Luna was beyond nervous. It had been so long since she had spoken to him, let alone seen him. How was he going to react to her? Would he be angry, would he be happy? Luna's mind raced at the possible expressions. Gently rubbing her hand over the book's thick spine, Luna knew there was only one true way to find out. Igniting her horn, Luna focused her magic on the floor. Cautiously, Luna traced a circle of magic along the floor. Slowly, the faint light danced and merged until a strange glyph marked the ground.

"Now, let's begin." Luna gulped, swallowing that bits of courage before licking her lips. Luna then opened her mouth and began her incantation.

"Et pecus antiquus desiderio carnalium invocabo. Revertimini ad me, et benedicam mortale regnum tuum complexum. Et vocavi vos et in tempore necessitatis tangendo petitis reliquis libido. Ut mihi ... Asmodeus*."

As Luna's words left her lips, the book vibrated and began to glow. Soon enough, the book fell to the ground, pages flailing and tearing from their binding. Luna took a few steps back to watch her "friend" slowly materialize. Pages bent and curved, sticking together to form some manner of creature. Words on the pages thickened, darkening the pages into a deep, dark black. Eventually, the summoning reached its completion. Towering before Luna was a massive beast. Easily taller than even the mightiest of minotaur with twice as much muscular. Its large hooves pressed against the ground with a serpent-like tail gently tapping behind its frame. Luna's eyes widened at the creature's head; which was only a unicorn stallion's skull. And what caught Luna's eye the most, was the creature's massive, throbbing cock.

"H-hello...Asmodeus." Luna greeted, giving the beast a small bow. "I am so sorry it has been so long. I hope you are doing-"

"L...un...na..?" Asmodeus asked, staring down at the princess. Reaching out his massive hands, the demon gently rubbed Luna's mane. "Ha...s...been...so...long..."

"Asmo-Ahh?!" Luna's voice trailed off as she felt a tingling grow inside her. This tingling, though once a faint memory, was all too familiar to Luna. It was Asmodeus' touch, and it was a welcoming feeling. "Mmm, it's been so long. I'm so sorry, I've been-"

"Shh." Asmodeus softly hushed the Alicorn, pressing his massive hand on her mouth; silencing her. "Together again."

Luna could almost burst into tears at her reunion. She had long forgotten that Asmodeus could be gentle and caring. She only submitted herself to his advances, letting the creature explore her body with his hands. Asmodeus' hands shifted slowly, moving down Luna's body; every gently motion over her curves sent a shiver up Luna's spine and quivered her deepest core. Luna's eyes sparkled as she stared into Asmodeus' eyeless sockets. Slowly, Luna saw Asmodeus' scarlet tongue dangle from from his skeletal maw. Luna gulped at the sight of the tongue, opening her mouth and leaned toward the tantalizing appendage.

"I've missed you." Luna cooed, moving to kiss Asmodeus' lipless mouth, letting his long, thick tongue enter her mouth.

Luna only let out deep, sultry moans as she felt Asmodeus' tongue wrap and embrace her own. Luna felt as though her strength was being drained from her, but she didn't care. Pressing herself harder against Asmodeus, Luna only wanted to feel his body against her more and more. Luna could feel her soft breasts and stomach press against Asmodeus' body, how warm he felt and his fur was so soft and enticing. Luna could only give in further, ignoring how Asmodeus' hands was shifted to her hips and was now feeling up her soft flank.

"Please." Luna moaned, letting her mouth be free of Asmodeus'. "Don't tease me."

Asmodeus did as requested and pulled away, letting Luna get a few inches away from his body. This did not last long as Asmodeus seemingly vanished into a black mist; only to instantly reappear behind Luna. Luna was always curious why he chose to move this way when he could've easily walked behind her, but at this moment, it didn't matter. Wrapping one large arm around Luna's waist, Asmodeus effortlessly lifted Luna upwards. As Luna was pulled upwards, Asmodeus' other hand moved to her dripping wet snatch, his skilled fingers slowly rubbed at her soft pussy lips.

"As-asmodeus." Luna moaned, tilting her head at an angle to get back to kissing her demonic lover. "Keeping going."

Asmodeus did as Luna moaned, letting his almost magic fingers rub and flick at Luna's pussy. But he did not move his fingers past the wet entrance, only enticing and teasing Luna further. Faint memories of her past times with Asmodeus slowly poured into Luna's mind. The images were almost mirroring this one. It wasn't until her memories fully returned that Luna realized what was happening; Asmodeus was trying to reenact the first time their fucked this time as a way to welcome Luna back. Luna's eyes watered with joyous tears, she was so afraid Asmodeus would hold her banishment against her, but he treated her with the same love and care as their first time.

