Twilight waited impatiently for Rainbow Dash to arrive to her library, the cyan Pegasus had told her that she would visit her today and Twilight was excited to see her, ever since becoming a princess, Twilight had been very busy and had not been in Ponyville very often, meaning she didn't have a chance to visit her friends.
Unfortunately, when she did see her friends, they seemed distant, likely because of her new status as Equestrian royalty. Twilight had very much hoped that they would not be intimidated by her new position as a princess and an Alicorn, but her friends now seemed to be separated by an uncrossable void.
All except for Rainbow Dash, the Pegasus had not abandoned her when all her other friends had left her, and over the proceeding months they had drifted ever closer. Rainbow even held an extreme fascination for Twilight's new wings, although Twilight herself had not discovered exactly why they fascinated her so much.
Twilight was knocked out of her reverie by a tapping on her door, excited to see if her friend had arrived, she quickly went to find out. Opening the door, Twilight found it was indeed Rainbow Dash who awaited her and instantly enveloped her friend in a hug.
"Oh, Rainbow! It's so good to see you! Come in! We can read the new Daring Doo book together!" Twilight said excitedly, glad that her only remaining friend had come to visit her and looking forward to a break from her tedious duties as a Princess of Equestria.
"Eh, sure, we can do that." Rainbow gave a slight glance to Twilight's wings, Twilight was too caught up in the excitement of seeing her friend again and didn't pay much attention to the glance, dismissing it as unimportant.
Making her way over to one of the many bookshelves that were contained within the library, Twilight began to search for the latest Daring Doo book.
A sudden weight upon her back had Twilight give a slight jump from surprise. Turning back, she saw that Rainbow had placed herself on her back and was starting to nuzzle her wing.
"R-Rainbow, wha-." Twilight was cut off as Rainbow gave her wing a lick, Twilight was unable to continue as a new feeling spread throughout her body. She had read about Pegasi having sensitive wings but was naturally unable to experience it until now.
Twilight didn't speak as Rainbow continued her ministrations of her wing, slowly, she felt her wings begin to rise as Rainbow continued to lick and nuzzle them. Twilight became lost in the feeling until eventually, Rainbow was forced off her back from her rising wings.
Turning around, Twilight could see Rainbow looking at her expectantly, moving in to kiss her, Twilight could feel Rainbow's hot breath on her briefly before she locked lips with her. As she cautiously and amateurishly mashed lips with her, she could feel Rainbow attempt to gain access to her mouth, slowly parting her lips, she accepted Rainbow's tongue into her mouth and enjoyed the new sensation of Rainbow's tongue as it explored it's surroundings.
A muffled garble came from Twilight as Rainbow's seemingly experienced tongue made it's way further into her mouth, before it began to tease her own into action. Sloppily trying to match Rainbow's movements, resulting in a pleased sigh coming from the Pegasus.
Taking her focus away fro Rainbow for a moment, Twilight saw that the Pegasus was enjoying herself, her wings having reached about the same height as Twilight's.
Disengaging herself from Rainbow, she pulled out of the kiss, leaving a trail of saliva between them. Twilight began to move closer to the pegasus wings.
"Twi-." The Pegasus was cut off as Twilight sensually placed a hoof over her mouth. She gave an experimental lick of Rainbow's wing and was delighted to feel the Pegasus shuddering in response. Feeling emboldened, Twilight continued her ministration of Rainbow's wing. Since she had two wings and didn't want to seem to be favoring one, Twilight lightly dragged her hoof across the other wing in an effort to split her attention.
Rainbow had not simply waited passively for Twilight and Twilight was surprised to feel that in her compromising position, Rainbow had managed to nudge herself closer to Twilight's hind quarters. As Rainbow managed to leverage herself into position, Twilight was pushed slightly as Rainbow took the last bit of distance, Twilight's discomfort quickly changed to pleasure despite the awkward position as she felt Rainbow's seemingly experienced tongue work its way around her outer folds. Gasping in pleasure, Twilight tried to keep up her end and Redoubled her efforts on Rainbow's wings.
