His hands were pushing upwards, shoving Andrew's shirt up, and when he did pull away, it was only to yank the hoodie up and over Andy's head. He flung it backwards, over his shoulder.
He took a moment while he was up there to grin at him, and then he was back to his work, nibbling along Andrew's collarbone, tongue sliding over the groove the bone made.
