He picks Maria

The horny instructor stops on Maria, enticed by the thought of crushing her meaty globes with his hands, but what puts her over the top is the strip of duct tape starting just below her clit that she's stroking and stopping just before her asshole, the sign of either an overprotective father trying to protect their precious daughter, often a virgin, or a jealous boyfriend saving her cunt for himself. Either way, he wanted someone other her to be upset if he manages to ruin a spectacular pair of huge naturals like Maria's.

"Maria? Please come to the front of class. Everyone else, please find your partner and grab a harness from the box and decide who will wear it first."

You groan along with the rest of the girls in class as Maria happily bounces to the front of the room to be stripped and groped by the teacher; the blow hitting you doubly hard as he just stole your partner. You look around the room frantically and your blood runs cold as you spot the only other girl in class that doesn't have a partner.

You and Britany scowl at each other, knowing you'll inevitably be spending the next hour with your worst enemy, both secretly excited to get the chance to inflict whatever pain the teacher prescribes onto the other. You're still drunk enough to be slightly excited to have someone hostile enough to make you cum. Maybe this won't be so bad after all.

"Hey, Bitch. Who's goin' first?" Britany asks flippantly, trying to act like she's not bothered as she holds the strap-on she pulled out of the box between you. She can't do anything to you that you won't be doing right back in about half an hour and it's not like either of you want to be partners.

"You wear it, I'll take it," you say, trying to be cool about the fact that you need to go first to still be drunk enough to enjoy it, already feeling most of the effects start to fade and not wanting to get brutalized sober; plus it might be nice to take out your withdrawal headache out on the stuck up cheerleader's throat. Britany shrugs, stepping into the harness and pulling the fake penis up to her pelvis, smiling as she feels the power of having a giant black cock.

"Alright, sluts. Let's start with an easy one. Maria, please lay on your back on my desk, the rest of you do the same." Mr. Davis commands, not actually waiting for her to even start climbing onto the desk before picking her up by a rough handful of hair and one of her huge tits to throw her onto his desk like a piece of meat, slamming her down with a loud thud.

"Yes, Mast- AH! GUGH!" Maria shouts, hoisted into the air before she can finish replying and crying out as she suddenly makes impact with the table. You can tell she must be sober by her cries of pain rather than a sudden orgasm, writhing around and trying to recover as the teacher begins slapping her in the face with his cock without letting go of the breast he threw her with, which is a shame since you're pretty sure her boyfriend feeds her piss, so she's likely going through withdrawal as well.

None of girls are strong enough to lift their partner into the air like their expert teacher, used to getting his students into position as quickly as possible, but most of them are happy to try; fortunately including Britany, who grabs your hair and one of your exposed breasts and yanks will all her might in an attempt to throw you through the air. You are barely able to stifle your loud moan, drown out by the cries of pain from all the other girls that were attempted to be thrown.

"Are you fuckin' pissed?" Britany asks you in a terse whisper as she's the only one who noticed your reaction. She almost considers turning you in, since she hates you and all, but now that you're so close to her face, you can tell she's barely holding it together herself. The glazed over expression on her face and slightly slurred speech gives her away enough, but you can tell from the strong, delicious smell on her breath that either her boyfriend used her as a urinal between classes or she drank from a piss bottle in her backpack just before coming to class, to soften the blow of what was going to happen here.

You likely drank significantly more than her today, having been ****-fed more today than you normally get on all but your most busy mornings acting as the house urinal over the summer, but in your experience the effects last about two hours and you're starting to come down pretty bad having had an entire class since your last drink, while Britany is fresh, she'll definitely still be drunk by the time you get to use her. Regardless, stuck in the same boat together now.

