A Thin Line

The six friends had more fun that night than at any party they had before.

The party was completely planned out and regimented, but that was only behind the scenes. In practice, nopony noticed the way that everything was planned since all the events flowed so well from one to the next. A quick but absolutely boistrous game of pin the tail on the pony flowed seamlessly into a ranbunctious pillow fight. They followed that up with mud facials to freshen up, and that overlapped and eventually completely transitioned into gossip about the town and its residents.

Clearly, Twilight had done her homework this time, and she was getting to the point that she could throw parties like Pinkie Pie, though Rarity was led to believe that Pinkie did indeed provide at least a little help with all this.

Twilight also seemed to have done an analysis on all their friend's interests, or, more likely, she already knew them so well after being such close friends for these past few years, and was clearly trying to please everypony with an event that catered to their interests, but still left plenty of room for the others to enjoy it. While Rainbow was on the fence about the mud facials, she found that she enjoyed it quite a bit after she tried it.

Everypony was smiling the whole time, and all of their faces were tinged with red due to the joy they experienced that night. At one point, Twilight broke out some red wine, a gift from her sister-in-law, Cadance, but everypony simply sipped at their glasses, not wanting to spoil the night by getting too drunk and forgetting it or, even worse, ruining it.

After all the planned and catered events, it all culminated in a grand game of spin the bottle that was supposed to be fun for each of them, and sure to be forgotten by none of them.

"Ah think we should go clockwise, startin' with Twi." Applejack suggested.

"No way AJ, we should totally have a competition to see who wins the first pick." Rainbow countered.

"Well, ah was just thinkin' that maybe we should keep it fair for our friends that might not be able to keep up!"

"Or maybe those who CAN keep up deserve to go before the others!"

It was common, almost customary, for these two to have a little bit of a scuffle at every get-together, but Twilight was quick to break this one up, being how excited she was for her party to end on the perfect note; the final piece that would truly make this the best night ever.

"Alright, you two that's enough. I'm not sure if all of you even know how this game works, but I'll go first to demonstrate." Twilight began. "It's actually pretty simple. All you need to do is spin the bottle on your turn, and, depending on who it lands on, you ask them truth or dare. Whatever they reply, you get to either demand one truth or get them to do something of your choosing, respectively." Twilight seemed confident in her descriptive yet succinct explanation.

"Oh, so I can make AJ here go and fetch me a drink?" Rainbow chimed in.

"Hey now, Dash, I'm not -" Applejack began.

"Assuming it's your turn, the bottle lands on her, and she asks for a dare, yes, actually!" Twilight replied, enthusiasm evident in her tone.

"Sweet!" Came the reply from Rainbow Dash. At Applejack's glare, she added "Aw come on Applejack, I'm just messing with you." This served to mollify her a bit.

"Alright, now I'll begin. I'll just spin the bottle... and that's me, so I'll just spin again... alright, looks like it's you, Fluttershy." Twilght said as she started the game. "Alright then, Fluttershy, truth or dare?"

"Um, I think I'm gonna stick to truth this time, Twilight." said Fluttershy.

"That's fine, Fluttershy. Hmmmm... Oh, I know! Have you ever had any coltfriends? I know that's a good question, my research told me it was a surefire way to have fun at this game." said Twilight.

While the others were slightly taken aback by Twilight's brazen question, her apparent innocence combined with their own undeniable curiosity kept their words in check. To their surprise, Fluttershy answered.

"Ummm, well, no, not exactly."

"Hmmm, alright then, I guess it's now Rainbow's turn." said Twilight.

Nopony was exactly surprised with the answer itself, but it was still a revelation to know with certainty that Fluttershy had never dated a colt before.

"YES! Alright, one of you suckers are so getting dared" Rainbow Dash spun the bottle, and it landed directly on Rarity. "Oh, looks like I got you, Rarity, alright then, I dare you to-" Rainbow began.

Twilight cut her off, saying "Actually, Rainbow, you're supposed to ask her whether she wants a truth or a dare."

