Shy

Flashback, about 30 minutes earlier

"Come on girl, show me what you got."

Laying on the couch was a large, muscular truck driver appropriately named Big Rig. His muscles bulged from his daily weightlifting that didn't benefit his job very much, but it did help him find his new girlfriend.

Big Rig was laying on his back, fully unclothed, with his girlfriend of several months on top of him. They had started having sex a few moments ago and were ready to finish for the night. The large man's cock was deeply inside Fluttershy, who was bouncing up and down on the large pole of a muscle.

"Oh god, you're so big... this feels incredible!"

"I bet you wish your wife could do this! Oh fuck, I'm almost done."

"Hurry up and finish before your kid walks in!"

"Here it is!"

And with that, Big Rig ejaculated strongly deep inside his girlfriend. Fluttershy felt the warm and sticky fluid rush around inside of her, mixing with her own fluids as her boyfriend finished. They were both panting very loudly, and slowly Fluttershy lifted herself off of the large cock that was starting to soften. She got off the couch and bent over to pick up her underwear, putting them on as her boyfriend did the same thing.

"That was amazing!" Fluttershy said, "You must tell me how you got your cock to grow so big."

"I told ya, it's all my dads fault," Big Rig said, as he smirked and looked at his girlfriend.

The two had been together for a few months now. They had met when Fluttershy and Rainbow Dash wet out drinking one night and Rainbow Dash had to leave early to take Scootaloo home from one of her friend's birthday parties. Fluttershy stayed behind, and ended up going home with one of the men who was obviously looking for sex. He and Fluttershy had been talking for a while after Dash left and when Fluttershy told him that her wife had left, he offered to walk her home. Fluttershy, naturally, told him he didn't have to, but Big Rig insisted.

When the two got outside, Big Rig suggested that he drive her home. Most people in the city had cars, but they only used them for traveling, and walked most places within the town. But Big Rig, being a truck driver, always drove everywhere.

Fluttershy jokingly asked if he was going to drive her home in his truck, and he laughed and just used his own car, since taking a company vehicle around town would certainly get him fired.

Soon after Big Rig started driving Fluttershy to her house, he stopped and looked at her and said they should go back to his house instead. Fluttershy instinctively questioned it, but after a while she agreed and they drove to the house of the large truck driver. That night they had gone in and had sex, and Fluttershy, afraid that if Rainbow Dash saw her come home in the car of someone she met at the bar, her wife would suspect her, walked all the way home from across the town, arriving at their house at 3 in the morning.

When Rainbow Dash asked her why she came home so late, Fluttershy said that she passed out drunk and was woken up by the bouncer.

The next day, Fluttershy ran into Big Rig while on the way to her veterinary hospital. Fluttershy thought what happened last night was going to be a One time thing, but Big Rig started talking to her and ended up asking her out. Fluttershy immediately reminded the man that she was married and declined, but instead of walking away, Big Rig kept asking her, trying to convince her to say yes, telling her things like "I can be what no woman can" and "your wife doesn't need to know." Eventually, Fluttershy gave in and said yes, and they secretly started dating without Rainbow Dash knowing.

During their severely relationship, Big Rig revealed that he had previously had a wife, and a son, but that she died in a bank robbery while visiting a dangerous city. His son still lived with him, and was named Belt Rig, but had the nickname Manny because of a joke that his parent had made about him being overly masculine.

Over time, the two became more and more attached and had more sex. This consequently made Fluttershy pay less attention to her wife and adoptive child, and her marriage began to slowly fade.

Recently Big Rig had convinced Fluttershy to try to get her wife to move out, so that he could move in with his girlfriend and phase Rainbow Dash out of their lives. This caused a lot of fighting between the wives as Rainbow Dash felt she was being divorced and thrown out. They both became overly protective of their daughter and never felt happy around eachother like they did in their first years of marriage.

Now they were both sitting on the large sofa, bought with Rainbow Dash's money, right after having sex.

"Thank you dad!" Fluttershy exclaimed. "I wish my wife could do that. But she doesn't want to use toys ever because she thinks 'they're impure' and stupid shit like that."

"Speaking of that bitch," said Big Rig, using the same word he always used to describe his girlfriend's wife, "when's she moving out? I'm ready to sleep here and stop having to leave every night cause she's living here instead of me."

"Oh, she should be leaving soon. I'm just waiting for her to file for divorce. And by how she acts, that won't be long."

"Use her alimony to buy a bed that isn't as loud."

"I was right."

