Wonderful, Wonderful Lessons
Rainbow’s heart damn near stopped as she walked into the dorm room she shared with Fluttershy. The two had been at the school for maybe two years and while many parts of it could be lame, rooming with your best friend wasn’t one of those. Rooming with your best friend who had a footlong cock that was as thick as her arm, at minimum, and tits the size of your head? Even better, especially when you walked in to see them laid back on the bed, doing homework while wearing nothing.
Rainbow fidgeted for a moment, debating on what to do. After all, Fluttershy wasn’t always like this. In fact, before a few months ago the poor pegasus would have screamed had Rainbow caught her in her underwear. Now that they were both eighteen though, the stallions and mares of the school had started hitting on Fluttershy hard. The pick up lines had been driving her near to the brink of insanity, while Rainbow’s increasingly hard, advanced courses were driving her stress through the roof.
That had led to the first time they fucked. Things had changed so much since then. Not that everytime Fluttershy was naked she wanted to fuck. The mare was into nature after all, so Rainbow took what she considered the safer approach and said, “Ugh. Today was way too-”
“Get over here and suck your mistress’s cock like a proper bitch, slave.”
Fluttershy hadn’t even looked away from her assignment, a fact that made the shiver that the words sent through Rainbow’s spine into a full on hysteria. She had been hoping this was the case after all. Just one look at her owner’s cock was enough to make her a sopping wet mess, something the racer showed all too eagerly as she stripped off her shorts in a practiced motion on the way to the bed.
Fluttershy didn’t even look up as she leaned back a little, an annoyed sigh leaving her lips. Rainbow paused at the noise, but a leg lifting up to kick her, a long ago agreed upon punishment, made her not wait. Her mistress would speak when she felt like it. The slave was to focus on pleasing her, something that made Rainbow grip the bed as she got onto all fours.
Fluttershy’s cock currently was as soft as it ever was. When one packed as much meat as her it could only give so much Rainbow’s hands found as she lifted it slightly. It didn’t care for what was coming. No, it only cared about the actions after they were performed, not the promise. Rainbow had to prove she was worthy of her excitement and showed her devotion to it with a kiss on the tip, her tongue flashing out to run along the rim of Fluttershy’s urethra.
Fluttershy shifted a little, spreading her legs more to let Rainbow get in closer. In turn, the slave showed her thanks by crawling forward, one hand pulling her while the other kept her mistress’s cock close. Rainbow’s mouth stayed wide open, her tongue dragging along the bulging mass of nerves as she moved. Meanwhile, what she passed was pressed against Rainbow’s body, teased by the missing sensation of fur and muscle due to the hot, sticky shirt that still clung to the athlete’s body.
“Shirt. Off.”
Rainbow nodded, digging her face underneath her mistress’s shaft for a moment. Her breath was hot and moist, just like the trapped place of flesh, sweat, and hair. She was so close to the large, full balls that held her eventual prize and Rainbow wanted nothing more than to suck on them. To be degraded into cleaning every inch of what the hot day would have left on her mistress. She knew better though than to avoid her owner’s orders. Besides, she was already more than drunk on the musk and sweat she had gotten already.
Rainbow slowly peeled the clingy fabric from her chest, blushing slightly as the fact that she was without a bra showed itself. Not that she needed much of one with her small tits, at least by comparison to most of the mares she knew, and especially her mistress, but it was a new term on her life. No undergarments, lest she not be available for her mistress. Instead, her handfuls of nerves were always present, with nipples that could cut glass right now that stayed over a smooth six pack that was outlined by her own sweat.
Fluttershy never once looked. Rainbow almost came.
The enslaved mare dropped down, her hands caressing the sides of the now somewhat stiff rod of meat that she wanted so much. She was barely able to swallow fast enough to keep up with the amount of saliva she was producing and her tight, little ass shook back in forth in excitement. “Mistress, may this filthy whore please enjoy her meal?”
