" Thorn"
Thorn, aside from being the editor of Instigator magazine, is one mean taskmaster of a dog trainer. In Rough Trade LA, Thorn puts dog boys Brian Mark and Wyatt Trash through their paces, making them sniff one another's asses, suck his cock and drink his piss from the dog bowl. At one point, Thorn pisses into a beer bottle, pours the contents into Wyatt Trash's hot muscle hole, then forces Brian Mark to drink the recycled brew from Trash's hole. Thorn is the personification of pig fun.
