If you don't want to buy multiple copies fo the game and you both ahve your own PC's, it should be easy to do (and it's not against terms fo service since only one person can play the game at any one time).
Just install Steam on each PC. you cna then log in with the same account on the PC where you want to play. When someone else wants to play, you'll have to stop playing and log off so the other player can have his turn.
As for saves, you don't have to disable cloud saves. In fact, don't. this way you can hop on either PC and continue playing your game. Just make sure you guys agree that your saves will be NAME - whatever and you're set.
Obviously you'll have to make sure not to forget to save your game with that named slot before quitting out as auto-saves and quick saves will likely be overwritten.
