1 - In which Miss Screwball introduces herself and makes a houseguest comfortable

Silver Spoon was thoroughly unsurprised when there was no immediate response to her knocking on the door to Diamond Tiara's apartment. She also wasn't particularly caught off guard when there was no response for several minutes. This was all, as far as she was aware, normal behaviour for Diamond Tiara. In retrospect, it should have been taken as a bad sign that there was absolutely no response whatsoever – not even so much as an irritated muffled “fuck off I'm sleeping.” But, as it was, she just assumed that Tiara was hung over from partying the previous night.

She of course had a key, specifically for this kind of situation. She unlocked the door and barged inside. “Tiara, get your ass out of bed. We've got an econ lecture in an hour and you specifically said that if I let you miss it because you got drunk and hid in your bedroom again you'd kill me.”

No response. Again, not unusual, but a bit more obviously not normal. Usually there would at least be some swearing, maybe a shout to shut the fuck up followed by pained groaning. Perhaps Tiara had already left? Or, more likely, she'd been somepony's one night stand.

Silver frowned. She never got invited to parties. And when she did – usually as Tiara's hanger-on – she never got to be anypony's one night stand. Wasn't half the reason she was friends with Tiara in the first place to help her get popular? That, and Tiara was that happy-yet-rare combination of obscenely rich and incredibly generous to her friends. And Silver Spoon had managed to successfully be Tiara's only real friend for almost twenty years. Still, she wasn't quite sure what Tiara had that she didn't.

Well. Aside from money. And her mother's figure. And her mother before her. And her mother's mother's mother, going back down the family tree for generations. And the ladies on her father's side of the family tree to boot. Tiara came from a long line of beautiful mares. Thin, tall, willowy. Like a supermodel. Hell, her mother was a supermodel.

And meanwhile there was Silver Spoon. Awkward, chubby, nerdy little Silver Spoon who somehow managed to befriend rich, beautiful Diamond Tiara at a young age and had hated herself ever since.

To say nothing of how much she hated Tiara. Tiara was a cunt. She used her money as a substitute for her complete lack of a personality. Their friendship consisted of Silver awkwardly following her around as she spent exorbitant amounts of money on herself, hoping that maybe she'd accidentally buy something for her as well.

“Tiara, if you're even here at all, get the fuck up or I'm leaving and you can be fucking late for all I care.” She took a few steps into the apartment. “And if you're not here then I'm not fucking looking for you.” She winced as something large and heavy moved across her feet. She kicked, gently so as not to hurt the very large snake that Tiara kept as a pet for some ungodly reason. But it wouldn't do for it to escape because Silver hadn't bothered to close the door. “Go on, you stupid thing, get away from me.”

The enormous creature – easily four times longer than Silver was tall – lethargically slithered out of the patch of light let in through the open door, back into the darkness of Tiara's apartment. Silver groaned. The thing – Tiara had named it Princess, but Silver was content to just call it “the thing” – was probably most of the reason that Tiara never brought any one night stands back to her place. Having a twenty foot snake crawling all over the place was something of a boner-killer.

“Tiara, this is the last time I'm calling for you. Get your fucking ass in gear or I'm leaving.” No response. Silver waited for a few moments, the apartment deafeningly silent. “Come on, do you know how hard a time I have getting them to even let me in the building? Let alone letting me head up to the penthouse suite. Don't make this have been for nothing.”

The door slammed shut behind her, plunging the apartment into complete darkness.

“Heeeeeeeey, Silvy~ So very nice to see you today~”

The voice was definitely Diamond Tiara's. Silver Spoon had known Tiara for eighteen years, she knew that voice like the back of her hand. But had she not known Tiara as well as she did, she would absolutely not have been able to tell.

Hell, she still wasn't quite sure it wasn't an entirely different pony in Tiara's home. It would be easier to tell with some lights on. “Tiara, this isn't funny. Stop dicking around, we've got to get to class.”

