My Uncle Saw Me On A Train Ride

I work at a trucking company. Last month, my uncle surprised me at work with lunch, i wasnt at my desk, somebody sent him back to where i was, he walked into the loading bay where around the back in a corner room I was getting railed by 7 guys taking turns with me on their lunch break. My uncle knew I was slutty but didn't know I did it at work ... I just do it to let the guys let steam off if they need a hole or 3 to offload into ... now I'm having to do it at home to he either watches or joins and I can't keep it to myself anymore ... im not against it, my GPA was my first and taught me everything but my uncle is being selfish and now wants me all to himself I live for free use though so I'm not sure what to do
