The rough shoves and hard kisses were typical foreplay for Ennis and Jack. Ennis needed to be physical, to get the bulk of his resistance out before he sought to possess Jack's body. He swatted at Jack's hands, but without much force. He wanted the belt off. His resistance was formality.
His knees bent, bringing Ennis forward. Hands on Jack's shoulders for balance, he heaved himself back up. The ghost of a word flittered on the air, though said in such a way that it might be impossible to discern if he'd ever said anything at all.
