Terrence should have known that a lack of resistance in getting her over his shoulder didn't indicate that this was going to be easy. He made it a few steps toward the door, feeling rather victorious, and stopped, flinching a little instinctively when she smacked his arse. Though he really didn't mind, it just took him by surprise.
He fought to keep her in his grip, but failed, and laughed when she got the better of him; he would have been hard-pressed to be irritated about it. Not only did she fit nicely in his arms, as he'd discovered the day before, but having her arms and legs wrapped around him - not to mention the way her body was pressed flush against his back - wasn't bad either, not at all.
And honestly, he had no idea what he had meant by doing this properly. At this point, he was awake, and they were both out of bed, so it probably involved some form of exercise, even if it was just running around with her on his back.
"You forfeited the right to object to kidnapping when you woke me an hour early," he said, tucking an arm under one of her legs to support her. With the other, he got the door open and closed it behind them, then held onto her legs with both hands as he took off down the hall.
Oh yes, he was awake now - and she had asked for this, with her teasing when he was waking up. He didn't care if they played Quidditch or not at this point, but he was heading for the pitch just because it was somewhere to go. Maybe he'd climb on a broom with her on his back and chase after the Snitch, that would be an interesting exercise.