Standing there at the entrance to the living room was Fluttershy's wife, Rainbow Dash. She stood in a very natural stance, leaning against the wall with her arms semi-crossed and with one leg propping her body up against the wall. Her mouth was formed into a blank expression, but her eyes were filled with pure rage.

"R-R-Rainbow Dash?" Fluttershy choked out, incredibly shocked from being caught in the act.

"It's, uh, not what it looks like," Big Rig said in combination, a useless attempt to ward off the idea.

"This, is why you came home late that night. This, is why my cash has disappeared. THIS is why you don't pay attention to me anymore. THIS is why you wanted to throw me of. THIS IS WHY YOU HATE ME." Rainbow Dash expressed, letting her full anger out into each word.

"Oh, fuck in getting out of here," Big Rig said to Fluttershy, as he stood up and started to hastily walk towards the other exit.

"OH HELL NO," Rainbow Dash said has she sprinted at the man. She passed by Fluttershy who tried grabbing her wife's leg but wasn't nearly fast enough to stop her. She ran into the kitchen which was where Big Rig was running to, since there was an exit into the small garage in the house.

Rainbow Dash grabbed Big Rig by the neck right after he picked up the pace and started full out running away from her. She put him in a headlock and stared down at him.

"What's the matter, punk?" she started, looking at him with fiery eyes. "Get caught in the act and you're just gonna abandon your wife like that? What kind of a man are you?"

"She's not my wife" he managed to squeeze out as he struggled to remove himself from the headlock, but he wasn't nearly as strong as the elite athlete holding him down.

"She seems to think she is."

"Rainbow Dash!" Fluttershy yelled, as she came stumbling into the kitchen.

"Oh, look, there she is now."

"Please, Rainbow Dash, let him go. It's all my fault! Don't hurt him, he didn't do anything!"

"Let him go? Hah!" Rainbow Dash replied with a cackle. "Let him go? LET HIM LEAVE HERE? WHY THE FUCK SHOULD THIS PUNK BE LET FREE? HE STOLE MY WIFE!" She screamed, tightening her headlock around his neck, starting to strangle him now.

"Please! Stop!" Fluttershy pleaded.

"HE STOLE MY WIFE!" Rainbow Dash said, again tightening her headlock. At the same time she opened up a knife drawer and pulled out the biggest blade inside.

Seeing this, Fluttershy rushed over to Rainbow Dash and grabbed her arm to try and take the knife away. "NO! DON'T!" She yelled.

Fluttershy was met by a kick to the gut which sent her tumbling away onto the floor. She had a very bad bruise on the stomach now. She looked up and saw Rainbow Dash holding the knife up to Big Rigs throat, right above where her other arm was choking him.

"HE COMMITTED ADULTERY! THAT IS PUNISHABLE BY DEATH!"

Rainbow Dash pierced his throat with the knife, and sliced every vein, artery and pipe all the way down to his spine. He started bleeding profusely, blood pouring extremely fast. He bled out in seconds, but the blood was still spilling.

Speechless, Fluttershy ran over to her dead boyfriend, looking at the horrible sight before her.

"Well Fluttershy, look at your husband now! He's not so hot anymore is he?"

Fluttershy began bawling her eyes out, sobbing over the death of her boyfriend of four months.

"Quit crying bitch! You're gonna wake the neighbors! Now get back in the living room!" Rainbow Dash yelled.

Fluttershy couldn't hear her. Her mind completely blocked out all her senses because she was in so much shock. Her boyfriend had just been killed by none other than her wife, who she cheated on.

"What the fuck are you doing? Come over here!" Rainbow Dash commanded her again.

Fluttershy still couldn't hear her. She was still completely paralyzed by shock, and her muscles wouldn't respond to her mind. Her eyes felt very tired from all of her sobbing, and had turned a deep crimson color, on the verge of going bloodshot.

"I said COME ON!"

Rainbow Dash set down the knife on the countertop and grabbed Fluttershy by the back of the collar on her shirt. She yanked extremely hard which caused the front collar to bite into Fluttershy's neck and stretch until it started ripping. She was thrown from Rainbow Dash's pull and fell onto her back, slamming the back of her head on the hard kitchen tiles. She kept sobbing, her vision now blurred so much from tears that she was blinded by them.

"Get up," Rainbow Dash yelled. When Fluttershy proved to be disabled by the shock, Rainbow Dash bent down and grabbed both of the smaller woman's shoulders, then hoisted her up. Fluttershy couldn't stand, and her knees refused to work into an upright position and she dragged her lower legs all over the floor. She was sobbing the entire time.

