He held a coin out on his palm and her smile faded. Not a Galleon, not a Sickle. Not even a Knut. It was a Muggle coin, small, round, and bronze. Pansy stared at the coin, then stared at his face. He sniffed. "I'll be back in two weeks. If you're any better by then, I'll see about giving you another go." He bent, snapped his fist shut on the coin, and grabbed her hair. "Maybe then you'll earn this, whore."
Pansy watched him leave. She slumped against the chair with a smile, her eyes shining like diamonds.
One of the things I sometimes do in this exchange is after I've read a fic or looked at the art is to go read the recipient's sign-up to see how the mystery author or artist interpreted the prompts. Because this fest is so open to such a range of lesser-loved characters, it's always amazing to see such a variety of requests come to life.
I love how you took scarletladyy's prompts and created an excellent example of what BDSM is like, and why BDSM is not synonymous with abuse. The sex acts are rough, but it's all consensual, and both Marcus and Pansy get what they want from the encounter.