Sensing Luna's joy and compassion, Asmodeus moved on to his next task. With his great strength, the demon shifted Luna's weight around, realigning her to she was lifted above his head, with her damp pussy lips facing him. Without any word, Asmodeus opened his mouth and slowly slithered his tongue towards Luna's wetness. Luna herself, given how high up she was, had to lean forward and press her hands on Asmodeus' head to keep balance. Asmodeus continued his advances, rubbing the tip of his long tongue at Luna's entrance.

"Wait." Luna finally said, trying to maintain her composure during her pleasure. "Let me get readjusted." Nodding his head, Asmodeus let Luna shift herself and with a slow and graceful motion, she was now leaning forward across the demon's chest. Her glistening pussy still waiting to be tasted, but Luna's head was now facing Asmodeus' fat and meaty cock. "Now I can make you feel good."

Asmodeus seemed to smirk,despite having no lips, and continued her act. But seeing how assertive Luna was being gave the sexual beast all he needed to know it was time to get rougher. griping at Luna's thighs with both claws, Asmodeus clamped his mouth hard on Luna's crotch. The size of his mouth easily enveloped Luna's cunt and a decent portion of her soft flank. Luna let out a moan in pleasure, followed by a wide eyes gasp as she felt her pussy walls being parted by Asmodeus' lustful and miraculous tongue. Luna had long forgotten how big Asmodeus' tongue was, as thick as an above average stallion but nearly three times the length.

"As..modeus! A-ahh!!" Luna moaned loudly, thanking herself for the barriers she set up earlier. But what really brought a red blush was Asmodeus' cock bobbing in front of her face. "So big...and warm..." Luna opened her mouth to let her tongue gently run across the thick cockhead. "Mmm...So tasty..." Luna could feel her senses slowly become a haze as she licked up the creamy precum.

Luna could not long hold on to any sense of composure or dignity, Luna wrapped her lips across the thick cockhead, suckling on it as if it were a giant bottle of sweet nectar. Asmodeus let out a low groan as he felt Luna's tongue slowly slid into his open urethra. The demon only took the pleasure from this, and continued to plunge his own tongue deeper into Luna's pussy; easily pressing at her cervix. Luna's muffled moan only drove Asmodeus to press further, eventually prying open her womb, letting his tongue fill her deepest core. Luna's eyes went wide open as she could feel her stomach stretch from the sheer mass in her damp hole.

"So...full!" Luna moaned, only driving her mouth further over Asmodeus' cock, but it was just too big for her.

Asmodeus was too lust driven and in pleasure to care for Luna's limits. Taking one of his hands from Luna's thigh and pressed it on the back of her head. Luna offered no resistance as she felt Asmodeus push her head over his cock, forcing the thickness in her small but flexible mouth. Luna's body quivered as she orgasmed just from feeling the thick cock meat inside her mouth after so long; her sensitivity only heightening as Asmodeus licked and drank her love juices, swirling her insides in a pleasurable mess. Luna continued to suck and press herself further on Asmodeus' cock, eventually taking it a deep as the back of her throat; pre cum dripping straight to her stomach. Luna could not stop herself, every time she pulled herself away to breath, the scent and taste of that thick, intoxicating musk only drove her to clamp he mouth back around it. Soon enough, Asmodeus felt a sensation bubble within his loins, his heavy balls tightened as they prepared to unleash his first of many loads in Luna's body. Pulling out his tongue with a body shivering roar, Asmodeus fired his load into Luna's mouth.

Luna instinctively tried to escape what could be an ocean of cum, but Asmodeus gripped the back of her head, forcing her to drink it all. Luna's eyes rolled to the back of her head as she obediently gulped down all that she was fed. At first, it simply puffed her cheeks like some adorable rodent, but after ingesting so much cum, Luna felt her stomach widen and fill. Though she couldn't see it, on anything for that matter, Luna could feel her belly bulge and expand. Not wanting to burst from so much, Luna quickly used her magic to enchant her body, making it more flexible and near invulnerable. Nearly pulling his cock away, Asmodeus let in one more good thrust before he emptied himself completely. Though not a moment after his cock was uncorked from Luna's mouth, the Princess coughed up and vomited what excess cum could not stay down. The sight was so enticing, that Asmodeus lost his grip of the Alicorn and dropped her on the large puddle of cum, coating her twitching and gurgling body in its steaming warmth.

"So...much...so...good..." Luna gurgled in pleasure, her body almost rolling around in warm cum. "I'm so stuffed." But Asmodeus was not yet satisfied, his cock was still hard and was bobbing, almost tempting Luna's senses with it's musky presence. "Oh? Still not satisfied?"

