Curious intimacy

High up in the Canterlot towers sat Princess Luna gazing over a book. The sun outside hung high, and Celestia admired the result of her daily responsibility whilst watching from the balcony over Equestria itself. The Solar Princess decided to check up on her dear sister. As she headed back inside she smirked a little knowing that Luna had once again been on another possible midnight feast after raising the moon, the evidence all too clear from Luna’s slight weight gain.

Luna flipped another page of her book and began reading a section titled “Human reproduction system.” Luna blushed a little, checking over the room before giving the all clear. This book she had borrowed from Twilight Sparkle was rather handy for this situation, however. Especially with what she had been working on within one of the Canterlot chambers. Luna began to read up towards the process of copulation. Again she blushed and felt a strong pang in her nethers.

Luna tensed up and felt warm fluids drip between her flanks. She couldn’t recall the last time she had relieved herself with one of the many well-hung guards of the castle. Right now, she was thinking very differently. Luna had become very curious about humans over the past few months, they were rare visitors to Equestria, and out of them all humans were an even bigger rarity. Riqsué thoughts began to cloud Luna’s mind, distracting her from her crude research. She eyed over the diagram of a naked human male; the first thing she noticed of course was their lack of ‘size’ compared to stallions, but Luna still wasn’t put off.

Again her warm throbbing nethers ached for attention. Luna covered her wide derriere with her tail, and took another bite of cake, levitating the slice with her magic. She allowed the rich, creamy flavours to satisfy her tongue, and soon enough Luna was able to read again.

“Hello dear Sister!” Luna almost choked and blushed full red. She swallowed the morsel of cake quickly as possible whilst remembering to cover her shame. “Reading about humans again?” Celestia questioned.

“If I were you I’d go and check how things are going, it’s been awhile.” Luna simply nodded wishing for Celestia to leave. “That is if you can still fit through the door!” Celestia giggled giving her sister’s rear a sudden prod. Luna almost jumped out of her coat and stood to attention facing her rump away from her sister’s teasing eyes.

“Thou should be aware of the procedures we are taking to reduce the mass of our body!” Luna reacted defensively.

“Indeed, all the fat has gone to your end. And you were welcome to my cake also! I hope it tasted good!” Celestia added.

“We are aware of the sarcasm thou cast upon thine ears!” Luna huffed. “However thou shalt have been more wary of leaving such a delectable treat at such a vulnerable reach!” Luna grinned and licked her lips.

“But what will he think of your huge butt being in the way?” Celestia giggled childishly, but Luna returned fire coarsely.

“Thou insult our royal posterior, yet thou shalt be aware of thyself!”

“Oh, I’ve been watching my weight, Dear Sister.” Celestia smiled, but she quickly snuck a look back at herself.

“Doth thou wish to continue interrupting our study?” Luna rolled her eyes.

“Okay Sister, I’ll leave you to it. Feel free to help yourself to more cake!” Celestia trotted off with a hearty laugh. Luna gritted her teeth, but she soon resumed reading.

“This resource of education is most entirely descriptive!” Luna blushed red hot feeling another warm trickle. She could literally feel her soaked wet insides clenching furiously, and her sensitive clit had slightly swollen, desperate to be rubbed off. Luna knew a simple wave of the hoof wouldn’t satisfy her demanding needs.

She had to take care of this with him.

Checking at first to ensure there were no prying eyes casting their way down the stellar corridor, Luna levitated the book with her whilst heading down to the chambers. With each step Luna took she could feel her full round flanks rubbing dangerously close to her nethers. Knowing her coat was already stained with her fluids, Luna kept her rear hidden with her starry tail. Upon her descent downstairs Luna could suddenly hear hoofsteps approaching in the opposite direction. Luna halted immediately, praying that she wasn’t blushing as a robust guard climbed the stairway.

“Princess Luna! After you.” The guard gave enough space up for Luna to pass, but Luna felt far too ashamed at this moment; especially with where she was headed.

“Y-You may pass.” Luna instructed.

“But Princess I insist!”

“Thou shall pass!” Luna snapped in her Canterlot voice. The guard shrugged a little and made his way up, however upon passing he felt his cold armour brush against Luna’s wide flank. The Princess held in a yelp as she immediately continued her descent.

