Complications

Celestia was sensually rubbing her sister's marehood while Luna moaned out in pleasure. The older sister's touch on the younger of the two was driving the moon goddess crazy. Celestia's tongue was passionately lapping away at Luna's nipple stimulating the sensitive flesh.

Luna's moans began escalating as her body responded to her sister's caresses. The nipples were erect, the slick tongue lapping away at them. The slit was leaking fluids and drenching the hoof that was invading it. Luna's mind got hazy with arousal and her senses faded.

Celestia was enjoying herself, her tongue flicking away at Luna's nipples in delight. Her mouth started circling one of the foal feeders and she suckled on it as if drawing milk. Celestia's hoof continued to slide itself in deeper into the sopping cunt of her lovely sister as she suckled away tenderly.

Luna's legs started bucking from the sudden jolts of pleasure, she was careful not to hit her sister's face. It was becoming too much pleasure for Luna; she was about to explode in ecstasy. Her body's frantic spasms was signaling her imminent orgasm and warned Celestia with seconds to spare.

Celestia was grinning at her sister's display. She was going to finish her sister off with her slick tongue. "Mmm' I can't wait to devour your scrumptious pussy Luna." She huskily groaned.

Luna was wide eyed and begged, "Please sister, I am already close just finish me off."

Celestia slid her hoof out and chuckled, "don't worry sister, I shall dive right in."

She sniffed her sister's sopping hole and began tentatively licking it, watching her sister's legs buck from the sensation. She held her sister's hind legs down and began feasting away at Luna's slick nethers, enchanted by her exotic flavor. Her tongue slid deep inside and massaged the inner walls of her sister's love tunnel, slurping the juices. While doing so adding to the intensity of her actions.

Luna couldn't hold back anymore, she was at the edge and needed to release. "I am... cumming!" She lewdly howled. Her body arched as her exotic essence shot out violently into her sister's welcoming mouth. The moon goddess felt her heart stop for a second at the intensity of her orgasm. She panted furiously as she began coming to.

Celestia greedily drank her sister's nectar enjoying the taste of Luna's essence. The strong and bittersweet taste was causing Celestia to engorge herself on it. She finished drinking what was offered and, lapped away at her sister's nethers to clean it of the tasty juices.

Luna was breathing heavily when she felt her sister snuggle up to her and smiling wide. "Oh Celestia, if only you had the courage to do this in the real world," Luna sadly commented.

Celestia wasn't aware of what that meant until the walls of the room de-materialized and the empty abyss of her dreamscape revealed themselves.

____________________________________________________________

Celestia's eyes shot open and was about to panic from how real the dream seemed. She looked around and noticed she was still in her bed with Luna snuggled right beside her. Unfortunately though Celestia's hind legs and nethers were covered in her own marecum and, she was freaking out.

Luna was blissfully unaware of her sister's current state and continued sleeping. Her body shifted; being uncomfortable from her coat's wetness, in doing so she almost rolled off the bed. Luna didn't feel the warmth she felt earlier and caused her body to stir and wake.

Celestia's panic grew as she was sure she would have to do something to distract her sister when Luna came to. It was going to be difficult explaining the damp sheets but, if she couldn't it would make things awkward for them.

Luna's yawn and blinking eyes gave evidence to her being awake. She was slowly coming to and was feeling rather grumpy. "Can't a mare get some sleep around here?" She angrily howled.

Celestia chuckled and gently kissed her sister's head affectionately, "I’m sorry you couldn't sleep my dear sister."

Luna blushed at the tenderness of her older sister and beamed. "It's alright. I guess I should head off to my own room ..." she sniffed the air due to the pungent musk that filled it. "Sister... what is that smell?"

Shining Armor wasn't a happy stallion at all. His anger grew with each second that passed. He was trying to have a private moment with his wife and sister but unfortunately for him, the group of friends that his sister usually ran around with decided to all meet up at the library, for some reason or another.

Rainbow Dash had to get to the library to ask Twilight about gender changing spells. she wanted to impregnate Fluttershy and felt it would be best doing it the natural way. Magical pregnancies could lead to potential risks and chemicals could have a longer lasting effect than wanted. She resolved the only way to make Fluttershy a real mother was to become a stallion and rut her marefriend good.

Fluttershy was of course accompanying Rainbow Dash to calm the fears of the group about their decision. The group had all thought Fluttershy was forcing the issue, since she and Dash had pulled a prank on them earlier. Because the prank went off without a hitch, it caused a side effect of Fluttershy seriously wanting a foal.

