The Crusaders Have A Tumble And A Fumble With Rumble
It had been a very active day for Rumble, the young colt and future Wonderbolt. Having begun a revolution of Blank Flanks against the 'tyranny' of those with Cutie Marks, he'd finally reached the inescapable conclusion after spending an afternoon cooking with his big brother Thunderlane that it was actually possible to have a special symbol and enjoy other activities too. He was wrong, the Crusaders were right, and everything had now been peacefully settled.
Humming the lyrics to a catchy little song he'd composed all by himself earlier that day (although, the lyrics about the advantages of having an imageless rear no longer meant anything to him) he was just gathering up his stuff in the Crusader's clubhouse before departing with Thunderlane when he heard the door behind him creak slightly, before slamming shut at quite a high volume.
Wondering who'd entered the room, Rumble looked up in surprise to see no other than Scootaloo, Sweetie Belle and Apple Bloom there, all wearing big smiles on their faces and staring at him in an odd way, which made him feel kind of nervous. Trying to remain calm despite his sudden anxiety (why should a tough colt like him be scared of a bunch of girls after all) he approached them tentatively, offering them a small greeting as he attempted to pass by.
"L-Listen Crusaders..." He started, biting the bottom part of his lip. "I can't thank you enough for today. I now realise that I'm not being 'put in a box' at all by getting a Cutie Mark, and I was wrong to steal the members of your camp the way I did. I can still try to fly like my big brother, but I can also do other fun stuff I like too. W-Well, goodbye..."
Stepping over to the front door, Rumble was most surprised to find his path suddenly blocked by his fellow pegasus Scootaloo, who'd stepped out of sync with the other two fillies. Taken aback by this sudden manoeuvre, Rumble was in no position to resist as Apple Bloom went to push him to the back wall, and Sweetie Belle's horn light up to hold him in place there.
"W-What's going on?!" Rumble understandably felt very nervous now, as he struggled without success to free himself from the little unicorn's powerful aura. "W-Whatever you're going to do with me, it won't work. M-My big brother is outside, and if I start screaming..."
"Actually, no he isn't." Scootaloo spoke for the first time, a mischievous glint playing in her eyes. "We sent him on his way, and told him we'd get you home safe. After all we're such trusted fillies, respected the town over for helping others with their destinies, why wouldn't he believe us?!"
" Also, if anypony's gonna be doing any 'screaming' 'round here, I'm kinda hope it's gonna be us." Apple Bloom added cryptically, rubbing her hooves together in an excited manner. "Now, you just make yourself nice and comfortable, Rumble. This shouldn't take long at all..."
"The fact is Rumble, we thought about what you said earlier and you sort of had a point..." Sweetie managed to speak, even as her powerful magic kept the young prisoner firmly at bay. "We don't do very much now besides help others get their special marks, but maybe it's time we changed that. And we were kind of hoping you could help us out there..."
Rumble wondered what on Equestria she could mean by that: well, he was about to find out. No sooner had the last Crusader finished speaking, he found himself flipped over onto his belly, and all three Crusaders trot over to inspect that general area thoroughly, paying special attention to his rather diminutive genitalia.
"Hmm, it's nowhere near as huge as mah brother's..." Apple Bloom prodded the small organ with disappointment, as if she was expecting something bigger and better down there. "...But ah guess it'll have to do. Anything larger, and it probably wouldn't fit into my hole. Now, who wants to go first?!"
"Oh me! I do! I do!" Sweetie Belle put her hoof up, as she curiously knocked around Rumble's balls as if she was playing a nice game of marbles. "I'm the one who picked the perfect time and place to ambush the victim, after all. Come on girls, you never let me have any fun!"
"Hey wait just a second!" Now it was Scootaloo's turn to voice her objections, and seeing as Rumble's penis and testicles were fully occupied by her randy friends, she had no choice but to resort to licking his butt. "I was the pony who thought of the plan, and don't discount Apple Bloom's claim, either! After all, she is sort of our leader. Now, how are we going to resolve this..."
The trio of underage sex offenders pondered this very subject for a good few minutes, during which time Apple Bloom took the opportunity to jack Rumble off, Sweetie Belle began suckling intensely on his scrotum area and Scootaloo just couldn't keep her tongue away from the colt's anus. It sort of tasted like tangy straw, and was surprisingly addictive.
