“Hey Fluttershy, I’m bored!” Sweetie Belle’s voice rung out through Fluttershy’s cottage. Sweetie Belle looked around, and idly kicked a fold in the carpet on the floor. While she’d been excited to be invited to a sleepover at Fluttershy’s home, she was tired of waiting for Applebloom and Scootaloo to arrive. It’d been an hour. They had to arrive soon.
 
Fluttershy poked her head around the doorframe. “Huh Sweetie? What’s up?” Sweetie Belle looked up from the carpet. “I’m bored! I’ve been waiting for the others to arrive for ages and ages and there’s nothing to do round here! I played with Angel for a bit but he got bored and went to bed! Have you got anything we can do?!”
 
“Well,” Fluttershy smiled coyly, as she stepped round the doorframe into the room. Sweetie Belle’s jaw hit the floor. Between Fluttershy’s legs hung an impressive set of genitals. A pair of hefty balls swung slightly behind a thick, twitching penis that dragged along the floor. “W-where did THOSE come from?” Sweetie Belle was aghast. “Oh, these?” Fluttershy smiled, looking down at her genitals. “Twilight showed me a special enhancement spell she’d been developing on Shining Armour. Turns out to do rather… surprising things to us ladies.” She looked up, and caught Sweetie Belle’s gaze. She was drooling slightly, staring at Fluttershy’s undercarriage. Fluttershy smiled. “Hey, if you were bored, we could always play a special game I know, if you like?” Sweetie Belle broke her stare, and quickly wiped the small string of drool from her chin. “Y-yeah, alright then! What did you have in mind?” Fluttershy walked forward, and slowly paced around Sweetie Belle. As she moved, a small trail of pre-cum dripped out from underneath her, marking the floor as she went. She settled in front of Sweetie Belle, and laid a hoof on the back of her head. “The first thing you could do, is have a taste. I bet you’ll really like it! Open wide now…”
 
Sweetie Belle opened her mouth, as Fluttershy pushed her head towards her crotch. Sweetie slowly wrapped her lips around the vast head of Fluttershy’s cock, before stopping, getting a feel for the size and shape of Fluttershy. But then she felt the hoof at the back of her head pressing forward, as she found Fluttershy’s member sliding down her throat. Inch after inch, until eventually she felt her nose pushing into Fluttershy’s stomach. An audible groan emanated from the mare above her. Sweetie Belle gagged. She’d never done this before, and she didn’t know what she needed to do. She pushed her front hooves against Fluttershy, trying desperately to get the vast cock out of her mouth. But Fluttershy was still holding her head in place, groaning to herself. Just as Sweetie Belle started to gag again, she felt her head being pulled backwards. The huge cock slid back out of her throat. “Thank goodness!” Sweetie Belle thought to herself. But at that moment she felt herself being shoved forwards again, as Fluttershy bottomed out inside her mouth again. “MMMPH!” Sweetie shouted, but to no avail. Fluttershy started to buck her hips forwards and back, fucking Sweetie Belle’s face with increasing speed and violence. She shifted on her flank, trying to get comfortable as Fluttershy’s crotch slammed into her face over and over, when she suddenly heard a cry of pleasure from Fluttershy, as a torrent of hot cum flowed down Sweetie Belle’s throat, straight into her stomach. It lasted about ten seconds, but to Sweetie it felt like an eternity. Eventually, the wave stopped, and she sighed as Fluttershy withdrew her cock from Sweetie’s mouth, with an audible pop as the head fell from her mouth. Sweetie fell backwards onto the floor, lying on her back. She couldn’t believe what had just happened. She hadn’t even noticed Fluttershy pacing around her again, as she slowly lined up her penis with Sweetie’s vagina.
 
Without warning, Fluttershy plunged into Sweetie Belle again, bottoming out inside her immediately. There was no going slow this time, as Fluttershy thrashed brutally against Sweetie Belle’s undercarriage. A euphoric gasp escaped Sweetie’s lips. “Are you having fun now, Sweetie?” Fluttershy asked smugly. Sweetie Belle could do nothing but smile as the weighty length slammed in and out of her, pre-cum being flung out onto Sweetie Belle’s body, dripping from her pussy. But just as suddenly as the first time, Fluttershy gritted her teeth as she came again with full force. Cum flowed from her cock, filling up Sweetie Belle’s womb, as she felt her body beginning to swell.
 
“FLUTTERSHY!!!” Sweetie Belle managed to cry as her stomach started to push up into her field of vision. Finally the flow slowed to a drip, as Fluttershy slowly slid her cock out of Sweetie Belle, pulling herself free. A wave of cum flowed out of Sweetie Belle’s now gaping vagina, soaking into the floor and carpet. Fluttershy slumped to the floor, and Sweetie Belle’s head lolled to the side. “After that little game, I guess we could both just go to sleep now…” Fluttershy voiced through a stifled yawn. “…that’s a good idea, Fluttershy. That game really…tired me out. Goodnight.” Both Fluttershy and Sweetie Belle fell asleep where they were, as cum slowly pooled around them, still flowing slowly out of Sweetie Belle onto the floor.