After dodging another Royal Guard, Luna finally made it to the chambers. It felt a lot colder down here but Luna didn’t mind. She found the right door and knocked twice on the wood before entering.

The door swung inwards to your surprise. Another visit hadn’t been expected but here she was again.

“Arise, human subject!” Luna called. She was greeted by your formal welcoming display as she locked the heavy door shut. Just for a second a brief gaze at Luna’s face gave away all her royal beauty. Of all the ponies seen here she was definitely the eye catcher. A beautiful Lunar Princess at that.

“Art thou troubled?” Luna asked after catching your stare. Her alluring blue eyeshade only gave her more of a human-like attractiveness. The pure symmetry of her face was amazing. There were times where she barely even looked like a pony. Luna cleared her throat and set the book down on a nearby table. This chamber room unlike the others had been well looked after. It felt like a bedroom to you at least. Even the warm carpet rubbing the soles of your feet felt extremely welcoming.

“Art thou happy with the current settings and conditions?” Luna turned her attention to you once again, and she was reassured by a firm nod. After all it was voluntary that you decided to help Luna in her study of humans. What was that book on the table though? Not only that, but the bright red carpet had several dark spots where Luna walked.

Princess Luna paused and hesitated. Of course her body hadn’t forgotten the frustrating sexual strain it had been enduring as much as her mind had been. Again the sensual throbbing returned to her lower region as Luna tried to compose herself. She wondered if such an action would bring trouble, but right now it mattered not. Duties were duties.

“Subject, we ask a favour of thee.” Luna paused. “U-Upon the study of the homosapien race we demand you perform a duty for us! Shalt thou accept we will be most willing to reward thy favours of thou most dearly.”

What was Luna on about? She was hard to comprehend. Luna seemed to come closer to you. So close in fact that her nose almost bumped against yours. Luna wasn’t too short, but you weren’t much of a giant yourself. Again that divine beauty of hers greeted your eyes up close. Luna had a rich scent of summer flowers. Her green eyes seemed to glow as she hesitated to speak, and her soft looking blue lips quivered slightly

“Art thou willing to accept?” Luna’s tone sounded less firm and more sensual this time. She blinked slowly, and even her smile was visible which was a rare thing to see.

Another nod made Luna smile even wider.

“Prepare thy mouth.” Those were Luna’s words before she pressed her lips against yours. It was a soft kiss, nothing too unfamiliar, but it felt so warm and loving. Luna pulled back slowly blinking her eyes open. The look of surprise from you made her question her actions. Luna hesitated but pressed her lips to yours again, and that’s when she felt a hand stroking down her neck. It was as if a switched had been turned on inside Luna’s mind. This felt so strange, yet so intimate and pleasing.

Now that she felt accepted by her subject; Luna pressed her lips further. This kiss felt strangely humanlike, much like her lips themselves. Their dainty touch against your lips made impulses react, it was hard to tell whether you were kissing Luna or a celebrity model. Again Luna slowly retreated, and her face was flushed red.

“T-Thou art understanding of thy needs?” Luna questioned. “We wish to continue, but more like the humans do. Please submit thy tongue to our mouth.” At least some of this was comprehensible. Luna came forth for another kiss, and now she was getting the hang of things. It was then that you felt something thick, warm and wet pressing to your lips. Another act on impulse allowed Luna’s tongue to slip inside. Hers was slightly rough, but not too irritable. A spark flew from Luna’s horn upon feeling your tongue against hers.

It was unclear why she wanted this, but one thing was for sure. Luna was stunningly beautiful in every way, shape and form. From when your eyes closed it was a whole new feeling. Her warm, thick tongue caressing over your thinner human counterpart. The feeling of love grew between you both as Luna felt that hand stroke her neck. You’d felt like telling her before of your curiosity, but feared she’d cast you away. That clearly wasn’t the situation now, however. Luna pressed back much further until she heard a loud thud, and the next thing she knew she found herself on top of her human.