“Mmmm, Tiara ain't home, hon. And I can promise you there will be plenty of dicking done today~” It was lower, Silver decided. That was the main difference. Husky, but with a lilting, melodic quality.

But none of that really mattered right now. “Tiara, seriously, I'm not in the mood for games,” she said, turning around to face where the other mare presumably was.

“Toldja, hon. Tiara ain't home.” The lights flicked on. “Or at least, mostly ain't home. Hadn't quite finished up getting ready when you got here – lucky you, you get to see the good bit.”

Tiara was completely naked. That was the first thing Silver noticed about her. That, and that she was actively masturbating. She had three fingers knuckle-deep in her glistening cunt, and her other hand held a large glass bottle filled mostly to the top with a clear, viscous fluid. “Oh, god, are you fucking drunk? It's ten in the fucking morning you fucking lush.”

She certainly looked drunk. Her cheeks were flushed a deep red beneath her pink fur, and her eyes were heavy and half-lidded. And there was something else off about them – if Silver didn't know better, she'd say they were violet instead of their usual cold blue. Maybe she was wearing coloured contacts? Or maybe it was just the dim lights of Tiara's hallway playing tricks on Silver's eyes. But somehow that didn't feel like an adequate explanation for how... wrong Tiara's eyes felt.

“Oh, this?” She lifted the bottle and sloshed it around. “It ain't booze. Something much better'n that, trust me. Tiara's only had a sip and, well, you see me now.” She grinned, a lopsided, goofy grin. “Was about to see what a whole bottle does when you showed up. Just in time for the real show to begin.” She held the bottle out, shoving it into Silver's face. “Unless you'd like a taste? I've got plenty more of these, I'm sure I can spare a little for Tiara's PFF~”

“Tiara we've got class, now's not the time to get – eugh!” Silver caught a whiff of the fluid in the bottle and gagged. It was musky, and overpoweringly sexual. “Tiara! Why the hell did you drink that stuff?!”

“It was a gift~ From someone very special. Or at least someone you don't turn down gifts from if you don't want to get turned into a fish or something.” She shoved the bottle into Silver's face a few more times. “You suuuuuuuure you don't wanna taste?”

“Wait, hold on, you got given booze by fucking Discord?”

“Yeppers~ You know, Tiara used to be afraid of him? No idea why, he's so much fun~ You sure you don't want some? Oh, well, more for me!” She pulled the bottle back, put it to her lips, and chugged. The thick, syrupy liquid slowly slimed its way down her throat. A single stream of the stuff drooled out of her mouth and down her chin, dripping onto the floor below her. She moaned lewdly into the bottle, her fingers picking up their pace. When the bottle was empty she forcefully tossed it aside; it hit the wall a few feet away, shattering loudly. She belched loudly. “Aw, yeahhhhhhhhh, so fuckin' good~” Her now free hand moved to a pert breast, furiously pinching at her erect nipple. “'s been so long since I got to come out to play, Silvy. Oh, we're gonna have so much fuckin' fun~”

Silver took a step back. Away from Tiara. “Oh, no you don't.” Tiara gestured, and Silver felt a pressure on the back of her head. And then, with another gesture from Tiara, she fell forward onto her knees, pulled along by some invisible force until she was face-to-cunt with her best friend. “I mean, my fingers are nice and all, but what'd be even better is your tongue. Now get to licking, pet~” With that, the invisible force pushed against the back of her head even harder until what resistance she could put up was overwhelmed and she was shoved face-first into Tiara's glistening pussy. “Don't fight it, bitch. 's better for you if you just accept your new role as my little slut, or else I'll have to use force~ And you don't want me to have to use force. Trust me.” The threat was punctuated by a feeling of tightness in her mouth, and Silver quickly opened her mouth and took a tentative lick of Tiara's box before the threat could be carried out. The taste was unlike what she had expected – slightly sweet, slightly salty, very slick. She was unsure if this was unusual because this was her first ever sexual experience that involved another active participant, and she'd never tasted her own fluids.

