Oh, I love fics where their commitment to each other and the question of their being exclusive become an issue, this was fantastic!

Insecure!Dean's pain was so tangible, your writing was amazing as always. And possessive!Dean is always a pretty hot thing in my book. :)

I'm admittedly not too keen on the idea of them having a threesome with a chick, but I did like that Sam only found the girl hot because she was like a female version of Dean.

Another great fic, thank you!