"STOP CRYING!" Rainbow Dash yelled at her, full of rage. She had been betrayed by the love of her life, the person who vowed inside that wedding Chappell to be by her side forever had gave their relationship a big Fuck you and SHE was the one crying. Rainbow Dash had never felt more angry in her life.

Fluttershy's eyes had started to run out of tears. As such, she was now feeling very tired, exhausted from crying her eyes out. She looked up at the person holding her by the arms, and saw an expression of anger on her face. She knew she had to say something. She stammered out and said, extremely softly, "I-I-I-I'm sorry."

Rainbow Dash looked down at Fluttershy and saw her tear covered face trying to form into an expression of guilt. But she knew that the emotion that the woman below her was trying to put on wasn't felt at all until this very moment. "You're sorry? That's all you have to say?" She asked in response, still full of anger.

"I-I-I-"

"YOU cheated on me! You vowed in that Chappell three years ago you'd love me forever and you do THIS, and all you have to say is that's you're sorry?"

"I-I- I can't believe-" Fluttershy tried choking out. Her mind wasn't taken over by shock anymore, but now by many emotions of extreme guilt, fear, and sorry.

"I can't believe I didn't notice! How the fuck did I not think that you were cheating on me when you told me you wanted to throw me out! Although you probably didn't think twice about it. You probably thought," and she said this in a mocking voice, "'oh I'm just going to cheat on my boneheaded wife, she'll never notice! I'll just throw her out and get married to someone else, that dumbass bitch will never find out.' YOU THOUGHT THAT, DIDN'T YOU."

Fluttershy could barely think now. Her mind was taken over by emotions and they didn't allow her to properly figure out what to say. But she did know one thing- She'd done fucked it up.

"No- no I didn't-"

"YOU DID DIDN'T YOU!"

"Please stop yelling,"

"AND WHY THE FUCK SHOULD I-"

At that moment, the door opened. In the doorframe stepped in Big Rig's son. He looked to be about for years old, and was very short. He did have very large muscles for a boy his age though. He resembled his father in his face and eyes, and his hair was the same as his dads, a deep red color.

"Oh no" Fluttershy said in horror.

"Fluttershy? Where's my daddy?" The child said, completely unaware of what was unfolding.

"Oh, so you had a kid with him too? I didn't know you we're THAT much of a whore." Rainbow Dash said, looking at the kid in question.

"Fluttershy, who is this person?" the child asked again.

Fluttershy looked nervously at Rainbow Dash, who had was staring at the kid with an expression of disgust. Soon she figured out what she was planning on doing.

"Manny, you need to run away. Run, please manny, run. Please." Fluttershy warned.

"Oh fuck no I'm not letting him run," Rainbow Dash said in reply to this. She threw Fluttershy down onto the floor and picked up the knife she used to slice Big Rig's throat. She stomped over to the kid who looked up at her with a blank expression.

"MANNY! RUN! PLEASE RUN! PLEASE MANNY, RUN!" Fluttershy yelled from the kitchen.

The child didn't listen to Fluttershy's warning and just stood there as Rainbow Dash walked over to him, picked him up with her free hand from the top of his head, raised the knife up to his neck, and slashed his throat.

The child bled out before he could scream. He died without a word of fear.

Fluttershy watched Rainbow Dash murder the kid from the kitchen. She screamed as she saw him get his throat cut. "NO! MANNY!"

She got up and sprinted over to the child's dead body, past his murderer who had dropped him on the ground and stood there blankly, knife still in hand. Fluttershy grabbed the corpse and stared in shock again at the knife wound in his throat. Blood covered him from his neck all the way down to his thighs and one touch of his body covered Fluttershy's hands in the red fluid.

"Oh my god, manny, why..."

"You know exactly the fuck why." Rainbow Dash snapped at her. She stood above the smaller woman, and still had an expression of rage.

Rainbow Dash took the knife by the blade in one hand and the handle in the other, then effortlessly snapped it in two with her strength. She chucked the pieces into the kitchen somewhere, whereas she stood in the living room. She then bent over and picked up Fluttershy by her waist and threw her one the couch. They were now alone. Big Rig and his son were both dead, and Fluttershy had no other relationship anymore.

"FUCK YOU, FLUTTERSHY. HOW THE FUCK COULD YOU DO THIS TO ME?" Rainbow Dash screamed in anger, now able to let her emotions out without distraction. "I DID SO MUCH FOR YOU, AND THIS IS HOW YOU THANK ME? BY TRYING TO THROW ME OUT AND CHEAT ON ME? HOW FUCKING DARE YOU!"

"I'm so sorry!" Fluttershy squeaked out in response, crying in reaction from being yelled at.

