His is caged! (Small, Red Metal)

You feel the metal contraption around his cock before you look down to see better. It's tiny, hes in a small metal cock cage with bars, his cock straining against the few exposed bars, the whole device is red and looks like a standard key that you already have in your possession.

He giggles at your surprised reaction, "he he Sir, you know the staff isn't trusted to be left uncaged! Only a family member is allowed to unlock it when they want to play. I know you have one of the keys sir..." He almost purrs, leaning forward to snuggle into the side of your neck and gently kiss, all while still stroking your cock. "If you freed me for a little bit, we could have some real fun. wouldn't that be nice, sir?"

Between the stroking you manage to gasp out, "Why red?"

He kisses you more around your neck while speaking between them, "A reward, maybe", kiss, "I've been here a few years now," kiss and tighter grip, "After training, I've never been let out," sigh, kiss, "I've only served, no mouth, ass or pussy for my cock", long slow stroke, "let me out to play"

This little sissy maid is obviously trying to seduce you to get what he wants, and you are sure its more than just the key to his cage, but whatever that may be in the end you are distracted and can't think. Even if you realize that much, you cannot deny he's doing a great job to convince you.
