It was a hot summer day and James was taking a nap. Dave had just got back from playing basketball and had some major swamp ass, so he decided to share the wealth by giving James a swamp asstache!
When one indirectly gets cock and/or ball sweat in their mouth!
Russ was wasted and was chasing everyone around with his cock out, so Dave smacked his junk to get him to put it away! Dave then deciding to implement "The Arnett" turned around and smacked Joel in the mouth as Joel was laughing at the whole situation, basically getting Russ's swamp juices all around and in Joel's mouth!