"REMEMBER WHO GAVE YOU THIS HOUSE? REMEMBER WHO SUPPORTS THIS FAMILY? REMEMBER WHY YOU DON'T NEED TO WORK ANYMORE? THAT'S ALL BECAUSE OF ME! WHY DON'T YOU FUCKING CARE?"

"I do care about you!"

"NO YOU FUCKING DON'T! IF YOU CARED YOU WOULDN'T OF CHEATED ON ME FOR THAT FUCKER WITH THE SLIT THROAT!"

"I'm so sorry! I'm so sorry!"

Rainbow Dash caught her breath, and calmed down. She stopped screaming, and sat down on the couch with Fluttershy. She looked at her with anger, and Fluttershy looked back in fear and guilt.

"When we got married, you said you'd love me forever! What happened to that?"

"I do love you!"

"YOU LIED!" Rainbow Dash yelled, and slapped Fluttershy across the face with the back of her hand, leaving a red mark where her knuckles had impacted. Fluttershy covered up the area immediately with her hands, as it hurt excruciatingly.

"Why'd you lie, you bitch? Why'd you lie in front of five royals? In front of your parents? In front of all of or friends? Why'd you lie directly to my face?"

"I am so sorry for cheating on you-"

"THAT'S NOT WHAT I FUCKING ASKED!" Rainbow Dash yelled again, this time slapping her in the same way but in the chest.

"I think I know why," Rainbow Dash said, "Maybe it's because your parents forgot to beat your ass when you were a kid. Well don't worry Fluttershy, I'll make it up for you."

She then grabbed Fluttershy's shoulder and threw face down onto her lap. She pulled her upwards so that her thighs were directly over her knee. This made Fluttershy gasp when she realized what Rainbow Dash was doing.

Rainbow Dash slapped Fluttershy's rear with her palm as hard as she could, which left a deep black mark on her skin. Fluttershy jumped at the impact, briefly yelling out in pain. Rainbow Dash repeated this, yelling things between slaps.

Rainbow Dash yelled "You're NOT supposed to cheat on your wife," then slapped her ass again, making Fluttershy gasp and jump from the hit. Rainbow Dash then repeated this. "You're not supposed to cheat on your wife. You're not supposed to cheat on your wife. YOU'RE NOT supposed to cheat on your wife, you fucking bitch!"

She then threw Fluttershy up and back onto the couch, shoving her against the armrest.

"I really just can't believe you," Rainbow Dash remarked, a disgusted look still on her face "I thought you loved me. I thought we'd be together forever. I didn't know you'd turn out to be a fucking whore. Guess I was wrong."

"Rainbow Dash, I swear, I do love you," Fluttershy said, still very stunned from being slapped.

"STOP FUCKING LYING TO ME," Rainbow Dash scolded, raising her voice into a yell, "I'VE HAD ENOUGH OF YOUR LIES FROM YOU IN THE LAST THREE YEARS!"

All Fluttershy could do now was cry, and she did. Tears started rolling down her face from her fear, guilt, and now, pain.

"Alright, fuck it. You wanna start crying? At least tell me where Scootaloo is."

This immediately made Fluttershy raise her head and stop her sobbing. Oh my god, she thought, She's going to kill our daughter

"NO!" She pleaded out, tears still in her eyes, "PLEASE, DON'T KILL HER! SHES OUR DAUGHTER!"

"Quiet down, bitch. I'm not gonna kill her unless you want me to. Tell me where she is. I want to tell her goodnight."

Fluttershy sat back, relived. She pointed at the door across the large living room hallway that led into the basement, a soundproof cellar that served as Scootaloo's bedroom by her request. "She's in her room."

"Wow, you had that fucker over here and didn't even bother to get the kid out of the house first." Rainbow Dash said, smirking. "Alright, I'm going to go tell her goodnight. And I'm not done with you yet. You stay right there. If I come back and you're gone, I'm going to go back down there and slit her throat. You understand?"

Fluttershy silently nodded her head.

"Alright, I'll be right back." Rainbow Dash said, before opening the door and walking in, shutting the door behind her.

Fluttershy sat the on the couch, shaking in fear, contemplating her fate. She was afraid that this could happen when she first started dating him. That she would get caught one day and have to face her horrible punishment. But she didn't imagine that her boyfriend and his son would both be murdered over it.

She stared thinking about her options. Maybe I should call the police she thought. No, if the police come she'll kill her for sure. I can't let my daughter die. I could never live with myself.

She felt hopeless, and just waited there, until Rainbow Dash came back.
