Forcemasc in Wonderland

Summary:

Alice had thought she was smart.
The rules had been clear: Night Raven College was an all boy’s school. She’d thought that was stupid. After years of wanting to go to her brother’s school, hearing stories of what it was like, she wasn’t even allowed to go? No way! She’d show all those stupid boys what a real mage could do. She put on her brother's uniform, called herself Ace, and got into NRC, no problem.

Then Alice is caught, and expects to be expelled. To her shock, however, Riddle decrees that he will make her a proper Heartslabyul student in accordance with the queen's rules.

And all Heartslabyul students are boys.

Notes:

I'm back at it with the forcemasc, this time in a new fandom. I decided to take advantage of Heartslabyul's weird rules for sexual purposes.

In this fic, Ace refers to himself with feminine pronouns and a woman's name (Alice) for much of this. if you don't like that, then this is not the story for you. He figures himself out later (under duress of course) but it takes a while. There's also some discussion of his chest, and he refers to his body in feminine terms until he doesn't.

Unless otherwise specified, assume that all character are of age. I know he's sixteen in the game he's not here

Chapter Text

Alice had thought she was smart. 

The rules had been clear: Night Raven College was an all boy’s school. She’d thought that was stupid. After years of wanting to go to her brother’s school, hearing stories of what it was like, she wasn’t even allowed to go? No way! She’d show all those stupid boys what a real mage could do. 

So she’d stolen her brother’s clothes, cut her hair, and called herself a new name: Ace. She’d worried the Dark Mirror would catch her lie, but nope! She’d been sorted into Heartslabyul without anyone suspecting a thing. 

That swiftly fell apart barely a day into starting classes, however. It turned out, pretending to be a boy was hard. She’d been sloppy, fallen asleep without the chest binder she’d made (to be fair, she’d read online that it was dangerous to sleep in one, but here she was) and her roommate, Deuce, had seen. 

“Bro,” he said, looking deeply confused. “You have boobs?” 

Alice didn’t know what to do. She squeaked (fuck, her voice was too high) “Don’t look!” 

She’d thought she was smart. But, Alice realized, she might have been very stupid. 

 

…..

 

The Heartslabyul courtroom was quiet as Alice knelt trembling, the heavy collar around her neck. Everyone was quiet. 

“The rules are clear.” Housewarden Riddle Roseheart’s voice rang out. “Night Raven College is a men’s only school. Furthermore, Queen of Hearts rule 47 states that no woman must ever enter the dorm.” 

That was a rule? Seemed overly sexist, Alice thought. In fact, all of this felt that way. Whatever. Her game was over. She’d be expelled. That would be the end of it. Already she’d been chafing against the rules in this insane dorm, anyway. What kind of dorm had such strict rules about what kind of tea you could drink? 

She looked up at Riddle. The small figure in the box looked incandescent with rage, blue eyes flashing, a scepter clutched in his hand. 

“Look,” Alice piped up. “I’m sorry. This was all a huge mistake. Take me to the headmage, I’ll accept any punishment.” 

“I’m afraid this is a dorm matter,” Riddle replied, voice sharp. That didn’t make any damn sense. “After all, the Dark Mirror chose to place you here.” 

“But I’m a girl,” Alice protested. “I don’t belong here.” 

“Not according to the mirror,” Riddle said. “I invoke rule number 70: In the event that a woman does enter the dorm, she will be altered.” 

“Altered?” Alice asked in a small voice. What did that mean? She touched the collar gingerly. Surely they weren’t going to chop off her head for real. 

“Ace Trapola, you are hereby sentenced to become a proper Heartslabyul student,” Riddle called out, pointing his scepter down at her. Why was he using her fake name? He knew her real one already. “Henceforth, you are a man.” 

Wait. 

What?

……

 

“You know I hate coming to you,” Riddle sighed as he sat gingerly on the couch in Azul’s private study. “There’s simply no other way to rectify this issue.” 

Azul had listened to Riddle’s story with great interest. He could already feel the ways he might be able to hold this over the other housewarden’s head. 