Applejack was at the library to get away from her brother before she did something she would regret. She loved her brother dearly but his attitude was uncalled for and unneeded. She decided to just walk away from the argument before it got too heated. She was with Rarity enjoying her time and continued wanting that peaceful moment, so they went to the library to get away from it all.

Rarity was with Applejack and originally came to relax and enjoy a quiet atmosphere. Though she found juicy gossip in the making, with Shining Armor's inability to impregnate Cadence and Rainbow Dash wanting to be a stallion to give Fluttershy a foal. She was a happy pony at the moment.

Twilight was being mentally strained by the requests of her fellow ponies. They each wanted something and it was driving her insane. She decided to prioritize her tasks and help her brother first, so she could help them have a foal. "Alright listen up, Rainbow Dash; you and Fluttershy will have to wait about your requests since Shining got here first and he has a kingdom to run." She calmly instructed.

Rainbow Dash nodded and lounged about with a Daring Do book in her hoof and quietly began reading it while her marefriend snuggled with her. "Alright egghead, just don't take too long," she nonchalantly replied.

Shining Armor was not amused at having all these ponies know about his circumstance and, was afraid of having to do something embarrassing to find out if it's his seed that isn't functioning or his wife's eggs are barren. "So Twiley, what exactly will you be doing to find out why Cadence hasn't been able to get pregnant?" He hesitantly asked.

Twilight blushed and fiddled her hooves together before awkwardly announcing, "well, I will have to run a series of tests... and maybe... if it comes to it... watch you two make love."

The silence in that room was stagnant, not a single noise was made until the convenient entrance of Spike was made.

"Hey everypony what's going on?" Spike excitedly asked. He himself was having a good day after they all split up to do their own thing. He was hanging out with Sweetie Belle and enjoyed a nice date with her before seeing her home. He even snuck in a kiss and felt like a real dragon.

Rarity was not going to be party to such uncouth things and decided it would be best for her to get back to work. She had a business to run still, and the customers weren't going to make their own outfits. "Well I would love to stay and chat darlings but I have orders to complete, Applejack if you wish to come with and help that would be fabulous."

Applejack got the gist of her statement and followed suit, "Yeah sure, I reckon I can help ya sugar-cube." She followed Rarity out the door, leaving the library to escape the uncomfortable mess.

Fluttershy nudged Rainbow Dash and whispered something, inaudible to the rest of the group, inside her ear. Rainbow Dash wasn't happy with being ordered around but, felt this one time it was the wisest choice. Fluttershy knew that it would be hard for the regal ponies to have to be tested in public view, so she decided to aid their privacy. "Well Rainbow Dash and I are going to the park, if anypony cares to join us that’s where we will be."

When the two pegasi mares left, it was still silent as the group of ponies were hoping that somepony would find something for Spike to do. Pinkie Pie felt obligated since the others didn't invite the baby dragon and that left Pinkie angry. She had no ill will towards Spike, she just didn't want to leave her marefriend alone to do some freaky procedures.

Twilight looked at Pinkie Pie and frowned, "Please Pinkie, can you take Spike to the bakery and wait for me to finish?" She sadly requested.

Pinkie Pie was about to refuse but knew that she couldn't, "Sure Twilight I’ll take Spike, and we will bake delicious treats for you all." Her fake smile fooled no one except Spike. "Come on Spike," She gently ordered. She started slowly leaving with Spike in tow.

With all the ponies gone the private testing could begin...

Celestia was finally alone after her near tragic moment with her sister. She had carefully orchestrated a lie that was convincing enough for anypony to buy. "Silly Luna, thinking it was just sweat... well now I can read that darn book... though I should do something about the smell... later... I must read."

She began lifting the accursed literature and opened it again and looked for the spot she left off. before she continued reading the enticing erotic book...

____________________________________________________________

Celestia's sexual caresses stirred Luna from her slumber. The alert mare now aware of the incestuous desires of her older sister. "Tia... what ... are you... doing?" She hesitantly asked while her nethers were being rubbed with a hoof. Luna's ability to think was hindered by the pleasure being received.

"Oh sister... you have awoken... don't try stopping me, because I need this," Celestia darkly commanded.

Luna was unsure of what to do, she couldn't decide whether to accept it or attack and fight back. "Please stop Tia, I love you but I won't let you do this." She shakily warned.

____________________________________________________________

"Would Luna really fight back if I was to seduce her... hmmm." Celestia spoke softly before returning to her reading...

____________________________________________________________

Celestia chuckled, "What shall you do about it, my dear sister? Your cunt is dripping and you aren't resisting in the slightest."

