Kourtney Kardashian in behind-the-scenes shots for GQ Mexico

Kourtney Kardashian gets hearts racing in sheer lace bodysuit in behind-the-scenes shots from her GQ Mexico spread.

And Kourtney Kardashian shared some smoldering behind-the-scenes shots from the steamy shoot via Instagram Thursday.

The eldest Kardashian sister, 39, looked absolutely sinful in a lacy black bodysuit which put her sex appeal front and center.

Leaning back on beautiful marble table, Kourt showed off her enviably toned legs and all-around bronze. 

She looked down, casting her dark tresses over one shoulder.
