Sure, it can't be that bad. Can it?

Thinking it over, you suspect that she'll probably have you wear another piece of lingerie. Most likely the matching bra, or a cami top that might be visible through your work shirt. Well here goes.

"Sure Babe. What have you got in mind to add to my wardrobe, and what do I get for this surprise?"

"Well Sweetie, as you're still being so accepting. I want you to wear these two things in addition to the panties you're already wearing..."

Two things? You thought it would only be one addition, not two. What does she have in mind?

"...the first is the matching cami top to the panties. You'll look so cute wearing both, and I promise you'll find it worth it when you get home."

As she's saying this, she's walking over to her own dresser and retrieving the lace edged cami top. Still not super girly, but if it gets seen through your shirt, it'll leave no doubts that you're wearing lingerie. It's mostly plain though, there is only lace around the hem, and lace accross the bust.

"The other thing I want you to wear, is less obvious for the observer, but I'm sure you'll be feeling it all day..."

An with that, she's giving you another impish smile while she's looking at you. In one hand is the cami top she wants you to wear, and the other is a small pink jeweled butt plug in her hand. She's asking you to wear it to work for your half day. This definitely shocks you, as you tend to leak copious amounts of precum when wearing it. You leak so much your wife says that when you have it in, it instantly makes you wet like a good girl.

"...Now don't give me that look, you know I always have you wear it when you wear your panties. An as you're going to be wearing panties today, it only seems fitting to have you wear it like you normally do. Plus it'll have you and me, both hot, horny, and ready to go when you get home."

"Babe you can't be serious. I know you insist on me wearing the plug when I'm dressed in your lingerie, but I'll be at work. I'm not sure it's appropriate."

"I know you're nervous Sweetie, if you're worried about how much you'll be leaking in your panties. You can wear one of my panty liners to absorb the precum, and take a spare incase you need to change..."
"...if you're worried that I'll get upset if you say no, I won't. This is taking one of our kinks out of the bedroom, and while I promise the reward will be worth it... I won't **** it on you."

With her saying that final bit, she's still giving you the same impish smile she was before. You know you're safe to choose either way.