"Oh, yeah, right... so then, truth or dare, Rarity?" Rainbow Dash amended.

The alcohol almost convinced Rarity to be adventurous and take a dare, but then she made her decision. "Truth, of course." She replied.

"Alright then, have you ever kissed... a mare?" Rainbow asked.

The question was a little out of left field, but not exactly uncalled for, since it was well known among them that Rainbow Dash was attracted to mares. She simply didn't have a relationship since she decided not to in lieu of her physical conditioning.

"No, and I may never." Rarity replied. She wasn't sure exactly how true that statement was, however, what with the previous encounter she had with Twilight in her room. A blush came to her cheeks.

"Hmm... I'll take that no for now, but the blush is telling me that might not be the whole truth." Rainbow replied. Her soft smile belied her good intentions.

Around the room they all took their turns, and it was mostly trivial tasks or the occasional question about their dating habits. To many of their surprise, all the answers to the more romantic questions were negative, and it seemed as if none of them had dated or even really had kissed before, except Dash and AJ, who swore they kissed a filly and a colt, respectively, when they were younger.

Eventually, Rainbow Dash's turn came back around, and she spun the bottle to have it land on Rarity again.

"Alright now, truth or dare, Rares?"

Rarity was now feeling adventurous again, and took her first dare of the night. "Dare me." She replied.

"Alright Rarity. I dare you to..." Rainbow Dash took a glance around the room, and her gaze landed on Twilight. "Kiss Twilight." Rainbow Dash crossed her arms, a smirk on her face.

"What? You want me to... oh, well, I guess it IS the rules." While it seemed simple on the outside, it was anything but on the inside. Her memory flooded with images of Twilight, naked, with her incredibly tight flank on full display only inches from Rarity's face. She visualized the tight core of her body leading up to her full breasts, and the cute librarian face that she seemed too innocent to notice.

Rarity failed to notice that Twilight had already come over, both of them kneeling on the ground, and Twilight's slender hand was on Rarity's shoulder.

"Well Rares, are we gonna do this? In front of them?" Twilight asked. Her blush betrayed the fact that similar thoughts were likely running through her mind.

Rarity couldn't take it anymore. She answered by gently leaning forward and pecking on the lips, then pulling away in embarrassment. It only stoked the flames.

Rainbow was about to speak up and jokingly complain about their feeble kiss, but then Rarity went back for more without any prompting, taking all of them, including Twilight, by surprise. The sexual tension between them finally diffused.

Only to be replaced with passion.

The other four watched in awe as the kiss kept going. They let out a slight collective gasp as Rarity tilted her head sideways and placed her hands on Twilight's upper arms, then drew her in closer, their breasts mashing together between them. Twilight's shocked, wide-eyed expression soon faded, and then she appeared to begin reciprocating. Rarity's tongue darted out on instinct and invaded Twilight's mouth. It was weird at first, but then she realized that it was fun to push back and forth with their tongues, so she did the same.

"Mmmmmh." They both quietly moaned.

At some point, They realized how long they had been kissing in front of their friends, and almost forcibly came apart, a strand of saliva connected by their lips and dangling between them.

Rarity looked down and saw that both of them were undeniably aroused, wetness showing through their panties.

As the two gazed around, they saw all their friends wore the same expression; shocked amazement. They were stunned into speechlessness, while Twilight and Rarity simply sat there, holding each other and blushing. Rarity couldn't help but run her hands through Twilight's mane. It was just so soft.

Rainbow Dash was the first to break the silence.

"Wow... that was... that was, really hot, you guys. Thanks, I guess?" At first, the twosome blushed even harder, if that's possible, but then they turned their heads back towards each other and stared into each other's eyes. There was definitely something in their gazes that wasn't there before, and everypony else could notice it too. They simply couldn't find a name for it.

Twilight and Rarity looked down to Dash's crotch and spied wetness between her thighs as well. At this, they smirked and leaned back into each other for a quick smooch, just to tease, then finally disengaged and Twilight walked back over to her place in the circle.

