First a few questions, then a new dress code

As much as you wanted to just dive right in and fuck Lin senseless, you still can't quite believe what you are hearing. Even with your encounter with Mina earlier, you couldn't quite get over how casually she brought up that her orgasm to her assistant. That you were able to let go, but this...

"So you're really going to become my sex ****, just like that?"

"Uh, yeah," Lin replies, looking a bit confused.

"And you're fine with that?"

She frowns, "Well, I'll admit it's not exactly something I ever saw myself doing with my life. But you did tell me to do it, and I'd rather be your sex **** than say no to you."

"So if anyone else told you to be their sex ****..."

"I'd probably mace them," she interrupts, and you are suddenly very grateful that she's no longer carrying her purse, "Then call the police."

"Even if they were your friend?" you ask her. When she nods in confirmation, you continue, "So what makes it okay if I tell you to do it, but not anyone else?"

"Look, I don't know," Lin says with an exasperated sigh, obviously starting to get fed up, "I haven't really thought about it. It's just one of those weird things about life, like how it sometimes hails on a sunny day, or how a girl will feel like barking like a dog for a minute or two. Does it really even matter?"

Once again, you remember Charles' words: 'Don't overthink things'. Damn, how is one little suggestion so hard for you to follow? You decide that it's probably best to drop the subject before one of your heads explodes. Besides, you have an idea.

"You're right, I'm sorry," you tell her, "Let's just get started. First thing's first, strip down to your bra and panties."

"You got it," Lin says, undoing her belt. She then sits down and takes off her shoes and socks, revealing her dainty feet to you. Before you have much time to stare though, she stands back up and reaches behind her to unzip the back of the dress. She gives you a knowing glance, then pulls the straps off of her shoulders and lets it fall her body, revealing her matching white panties and bra. As you guessed, she has more of a bust than her attire would suggest, though they still weren't what you would call massive.

"You like what you see?" she asks you.

"I'll let you know when I see the back," you tell her.

Picking up on your intent, she obliges and turns around to show you her ass. It's small, but with a good butt you know size isn't everything. Confident that Lin won't protest, you give her a quick goosing to confirm that it's tight and firm, just as you like it. The Chinese girl lets out a small yelp and jumps in place.

"Something wrong?" you ask with a smirk as you back off.

"N-No," she replies, turning back around, "I just wasn't expecting you to do that."

"You better get used to it," you tell her, "As my sex ****, you're going to get groped a lot. Especially with a figure like that. Which brings me to my first directive as your master."

You pause a moment for suspense, then say, "From now on, this is all the clothing you'll need. If you want to wear anything other than a bra and panties, you'll have to ask for permission first. And yes, this applies for both inside and outside the apartment. I want everyone who sees you to know where you stand."

Lin fidgets in place uncomfortably upon hearing this, but nods and says, "Yeah, that makes sense. Plus it makes sure I can get naked at a moment's notice."

"Exactly," you say with a smile, "Speaking of, I think it's high time I saw those breasts of yours. Bra off, if you please."

Lin reaches behind her and unclasps her bra, then tosses it aside and puts her hands behind her back to give you a good view of her chest. Her dark brown nipples were already starting to stand at attention from being exposed to the cold air.

You walk forward and savor the view for a few more seconds, then start playing with her boobs, squeezing them in her hands and rubbing your fingers around her nipples to stiffen them up even more. Lin winces at your manhandling of her chest, but other than that takes it well, even giving you a genuine smile when you adjust your groping to be slightly less rough on her.

After a bit more playing, Lin ask you, "So, are you just going to play with my breasts all night, or is there something else you want me to do?"
