A smokin' hot Brazilian MMA fighter says she was forced to stop a sexy beach photoshoot this month -- when she saw some creepo rear-naked chokin' his own chicken while watching her from the bushes.
Oh, and then she proceeded to BEAT HIS ASS!!
The woman is Joyce Viera -- a 27-year-old amateur fighter and swimsuit enthusiast from Brazil. Her IG page is FIRE.
Viera claims she was posing for pics with her photog crew when noticed a guy watching her nearby -- and when she approached him, Joyce claims his penis was out and it was obvious he was pleasuring himself.
