Once again, Draco’s mouth popped open, too much was happening right now for him to process. His hands slipped down off her arms and to his sides, as much as he wanted to keep touching her - touch more of her. She didn’t remove hers though, she was looking up at him, hands fisted into the robes at his hips and she bit her lip. She went to reach down, back to the shelf she was looking at when he’d come in, and let her other hand drag across his front, right over his crotch. Draco froze, he would swear that all the blood, oxygen and magic in his body took an express train right to his lower half. He didn’t move as Granger let her hand settle on his leg. Grabbing his thigh, she stretched her arm far back onto the shelf digging her fingers in a bit. His cock throbbed almost painfully. She came back up, letting her hand ghost the front of him again, feeling how hard he’d gotten. "There wasn’t anymore waterwort on the normal shelf, I needed to find the reserves. Here. Why don’t you take enough for the both of us, Draco." She smiled again as she held the jar up to him, looking into his eyes.
