   Summary

   “Did you enjoy the show, Doctor?” Aventurine asks, voice still rough but the smile on his face entirely too satisfied.

   “Mm. He was rather rough with you,” Ratio comments, but he doesn’t sound particularly apologetic about it. It’s merely an observation, as if cataloging tonight’s events. He then examines Aventurine’s hips where just moments ago, fingers had dug into his skin. “I suspect there will be marks.”

   Aventurine tilts his head back to present the curve of his throat. “Then I suppose you’ll have to leave your own.”

   —Or, Ratio likes to watch Aventurine getting fucked.
