Young omega!Mycroft doesn't really want children (his career comes first), but when he tells this to his boyfriend Jim he is knocked unconscious and locked in the bedroom. For months he is held captive and fed only heat-inducers so that he would be unable to resist Jim's attempts to impregnate him before he is finally found and rescued while Jim is forced to run away and disappear to escape arrest. But the thing is - can Mycroft (and the child he could be carrying) ever truly be safe until his crazy ex-boyfriend is found and brought to justice...? NOTES: - Moriarty was never violent and he was not a criminal before he assaulted Mycroft - Mycroft definitely IS pregnant, but he still has options - to terminate pregnancy, to give up the child for adoption or to raise it himself (author's choice) - Sherlock has no idea what happened to his brother (he was either in rehab or still in college)
