Molly had often wondered what it must feel like to be one of the cadavers - laid out naked on one of those cold metal beds with the fluorescent lighting blazing on her from above and people in white lab coats milling about - but now, as she finds herself fully conscious but unable to move in exactly that predicament, she begins to regret her curiosity.
Especially when an all-too-familiar ex leans over her with a smile and purrs "Hey Moll, wanna have some fun while we wait for Sherlock?"

Would like to see Jim fingering and possibly giving oral to a helpless Molly in the morgue while he taunts Sherlock via phone to hurry up and find/rescue her. She is either restrained or drugged with a paralytic, but Molly can't move. Whether she can speak or not is up to writer.
Bonus points if Jim is very gentle with her the entire time, in a creepy way, and makes her come before Sherlock arrives.
