Mrs. Kincaid makes a good case.

"Make her lick my pussy," the Dean says, "I can give you a very good and logical explanation as to why you should too."
"Oh really. I'm all ears," you reply.
"It's simple- she's a slut who wants to get fucked and..."
"You bitch," Mrs. Ling says, "How dare you?!?!?"

Without saying a word, you fish Mrs. Kincaid's panties out of your bag and shove them in the Head of Security's mouth. You cover it with one hand and gesture to your other ****.

"Go on."
"As I was saying, she likes to get fucked," Mrs. Kincaid continues, "When her husband is out of town, she fucks the Gym Teacher. She does her morning jog, shows up at his on-campus Apartment and fucks the shit out of him."
"How do you know that," you ask curiously.
"I know this because I fuck him too. He spilled the beans while I was blowing him and, in turn, I got him to set up cameras in his place. I've got about four hours of video of this little Asian slut getting pounded like a nail."

Mrs. Ling yells through her gag, but no audible sound escapes. The combination of the garment and your hand muffles her almost completely.

"That still doesn't explain why I should make her do that instead of making you lick her."
"As someone with experience, I'll let you in on a little secret," she says, "If you really want to control someone, make them do something that they like. It makes them question why they should keep struggling."
"So if she likes to get fucked, I should fuck her. Likewise, if you like to exert control over woman, I should make her lick you out?"
"Exactly."
"Sounds good to me," you say, "Let's see if you live to regret telling me that."

With your free hand, you grab Mrs. Ling's nose and hold it closed. You can see her desperately holding her breath now.

"When I take this gag out, that mouth of your is going to be licking the Dean's pussy. Understood?"

The once-proud woman nods her head quickly, her eyes beginning to water. You let go of her nose and mouth, allowing her to breath again. She quickly spits out the panties in her mouth, causing them to land at your feet.

"That was a mistake," you say, "Just for that- I'm going to fuck that ass."
"Good," Mrs. Kincaid says, "This bitch loves anal. She practically begs the Coach to fuck her there."
"Shut up, bitch," Mrs. Ling says, showing a little spirit once again.
"Let's put an end to all of that talking now. Stay still."

You turn away from her and move Mrs. Kincaid over to a nearby bench. You untie her one arm and retie it in front of her. You finish her off by laying her back-first on the bench with her legs spread.

You return to Mrs. Ling and grab one of her lovely breasts forcefully. You drag her over- her tied legs making her steps awkward- and place her in front of the Dean.

"You're going to lick that pussy now," you say, "In exchange, I'm going to fuck you. As for you, I want to hear some nice, dirty talk. Let's all have some fucking fun!"
