A few minutes

Just a few minutes later, encouraged by Kim's ass and Sara's skilled hands, you start moaning. "Please, please!"

"What are you saying, Professor? Please stop? Please keep going? Doesn't matter. I'm going to do what I want, no matter what you say."

You just keep moaning. And moaning. And, all of a sudden, just before you were going to come, Sara takes her hand off of your cock. You close your eyes, moaning, gripping the arms of your chair tightly. And Sara leans down and just breathes on your cock, a soft, warm breath.

And it's enough! You moan one last time as you ruin your orgasm all over the panties Sara was just using to stroke you.

"Thanks, Professor! If you hadn't denied being a panty perv, I might have let you have a real orgasm! But you lied, silly man. Open your mouth!"

You see her holding the panties you just came in, and you shake your head, "No! No!" But she just grabs your nose, forcing you to open your mouth just to breathe. It only takes a moment for her to pop her panties in your mouth, too. And just another moment to pull out the duct tape and ensure you can't spit out your come covered panty gag.

"Taste good, professor? I only came in those once today, but I think you made a much bigger mess," Sara laughs.

And now, as you struggle to breathe with your mouth taped, you start to feel quite worried. The girls just laugh at you, circling around and taking incriminating photos.

And then Kim comes up with a naughty idea!