Luna closed her eyes again embracing your presence against her. She felt your human hands upon her wings gently stroking across. A slight breeze wafted the room as Luna’s wings sharply unfolded out of arousal. Her sexually irritating nethers had calmed down a little, seemingly satisfied with the current situation. Luna’s tongue drove against your taste buds before the pink muscles danced slowly in each other’s mouths. Luna was held against your body, and her eyes popped open as she felt something hard poking against her underbelly.

The kiss ended with a bridge of saliva between tongues. Luna’s eyes were open halfway as her beautiful blue mane curled down her face.

“Thou seems to find this most arousing. We are pleased with your cooperation. Perhaps thou woul-” Luna felt your warm tongue slide into her mouth again. Her eyes began to close, but it was only a brief kiss. Luna looked upon you with curiosity and was reminded of what lay between your legs. Her breaths came short falling upon your face as stares of curious lust pierced each others eyes.

“We demand thou remove thy cloths upon your body!” Luna blushed slightly, but she watched you strip slowly down to nothingness as you wondered what would become next of this slightly awkward situation. Most ponies here were casually without clothing, but of course this didn’t apply to humans back home; nor was it the norm. The concentration of red in Luna’s face deepened as she witnessed her first human penis. Standing erect with a few veins visible, it was of average length.

To give the Beautiful Princess of the Night easier access you decided to sit legs apart on the warm carpet floor. Luna had read from several books including Twilight Sparkle’s borrowed one which was probably why she was blushing now. Luna touched a hoof briefly to your member. Luckily her royal metal horseshoes were warm rather than icy cold. Luna sat before you, and she used both hooves to slide down the foreskin revealing the throbbing, wide head of your phallus.

She sat mouth agape, and her tongue moved about inside. Luna gave you a sensual stare as she rubbed her hooves up and down your blood-filled appendage.

“I wish to sample it in my mouth!” Luna held a hoof to her shocked expression. Never had she blurted out like that before, especially without the royal We. Luna mentally scolded her sudden informal outburst, but she met with your warm smile taking it as a sign that everything was okay. Luna rested on her belly, and she placed her hooves on either side of your waist. Luna shuffled closer with her mouth nearing your shaft, and suddenly a wet sensation crawled up your dick. It was surprising at first yet intensely stimulating. Luna held back the foreskin with her hooves again, and she began to lick your sensitive tip.

The penis moved between her hooves as she licked all around, going up and down with her tongue. The taste and feel was different to a stallion’s, but much easier to handle. Luna briefly kissed the tip with her lips, looking up to see your reaction. Luna continued after seeing the arousal in your eyes as she opened her mouth, and swallowed your cock whole. Luna had forgotten that a stallion's penis length wasn’t equal to that of a human. She had literally engulfed the entirety of your cock inside her mouth. Her warm lips pressed into your sack, and as if that didn’t feel good enough already her tongue had begun to move across your wet dick.

Little wet noises could be heard from Luna’s mouth as her tongue ran along the base of your shaft. It felt extremely slimy and hot inside, the two most incredible sensations creating a mix of outstanding pleasure. Luna kept her eyes closed as her tongue explored her first human and his sensitive parts. Her thick tongue pressed your phallus against the roof of her mouth, and her lips tightened as she began to suck back and forth.

Luna heard a loud grunt meaning she knew she was doing the right thing. Luna sucked extra hard upon reaching the tip, and let it slide out with a loud wet pop. Luna watched your member spring upwards painted in a coat of warm saliva. She took it welcomingly in her mouth again, and she began to suck repeatedly with a little more force. Another gasp fell upon her ears as Luna tasted and measured your length in her mouth. She loved the occasional throb it gave off as pleasure coursed down every nerve in your member.

Luna sucked your slick cock deeper down her mouth. She even took in your sack, running her tongue along the shaven flesh, and rubbed her lips hard against your shaft as she pulled back up, sucking like a vacuum. Luna caught her breath as your dick popped out between her plump lips, and rested against her face.

“You seem most pleased, human!” Luna had forgotten her formal tongue again, however now was not the time to worry about formalities. Especially with what she was doing with you. “We are pleased you are enjoying this.” Luna looked up at you with that same sensual stare. She tongued your shaft and sucked it inside her mouth again. Luna could be heard slurping slightly as her head bobbed back and forth much faster now.

