Justin sighed, a quick roll to his eyes and he was after her. He had to admit she was pretty fast and sure, his little fear of heights, had him tackling the stairs slowly, but she still was way ahead of him before that. It was easy to catch up - a little - once he was on the bottom floor, though. And he almost had her too - only an arms length away. Justin was too competitive to ease back and let her win this, even if he did need to take a breath.
He finally managed to wrap one arm around her waist as she slowed down to open her bedroom door. "Gotcha." He brought her back down; having lifted her a few inches off the ground, before letting his arm fall from around her waist, as he unlocked the door and walked out ahead of her into the room. "So what's my prize? What do I win?" He turned around with a grin.
