Book One: Water

Chapter One

 

TAMAR WALKED INTO her dorm room to see her roommate fucking a statue. True, the statue was laying on its back while on Cybelle’s bed and she was on top of it so it was more like she was masturbating with a stone dildo attached to a statue, but in the end she was the one doing all the work. Cybelle had long beautiful blonde hair that fell almost to her waist, which only served to accentuate the fact that her ass was a little fat. Still, Tamar was enchanted enough by the view to watch Cybelle’s ass go up and down on the long stone cock for a minute before she said anything. It was long enough that she wondered if Cybelle knew right away when she opened the door and just didn’t care, or if the blonde enchantress was so into her masturbation routine, everything else fell away from her senses.

“Should I leave and come back later, or are you going to cum soon?” Tamar asked.

Cybelle tossed her hair to the side and looked over her shoulder at her roommate. She did not stop rocking her hips back and forth still taking pleasure on the very rigid outcropping on which she had pricked herself.

“Soon,” she muttered and doubled the speed of her hips.

For her part, Tamar closed the door and stepped to the side, never taking her eyes off the jiggling flesh of her roommate’s ass. It was beautiful and Tamar felt a familiar burning in her loins. It was too familiar and she tamped down her lust. She knew that what she should have done was left with Brevard’s Book of Elemental Summoning and gotten to her class, but instead she just licked her lips and tried to memorize every bit of Cybelle’s form for later, when she was alone and could masturbate in privacy—and safety.

“Do you mind if I watch?” Tamar asked, still a little uncomfortable about being a voyeur. Cybelle knew that she preferred women, but she didn’t know where Cybelle’s preferences lay.

The blonde enchantress’s smile was intoxicating. “Please.” Tamar wasn’t sure if Cybelle was giving her permission to watch or if she was simply vocalizing her desire to cum. Despite the risks, Tamar slipped her hand down into her leather pants and strummed on her cunt.

Cybelle was getting close. That was obvious. Her breathing, her moans, the motion of her body—and then the statue started to melt away. It wasn’t really melting, Tamar realized after half a second and with two fingers stuffed up her twat, it was transforming back into a human. It took her another second to realize that Cybelle must have transmuted her victim—or partner?—into a statue and taken advantage of him.

“No! No! No!” Cybelle begged out lout, but either she had lost control of the magic or the spell had met its duration. The speed of her hips increased again, but the spell was at its end. The cold, white statue transformed back into a human, a young man of good looks and muscular body. Tamar could see why her roommate had chosen the youth as her toy.

The moment his prick changed from stone to a mere flesh erection Cybelle jumped off his body with a cry of frustration.

“Hey!” he complained, suddenly coming to his senses. “What in the nine hells!?”

“Get out!” Cybelle screamed at him. “Get dressed and get out!”

He lay there a moment, stunned, his hand on his cock, rubbing it, trying to finish what she had started. “Can’t I—?” he started to ask, but Cybelle picked up his clothes from the floor and threw them at him. Tamar noted the clothes were there uniform of the college’s servants.

The servant quickly got dressed while Cybelle stood in the corner glaring at him, her arms folded over her breasts. Apparently she wasn’t worried about him looking at her snatch, but the breasts were off limits. The moment he had fully transformed Tamar had pulled her hand from her pants; she wasn’t sure if the youth even noticed her.

“Fucking prick!” Cybelle cursed when the servant was dressed enough and had left.

“Well, obviously,” giggled Tamar. “What were you doing with him anyway?” She pretended to search her bookshelf for her Brevard’s but was really just stalling to get more information from Cybelle.

“Practicing transformations.”

“Okay, but anyone can transform a floppy dick to hard one. There’s no magic in that.”

“Ha fucking ha. No. I did change him into stone—a beautiful marble statue if you didn’t notice.”

Tamar’s eyes narrowed. “How’d you get him out of his clothes and get his prick hard after changing him into stone?”

Cybelle arched a fine, thin eyebrow. “I transformed him while I was giving him a blowjob,” she shrugged.

