This is what he needed. The loss of their dad had been a devastating blow, but if he ever lost Sam? He didn't know what he'd do. He'd spent his life watching out for the kid, felt responsible for him... losing Sam would be the same as losing some part of himself.

Sam was what kept him human more than anything.

He tilted his head at those kisses and gave a soft, pleased sigh. "Mhm... promise you anything you want, Sammy."

Giving Sam everything was a natural urge too.