Luna was silent and contemplated her next move, she was either destined to battle her sister or be shamed with incest. "Celestia for the last time I am warning you, let me go or I shall have to hurt you..." Luna hesitantly spoke. Her tears started leaking at the thought of having to hurt her older sister.

Celestia grew tired of the threats and shoved her hoof, deep into her sister's drenched marehood as a response to her warning. She began pumping her hoof into her sister's warm cavern and, felt delighted when she heard some moans as her sister's resistance fade. "See I knew you’d love it, you almost scared me for a second dear sister." Celestia shyly admitted.

Luna's resistance had died as the pleasure overcame her will. Her turmoil had been pushed back by sheer joy. She began moaning as the pleasure continued building up. Her body felt like it was floating and her mind was fogged, she had barely any cognizance in her as she was being sexually stimulated.

Celestia popped her hoof out of her sister's drenched cunt and licked it lewdly, "I could tell you were getting close and I wanted to not spoil our first time with you cumming so fast." She huskily explained before sliding lips towards her sisters and pressed them together.

Luna whimpered into the kiss and felt a bit miffed about being teased, the feeling went away when she was eagerly accepting her sister's passionate kisses. Luna felt Celestia's tongue trying to gain entryway into her mouth and she submissively opened it. Her mouth was invaded by the tongue, blushing at how good it felt to make out with her sister.

Celestia's slick appendage ravaged her sister's mouth. Celestia moaned into the kiss as she began rubbing her sister's tongue with her own. Celestia's tail began gently wrapping around Luna's and tugged on it, wanting to claim more of her sister.

When the need for air became apparent the two mares released their erotic kiss, the saliva slowly stretched and broke causing Luna to moan out. Celestia slowly licked her way up to her sister's horn and began teasing it by gently kissing the base.

Luna was tired of being the dominated one and fought back, "No!... I want to lick your horn sister... let me give you a horn job." She huskily requested.

Celestia was already hoofing her royal pussy and losing her mind as she read the passages from the book. "I can't believe Twilight actually wrote this... I need to stop for now and shower before the stench permanently attaches itself to me... though, I can't stop reading this book..." She was going to keep reading, but she was becoming light headed from the pungent odor in the room.

She cursed herself and decided she would take a light bath and go back to reading the maddening work of her student's mind. She began walking to the bathroom before a brilliant thought came into her head, "Why not invite Luna? She and I have bathed together before... it's not suspicious to invite her to bathe... I just have to play it cool." Celestia ignorantly decided.

Twilight was working hard trying to figure out why her brother and sister in law were having issues procreating. She had taken samples of their fluids and other unsightly material for the prospect of learning a possible hindrance to their foal making plan. She had to get through the awkwardness and stay objective, for the sake of science!

After performing countless tests she had no answer still as to why they weren't able to breed successfully. She was going to give up but had some few theories she wanted to try out. "Well I have come back with inconclusive results and that means things are about to become weird for all of us." Twilight hesitantly reported.

Shining Armor was not going to have sex in front of his little sister, "Twiley is there any other way besides you watching us having sex to figure out what's wrong?" He grimly asked.

Twilight looked down, unable to meet her brother's gaze. "No... it's either I watch or somepony else does, but if it isn't something physical or chemical then it has to be something mental... and that means I would have to see how you to make love to understand why your sperm or her eggs are refusing to work."

Shining Armor sighed, "Fine... when can we start?" He inquisitively grumbled.

Cadence nuzzled her husband and spoke up, "We can begin now. Shining... I hate to admit this but all this talk of somepony watching us make love has me aroused, and I need your big dick to sate my pussy."

Shining Armor never felt more aroused than that moment. He forgot all about his sister being in the room, and began to gently lay his wife down on his sister's bed "Well, if you’re that eager I guess I can't refuse." His body was getting in position and felt ready to rut Cadence.

Just before Shining Armor's cock could enter the receptive marehood of Cadence, Twilight decided to interrupt them; having figured out what is wrong with their form. "Hey!... You guys... where is the foreplay?" She called out.

Shining Armor was confused, "What's foreplay?" He quickly asked.

Cadence was miffed at not being given the dick, "Yeah Twilight... what is it?"

Twilight knew that her brother was a sexually repressed goody goody, and now knowing Cadence was too meant they had to learn something that she was not willing to teach. "Well... I can't just explain it and I wouldn't feel right showing you it... but I know somepony who could teach you all about foreplay..." She hesitantly explained.

Shining Armor wasn't sure if he liked the idea but he was willing to do anything to help his wife become happy again. "So, who is this pony?"

"It's... Rainbow Dash."
