When a female is on her back and giving a blowjob/being fucked in the mouth and the males asshole is nearly touching the females neck and double release of sperm and flatulence occurs simultanously.
While fucking that girls mouth and farting on her throat giving her a fartneck. Most easily achieved using a bed with a headboard to get the right angles.