“Don’t you think it might be against the rules to allow the little girl to remain here?” He asked, amused. Riddle glared at him. 

“Ace is not a girl,” he said. “Thus, it’s not against the rules.” 

“Even getting the potion from me? That’s okay, too?” 

“I am buying a completely legitimate alchemical formula,” Riddle said stiffly. “Ace must be made to conform. As it is now, his body is unacceptable.” 

“Makes sense. Why don’t you just share your own?” Azul grinned. Riddle being trans wasn’t exactly a secret, but he liked to remind him about it. He was sensitive. 

“I need it,” Riddle said. “Additionally, it would be against the rules to share one’s medications. Ace’s potion needs to be extra strong, as well. I started transition younger than he will. We don’t have time to waste.” 

Azul nodded. He saw no reason to deny Riddle’s request. “I’ll have it ready for you in a few days,” he said. “Please keep me informed on how it’s going, too. I’ve heard this formula is quite effective. I would love to see the results.” 

“Very well,” Riddle said. “How much do I owe you?” 

Outside the office, Riddle heaved a heavy sigh, and called Trey. 

“I’ve spoken with Azul. He’ll have the medication for us.” 

“All right. I hope it wasn’t too much trouble.” 

“It was the same as usual. How is he?” 

“Well, he isn’t taking things very well. Riddle, are you sure you want to do this? It seems…I don’t know, extreme.” 

“Are you questioning the rules, Trey?” 

“Sorry, Riddle.” 

“I’ll be right over.” 

…….

 

Alice had been confined in this room for too long, still collared to seal her magic away. It was the weekend, so she hadn’t had to attend classes, although Riddle had made it clear that on Monday she was to return to class, as Ace. 

It was fucking mental. These freaks had locked her up, and refused to use her real name no matter how much she corrected them. She wanted this to end, she wanted to go home. It was all a big mistake. Why wouldn’t they have her expelled already? 

“Hello, Ace.” Riddle entered the room, followed by the junior, Trey, and a few other boys. 

“That’s not my name.” Alice remained defiant. She would just have to resist this little tyrant as long as possible. 

Riddle clenched his teeth, obviously furious. “Insolent boy. Why do you persist in this disobedience?” 

Alice looked at the other boys imploringly. “Hey, don’t you think this is crazy? I’m not a boy. Look at me!” She gestured to her chest. Alice was fairly well endowed, although not difficult to hide with a chest binder until now. They’d given the binder back to her, but she had decided to leave it off. 

“Do you have such pedestrian views on gender?” Riddle walked up to her with a clicking of his heels. “Do you really think one’s outward body determines whether or not someone is a boy or a girl?” 

“Well…yeah?” Alice blinked. “Boys don’t have boobs, and girls don’t have dicks. It’s stupid to keep calling me a boy when I look like this.” 

Riddle’s face was red. Alice sensed she’d probably said something wrong. 

The housewarden flicked his scepter, and vines began to encircle Alice, gripping her arms and legs and pulling her off her feet into a spread-eagle position. Sharp thorns tore at her clothes, baring her body. She shrieked, trying desperately to avoid being exposed to the boys. She’d never been naked in front of a man before. Her cheeks burned with humiliation. 

“You fucking pervert! How dare you – “ 

A muttered spell from Riddle sealed her lips shut. 

“Riddle, isn’t this a little…” Trey looked uneasy. Fucking finally, someone was having a second thoughts. 

“That’s enough, Trey. This is his punishment. And besides,” Riddle pulled a vial from his pocket. “I need to administer this. It must be applied on bare skin.” 

“But, she’s I mean he’s naked,” Trey said. Some of the other boys looked uncertain as well. 

“Weak fools, the lot of you,” Riddle snapped. He walked right up to Alice and cupped her chin in his hand. “You poor thing,” he murmured. “One day you’ll thank me.” He removed a glove and poured some of the vial’s contents on his hand. Alice shook her head, terrified. Whatever that stuff was, it couldn’t be good. 

