The gang bangs continue part 1 (R)

Title: The gang bangs continue
Summary: "Don't be like that  doc. We all know the colonel doesn't mind sharing."
Rating: R
Pairing: Mckay/Sheppard established
Warnings: Attempted rape. Violence. BDSM relationship implied. AU.
Word count: A measly 781. But there's more coming.
AN: I said this could only end with Rodney dumping John's ass... and moving in with the marines... I lied. This won't make any sense without reading the prequel in which Sheppard gives Rodney to the marines as a butt toy (I admit, I just like typing that).
Believe it or not, but this has actually gotten just a little bit darker.
Disclaimer: If I ever get rich, I solemnly swear to buy the network. Until then, I own nothing.