It wasn't unpleasant, though Silver rather forcefully reminded herself that she was being raped. She continued lapping at Tiara's juices, occasionally dwelling on her swollen button as Tiara grasped her head tightly. “Mmmm, you're really shitty at this, you know that? Guess Master's just gonna have to teach her little slut how to be a less terrible pet. Put some enthusiasm into it, whore.” She groaned, deep and throaty. “Nnnnng, it'll do though. Hey, Silvy. Open wide and you'll get a treat for good behaviour~”

Silver, terrified of the potential consequences of not doing what she was told, tentatively opened her mouth.

And felt something long, firm, and burning hot force its way deep into her throat. She gagged violently as she found herself suddenly deep throating Diamond Tiara's brand new cock. “If you can't be assed to put effort into your oral, I guess I'm just gonna have to take the initiative. Brace yourself for a good facefucking, pet.”

Silver let out a muffled groan of protest, slamming her hands against the wall and door behind Tiara as she tried very hard to ignore how good this felt. She knew that it wasn't unusual for rape to feel good – the body's natural response to sexual stimulus was to feel pleasure, regardless of the source. But this didn't feel like just some instinctive reaction somehow. There was something about it that felt real. An intense heat that filled her body as Tiara's cock grew and grew, pushing itself further and further down her throat. She felt a pressure on her chin that she only assumed was a set of balls – Tiara was holding her so tightly and so close to her that all she could see was her pink navel. A pink that seemed a few shades darker than it usually was, something that Silver might have attributed to a dye job or trick of the light were there not a good foot's worth (and growing) of tangible evidence that Tiara had physically changed shoving itself deeper into her gut.

She stopped banging her hands against the walls. It wasn't like she felt short of breath. She should have – Tiara's monster dong took up all of the space in her throat, leaving no room for her to breathe. But her no longer needing to breathe was hardly the most farfetched thing to happen to her this morning. Instead, she put her hands to better use. One, she used to steady herself by grabbing Tiara's pert ass; the other, she used to grope her balls. They were enormous, the size of fists. And heavy, too. And hot, a pulsing heat that sent erotic shivers down Silver's spine. She gave the one she was grasping a squeeze, groping and exploring it.

“Yessssssss, good pet. That's more like it, whore.” Silver felt an odd satisfaction from the degrading names Tiara threw at her. Her heart raced at the praise, and she intensified her efforts in an attempt to earn more. “Harder, bitch.” She obeyed, tightly clutching at Tiara's ballsack, with far more force than should by all rights have been safe, like it was a stress ball. “Come the fuck on, you weak cunt. I'm not made of glass, Silvy~ I want you to really hurt me, maybe draw some blood~”

Tiara pushed against the back of Silver's head even harder as Silver intensified her efforts. “Or maybe you'd rather be the one getting hurt? Well, slut? You want to be punished for your failures? Because I gotta say, this is a pretty fuckin' weak BJ.” Silver groaned again. Good god, she'd never been talked to like this before, but it felt soooooo fucking good. There was only one thing that could make it feel better, and suddenly she realized the way to get it.

She pushed her face as close to Tiara's belly as she could get it, pushing upwards with her tongue, and slowly moved her hand down and around the ballsack, searching underneath it for – yes. There it was. She would have grinned were it not for the gigantic penis taking up her entire mouth. Looks like Tiara still had a cunt to play with. That was phase one of her plan; phase two was to move her other hand inwards, inching closer and closer to Tiara's buttcrack and her other prize.

Simultaneously, she shoved a finger up Tiara's cunt, another into her asshole, and bit down on her cock as hard as she could.

“Hnnnnnnnfuckyessssssssssss,” Tiara moaned, her cock surging in size. “That's more fucking like it, cunt! Hope you're ready, 'cause you just pushed me over the eeeeeeeeeeeeedgefuckkkkkkkkkkk.”

