Jack didn't understand a word that Scotty had said, but that didn't matter. It was hot, and Scotty was playing into that, knowing Jack liked it, and it was even more hot for Jack because of that fact. Jack sped up the pace, knowing that he wasn't going to try and hold out forever, and hoping that Scotty would follow suit. Not that they were being quick about it, but that he just really wanted to enjoy himself in the other man's company, and there was no point in drawing it out either.