You've hardly had to go the full two hours nearly at all over the break, your wonderful father and brother overhydrated themselves enough to take care of your needs by themselves, and that's not to mention any visitors or friends that would frequently stop by just to piss down your throat. Even in your sleep, often after your brother pinches your nose while leaving his cock blocking your airway until you pass out, since he enjoys freely using your holes while you're ****, you basically never had to go the full two hours before someone finds the need to poke the head of their cock between your lips and relieve themselves, barely waking up as a stream of piss hits you in the back of the throat to let you know to start gulping before your pillow gets wet. You don't bother to notice or care who is filling suddenly your mouth with your favorite **** in the middle of the night, especially since everyone in the neighborhood knows your window is unlocked and you encourage the late night visitors.

Until this morning where your father deliberately locked your window and **** you to waste the delicious urine he poured into your mouth by letting it fall into the toilet for the first time in months, rather than going into your stomach where it belongs, you practically forgot the withdrawal was a thing that happens; happy to be used and abused all summer long without having to worry about feeding your addiction thanks to your caring family and friends.

Now, as you climb onto the desk in front of you, laying with you head over the side and staring down the barrel of a dildo bigger than any cock you've ever had, wielded by a bitch that hates you, you begin drunkenly trying to calculate the time you have left and hoping it's enough to last through the whole ordeal. Britany begins slapping your face with the fake cock as she roughly twists your nipple like your teacher is currently doing to Maria and you're instantly too lost in orgasm to do the simple math, but happy it isn't quite yet.

"I know this is the first time most of you sluts have done something like this, so we'll start slow for the benefit of the giver and I'll try to explain everything slowly." Mr. Davis starts in his kindly voice as he grabs Maria's lower jaw and forces her mouth open by squeezing her cheeks while yanking her chin. "Even if her mouth is already open, you're gonna want to help your partner get wide enough to accommodate your girth without scraping her teeth on the shaft. I know you can't feel it, but it's important for real world application to ensure no contact is ever made. When you think you're ready, carefully insert the head and line it up with the back of her throat."

Britany tries pulling your lower jaw as the teacher demonstrated, but drunkenly yanks it in the wrong direction, forcing you to stifle a moan as you open your mouth as wide as possible anyway, but at least ten other girls cry out in pain to cover it up as they are **** open at the same time. Her weak grip doesn't feel as good as when John does it with his powerful manly hands to make room for his giant cock, the closest you've had to this size before now, but the fake one is more soft and rubbery than his iron pole, so you're more worried about hiding your orgasms than taking the whole thing. The pissed blonde cheerleader obliviously clips your teeth with the giant head as she pushes it inside, while you instinctively run your tongue around the huge intrusion as well as you can with the little space left in your mouth, even though there's no one feeling it.

"Now, once you're ready, you're going to want to firmly grab something to brace yourself for insertion, usually the neck or lower jaw, but I find that helps to loosen the larynx if you use the breasts or nipples for leverage as you push forward, squeezing or twisting them harder if you have any difficulty fitting inside."

"Gwah!....GAAHKKKK....GRRRRKKKKAAWWWKKKK....KKKKKKNNNKKKKK.....kkkkkkkk" *SLAM* Maria screams as Mr. Davis brutally crushes her massive tits, the meat bowing out sharply between his fingers, yanking them towards himself as he slowly slides his thick eight and a half inches down her throat, aided by her cries of pain, taking his time sliding the entire length inside, punctuating the fact that he's fully hilted by crushing her skull between his pelvis and the edge of the table with a sharp thrust that echoes through the room.

"Of course, if your partner isn't as... blessed... as Maria here, you can always use just the nipples to get roughly the same effect." Your deceptively cruel instructor says, pulling out of her throat and repositioning himself in her mouth with the head at the entrance like was before, releasing his **** grip on her tits and switching it to her erect nipples.

"NRRR...NRRR...NNN...GGKKKKNNRRKKKKKKKKKkkkkkkk......kkkkkkk....kk...." *SLAM* Maria attempts to protest as her teacher twists and pulls her nipples towards his body, going deliberately slowly again as he thrusts himself inside. She's had to deepthroat cocks and toys much larger than his respectable size just to place in the Advanced Deepthroat class, but her diligent instructor is attempting to simulate the difficulty his students will have using the giant dildo that's quite a bit bigger than him, smashing her head again at the end with another hard slam.

