Note. To the best of my knowledge this is not based on any existing Fallout Equestria storyline, nor does it follow any particular plot in Fallout 4. This is just the narrative that popped into my head as I was drawing.
 
Maud Pie hitched her cargo shorts and panties up having just finished a much postponed nature call. Unfortunately for the last few hours she along with her two of her other sisters had been more preoccupied with shaking off a particularly tenacious band of raiders that had been pursuing them.  

 
 
Only with the late arrival of the final Pie sister had they been able to pause and catch their breath. That and make visits to the little filly’s room. Even if that just meant going behind a pile rubble.
 
Maud had wandered off a ways to take care of her business. She’d just finished buckling her shotshell belt and pistol holster on and was picking up the folding shovel she’d used to bury her business when she heard a couple giggles. Not cute, infectious giggles like Pinkie had, but sleazy, creepy giggles.
 
Glancing over toward the source of the sounds the earth pony watched a couple of very feral looking stallions emerge from behind the bullet riddled carcass of a former automobile. They both had a crudely made revolvers pointed at her. Maud’s eyes glanced over to her pump action shotgun about 8ft away. Her left hand held the folding shovel.
 
One of the stallions noticed her gaze. “Ah! Ah! Heh, heh! Dontcha think about it! Heh, heh dontcha worry sweetie. We just wanna have some fun. Ya like fun dontcha?”
 
“Yeah I like fun.” The mare said while keeping her usual bland expression. “After all I’m a performer.”
 
The other stallion spoke up. “Oh, oh! Yer a perfermer. Heh! What kinda perfermer are ya? We really like certain kinds of perfermers.”
 
The stallions came to a stop about 10ft away from her. If Maud was to hazard a guess neither of them was more than 20 years old. They might’ve been raiders but if they were they way down in the pecking order. Casually she started to let her right hand drift down toward the .357 revolver on her belt, but the first stallion raised his revolver and leveled it at her face.
 
“Ah! Ah! Dontcha go en do that! Remember we just want ta have some fun. Ya got a pretty face and it would be a shame ta mess it up with a bullet. Heh! Ain’t that right? Of course it is. Now ya say ya were a performer. What kind or performer? Heh!”
 
“Well.” She said with her monotone voice. “I perform with my partner.”
 
“Ya have a friend! Where?” The second stallion was now quickly scanning the rubble. “Where’s yer friend?!”
 
Maud was now holding both of her hands up. Her right one was empty, but her left still held the folding shovel. She addressed the second stallion directly. “He’s here right now. He’s with me even as we speak.”  
The first stallion squinted at the mare. “Show us yer friend right now.”
 
The violet maned mare slowly nodded her head. Then her right hand slowly went and pushed down into her cleavage. This got both of the stallions attention. After a second or so of rummaging Maud slowly removed her hand. In the palm of her right hand was a small, rounded stone.
 
“This is Boulder. Boulder say hello to our visitors.”
 
“What the fuck are ya talking abeut?” The second stallion said. “That’s just a damn rock!”
 
Maud pursed her lips. “You should apologize to Boulder for saying that. Boulder is a magic stone. He can do all kinds of tricks. He can fly. Would you like to see him fly?”
 
The second stallion appeared to be suddenly pondering the age old warning about sticking your dick into crazy, but the first stallion just snorted in disbelief. “Heh! Yeah right. Magic stone that can fly. Okay babe make yer magic stone fly!”
 
Maud nodded her head. “No problem. Watch carefully.” Then with an open palm she tossed Boulder straight up in the air. For just a moment the gaze of both stallions followed Boulder upward.
 
Among improvised weapons the folding shovel, especially if it has sharpened edges, is particular fearsome. Stepping forward Maud grabbed the shovel with both hands and swung it at first stallions throat with all her might. The sharpened tool ripped through his trachea and severed numerous blood vessels in one stroke. He toppled to the ground in crimson fountain of his own blood.
 
The second stallion leaped back in surprise and promptly lost his footing and toppled to the ground on his back. He was about to scream when Maud violently rammed the point of the entrenching tool into his mouth. The steel spade head cleaved his lower jaw clean apart and continued on to severe his spine at the base of the skull. His body went limp almost instantly.
 
Maud wrenched the folding shovel out of the dead stallion’s mouth. Then she looked down at her two fallen foes. Quickly she wiped the blood off the entrenching tool on their bodies. Looking around for a moment she eventually found Boulder and returned him to his home in her cleavage. Then picked her shotgun and headed back to her waiting sisters.
 
Pinkie was entertaining her sisters with some silly tale when Maud came walking up. Limestone glared at her. “Sun and moon Maud! How big of a shit did ya have to take? I swear we were about to go looking for you.”
 
Maud pushed the loading gate open on her shotgun and inserted one more 12ga shell into the tubular magazine. With that accomplished she glance over at Limestone. “Sorry I was late, but Boulder and I had to put on a little show.”
