Very hot, and also an extremely interesting pairing that I think would really work.

Creates an entirely realistic Father & Son relationship between House and Sherlock.
Under the Sheets by gaby0189x Arthur/Eames
HOT! An excellent story of their relationship.
Teardrops by gaby0189x Dom/Mal, Arthur/Eames
The story of how the four came together, and the aftermath of the movie. Beautiful, touching, heartbreaking.

Phenomenal tale of love through the ages.
I Swear by dualbunny, greensilver, and sweetestdrain, Clark/Lex
OMG if you haven't seen this you need to. It is CRACK, crack to be watched in a space safe for loud noises.
Family Business by newkidfan, Dean/Castiel
An amazing AU in which Castiel is an assassin and Sam and Dean are the FBI agents hunting him down.
I Want You by Maichan2, Sam/Dean
I love the way Maichan manipulates the footage to make it look like the boys are having an actual conversation about their relationship, with Sam asking and Dean saying no, until he gives in. Maichan actually makes a super-hot 'make the boys do it' type vid into a realistic study of their relationship and how Dean would respond to Sam's requests. I very nearly put all of Maichan's Sam/Dean vids in this list, but I decided to pick just one since they are all pretty similar. It was hard to pick.
Papa Don't Preach by fan-eunice and greensilver, Jack/Ianto
Jack's made up his mind, he's keeping his baby. This is the most adorable and squeeful thing ever.
X-Men: First Class
Never Tear Us Apart by Maichan2, Eric/Charles
Gorgeous, gorgeous use of many different sources to create a relationship through the centuries. Maichan says "Basically, this vid is an excuse for boys in cravats, suits, and uniforms."
