Lunchtime at Canterlot High, home of a suspiciously high bimbo:plain jane ratio. The dining hall is abuzz with activity as students prepare for the last leg of their day. In one corner, three members of the Rainbooms cluster together; one far more distraught than her friends.

“Oh man, I am so boned,” Rainbow Dash sighs, letting her forehead drop against the cafeteria table. The dull thud and sour mood does nothing to damper the cheery grin of Pinkie Pie, who bounces over to her and slings her arms around the sporty girl’s neck.

“Omigosh, congratulations Dashie; I knew you could do it!” she squeals, thrusting Rainbow’s face into her cleavage and wiggling about. After a moment, she gasps and tightens her grip, a smile splitting her face in half as she somehow ramps up the exuberance to another level. “We totes have to throw you a ‘So Boned’ celebration party, with a penis cake! Do you want vanilla, chocolate, or strawberry?”

Sputtering, Rainbow finally pulls away from her over-eager friend and responds with a small growl, “No Pinkie, I mean that I’m going to be screwed.”

“Well that’s silly,” the frizzy-haired girl giggles, “Who ever heard of a carpenter-themed party. Ooh! Unless you want to be drilled, because I can totally arrange that too!”

With a heavy sigh, Applejack reaches out and places a hand on the bouncy girl’s shoulder. Pinkie pauses, glancing back at her blonde friend and raises an eyebrow as she drawls out, “I think what Rainbow means is that she’s in a bit of a pinch.” Pinkie blinks, and Applejack tries again.

“A tight spot?”

Still nothing.

“Outta luck?”

“Psh,” Pinkie waves her hand and laughs. “Puh-leeze, Dashie can never run out of luck!” For emphasis, she reaches around her friend and cups her breasts. Rainbow grits her teeth and gives a quiet whimper as the girl juggles her jubblies. “Just because they’re not as big as yours AJ doesn’t mean her man-catchers are any less enticing.”

“An exam, sugarcube,” AJ finally groans, snapping her fingers even as Pinkie opens her mouth, “and it ain’t an oral one.”

The jovial girl deflates a little, pouting cutely and crossing her arms under her chest. Her breasts jiggle at the contact, and before long the frizzy female is shifting her forearms back and forth to make them bounce, a smile on her lips again. With a sigh, Rainbow turns away from Pinkie and, adjusting her shirt, seeks comfort in her less air-headed friend.

“I just don’t get math, AJ,” Rainbow groans. “It doesn’t make any sense to me. How’d you get ready for it?”

“I didn’t.”

“WHAT? But the test is, like, tomorrow!”

“I reckon so,” the blonde chuckles, thrusting her chest up and out, “but I’m not gonna be in there tomorrow; too much work to do on the farm.”

“So you’re doing a make-up then?”

AJ rolls her eyes and chuckles, “C’mon now, sugarcube, I’m as liable to miss a make-up as I am a regular exam.”

“Then, how did…” Rainbow’s eyes widen as her friend lays a hand on her enormous thighs, watching the muscular limbs jiggle ever so slightly.

“A man’ll do just about anything to get his head squeezed between a good pair of legs. We agreed that the work I’d done so far was good enough to warrant a passing grade.” A slow smile spreads across AJ’s lips as she leans in closer, “And then I rode his face for a dadgummed hour.”

Dash gulps, her mouth dropping a little as the blonde chuckles and leans back into her seat. “Y-you slut!”

“Guilty,” she laughs again, raising her hand. “But I also got business to take care of, so you’ll forgive me if I don’t much mind the name calling.”

“Oh, are we sharing pet names? My favorite’s Honey Bunny.” a forth voice chimes in.

The girls turn to regard the insanely endowed member of their group, Fluttershy. The pink haired girl gives an awkward smile and sits down beside AJ, every small motion sending ripples through her head sized breasts. “I guess not. What did I miss?”

“Dashie’s boned and Applejack’s grading teachers on a curve,” Pinkie giggles.

“Oh, congratulations!” Fluttershy smiles as she reaches out and grabs Rainbow’s calloused hands, holding them in her own. “I knew you could do it, Rainbow, you just had to put your mind to it!”

“Why does everyone think I need help with my sex life?” Dash whines, pulling her hands away and scowling again. “I’ll have you know, I’ve been very satisfied this quarter; that’s part of the problem. I’ve been so insistent on getting laid and practice that I’ve completely forgotten to study!”

“Ooh…” Pinkie and Fluttershy say together while Applejack just shakes her head and laughs again. Rainbow sighs, letting her head thud back against the table once more.

