Scene: A typical classroom, except there are simply chairs in place of student desks. Most of the chairs are occupied by teenage girls, a majority of them wearing the school uniform of pink panties, a burgundy pleated microskirt, and a white blazer-like blouse. All the girls in the room are staring ahead at the professor's desk with expressions of awe or dread, and most of their seats seem to be wet. Prominent are three girls sitting in the front row before the professor's desk. The first girl wears red high-heeled shoes, white thighhigh socks, the school uniform, and earrings decorated with small rubies. Her hair is additionally tied into two pigtails. The second girl wears black kneehigh high-heeled boots, low-rise jeans (with holes ripped in several spots, including the crotch to reveal light blue panties), a blue cropped tube top with "BITCH" printed in white on it, and a black choker. She is additionally wearing dark blue eye shadow and lipstick. The third girl wears pink sandals, the school uniform (the blouse unbuttoned at the bottom and tied in the back, revealing her golden navel piercing), a pearl necklace, and golden hoop earrings. More prominent is a nude man sitting in the chair behind the desk and the woman on top of him. The woman wears dark red high-heeled shoes, black fishnet tights (with a large hole torn in the crotch), a black tight microskirt with slits on both sides, a dark red blazer (buttoned only in the middle), a white low-cut tube top under the blazer, and glasses. She is wearing heavy make-up, including dark violet eye shadow and bright red lipstick. The woman is supporting her legs by standing them on the desk while her arms are held by the man, whose large penis is partially in the woman's vagina and making her stomach bulge slightly. Another girl, a slightly-plump young adult, stands near the desk and is also watching the scene. She wears black boots, black thighhigh socks, a black translucent babydoll, black elbow gloves, and a black collar with "LOVE" engraved on it. Understandably, none of the students had spoken during the professor's lecture. "So, on the test," Professor Tetramora was saying, sliding up and down on the Master's giant cock, "you'll have to oh yes... to move up and down like this until the Master gives you c-ahh... cum in your pussy. If you pass out during the test, you'll either fail mmm so good... you'll either fail or get partial credit. I'll... be collaborating with the Master to get his o-oh Master... his opinion. If you do pass out, though, you probably won't get the f-fuck fuck fuck... you probably won't get the full grade, so it'll help if you stay conscious. Now, if... if you haven't in a while, you may want to get unh, this wonderful cock up your cunt...! So that you'll be more used... used to it. Also, if the Master has already used your pussy recently, you ah ah are eligible for a waiver on the test, provided he was satisfied by y-you oh Master, yes!" Cheri stared, open-mouthed and slightly drooling, as Professor Tetramora started to moan incoherently. The Master shoved her onto her desk and thrust his cock a little more into her, and it was soon clear that he was dumping a huge load of cum into the professor. Professor Tetramora's eyes had rolled up, her tongue hung out, and her arms hung limp over the desk as the Master gave her his cum. It had seemed so sudden, this occurrence. Previous classes in Sex Education had mostly involved theory or girl sex, but then today the professor announced a special guest. Nobody had expected the Master and his Wife to enter the room, nor had they expected the Master to immediately pick up Professor Tetramora and thrust his cock through her fishnet tights and into her cunt. It was at that point that Cheri had felt her seat and panties get wet. After some time, the Master pulled his cock out the bloated professor, wiping the cock with her skirt. His Wife immediately ran over and licked the remaining cum off the Master's cock, smiling up at him and stroking it afterward. "The test is in a week," Professor Tetramora sighed, closing her eyes contentedly. "Thank you for coming, Master. I hope you'll have no trouble returning next week." "He's very fond of children," the Master's Wife said, still rubbing the Master's cock. "And a good education makes more useful sex objects." The Master and his Wife left, then, and Professor Tetramora dismissed the class with a wave. Some girls got up to leave, while others stayed in their seats and rubbed their pussies. Cheri ignored her dripping panties and stood up. "You coming, Cheri?" Patti asked with a smirk, standing up from the chair next to Cheri. Patti's