Lightning round (Good)

"Alright, holes! Everyone without a grade lay on your desk, on your back, with your head hanging over the edge! Quick! Quick!" You command, stretching out you hamstrings like a sprinter about to start a marathon, preparing to speedrun skullfuck fifteen schoolgirl throats in less than a minute each. Maddison, ever the suck up, is the first in correct position, even though she's only doing it for extra credit. You admire her magnificent chest defying gravity while waiting for the rest of the holes to follow her lead and you have to remind yourself you're saving her for last.

You begin at the opposite corner of the room from Maddie, starting with a gorgeous tanned brunette that you might have picked earlier if you had seen her up close, though she is wearing a lot of makeup. You note the deep red streaks of lipstick being left on your long shaft as you sink down to the root in the pretty teen's virgin throat, your balls coming to rest on either side of her cute upturned nose. You hold yourself hilted for a moment, trying to grade the quality of retching and squirming esophagus wrapped around your pole. Tight, but with easy entry that allows for a satisfying pound of the full length, which you quickly use to dredge saliva out of the heavily made up hole and smash it into her face while you untie her uniform top and inspect the tan lines on her cute B-cups.

In less than a minute she's gone from enchanting beauty to gagged out whore. You're almost proud of how quickly you destroyed her as you fire a quick few pumps of jizz into gullet then pull out to fill her upturned nostrils and glue her long eyelashes together. You almost give her an A, but she coughs up most of the cum you shot in her mouth, letting it roll down her face and into her hair, so you write a B on her neck for being a bad swallower and clean her lipstick off your cock on her white uniform top. You're making good time!

The next desk has a stacked blonde with an adorable face and an extremely small body, who might be shorter than Heather, but with gigantic breasts that look ludicrous on her tiny frame. She smiles at you nervously as you approach, revealing two cute dimples for you to grind the tip of your cock into as she opens her mouth for you. You immediately try to slide into her throat, getting less than halfway before running into **** resistance at the entrance of her throat; her lips spread to nearly their limit just pushing the head inside. You spend nearly her entire minute slamming the back of her head into the edge of her desk, untying her uniform top and using her huge tits for leverage by yanking her puffy pink nipples towards you.

Just as you are about to give up and fail her, you give one final slam, knocking the tiny teenager **** and allowing your thick girth to pop into her tight neck while you elongate her huge tits well over her head. You quickly begin filling her stomach with a sizeable load, pleasantly surprised with how nice it is now that you're inside. You decide to give her a B since most of your cum stays in her belly where it belongs. You quickly slap her giant rack on both sides to leave your handprints on the passed out teen's glowing white orbs before moving quickly on to the next hole.

You hilt yourself easily into the throat of a chubby goth chick with black hair, finding her esophagus too loose, especially after you just finished with the tiny blonde. You grab her neck and squeeze her double chin tightly to give yourself additional traction, but still find her sub-par, so you pound into her face extra hard to make up for it, before quickly feeding her your jizz. You give her a C anyway, for greedily gulping your cum like a hungry animal, at the very least, then move on to the next worthless hole.

Beginning to hit your stride, you quickly move through a light skinned black girl, a dark skinned black girl, another blonde, another brunette, two more Asians... holes of all sizes and colors rapidly blur together as you throatfuck your way up and down the 5x5 grid of desks filling every ungraded stomach with a copious contribution of your seed then rating them like a piece of meat.

You finally reach Maddison, surprised to have 3 minutes to spare before the end of school. You untie her top and play with her perfect chest while taking your time to truly enjoy the overachiever's velvet throat working up and down your shaft trying to convince you she gives the best head in class. Maddie earns her A++ so quickly that you're surprised to have a full minute to spare.

"I just need any hole to get a passing grade, right?" Michelle asks, bending over and pulling one taunt cheek to the side, to let you choose if you want to grade her pussy or her ass. She doesn't want to be the only hole in class to get detention. You sigh.

Michelle's asshole is a solid B, you decide, writing the grade on her rear and pouring your spunk inside her tight rear just as the bell rings to end the day.

You can't believe it. The whole class passed the oral exam. Maybe there's hope for these holes yet.
