On my stomach with a leg up is always one of the best positions to get me farting. You call tell in this video because they are all pretty huge farts lol! I Get hubby to sniff up the first few in these sweaty, stinky strawberry boxers, and then he swallows the rest down his throat. These farts sounded like they were a lot to handle, but I wouldn't know, cause my seat sniffed and ate up every last one.