panties and the butt of her jeans appeared to be soaked. "If we hurry, maybe we can get used by the Master and his Wife," Chaya whispered, approaching them while rubbing her wet panties. "It's lunchtime anyway." "You two go ahead," Cheri said, still looking at the limp professor. "I wanted to ask the professor something." "He's probably too busy anyway," Patti sighed. But she and Chaya left anyway. Cheri approached Professor Tetramora nervously. "Cheri," Professor Tetramora murmured, opening her eyes. "Come closer. Is... something wrong?" "N-no professor," Cheri said, obeying. "I just wanted to... ask about the test." "Are you... hungry?" the professor asked, lifting herself up and sitting on the desk. Cheri was amazed to see that, though the professor's skirt and pussy were covered with cum, the enormous amount still inside her was only barely leaking out. "Professor!" Cheri exclaimed, staring. "H-how...?" "Open," the professor ordered, grabbing Cheri's head and pulling it closer. Cheri found her mouth up against Professor Tetramora's cum-covered cunt. As she opened her mouth, cum suddenly began to gush out of the professor's cunt and into Cheri's mouth. Professor Tetramora gasped and moaned, wrapping her legs around Cheri's neck before taking her hands off Cheri's head. "Mmm... that's good, Cheri," the professor told her, gently rubbing Cheri's head. "I used to work as a cumdump, and you can guess how this was a skill in high demand." Cheri couldn't respond. She swallowed the cum that filled her mouth as more rushed in to replace it, and already found herself getting full. Professor Tetramora kept her legs around her, though, so she kept drinking the cum until the flow died down to a trickle, which was when the professor released her. The professor then leaned forward, showing off her magnificent tits bulging from under her shirts, and kissed Cheri hard. Cheri felt the professor's questing tongue and gave her some of the cum still in her mouth. After a while, the professor broke the kiss and sat back on her desk. She was no longer bloated with cum, though Cheri felt a little bloated now. "Now then," she said, licking her lips, "what was it you wanted to ask about?" "About the test next week," Cheri mumbled. "I... I'm not sure if I can do it." "Oh?" the professor asked, raising her eyebrows. "I've never..." Cheri whispered. "I mean, I'm a virgin." "Ah," the professor said, understanding. She leaned back at looked at the ceiling thoughtfully. As she did so, her legs wrapped around Cheri again and pulled her to her pussy. Cheri responded by suckling the professor's clit. "Mmm," the professor moaned. "So... I think your best chance is to go to the Master's house and make as many appointments as you can. Unless you plan on seeing how you do as you are on the test, but... usually girls don't last too long the first time." Cheri lifted her head to talk. "But, can't I just... do something else instead?" The professor glanced down at Cheri, who went back to sucking. "Cheri, you're not a lesbian are you?" "No!" Cheri exclaimed into the professor's cunt, briefly lifting her head again. "No, I just... I don't feel like I'm ready." "I'm honestly a little concerned about you," the professor said, patting Cheri's head. "But, you should be ready. Playthings a lot younger than you are ready. Besides, this isn't the only test in Sex Education which involves the Master." Cheri didn't respond, and eventually Professor Tetramora shuddered and dismissed her. Lunchtime was already almost over, so Cheri walked straight to her next class. Along the way, she saw a few cum-filled girls lying on the hallway floor. In Homecare, Cheri found Patti and Chaya already at their seats. "Hey homeslut," Patti greeted her. "We didn't see you during lunch. The Master used a few whores, but unfortunately not us." "We got to get some fresh cum from them though," Chaya chimed in. "It's way better." "Yeah," Patti agreed. "So where were you?" "I was... talking to Professor Tetramora," Cheri said. "About the test." "Ahh you cleaned her, didn't you?" Patti asked. "I was wondering why you looked filled up." "And all to yourself, too," Chaya murmured. "We had to share our cum." "I... I could still give you some," Cheri suggested, feeling her stomach. "Nah it's okay," Chaya said. "Yeah we had our fill," Patti agreed. "Enjoy your luck." The professor came in, then, and instruction began. The topic of the past few days, including this one, was how to clean cum-covered clothes by sucking on them. By now Cheri more or less had the technique down, so she found herself thinking about other things, especially the upcoming test in Sex