A/N: Written for the kink challenge at tw100. Please review; it's like candy to the plot bunnies.
Ianto couldn't remember mail ever being delivered to the hub. Yet today the postman arrived holding a package wrapped in brown paper with Ianto's name scrawled across it. He considered calling Jack – worried that it was a bomb – but decided against it. He'd never hear the end of it from Owen if he couldn't open the mail without Jack's help. Cautiously cutting open one corner, Ianto saw a folded letter and slipped it out to read. Ianto, Have fun with it. Martha. Ianto pushed aside the remaining paper and smiled at the bold red cap. He certainly would have fun.