"MmmmmMMMMLLLMMM....MMMMMMLLLLLMMMM...MMMMMMkkkkkk..." *SLAM* You moan, making noises significantly different than your tortured best friend, as Britany chooses the breast crushing method and begins stretching your throat beyond all reasonable capacity, sending you into absolute bliss and aiding her entry with an orgasmic moan rather than screams of pain. The ending slam makes you cum so hard that you have a massive squirting orgasm all over the desk, convulsing and shaking involuntarily through your legs as pleasure takes over your brain.

"Ah, if you're partner is having trouble keeping still, you can apply pressure to the abdomen to help keep them steady" Mr. Davis helpfully offers when he notices you kicking your legs, demonstrating on Maria by pushing his fist just below her belly button, deliberately aiming for her uterus as he pushes down with all his might, even though she isn't struggling like you are. Her tan legs do start kicking for a second as he twists and grinds into her sensitive womb, then suddenly stiffen to a locked position, quivering with pain as her teacher continues deliberately trying to scramble her eggs.

Britany and several other girls follow his example, causing you to have another massive squirting orgasm as your uterus gets brutally crushed, quickly managing to get you under control as your legs stiffen, quivering with pleasure in a similar way. Mr. Davis almost begins to suspect something as he notices your squirt, but fortunately your bully is pressing your bladder as well, filled nearly to the brim with the former contents of several other boys, forcing you to fire out a high-velocity stream of urine, somehow arching it perfectly to hit the face of the girl who was sitting in the next row, as well as crotch of the owner of the fake cock being stuffed in her throat, fully soaking the entire length still being slowly worked inside the slut that's less talented than you.

"Hmm, yeah I guess that can happen sometimes..." Your teacher muses, mercifully releasing his pressure on Maria's abdomen before she has a similar accident, blaming himself for yours since he made her press on your bladder so hard. He wonders to himself if it breaks the piss drinking rules to **** you to suck up the mess you made, since it's just inert girl pee, but figures he can decide later since the command is the same. "Please make sure to clean that up before you leave, Sarah." He signals that the girl with the wet dildo can continue, sliding a small amount of liquid down her partner's throat to be processed by a third person in a single day, then slamming her damp crotch into her face with a slightly **** impact than your teacher or Britany.

"Okay, everyone! Once you're fully inside, you're going to want to help your partner get used to holding such a large object in her throat, so you can help work out any knots or tight spots by massaging her neck, like so...." He teaches helpfully, continuing his lecture as though nothing happened after waiting to make sure all of his new students have hilted their fake cocks and completed the final crushing slam, then firmly grabs Maria's trachea and begins openly stroking his penis inside her neck without moving from his spot pinning her skull to the edge of the table, leaning forward and pressing harder as he pretends to give her a massage, openly masturbating himself in front of the entire class while still lodged in the twitching teenager's tight esophagus.

You receive a pleasant tracheal massage from Britany, nowhere near enough to make you cum with Brittney's weak grip strength around her fake cock. Your father can jerk himself off to completion several times in a row without moving a single inch on the rare occasion he gets ahold of some Zanalfil, wanting to fire off into your stomach as directly as possible to make sure you don't lose a single drop of his precious medicine as he digs his fingers deeply into your neck, trying to get a more firm grip on his cock as he crudely uses your esophagus as a cheap sextoy; not to mention John, who uses both hands to violently jerk himself off with your throat. The bitchy cheerleader's light squeeze almost relaxing in your drunken state, you just wish the cold rubber dildo had the ability to deliver you the hot stream of piss straight into your belly you're craving, to refresh your buzz like Daddy would.