"Well, um, I guess we should... continue the game?" Twilight suggested.

She was met with a chorus of approval. While the other Elements weren't completely sure of what had happened, they knew that Twilight and Rarity now shared a special, deeper bond, and they wanted it too. It was evident while they kept playing, doing some standard rounds in the interim to cool off; Twilight and Rarity kept shooting each other glances, and they appeared to be speaking on another level that the others couldn't understand. When it came to be Twiliight's turn, she spun the bottle and it landed on Rarity.

"Rarity" Twilight whispered with half-lidded eyes. "Do you want truth or dare?"

Rarity simply sat with a glazed expression for a few moments as she allowed the sultrily delivered question to sink in. "Dare me, darling." came her reply.

The group sat with bated breath, waiting for what Twilight would dare Rarity to do; how she could possibly up the ante.

"Rarity, I want you to... strip for me." said Twilight.

Rarity's face shifted through a few expressions: one moment of offense, followed by a scrunched up face that signified her thinking, then a look of resignation as she stood up, and finally an almost... fiery look as she reached for and grasped the hem of her shirt and began to lift.

Rarity took it slow, something was telling her to be a tease, as if Twilight would enjoy it more. She didn't have much clothing on in the first place, however, so she simply lifted it slowly, revealing inch-by-inch of her magnificent white coat, and then she began revealing her breasts, the material stretching to curve around them. She let the material slide over her now hardened nipples, and let out a light gasp as the pleasure shot through her system. With her nipples revealed, she made a deft move and quickly removed the rest of the midriff, standing topless before her friends, and striking a pose for Twilight.

After Twilight was finished staring in awe, she spoke. "Rarity... I meant all of it."

Rarity smirked, simply said "I know," and turned so her rear was facing her friends. She bent over, lifted her tail, and began to pull the material down her body. The center was stuck to her wet vagina, and made a light sucking noise as it finally parted from her body. All of them could see the drop of Rarity's arousal that fell from her marehood. She continued dragging the panties down her long, white legs, and continued bending over, presenting more and more of her dripping mare hood to her friends. When the panties finally reached the floor, she gave her flank a little shake, and stepped out from over them. She gathered her top and panties from the floor, and threw them somewhere else across the library, all the while keeping her eyes fixed on Twilight, who couldn't stop returning her gaze.

"Is that what you wanted, dear?" Rarity asked Twilight. She dropped back down to sit on a soft cushion in such a position that her bare, prodigious breasts were thrust forward in Twilight's direction. "I don't know what I'm doing, or why I'm doing it, but it just feels... natural." She thought to herself.

Twilight didn't answer, she just allowed the drool collecting beneath her tongue to escape from her mouth. She didn't even notice when the bottle spun again and landed on her; it was Fluttershy's turn.

"Twilight, uhm, do you want to tell the truth or do you want a dare?"

Fluttershy's voice served to knock her out of her trance, and she had a determined look in her eye now. "Dare."

"Oh, okay, I was, well, that is to say I... I... I dare you to, maybe kiss me."

Without hesitation, Twilight seemed to glide over and place her hand behind Fluttershy's head, briefly stroking her silky mane before drawing in for a kiss.

Twilight, already having a bit of experience, pushed forward first, "mmmm" ing and turning Fluttershy's head sideways to allow her tongue better access. Fluttershy was still taking it passively, but that was natural, considering her nature.

The others gazed on, and Rarity was particularly flustered given that it was Twilight kissing her, on top of the increased sensuality from simply being nude. As Rarity gazed at the passionate kiss, she felt her nipples begin to ache and the juices from her marehood flowed faster, staining the pillow beneath her. Subconsciously, she raised a hand to rub one of her breasts, licking her lips as she did so.

