Ianto was surprised when he arrived at the hub that evening and found it empty. Jack had called him at home and had asked him to come in, saying it was urgent.

Now here he was, standing in the empty hub. No sign of anyone. Just a mysterious box on his desk.

He opened the box. When he got a look at its contents, his eyes grew wide.

Inside was the promised red UNIT cap, a black leather codpiece, and a black leather riding crop, along with a folded sheet of paper. Ianto opened the sheet of paper and read its few lines.

I've been bad and need to be punished. Put these on, and cum into my office.

-Jack.

Ianto quickly shed his clothes and donned the codpiece and cap. He took the riding crop in his hands and made his way to Jack's office.

Jack was already in position, on his hands and knees on his desk, delectable arse up in the air.

"Oh Ianto." Jack breathed when Ianto walked in. He really cut a dashing figure in that cap and filled out that little leather codpiece delightfully. Jack shivered in delight, glad that Ianto was going along with this latest little game.

"So you've been bad huh?"

"Oh yes, so bad."

"What did you do?"

"I was jerking off at my desk today. Watching you bend over."

"Is that why you kept dropping pencils all over?"

"Yeah."

"Now Jack. That is not appropriate office behavior. Clearly you will have to be punished."

"Oh yes please. Punish me Ianto."

"I think you mean punish me please Mr. Jones."

"Oh please punish me Mr. Jones. I've been such a bad boy."

The riding crop lashed through the air and landed with a crack onto his bare rump. Jack drew in a hissing breath. It stung, but oh in a good way.

Ianto warmed up his arse with the crop. Each stroke made his cock twitch even harder. He was already leaking all over the desk.

When his arse was a nice shade of red, Ianto put the crop down, and wrapped his hand around Jack's cock.

"You've been punished enough. Now you get your reward."

He didn't even have to do much. The spanking had turned Jack on so much that after a couple of quick strokes, he was spilling his hot seed all over Ianto's hand.