Her dripping fluids however reminded her of what she had been putting off. By now a puddle of fluids had stained the carpet beneath her wide rump, and it gave off a powerful scent. As Luna’s hungry mouth stimulated your throbbing cock; the powerful scent entered your nostrils. At first it was a hazy feeling, but then sweat dotted down your chest. Luna felt a hand stroking her face, and it moved up to her ear giving rewarding scratches. Luna heard groan after groan, and even she hummed quietly as she suckled your wet phallus. The musky smell grew stronger in the room further enticing your animal instincts.

Luna pulled up from your dick knowing that soon you’d possibly expel seed upon her face. Luna wasn’t sure but she’d rather not ruin the moment.

“We must ask of thee another favour!” Luna panted desperately as her pussy twitched harder. The mouth certainly wasn’t enough, but she noticed you got the message. Luna rolled onto her back, and she rudely parted her legs without much care. By now her entire lower region was wet with juices everywhere. Luna watched as you gazed upon her thick, wet labia and her saturated flesh where her opening lay just begging to be filled by male flesh. Her swollen clit throbbed between her labia as she panted louder. Just the inviting sight of her pussy was enough to make you cum already from imagining how it’d feel in there.

“We wish to mate with you, human; we feel it is a necessary experience to expand our knowledge on your species!” Luna may have spoken the truth, but she could barely hide her lust behind her excuse. More clear fluids leaked between Luna’s twitching labia as she tried to put her tongue back in her mouth.

“Come human, we demand you mate with us. Expand our knowledge on humankind!” As if Luna needed to say it twice. The feelings of lust and curiosity rose ever higher. Luna gasped as she felt fingers rubbing against her slimy flesh. Her pussy lips were parted by human hands as she watched you gaze into her fleshy opening. Strings of Luna’s pussy juice lined across the insides of her pink, puffy flesh. Another throb below enticed your member and Luna suddenly felt an entire hand slide inside her hot, wet passage.

It felt so slimy and warm inside as your fingers rubbed across her wet insides. Luna’s breaths became short as your hand explored inside her with ease. A sultry moan passed her lips as she felt the hand go in further up to your elbow. Luna felt your fingers dancing across her inner flesh, but it wasn’t enough to satisfy her. “Remove thy arm and proceed with copulation!” Luna managed to sound demanding despite her state of arousal.

Just to deliver more pleasure Luna felt your hand ball into a fist as it slid out slowly glistening with fluids. More secretions stained the carpet as Luna grew impatient. She watched as your lubed hand covered your dick in the same stuff. A shadow grew over Luna as you climbed over her, and her legs parted further allowing you to park your waist between. Luna gazed into your eyes, and she felt something warm prod between her pussy lips below. Luna wrapped her forelegs around you, and she gasped as she felt her first human penis penetrate and make contact inside her.

Luna’s insides were so wet and hot that it almost felt numbing as your shaft slid inside. Her breaths fell shorter, and she felt your body against hers. Luna’s saturated inner flesh gripped around the head of your phallus, engulfing the entirety of your length as it penetrated as far as possible. Luna snuggled you closer, but she seemed to be waiting for something.

“We were expecting deeper pleasure, human. Is this the full extent of your penetrative capabilities?” Luna noticed the blushing and embarrassment on your face, however she reassuringly smiled back. “Not to worry human, I am to blame. I shall remedy this!” Luna instructed you to pull out, and lashings of pussy juices coated your dick. Her horn began to glow casting an aura around your shaft.

“We often practise this magic in secret with the guards!” Luna watched and smiled as the change started to happen. A weird throbbing sensation spread through your groin, and before you knew it a growth started to happen. Luna observed as your size grew long and thick. The veins grew bigger, and at first a light-headed sensation passed. The thick phallus continued growing ever longer filling with more blood. Luna licked her lips lustfully watching your tool extend under her influence of magic. The foreskin was fully stretched out, and it appeared slightly darker; looking almost like a stallion’s cock

Luna gazed at your exaggerated horse-like length and thickness stretching over the slit of her pussy. The thought of having this back at home seemed cool, but would probably be very troublesome. It felt quite heavy in the hand also.

