He pulled back and stared at Sherlock. "Nom I won't live forever. My immortality was only guaranteed until Arthur woke once more and I was able to guide him." He said softly.

"I want to.grow old with you. I want to spend the rest of our loves together. But if for some reason I do live beyond you, I will never forget you, or love another. I haven't love any since Arthur all those years ago. But you... Sherlock Holmes. You... I love you. I love you before I knew who lived inside your mind."

John kissed him again, closing his eyes. The kiss was desperate and needy.