Riddle rubbed the liquid onto Alice’s skin surprisingly gently, over her stomach and shoulders. It dried quickly, the feeling tingly. 

“I asked Azul for something strong,” Riddle murmured. “I’ll be reapplying this every week, but you’ll start to see changes very quickly. 

What the fuck was he talking about? Alice wriggled in her bonds. If only this collar wasn’t around her neck. If only she could clock Riddle right in his pretty face. Stripping a girl naked like that, touching her…this was assault. This was disgusting. 

“I know you don’t understand why I’m doing this, “ Riddle said, “But what you think does not matter. The Queen’s rules are absolute. From now on, you will not call yourself Alice. If I hear that name cross your lips, it will be off with your head. If you speak of this to any of the other students, or the headmage, you will be confined here again until you submit. You will not betray this dorm. 

Alice trembled, still furious. However, she was beginning to understand that submission, for now, might be the right call. She’d bide her time, figure out an escape. Later. 

Riddle removed the spell on her lips. “Tell me you understand.” 

“I understand.” 

“What is your name?” 

“Ace Trappola, Housewarden.” 

“Very good.” The vines pulled away, and Alice curled up, trying to hide her body. Riddle stared down at her. “New clothes and underthings have been delivered to your room. You will wear them.” 

“Yes, housewarden.” Alice burned with humiliation. This little fucking freak. She’d show him. She’d play nice for now, but later…

…….

 

It turned out not to be too difficult to call herself Ace. She’d chosen the name, after all, and it had been her nickname once, when she was a little tomboy wearing her older brother’s clothes. It wasn’t a bad name. 

Everything else, though, was a massive adjustment. Riddle had ordered several dorm members to keep a close watch on her, so she never had a chance to speak up and rat them all out to the other students. It seemed like the members of Heartslabyul were really intimidated by Riddle. Sure, he had strong magic, but he was just a little brat, really. Ace wished they’d all grow a spine. 

Being in a dorm full of boys who knew her secret was terrifying in itself. One night, she was getting ready for bed when she spotted Deuce staring at her. 

“What are you looking at?” She snarled. 

“Nothing,” Deuce said, glancing away. “Um, you look different?” 

Ace glared at him. “I’m the same as ever,” she replied. 

“You face is less round,” Deuce said, “And you kinda have, I don’t know, more hair on your body?” 

“Don’t be a fucking creep,” Ace told him. “It’s rude to comment on a girl’s hair.” 

“You’re not a girl, though,” Deuce said. “I mean, not anymore, right?” 

Ace stomped out of the room with her shower supplies, extremely put out. Nothing about her had changed! She was a normal girl! She was just a little hairier because that little tyrant had forbidden her from shaving. 

It was good the bathrooms had shower cubicles, she mused, slipping into one and closing the curtain firmly. Still, she tried not to be here when there were a lot of boys around. She shucked off her sweatpants and shirt, and was forced to reckon with an uncomfortable fact. 

She really was changing. Her stomach and legs were growing hairier, the red strands stringy in the hot water. Her voice had gotten deeper, which she noticed when she snapped at Deuce. 

Then there was her clit. 

She’d tried to avoid thinking about it for a few weeks now. Something about that potion was making it grow, and now it was at least and inch. It shouldn’t be possible for it to change that fast. Riddle had said the potion was powerful, but she hadn’t thought about this. 

It looked like a small dick, and like a regular one, it got hard, which seemed to happen at inconvenient times. She found herself humping her pillow at night, afraid to touch herself, and during gym class, she’d spend time staring at the bodies of the boys, at their firm asses and strong arms. It wasn’t like she hadn’t had a libido before, but this was something else. 

She reached down and touched it, rubbing it between two fingers. It stiffened, slippery in her wet hand. Ace felt the twinges of pleasure beginning, could tell she was getting wet as well as hard. 

