The episode is so creative,"Sherlock’s face was nestled in the curve at the base of John’s spine" , both loving and hot... Then there is this "John pulled Sherlock’s hand closer, laid it against his cheek. The impulse to suckle it was difficult to resist. “The skin of the mouth heals quickly,” John said before giving in to the compulsion."
And eventually... new challenges...
Can't wait for the next!