Education. After school, Cheri told her friends that she was going to her mom's house to get something. However, she instead made her way to the Master's house. As was polite, Cheri rubbed cunts with the girl who greeted her at the door. Cheri asked the girl where she could make appointments, and the girl pointed her to a room. In the foyer, Cheri saw a lot of random puddles of cum and girls drinking from them. When Cheri entered the room she had been directed to, she found to her disappointment that there was a long line in front of a desk. Cheri sighed, knowing that she'd never get to the desk before bedtime, and resolved to try again a different day. It was with growing dread that Cheri passed the next six days in a similar fashion, at no time being able to schedule an appointment, and found herself sitting in Professor Tetramora's class on the test day, utterly unprepared. "Well, this is the big day," Patti said. "I didn't have a chance to go the Master's house," Chaya muttered. "It's not fair to throw this test at us with all the other classes going on." "Yeah," Patti sighed. "I didn't get a chance either. What about you, Cheri?" Cheri merely shook her head. The Master and his Wife entered the room. The professor got up from her seat and offered it to the Master. The Master shoved the professor's mouth onto his cock, but only once before he took the seat. The professor rubbed her throat for a moment before moving to stand next to the Master's Wife. "We'll begin testing now," Professor Tetramora said. "There're thirty of you, so you'll want to please the Master as quick as possible so that all of you get your turn. Let's see, starting with... Patti." "Fuuuck," Patti declared, rising from her seat. "Patti, for your pleasure, Master," the professor said as Patti stepped forward. Patti was wearing the same pants as last week, but she had changed her shirt to a denim cardigan, left unbuttoned. She climbed onto the desk and started to slowly unzip the zipper of her pants. "Mm," the Master's Wife said, "a good cocksleeve if I ever saw one." The Master interrupted Patti by picking her up and jamming her onto his still-wet cock, ripping through her panties and making an even bigger hole in her pants. Patti made a surprised gasp as the cock went into her cunt. Then the Master took Patti's arms and sat back. It took Patti a moment to realize what she was supposed to do, and she started to move up on the cock. Then she moved back down and winced, letting out a brief cry of pain. She stopped moving to breathe for a moment. "Time's up," the Master's Wife said. The Master then took Patti by the waist and began to fuck her hard. The cock bulging in her stomach moved up to her chest before the Master pulled her back up, only to force her down again. Patti made weak gasping sounds before she closed her eyes and became quiet. Before long her belly started swelling. The Master then set her on the floor next to the desk. Patti seemed to be unconscious, and cum was gushing out of her cunt. Professor Tetramora sighed and called on someone else as she dragged Patti away from the desk. The next girl seemed to have it more together. She had lowered her panties as she approached the Master, got on the desk, and held her arms out behind her. When the Master took them, she sat down on his cock and eased herself lower. She had a determined look, and she barely flinched as the cock went up her insides. After that, she moved up and down on the cock, breathing heavily. The Master never forced himself into her, and eventually her belly was filled with cum. The Master pat her on the head as she crawled off his cock, and Professor Tetramora nodded at her with satisfaction. After that girl, it seemed like the rest were not as skilled, though nobody had done as badly as Patti. Even so, the other girls all managed to satisfy the Master. Then came Chaya's turn. She and Cheri were the only ones who hadn't gone. Chaya had been rubbing her panties furiously the entire time. It occurred to Cheri that Chaya was probably trying to get her pussy as wet as possible. Chaya got onto the desk and dropped her dripping panties on it, then gave her arms to the Master. Slowly, Chaya eased herself onto the Master's cock and immediately began moaning. Then she pushed herself further down and started screaming in pain. The Master released an arm and picked up Chaya's panties on the desk to shove them into her mouth, reducing her screaming to muffled cries. Chaya squirmed and seemed to be trying to get off the cock. The Master then grabbed her waist and started fucking her like he did Patti. Chaya continued to scream into her panties, her