Author's Note
I don't think I'm very good at setting up the events that lead to the explicit parts. I'm not good at romance. I also don't find it as good as Heat House. That just may be me. Again, there's no defecating in my view of porn.
Dangers of Egos
"No!"
"Come now, Dash," said Rarity, "It'll only be a half hour at most."
"I said no! I'm not gonna let you dress me up in frou-frou outfits!"
Rarity pursed her lips and thought for a few moments. She gave a fake sigh, "That's alright, I suppose. I'm just a little disappointed. You would've been the perfect size and shape for my next ensemble. I guess can't fulfill that order for the Wonderbolts."
"Wait, what?"
"I didn't mention? The Wonderbolts asked me to design some new outfits for them."
Rainbow Dash bit her lip, conflicted. On one hand, she didn't want to play dress up. On the other hand, she would be helping her friend and the Wonderbolts at the same time, "Ugh, fine. Just a half hour, though."
Rarity brightened, "Splendid! We'll start right away. Thank you!"
Rainbow Dash let Rarity drag her to the Carousel Boutique. Rarity led Rainbow inside an shut the doors and blinds, taking care to turn the sign on the window to show they were closed. Rainbow Dash found this odd but shrugged it off.
Rarity turned to Rainbow, "Now, take off your clothes and we can-"
"Wait, what?! Don't you already have my measurements?"
"You may have changed since the last time. Besides, we're both mares. There's no need to be embarrassed," reassured Rarity.
Rainbow Dash shifted uncomfortably. She let out a groan before taking her tank top and sport shorts, leaving her in her underwear.
Rarity cleared her throat, "Your underwear too, Rainbow Dash. I need to be precise as possible."
Rainbow reluctantly complied, now standing naked before Rarity. Rarity nodded and her horn lit up, bringing her measuring tape to her. She stepped closer to Rainbow Dash, admiring her toned body. She knelt down and started to measuring Rainbow Dash's thighs. She sniffed and smiled to herself, "Are you aroused, Rainbow?"
"Wh-what?!"
"You don't have to lie, Rainbow. I've seen the way you stare at me and my body. You're attracted to me, aren't you?"
"Y-yeah, as a friend!" How did she know?
"What would you say if I thought you more than a friend?"
Rainbow Dash stammered before Rarity suddenly stood up to eye-level. They stared at each other's eyes, Rainbow blushing while Rarity smiled coyly. Rarity leaned in closer, and Rainbow found herself doing the same. Their lips met. Rainbow smelled Rarity's perfume while Rarity found Rainbow's lips sweet.
Rarity suddenly pulled back, coughing, "I'm terribly sorry. That was too forward. Y-you can leave if you want..." she said, looking down in shame of what she done.
Rainbow Dash shifted, her nethers starting to become hot, "Wh-what if I don't want to leave?"
Rarity blinked and looked back up, "What?"
Rainbow rubbed her arm, "Y-you're right. I do like you. More than a friend..."
Rarity stood still, thinking before stepping back towards Rainbow Dash. They kissed again, this time more deeply. Rainbow couldn't help herself. Her hands trailed down to Rarity's butt. Rarity gasped and looked down. Rainbow Dash thought she had made a mistake when Rarity spoke, "I'm guessing you want to do something besides kissing."
Rainbow nodded. Rarity pulled away and undid her belt. This allowed the shirt that was tucked in it to be removed. This revealed that Rarity was wearing a black bra that covered her larger-than-average breasts. She put the belt and shirt away, then removed her bra. Her nipples were stiff in arousal. She took off her designer boots off. She slipped her long skirt down along her legs. Her black panties were starting to get wet. She took that off and revealed her pussy. She had trimmed her pubic hair into the shape of a rhombus. Rainbow shaved hers off in case she wanted to swim. Rarity put the articles of clothing away and moved to Rainbow Dash.
They kissed again, this time their tongues met. Again Rainbow couldn't help herself. Her hands went to Rarity's ass and squeezed them. Rarity was not one to be outdone and caressed Rainbow's smaller-than-average breasts. They broke their kiss, both panting. Rainbow gave Rarity's ass another squeeze and decided she needed it.
