It takes a steady tongue and a steady mind to give a rimjob, and performing feats of acrobatic strength is not generally recommended during the act. It's got to be doubly hard to snap a selfie while performing such a feat, so we've got to hand it to these guys, they've got what it takes.
If Cirque du Soleil is hiring for their "adult" show Zumanity anytime in the future, they may want to look these guys up. Hell, they may already be cast members.
