Hello!

Here is what I remember about the fic: Sam is with Jess, still studying at Stanford and they are mates I think. Then Dean shows up for some reason and turns out he is also Sam's mate. He struggles with the fact maybe even tries to leave? It can be a alpha/omega story but I'm not very sure. The fic turns into a threesome with Sam/Dean/Jess and I remember somewhere along the way Jess says something like "He is our mate"? Hope you guys can help me!