eyes wide and leaking tears, until she suddenly became quiet. Then the cum gushed into her belly like the rest of the girls, and the Master set her on the floor. "Pity," the Master's Wife commented. "All right," Professor Tetramora said. "You're the last one, Cheri." Cheri took a deep breath and approached the desk. She crawled onto the desk, dropped her panties, and gave her arms to the Master. "Please, Master..." Cheri whispered as she sat on the tip of the cock. "I've never done this before, and... I'd really appreciate it if you went easy on me." Then she suddenly felt the Master kiss the back of her head. It was so unexpected she gasped and blushed. The Master let go of one of her arms and started rubbing her stomach, and Cheri felt her tenseness fade away. Then the Master reached over and picked up Cheri's panties. Cheri looked at the panties still dripping with her pussy juice in confusion as the Master gently nudged them into her mouth. As she tasted her own cunt on the fabric, she wondered why the Master put them in her mouth like he had with Chaya. Then she felt something tear her cunt open. The sound of her muffled shriek was interrupted by darkness. When Cheri regained consciousness, she was immediately aware of the worst pain she had ever felt in her life and continued screaming. The Master was holding her by the waist, shoving his giant cock into her again and again. With every thrust, her belly bulged out and she felt her mind go a little more blank. Then she felt the cock twitch inside her, and she was quickly filled up with hot cum. Cheri had stopped screaming, as she was barely even conscious. She was aware of the cum gushing into her for what seemed like an eternity before she was set down on the floor. "I suppose that leaves Cheri, Chaya, and Patti to be graded," Professor Tetramora murmured above her. "Master, what do you think?" "Let's bring the other two over here," the Master's Wife told her. Cheri felt someone dropped next to her, then someone else dropped on her other side. Then strong hands suddenly lifted Cheri's upper body. It was the Master, scrutinizing her for some reason. The Master's Wife came over and took Cheri's panties out of her mouth, casually licking them once. The Master placed Cheri in front of his cock, and Cheri saw for the first time her blood on it. She weakly opened her mouth to lick it. The Master's Wife kissed Cheri on the cheek. "You're a good fucktoy, aren't you?" Then the Master grabbed Cheri's head and shoved his cock into her mouth. "Master, wait!" Professor Tetramora protested, stepping forward. "They haven't had a lesson on deepthroating yet!" Ignoring her, the Master pushed his cock deep into Cheri's throat, reaching her stomach. Cheri felt faint again. "Don't worry about it," the Master's Wife said, rubbing Cheri's throat. "He's taking good care of her." "Master, please," the professor went on. "She might... oh." The Master took his cock out of Cheri and his Wife hugged her affectionately from behind. The Master turned to Professor Tetramora. "Thank you, Master," the professor said. "I'm just... concerned about my students someti-" The Master grabbed the professor by the hair and thrust his cock down her throat instead. She made a gagging noise and moved her arms futilely. The Master's Wife stood Cheri up and held her so that she watched this. Then Cheri felt her panties being rubbed against her cum-filled cunt, and glanced down to see the Master's Wife's gloved hand rubbing with them. The Master continued to fuck Professor Tetramora's throat as she put up less resistance and finally went limp. Cheri was astonished when the Master pushed his cock deep into the professor, so much that the cock came out the other side and pushed against her fishnet tights. The Master's Wife, who was now breathing hard, took one of Cheri's hands. Cheri felt her hand press against the Master's Wife's wet cunt, with the soft fabric of the babydoll tickling her wrist. "Rub my cunt, fuckhole," the Master's Wife hissed. Overcoming her exhaustion, Cheri pushed a couple fingers into the Master's Wife's pussy and started rubbing. "Mmm," the Master's Wife sighed, shoving the panties into Cheri's pussy and damming the cumflow. Then Cheri felt the gloved hand gently squeezing her clit. The Master had pushed Professor Tetramora all the way down his cock, such that it tore through her fishnet tights on the other side like last week. He was holding her by the waist and now seemed to just be using her to masturbate. "She needed to be reminded of what she is," the Master's Wife breathed, massaging Cheri's clit and occasionally checking to make sure the panties