Rainbow Dash went down and behind Rarity. She grabbed a cheek in each hand, enjoying how they felt, "You have an amazing ass, Rares."
Rarity blushed at the crassness of Rainbow's words. Rainbow rubbed her face along one of Rarity's cheeks, taking in her increasingly arousing perfume. Rainbow kissed both cheeks and continued to knead them. Rainbow's finger traced around Rarity's Cutie Mark. Rainbow stared lovingly at Rarity's butt. This was her favorite part of Rarity's body. They were perfectly shaped and sized. Rainbow suddenly licked a cheek, earning a squeak from Rarity. Rainbow gave Rarity's ass more licks, wetting the thin fur. Rainbow ran her nose along Rarity's crack, starting from the top then to the bottom. Rarity smelled wonderful. Rainbow took in breaths through her nose as she poked along the crevice. Rainbow hadn't told anypony this, but she found scents incredibly arousing.
Rainbow suddenly dove her muzzle in Rarity's crack, earning a gasp. Rainbow breathed in and let out a moan. She pressed further in, taking deep breaths of Rarity's lovely scent. It was a very hot day outside so when Rainbow finally withdrew her face was wet with sweat. She licked her lips, enjoying the salty taste. Rainbow went back in between Rarity's cheeks. This time she went deeper. She found what she was looking for, Rarity's anus. She took a breath, enjoying the smell. Rainbow pressed further, her nose now against Rarity's asshole. Rainbow breathed in again. And again. She sniffed Rarity's ring for all its worth. Rainbow pressed even further, nose now entering Rarity's asshole. The smell was stronger here and Rainbow loved it. She found herself drooling as she sniffed Rarity's ass. She faintly heard Rarity moaning but the smell took first priority.
Eventually, Rainbow Dash found that she couldn't contain herself any more. She needed to taste it. Rainbow stuck out her tongue and tasted Rarity's anus. She and Rarity moaned. It was wonderful. Rainbow needed more. She pressed her face as far as she could into Rarity's ass. Rainbow slobbered over the anal walls. She licked in a circle before curling her tongue up and down. She drew back, getting another idea. She stuck her hand in Rarity's crack, feeling around. Making sure to get as much sweat on her hand as possible, Rainbow licked her salty hand clean. She put her other hand in and caressed Rarity's anus.
Rarity let out a gasp as she felt Rainbow insert her fingers into her. Rainbow wiggled her fingers around in Rarity's asshole, starting to thrust in and out. Rarity let out a moan as Rainbow increased her fervor. Rarity rubbed her clit furiously, rapidly reaching an orgasm. She screamed in pleasure as she came. Rarity breathed heavily, legs shaking. To her surprise, Rainbow wasn't done yet.
Rainbow Dash needed to taste Rarity again. She dove her muzzle back down, managing to shove it inside Rarity's asshole. Rainbow found herself fingering her cunt as she breathed in that heavenly musk. Her tongue came back out and licked everywhere she could. The smelly cavern clenched down on her as she lapped at the velvety walls. After a few moments of that, she angled her muzzle downward. She sucked at the walls with her lips, tongue teasing.
The taste and smell was getting to her. Rainbow took gulping breaths, drinking in as much of that musk as possible. She moaned inside of Rarity as Rainbow felt her own orgasm approaching. She forgoed her sucking and resorted to licking as much of that cavern wall as possible. Rainbow suddenly seized up as she came, squirting mare-cum onto the floor.
Rainbow withdrew from Rarity's ass, breathing heavily. Rarity looked at her sweat-stained face, getting an idea, "Let's go into the bedroom, shall we?"
Rainbow Dash nodded, eager for more. She followed Rarity up the stair and into her bedroom. Rarity went to a closet and opened a chest, "Close your eyes, dear. I want this to be a surprise."
