Bound to You | Johnlock + Mystrade | Sherlock BBC AU

Mycroft and Sherlock were cursed to live forever. If they fall in love the curse will be broken. If their feelings are not returned they will die. Unable to cope with the idea of living forever alone they try to dissuade the other from forming attachments to John Watson and Greg Lestrade. Unfortunately they can't help themselves and when the curse starts to weaken them they have no choice but to admit their secret.
