Cass was a little shy. Normally, he had his demonic blood pumping, his mind racing, and he wasn't exactly at the forefront when it came to reason and control. Now, though?
He was going to remember everything, and that terrified him and excited him at the same time. Cass felt like his heart was going to beat out of his chest as they finalised the last details. Cass didn't think that sleeping with someone required so many checks and balances, but maybe it did when so many people were involved.
For example, Gideon and Lucian established that neither of them wanted to bottom. Edgar and Cass had to say out loud that they did want to bottom, and Cass had to say out loud that he wanted to do both.
It was embarrassing to Cass, but there was also something about saying it out loud that took some weight off of his shoulders. He wasn't sure what it was, but it was probably what kept him still as Edgar helped Cass undress as Lucian and Gideon quickly stripped off their own clothes.