Rainbow Dash complied and listened to Rarity rummaging through the chest. The sound stopped and a few moments later Rarity told her to open her eyes. Rainbow's eyes widened at what she saw. Rarity had a cock. A strap-on, of course, but a cock nonetheless. It was a foot long and a finger length in width. It was dripping with lube. Rarity grinned, "This is going up your ass, darling!"
"Uh..."
"Come now, Rainbow Dash. You played with my posterior, now I get to play with yours."
Rainbow Dash hesitated. It was so big. She bit down on the inside of her cheek before relenting, "U-uh. A-alright."
"Excellent!" Rarity moved to her bed and laid down on her back, cock pointing up, "Well, what are you waiting for?"
Rainbow hesitated again before nodding. She climbed up and straddled Rarity. The strap-on rested against her back. Rainbow gulped before she lifted herself up. The cock head pressed against her asshole. Not one for going slow, she sucked in a breath and pushed herself down as fast as she could. It hurt, but she expected that. Even with the lube, it was tough going. But Rainbow Dash was determined to hilt it.
And hilt it she did. She let out her breath as she felt the slightly cold length so far up inside her. She moaned as she lifted herself back up. She reached down to play with Rarity's tits. Rainbow let out shuddering gasps as she moved up and down the pole. The pain was starting to fade now, being replaced with a pleasantly warm feeling. Rainbow let out a moan, before squeaking when Rarity pulled her down to kiss. Rainbow continued to bounce up and down.
Her ass was starting to feel nice now. She reached a hand from Rarity's tits and started to finger herself. That gave her an idea. Rainbow Dash let go of the other boob and broke the kiss. She leaned back and reached her hand behind her. She found Rarity's ass crack and pushed the strap that covered her asshole aside. Rainbow started to finger Rarity's ass again.
Rainbow Dash looked down to see a small bulge in her belly. She watched it move up and down with her and found it extremely hot. She curled her fingers in her friends ass and extended it. She repeated this process. Rarity moaned at this. Rainbow was getting close. Starting to breathe heavier, her moans grew louder. She fingered Rarity faster, determined to make her cum with her.
Rainbow Dash succeeded. They both screamed to the heavens as they came. Rainbow Dash's anal walls clenched down of the strap-on. Rainbow recovered first and withdrew her fingers from Rarity's ass. Rainbow gave them a sniff, happy they smelled like Rarity. Rainbow then sucked on the sweaty fingers. She moaned and pushed herself off of the strap-on. She still wanted to taste Rarity. She turned around and started to undo the strap on. Rarity looked down to see Rainbow's anus gape. She could clearly see the red flesh inside.
Rainbow managed to get the strap on off. She repositioned herself and lifted Rarity's hips up. Rarity was covered in sweat. Score. Rainbow licked at the flesh in between Rarity's pussy and asshole. She stopped quickly, wanting to smell it first. She pressed her nose against that tender, sweaty flesh and breathed deeply. She rubbed her nose all over the area. Rainbow finally lapped the sweat up. She loved the salty taste. She kissed and licked the flesh before running her tongue under the sweaty curve of Rarity's butt.
Rarity had already started to finger herself at the first lick. She started to pant and moan as Rainbow assaulted her. As Rainbow licked, she thrust her fingers up Rarity's butt yet again. She spread her two fingers, spreading Rarity's ring wide. She moved the spread fingers back and forth. Rarity gave a moan at that. Rainbow continued to lick at the salty flesh until her tongue began to get tired. She resorted to kissing.
Eventually Rarity came, legs shivering. Rainbow Dash retreated her fingers from Rarity's clenching anus and licked them. She gave one last sniff up Rarity's butt before crawling up to give her lover a kiss. They eventually broke their kiss and Rarity nuzzled Rainbow Dash, cooing, "That was wonderful. Thank you."
Rainbow's head was dizzy from all the smells but grinned nonetheless, "No problem, Rarity. Do you still want to take my measurements?"
"Not right now...Let's just stay here for a few minutes more..."
As they laid next to each other, Rainbow Dash started to think. She was happy. Happier than she felt in a long time. She finally had a special somepony. She sighed happily, thinking to the bright future...
