"I'm pretty stubborn when it comes to something I want," he murmured, curling his fingers gently, scraping his blunt nails along the skin before stroking back and forth slowly. "I push and push and push until I get what I want. You might get tired of me wanting the practice."

He doubted that, though. Not if Krem's smile was any indication. Not if how warm and heavy he was against Thomas was any hint as to how much he was enjoying this too.
