Where Shamy had an Amelia and the Time Travelling Physicist, Cooper roleplay sex.
Another year, another birthday celebratory sex Sheldon will surprise Amy with.
This year Sheldon has something in mind. It was a couple of months since he discovered Amy's fanfiction of them.
He reads the story and even diligently waits until the next time Amy updates. He can't help it. Amy's a very great and creative writer.
Tonight, he will be revealing to Amy he knew of its' existence. Maybe even reenact a scene for the coitus portion of the night?
A/N: What do you think Amy's reaction will be with Sheldon's birthday surprise? If found a story with similar plot or based a story from this prompt— I'm shamyshenanigan on IG! I'd love to read the story.