How did boys jerk off, anyway? She shut her eyes and wondered if Deuce was taking advantage of his time alone in their room to rub one out. Did he hold in his hand like this, flicking a finger over the head? It would be much bigger than hers, she was sure, imagining herself holding it in her hands. She felt the hood of her big clit, rubbing at the sensitive flesh beneath. It was uncut, she thought, vaguely amused. Was Deuce like that, or was his cock circumcised? 

Her fingers moved faster. It was like playing with herself before, only bigger, she told herself. Stop thinking of it as a dick. Girls didn’t have dicks, they had clits, and no amount of magical deformity could change that. To ground herself in that, she rubbed at her boobs. Girls had boobs. Boys did not. 

She wondered if Deuce moaned when he came, or did he just grunt and finish off, worried about making noise? Rubbing at a sensitive spot, she couldn’t stop a little moan of her own. 

“Hey, I think somebody’s jerking off in here.” 

Ace froze, praying the sound of the water had hidden things. 

“That’s right. The voice was hushed. “And I know who it is.” 

“Hey, Ace.” The shower curtain was thrust open and Ace was suddenly faced with about three other dorm members, all upperclassmen. “Having fun exploring that new body?” 

“G-get away from me,” Ace gasped, pale with fear. “You can’t just – “ 

“What’s the problem? We’re all men here, right?” 

“No,” Ace croaked, which made some of the boys grin. “Not me.” 

“You know you’re not supposed to pretend you’re a girl, Aceyboy,” said a junior, a mouse beastman. “I bet the housewarden would love to hear about how naughty you’re being.” 

Ace’s heart was racing. The boys had completely cornered her, boxed her into the enclosed space. 

“No, um, no I’m a boy,” he gasped out, cowering naked and wet. 

“I’ve been really curious what that potion has been doing to you,” said another boy, this one a brunette sophomore. “Let’s have a look.” He shut off the shower and moved in. 

“Please, don’t,” Ace tried to resist but it wasn’t hard for the boys to shove him against the tiled wall and expose his crotch. 

“Oh seven, he really is a boy!” 

“Look at that little dick!” 

“Think he’ll grow a beard, too?” 

“I think he’s more muscular. He’s like a whole different person under his clothes now.” 

Ace felt tears gathering in his eyes as his body was examined, then touched. The mouse grabbed at his clit, which hardened under the stimulation. This made the boys even more excited. 

“Wow, bro, you got hard from this?” 

“Yknow,” said a blonde junior, “It’s pretty mean to make Ace get naked like this. We should make it all more equal.” 

“No, don’t, Ace protested, but he couldn’t do anything as one by one the other students stripped out of their clothes. They were all in varying stages of hardness, which made him screw his eyes shut. He’d never seen dicks up close before like this. 

“Hey, man, you’ve made us all excited,” said someone. “What are you going to do about it?” 

Ace knew where this was going, and he weakly asked, “Don’t you think that’s, like, gay? Since I’m a guy?” 

The mouse boy laughed. “Dude, we’ve been at this school without any girls in forever. We take what we can get. And you’re the cutest boy we’ve seen in a minute.” 

Ace had no rebuttal to this. Did they really see him as a man? They hadn’t commented on his chest at all, really, as if that didn’t register. Instead, they were excited about his erection. 

“Get down on your knees and take care of your seniors,” The brunette boy said, a dangerous edge to his voice. Ace slid down to the floor, looking uncertain. 

“What do I do?” He asked in a small voice. 

“Oh my god, have you never done this before?” The blonde laughed, grabbing at his dick and grabbing Ace’s upturned chin with his other hand. “I want you to put your mouth on it, okay? Give it a few licks.” 

Reluctantly, Ace scooted forward, the tile cold on his bare knees. He gave the head of the boy’s cock a few licks, wrinkling his nose at the taste. 

“That’s it. Get your whole mouth on there.” 

Ace wrapped his lips around the dick and licked the underside a little. He wasn’t sure if he was doing it right. 

“How is he?” asked the mouse. 

