You'll certainly try!

"First, you need to get this one ready," you say, reaching into her bag and retrieving her strap-on.

You toss it over to Mrs. Ling, who catches it reflexively. You nudge Tiffany forward and she stands in front of the mostly-naked Asian woman. You gesture towards the drawer with her gun in it, giving the woman a hint.

She accepts the situation- but surely doesn't like it- and gets down on her knees. She puts the fake dick on the Nubian girl with ease. You suspect that she has done this many time, albeit on herself. She gets it in place and looks over at you.

"What do you think I want you to do," you say sardonically, "Suck her dick!"

Mrs. Tan moans sadly on the couch while her Mistress begins to do what you say. She sucks Tiffany's strap-on like it is a real cock. Just for fun, you walk over the bound and gagged woman and remove her blindfold. You turn her head to the right, forcing her to watch.

"That's usually your job, isn't it? Oh and call me Master, slut," you say, taking out her gag for the time being.
"It's usually my job, Master," the woman replies submissively.
"Well, in the case, let's see how good you are..."

You unzip your pants and your cock pops free. You shove your cock in her mouth, surprising her a bit. Thanks to her submissive nature, however, she quickly accepts this and begins to suck. You 'feel' eyes upon you, so you look over at Mrs. Ling. She is staring daggers at you.

"You need to be taken down a peg or two still," you say, "Why don't you grab some handcuffs, Tiffany? I'll take your place."

The girl nods and walks over to the bag. You move over, pulling your dick from Mrs. Tan's mouth, and stand in front of the dominant woman.

"Suck it," you command, "If you don't, she's going to suffer."

She glares at you angrily, but does what you ordered. She sucks your cock with expert skill. You know how the Football Coach feels now.

Tiffany returns with some handcuffs and goes behind the woman. Without warning, she grabs her arms and pulls them behind her back. The woman doesn't fight, knowing what would happen if she did. Her arms are locked tightly together at the wrist by the steel cuffs.

"You're practically naked, you have your hands cuffed behind your back and you're still sucking my dick," you say, "So just admit that you're my slut."
"Never," Mrs. Ling replies, pulling her mouth away from your dick.
"Alright. It's time to fuck the fight out of you."
