Underwater Apple Bobbing 

The same as traditional Apple Bobbing except that when a male or female inhales both of the balls of their male partner into their mouth, they perform the apple bobbing act underwater. Typically performed in a bathtub or pool.

Carl loves swimming at the local YMCA public pool. He enjoys wading around in the shallow end with his ball sack floating out from his swim trunks as the elderly lap swimmers love to do a little Underwater Apple Bobbing between their laps.
