sga slash link: not really a rec (a moot point, since it's incomplete)

sugar and chi expressed desires to read this partially-completed sheppard/mckay fic i was talking about over some excellent fried rice this evening.

note 1:  it's only 4/5 completed.
note 2:  in this story, aliens use a weird drug and a combination of psychological and physical conditioning to make rodney feel a physical imperative to please sheppard.  and also a craving for his touch.  and a headache if he thinks sheppard is displeased.  you get the idea. 

it's called "truth" and is by burntsmore.  parts 1-2; parts 3-4.

“Shut up.” John kissed him this time, fingers twisted in Rodney’s hair as he held his head and sucked on his lower lip because Rodney’s jaws were clenched shut. “Open,” he growled.
