Advanced Deepthroat

"Good morning! Good morning!" Mr. Davis calls cheerily to you as you walk into his classroom for your Advanced Deepthroat period, recognizing him quickly since he was the instructor for your regular Deepthroat class last year. He was one of your favorite teachers that semester, truly passionate about his job, which is mostly shoving progressively larger and longer dildos into teenager's throats, teaching them not to gag.

"Open wi-... Oh! Good slut," he says, starting to command you to open your mouth so he can stick his fingers inside, but you have your mouth open and ready for him. Not only did you see him do the same to the student that entered before you, you're used to Mr. Davis gag checking you as you walk into the room from last year. You stare him straight in the eyes, giving him a wry smile as he jams three fingers down your throat and wiggles them around in a deliberate attempt to make you gag, but you take it all without a hint of convulsion.

Since your father took it upon himself to rid you of your gag reflex, calling in to work and spending a three day weekend mercilessly throat fucking you, switching to a replica dildo of his cock to continue stretching your esophagus when he was tired or spent, you don't think you've gagged a single time. He even made you sleep with the fake rubber penis hilted down to the model of his balls, securing it in place with a piece of duct tape until morning; and that was before you were drinking piss! Since then, the exact shape of your father's cock has been etched into your throat and there's nothing your teacher could do with three fingers alone that could possibly phase you. You passed his Deepthroat class last year with an A+ thanks to Daddy's help.

"I see you haven't been neglecting your studies over the summer, Sarah... Good job!" Mr. Davis declares, beaming with pride as a teacher as he rapidly works his fingers in and out of your throat more quickly than your average facefuck while you continue to maintain your smug expression. You wouldn't be allowed to take Advanced Deepthroat if you had even a hint of a gag reflex, but you're clearly enjoying it more than most, since you're still pretty drunk. He takes extra time practically punching you in the lips as he pounds your throat with reckless abandon while you try to hide the fact the it's making you orgasm repeatedly; trying to hide the pain/pleasure switch from him so he doesn't find out you've been drinking this morning.

"You're a model student as always!" Mr. Davis says as he pulls his fingers out of your mouth, slapping your ass and quickly sliding as many of his spit-lubed fingers as he can into your well-stretched asshole, easily sliding in all three thanks to your earlier anal DP this morning, and pushes you along to your desk as he turns his attention to the next slut that walked into the room, immediately stuffing his fingers into her mouth.

You beam with pride at the compliment, as well as the fact that the girl in front of you only managed to take two fingers when she was shuffled along. You can't believe how good of a day you're having, especially since the girl that entered just after you happened to be Britany; the bitch who always fights with you since her boyfriend has a habit of fucking you all the time, even though he usually gives her the resulting dose. You enjoy watching her take her gag test with fingers fresh from your asshole, extra happy you managed to fit all three, even though she passes the test stoically, as well as taking three fingers herself as she is pushed to her seat.

"Hey, Sarah!" Maria pipes up as you takes your seat in the chair beside her. The two of you deliberately took this class together, knowing that you'll be pairing up in advance so you made sure to sign up for the same time period as your best friend so that you could spend more time together. Maria's Boyfriend doesn't really get along with the nerds that you call your friends, so she spends most of the time you would usually be hanging out fucking him and his friends, so you hardly get to see each other any more.

"Sorry about Travis..." Maria laments. "I can hook you up with his friend Charlie, he's been looking for a full time cumdump! Then we can hang out all the time!"

You consider it a for a bit before gently rejecting her offer. Not that you hadn't considered actually getting a boyfriend, and Charlie isn't the worst option you could get, at least better than Bazzle, Kyle, or Matt, but having the three of them along with your father and brother has you practically drowning in medicine, even with all the wasted loads, which is way better than depending on the libido of one guy who will monopolize all of your free time, even as he constantly fucks other women at school. Your current setup keeps you as one of the smartest girls in school, holding your rather average intellect as the other women around you ****, even if you aren't exactly taking math classes anymore.

"Good Morning, Sluts!" Mr. Davis announces as he closes the door and begins his class, just as the bell rings.

"Good Morning, Master!" Everyone calls back, all of them knowing what he expects having passed his previous Deepthroat class. Most of the male teachers are referred to as 'Master' by the female students during school, especially class time, unless you need to refer to a specific instructor; which is another reason Mr. Dick assumed you were using the nickname his urinals affectionately call him as a secret code when you drunkenly slipped up this morning, forgetting the rule thanks to him introducing himself normally to your co-ed homeroom.

"As I'm sure most of you know, we'll be pairing up in this class," the enthusiastic instructor begins, pulling out a box of strap-ons with giant fake cocks hanging off of a leather harness. "Each pair will be assigned an esophageal dilator for use with your partner. You will be practicing extremely difficult fellatio positions on each other, following along as I demonstrate them on a volunteer, switching the giver and receiver halfway through class, so you both get a chance to practice taking it."

You knew all this already, happy to come prepared with your best friend so you don't have to worry about a random partner being too rough. Though as piss drunk as you still are, you're worried she won't be rough enough. You consider telling her to not hold back, but don't know if she would be cool about it.

"Do I have any volunteers to be today's demonstration?" Mr. Davis asks, barely able to contain his glee as he watches every hand in the room raise into the air, including your own. He surveys the classroom full of scantily clad teenage sluts eagerly vying for his attention in hopes of getting brutally throatfucked by him for an hour in the worst ways that he can think of, while rest of the class follows along, inflicting the same treatment on each other with fake cocks far larger than his own slightly above average member.

His slightly smaller 'esophageal dilator' makes being picked to be the example a highly coveted position, since whatever he does will be considerably worse when coming from your teammate with a strap-on, so the entire class has pulled out all the stops to get picked; most of them pulling out their tits and pushing them together or attempting various sexy poses in their chair trying to turn him on enough to get picked. You and Maria do the same, untying the string around your neck to free your respectable C cups from your halter top and pressing them together as Maria shows off by pulling one of her natural big tits to her mouth and sucking on her own nipple. You feel pretty good about your chances after his enthusiasm for your performance during the gag test earlier, hoping he values a good throat more than cup size.

Mr. Davis takes his time with his decision, allowing you all to debase yourselves more and more as he inspects each of you in turn, savoring the moment of his favorite part of the day and loving his job. He rules out the B cups or less automatically in his head, wanting a fat pair of breasts to twist mercilessly while he fucks his volunteer's throat, but he doesn't rule you out, happy to picture himself spending an hour destroying a pair of tits like yours while violently stretching out your throat.

He weighs his options carefully, openly rubbing his cock through his pants in front of the class.