Asmodeus gave no answer and instead grabbed at one of Luna's legs and angled her to be fully on her back; with her saliva and juice covered cunt facing the lust demon. Asmodeus' tongue licked his lipless fangs as he stared at Luna's quivering marehood. Grabbing at her other leg, Asmodeus pulled Luna up and slapped his thick cock along her wet slit, showing how large it was against her body. Luna only shivered as goosebumps overtook her. Asmodeus was so big, could such a thing even fit inside her? But if she could take it in the mouth, she could take it in the pussy.

"Don't keep a mare-AHH!" Luna tried to tease Asmodeus further, but he was already plunging himself inside her as she flirted.

Asmodeus' cockhead parted Luna's darker lips as it slowly made its way in. The demon's thick shaft was careful to not break through too soon. Asmodeus wanted to savor this tight and warm wetness before fully fucking his Alicorn partner. This teasing did not slip past Luna, but she was in too much pleasure to care. How Asmodeus was filling her was almost too much, but Luna was still not full. She wanted more! Using what little strength her sensitive body could muster, Luna leaned up and softly wrapped her hands around Asmodeus' thickness, the demon staring into her twinkling. lust hazed eyes.

"It's okay Asmodeus." Luna said softly, rubbing Asmodeus' shaft as she stared at him with begging eyes. "Fill me up with your perfect cock."

If he had lips, Asmodeus would've smirked as he set up to thrust inside her mistress. Leaning forward, Asmodeus put the bulk of his mass over Luna's body; the weight sent a new pleasure over her. The crushing feeling, as if she could never escape this lustful beast was making Luna even wetter, her pussy almost swallowing Asmodeus. The demon saw this as his chance to finally press himself deeper. Leaning forward to breathe heavily against Luna's face, Asmodeus pushed himself even deeper. Luna gasped as she felt her body bend and expand to the demon's will. She was at his complete mercy now, and he was going to fuck her until she was a broken, bubbling mess; an idea that only made Luna blush and become wetter.

After a few moments to let Luna's pussy and midsection become more accustom to the sheer size, Asmodeus then thrust himself inside. Luna opened her mouth in another gasp but Asmodeus' thick tongue slithered and forced its way in, blocking her ability to make audible noise as she felt her body shape to the demon's thickness. Luna could feel every vein, every bump and grove of Asmodeus as he moved in and out; slow at first, but he was picking up speed soon. A thousand years had not diminished Luna's marehood in the slightest, she was just as tight and warm as Asmodeus remembered.

Luna was not sure how to process anything anymore. She could feel how big Asmodeus was, how his massive cock was spreading her lower lips and how full her stomach was becoming by just cock meat. She could feel the tip in her womb press against her stomach, churning and mixing the vast amounts of cum in her belly. Even with the muscular beast atop her, Luna knew she must look so bloated, pregnant even; the idea of this sex demon knocking her up was actually making her wetter and almost more fertile as she accepted being the soft cocksleeve to Asmodeus. Soon enough, she could feel the creature's cock swell with expected passion. It was growing inside her, how his twin orbs were also growing to the size of a filly's head was clear sign Asmodeus was going to cum again.

Luna could not make any noise aside from moans and begging coos as she welcomed this demon's thick and burning hot seed inside her cunt. She wanted it, she needed to feel Asmodeus fill her again after so long. Here it came! Asmodeus was now thrusting even harder than before, Luna's inner folds were taking a beating that only she could handle; no ordinary mare could not succumb and break from this cock's assault. Luna could feel her mind completely giving over to the cock inside her, and the beast it was attached to. She could not live without this now, no stallion, minotaur, or even dragon could make her feel this good. Her pussy was carved, heated, and molded only for Asmodeus, and his burning loins.

As Luna's mind and consciousness shattered under countless orgasms, Asmodeus released his own orgasm inside the mare. His balls fully emptied again and again with each thrust. The cum widening Luna's body, bloating it as if she had nearly eaten an entire classroom of foals. If anypony were to see her, they would not only assume she was about to give birth, but that a whole litter was coming out of her. Asmodeus' cock corked the wet entrance, preventing the cum from escaping. Luna's womb was saturated and basted in demonic spunk. So intense were Luna's orgasms from this fucking, that she started vomiting up the cum that was in her stomach, coating her face and body in the warm, white juices. Asmodeus pulled his tongue away just in time to watch Luna bath in his cum, what she lay in, coughed up, and finally what he fired on her as he pulled out covered her in an ocean of steaming, thick cock gel.

"S...o...g...o...o...d...!" Luna groaned as she lost all ability to speak and fell into a heavy unconsciousness.

"Un...til...ne...xt...ti...me..." Asmodeus bowed slightly, proud of his word. His body then glowed a dim blue as his body started to break apart. Within seconds, Asmodeus had reversed his own summoning, turning back into the words and pages of his book gently laying on the ground. Although Asmodeus still had it in him to keep going several more rounds, he knew Luna was not able to handle it yet. Just before the book fully closed, the last words on the back page read: "There will be other times."
