Make Mrs. Devine pull double-duty.

You lift Kristi off of your cock and move her over to the couch. She starts to make out with Donna, who breaks off from kissing Jenni. Even when tied up, the trio can't stop their Sapphic display.

You move the chair out of the way and separate the trio. You see the vibrator between their pussies and take that away.

"You won't be needing that, you naughty girls," you say, "Because this Teacher slut is going to satisfy all three of you."

She gives you a dirty look, but doesn't exactly say 'no.' This slut will do what you tell her, even if she doesn't necessarily like it. She's a true submissive and she'll learn to love it.

You untie the ropes holding her to the chair and pulls Mrs. Devine to the center of the room. You take some of the loose rope and tie some around her chest. You loop it under her breasts and around her shoulders, forming a make-shift harness. You'll use this to hold her up for what you have next, since you're leaving her wrists bound behind her back.

You move her in front of Jenni and bend her over. The girl has spread her legs and seems to be inviting the woman's tongue. You press her face into the girl's pussy, which she immediately starts to lick.

"You should be wet enough for this," you say, shoving your cock in her pussy.

With one hand on the harness and another on her hips, you start to fuck her. She moans into Jenni's pussy, letting her real emotions slip out.

"How is she, ****?"
"She's good, Master," Jenni says, "She knows just a woman likes."
"Good. You have two minutes to make her cum," you say, "If you don't, you'll be punished."

The combination of your threat and, you suspect, her interest in making the girl cum from her tongue drive Mrs. Devine on. With just thirty-seconds to spare, she manages to do it.

"I'm cumming! I'm cumming from this ****'s tongue," Jenni exclaims.

She cums all over the naked Teacher's face. You don't slow down your fucking the whole time, giving her a reward for her actions.

When Jenni finishes, you pull the Teacher's face away from her pussy and move her, along with you, in front of Donna. You push her down into the girl's pussy and she starts licking.

"Since you're so good at this, I'll give you less time," you say, "You have ninety-seconds this time, ****."

You start fucking the Teacher even harder, really pounding her this time. She tries to focus on the task you've given her, knowing that you'll punish her if she fails.

"Tell her to make you cum faster," you say.
"Make me cum, slut," Donna says, showing her wild side, "Do it, slut!"

With not much time to spare, Mrs. Devine manages to find the girl's clitoris and sucks on it. This does the trick- thankfully for her.

"Fucking A- I'm cumming," she exclaims, "I'm cumming from this slut!"

She grinds her cunt into the woman's face as she orgasms. She even squirts a little from the stimulation given to her.

You pull Mrs. Devine's face away yet again and move into position in front of Kristi. The girl just came recently, so she's going to be more sensitive. Time to up the ante.

"You've got one minute to make this last **** orgasm," you say, "If you fail, I'm going to fuck your ass. Let's see what you've got."
