There was pleasure in tugging Miller along, catching the older man by surprise as he slowly but surely escalated things. There's a slight tug to the corner of mouth in faint amusement when the older man's lips part, and he fully took advantage of that to add an extra little bite to that lower lip then nudged his tongue into the other man's mouth carefully.

Then it seemed they were free to move as he was forced back a step then another until his back hit the wall behind him. His fingers dug lightly into the back of Miller's neck because he had already decided that this ended either by chasing the older man away with his presumptuousness or he had enough. There was a faint shiver across his shoulders at the bite, having moved his tongue out of the way in time. He gave a sharp jab of his tongue at Miller's upper lip before he tipped his head backwards and relented his grip.

Their task was complete. It hadn't been a terrible experience, and aside from Miller, they was only one other person he would prefer to do this with.
