Aeriella was a young female elf. Her hair was light blond and long, reaching beyond her shoulder blades; she often tied some of it into fancy braids. As elves go she was tall, 180 centimetres to be exact, but unlike other females of her species she was really curvaceous. Her hips were round and full and her breasts big and firm, she was proud not only of her large D-cups, but also how stiffly they stood, not sagging at all. Her waist was incredibly slim, giving her an amazing hourglass figure, and her legs were as long as they could be, slender but strong. She kept her body toned, regularly exercising; she was fit, strong and flexible. She could easily do the splits and stay in that position for a long time. But there was nothing physical to her job, Aeriella worked as an apprentice to a sorceress - a dark elf named Laerinia.
The elf had an exquisitely beautiful face, it combined the delicateness common to her race with a bit of unique sharpness to her features, one might say there was even something mildly predatory in her look. Aeriella's eyes were large, round and purely blue, her cheekbones were high and well emphasised, but they did not dominate the face, her nose was slender and proportionate, her lips full and round, larger than usual for an elf. What was usually hidden from the sight was Aeriella's uncommonly long tongue, she could easily touch her own chin or nose; that feature was useful in lovemaking.
The blonde was not as powerful at wielding magic as her mistress, but she was capable and often worked for her own purposes. This was one of those times.
Aeriella planned to summon a demon. Not just any demon, this one's name was Oanaelur, he served the god of lust Slaanesh and his seed was an extraordinarily powerful ingredient. That seed was what Aeriella wanted to acquire.
She prepared everything - the circle of protection, the spell of summoning and... herself. To get the seed from Oanaelur she would have to have sex with him. While it was not that uncommon for sorceresses to sate their lust by copulating with demons, some level of preparation was necessary. Demons were well endowed, vicious and well known for their amazing stamina.
Aeriella used a magical lubricant, one that could last for a whole day, to make sure she would not get any abrasions. She also cast a spell on herself to allow her sexual organs to stretch, so she could accommodate the demon's huge cock. The elf also used a special pheromone that would make her exceptionally attractive to the demon; the pheromone had a side effect which made the user sexually aroused. But that was fine, no-one said a sorceress could not get pleasure from her work.
The apprentice prepared not only the magical side. She was going to spend a lot of time lying on her back being ravaged by a demon, so she made sure she had a comfortable position. It also had to make her easily available for Oanaelur. Elf set it up the way that would make it easy to collect all of the demon's seed afterwards.
When all was prepared, Aeriella stripped naked in her chamber and began chanting the spell. Shortly a misty shape began to form; it was huge, easily over two metres tall and incredibly muscular. The demon quickly materialised in a solid form. When Aeriella finished her enchantment Oanaelur was standing in all his glory before her. Just like the elf he was naked. Its dark brown skin glistened in the chamber's dim light. He had a roughly chiselled face with a grim expression, but when he inhaled lust began to appear in his look. Sorceress wanted to maintain eye contact, but could not help not to shoot a quick glance at the demon's crotch. His penis was still soft, but even now the elf could tell it was massive; and his testicles were even bigger, disproportionately big. Oanaelur had the size of an exceptionally big man, but his testicles were at least five times as big.
When Aeriella looked back into the demon's face, it was pure lust. She quickly moved to her elevated bed, lied down and spread her long legs. That was all the invitation Oanaelur needed, in two swift strides he was at her bed, but to the elf's surprise he knelt down before her and put his head between her legs. She could hear his loud inhale as once more the demon basked in her enchanted scent. Oanaelur made a low growl, then stuck out his tongue. His head was not too low yet, so Aeriella could see it and she was amazed by it; the tongue was long and snake-like. The demon seemed to be more agile with it, than a fiddler with his fingers. The elf was getting hot at the mere thought of what Oanaelur could do with it. She did not realise that such a hastily reaction of her body might have been the result of pheromones overdose.
The demon did not let her wonder for too long, right after he inhaled her scents, it stuck out its tongue and began licking the elfs tender parts. Aeriella issued a loud moan, the demon's tongue felt better than any other cunnilingus she had experienced. But Oanaelur was not sensitive and gentle, quite the opposite, he was rough and soon added fingers to play; the elf was soaking wet in no-time. She was moaning and gasping, and before she knew it she reached an orgasm. Aeriella made a loud scream, arched her back and clenched her vaginal muscles while the demon's fingers and tongue were still inside of her. Oanaelur kept the play until the elf's cries softened, then he drew out his fingers and stood up. Now Aeriella could see his penis in its full glory, it stood erect and must have been easily over thirty centimetres long, it was as thick as the elf's tiny fists. Aeriella had been fisted before and used her stretching spell, but still was a little afraid.
Oanaelur did not let her fear long, almost immediately he shoved the head of his penis inside the elf. After he enjoyed her tightness for a short while, he pushed the rest of his enormous penis in. Aeriella made a very loud moan, but the demon did not give her time to catch her breath, he instead started to pound her hard and fast right away. With each thrust he withdrew almost his entire huge penis, leaving only the head and then shoved it back violently. The whole time he firmly held the elf by her hips. Grunts and cries escaped the elf's mouth the whole time. It was not lovemaking, it was not even sex, she was being FUCKED. It was rough, violent and moderately painful, but at the same time it was insanely pleasurable. Right now she did not care how sore she was going to feel later.
In, out, in, out. Demons scrotum hitting the elf each time. He was stretching her soooo gooood. In, out, in, out. Like a machine. Warm, pulsating, vicious machine.
Aeriella did not know how much time have passed, while Oanaelur fucked her tirelessly, it was something between a moment and an eternity. In reality it was slightly over half an hour before she had another orgasm. She cried with her whole lungs and clenched her vaginal muscles once more, this orgasm was even stronger and lasted longer than the previous. Her insides tried to squeeze the monstrous and tremendously hard penis with all their might. But despite that the demon kept going with the same fury. Elfs orgasm ended, but Oanaelur was not done yet, he let out a loud roar and fucked her even more furiously. Aeriella felt like he was going to tear her apart despite her protective magic. But she endured, both pain and pleasure were still there.
