Deep Blue Ocean by suckerfordeansfreckles
Summary: Dean’s been in contact with supernatural creatures and people for all his life, as far as he can remember. He’s been working as a social worker for years now, specifying on cases that involve supernatural families.
But he’s never really… been with a supernatural creature. He’s never been with anyone, ever, for more than a night, really — not the relationship type, that‘s what he used to excuse it on.
But then he met Cas, on a case he worked with his brother, one in a cecaelia community in California. He met Cas, a cecaelia himself, and was kind of lost right away, because Cas was friendly, helpful, articulate and kind of brilliant. He’s also… gorgeous. When Dean first saw him, he kind of lost all breath and brainpower. They’ve been together for a few months now, but in all this time, they haven’t been intimate, haven’t really dared to go beyond their heavy make-out sessions.It’s especially hard again for Dean today, to not just devour Cas. To not just beg him for more.
