As Aelita cautiously entered the girl's bathroom at Kadik Academy, her heart raced with apprehension. She knew she was about to confront Sissi, the girl who held embarrassing photographs of her captive. In a desperate bid to prevent their exposure to the entire school, Aelita had reluctantly agreed to this clandestine meeting, knowing that her reputation hung in the balance. With each step she took, the echoes of her footsteps seemed to reverberate the weight of her anxiety, amplifying the gravity of the situation awaiting her behind the bathroom door. As Aelita neared the bathroom stall where Sissi was supposed to be waiting, she could feel her breath quicken. She took a deep breath to calm her nerves before knocking on the stall door lightly. "Um, Sissi?" she called out, trying to keep her voice steady. The bathroom stall door creaked open, revealing Sissi's smug face. Her eyes scanned Aelita's body up and down before she spoke in a mocking tone, "Well, well, well, if it isn't little Mrs. Einstein herself. I was wondering if you were gonna show up." "Of course I did," Aelita said. "You still have those photos." "You mean these photos?" Sissi inquired almost sadistically as she held up multiple pictures of Aelita's naked butt. Aelita's face burned crimson with humiliation as she realized that Sissi had indeed brought the photos along. "I can't believe you took those while I was changing..." Aelita muttered in dismay. "Yeah, I know," Sissi said proudly. "You really shouldn't let yourself be the last one in the changing room, otherwise this could happen. And don't get any ideas, there's more where these came from. I got tons of copies hidden somewhere, somewhere you'll never find them." Aelita gasped in horror before she took a tentative step forward, trying to figure out how to salvage the situation. "Sissi, please," she pleaded, her voice barely above a whisper. Sissi smirked, enjoying the power she had over Aelita. "You know what, Aelita? I do have an idea," she said, her voice taking on a more sinister tone. "You can do something for me, and I promise not to expose you." Aelita felt a knot form in her stomach as she tried to maintain her composure. "What do you want me to do?" she asked hesitantly. "I'll do anything to keep those pictures from getting out." "Anything?" Sissi asked with a growing smirk. Aelita nodded rapidly. "Yes, anything!" "Hmm. Well then, in that case, I want you… to kiss me." Sissi declared. As Aelita's heart stopped in her chest, she couldn't believe what she had just heard. She looked at Sissi, shock and disbelief written all over her face. "You... you want me to kiss you?" she stammered. Sissi nodded, her smirk growing wider by the second. "Yes, Aelita. That's exactly what I want." She paused for dramatic effect before adding, "Or else these pictures will be all over the school tomorrow." Aelita's mind raced as she tried to process the situation. "But… But why?" she asked, both nervous and confused. "Because it's payback time, sweetheart," Sissi replied, her voice dripping with venom. "You've been such a stuck-up know-it-all. Well, now it's my turn to make you squirm." "But I'm not… I-I never…!" Aelita tried to deny it. "Shut up!" Sissi barked, making Aelita finch. Sissi then backed up into the stall. "Come in here." Aelita hesitated for a moment before stepping into the bathroom stall, her heart pounding in her chest. She felt like she was in a nightmare as she looked at Sissi, who was now standing close to her. Sissi smirked as she saw the fear in Aelita's eyes. Sissi sat down on the toilet and grinned. "Now then, squat down till you're at eye level with me, close your eyes, pucker up and lean in. Slowly." Sissi instructed. The pink-haired girl swallowed hard and did as she was told. She closed her eyes tightly, trying to brace herself for what was about to happen. As she squatted down, her face came level with Sissi's. As she started to slowly lean in, she could feel the heat radiating off Sissi's body and smelled the faint scent of her perfume. Aelita remained unaware as Sissy discreetly rose from her seat, pivoted around, and promptly discarded her skirt and dark khakis, all the while suppressing her laughter in anticipation. Bending forward, she bared her bare derrière to Aelita. "Kiss me," she commanded. Aelita nervously leaned in for what she thought would be an innocent kiss, but