You are about to see one of the most sexy photo-series we posted so far this year. This great work belongs to photographer JR Williams , work of whom we had the pleasure to show you before in Men and Underwear. The US based photographer collaborated with incredibly sexy former marine and now model, dancer and entertainer Esko Blazin . Enjoy the shots with Esko below wearing underwear and swimwear by Cockon, Freedom Reigns, Calvin Klein and N2N Bodywear.
