Arthur breathed in sharply at the sharp nip and tilted his head in response. It had surprised him originally, how teasing Tony could be when they were together but now he missed it when they weren't together. A grin curled on his lips as Tony guided him back to the bed. "Then we better get started," he murmured and leaned in to nip at his jaw.

In all honesty, Tony didn't have to remind him to get back as soon as he could - it would be the one thing on his mind the entire time.
