Wow! I love love love this! The imagery you've created here is very strong with the rain on the window and Brian's kisses.
He tells me that it's been too long since he's tasted me, as if it's been days and not merely hours. Or he whispers that he wants to come inside me again. Or feel me inside him.
That is my favorite part. I can really see Brian saying that.
I really enjoyed reading this because even though it's short, you've managed to make it interesting with their interaction. Their emotional and physical connection really shows through here, which is difficult to do in so little words. Bue you have. I love it. Thanks for writing it.
