In the cold, sterile confines of the prison shower, a towering, hairy bear of a man, his muscles glistening with sweat and water, pins his scrawny cellmate against the wall. The inmate's eyes widen as the bear's massive, uncut cock presses against his ass, feeling the heat and anticipation. The bear, driven by primal instinct, grabs the inmate's hips and slams his thick cock deep into the tight, welcoming hole, fucking him raw and rough, just like in the animal world.