Luna grinned and spread her hind legs again invitingly. She watched as you held your thick member just about getting your fingers around it. The thick head parted Luna’s labia, and as it penetrated she felt her insides being spread apart. Luna moaned loudly as she felt the gargantuan tool snake inside her eager pussy. Her silky insides seized around your wide girth, and Luna hugged you close again as she felt the thick tip resting deep inside her.

“We are waiting, human.” Luna grinned and soon enough she felt your thick schlong sliding backwards. Fluids spilled from Luna’s flooded royal cunt as your raging hard-on retracted before being shoved back inside. The sensation was absolutely amazing, and her femness engulfed your thick girth with every thrust.

“Ahh human we are enjoying this new experience. Your manhood satisfies my needs well!” Luna definitely felt different having sex with a human. The way she felt your hips thrust into her, the way she felt you holding her, and the eye-piercing gaze of lust she shared with you. “I feel most dirty mating with you, human!” Luna gasped and moaned sexily off her own accord as she let go.

“Yes, fuck your Princess!” Luna’s filthy words spilled carelessly from her mouth as she felt your thick rod spearing her insides, but her language was only more of a turn-on. This was no longer curiosity but lust for a human. Luna hugged you closer, parting her lips as her tongue rose upwards. She waited for you to lower your mouth and she held your head down, pressing her lips against yours.

Luna’s thick tongue rubbed around harder, poking the mouth of her partner. She briefly opened her eyes to gaze at you as she felt another hard thrust between her legs as your veiny, thick cock spread her open. Luna felt your warm shaft rest again as the hot, passionate kissing continued. A hand stroked down her side as lips parted and wet, warm tongues rubbed against each other. It felt so unreal yet so satisfying with Luna, her aura caught you in a moment of pure intimacy with no care for difference in species whatsoever.

Luna stared back sexily wishing to feel the thick phallus lodged deep in her crevice moving again. The two tongues parted as Luna felt your hot breath on her face. She gave you that tempting stare, and she began to move her hips into you. Luna hummed lovingly feeling that big pecker sliding out between her mounds. She felt it rubbing against her labia going across her throbbing bud also. Luna’s muscles tensed as the warm, slimy sensation tantalized her clit. Luna opened her mouth wide, and took in the much thicker helmet of your girth. She tasted her own juices licking and sucking your pride, showing her adoration for your loving member.

“Forgive my lustful intentions human, penetrate us again now!” Luna’s sexy demands were fulfilled, and she grimaced as she felt your slick, long hard-on spreading her open again. Luna constricted the throbbing meat between her soft, wet, hot folds. She held you down as she felt it thrusting again spreading her hind legs further apart. Luna moaned louder than before, keeping her sexy gaze fixated on your face.

“Don’t stop human, we demand you thrust your love into us!” Luna’s dripping flesh gripped tighter around your shaft, and flickers of pleasure surged down your groin right into your body. The horny Princess of the Night bit her lip as her wings flexed far. The room stank of sex and body fluids as her coat became matted with sweat. Luna moaned louder into your face without a care, and she wrapped her hind legs around your waist.

Luna’s horn glowed again, and suddenly the sucking sensation of her hungry pussy engulfing your wet, thick dick doubled in intensity. As you plunged in deep to stop it felt like your cock was still being squeezed further down her narrow, wet passage. Luna heard your desperate moans, and she felt your heavy member throbbing inside her.

“I doubled the pleasure human, is it far too overwhelming?” This tantalizing sensation was incredible, but too much for the body to bear. Luna for sure would end up soaked in hot, thick seed were you to move a slight inch of your dick backwards. Her magical glowing pussy continued to suck and squeeze at your engorged phallus. Having an orgasm now would be mind-blowing, but that look in Luna’s eyes suggested she had other plans. After sharing another slow and lustful kiss, Luna ended her intense spell allowing you to pull out carefully. Streams of pussy juice stained the carpet further as your shiny thickness sprung upwards after passing through her tight, thick lips.