“Like I said, I’m done; unless you think I could sleep with the teacher too?” shooting a hopeful glance to Applejack, she flinches as the blonde crosses her arms and shakes her head. “Yeah, that’d be pretty low to take some of your leverage. Guess I’ll have to get used to blowing delinquents behind the gym in preparation for summer school, cuz that’s all I’m going to have around me…”

As Dash sinks deeper into her funk, the three girls glance between one another. None of them seem to be able to come up with a solution, though hardly surprising considering the company. AJ while wily and clever, just isn’t interested in book learning. Pinkie can’t keep her attention focused for any extended length of time, and has gone back to poking her chest. And Fluttershy… while she may have had breasts the size of her head, she was more boob than brain. And yet, a thought seems to slowly slide its way across her mind. After a long moment, she speaks.

“Well…” the usually quiet airhead starts, biting her lip at the rather angry glare she gets from Rainbow, but continues on anyway, “you could always try asking Twilight for help.”

After a moment of silence, Rainbow grins and pulls out her phone, “Hey yeah, Twi’s all about helping those in need. Good idea, Fluttershy.”

While Dash ticks away at her phone, the shy girl beams and wriggles in her seat. The message is sent, and Rainbow returns with a smile on her face. Fluttershy stares at her intently for several seconds before clearing her throat.

“Um, sorry,” she mutters, “but could you…?”

“Huh? Oh, yeah. Fluttershy, touch yourself.”

The busty bimbo gives a submissive squeal of delight, her fingers sliding up under her skirt and rubbing herself with a slow, easy rhythm. Dash shakes her head, but it’s only a few seconds later when the phone chimes. Grabbing it from the table, she reads over the message and grins.

“Alright, Twilight says she’s up for a cram session at her house, tonight!”

“A cram session!” Pinkie gasps, clapping her hands to her cheeks. “That sounds like so much fun!”

“Right? Just what I need to take the edge off!”

---

That night, Rainbow finds herself scowling at Twilight. The purple haired girl has notes and open textbooks scattered about her room, a broad smile resting on her lips. After a moment, Dash sighs and rubs at the back of her neck.

“So, when you said cram session, you meant…”

“An opportunity for us to go over all material discussed in class thus far,” Twilight says with an excited bounce, “we get to stay up all night, studying!”

“So, a cram session isn’t…”

“Seeing how many dicks you can take at once? No, of course not.”

Crossing her arms, Rainbow scowls and glares at the ground. “Well that’s dumb; you got me all excited for nothing.”

“Oh Dash,” Twilight sighs, walking over and draping her arms lazily over her friend’s shoulders. They stand front to front, their breasts squished together as the nerdy girl smiles. “The last thing you need right now is to worry about getting laid.”

“It’d make me feel less tense,” she huffs, even as Twilight takes her hand and pulls her over to the bed. Laying her down, the athletic bimbo stiffens as she feels her friend’s hands under her shirt.

“I can help you relax,” Twilight promises, whispering in Dash’s ear. “But first you have to get some studying done, okay?”

“Y-yuh,” Rainbow gulps, nodding her head. With a happy sound, Twilight removes her hands and begins going over the lessons from the beginning. To her credit, Dash makes it a whole two hours before grabbing her hair. With a howl, she thrashes about on the bed.

“I. Can’t. TAKE IT!” she moans, kicking her legs in the air. “This egghead stuff is the worst!”

“But you’re doing so well! Come on, just a little bit more and I’ll let you take a break. We can even-”

As Twilight reaches out to touch her, Rainbow swats her hand away and scowls.

“No. Look, I appreciate the effort Twi, but lezzing out is totally not what I need right now. I need a dick, and I need it fast.”

The purple haired girl opens her mouth to respond when the door to her bedroom gives a gentle creak. Both girls look up and see the familiar face of Shining Armor smiling in at them.

“Hey gals, everything okay?”

“Peachy!” Twilight says with a nervous laugh, not missing the rather hungry look her friend is currently shooting her brother. “Just a little, pre-exam stress is all!”

“Well, all right. Let me know if you two need anything.”

The door closes and Twilight whirls on her friend. “No, not happening.”

“Twi, come on! I need a good lay and you’ve got an older brother not two rooms away.”

“He’s got a girlfriend!”

“I’ve seen his girlfriend,” Dash grins, “You could tell her to go dry off in a lake and she’d come through on the other side without a bit of water on her.”

“Cadence is not stupid!”

“I didn’t mean stupid, stupid, I meant gullible!”

With a huff, Twilight narrows her eyes and shakes her head. “Either way, my brother is not a piece of meat.”

