo is pretty revealing too!

"Paradise," Kim captioned the shot, also shouting out her 18-year-old daughter, Brielle, for taking the PDA pic.

Kim and the 30-year-old Atlanta Falcons defensive-end have been married since November 2011, and obviously, their spark is still alive. They have four children together: Kroy Jagger, Kash, and twins Kane and Kaia.
