How many facial muscles are in use for a 'peck on the lips'?

Explanation

The most important muscle when kissing is 'orbicularis oris', which makes it possible for the lips to wrinkle. A French kiss is coordinated by up to 34 facial muscles and 114 other muscles, whereas a quick 'peck on the lips' only involves 2 muscles. In 2011, a Thai couple kissed for a total of 46 hours, 24 minutes and 9 seconds, which makes it the longest kiss in history, according to the Guinness Book of World Records.
