Caught having fun in the mud - outdoor public

On a muddy field, I piss on my subs short jeans and into his wellington boots. Then I order him to run around. After some time he falls into the mud and I want him to crawl towards me. I push him down in the mud, then I am about to rip his jeans off to fuck him... But some bikers burst into our recording. So we go home and I fuck him bare in the shower, before washing off all the mud.