Silver Spoon felt the underside of Tiara's cock bulge, starting at the base – pushing her teeth apart, she noted as she put as much pressure on the cock as she could – and slowly moved up the length of the shaft until it exploded out of the top.

Silver gagged as she felt the cum filling up her belly and rushing upwards through her throat. She felt it pushing at the airtight seam formed by her mouth and Tiara's cock. She felt it spray out of her nostrils – the only available hole for it to escape from – with the force of a firehose. She felt her belly swell out and out and out as the output of Tiara's cock vastly outpaced its ability to leave her body.

And then, after what felt like an eternity, she felt the flow slow down and eventually stop. Slowly, Tiara let go of Silver, and her mouth slipped down and down until, with a pop, she was freed of the mammoth cock that had been shoved down her throat for the past twenty minutes.

“Holy shit.” She panted heavily, fighting to catch her breath. “Tiara, what the fuck was that?”

The pony that used to be Diamond Tiara stretched, pushing out her modest tits. And she was definitely not Tiara anymore – even discounting the darker pink of her coat, the darker purple of her mane, and the eyes, a dark purple with a black spiral instead of pupils – her cutie mark was undeniably different. No longer was her flank adorned with the image of a tiara. Instead, there was a baseball and a screw.

“Like I keep saying, pet. Tiara's gone.” She idly took off the tiara that she wore at all times, idly examining it and frowning slightly. She gave it a shake, and it transformed into a yellow-and-orange vertically striped beanie, topped with a neon green propeller. Nodding with smug satisfaction, she popped it back on her head at a jaunty angle and grinned, showing off unsettlingly pointed teeth. “It's Screwball's time to shine.”

“Okay, Screwball. Whatever. You haven't answered my question.” Silver made an attempt to get up, and failed as her sloshing belly pulled her forward. She groaned, resigning herself to leaning on it like a waterbed – it was large enough that her head was basically level with where it would be if she were upright anyway.

“You're taking this rather well. I just raped you. With a penis. That I grew with magic. And pumped you so full of cum that you're immobile.”

“Yes, well, Discord is involved.”

Screwball shrugged. “Fair enough. So, um.” She awkwardly walked over, and Silver idly noticed that the cock had just sort of vanished at some point. “How was it? I didn't rape you too hard, did I?”

“That's kind of a stupid question.”

Screwball huffed indignantly. “Well, excuse me for caring about your well-being. Sex isn't fun if it's unpleasant, rape or no. And, um.” She awkwardly grabbed Silver's belly, giving it a gentle squeeze. “In case you couldn't tell, I've got a bit of a habit of letting things get... excessive.”

“No fucking kidding.” Silver rubbed her belly herself. “No, it doesn't hurt. It should, but it doesn't.”

“Well, duh. I mean, I've got fucking magic powers. I can make it so you don't need to breathe, I can make it so you can take three feet of cock down your throat. And yeah, I can make it so you can take enough cum to make you look like that without exploding. I can do fucking anything.”

“That's nice. Where did my clothing go?”

“I made it go away when I started fuckin' your face.” She shrugged. “I mean, would you rather it have been wrecked? You've still got class later, after all.”

“I think that this,” she slapped the taught skin of her belly, “is going to be a bit of a bigger obstacle for that.”

“Pft, it's gone.” And so it was. Silver was standing upright, clothed and clean. “Anyway, you haven't answered my question, miss.” She jabbed Silver firmly in the boob. How was it?”

“Well,” Silver blushed. “It, uh, wasn't exactly... unpleasant.”

“Aaaaaaand?” Screwball grinned.

“And I wouldn't be averse to doing it again. Now can we go to class?”

