Mac groaned as he felt his hair being tugged. Something that he knew logically that in their line of work for so long that being pulled about should not do things for him. Or more directly in the case of Jack. Jack could do things that no one else could. He ground himself against Jack's leg as he kept going. No chance he was going to stop until... he did stop. He forced himself to stop. Pulling back, panting and looking at Jack.

Looking over at Jack behind him as he pushed his jeans and boxers down so they were around his ankles. "Come on then sheriff, show me what you can do."