“He’s really bad at it,” the blonde replied with a laugh. “Hey, Ace, I’m going to need you to suck on more than just the tip, okay? Let me show you how to suck dick like a man.” He grabbed Ace’s wet hair, moving him down his shaft. Ace choked a bit as the tip hit the back of his throat, but he couldn’t get away, not with his head held in place. 

“That’s it, nice and easy,” the man murmured. “Suck on it, and don’t you dare bite me.” 

Ace sucked on the thick cock invading his mouth, trying to pretend it was some kind of weird fleshy popsicle. He couldn’t stop himself from gagging a little, but he was doing his best. 

“Woah, he’s still so hard,” commented the brunette. “Ace, you can touch yourself if you want.” 

“Don’t distract him,” his friend grunted. “I’m close.” He bucked his hips forward, and Ace felt himself choking again, still trying his best to suck, to run his tongue along the other man’s cock. 

Then, without warning, his mouth was filled with a strange tasting liquid. Ace coughed and gasped, spitting out globs of white stuff that he realized with dawning horror was cum. 

“My turn.” The mouse pushed forward and shoved his cock in Ace’s mouth all at once. He gagged, unable to breathe. This one was a little longer, but thinner, angling down his throat torturously. 

“Go on,” the other man said, “Blow me.” 

Ace did, growing ever more aware of how hard and wet he was. The other boys noticed, of course, the blonde one getting down and teasing it with his fingers as her was made to suck on the mouse boy’s heavy balls. When he came, he pulled out and shot his load on Ace’s face, splattering his face and hair with cum. 

“Hey, little guy,” the brunette boy said at last, shoving his bare foot between Ace’s legs. “I remember how my puberty was. You’re probably horny all the time, aren’t you? That’s how it is when you’re a dude.” He ground his foot against Ace’s cock and front hole. “Look at you hump my leg like a dog. That’s what you are now, Ace. A slutty little puppy humping everything he sees.” 

“No, I’m not,” Ace whined, but he was losing the battle, his hips jerking forward, trying to get friction on the other man’s foot. He couldn’t control his moan as the man lifted his leg a little, dragging along his core.” 

“You know you want to,” he said. “Hump my leg while I fuck your throat.” 

With that, he thrust his cock into Ace’s mouth. This was the roughest by far, holding his hair tightly as he jerked his head back and forth. Ace felt tears come to his eyes as his throat was battered. He could barely breathe. 

Still, he couldn’t stop himself from grinding on the other student’s leg. The friction made him feel crazy, made him feel like he was falling, only held in place by the fingers in his hair. What had his old name been again, anyway? The taste of the cock fucking his face was making him forget. 

Ace gave up resisting and kept humping the man’s foot, stimulating his clit, no, it was his cock, his slutty cock, the thing making his brain feel fuzzy, or was that the lack of air? He couldn’t breathe anymore. 

All of a sudden, the world seemed to explode in a white flash of intensity, making him slump forward on the cock in his mouth. 

“Did he just come?” Someone spoke as if from far away. 

“Fucking slut, he came on your foot. It’s all slippery.” 

Then, hot cum poured down Ace’s throat. The brunette kept a firm grip on his head, holding him on his softening cock until Ace had swallowed it. Then, he pulled him off, dropping him unceremoniously on the floor. 

“I bet that was his first time coming as a man, huh.” 

“How’s it feel to orgasm with your dick?” 

“Come to us next time you get a boner, okay? We’ll give you a good time.” 

Ace curled up on the ground, breathing hard. The blonde boy leaned down, said, “Thanks, puppy,” and gave him a kiss on his cum-splattered face. 

“See you later, Ace!” The boys dressed and left, leaving him shaking on the bathroom floor. 

With great effort, Ace staggered to his feet and turned on the shower, washing the filth from his body, trying to hold himself up. He couldn’t stop shaking. His throat hurt. 

The boys had taught him that he’d been very, very wrong. Girls did not act like he just had. He really was like a dog, something filthy that allowed himself to cum on someone’s foot, to let them fuck his mouth like a whore. 

He felt dirty and ashamed, trying to wash the cum from his hair. However, he was even more ashamed to realize that he wanted more.