Luna waited as she heard loud panting coming from her partner; eyeing his chest rise and fall.

“We have further demands for you, human!” Luna slowly got on all fours, but she hesitated and blushed. “We hope you won’t find this unsatisfying.” Slowly and nervously Luna presented her hind quarters to you, but this was ridiculous. Luna had the ass of an average porn star; if not even bigger. Her full, plump flanks drew even more attention from anything else about her right now. Surely it wasn’t possible for ponies to be endowed like this, but for Luna it was possible. Her starry tail flowed up from between her moon cheeks as she waited for a reply.

“You are silent human, pray tell us the matter?” Rather than hear a response Luna felt human hands touching her again, no, they were fondling her! To Luna’s surprise she could feel fingers digging into her soft as marshmallow posterior. This sensation was new, but soon it grew to feel arousing. The only thing visible before you now was Luna’s bubble butt, her flanks sank like memory foam under the pressure of your hands. Luna shivered and blushed again as the new touch against her butt started to turn her on. Embarrassment soon gave way to pride, and Luna smiled as she thought to herself.

“And dear sister called me unattractive, yet my subject simply cannot keep his hands off my rear!” Luna grinned and offered more ass to her partner who groped and fondled more and more. It was then that Luna felt your lips softly kissing against her rear. She looked rather surprised trying to understand your intentions. “This human, is he worshipping my rear!? Do they practise this amongst others of their kind!?” Luna could feel her butt being groped again, but a new feeling took over as her cheeks were spread apart.

Luna’s coat was matted with clear fluids between her flanks. Her thick lipped cooter came into view partly exposing her enriched juicy flesh. Luna felt your hardened member jump up between her hind legs, and she turned to look back at you.

“Since you strangely desire to worship our behind, show your Princess adoration for our Royal derriere!” Luna’s demand didn’t fall on deaf ears. She felt her ass being spread again, and then came the sudden touch of your thick helmet spreading her entrance open. Luna felt it slide in with ease, and squeeze between her tight mounds. The horse-like cock buried itself in deeper until Luna felt your waist sinking into her blue butt.

“We desire this position the most, as ponies mate this way! However you are capable of giving us a different experience!” Luna felt hands reaching around her wide Royal Rump. There were loud, wet sounds as your thick meat slid out between Luna’s pursed pussy lips. Strands of clear fluids stuck between Luna’s fat flanks and your waist. Fucking her from this angle felt incredible, and gave you more control. It felt too warm and tempting to pull out all the way. Luna’s body rocked forward and she felt her partner ram into her. The lustful thrusting grew repetitive, and Luna felt her big backside being groped again.

Luna’s moon butt clapped loudly as you held onto her soft dark blue buns; whilst thrusting your hips back and forth madly against her bouncy rear. Luna shuddered again and uttered another horny moan as she felt the wide human penis throb and rub against her sensitive insides. Luna’s pussy juice dribbled from her soaked, thick pony cunt as her partner’s rock hard phallus squeezed in and out of her tight opening rubbing between her folds. Princess Luna moaned again after feeling another tight squeeze from your hands.

“Yes human, show me your love for my rear! Worship my moon!” Loud grunts filled the room as Luna’s cunt was filled with dick. She gasped with joy and rose her moon higher in the air whilst resting on her fore hooves. Luna spread her legs further apart feeling you go wild with doggy style. She moaned much louder between the clapping of your waist against her soft, fat ass. Luna felt your well-hung dick impale her up to her womb as your waist rubbed against her peachy posterior. Fluids had leaked from her hot snatch all over your skin and her coat. Luna caught her breath back and her butt rose up and down.

She smiled again feeling fingers rubbing between her flanks, but then her eyes went wide after feeling something strange. The thick blue ring of Luna’s butthole stuck out far. It felt slightly off putting at first, but after experiencing two holes the third didn’t seem bad.

“Does thou feel comfortable with this?” Luna questioned. Her asshole seemed to spread apart fairly easy, exposing the bright pink flesh inside. Luna felt two fingers prying her open as the lust in your mind started growing again. After dipping your fingers into her soaked snatch, and lubing up her asshole Luna felt warm pressure against her sphincter.