after she puckered up, she felt a moment of confusion when she didn't feel Sissi's lips against hers. Instead, she found herself kissing something soft and warm. With a sudden jolt, her eyes burst wide open, consumed by a mixture of shock and horror. The realization hit her like a thunderbolt, as she beheld the sight before her. A gasp escaped her trembling lips as she comprehended the unthinkable truth - she had just bestowed a wet one upon Sissy's derrière. The color drained from Aelita's face as she stared in disbelief at what she had just done. Sissy laughed and began pulling up her bottom clothes while a mortified Aelita fell backwards on her rear. "Wow Aelita, way to redefine the phrase 'kiss my butt'." Sissy mocked her before looking up. "Did you get that?" Aelita glanced upwards and let out a gasp as she noticed an individual holding a camera above the stall, pointing it downwards. She heard snickering from the next stall and turned around as the one holding the camera, Herb, and Sissi's other minion; Nicholas, came out and stood behind her. "Oh, that it was hilarious!" Nicholas said, laughing. "You thought you were kissing Sissi, but you ended up smooching her butt!" Nicholas laughed as well. "Yeah! You're a rump kisser!" Herb held up the camera to show Aelita the incriminating evidence. "Check it out!" Sissi laughed next, her voice filled with malice. "Looks like we got you red-handed! Or should I say, red-lipped?" As the realization of what had just happened sank in, Aelita felt her cheeks burning with embarrassment. She wanted to disappear, to melt into the floor. She knew she was in trouble, and the photos were only going to make things worse. Sissi's smirk widened as she stepped forward, towering over the crestfallen Aelita. "I think it's time we teach you a lesson about not crossing us, sweetheart. Boys?" Herb and Nicholas stepped forward and each grabbed one of Aelita's arms as they forced her to her feet. She struggled as they made her back up out of the stall. "Let me go!" Aelita protested. "Ok!" Nicholas said before he and Herb tossed Aelita to the floor. She groaned as she struggled to lift herself up, managing only to raise her buttocks. Before she could get the rest of her body up, the two dorky boys quickly kneeled and tied her wrists together behind her back with rope. Aelita looked up at them in disbelief as they stood up, smirking down at her. Sissi walked over to her with a mischievous glint in her eyes. "Wow, what an alluring pose! But I have an idea on how we can make the view even better." She crouched low and raised Aelita's deep pink jumper dress, revealing her lacy panties. “No!" Aelita cried out, trying to squirm away, but she was helpless. "You can't do this!" Sissi chuckled as she hooked her fingers into the waistband of Aelita's panties and slowly slid them down her legs, exposing her bare bottom. "Now that's what I'm talking about!" Sissi exclaimed sadistically pleased. After she stood up straight, she started to laugh and clap. Herb and Nicholas joined in the laughter as they high-fived each other. Aelita's face was a mixture of shock, humiliation, and fear as she stared at them with wide eyes filled with unshed tears. "But of course, it wouldn't be right to keep this tantalizing view to ourselves." Nicholas and Herb each held up a camera. "All set, sissy!" They both said. Sissi grinned maliciously and licked her lips, her eyes glinting with sadistic glee. "Excellent. Now let's have some fun!” she said. “Better smile for the camera, Aelita. Go ahead boys, take as many as you'd like. Make sure there's enough for everyone at school to enjoy Aelita felt a chill run down her spine as she realized what Sissy was planning. She tried to move, but it was no use. The cameras clicked and flashed away, capturing every moment of her humiliation. As this happened, Aelita could feel the heat of shame creeping up her neck and face. She wanted to disappear, to melt into the floor, but there was no escape. The twelve-year-old felt a stinging sensation as a tear rolled down her cheek, unable to hold back any longer. She looked up at Sissi, her eyes pleading for mercy, but all she saw was a twisted smile on the girl's face. The cameras stopped flashing when Sissi kneeled behind her again, then set one hand on her back and raised the other. "Don't do this," Aelita whispered, her voice barely