Cas turned to her as her hand slipped around his back, half-smile fixed in place. "It's OK, Jo. And I really don't wanna punch you, unless you're into that I mean," and his smile took on a playful edge. "You can finish the cake... I'm curious now. Never got to try it." He didn't move away from her, though. He couldn't deny her hand felt... He caught her eyes in his blue gaze.
"I guess I could..." and he leaned in, his tongue darting out to collect a crumb of cake that rested at the corner of her lips. "Hmmm. Not bad," he grinned, his tongue slipping over his own lips thoughtfully.