“We are familiar with this, and you seem to be also. Hurry and proceed!” Luna loosened up, and soon enough felt your girth penetrate and spread her butthole open. The thick wet ridge of her anus gripped tight against your sensitive flesh, and her insides felt even hotter. Your teeth remained clenched as you anally penetrated Luna slowly, watching your glistening member disappear into her clean asshole.

After you bottomed out inside her, Luna felt the thick rod move again as your hands groped her wide derriere. Her pussy juice made it easier to thrust, and the warm tightness was numbing. Luna trembled as she felt her orgasm rising to a finish. She’d spend a good few minutes with you, and the best was yet still to come. Celestia could have easily had her way with you. She was aware you were around the castle most of the time, but she wasn’t aware that her horny sister was down here getting off with you.

It had been the best intimate moment between the two of you yet. The last memory being when you two were stargazing side by side. Luna had turned to look at you with her beautiful jewel eyes, and that loving smile that warmed your heart. Of course it hadn’t been the first time her body had been stared at, and because neither sister wore clothes they were always exposed leaving you to wonder what a pony pussy would feel like. Well here you had been filling Luna with your magical thick dick, and the experience was to die for.

Luna’s horn glowed again and a tingling sensation in your sack diverted your eyes. As your balls began to swell under Luna’s magic; they began to swing and smack against her wet pussy lips. They filled to the brim with cum growing slightly bigger as the pressure doubled up inside. The magic field around them seemed to massage and caress them externally and internally. A new magic took over around your cock as Luna’s warm insides began to squeeze and constrict your throbbing member. Another weird feeling passed as your dick started to vibrate slightly. It was almost as numbing as when you first penetrated her.

“We mentioned your cooperation would not go unrewarded! And you were kind not to berate our rear! We aim to stimulate you as much as possible for our climax!” Luna’s tail wrapped behind your waist hugging you up against her big, squishy loveable butt. “You show much appreciation for our behind!” Luna giggled, but was cut off after she felt her clit throbbing. The pleasure intensified as your fingers rubbed and squeezed her sensitive bud teasing her orgasm closer. Damn Luna’s ass was a lot to handle!

“We have enjoyed our lustful session together human, but we must remind you of the purpose of research. Either way we felt the loving connection between us, and -ah- beg of you to -ooh- release your seed inside us!” Luna’s moans pierced the air as she felt her clit being fondled harder. Another hard thrust of your thick dong drove her over the top as it vibrated and pulsed diving deep inside her. Luna felt her clit being rubbed faster until both her holes tensed up, and she howled loudly as her climax exploded through her body delivering jolts of pleasure to her sensitive nerves.

At the same time the vibrations in your dick increased as well as the massaging of your balls until the pleasure blew over, and Luna felt her asshole being filled with thick, warm human seed.

“Yes, fill us with your precious contents!” Luna moaned as she felt spurt after spurt filling her up. It began to drip from her tailhole having already being filled, but more cum was still shooting out. Luna felt you pull out and her huge ass was painted with cum as the everlasting orgasm in your groin continued. The repeated contractions of muscles grew stronger and stronger, forcing your eyes closed and mouth open throughout as the sensation of spunk shooting from your cock continued.

Luna’s peachy rear became covered in your seed as both orgasms died down. Already the Princess of the Night had collapsed as the last drops of thick cum descended on her thighs.

“Come embrace us, human!.” Luna caught her breath looking up to you. She snuggled up with her forelegs around you as you cuddled her back. The kissing resumed and Luna took it slowly with her tongue stopping only to speak.

“That was lovely, we must mate again! For love of course!” Luna nuzzled you before sharing another passionate kiss with you in between her forelegs. It had been an amazing loving experience with her. Still, you decided that back home you’d keep quiet about your sexually intimate experience with this beautifully stunning mare of the night. Luna ended the kiss and cuddled tightly with you, noticing the tiredness in your eyes.

“Sleep well my human lover, you’ll need energy for when I desire you again.” Luna’s peaceful yet seductive words hung in your mind, and your eyelids slowly dropped to a peaceful close, lying snugly against her warm, soft body.

Dat ass!
