White, Purple, and Rainbow
"Are you sure she's not hurt with all that stuff on her?" Twilight asked, standing beside Rarity in her bedroom.
"No need to worry, darling, our little pet will be perfectly alright with something so basic" Rarity chuckled, looking down at none other than Rainbow Dash. The shemale pony lay down on Rarity's bed, stark naked, with a throbbing erection going on. Her legs were held apart by an iron bar around her feet, and her knees were tied together to keep her legs bent forward. Her wings and hands were also tied behind her back, and she was blindfolded with a ball-gag in her mouth as well.
"I'm still not sure I can go through with this" Twilight said, Rarity coming out in her usual mistress attire; a tight, black corset that pushed her already generous bust up to look perkier than normal, a plain black thong showing off her lovely, marshmallow colored cheeks, even wearing a masquerade mask that covered the front of her face and a dominatrix cap atop her head. Twilight knew she liked to dress up like that, but she still found it weird.
"Twilight, please, she owes us both a night of passion and fervor, so if she has to do it like this, it's of no consequence to anyone. It's just a little harmless fun" Rarity scolded as she ran her fingers across Dash's chin and the side of her face, the Pegasus squirming slightly as her cock twitched. "See, she knows how exciting this is" she giggled.
Twilight mostly just blushed as she took her glasses off and set them down on the nightstand, then climbed up onto the bed to momentarily undo Dash's gag and ask "Are you sure you don't mind this?", to which the other mare nodded.
"I don't mind" Dash quickly answered, just in time for Rarity to readjust her gag back on and poke Twilight's muzzle.
"I agreed to only use my least harmful equipment for this, but that doesn't mean I like it to be easy and painless. I fully expect you to cooperate with me" Rarity scolded with a little huff.
"I'm just going to handle her a bit more...traditionally" Twilight ultimately said as Rarity went off to look for something to tease Dash with. In the meantime, Twilight took the opportunity to pepper Dash's neck with sweet little kisses, her fingers tracing small circles down her modest, blue nipples and heard the bound Pegasus swoon. Ever since first discovering the amazing powers sex had in the world, Twilight took the time to learn everything she could about it, and also learned a lot about pleasuring someone, even in the most trying of situations. As such, she wanted to make certain Dash felt as best as she could.
Rarity soon returned with a feather and a charming smile on her face as she approached the two on her bed. Taking the feather with her magic, Rarity tickled around underneath Dash's testes and around her slit, forcing her to cringe a bit and moan out to the tune of Rarity's giggling. Twilight kept a close eye on Rarity to make certain she didn't go overboard like she normally would, and of course, Rarity acted very carefully. For the time being though, the purple librarian just massaged her shoulders and focused on her pleasure while Rarity just went and kept on tickling her shaft.
Soon enough, Rarity set the feather down on Dash's chest and began tickling the modest blue boobs of hers, making her laugh beneath her gag with a notable smile. Twilight just smiled internally as she stroked her shaft and suckled upon her neck and shoulder. Rarity soon giggled once more and joined in on the stroking fest as her gloved hand went over the rigid flesh that didn't have Twilight's paws on it. The way it throbbed, the way it purely reeked of need and musk, it drove both of the mares crazy inside as they began to bathe her in their tongues.
Twilight couldn't resist reaching down below Dash's blue balls and stroking along her folds, causing Dash to let out a pleasured gasp and jump a little. She may have been bound, but her reactions were still clear as day.
"Ooh, how saucy of you, Twilight" Rarity cooed as she leaned across Dash's body and engaged Twilight in a deep, sensual kiss. The two unicorns traded moments where their tongues danced about, wet sucking and schlicking sounds coming from the two as a hand was on either Dash's cock or stuck in her pussy. Rarity's magic soon came alive and Twilight gave a sudden gasp and a sensual moan came from her as the mistress smiled and magically fingered her with a lusty look in her eyes.