audible. "You wouldn't..." Sissi's smile widened, and she nodded. "Oh, but I would, sweetheart." With that, Sissi gave Aelita's bare bottom a hard smack. The sound echoed through the bathroom, and Aelita's eyes widened in shock. She had never been spanked before, and she didn't know what to expect. As the stinging sensation spread across her bottom, she let out a soft whimper. "One whimper?" Sissi asked, sounding almost amused. "I think you can handle more than that." She raised her hand again and brought it down with a resounding crack on Aelita's already sore bottom. This time, Aelita let out a small yelp of pain. "See? Told you so." Sissi chuckled and continued spanking Aelita, alternating between sharp smacks and hard slaps that left bright red handprints on her pale skin. The pain was intense, but what hurt even more was the humiliation of being treated like this in front of two perverted boys. Aelita squirmed and wriggled, trying to escape the onslaught of slaps, but the rope around her wrists held her tightly in place. Her bottom felt like it was on fire, and she could feel the stinging heat spreading outwards. As the spanking continued, Aelita let out muffled sobs and pleas for them to stop, but it was clear that Sissi had no intention of doing so. Herb and Nicholas watched with perverse fascination, as they moved to a different spot, they used their cameras to capture every moment of Aelita's humiliation. After what felt like an eternity, Sissi finally stopped spanking Aelita's sore bottom. The room fell silent for a moment, filled only with the sound of Aelita's ragged breathing and her soft sobs. "There you go, sweetheart," Sissi said, her voice almost gentle. "All nice and red for everyone to see. Now, come on, let's get you cleaned up." She stood up and motioned for Nicholas to bring the bucket of warm water and a washcloth. Herb grabbed a towel to dry her off. Aelita remained still, too shocked and humiliated to move. As Sissi helped Aelita into a standing position, she couldn't help but notice the way her bottom felt sore and tender from the spanking. She felt like she was on fire, and every step was excruciatingly painful. Her heart was racing, and she could feel tears streaming down her face. As Sissi guided her toward the shower room, Aelita couldn't help but feel like a broken doll. She knew she had to endure whatever was coming next if she wanted to survive this ordeal. The boys followed close behind, their cameras ready to capture every moment of her humiliation. In the shower room, Sissi turned on the water and helped Aelita step into the stall. The warm water felt good against her sore bottom, but she couldn't help but feel self-conscious as Sissi began to soap her up. As Sissi lathered the washcloth and began to clean Aelita's most intimate areas, she couldn't help but feel even more humiliated. The boys stood outside the stall, their perverted giggles echoing through the small room. After what felt like an eternity, Sissi finally rinsed off the soap and helped Aelita step out of the shower. Herb handed her a towel, and she dried herself off as best she could while trying not to expose too much of her body. Once she was dry, Sissi guided Aelita to her dorm room, where they had set up a makeshift photo studio. The boys had arranged a series of revealing outfits on the bed, each one more provocative than the last. Aelita's heart sank as she saw what was in store for her. Sissi smiled wickedly at Aelita and nodded. "That's right, sweetheart. Now, let's get you dressed up for your big debut." She turned to the boys with a smirk. "Gentlemen, get your cameras ready. We have a show to put on." Aelita felt a wave of nausea wash over her as she saw the revealing outfits laid out on the bed. She knew that resisting would only make things worse for her, so she silently complied as Sissi stripped her and helped her into the first outfit. It was a tiny black bikini that barely covered her modesty. The material was thin and revealed every curve of her body. As Aelita stood there, she could feel the boys' eyes on her, taking in every inch of her exposed flesh. Sissi nodded in satisfaction at the sight of Aelita in the bikini. "Perfect," she said with a smile. "Now, let's get some pictures." She turned to the boys with a wink. "You two can start snapping away while I get her into the next outfit." As Sissi