were still in Cheri's pussy. "She's a fucktoy just like the rest of you. An object to be used by my Love. Remember, objects do not question their Master." The Master was furiously shoving the professor up and down his cock now. He then pulled her off enough that the cock was only her stomach and came. Professor Tetramora seemed to inflate even more than she did last week. As the Master filled her, he slowly pulled her off his cock until just the tip of it was in her mouth. He held her there for a while. The Master's Wife moaned and pushed her fingers into Cheri's cunt and panties. Cheri felt the Master's Wife shudder against her and she found herself orgasming as well. As she did, the Master's Wife pulled the cum-drenched panties out of Cheri's cunt and raised it before her. Then she stuffed it back in Cheri's mouth. "Clean it, sweetie," the Master's Wife whispered. Cheri started sucking the panties in her mouth, tasting a mixture of her own pussy juice and the Master's cum. "When you're done, I want you to put them on properly," the Master's Wife told her. "They look so cute on you." Obediently, Cheri sucked the last bits of cum out of her panties and weakly raised an arm to take them out of her mouth. The Master's Wife supported Cheri as she put one leg through the saliva-soaked panties, then the other leg. Cheri pulled the panties up to her cunt and felt it instantly become heavy with the cum still leaking out of her. "That's a good fuckhole," the Master's Wife said, kissing Cheri's cheek. The Master was done with the professor now. He placed her atop the pile of girls who had passed the test, and her open mouth let loose the torrent of cum onto some of them. The Master's Wife walked Cheri before the Master's cock and pushed her down to her knees. Automatically, Cheri opened her mouth as the cock pushed against it, and the Master shoved it in. "Oh, honey," the Master's Wife moaned as the Master's cock went past Cheri's throat. "I want a better view." The Master picked up his Wife and set her dripping cunt onto the base of his cock, so that she faced Cheri. His Wife placed her hands on the sides of his cock to keep her balance. The Master then reached over and took Cheri's pigtails in his hands, then pulled her closer so that the cock went down into Cheri's stomach. Dimly, Cheri saw the Master's Wife's wet cunt grinding against the giant cock going down her throat. The pussy juice was trickling down the cock and into Cheri's outstretched mouth. It was the last thing she tasted before fainting. Awake again, Cheri's throat was still being rammed into by the Master's cock. She noticed that the hands gripping her pigtails were no longer the strong hands of the Master, which were now massaging his Wife's tits, but rather the soft gloved hands of the Master's Wife, whose cunt was now directly in front of Cheri's face. She wondered how far the cock had gone into her, or if it even was out her pussy. It was hard for her to tell, as all she felt was a universal ache. Then the Master's Wife suddenly let go of her hair, and Cheri felt herself sliding off the enormous cock and onto the floor. The Master's Wife leaned down onto the Master''s cock so that she encircled it with her arms and legs, then inched forward to the tip. She lowered her mouth to it and suckled. A blast of cum caught her face and she sat up, letting the cum spurt onto Cheri and her two friends. Cheri was soon blinded by the cum, though she made no effort to wipe it from her eyes and simply rested. "All right you cumpets," she heard the Master's Wife say, after the river of cum seemed to dwindle. "You get extra credit if you clean off your three failing classmates here." After a moment, Cheri felt hands and mouths on her as she was slowly cleaned of cum. Even her cunt was emptied as someone sucked the cum out. When they were done, Cheri saw her classmates go back to the corner of the room they were in with the professor, leaving her alone with her friends again. The Master's Wife rubbed the Master's cock while aiming it at the classmates and unconscious professor, then a stream of golden liquid came out and covered them. After that, the Master's Wife suckled the tip clean and walked over to Cheri. Cheri felt herself being lifted up, and she saw the Master picking up Patti and Chaya. Patti he shoved onto his cock, while he placed Chaya onto the base of it where his Wife had been. Patti only made a grunting sound as the cock stretched her pussy and stomach out. Then Cheri was thrown over the Master's Wife's shoulder and she and her friends were carried away, out of the classroom and out of the school to the Master's house.