“No, he’s a beef-cake,” the horny girl sighs, dragging her ‘e’s. After a moment of staring off into space, Rainbow gets to her feet. “Just a quickie.”

“Dash!” the nerdy bimbo glares as best she can as she gets to her feet. “I’ll stop you if I have to.”

The sporty girl pauses and then turns back to her friend with a smug grin on her lips. Stepping back to the bed, she puts her hands on her hips and thrusts her chest out into Twilight’s. The smaller bimbo stumbles, landing back on the bed, her soft backside stinging a little at the crash.

“You, are gonna stop me? No offense Twilight, but you’re out of your depth with me. It’s just for a little bit anyway, I’ll be back.”

Slightly cowed by her curvier friend, Twilight tucks her hair behind her ear and sighs. “Okay, but just for a little while, and if he says no then you come right back!”

“Sweet,” Dash grins and plants a kiss on her friend’s forehead before hurrying down the hallway to Shining Armor’s room. Twilight strains her ears to hear the inevitable rejection as the door opens, but the mumbled conversation is too quiet. However, she gets her answer soon enough in the form of a deep moan.

“Oh, WOW!”

Color rushes to the brainy bimbo’s face as Rainbow’s ecstatic voice reaches her ears. It’s quickly followed by the quiet, obnoxious squeaking and thudding of a busy bed. Gulping, Twilight turns back to her notes and begins studying them again.

It doesn’t take long for her to block out the noise entirely; after all, it’s not like this doesn’t happen with Cadence and Shining Armor either. Highlighter in hand, Twilight focuses on the page in front of her, ignoring the squeaks, whimpers and cries coming from her brother’s room. Not paying an attention at all. Nope. Not a bit.

“Oh, oh jeez, keep going!”

“You like that?”

“You’re ruining my legs! I’ll nev-never be able to run again at this rate!”

“That’s the idea; I get to keep you to myself.”

“Oh, god that’s hot! More, more!”

N-not paying attention at all, Twilight thinks, even as she pumps the luminescent yellow pen in and out of her lips. She’s definitely not thinking of watching her friend get railed by her brother, and definitely, definitely not thinking of trying to join in!

As Rainbow’s cries reach a fevered pitch however, Twilight finally grabs her notes and hurries to her brother’s room. Throwing open the door, she snaps, “Shining!”

Brother dearest glances up, already balls deep, doggy-style in the sporty girl who’s buried her face in the sheets. Rainbow gives a plaintive moan as Shining grins.

“Oh, hey Twily! Sorry about the ruckus.”

Gulping, the nerdy bimbo steps forward and scowls. “You, you jerk! How could you?” Whimpering, she slides a finger between her legs and bites her lip, trying not to tear up. “How could you forget about me?”

Shining Armor laughs, even as Rainbow peeks up from between the sheets. “Hey, don’t believe those crocodile tears,” she warns, “Twilight’s all about studying, we’ve got an exam tomorrow and she was telling me I shouldn’t come to see you to work off any steam.”

Her brother frowns at that, a look that sends a shiver of dread down the usually clever girl’s spine.

“Really?”

“W-well I was just thinking that, maybe it would be best to study together, and not bother you, beca-” the halting ramblings of Twilight are quickly stopped by Shining raising his hand and shaking his head.

“Twily, you know I said that I’d help you guys with anything. So why don’t you sit down over there and start reading the notes out loud. Then, once Rainbow’s tired out, you can switch places?”

“You mean it?” Twilight squeals, practically gushing with excitement. Her brother nods and the perked up bimbo pulls up a seat, clearing her throat and starting from the beginning.

Her words are mostly drowned out by the delighted cries and dirty talking of Rainbow and her brother, but as she strokes herself with her free hand, Twilight smiles to herself. Soon, the tables will be turned, and she’ll be the one getting railed…



“Wow, thanks Twilight!” Rainbow laughs, thrusting her hands into the air. “That cram session really helped last night. Even though I’ll probably sleep for a day, and walk funny for a week, I don’t think I could have done it without you.”

“Y-you guys went all night,” the purple haired bimbo whimpers, holding her hands behind her back. “I didn’t even get to get laid once…”

“Aw, c’mon. It was still a lot of fun, and we both did well on the exam, right?”

“My hand cramped up in the middle because I was fingering myself all night.”

“Ouch, that really stinks. Well, thanks anyway,” Rainbow grins, “Twily.”

The girl in question whimpers again and shakes her head. “I-I gotta get some dick in me… like, now.”

Slinging an arm around her shoulders, Rainbow grins. “That, I can help you with. Let’s go.”

Favors are meant to be repaid after all.