Tamar was taken aback. “You know we can use servant volunteers to practice on, but you’re not supposed to do it without permission!”

Cybelle smiled confidently and then started rooting around in her storage locker. When she turned around Tamar couldn’t help but stare at her ass. “I had his permission.”

“Getting it when his cock’s in your mouth doesn’t count!”

Finding what she needed, Cybelle straightened up. Tamar tried not to goggle at her bouncing breasts. She shrugged. “Semantics.” In her hand was an exquisitely carved tool, and it was exactly that, a tool. A large cock shaped from a piece of iron oak.

“You’re also not supposed to be having sex with the servants. You know that!” Tamar wasn’t sure why she was defending the college’s rules, but she felt like she had to say something.

Cybelle threw herself on her bed and spread open her legs. “I know,” she said as she ran the smooth iron oak between her moist lips. “But I don’t care.” She pushed the fake cock all the way into her pussy. “You don’t achieve anything by following the rules.” And then she started masturbating in earnest.

As much as she wanted to stay and watch—and join in—Tamar just grabbed her book and left. She was fairly certain that Cybelle was just teasing, taunting her. Fairly certain. It was far too dangerous for her to have a nice little climax in the middle of the room with all sorts of flammable materials. No, she’d have to wait for later. Besides, she didn’t want to humiliate herself in front of Cybelle only to be rejected.

 

 

Chapter Two

 

THE BEAUTIFUL YOUTH was bent over the hard stone table in the middle of Professor Orlando Cryfix’s private office and laboratory. He wasn’t tied down, but his hands were roughly gripping the edge of the table because Professor Cryfix’s cock was buried in the youth’s ass. He was surprised at the sounds he was making. It wasn’t that it was painful for the youth, if anything he was rather enjoying being buggered by Cryfix’s big cock and that’s what disturbed him.

“Nothing more perfect than a virgin boy’s ass,” the professor grunted as he continued to pound into the youth. The youth was completely naked while Cryfix had only deigned to lift up his robes to free his cock and bugger the young man.

The youth wasn’t humiliated by the treatment; it was the reason he had come to the professor’s office. He wasn’t upset at their disparity in dress; it was what he had expected. “Thank you, Professor.”

“Say it again,” commanded the old man. He might have been more than three times the youth’s age but he was still physically commanding even if he had graying hair and beard he kept trimmed short.

Just as the youth was about to follow the order, Cryfix reached around the boy’s hip and grabbed his hard cock. Despite the situation the youth had found his body responding in a way he hadn’t predicted. Cryfix’s hand felt good and the youth found himself on the verge of climax in a matter of seconds.

“Thank you, Professor!” he cried out as the man’s busy hand brought him off. Thick globs of cum splashed against the table and onto the floor. That wasn’t surprising. The surprising part was when the youth’s body shifted. He became a little older, a little less handsome, a little taller. The changes weren’t drastic, but were strong enough that they were obvious.

Cryfix pulled his cock out of the young man’s ass without finishing. He didn’t need to finish; he had more control than anyone in the college. He came only when and where he wanted.

“You didn’t hold your form, Thomas,” Cryfix said as he rearranged his robes.

Shifty slammed his hand against the stone table. “I know, Professor. I know. You don’t have to tell me.”

“But apparently you need reminding to keep control. Transformation is a wonderful thing, but at this point you are all raw potential and no skill or experience.” One of the greatest advantages of a shapeshifter is the ability to hide anywhere to anyone’s eyes. If you can’t hold your form in times of stress, you’ll never be of use to anyone or even yourself.”

“I know,” Tom repeated. “You don’t have to keep reminding me. But I didn’t come here today to get fucked in the ass.”

“And you’ll never know what to expect when you’re spying on someone or are hidden within an army of enemies. You can’t have a simple little roll in the hay with someone without losing control, you’ll be dead, not just useless, Tom.”

“Okay, Professor. Just don’t call me Tom, okay? Call me Shifty.”

