"Extra credit, huh?" You smirk, your fingers gripping your thick cock and whacking the head against my lips. I fidget, spreading my legs unconsciously. My dress rides up and exposes my pale thighs.
I nod, my mouth parting, and I press my tongue out against your cock. You slap the head against my tongue and I hear you laugh softly.
"You handed your paper in late. That's an automatic fail."
"Please-'' I push myself forwards, nuzzling my face against your cock, "I can't fail, Sir."
"I don't think you understand just how much you will need to do to make up enough credit to pass, girl."
I frown, tears filling my eyes, "I'll do anything, please, Sir. Anything at all," I sniffle quietly, "I can't fail, Sir, please-"
Your voice cuts me off. "Show me what you can do with your mouth, and we'll see if we can get you an F at least."
I smile, my lips parting even more, wrapping around your thick head, my tongue swirls around the tip and I groan softly, my mouth vibrating against your flesh. Pushing my face down a little more, I take two inches into my mouth and suck hard. I groan, and lap at the underside of your cock, my tongue focusing on your shaft as I massage the tip of your cock with the roof of my mouth.
"You can take more than that."
I gasp around you, pushing down even more, half your length in my mouth and my lips stretched so widely around you. I try to smile, my eyes rising up to look at you. I moan again and wiggle my face, sinking another inch down your shaft.
"More, slut. Or do you want to fail?"
My pleas are muffled around your cock as I nuzzle my face against you, slipping lower down your length. The corners of your mouth curve into a smile and I suckle harder. I rise up and down on your cock. You're so thick, and my cheeks begin to ache. Pulling back until just the tip is inside my mouth, I swirl my tongue around your defined head, pressing my tongue against every ridge. I trace a vein in your shaft, working the tip of my tongue down to the base of your cock. Looking up at you, my face buried beneath your dick, you laugh and my cheeks redden with embarrassment.
"You look good with my cock on your face, maybe I'll keep you after all."
I whimper ashamedly, nuzzling my face against the base of your cock. My breath catches and I messily splutter against your balls, saliva dribbles down over them and I rush to catch the excess with my tongue, trying my hardest not to make a mess.
"Lower," you command, and I look up in confusion, my mouth pressed against your balls.
There isn't anywhere else that I can go. "Move your mouth down, lower." My brows furrow and I move lower, my nose nudging against you as my tongue slips over your balls, and beneath. I tongue the underside and slip my head down even more, closer to your asshole and then it suddenly dawns on me. I hear your laugh as the realisation plays out across my face.
"Oh, you do understand then," you say condescendingly as you watch my face sink beyond view. As you feel my tongue press against your asshole you moan, pushing towards my warm, wet mouth as I lap at your hole. My cheeks flush even redder and I close my eyes tight as I lick. Your fingers reach into my hair and for a moment I'm smothered by you as you press my face into your ass. Unable to breathe, I shake my head and sloppily try to suck in air, covering your ass in saliva. You suddenly pull my face forwards, smearing my spit all over my face as you bring me up.
"Please-" I whimper, gasping.
"Please what, whore?" You chuckle and lean down to spit over my face. I feel the warm liquid dribble down my cheek and I close my eyes tight to stop my tears from falling. I hear you laugh again, and your hand comes down to slap my cheek lightly.
"Sir-" I beg, my body shaking.
"You've barely earned your F, are you really going to quit now?"
I shake my head, opening my eyes. My mascara has smeared and my lipstick has long since been smudged. "I can't fail, please Sir," I beg, biting my lower lip nervously.
You smirk and tap the desk beside you. I blink and look up, watching as you push your papers aside.
"Hop up onto the desk and spread your legs. Let's see what you have to offer."
I flinch, rising up shakily. I push my ass against the edge of the desk and sit back, my thighs parting. You take a seat in your chair and move between my spread legs. I feel your fingers reach out and stroke the outline of my pussy. You murmur approval.
"Oh, a bare cunt. What a good girl you are." You laugh, and your fingers stroke over each full lip. Your fingertip presses the material into the gap between them and my wetness soaks in. You laugh comes louder. "Your cunt is betraying you, little girl." You poke the material and it turns slick beneath your touch. The pad of your index finger finds my sensitive clit and you start to move in tiny circles around it. Even with the material between your skin and mine, the sensation becomes unbearable within moments. My clit is so sensitive and it aches.
"Oh, please... please don't do that," I plead, my hips bucking against you.
You prod my swollen clit, "Why is that, whore?" I feel your fingertip press a little harder.
"It's sensitive," I gasp, "it's-"
Your fingers part and pinch my nub and I scream. I look at you and your mouth is curved into a grin.
"I think we should have a look," you say, your finger hooking underneath the edge of my panties and tugging them aside. As you uncover my bare cunt, you moan in approval. I'm slick with my wetness.
"Oh," I moan, my head tilting back as your finger presses against my clit once again, skin on skin.
"Hold your legs apart, slut."
I reach for my knees and pull my legs apart, holding them wide. My cunt is exposed, glistening in the light. My dress bunched up around my waist, my sopping panties pulled aside.
Your hand comes crashing down against my flesh and I wince, I yelp loudly and my legs come together. Shuddering, tears fill my eyes and I look down at you.
You're laughing.
"If you take 10 of those, perhaps I'll give you an E?" You laugh a little harder, and I shake my head in panic. "Fine, five more slaps. I'm being nice, slut. You should be grateful."
I nod, desperate to pass your course; I spread my legs again. My wet pussy is tinged pink and I know after 5 more it's going to be red.
"Are you going to count for me? Show me what an intelligent girl you are?"
"Y-yes, Sir."
"And are you going to thank me like a good girl?"
I bite my lip, trembling.
"Well, whore? Or shall I kick you out and fail you instead?"
I gasp, "Yes, yes, I'll thank you, Sir."
You nod, and my grip tightens on my legs. I close my eyes and wait. After a few moments, your hand comes down suddenly against my pussy and I scream out.
"One... one... thank you..."
