In a world where some people are naturally inclined toward submission (call them what you want), slaves are accepted, fairly rare and highly prized. They can be discovered at any age. Somehow - up to you - it is discovered that Sherlock is one of these people. Whether he knew beforehand or not is your choice. How John gets ownership of him is also up to you.

What I'd like to see: A very submissive yet proud Sherlock struggling with his desires. If it ends up long enough, I'd love to see him beginning to submit to John of his own free will - learning to take pride in who and what he is now.

Would love a scene in which John uses pleasure and pain to make Sherlock feel a way he has never felt before, yet Sherlock still fighting it still.

Kinks are up to you but I love me a bit of breathplay!
