Reason for restraint

"In that case... What?" Claudia asked, snuggling a bit closer towards Tom. Her face looked strange as if there was something important on her mind. "Or rather, what wasn't enough?" she added another question, gently placing her hands on Tom's shoulders. 

It was a simple act of holding her hands beside Tom's neck. She didn't hold her fingers down nor resisted any notion of moving away. She just stood there, halfway between hugging Tom and clasping her hands on his throat. 

"This isn't something I'm sure about," Tom shook his head. "It's something I only guessed, so I didn't want to bother you with it before proving I was right," he added. Tom then placed his own hands on top of Claudia's. "But since you insist, allow me to explain." 

Tom clasped his fingers over Claudia's hands, removing them from his shoulders. He then let go of the girl's flesh, stepping away.
