Mongolian paddleboat mutiny
A sexual act in which a female partner gets 6 of her friends to drink yak's milk for several hours, the male partner is then beaten with leather straps or belts while the women urinate on him, simulation the act of mutiny on a Paddleboat adrift in the Mongolian Sea.
Being a high-powered alpha male rocket surgeon, the only way I can get off while I'm on leave from Seal Team 6 is when Debbie and her knitting circle surprise me with a Mongolian Paddleboat Mutiny.
