"It's good." Dean said around a mouth-full, before he swallowed. His eyes followed where she pointed and went back towards her just in time to see her take her shot. Dean smirked as he reached for his. "The whole point of the shot is for me to lick the salt of your skin." Subtle and Dean? He could do it. But why bother. Plus, he was just playing around. Not that he would have protested if she had remembered the salt.
He watched her, amusement clearly on his face, "Nice face there, Summers." With that he took his own shot, which would have gone well ... sans face scrunch, except it went down the wrong way. Of course it did. Dean tried to swallow his coughing but he didn't quite make it, eyes watering slightly, he cleared his throat deeply to remove that strong tickle.
Once he caught his breath he said, "If you laugh, you're not getting any ice cream." Despite his words, you could hear the slight laughter in Dean's voice. He'd deserve it after his comment.