The other members of the mane six were in varying states of arousal. Applejack seemed resistant, but not entirely turned off, Pinkie watched with the curiousity of a filly discovering a new potential friend, Dash was watching with a big smile on her face and a blush across her cheeks, apparently pleased with the turn the party was taking. Twilight was obviously aroused; her panties were soaked through, and one could faintly make out Fluttershy's nipples poking through her thin night gown, signifying they had hardened in response to Twilight's advances.

Finally, Fluttershy seemed to be getting into it. She snaked her tongue out into Twilight's mouth and wrestled her tongue lightly. She even moved her hands down and, in a surprisingly daring move, grasped at Twilight's flanks, her hands covering Twilight's cutie marks.

This earned another "Mmmmm" from Twilight, who redoubled her efforts and pulled them even closer, mashing their breasts together like she had with Rarity just earlier.

Rarity had been massaging her aching nipples this whole time, and let out a soft "ooooh" as she tweaked one. The action alleviated the pressure, but increased the flames of arousal that burned below. She looked up only to notice that her noise had attracted the stares of her friends. She blushed in minor embarrassment and gestured for them to continue the game; even Fluttershy and Twilight Sparkle had pulled apart to look at her.

It was Pinkie Pie's turn now, and when she spun the bottle it landed on Applejack. "Oooohh, Applejack! Alrighty then, truth or dare cowpony?" she asked.

Applejack was as interested in the way this party was going as anypony else, but she didn't show it. "Dare me, sugarcube."

"Hehe, okaaayy! I want you to strip just like Rarity over there; everything must go!" Pinkie Pie seemed to be going with the flow this time, and was clearly in the spirit of things. Her grin was positively massive.

While it was kind of unexpected, Applejack had secretly been hoping for a request like this. "Sure thing." And she did it quick and business-like, with the air of a pony that wasn't afraid to show their body off to the whole world. The others could see why she was confident in her body; it was positively beautiful. She was cut and toned all over, sporting slightly larger muscles that most mares, but her strength was mostly lean. She was actually stronger than most stallions, too. her breasts were huge, being similar in size to Rarity's, though they hadn't noticed before since she tended to bind them up, while Rarity flaunted her 'gifts'. She even undid her hairband and let her blonde mane fall naturally around her shoulders. She had left her stetson at home this time, since it wasn't required when they were inside all night, and she didn't want to risk forgetting it when she took it off to go to sleep. She posed much like Rarity had before her friends, seeming to pay particular attention to Rainbow Dash, who was clearly the most interested.

Rarity was first to speak, this time.

"Darling, you simply must come over more often and allow me to design outfits for you. You have a positively beautiful body, and I know just the thing that would really bring out those curves." she said.

"Why, shucks, Rarity, thanks for the compliment." Applejack said with a blush, her small smile made it apparent that the comment was sincere.

The game had escalated at that point, with every round being a dare, and before they knew it all of them were naked, then Pinkie dared Applejack to kiss Rainbow Dash, where Dash made a grab for one of the farmer pony's large breasts and managed a good squeeze before they broke apart. Next, Applejack dared Rainbow Dash to kiss Twilight, and then Twilight dared Pinkie Pie to kiss her, and then Rarity dared Fluttershy to kiss Pinkie Pie.

Eventually, every kissing combination was exhausted, and the Elements were all significantly flustered. Their nipples ached, with them looking at each other and occasionally stroking a breast, and their marehoods leaked, soaking the pillows they sat on. Finally, it came back to Twilight, and she thought of a way to ante up while she spun the bottle once more. They had dropped all pretenses of Truth or Dare, now it was just Dare.

The bottle pointed directly to Rarity, who wondered what could possibly come next, but she was excited to find out none-the-less.

"Okay, Rarity, I want you to... touch yourself..." She appeared to have some difficulty stating it, even after all the snogging they had done tonight. "...and you have to reach orgasm." She added.

They all had experienced masturbation, or 'clopping', as the Ponyville slang went, before, and actually they had all engaged in it quite often since their first heats, so they were well aware of what was to be in store for them if Rarity followed through. After some thought, she made a decision.

