A Popular Fence, With a Shameful Secret

DING-A-LING the little bell above the door jangles as it opens. You look over at the door and your heart sinks. One of your least favourite people has just entered the shop: Detective Amy Santiago of the 99th Precinct. She's not wearing NYPD colours, instead opting for a mint-green blouse with a plaid skirt, high-heeled boots and a studded choker with a key dangling from it. She has a streak of blue in her hair, which is flowing freely as opposed to her usual ponytail. Your eyes are almost popping out of your head at this point, unable to believe that a beautiful character from one of your favourite TV shows is standing in front of you. She looks very different in person than she does on the show.
Maybe she's undercover. You think to yourself.

Detective Santiago quickly scans the store to make sure there are no customers. There aren't, it's 5:45 on a Friday afternoon, the types of customers you're likely to get have all finished their daily business by now. Santiago flips the sign on the door from OPEN to CLOSED then locks the door behind her. Despite her stunning looks, some part of you is not happy to see her, and you're not really sure why. She struts over to the counter.

"So, what have you got for me?" Santiago asks brusquely.
"I...erm...I don't know what you mean." She lets out a long sigh, and fingers the key around her neck.
"Let's not do this dance. We've done this enough times now that you know what I expect." You're not really sure how to react to that, so you just remain quiet. It must make you look gormless, because she smacks you, hard, right across the face.
"Stupid bastard." She mutters. "I need information. Have you forgotten about our arrangement? No, I don't see how you could." Her eyes flick down to your crotch. It's then you realise something is very wrong. Something definitely does not feel right. You grab at your penis and find that it's encased in something hard. You hear a soft CLINK. Then it dawns on you.
SHIT. I'm locked in chastity. All of a sudden, you know what the key around Santiago's neck is for. She's been watching you this whole time.
"That's right. You remember how this works now. You're the #1 Fence in the city. You rub shoulders with all the top criminals, so, you give me something I can use, and I unlock you for the weekend. You don't co-operate, and we do this the hard way."
"What's the hard way?" You ask. It was a stupid question, you get another slap for it, and she spits in your face. Santiago is getting more and more irate, she now gets very close to you. You can smell her perfume, it's masculine and cloying.
"The hard way is: I make you swallow this key, then edge and ruin you until it comes back out. I also have a few uniformed patrols swing by this area. I'm sure that would scare off your criminal clients. Or maybe I'll just feed you to Rosa." She says, pensively, as if she's genuinely weighing up the options.

"So, what's it going to be, are you going to co-operate, or are you going to stay locked?"
