Dean has been off on a hunt for roughly a week. It was Cas' turn to stay home. He'd do research for the brothers. As usual, he missed his boyfriend.
Cas: 
Dean: Fuck Angel, you're gorgeous!!
Cas: Thank you, Dean. I miss you. My erection is aching for you.
Dean: I can see that. You're making my jeans pretty tight with that picture.
Cas: Want you on your knees. Gonna fuck your throat... hard.
Dean: Anything you want. Let me swallow all your hot come!
Cas: Yes! then you can hold me down and pound my ass. Fill me up, Dean.
Dean: As Soon as I get home! Right now, I have to go... Sam is scowling at me. Guess he can't miss my boner. LOL Love you Sweetheart. Save that come for me.
Cas: Poor Sammy. Be safe. Love you too, Bumblebee.
