Most effective when your girl is giving you a blowjob and licking your balls, you ask her to open her mouth wide and... you push it out forcefully. Just make sure you take cover immediately upon letting it rip. You can't beat the pure pleasure of farting while getting a blowjob!

Last night, hit a good lick. I brought home three figures easy for about two hours worth of my time. Not too bad I don't think.
