Jack's grooming habits didn't concern Ennis, aside from noticing the longer hair, though if he'd taken time to consider it, he'd be grateful Jack had shaved, before he arrived. He wasn't a fan of facial hair, on himself, or Jack.
As it was, he was far more interested in Jack's body, and getting him in a better position to relieve Ennis' physical frustrations. He jerked his hands down to the front of his jeans, impatient to get the denim off his hips and discarded on the floor.
Jack was naked by this point, though Ennis wasn't in the frame of mind to take even a moment to admire him.