The old man smirked under his whiskers. “I’ll call you that when you deserve it.”

 

 

Chapter Three

 

DOCTOR HERBERT ALPINE liked to teach his Roots, Twigs, and Berries class outdoors because he didn’t like the confines of the college’s stone towers and he enjoyed nature walks as a general rule of thumb. Besides, he reasoned more than once with students and teachers, it is better to learn about something in the real world rather than in the classroom.

His students couldn’t disagree more, and they had year after year. Getting to class was hard enough in the very early mornings when he insisted on holding class, but making them do physical exercise rather than just sitting slack-jawed in the classroom was pure torture, in their opinion. This year’s class was no different from previous years and were a more motley group of fools and wizards to be than ever before, in his opinion.

“We’ll come back later in the week when the moon is full to cut down the mistletoe berries with silver sickles, that is when they are at the height of their powers,” he said as they wandered out of the oak grove and to the break in the woods that was mostly filled by the slow moving stream that was the main supply of water for the college.

“Great, a midnight class,” muttered Shifty under his breath.

“Shush, the old man will hear you,” softly commented Cybelle. In truth, Dr. Alpine wasn’t that old, but he did sport shockingly white hair and was nearly as deaf as a post.

“Now, at the edge of the water we’ll collect several plants today that are useful in several different spells and potions,” Dr. Alpine continued. “You’ll see on the banks a rather attractive—oh my!” He broke off when he saw a pair of naked female legs that were attached to an equally naked pair of buttocks. They were shapely and youthful buttocks and legs, which might have been the cause for Dr. Alpine’s distress.

“Heh, I recognize that ass,” chuckled Damian Anamol. The other students looked at the tall red-skinned half demon.

“Please, Mr. Anamol,” said Dr. Alpine, laying his hand on his chest as if he were having palpitations from seeing naked skin. “Class, turn around and we’ll head back to the towers.” He tried to usher the group away from the stream, but it was an impossible task. Once a class is distracted by the task at hand, it is all but impossible to get them back on track, especially if the distraction is naked female flesh.

“It’s Brooke Drench, the naiad,” Damian said with confidence.

“How would you know?” asked Estelle the centaur.

“I’m more than passingly familiar with that ass,” Damian grinned. “What’s she doing with her head in the water?” he wondered out loud.

“Drinking,” someone commented. The class shuffled around, trying for a better look at the youthful naiad’s naked form.

“Breathing water,” said someone else.

“But why isn’t she moving?” asked Shifty.

His question silenced the class quicker than anything that Dr. Alpine was doing to get them under control.

“Is she dead?” a voice asked quietly.

That question made Dr. Alpine turn around and reconsider his initial thought on the matter.

 

“Drowned!” shouted Dusty as he slammed the door to the dorm room.

“What?” asked Shifty looking up from the oversized tome he was examining with Estelle. Neither was good with basic summoning.

“Drowned!” repeated Dusty as if that explained everything. “It’s how Brooke died. She drowned according to Nurse Alcome. That’s the rumor on campus.”

“Don’t believe every rumor you hear,” said Estelle, tossing back her long hair and repositioning her hindquarters in the small space of the room Shifty and Dusty shared. It was already small enough, but the addition of a third person who was a centaur meant that there was no extra space available.

“How’d you get in here?” asked Dusty of Estelle, quickly measuring her size with the dimensions of the door.

“Very carefully,” she replied tartly and adjusted the vest over her chest. Centaurs as a race tended not to like wearing any clothing; the vest was the one concession to attending a college of magic populated primarily by humans and humanoids. Still, it was small enough to show enough breast and cleavage to easily distract Dusty.

“Isn’t it odd that a naiad drowned?” asked Shifty in spite of himself. He was more interested in studying with Estelle than having a conversation with his roommate. And he was more interested in using studying as a pretense to seduce Estelle than actually studying.

Dusty answered his friend, but didn’t take his eyes off the centaur’s barely hidden tits. “Yes. Very unusual. Professor Cryfix said he was going to lead an investigation as to how a naiad drowned in a small stream of water.”