Screwball clapped, squealing with delight. “Oh, yes! Hahaha!” She threw her arms around Silver, drawing her into a tight hug. “You are gonna be the best fucktoy ever, Silvy! I promise, you'll fucking love being raped and raped and raped until your capability for rational thought beyond a desire for more sex is completely destroyed!”

“Uh.”

“Oh, but before you leave, there's one last thing I need to do.” She shoved Silver away, holding her by the shoulders at arm's length. “We need to fix your fashion sense. What you've got on now is simply too frumpy to be acceptable! You dress like someone's eighty year old grandmother!”

Silver blushed and crossed her arms. “I do not!”

“Oh, please, a long sleeved shirt and baggy jeans? I bet you've got granny panties on under all that too. No, we're going to have to completely overhaul your outfit from the ground up. I'm thinking no shoes. Shoes are lame and gay. As for your pants, they don't show nearly enough skin. How about some Daisy Dukes instead. No, no, no,” she frowned at the glorified panties that had replaced what Silver had been wearing before.

“Skimpier! Like a denim thong! And a few sizes too small, too, so it rides up in your buttcrack and your cunt so people can get a good look. Wait, no, don't make it smaller, better idea. Let's make your butt bigger. No, bigger. Bigger, dammit. I'm talking broodmother levels here. Woah, okay, no, too big. Bit silly looking for day-to-day life. I mean, could be fun to fuck an ass bigger than I am. Yeah, that's more reasonable. Ghetto, but realistically ghetto. Now, for your top. Hmmm.” She crossed an arm across her body, resting the elbow of the other arm in its hand and tapping her lips, her face contorted in an exaggerated thoughtful expression.

“The arms can stay. Actually, no, make them tighter. Show off your slender, athletic arms. Yeah, like that. The hem, though. Yeah, that's gonna need some work. Tight sweaters can be sexy, but they're a lazy shortcut that nerds with big boobs use to look hot. We can do better. Take that bottom hem up. No, higher, midriff is nice, but let's get some underboob. More underboob. More, dammit, I wanna see some nipple. Okay, hold on, I see the problem. Tits ain't big enough. Let's just fix that, I'm thinking about head sized would be a good default? Yeah, that looks good. We can always make 'em bigger if we wanna. Oh, and while we're at it let's just tuck in that tummy a bit, give you a six-pack annnnnd a little bit of plush over that. Some nice cushioning~ And now let's just plunge that neckline. Lower. Lowerrrrrrr I wanna see some areola on the top as well. Hm. Actually, no, that kind of looks silly with the full arms. Would look better as a tube top no I didn't mean to actually make it a tube top let's just go back to before I fucked with the neckline. God damn. Finicky bullshit.” She frowned. “Know what? Fuck the neckline. Let's just open the top up, like a jacket, and put that tubetop from before under it. Yesssssss, that looks good.” She gave Silver Spoon a thumbs up. “Now you look like a class-A cumdumpster!”

“I kinda don't want to look like a class-A cumdumpster.”

“Oh, you say that, but you're gonna enjoy this. I promise! Now go on, get to class! Show off your new sexy bod and maybe fuck a few dudes!”

“Can I at least have some shoes?”

“No! Shoes are lame and gay, weren't you listening? “

Silver sighed with exasperation. “Look, going barefoot all day would be more feasible if we went to school in Appleoosa, but this is Trotsford. Urban environment, lots of concrete.”

“Do you really think I'd make you go barefoot and not give you feet that can take walking barefoot on concrete all day?”

“But-”

“The only butt I wanna hear about is yours, getting ploughed by a well hung stallion! You need the practice to properly service your mistress, pet~” She gave Silver a good shove. “Now get going! The lecture starts in ten minutes and we're only directly outside of the lecture hall! If we don't hurry, we'll be late, and Tiara might fail!”

“Uh, Screwball?”

“Yes, pet?”

“You're still naked.”

“Yep!”

“... Aren't you gonna magic up some clothing for yourself?”

“Clothes are lame and gay. Let's get to class!”
