Marcus's eyes had closed tightly when he kissed her, pressing her back against the wall until he was sure she knew what he was trying to say to her through the action. When she pulled back he took the chance to fill his lungs, cracking his eyes open to look down at her.  Her expression said as much as her words and it brought back alk he had fekt that night on the beach.  But the strongest returning sensation was an unquenchable desire. 
Still a bit breathless he nodded, "I need you to,". He said against her lips, before tugging her along with him out of the middle of the hallway and from prying eyes with his arms still around her.