Ignoring Rumble's pathetic, fruitless struggles, Apple Bloom was the first to break the deadlock. "Ah know! Let's play cock, raper and scissors position... oops, I mean rock, paper and scissors! C'mon, we all know the rules, so let's get started. The winner gets to have her way with him first, the loser has to clean up and take the heat if anything goes wrong. On your marks, get set... go!!"
In a variety of rounds too boring to describe here, it was the ultra-competitive Scootaloo who emerged victorious, with Sweetie Belle left with sloppy seconds after her two friends were done ("Why is it always me"?! she was heard to wail). Without further ado, and before any of the grown-ups could start getting suspicious, the orange pegasus moved forward to straddle the panicking Rumble, a big eager grin decorating her face from ear to ear.
"That was a tasty appetiser, now it's time for the main course!" She remarked, while licking her mouth clean and yanking down Rumble's foreskin to shove his cock inside her vagina. "Come on, 'future wonderbolt'! Let me touch the clouds above, and as Rainbow Dash always tells me: no slacking! Now, move it!"
Rumble tried, he really did. But faced with the energetic Scootaloo bouncing on top of him like a trampoline and her tongue caressing his muzzle in the sexiest way imaginable (though the last thing he wanted to do was taste his own shit) he had no choice but to release his special milk formula. It cascaded from the tip of his phallus into the heart of Scootaloo's womb, a few moments later being replaced by the filly's labia bursting which left a stream of blood dripping from her groin area.
Sweetie Belle was prepared for such an eventuality though, and quickly cleaned up the mess as an exhausted Scootaloo hopped off and Apple Bloom had her turn. Unlike her orange companion, she preferred to let her strong fruit bucking legs do the talking. Ho, diggety! Rumble was relentlessly kicked and stamped on until his resistance finally gave way, and once more his creamy goodness ended up deep inside one of the fillies, accompanied by a burst of haemoglobin.
Realising with a pronounced sigh that the hut would now need plenty new paper towels, Sweetie Belle's frustration was sated by the fact it was now her turn to abuse their unwilling captive. Unlike her friends though, the little unicorn had no intention of falling pregnant at such a young age to possibly ruin her burgeoning music career, and she was sick of the sight of blood, anyway, So, she simply shoved her horn up Rumble's poophole, and to the accompaniment of some satisfied howls and growls of agony was able to gain plenty of sick pleasure from this nefarious activity alone, as well as potentially ruin Rumble's chance of ever having a non-painful crap again.
With all three fillies finally having had their fill of illicit, illegal sexual exploits, they finally released an obviously traumatised Rumble from their demonic spell... but why did he have a big smile on his face?
"Huh, I thought for certain he'd be pretty darn upset after what we did to him..." Apple Bloom remarked, scratching the back of her head. "Oh well. As long as he's happy, he won't snitch on us and it won't cost him a bit in future therapy bills. Everypony wins, I guess."
"Yes, and finally we know what we've been 'missing' out on whenever my big sister has a certain visitor late at night!" Sweetie Belle remarked in triumph, as she thought with annoyance about the strange sounds emitting from Rarity's room whenever Fancy Pants popped over for an 'innocent' random sleepover. "... She no longer has any leverage over me! I can finally say to her face: 'I've done everything you have'..."
"Wait, what is that...?!" Scootaloo, having been the first to finish her little romp, was slightly more clear-headed than her cutie compadres, and pointed a quivering hoof at a now glowing Rumble.
The colt himself was far too exhausted and gibbering to pay the slightest bit of attention as to what was going on on his flank, but the others had a very clear view. To their astonishment, once the intense white light had faded, everything was just as it was... with one minor exception.
"Well, blow me down with a feather..." Scootaloo remarked, shaking her head in disbelief.
"Looks like we've done it again." Sweetie Belle seemed pleased with her day's work, and nodded with satisfaction at her colleagues and friends.
"Well, I don't know about you girls..." Apple Bloom commented, while giving off the biggest grin of the day. "But ah say he's earned that, what d'ya all say?!
The glorious event they were all talking about was, of course, Rumble getting his long-undesired Cutie Mark.
It wasn't anything to do with flying.
It wasn't even anything to do with cooking.
It was instead a giant grey dick being shoved into a eager mare's mouth.
Yes, well earned indeed.
