The way Diana moved in the moment was hypnotic. The world faded away from Thor's mind, all except for her hands in his and that look on her face. She gave him the Pout of Diana Disapproval (tm) and then the changes began. This time, she had to know what she was doing. Her voice was rough and... enticing. It was like a siren song calling a ship to the bottom of the sea. If this were a different time, a different circumstance, she wouldn't have been pulling back like that.
The lesser part of him almost didn't let her, anyway. But she did, all the same, and he smiled at her. "I'll hold you to that." He said, trying to sound nonchalant and unaffected. That was very much not the case though, and Diana would hear the pounding of his heart, loud as a drum, if she had the hearing for it.
