"So, what can you do to make me happy while we wait for your friend," you ask Ms. Devine.

"I'll do anything you want- as long as you don't tie me up."

"Well, that is a tempting offer. However, there is no way that I can leave you untied when your friend arrives."

"Why not? I already promised that I'd be good."

"That's not enough. There will be two of you and only one of me," you reply, "I can't trust that you two would refuse to try anything."

"Please- I promise!"

"No. However, depending on what you do, the amount of tying up that you get may be lessened."

"So, if I obey you and make you happy, you'll only tie me up a little..."

"Right. If, however, you keep arguing with me over that, I'll place you in a super-tight hogtie on the floor," you say in a direct manner.

"...I'll be good, master."

"Master- that's a nice touch. Just for that, I won't tie your elbows so tight. Keep it up if you want to stay happy, ****."

"Do you want me to suck your dick," Ms. Devine asks you softly.

"A tempting offer, but not right now," you reply, "I'd rather you ask me again when I get you some more company. I want them to see you ask me and only then will I make my decision. For your initiative, however, your knees will remain untied."

"Thank you, master. Do you want me to do naughty things with my friend when she gets here?"

"Yes, yes I would. Good job, ****. I'd love to see you two tied chest-to-chest and make out," you say, "I guess that spares you an elbow tie altogether. Speaking of which, I think that it's time for the ropes to come out. Be still and I'll tie your hands in front of you."

"Yes, master."

You reach into your bag and pull out a few loops of rope. True to your word, you tie her hands together in front of her. You make sure to place the knot at a point that she can't reach, however.

She puts her legs in front of her while she sits, allowing you to tie her ankles together tightly. The knot is also out of place for her to reach. She's compliant, but there's no point in taking a risk.

"Now, normally a **** like you would be gagged, but I need your mouth open for a while," you say in a commanding voice, "Understood."

"Yes, master."

You take a moment to check out your half-naked and compliant ****. The busty teacher's olive-colored skin is shimmering with a light coating of sweat due to fear. She is clad only in an orange bra and matching slip. Her sumptuous breasts are a sight to behold, pressed up firmly by the material.

You stand her for a moment and pull the slip down. Why not, you figure, since it's still her underwear. Naturally, she doesn't fight you.

This reveals her matching orange panties, though they have a black fringe around the outside- the same as the bra does.

"Now then..."

Your next command is cut off by the sound of someone knocking on the door. You look at Ms. Devine.

"It's her," she says softly, "What do you want me to do, master?"
