I though your middle name was 'Danger'?
"Look! I swear, I'm telling you the truth!"
"Oh please," Rarity said whilst rolling her eyes, "Do you honestly expect me to believe that? If that were true I assure you I would have heard about it."
Rainbow Dash crossed her arms, pouting at the unicorn. She could not believe that Rarity just stood there calling her a liar.
The sun was setting and Rainbow Dash wanted nothing more than to be done helping Rarity so she could get out of there, but Rarity just had to challenge her. Typical Rarity... Why can't she just be a good friend and believe her.
"What's that's suppose to mean?"
"It means, that words travels fast and if you of all ponies would be true to that reputation, I would've known about it far sooner than you. Now stand still," Rarity frowned, as she tried to work around Rainbow Dash flailing arms, "How's that?"
Rainbow Dash groaned at Rarity's finicky. She hated dress fitting and frankly she wasn't sure why she was doing it in the first place, "It's too tight," Rainbow Dash complained.
"I thought you said you wanted it tighter?"
"Yeah, but now it's pinching my wings," Rainbow Dash shifted in discomfort, "I just want it to kind of hug my upper body— and don't change the subject!"
"What?" Rarity asked befuddled.
"What did you mean when you said, you'd know sooner than I would? How the heck would that work!?"
"The power of gossip, my dear." Rarity stated, readjusting, "How about now?"
Rainbow Dash moved around, stretching her arms and wings and torso to check the fit. It felt good now. Comfortable.
"It's alright."
"Tighter?"
"It's fine."
"Is it still pinching?"
"Look, I like it! It's fine, okay?!" Rainbow Dash exclaimed, annoyed.
"Good."
Rainbow Dash glared at her friend. Typical Rarity... Always fishing for compliments.
"By the way," Rainbow Dash frowned, "I think you're overestimating the power of gossip."
"Oh?"
"Yeah! There's no way you could have gotten the word of it, because the guys I'm with knows to never kiss and tell!" Rainbow Dash nodded, setting the final pin in the argument.
"Hahahah!"
"Wha-Why are you laughing?!"
"Oh please~" Rarity laughed in excess, "That's most absurd statement if I've ever heard one, darling. There isn't a stallion on the entire planet that would ever follow that rule. Once they're with their friends, it becomes a mandatory discussion."
"Well..." Rainbow Dash swallowed, "Maybe not for you—"
"Just give it up, Rainbow Dash," Rarity sighed as her laughter died down, "There's no way, no how, you're famous for de—"
"I am too‼" Rainbow shouted, turning to face Rarity, "I'll... I'll prove it to you."
Rarity blinked as she watched the upset mare glare at her, wearing a light blush on her face, "Oh? And how do you propose to do that? I certainly hope you don't expect me to call in some random stallion in here so you can—Aaugh!" Rarity shrieked and took a step back as Rainbow Dash unsuspectingly took one of her hooves into her mouth, "W-What are you doing?!"
"Straighten out your foreleg..."
"W-What?"
"It's about the right size for what I can handle," Rainbow Dash tried to smirk under her nervous blush, "Bet I could take it to the base."
Rarity stared in confusion at the mare, "You can't be serious! You're not expecting me to believe that—"
"I am serious!" Rainbow Dash exclaimed, "Now straighten it out or take back what you said!"
"You cannot take an entire foreleg into mouth, let alone to the base! That's ridiculous!"
"Were you even listening to me when I stood here talking?" Rainbow Dash sneered, "I told you! When it comes to sex, Deepthroat is my middle name."
Rainbow Dash smirked as she watched Rarity standing speechless and defeated before her. Now what was she going to do? She watched Rarity opening her mouth to speak but closed it in hesitance. Finally, Rarity peered over her hoof.
"Hmph!" Rarity harrumphed after a brief silence and stretched out her foreleg, "Don't choke on it..."
"As long as you keep it straight," Rainbow Dash grinned as she moved her muzzle to the tip of Rarity's hoof, "I won't."
Reaching her tongue out, Rainbow stroked the underside of Rarity's hoof with a subtle lick before opening her mouth wide and moving forward. Her warm exhales stroked the tip as it was held in the open gap of Rainbow Dash's mouth for a brief pause before moving further letting the tip slowly sink in to the back of her throat as the lips enclosed around the thick limb.
Rarity blushed, swallowing a moan as she felt the soft squishiness past Rainbow's uvula. She watched as Rainbow kept it steady in place with lips stretch around her girth, pausing before slowly pulling it back. Saliva stretch across the hoof as the tip reach back to the middle area of her mouth where Rainbow began a twirl, circling the thickness of the white intruder with her tongue as she squeezed her lips tight around it in a suckle.
