Oh, I'm so glad you enjoyed it! Definitely the weirdest--and porniest--sex I've ever written--don't know why these guys bring it out in me....But yeah, I was thinking of that moment in the first episode:

Sherlock: seen a bit of trouble then, violent deaths?
John: Yeah.
Sherlock: Want to see some more?
John: Oh god, yes!

He's game alright *g*

thanks for reading!
