And then the bushes started to move... And every hunter in the big wild savannah thought there is a big grizzly bear in the bushes... if they would know, that only Sam and Dean tried to play something more adult game.
It's in the trunk because one of 'em left it in his other pair of pants. Apparently, however, Dean is SO horny and the spot he's eyeing for the spontaneous buttfucking is SO perfect that he just can't wait for lubrication, damnit!