Twilight slowly pushed Rainbow on her side, receiving a small whine of protest as they were temporarily separated, taking the initiative. Pulling up her magic, she gently flipped Rainbow on her back. Twilight had expected Rainbow's wings to get in the way, but was surprised to find them flattening against the ground.
Positioning herself atop Rainbow, she gave her another passionate kiss, slipping her tongue inside, she sloshed it around in an effort to replicate Rainbow's movements. Rainbow, feeling Twilight's attempts, took over and lead Twilight through the movements. As their tongues swirled, Twilight got lost in the pleasure and began to grind herself against Rainbow. Not to be outdone, The Pegasus responded in kind, doing her best to match Twilight's movements. Muffled groans came from the pair as they mindlessly ground against each other. As their juices intermingled in a puddle on the floor, Twilight regained enough presence of mind to turn herself around.
Positioning her muzzle in Rainbow's snatch, Twilight felt the Pegasus's eagerness, wasting no time, Twilight began to gently probe the mare's slit with her tongue, causing Rainbow to buck her hips into Twilight's muzzle in an effort to get her to keep at it, along with a fresh gush of juices soaking Twilight's face thoroughly.
On the other side, Rainbow was familiarizing herself with Twilight's previously untouched hole. Enveloping her hind with her hooves, she dragged Twilight's plot down to meet her. Burying her face into Twilight, she began to delve her tongue deep into Twilight, Delighting in the sensation of her slick insides pulsating when she dragged her tongue against a particularly sensitive spot. As she focused her efforts on Twilight's clit, She could hear the mare gasp in pleasure, so lost in it that she was unable to continue her work on Rainbow.
While deterred, Rainbow was certain that she could quickly bring Twilight to the bring and beyond. Forcing herself even further into Twilight, she continued to lick all around, occaisonally stopping to move and nibble slightly on Twilight's sensitive clit, each time hearing Twilight's moans increasing in length and volume.
Rainbow went unattended as Twilight quickly approached climax, feeling Twilight's walls pulsate, she increased her efforts, suddenly, Twilight let out her largest moan yet and began to frantically buck against Rainbow's face. The Pegasus felt Twilight's juices spray against her face as Twilight rode out her orgasm and drenching her Rainbow's face in the process.
"Rainbow..." Twilight said, faintly, as her voice was still hoarse from her enthusiastic response to the Pegasus's ministrations." That was... great."
Rainbow was less than impressed, slightly irritated that she had not gotten off, she made her displeasure know to Twilight.
"You gonna leave me all alone here Twilight?" Rainbow said, Twilight looking bashful as she realized that Rainbow had not enjoyed herself quite as much.
"Oh.. Of course." Putting on a sultry look, Twilight kissed Rainbow, tasting her own juices in her mouth, she continued this for a moment before disengaging and moving further down the Pegasus until she was once again level with her pussy. Feeling adventurous, Twilight slowly inserted her horn into Rainbow, who gasped in shock as it parted her tunnel.
Emboldened by Rainbow's acceptance, Twilight slowly pushed her horn in, eased by copious amounts of fluid that had already built up from Rainbow's anticipation and Twilight's earlier work before bringing it out, building a steady rhythm as Rainbow made her enjoyment clear, her panting egging Twilight on as she continued, although slightly worried that a stray movement from Rainbow could end quite badly, the element of danger added to her enjoyment of it.
Moving ever faster, Twilight slowly added a small amount of magic to the mix, channeled through her horn, she attempted to speed Rainbow along by allowing her magic to vibrate lightly against her horn. Rainbow's moans increased and Twilight felt that the mare would soon be done and increased her pace yet again.
Rainbow moaned ever louder as Twilight felt her walls clamp down on her horn, she stopped her magic as Rainbow reached climax, her walls crushing against Twilight's horn for a few moments before she settled down with heavy breaths. Seeing she was done, Twilight pulled her horn, which was now drenched in Rainbow's juices, out of the mare.
Drained from the ordeal, Twilight dragged herself up to Rainbow and snuggled against her. Rainbow was accepting as Twilight pulled her closer as they both rested from what they had done. Eventually drifting off to sleep upon the floor.