Fluttershy tapped the top of her book once. Rainbow stiffened, a faux terror filling her as she thought it would stay at that. Stay at a no. The tightening muscles were contrasted by the long rivulets of arousal that ran down her thighs and the winking and convulsing her pussy was doing in response to its desires. She needed this, but being told no was almost going to be as good as being told yes. Almost.
Fluttershy finally looked away from her homework though as she let out a long breath. “Gilda was an extra cunt today. You may be greedy if I get to be.”
Rainbow almost tore holes in the bedsheet as she was told the news. She knew what them both being greedy meant and it didn’t surprise her that those were the terms. Fluttershy was always the kindest mare that she knew and for her to reward her like that because of her friend being an ass… “Thank you, mistress. I only hope I can take it.”
“You will. I’ll make sure of it.”
Rainbow let out a whimper as she wished she could just move on to Fluttershy’s greed, but she knew better than to even suggest it. She had still failed to perform her duty after all. So, with nothing more needing to be worked out, the slave opened her mouth as wide as she could and pulled herself forward so as to take in her mistress’s tip. The taste from before was never anything like getting to feel it almost breaking her jaw as she ran her tongue across the tip, swirling it in a practiced motion formed over the past few months. It got the exact same reaction from her mistress it always did as Fluttershy let out a small moan.
Rainbow didn’t want a small moan though. Not when it was partially her fault that Fluttershy was so pent up today. So, now that she had some of the cock in her throat, she straightened herself out flat, gripped the bed, and pulled herself forward in one, desperate lunge.
The squeak that came from Fluttershy was an adorable break from her confidence as her hands left her homework, even tossing the book she’d been working with to the side, and gripping the sides of the bed. She let out a gasp as she tried to catch her breath, her body shaking as her thick, throbbing cock grew inside of Rainbow’s mouth. She could hear the familiar choking sounds from her friend as the athlete’s throat spasmed and shook from the trauma. She also knew how much Rainbow loved choking on her, something she acknowledged as she got control back and slammed a hand onto the back of her friend’s head and kept her right where she was.
Rainbow managed the smallest breath through her nose before she was pulled back into her mistress’s soft hips. Whereas Rainbow could kill a stallion by how strong her thighs were, Fluttershy threatened that same fate by how soft and fat hers were as the thick flesh squeezed her head. Not that it stopped her, not when she had ways to warn Flutters that the two were going too far and she was enjoying herself all too much. The smell, the taste, the sensations… They were heaven to her, just as they always had been.
And then, that heaven was removed as Fluttershy pulled her friend off of her cock. It was the last thing the shy pegasus could manage before she collapsed, panting while her hair covered her face. Her cock now stood erect between the two of them as Rainbow coughed a few times to get her throat back under control. The slave then paused, staring at her mistress before extending a hand towards the rod that controlled her so easily.
She was a centimeter away when Fluttershy barked, “Stop.” She was staring at Rainbow from between the strands of her hair, her breath still coming out in pants that left her large, heavy breasts heaving on her chest. She pushed herself up, obviously making sure to swing her chest to tease her slave before she swept one hand through her hair. “On your knees. I need your ass.”
Rainbow shook for a moment, biting her lip as she nodded. She then moved swiftly, not wanting to keep her mistress waiting for another second as she got onto her hands and knees, sticking her ass out as high as she could. Her ass was still small and tight, never having been properly trained for what was coming, just like how both of them liked it.
Not that Fluttershy immediately acted on that fact as her large, flared tip pressed first against Rainbow’s pussy, drenching the tip in her slave’s juices while the latter let out a long, ecstatic moan. The shy pegasus’s hand was gentler, squeezing Rainbow’s ass as she whispered, “How much of a masochist are you feeling today?”
Rainbow looked back at her, grinning like some insane idiot with a death wish before she said, “Mistress, I have a flight exam tomorrow. I want you to make it so I might have a chance to fail it for once.”
It was Fluttershy’s turn to bite her lip before she lifted herself up slightly more, letting the tip of her cock slide from her friend’s pussy straight onto her asshole. At this angle she would swear her cock was a third of the width of her friend’s waist, something Fluttershy very much so couldn’t claim was the same for her own hips, and even when she used both of her hands to stretch Rainbow out it looked like it needed to be twice the width to fit her. Not that she believed that, not after past experiments, but it was enough to make her pause.