Twilight bent over and wrapped her tongue around Dash's ailing shaft, licking down the base of it slowly as she got a taste for her favorite treat for the longest time. Rarity rubbed the back of her head with one hand as she kept on pleasing her friend with her magic, leaning over to trace her tongue around one of Dash's breasts. They may not have been as big as the rest of her group of friends, but they were certainly enough to enjoy.
"Oh, that reminds me of something I read from a book" Twilight said as she noticed the action going on beside, backing off away just long enough to wrap her plush breasts around Dash's shaft and stroked her off, the muffled sounds of Dash's appreciative moaning resonating with her ears as she kept it up. Rarity was focusing her magic around Dash's balls and caressed them ever so gently in the meantime, wanting to make certain she knew who was pleasuring her.
After a few straight minutes of stroking and suckling, Twilight had started reaching the end of her rope as she started to climb up onto her and mount the bound shemale carefully, only to be grabbed by Rarity, all of a sudden.
"Are you sure you'd rather skip to the chase. It seems awfully vanilla, don't you?" she asked, quirking and eyebrow.
"There's only so long you can suck and lick upon a penis before wanting to ride it" Twilight said as she dropped her equally plush hips directly down upon Dash's rod, both of them letting out a lewd moan with incredibly pleased grins on their faces as Twilight sat and adjusted herself to Dash's cock once more. Each time their hips connected, she immediately brought them back up and bounced right back down, her breasts swaying and bouncing majestically to the beat as Dash made small thrusts right back up into her.
While Twilight was having vanilla sex, Rarity soon found herself leaning down and licking around Dash's cock as it was sufficiently covered in Twilight's juices, even rubbing along the starburst cutie marks of the latter's curvy rump and giving it a firm smack. Naturally, the purple pony gave a pleasured yelp and moaned out as she soon started grinding her crotch down into Dash. After that, she started firmly rubbing her horn between Twilight's plush cheeks.
"Rarity, what are you do-HING!" Twilight moaned as Rarity soon shoved her horn directly up the former's anus, giggling to herself as she soon shoved her fingers up Dash's pussy as best she could without hurting either of her two friends.
"Making certain you both remember tonight" Rarity chuckled as she fucked Twilight's anus and fingered Dash, both mares moaning deeply from the feeling of her appendages. Rarity then set her horn to begin buzzing inside, causing Twilight to moan more as she bent forward and embraced Dash, her legs holding her still and steady upon her cock as her ass was made into Rarity's plaything. The buzzing sensation made her swoon, her internal walls clamping down hard on the white bone, her magic making a bubbling sensation up her rectal cavern as she felt herself practically cumming already.
Twilight's entire face was flushed as her eyes rolled back into her head. She never imagined Rarity would be capable of using her horn for something so amazing. She couldn't think of anything before suddenly hearing and feeling Rarity's magic get more intense, suddenly noticing the presence of hands on her rump as she looked back to see Dash was suddenly unbound, but before she could do anything or say anything, she felt Dash begin moving inside of her once again.
Rarity giggled from where she was and kept her horn thrusting into Twilight's ass as she tugged on her tail and gave her flank a firm smack.
"Even with all those books, you still don't know anything" Rarity smirked as she continued to please Twilight with her horn, Dash doing her best to please her using her horn too. All Twilight could even think of in the meantime was how amazing it felt to have two different things being thrust into her at one time, her mind soon melting under the incredibly powerful passion in the room.
Each little motion sent her pleasures skyrocketing as she felt herself cumming extraordinarily fast, soon coating Dash's lower body and some of Rarity's faces with her juices. Rarity soon extracted her horn from Twilight's anal cavity as slowly as she could, standing up with a little smile as she licked the juices off of her face and then headed off to the washroom to scrub her horn clean. This would of course be the one major problem with anal-play using a horn; you never know when someone did any work washing such an orifice, and even if they did clean it, you could never take chances.
