No Means No
by Shivered Timbers
(Prompt: None, actually, but this is SMPS-related.)
Applejack had her hoof around Twilight on the couch, petting her chest gently with the other, while Rainbow had been giggling to herself the entire time, and brushing her snout up against Twilight's ear every now and then.
"...So, in conclusion, Rainbow and I were wonderin' if'n you'd be interested in joinin' us for a little, y'know, intimate time. Just the three of us!"
Rainbow whispered into Twilight's ear, "I could teach you a thing or five about pleasuring a mare," before giving it a lick.
Twilight shuddered, and not from the amorous advances of her friend. While the concept of a threesome was new to her, and thus worthy of full scientific exploration, the way Applejack and Rainbow Dash had been... what was the phrase? Coming on to her, that's it. They way they'd been coming on to her left her feeling very uncomfortable. After all, they were her friends, and even if they'd been doing these things with each other for quite some time, she didn't think of them that way. There was only one recourse open to her.
The two mares stopped.
"Wait. Whaddaya mean, 'no'?" Applejack cast a glance at Rainbow, who shrugged and shook her head.
"I mean no! I'm flattered you would choose me, but I do not accede to these sexual advances. I would appreciate it if you would both leave me alone now, thank you."
Applejack hopped off the couch. "Well, if that don't beat all."
Rainbow Dash seemed thoroughly stymied.
"I don't get it. Was I not sexy enough for you, Twi?" She reached out to touch Twilight, but Twilight batted her hoof away.
"I won't say it again, Rainbow Dash. I'm warning you!"
"C'mon, Rainbow," Applejack said, turning and heading for the door. "Don't push 'er. It's obvious we went about this all the wrong way."
"No means no, Rainbow Dash," Twilight said, and crossed her hooves over her chest.
"Ugh, fine, whatever." Rainbow Dash rolled her eyes, kicked off backwards from the couch, pulled a loop midair, and then faceplanted straight into Applejack's crotch.
Applejack made a noise something like "WHOOEEEYAAAOHHH!" and fell over.
"Consarnit Rainbow Dash, I thought I told ya to stop doin' th--ohhh..."
"What was that?" Rainbow asked, coming up for air with a snoot full of Applejack's apple juice. "I couldn't hear you over the sound of how sexy I'm being."
"Wait a minute!" Twilight said, peering over the back of the couch. "What are you two doing?"
"What we were planning on doing with you, duh!" Rainbow rolled her eyes once more and then dove back into Applejack's vagina.
Applejack moaned and arched her back, one hoof tapping on the carpet.
"You didn't wanna join in, but that don't mean... Nnnf! That don't mean we can't have fun oursehhh... Ourselves!"
"But..." Twilight ducked down below the couch, until just her eyes peeped over. "You're in my house!"
"Can't hear you!" Rainbow called between mouthfuls of Applejack. "Too sexy!"
Twilight remained glued to the scene as Rainbow ate her marefriend out with gusto. Judging by Applejack's constant stream of vocalizations, Rainbow was quite good at what she was doing, too.
Twilight felt something very warm and tingly begin to grow in her genitals. It was arousal, she realized. She was being a voyeur and getting severely turned on watching her friends have loud, sloppy sex on her rug. Whatever had become of her?
"R-Rainbow!" Applejack cried. "Lemme... Unngh, oh mah stars, I'm gonna come if'n ya don't let up for a second!"
"Whew!" Rainbow gasped, taking a deep breath as she came up for air.
"Lemme taste ya, sugarcube," Applejack begged. Rainbow was all too happy to oblige, climbing atop Applejack and shoving her own labia in Applejack's face.
"Go to town, cowpony," she said, and turned her eyes toward Twilight.
Twilight couldn't help it. Her hoof was busy pleasuring her clitoris at a swiftly accelerating rate. In fact, the actual motion was following a logarithmic increase, perhaps even a Fibonacci sequence, all without her even having calculated the progression in her head. She gave Rainbow a pained look.
"So," Rainbow said, the word punctuated by a moan, "looks like you're enjoying our little show."
"Uh," Twilight said. She moaned as well, and a second hoof joined the first. "W-why would you, nngh, say that, Rainbow Dash?"
Rainbow shrugged. "Oh, no reason." She spread Applejack's hind legs so that Twilight could see the interior of her vagina. Rainbow, her eyes continuously on Twilight, leaned down, giving the engorged clitoris a slow lick. Applejack gasped and moaned, jerking upward into Rainbow's vagina. Rainbow then gasped as well and let out a small excited moan of her own, diving back into her partner's labia and munching Applejack's carpet like Pinkie Pie munched cupcakes.