Then she remembered Gilda’s teasing for the fact that she was so endowed in every way, in front of so many people, and she shut her eyes as she squeezed her slave’s ass tight and thrust forward.
Rainbow let out a very real yell of pain as she was pushed into the bed, the mattress muffling it as the mare slapped the bedspread frantically, letting Fluttershy know she had gone a little too hard. This was always a little problematic for their agreement because the slapping didn’t mean stop. No, it meant to calm down a little, so it was up to Fluttershy to figure out where that medium ground. This was made even harder by just how tight Rainbow was wrapped around her cock. She could feel every muscle in Rainbow’s ass as it tried to make room for her and her dominant lust begged for her to just keep going. To let the frustration of normally being meek out.
She pulled out a bit though, breathing heavily as sweat dripped from her face, before she reached forward with one hand. After all, Fluttershy wasn’t a strong mare and she was already losing strength in her hips. She needed some sort of leverage. Two hands on the ass was too much though. One gripping Rainbow’s bright, multi-colored mane though? Well, the next thrust got a scream of ecstasy out of Rainbow, so she was pretty sure it was successful.
Rainbow could barely think though due to it. Not only was her entire body shaking desperately, both in an attempt to get free from the painful, all too large object in her ass, but also from the cascading waves of pleasure that were bringing with them multiple levels of orgasms with each movement her mistress made. After all, Rainbow had agreed to this. She had even looked forward to this, and the only real downside she could find was that she couldn’t keep her voice down with how Fluttershy pulled on her hair like this.
Not that that was a high priority as their flesh slapped against each other, pulling them closer as both of their bodies begged more and more for the other. Rainbow could feel every part of the act. Her ass clenched tight enough to make diamonds. Her pussy’s uncontrollable bursts of fluid from the domination. The ever increasing spasms of her mistress’s cock as more and more of it filled her. The pants against her back where Fluttershy’s head laid, her strength having left her ability to even stay properly upright. In any other scenario, Rainbow would have laughed at the fact that all that was keeping the pegasus up was her cock. Right now she couldn’t even manage the air for an attempt though.
No, instead, her air was entirely spent on a final howl as they both collapsed from Fluttershy’s last thrust. It was another day where Fluttershy didn’t make it balls deep inside of Rainbow’s ass, but neither minded. This was enough as the thick cock became stiff as a board, not even letting Rainbow fall properly as it bulged out of her stomach, a problem that grew larger as she dumped her hot, thick seed in. More and more Rainbow’s stomach expanded, until it looked like she was practically pregnant from anal sex, something she would definitely need to laugh about later.
Fluttershy didn’t let her keep the cum inside of her though. Instead, the pegasus put her hands on her slave’s stomach and pushed down, using the cum’s pressure to help pop her cock out, right before the thick, white goo gushed like a geyser against both of theirs hips and waists, ruining the sheet they were on as they laid in a pool of seed.
It was convenient though as Fluttershy pulled her friend in close, her breasts pressing gently against her lover’s back as she whispered, “Are you going to be okay?”
Rainbow smirked for a moment as she reached up and let out a horse, “Babe, you know I can take it. I’m more worried about whatever it was that Gilda did to you.”
Fluttershy hummed happily, more than she had during any of the sex as she nuzzled into Rainbow’s neck and breathed, “Can… Can we talk about that later? I just want to cuddle right now.”
Rainbow laid her hands on Fluttershy’s as she leaned back slightly, just enough to give some pressure back on her lover to let her know she was trying. She wasn’t always the best at this stuff after all. “Okay, but you’re massaging my ass for that first thrust, got it?”
Fluttershy giggled a little. “And some honey tea for your throat. I don’t want you getting too sore.”
“I don’t know. A lot of guys would love it if I shut up.”
To which they both giggled, holding each other tight as they rested, all too happy to have the other to help them face the world.