That just left Twilight to catch her breath as she lay on Dash's chest, her face cutely flushing and her sensual body beginning to cool off after such a powerful release. She leaned up and undid Dash's gag to kiss her properly, their tongues dancing gracefully as they exchanged saliva between one another gracefully. Drying off her now sterilized horn, Rarity returned in time to give a pleasant smile at the two on her bed. She soon came up and helped pull Dash's cock out of Twilight's snug pussy, brushing up against her ass and nuzzling her tail ever so slightly as she suckled Dash's hard cockhead sensually.
Dash moaned out into Twilight's mouth as the two wrapped their arms around one another, neither one wanting such a moment to end. Of course, Rarity still needed to get some for herself, and they knew that perfectly well. At the very least, she was just tending to Dash's shaft with innocent intent for the time, seeing as how not even she could separate the two from how they were now. She stroked along the still-throbbing tool as she reached up with her head and licked along Twilight's puffy lower lips, now giving her a reason to moan more as her sensitive lips were licked with quite the fervor.
"R-Rarit-hee!" Twilight moaned out, putting a smile on the marshmallow colored pony's face.
"That's right, you know who's in charge" Rarity chuckled as she continued tasting Twilight more, her slightly stretched walls converging around her tongue as Dash's rod hardened from the cute sounds of her moaning. Rarity increased her slurping and lapped away at more juices seeping out of her librarian friend, soon dragging her tongue all across her plush cheeks before once again smacking it, making her moan out and loving the slight echo of it.
"Oh, this so-soooo good" Twilight moaned out, Dash chuckling and rubbing her back slightly.
"We know, egghead, you've been moaning for at least half an hour now" Dash answered, kissing her once again as Rarity son stood up and moved Twilight off onto the side of the bed before mounting Dash herself.
"I hole you're not too busy to help tend to me too" Rarity chuckled sensually as she soon slid down Dash's rod with a smile and a moan on her face as she sped up her bounces quite more than Twilight did when she was riding her earlier. Dash moaned out more as Twilight soon rose up with a wanting look on her face, being guided to engage Rarity in a deep kiss as the mistress soon traced her hands all across Twilight's curvy body. Dash soon joined in in trying to caress Twilight as she blindly groped up her body until she could find her plush, purple melons and make Twi moan more.
Rarity's hips jiggled and bounced about as she continually rode Dash to her own orgasm, making certain she did everything that she could to keep either of them from climaxing too soon. She still had plans for how she wanted to handle them both, and until they were both close to climaxing, she wouldn't allow either one to cum first.
Twilight moaned out mare as she sat down on Dash's muzzle, her pussy lying right on top of her mouth as she better embraced Rarity. She and the fashionista both took the opportunity to pleasure one another's mouths as best as try could while their tails began swaying, brushing against either end of Dash's body as they soon began to grope one another's chest ever so sensually. Twilight and Dash were both moaning rather lewdly at this point, but leave it to Rarity to keep her composure, even with sixteen inches of hard Dick in her cunt.
It didn't take very long before Rarity soon felt her stamina coming to a close as her climax was coming sooner than expected. She quickly began to bounce upon Dash's lap rather quickly, her magic coming to life and magically forcing itself into Dash's own pussy, making the Pegasus moan up into Twilight's. Not long after, and a harmonic choir of moans soon started filling the room as all three came at on time, Dash's rod roughly squirting straight up into Rarity's snug tunnel as the trio of mares could hardly stay up much longer.
"So... awesome..." Dash breathed as she was wiping Twilight's juices off of her face.
"One could certainly say that. I must admit, it was definitely alright, even if it was rather plain" Rarity added as she changed out of her dominatrix outfit and into her dark blue night gown. Of course, even that was rather provocative with the way her nipples were barely covered.
"It was amazing as always, thanks for doing this this for us, Rainbow" Twilight cooed sensually as she embraced the Pegasus endearingly.
"Do be sure to save it for the camera now, darlings. This is going in the scrapbook" Rarity cooed as she came in with a camera and had the three pose together as it flashed, marking the end of another night of passion and romance between their circle of friends.
