He was torn between dying of embarrassment, the feeling familiar from Smallville, and the times tricks like this had been played on him before, and just wanting to curl up and sleep.
You described amazingly Clark’s feelings in the first part of the story. And the memory about Smallville - I loved it!

He carefully listened in on the conversations around him, careful not to truly eavesdrop - his Ma would never forgive him if he did!
Awww, Clark still thinks so much what his mom would say, that’s lovely. *Hugs him*

"Hey, Bru...!" He blinked.
Standing next to him was Superman.
OMG, I had to laugh. That was such a wonderful surprise! :)

"I wanted to check up on you. When was the last time you slept?"
Clark stared at him. "Uh..."
"That's what I thought. From now on, you're on holiday."
Bruce checking up on Clark was amazing. That was so nice and sweet. :) And the Clark reaction! *Gigles and Hugs them both*

I enjoyed this story. Thanks for sharing. :)
