Derek had left the door open and ducked down the hall to get another box from downstairs. When he returned to the playroom he stopped still, because Allison was standing there, looking at the brand new cage that had shown up today. Because that was his luck. He'd ordered it before Scott and everything had happened, and he'd been debating returning it.
For Derek, cages weren't tools of punishment so much as props for consensual fantasies, but he knew that Allison might not see it that way. He'd never seen the cage that Eterna had kept her in, but he could imagine it was somewhat similar to this one, large enough for a person to sit comfortably, though not stand, and thick vertical bars spaced wide enough to fit a hand or arm through--or something of equal thickness--with a door that swung open on heavy hinges, capable of being locked.
He licked his lips, standing awkwardly, and shook his head. "I should've closed the door," he muttered.
