"Oh, you are my good boy. I promise I want to make this good for you." It was such a strange paradox, that John could be in his massive Demon form, and still fall under and trust Sherlock enough to take care of him. It was a huge responsibility, and one that Sherlock took quite seriously.

Sherlock worked him open a bit more, using his wrist, and then the very first part of his arm inside of John, stretching him wider and wider.

"Look at my wonderful, wonderful boy. You are all stretched out around me, big and gaping and open, aren't you? I think it's time you got your reward. Do you want Daddy's cock in you now? I know I won't open you up like my fist will, but I can give you your sticky reward. Is that what my good, sweet, wonderful boy wants now?"
