Colt is a Dom cowboy, eager to tame his stud, Siren on the Farm. Bound up like a piece of meat, Siren gets manhandled by Colt in the sun; from being groped to getting throat-fucked and flogged, Siren really gets broken in. Then Colt herds him to the dungeon so he can stuff Siren with a fucking machine, leading to a man/machine spit-roast. Finally Siren is hogtied and bit-gagged so Colt can mount his ass, really stretching out his hole, which culminates in Colt marking his new stallion and making him part of his stable.
