Sherlock had never.. ever done this.. but he wanted to give John the ultimate gift, something that he had not even given the Old John. the before John. A gift that he hoped John would understand the importance of.

Without a word, he rolled John over until John was on the bottom on Sherlock on top. He hovered over John's cock, sitting lightly on it, not enough pressure to hurt, but enough to hopefully give John the idea of what he was thinking.