Rainbow Dash felt her saliva build up as she swirled around tip, suckling the limb gently as she focused on not letting her lubricant for the act go on the floor or down her throat. As it filled her mouth, Rainbow let the hoof slip out and she rolled spit around inside for a moment before going down on Rarity once more.
Rarity let out a small gasp as she felt part of herself descend into Rainbow Dash's throat again, feel the warm tender texture as it moved to the back and even further as Rainbow leaned her head forward. Sinking into the throat, Rarity could feel the contracting muscles around her hoof as Rainbow swallowed it and let it travel down the depths, further and further. Rarity clenched her teeth in anxiety as she watched her friend bury her foreleg inside her, getting closer and closer towards her chest.
Rainbow groan subtly as she felt the elbow rest on her tongue, having swallowed more than half of Rarity's foreleg. She felt the thick girth deep in her throat become stubborn to move further down as the piped squeezed on it thoroughly. Leaning back, Rainbow let the leg slip out a bit before pushing forward with more force, taking it further down her throat, feeling the elbow pass into the depths as well.
Rarity bit her lip, holding back her pants as Rainbow Dash begun to thrust her head around the limb, taking it down more and more past two thirds of it's entirety. She watched her foreleg slowly disappear into her friend as the thrusts became a bit faster and more forceful and soundless whimper escaped her mouth as her ears picked up the subtle gaging and gulping sounds emanating Dash as the leg sloshed back and forth into her throat.
Rainbow Dash could feel the drenched limb punch her stomach as she reached further up Rarity's length through her thrusts. Seeing the goal line, Rainbow made a final thrust pushing forward with force and felt her muzzle slam into Rarity's chest as she reached the base of the foreleg.
Against her own will, Rarity let out a moan as Rainbow Dash reached the base of her foreleg, forcing her the entirety of it down her throat. Rarity could feel the tip of her hoof prod the tight entrance into Rainbow Dash's stomach as she heard the pegasus letting out a noticeable gag as she kept still holding her position at the base.
With her lips pressed towards her, Rainbow Dash could hear the pants as well as feel the light quiver from Rarity's leg as she kissed the base of the limb. She stroked her tongue, wiggling it the the under side of the leg and danced it out to taste the base as the felt shivers of the leg deep down her throat, playing gently with the muscle contractions. Rainbow Dash moaned as she began feeling the pleasures tickle in her lungs and began moving back, feeling the girth widen the more she let out.
Rarity stared as Dash began to pull out her quiver hoof from her body and held her breath as she stopped one third from exiting. With a fast blow, Dash shot her head forward causing Rarity to moan as she slapped into the base once more in a thrust and began pulling back once more.
Rainbow Dash slammed herself in another thrust towards the base, listening into Rarity's sound of defeat as the hoof punched into throat. Reaching her forelegs around Rarity's neck, Rainbow Dash held her grip as she began thrusting herself in pace against the base, picking up speed as she gag breathlessly around the limb.
Rarity panted heavily as Dash slammed into her again and again, letting small choking sounds around the quiver foreleg as spit drooled onto the floor in dancing motion. As Rainbow Dash picked up more force and speed Rarity could hear herself squeak as she felt the squish inside massage the leg as it punched the opening towards the stomach. With a final thrust Rainbow slammed hard into Rarity's chest and kept on trying to drill her muzzle into Rarity whose final moan became soundless in it's pitch as her leg quaked violently in the tightly contracted throat.
With a final gag Rainbow let go of Rarity's neck pushed herself out, feeling the spit coated limb exit her. Traveling back up from the depths of the throat, Rarity's hoof soon popped out of Rainbow Dash's mouth in sticky drool that spilled onto the floor as Rainbow panted heavily through the strings of saliva that coated her mouth as her tongue hung down dripping spit on the floor.
"S..See..." Rainbow Dash panted as she wiped her mouth, "I..I told you, I wasn't lying when I said—"
Before Rainbow Dash could finish she felt herself slammed onto the floor. Rainbow gasped as she saw Rarity towering above her and felt her strong hooves press onto her forelegs, holding her down. In panic Rainbow Dash began flapping and kicking but felt herself seize abruptly and noticed the magical grip that held her down.
"Rarity!" Rainbow Dash exclaimed, "W-What are you doing?"
"I'm sorry, Rainbow Dash..." Rarity spoke sternly through her shallow pants, "I'm sorry for not believing you... and I'm sorry for what I'm about to do."
"What?!" Rainbow gasped in fear, "Stop! Let me go‼"
"I'm afraid I can't do that, Rainbow Dash," Rarity leaned down, her face inches from Rainbow's, "Not after a display like that.
"R-Rarity..." Rainbow Dash whimpered in fear as she felt tears beginning to form.
"I hope you realize I have no choice here..." Rarity sighed in frustration, "But I'm going to have to rape you."
