Still bucking and moaning, Ms. Victoria snaps out of the handcuffs and tears her feet free of the stocking ties, yanking the vibrator out of her abused pussy and falling to the floor in a pool of her own cum. Her dark, hateful eyes find yours, but you don't take it seriously. What's she gonna do in her state?
"Alright class, hopefully you've learned the limits of human pleasure today in chemistry class, and all thanks to our wonderful model Ms. Victoria. Bet your boyfriend doesn't make you cum that hard, huh?" You taunt, your ego rising with every laugh from your classmates. That's when you make the most foolish decision. You turn you back on her and mock bow to the large crowd of jeering students, who only grow louder in what you assume to be reverence of you.
Its not.
Its due to their view of Ms. Victoria coming up behind you with the same handcuffs you had used on her. Before you know whats happening, she has you face down and ass up, your skirt barely covering your black lacy panties. "Seriously Ms. Victoria? You're completely spent and shaking, still nude and showing off your bouncy tits and you think I can't beat you again against these flimsy handcuffs?"
She covers up her tits with her left arm but smirks down at you. "Try." You yank at your hands, expecting to hear the plastic snapping and your hands free, but as you look down you realize shes replaced them with real handcuffs. You're screwed.
She walks back around to the front of her desk where you bubble butt is wiggling in desperation, and places her hand on your lower back, forcing an arch. You take this opportunity to kick out at her still nude and sensitive body, and slide your toes up her soaking slit. She moans and her knees buckle, driving your toes deeper as you wiggle and kick. She collapses on the floor, and you think you've won again.
"C'mon Ms. Victoria. How do you think you can beat after that show you put on a second ago?" There's no response, and you figure she's recovering from your erotic kick. Until she cuffs your feet down to the sides of the desk. Shit.
"Well Ms. Kelly," she says, tying a robe around her body, "class time is officially over but anyone is free to stay and watch for the next hour or two." She says gleefully.
"Hour???" You gasp. What have you gotten yourself into? You don't hear anyone leaving.
"Nobody's leaving? Great. Alright Kelly, hopefully you don't have any plans this afternoon." She says, sliding your skirt and panties down your legs. Everyone's already seen your bare pussy, but this **** position has you squirming.
"Now class, were going to learn about a little different type of pleasure today. Or rather, a different hole." You gasp. In fact, the whole class does. Anal?
"No no no please Ms. Victoria, I've never done it....in the ass before." You say shamefully. The class titters and you feel yourself blushing at the confession.
"No worries Kelly, we're focusing on the urethra. Say Kelly, when is the last time you went pee?" Ms. Victoria asks.
"About two hours ago..." Your voice trails off. She can't be serious. And now that she's brought your attention to it, you have to go. Bad. "Ms. Victoria, please let me go. I'll let you do whatever, just let me go to the bathroom, please." You beg.
"No. I will let you go, but you'll do it here. In case anyone is unfamiliar, when you pee it comes out of your urethra, separate from your vagina, although it can still feel pleasure. In fact, I have a very thin vibrator for this purpose." You feel you muscles clench, holding in your pee. This cannot be happening.
"No Ms. Victoria don't do this. I really have to go. Please" You beg, your voice as **** as ever.
"Oh I know." She whispers, and you feel a tiny vibrator massaging the muscles holding your pee from spraying out. Its weakening them, and you're worried it won't be too long before they give up entirely.
Not only that, but the pleasure builds up a separate tension in your stomach, and you can't tell if the pressure on your bladder or your building orgasm is worse.
"C'mon Kelly. Let go. Show this class something new." You can't let this happen. You clench harder, and Ms. Victoria feels it. She slaps your ass, and in the shock you unclench your whole lower body.
You piss the hardest you have ever in your life, while simultaneously cumming. You whole body shakes in pleasure and relief.
