The Futa Cutie Mark Crusaders Have Their Ways With Diamond Tiara, But She's Not Necessarily Entirely Against It

Being a filly with a masochism fetish was not easy. It didn't help that the only dominant fillies in the class were only mediocre sadists at best. It started out fun, with words like 'blank flank' and 'Dumbelle' being thrown about, but after awhile, it lost its touch. And so had they.

That was why Sweetie Belle took the most dominant of the two, one Diamond Tiara, lured her to her bedroom whilst her parents were out doing their jobs, drew the curtains, and then locked the door.

"W-What is this?!" Diamond Tiara asked as Sweetie Belle slowly approached her, a catlike grin on her face. "You tricked me! This isn't yard sale!" Granted, they were not in a yard, but Diamond Tiara just assumed that Sweetie Belle was too poor to afford one. She had been lured by the promise of cheap toys, dresses, and fashion accessories, but now…

"Yeah, I trick you," Sweetie Belle admitted, biting her lip as she stopped just short of Diamond Tiara. "What're you gonna do about it?"

Diamond Tiara was fuming, but she had no time for this. "I'm leaving!" Sweetie Belle stepped to the side to block Diamond's path, and then again when Diamond Tiara tried to circle around her. "Get out of the way, Dumbelle!"

"Ohhhh yeah," Sweetie Belle said, licking her lips as her horn lit up. "I made you angry, didn't I? Bet ya just wanna hit me real hard, don't ya?"

Diamond Tiara raised an eyebrow. Now she was just confused. "W-What? Why would I-" Suddenly, Diamond's hoof was lifted in a glow of green magic, and then it swung out and struck Sweetie Belle's face. She gasped and took a step back. "I-I didn't-"

Sweetie Belle rubbed her cheek, a tear in her eye but her mouth still curled into a grin. "That all you got? C'mon, I thought you were angry."

"I-I am, but I'm not gonna-" Suddenly, Diamond's hooves were pulled forwards, and the filly had inadvertently pushed Sweetie Belle onto her back. "S-Stop that!"

Sweetie Belle spread her hind legs, revealing a large appendage between them. "Oh noooo," Sweetie Belle 'cried', making no effort to hide the throbbing erection from Diamond's eyes. "You discovered my secret! Please don't tell. I'll do aaaaanythiiiiiing."

Diamond Tiara blushed and turned away. "W-What?! That's gross!"

"Ohhhh yeah, that's it!" Sweetie Belle panted, using her magic to lift one of Diamond's hind hooves and slam it into her cock. She moaned, and asked, "What else? Is it sick? Am I disgusting?!"

Diamond Tiara wanted to confirm this, but felt that it would be a loss somehow. So she simply stayed silent, not sure of how to win this fight.

"Say it," Sweetie Belle said, driving Diamond Tiara's hoof harder onto her rod.

"S-Stop-"

"Say. It." Sweetie Belle panted as small beads of liquid dribbled from the tip and onto Diamond's hoof. "Tell me how much of a freak I am. How you want to beat the crap out of me and my disgusting penis."

Diamond Tiara cringed. "Uhhh, y-y-y-you are… unpleasant."

Sweetie Belle rolled her eyes. "Okay, Rarity. Now try putting some feeling into it!"

Diamond Tiara felt her hoof rise and then slam down on Sweetie Belle's shaft. She cringed, knowing that that must have hurt. "Why are you doing that?!"

"Ohhhhh yeah! That's it, punish me for being such a dirty filly! Yell at me and tell me I deserve it!"

"What are you talking about?!" Diamond felt her hoof being raised and lowered again, this time faster and harder. "Stop that!"

"Or what?" Sweetie Belle teased. "You gonna spank me, Di?"

Diamond felt her eye twitch. That nickname was reserved for her best friend, Silver Spoon. "I-I'll…"

"You'll hit me, won't you?" Sweetie Belle rose to her hooves and grabbed Diamond's foreleg, bringing it across her face with a slap so loud that it echoed. She cried, yet she still approached Diamond Tiara. "Or maybe you wanna bite this disgusting little filly?" She placed her hoof into Diamond's mouth, hoping that she would bite down. But she didn't.

Diamond simply retreated and spat several times. "Yuck! Blegh! Disgusting! Filthy!"

"AHHH! That's iiiiiiit!" Sweetie Belle writhed her hind legs as she resisted the urge to cum. There was still more to enjoy, and she didn't want it to end just yet. "Tell me more, Diamond! Tell me what a bitch I am!"

Diamond couldn't handle it much more. "You're a freak!" she shouted, startling Sweetie Belle but pleasing her nonetheless. "You're a weirdo! A moron! A… A… A FUCKING SLUT!"

"OHHHHHHHH!" Sweetie Belle shot strands of thick white liquid all over her floor, prompting Diamond to jump back with a yelp. "OH YES YES YES YESSSSSSS!"

"EWWWW!"

As Sweetie's orgasm came to an end, she panted and stared blissfully into Diamond Tiara's eyes. Her cock was still hard. Coming once wasn't enough. "Yeah, I'm a slut, aren't I?!" Sweetie Belle grabbed Diamond Tiara fell onto her back, spreading her legs once more and feeling the tip of her rod poking Diamond Tiara's surprisingly-moist entrance. "I bet you wanna teach this slut a lesson, don'tcha? You wanna rape me 'til I break? Make me your bitch?!"

