LIKE OMG I CAN'T BELIEVE I CAN'T FIND THESE STORIES ALL OF A SUDDEN. THAT'LL TEACH ME NOT TO SAVE!!!!

1) So the first story is a Mpreg. I believe it's Jared and Jensen. I remember that Jensen is straight and working towards a music career and is going out of the country and as a precaution he is tested. They find out he some (insert word here) who are men that can be pregnant and he apparently never took the test when he was young do to being sick. So the government takes him away, gives me some quick training then gives him to Jared. I remember Jensen couldn't handle the fact of being pregnant at all and went crazy even threatened to kill the baby if they brought it near him after it was born.

2) Second one I remember is that the Skinwalker that Dean and Sam meet the first time gets away  and basically becomes Dean. He says he loves Sammy and loves the brotherly bond that Sam and Dean share. He sneaks into the motel room pretending to be Dean, but Sam catches on and Skinwalker!Dean kidnaps Sam, and plans to become Sam's brother. Sam of course won't give him the pleasure.

Any help would be greatly appreciated!!! Thank you so much!!!
