The Doctor sat there, handcuffed to the wall, watching River with a scowl across his face. A thought occurred to him.
"Hey! How come you have handcuffs?"
"Wouldn't you like to know?" she said, sending him a seductive smile from the chair, wiring herself up.
"Ooh KINKY!!" he joked, laughing uncontrollably.
"You always had a filthy mind," she told him, stopping her work for a moment "But…"
The Doctor paled.
"No." he went, if possible, even paler "No, no, no, no!! Oh, disgusting images!!"
I am so so so so sorry! I just couldn't resist. I wanted to yell that when he asked her why she had them. And yes, I had a filthy mind.