"How could this possibly be rape?!"

"You wanna make me your fucktoy?! Your little cum bucket?!"

"I don't even know what that is!"

Sweetie Belle groaned. "Just say 'yes'!"

"Yes!" Diamond Tiara shouted without thinking, and then, she felt her hips being lowered by Sweetie Belle's magic, and felt herself being filled by that thick, disgusting stick of flesh between Sweetie Belle's legs.

"Oh noooooo!" Sweetie Belle cried with a smile. "I'm being raped, and my parents aren't home so it doesn't matter how much I screeeeeeam!"

Diamond Tiara tried to lift herself off, but Sweetie Belle's magic was acting as a barrier, only allowing her to pull out to the tip. "A-AHHHH! NO!"

"Hit me, Diamond!" Sweetie Belle demanded. "Hit me!"

"I don't want to-"

"Hit me!" Sweetie Belle's magic grabbed Diamond's hoof and forced it across her face. That one drew some blood. "HIT ME!"

Diamond closed her eyes, and smacked Sweetie Belle with her other hoof. She didn't want to at first, but after two or three, she realised that Sweetie Belle didn't mind, and that it wasn't doing any serious harm… that she could see. Still, it felt unpleasant.

Sweetie Belle felt the reluctance through the pain decreasing, and her boner was threatening to go on strike. She decided that physical violence was too much for her mistress for the moment, and decided to try something easier. "Call me names again," Sweetie Belle said. "Tell me how much you hate me. How you're gonna milk my fat, disgusting dick like the cow I am."

Diamond Tiara raised an eyebrow. Why was Sweetie Belle so insistent on being called such vulgar terms? Still, if it meant she could stop hitting her… "Y-You're an idiot…"

"And?"

"Y-You're… demented?"

"Y-Yesss! I'm a freak, aren't I?!"

"Well, yeah, but… MM!" Somehow, Sweetie Belle seemed to grow even bigger inside of Diamond Tiara, and it felt… nice. Was it because of the insults? "Uh, you're ugly?"

"How ugly?"

"U-Ugly as a mule… 's butt! A-And you smell like one, too!" The cock inside her throbbed, and the pleasure increased. Diamond began to rock her hips unconsciously. "A-And I hate you! I hate t-that you're making me do this, so I… I…"

Sweetie Belle was close. She just needed to give Diamond a shove. "You think I'm a dirty, disgusting piece of filth, don't you?"

"Of course I do! Look what you're making me do, you… you… DAMN DIRTY BLANK FLANK!"

Sweetie Belle used her magic to halt Diamond's hips, catching the other filly off guard. She was close. They both were. But…

"N-Noooo! I need to cum!" Sweetie Belle shouted, wriggling uselessly under Diamond Tiara. "M-Make me beg for it! C'mon!"

"What? B-Beg for… Uhhh, i-if you wanna 'come' so bad, then…" Diamond Tiara thought for a bit. There was a movie she watched once, which her father shut off just as the mare did something to the stallion… She held out her hoof and said, "K-Kiss it."

Sweetie Belle's eyes lit up. She reached forward and kissed, licked, slurped… and practically worshipped that hoof.

The drool, however, was unnecessary, and Diamond Tiara pulled back with a whine. "EWWW! I SAID KISS, YOU MORON!" Diamond Tiara forced against Sweetie Belle's magic, grunting and eventually breaking it with some effort. "That's it! You're a filthy, disgusting freak, and I'm not gonna let you tell me what to do!"

Sweetie Belle panicked for a second, until she felt Diamond Tiara riding her like there was no tomorrow. "A-AH, W-WAIT!"

"NO! I'm ending this, so I can leave!" Diamond Tiara bucked like her life depended on it – because frankly, she felt that it did – and soon felt Sweetie Belle's thing burst inside of her, gushing her hot fluids all over Diamond's vaginal walls.

Diamond Tiara came, too, finally stopping her thrusting as she squirted all over the other filly's hips and her legs.

As the two came down from their highs, Diamond Tiara climbed off and collapsed onto the floor. Sweetie Belle's cock retracted into its sheath, and turned her head to look blissfully at Diamond Tiara, the pink filly's belly rising and sinking… with a spot of cum clearly visible, and dribbling down.

Sweetie Belle beamed, and suddenly felt herself ready for another round. "H-Hey, looks like I got some on you," she said, climbing to her hooves. "Clearly, I still need to be punished. Perhaps a spanking to help me remember?"

Diamond Tiara turned her head slowly, watching as Sweetie Belle approached her bed, reaching under it and pulling out a paddle. 'No.' Bolting to her hooves, Diamond Tiara ran to the door and unlocked it.

Sweetie Belle heard this, and turned around. "Ah, wait!" Diamond Tiara was out of there before Sweetie Belle could even move, and the white filly was left on her own, throwing her paddle to the floor with a moan. "Ohhhh! I knew I should've started with the paddle…"
