Mom speaks up.

"Please take me. Don't hurt her," Dee says, about to cry a little.
"Mom...."
"I accept. This first game is all about doing what you are told when you are told to do it. First..."

You order your man to connect Jenni's bonds to a rope hanging from a hook on the ceiling. He does so, forcing her to stay in place and watch what is about to happen.

You grab a large vibrating wand and go over to Dee, hovering it over her pussy.

"So this is very simple. If you cum without asking, I will fuck your daughter. Got it?"

Dee nods- as best she can tied up in a knot- and you turn the device on. You run it agonizingly-slow over her pussy, causing immediate stimulation. The MILF tries not to react, but it is nearly impossible.

You keep doing this for several minutes, seeing her composure break and smiling as Jenni can't help but watch. She could close her eyes, but she chooses not to.

Finally, Dee has too much.

"May I please cum...Master?"

You pull the vibrator just out of reach and give her your demands.

"You can only cum on one condition- if you tell me that you want me to whip Jenni."
"What?!? Never!!"

You smile and resume pleasuring her with the wand. You remind her of what will happen if she disobeys.

After a few minutes of this, Jenni speaks up!

"Stop it. Take me now. Do it!"

You smile and go over to her. You slowly undo the bikini bottoms and run the vibrator along her pussy, which is a little wet.

"If you cum without permission, my man over here is going to fuck the hell out of your Mom. Show them the goods."

He nods and strips down in between the two of them. His cock is, naturally, rock hard after all this.

"I'm sure that Mom loves big cock in her pussy, but I don't think you want to see it, do you?"

Jenni shakes her head and you start to pleasure her with the vibrating wand. She's even more sensitive than her Mom- that or she's just more wet and horny at this point.

It only takes five minutes before she reaches her breaking point...

"May I please cum...Master?"
"Only if you tell me to whip the hell out of your Mom over there. I mean, right on that pussy," you say.

Dee is shocked to see that Jenni doesn't immediately say 'no' right away. She seems to actually be thinking about this...
