"I thought I knew what that meant," Barry breathes, so deep inside Derek now that it seems impossible, but Derek is still whole beneath him, his face cracked open in pleasure, and Barry feels something within himself settle.

"I didn't know," he says, pulling out and out, nearly all the way before sinking in again with a sigh. "I didn't know anything before you." Barry watches Derek's face, and even though Derek only reacts, even though he only whines and clutches at him and sighs, Barry feels a sense of guidance. He needs to make Derek feel good. He needs to give Derek everything Barry's ever felt beneath him, and Barry watches him intently, matching his thrusts to the expression of bliss on Derek's face.

It's incredible. He's incredible. "Look at you," says Barry in awe.