left the room, Nicholas and Herb began taking pictures of Aelita from every angle. They couldn't believe their luck; they were getting an up-close and personal view of their classmate in various states of undress. The experience was both thrilling and unsettling, but they couldn't help themselves. Aelita stood frozen, feeling exposed and vulnerable in the bikini. She tried to cover herself with her hands, but it only drew more attention to her body. She couldn't believe what was happening to her. As Sissi returned with another outfit, Aelita braced herself for the next round of humiliation. The next outfit was even more revealing than the first; it was a skimpy red lingerie set that left little to the imagination. As Sissi helped Aelita into it, she couldn't help but feel even more exposed than before. The fabric was so sheer that Aelita could almost see through it herself. Once Aelita was dressed, Sissi positioned her in front of a large mirror. "Now, let's see how you look, sweetheart," she said, her voice dripping with sarcasm. Aelita hesitantly approached the mirror, her heart racing as she got a good look at herself. She gasped at the sight of herself; she had never seen anything like it before. The red lingerie clung to her body like a second skin, accentuating every curve and contour. She looked like a porn star, and it was terrifying. As Aelita stood there, unable to move or speak, the boys continued to snap pictures from every angle. Sissi smiled wickedly as she watched the boys enjoy themselves. "Now, let's get some close-ups." Just as Sissi instructed, Nicholas and Herb moved in closer to Aelita, their cameras ready to capture every detail of her exposed body. They took pictures of her face, her chest, her stomach, and even her private areas. Aelita felt like she was in a nightmare. She wanted to scream, to run away from this horrifying ordeal, but she couldn't move. Her body felt like it wasn't her own anymore. As the boys took pictures of her most intimate parts, she could feel the heat rising in her cheeks. Sissi couldn't help but laugh at Aelita's discomfort. "That's it, sweetheart. Just relax and let us have our fun." She ran her fingers through Aelita's hair, pulling it back to reveal her neck. "You look so beautiful like this." Aelita's heart sank even further as she felt Sissi's fingers tracing along her neck. She closed her eyes tightly, trying to block out the humiliation she was feeling. As the photoshoot continued, Aelita felt like she was being violated in every way possible. She could hear the click of the cameras capturing every moment of her humiliation. The boys seemed to enjoy themselves, laughing and making crude comments as they took pictures. Finally, after what felt like an eternity, the photoshoot was over, but a new torment began. As Sissi entered the classroom with Herb, Nicholas and Aelita, they found only a handful of students remaining, and there was no sign of the teacher. Taking advantage of the situation, Sissi ordered Aelita to shed her clothes and kneel before her. Aelita, trembling with both fear, stripped naked and bowed down while humbly apologizing for tarnishing Sissi's reputation in front of their peers. As she continued to kneel before Sissi, Aelita could feel the eyes of her classmates on her body. She wanted to die of embarrassment, but there was nothing she could do. Sissi grinned smugly. "Well, well, well... It seems our little Aelita has been quite the naughty girl." She paused for dramatic effect before continuing, her voice dripping with sarcasm. "I'm sure you all know about the pictures that were taken of her in those... revealing outfits." Aelita's face flushed with shame as she heard Sissi's words. The other students murmured in confirmation while laughing and pointing at Aelita. "Now, Aelita here is going to apologize to every one of you for her behavior." As Sissi spoke, Aelita gulped loudly. She looked up at the faces of her classmates, all looking at her with disgust and amusement. As Sissi instructed, Aelita began to apologize to her classmates one by one, each word feeling like a dagger in her heart. As the apologies continued, Aelita felt like she was being torn apart. She could feel the weight of everyone's judgment pressing down on her. Finally, after what felt like an eternity, Aelita finished apologizing to everyone in the class. She was left