Haruhi looking through a box

You go downstairs and see Haruhi digging through an unfamiliar box. You call out to your new mistress, asking what she is doing.

"It's about time you finished up. This box contains all the sex toys you ordered me to come with. They've got some good things here if I do say so myself!" Haruhi continues to dig around the box. "There's something in particular I want to show you... ah! Here it is!"

She turns around to face you, holding what seems to be a strange looking black collar. You ask what it does, since you can tell that it is no ordinary collar.

Haruhi chuckles menacingly. "What I wanted to show you, ****, is this special collar here. I want you to wear it. I'm not allowed to put it only you, after all."

That sounds dangerous. Naturally, you ask why that is.

"Well you see, ****, once you wear this collar, I'm the only one who can take it off. What's more is that I get almost complete control over everything you do. I can make you do whatever I want, wherever I want, whenever I want. You'll be my **** through and through. Doesn't that sound like fun?"