Twilight clopped furiously.
"Uhhhhh," she hemmed, "is there any chance you'd let me change my mind, girls?" She grunted, closing one eye. "I mean, uh, I've kind of seen the, nngh, light, so to speak, and I'm thinking that maaaaybe, just maybe, I'd have a lot of, hohhh! A lot of fun with you two..."
Rainbow Dash and Applejack stopped simultaneously and craned their heads up to level deadpan expressions at Twilight.
"Twilight," Applejack said calmly, "you said no."
"And no means no," Rainbow added, nodding slowly.
"We wouldn't want ya to do anything ya didn't feel comfortable doing."
"And you deeeefinitely wouldn't feel comfortable doing what we're doing."
"Totally called it."
"Oh Celestia, AJ, eat my pussy!"
They resumed loudly slurping at one anothers' mons pubis, while Twilight, having stopped as well, found herself growing more and more sexually frustrated by the moment.
It wasn't fair! She could change her mind, right? This wasn't politics, after all. She went back to pleasuring herself with both hooves, but it wasn't enough. If she'd possessed a set of testicles, she'd be getting blue balls.
Blue ovaries. She was getting blue ovaries. The chromatic issues presented by that thought alone sent her into a further spiral of frustration and near-release. Seriously, what color were ovaries anyway? Textbooks always painted them pink, but she'd sort of assumed they were white.
Oh, dammit, Twilight, she thought, this is why you can't achieve sexual release!
Applejack came first, if her volume was any indicator. Rainbow followed soon after, shouting, "Holy Spitfire cloud shits!" in a tremendous display of post-coital word salad.
Twilight, on her back on the couch, heard more than saw anything, until the moment when both Applejack and Rainbow's faced peeked over the couch back.
"Hey, she's still goin' at it," AJ stage whispered.
"I noticed," Rainbow stage whispered back. "Think we should help her?"
"Well, as her friends, it would only be gracious of us to lend a hoof."
"Oh, but she said she didn't consent. Sorry, Twi, no can do!"
Frustration turned into anger. Twilight let loose a shriek of combined rage and lust and arched her back. Her vaginal walls began to secrete lubrication, while her cervix dilated. Various muscles around her body contracted and she entered a state similar to rigor before relaxing bodily, having made a small mess on her couch cushions.
"Wow, Twi, that was somethin' to watch!"
Twilight's cheeks flushed bright red. "That was really embarrassing, you guys."
"Hey, you got off while being watched." Rainbow grinned. "Maybe you're an exhibitionist!"
Twilight huffed and tapped her hooves together. They squished.
"C'mon, Rainbow, we should probably go."
"Yeah. It's been fun, Twi. Maybe you could write a letter to the Princess." She stared at a point in space slightly above and beyond the front of the couch. "A letter about how important it is to ensure consent is explicit when engaging in sexual activities."
"Yeah!" Applejack stared at the same spot. "Takin' a pony's consent for granted is only gonna lead to hurt feelin's and heartbreak. It's better to not have sex at all than assume you've got the right to do anythin' sexual with another pony."
"And once consent has been denied," Rainbow continued, "it can never be given again. Isn't that right, Twilight?"
Twilight glared at them. "First of all, you're both crazy. Second, I get it. I'm sorry if I snapped at you, you just sort of invaded my personal space and set me on edge."
Applejack and Rainbow smiled at each other.
"You're forgiven, Twilight," Rainbow said. "And we're sorry too. It definitely wasn't cool how we came on to you like that."
Applejack nodded. "Next time, we'll ask first."
"Uhh, well..." Twilight bit her lower lip. "I may not have consented to your first advances, but that was kind of then, and this is kind of now, and I kind of have sticky hooves and I'm not entirely satisfied, so if it wouldn't be too much to ask, well, maybe, would you two be willing to, uh...?"
Rainbow and Applejack leaned forward. "Yeees?"
Twilight blushed. "Consent to engage in mutual cunnilingus with me?"
Rainbow Dash looked at Applejack. Applejack looked at Rainbow Dash.
"You sure do talk funny, Twilight," Applejack said, and snickered.
"We consent, Twilight," Rainbow said.
They shared a long, relaxing laugh. And then they all fucked.