feeling utterly humiliated and exposed. Sissi nodded with satisfaction as she watched Aelita collapse in a heap on the floor. "That's better," she said coldly. "Now, I want everybody to leave the class and don't let anyone in, not even a teacher. Aelita and I have a few last things to go over." As the students filed out of the room, Aelita could hear their laughter and whispers following her. She curled up into a ball, trying to make herself as small as possible. She felt like she was in a nightmare that she couldn't wake up from. Sissi walked over to Aelita, towering over her. "Now Aelita, I got one more thing for you to do," she declared. "After which, you will be my slave forever. Got it?" "Y-Yes..." Aelita whimpered in response, not daring to look up at Sissi. "Speak up and look me in the when I'm talking to you!" Sissi barked. Aelita forced herself to look up at Sissi, her eyes filled with fear and resignation. "Yes, Sissi. I understand. I will be your slave forever." Sissi smirked, pleased with Aelita's submission. "Good girl," she purred, running her hand through Aelita's hair once more. She walked over to the teacher's desk, removed her skirt, khakis and underwear again and bared her tushie for Aelita once again. "Now then slave... kiss my butt." Aelita hesitated for a moment before standing up, walking closer then lowering her head and tentatively kissing Sissi's butt. She felt the cold hard cheeks beneath her lips as she pressed them against Sissi's flesh. Sissi let out a small laugh. "Good girl," she said, "But you're gonna need to show more enthusiasm." "Yes, mistress..." Aelita said almost robotically. Sissi wiggled her bare butt at Aelita. "Alright then, slave. Keep kissing. Worship my heinie." Aelita swallowed hard and leaned in again, kissing the smooth flesh of Sissi's butt cheeks once more. As she pressed her lips against Sissi's cold skin, her tongue darted out to taste it. Sissi felt Aelita's tongue on her butt and let out a small moan of pleasure. She smirked as she continued to wiggle her ass in front of Aelita, encouraging her to lick and kiss it more. "That's it, slave. Show me how much you want to please me." Aelita felt a strange mix of shame and arousal as she obeyed Sissi's commands. Her tongue darted out again, tracing the crease between Sissi's butt cheeks. She could feel her heart racing as she licked and kissed the soft flesh, trying to please her mistress. After a few minutes of worshiping Sissi's butt, Aelita felt a warm sensation between her lips. She pulled back and looked up at Sissi, who was now glancing at her a wide grin. "Perfect, slave. You have pleased me well." As Sissi spoke, Aelita gulped loudly. She looked up at her mistress, her heart racing with both fear and arousal. "Thank you, mistress," she whispered, her voice shaking slightly. Sissi chuckled softly. "Don't thank me yet, slave. You kissed my butt, now kiss my butthole.” Aelita hesitated for a moment before stepping forward and kissing Sissi's butthole. As she pressed her lips against Sissi's tight hole, she could feel the heat emanating from it. She gently licked around the entrance, tasting the sweetness mixed with the tang of arousal. Sissi let out a soft moan, encouraging Aelita to continue. Aelita tentatively probed her tongue deeper into Sissi's anus, circling it gently as she tried to explore every inch of her mistress's backdoor. "Ahh... that feels good," Sissi moaned softly, her hips beginning to buck slightly. She closed her eyes and let out a long, slow breath as Aelita's tongue continued to explore her tight anal entrance. After a few minutes of stimulation, Sissi's breathing became heavier, and she let out a soft whimper. "Enough for now, slave," she panted. "But don't forget, you'll be serving me like this from now on." Aelita pulled her tongue away from Sissi's anus, feeling a mixture of relief and arousal as she did so. She looked up at Sissi, who was now standing up straight and facing her again, her face flushed with pleasure. "Yes, mistress," she whispered. "I understand." Sissi smirked at Aelita's submission. "Good girl," she purred. With that, she gathered her things and walked out of the classroom, leaving Aelita alone to ponder their new arrangement. As she walked away, Aelita couldn't help but feel a strange mix of shame and excitement about her newfound role as Sissi's personal butt slave
