The next morning, Sam woke up before they did. He heard something in Dean's room so he decided to go make sure his brother was okay. He never could have been ready to see what he saw when he walked in. Dean and Cas in the same bed. With Cas cuddling Dean. Sam looked away and shielded his eyes.
"Wha- You guys did not just… This is a dream. No, this is a nightmare," Sam mumbled to himself. He slapped himself in an attempt to wake himself up from this 'nightmare'.
Dean and Cas looked at each other, unsure of what to do.
"Um, I see this does not please you," Cas said, breaking the never-ending awkward silence.
Sam just walked away in shock to process what was happening.
Cas and Dean lingered together, giving each other soft kisses occasionally throughout the conversation. They decided that they were not going to try to change Sam's opinion. They were not even going to try to find out Sam's opinion. They were just going to explain to him the arrangement.
They found Sam researching and as soon as Dean and Cas walked in together Sam put his head down and averted his eyes, trying to be as invisible as possible.
"Come on Sammy, we need to talk about this," Dean started.
"About what, Dean? The fact that you and Cas are sleeping together and I'm just the third wheel now?" Sam retaliated.
Dean tried to calm him down. "Come on Sammy, you had to have seen it coming. It's like we've been making out with our eyes for a while."
"YOU AND CAS ARE SLEEPING TOGETHER!" Sam yelled. "DO YOU KNOW HOW MESSED THAT IS?"
"I am indifferent to sexual orientation and you know that. I am moving into Dean's room with him. We both find the memory foam relaxing to our backs." Cas interjected. "I don't need your approval. Dean may, but I don't."