"Alright, dear, but only because you're my friend." Was her reply.

Rarity leaned back, presenting her dripping marehood for them to see, and then slowly drew one hand over to her vagina. She focused on herself in this moment, picturing Twilight's sexy body for the first time during a clopping session, and then it became easy. She began rubbing her dripping outer folds to prepare, which caused her to coo in pleasure, and made her nipples ache ever so deliciously as they often did when she masturbated. She brought another hand up to one of her breasts and tweaked a nipple, earning a soft "ooooh" like the one that distracted the others before. At this moment, she plunged two of her fingers deep inside her vagina, and a wet *squelch* could be heard with each time that Rarity's fingers pumped in and out of herself.

It was unbelievably sexy.

The rest of the mane six had huddled closer towards Rarity, watching her masturbate with a marked interest, but Rarity never noticed, keeping her eyes closed the whole time.

While she made a point earlier to keep her mind on Twilight, she found her mind drifting to her other friends and their incredibly sexy bodies. Rainbow Dash, while the smallest in the chest of the group, still boasted a pair of Cs, or maybe borderline Ds now that she thought about it. Her body was athletic, thin, and toned. Few curves, but it held a certain power that got her wet. Next, she thought of Pinkie, who's body was similar to Twilight's; nice and curvy, not overtly sensual nor too flat, then she thought about Fluttershy, with her demure sweetness belying an incredible body with wide hips and large DD cups, which looked huge on her small frame. Applejack got her going mostly because of the visible muscle and massive breasts to rival her own.

Rarity was unashamadly moaning now, plunging three fingers into her steaming marehood and constantly tweaking one nipple or the other. Her back arched and she brought the hand on her breast down to her vagina and placed two fingers on the edges of her outer lips, proceeding to draw it open. "I'm so close!" was the only thought in her head. She had exposed her engorged clit, hiding beneath its hood, and tweaked it, instantly sending her over the edge in the best orgasm she had of her life. She positively sprayed juices out of her vagina, coating her hands and her inner thighs in the sticky substance, not to mention the floor in front of her. Twilight thought she felt some of it land on her knees from her kneeling position several feet away, but was too busy gazing in awe and lust to truly notice.

What they failed to notice is that Rarity was still going. The sexual tension was so thick that she was sure she still had another orgasm in her, the dare forgotten. She resumed plunging her sopping fingers in and rode out the pleasurable spasms of the first one even as she was coming up on her second. The contractions and increased sensitivity only made it easier to cum a second time. The mane six noticed as her moans began to pick up again, and then she screamed in pleasure as she brought about her second orgasm easily. The mess was even greater this time, coating more of her legs and practically sticking her fingers together. In the haze of lust as she rode out the spasms, she brought one of her cum-soaked hands up to her mouth and licked, tasting her own fluids.

Rarity simply lied there in the afterglow, and her thoughts turned to each of her friends. They had stuck together through so much to come this far, and now they were exploring a new branch of friendship, something deeper for all of them to experience that would draw their bonds tighter. She realized that their bodies weren't the only things she was attracted to, or else she would've settled for that Blueblood character. What she really valued was the way they complimented each other and provided so much support. All the little things like stopping by just to say hello or inviting the gang over for dinner or, she smirked, a slumber party. Rarity felt the need to give the same pleasure she had received. The problem was, she didn't know how...

The rest of her friends slowly made their ways back to their positions one by one, each thinking similar thoughts, and on top of that different ways to express "That was the hottest thing I've ever seen, and I want more of it."

They wasted no time in starting the game up again, and Rarity eventually sat up with a warm glow about her. It was Dash's turn to spin the bottle, and it landed on Fluttershy.

"Fluttershy, I dare you to do the same thing Rarity just did, and that includes the second orgasm." She'd be very pleased if she could get Fluttershy to accept something like this.

Against all expectations, Fluttershy said something that made all of their jaws drop.

"...Wanna help?"