"...Nguuuuk..." *SLAM* "...Nguuuuk..." *SLAM*"...Nguuuuk..." *SLAM*

"Once you're pretty sure your partner is comfortable enough, you can begin giving a nice slow thrust to start with, just make sure you're completely inside when you reinsert by pressing firmly against the edge of the table." Mr. Davis instructs, already demonstrating on his volunteer by pulling himself out of her throat extremely slowly, then slamming back down in an instant, repeatedly smashing her head with concussive ****. Maria seems to out of it to even react much more than a jolt with each impact, mostly from the shockwave traveling though her body as she barely clings on to consciousness, the tremendous pain keeping her from passing out entirely.

"...Nmmmmm..." *SLAM* "NNNNNNnnn........ Nmmmmm..." *SLAM* "NNNNNNnnnkkkk........ Nmmmmm..." *SLAM* "NNNnnnnnnnnggkkkkkk...."You moan, trying to hide it as your drunken partner slowly slides the giant black dildo out of your throat, but unable to control the resulting orgasm from her pelvis crushing your head into the table.

"...Nguuuukk..." *SLAM* *SMACK* "NNNN!.......Nguuukk..." *SLAM* *SMACK* "NNN! .......Nguuuk..." *SLAM* *SMACK* "NNNNNNnnnNNNN!"

"Don't forget to mix it up with anything you can think of to trip your partner up during training! Especially if you can think of something that someone has done to you in the past that tripped you up during a similar situation. This could give them valuable experience in dealing with unexpected scenarios they might encounter later in life, outside of practice, so don't hold back!" He helpfully quips, beginning to add a sharp smack to her big tits as they jiggle fiercely after each jarring impact, alternating sides, smacking the left side of one huge melon, then the right side of the right pendulous orb on the next thrust. He enjoys watching them violently flop from side to side as the bright red welts begin to form then deepen, to get more of a reaction from the lazy cunt and blissfully feeling her cries of pain as they vibrate his cock in her throat.

Britany begins slapping your less impressive chest around as she continues slamming your head into the table, already finding it easier to control yourself as it begins feeling less and less pleasurable. If it was John or one of your family members, they would be able to continue smacking your tits and slamming your head hard enough to make you cum, but the piss drunk cheerleader isn't even doing a very competent job at skullfucking you, frequently falling out of your mouth and scraping your teeth as she forces it back inside, not able to feel the pain that would cause a real man.

"If you brought along any toys or clamps from home, now would be a good time to bring them out, to add a bit of a challenge for your partner as we ramp up the difficulty." Mr. Davis says as all of his students get on the same page, abusing the sensitive bodies of their classmates as they thrust into their throats. "If you need any additional teaching aids, you can get some from this box in the front of the room"

The sadistic teacher begins demonstrating by taking a bunch on cheap office paper binders out of the box, pinching the metal wires together and releasing them around the surface area of Maria's big tits, after starting with her nipples; deftly adding one per brutalizing thrust, once they stop jiggling. He only pauses occasionally when the pain is finally too much for the abused teen, crushing her uterus with a grinding fist to stop her struggling, even though it's mostly just severe involuntary twitching, all without stopping his hammering as he empties the entire box of clips onto her breasts.

Your partner finds some clips in her backpack and adds them to your nipples, and you're destressed to barely feel pleasure from it, terrified to sober up just when it gets to the best part of class, thinking you may have already cum for the last time since Britany doesn't even lean on your face, to stop your tits from bouncing as she carefully attaches them. You're happy to be wrong about your final orgasm as she adds a clip directly to you clit, your back arching with pleasure, but unfortunately you finish sobering up halfway through, forcing you to flail in pain as the day's **** hits you all at once; until that stupid cunt starts grinding her tiny fist into your uterus to calm you down.

You finally relax, zoning out as much as possible as you begin to lose consciousness, letting yourself gently pass out like you used to do in this type of situation, before you started acting as the house urinal; barely noticing as that bitch Britney starts stuffing your lower holes with cylindrical objects from her backpack, two at a time as you continue to sleep peacefully, waiting patiently for your turn with the strap-on to get your **** on the drunken slut.
