OMG, that's the freaking most hilarious and sweet thing I've read in a long time. I love dialog-only fics when they are so funny and well written as this one, where the dialog just flows and you never want it to end.
I could quote the whole thing as my favorite part, but I'll restrain myself and just go with these lines:
"Great, now that you've shared, can I go back to sleep?"
"I once had a dream that you fucked me while levitating."
"I'll take that as a no."
"I more than make up for my shortcomings with my charming disposition and my huge cock."
"We can, and if you think back a few hours, you will remember that we did. But you have my body trained. I'm used to being woken up in the middle of the night and fucked within an inch of my life."
"Yes, but I never had to participate in witty banter for that."
"Believe me; you're not that witty at five in the morning."
"I miss the stalking days when you kissed my ass and worshipped the ground I walked on."