Estelle rolled her large brown eyes and headed toward the door, carrying the huge tome with her. “Shifty, I came here to study, not wonder about how a naiad died. Dusty, you’re a distraction. I’m going back to my place to study. Are you coming, Tommy?” she eyed he carefully and started easing her large body out the door. It took some maneuvering, but she managed to pass through the portal.

Shifty pointed at his roommate. “She’s right, Dusty. You’re a distraction. I’ll be back later.” Taking a second to make sure that Estelle’s head was already well into the hallway, Shifty winked at Dusty, made a circle with his left index finger and thumb while penetrating the circle with his right finger.

Taking the hint, Dusty nodded and looked enviously as his friend followed Estelle’s shapely rear end.

 

Shifty was at the college to refine his natural shapeshifting skill. Estelle was there to learn the finer points of stargazing and premonition. They were taking the summoning class because the college required of all students to be able to perform a variety of basic magic, including summoning otherworldly creatures. Considering that nearly half the student population was from other dimensions, it seemed a little unnecessary, but it didn’t make that any easier on those not skilled in that particular discipline.

After forcing an imp into reality for a few seconds, giving the black-skinned little monster just enough time to extend a clawed middle finger at Shifty and Estelle before escaping back to its own dimension, the two students decided they had studied enough for the day.

“So, how powerful is your premonition ability?” Shifty asked her. Estelle’s room was on the dorm tower’s ground floor and was closer to a stable than a student’s room, but it was nearly three times the size of his room which pleased Shifty. And she didn’t have a roommate, which was even better for privacy’s purposes. “Do you know what’ I’m thinking?”

She rolled her big, beautiful brown eyes at him. “That’s telepathy, not precog or premonition. And I can tell what you’ll be doing in about five minutes.”

“Oh? What’s that?”

“You’re going to be fucking me.”

Shifty knew an invitation when he heard one. He stepped close to Estelle and kissed her. She eagerly kissed back as he pulled at her vest. The buttons came open quickly and easily, allowing him to cup her very human tits. Not giving any thought to what he was doing, after playing with her tits a bit, Shifty slid one hand down her back, looking to grope her ass, but instead encountered her very equine withers. It caused him to pull back from her kiss.

“What’s the matter?” asked Estelle, already knowing the answer and a bit angry at it.

“Nothing! I’ve just never done this with a centaur before.”

She smirked. “And I’ve never done this with a human boy before. So what? You going to leave?”

“Of course not!” he protested, offended that she’d think he’d give up a chance at pussy. Shifty didn’t discriminate between human and centaur pussy. It was all good to him and he was always willing to try a new experience.

“Then why did you stop kissing me?”

“I wanted to ask if you would like me to go down on you?” he lied. “I’ve never tasted centaur pussy before.”

“Why don’t you find out?” she said. “It seems the least you could do.”

Estelle dropped to her front knees, but kept her back end up in the air, the customary position for pussy eating in the centaur community. Overall centaurs aren’t nearly as tall as their equine counterparts, most topped out at just over six feet, so it was easy for Shifty to directly face Estelle when they kissed and it was easier still for him to kneel down behind her and press his face into a pussy that was familiar and strange at the same time. Normally it was covered by her tail but this she raised up to expose herself and give Shifty access.

A true hedonist, Shifty didn’t hesitate to lick and suck at her pussy. Estelle was immediately pleased with performance and found herself clutching at her tits, pinching her nipples because she didn’t know what to do with her hands. Her hooves clopped against the stone floor and she had to keep at least some of her wits about her so as to not accidentally step on and crush Shifty’s foot or leg.

When she let out a sound that was neither human or horse, Shifty knew he had found her sweet spot. “You like that?” he asked, backing off from her pussy. His face was covered with her wetness and the grin on his face let the world know he was pleased that his lovemaking technique worked well on human women along with centaur women.

“Uh-huh,” she moaned, one hand still gripping a breast while the other steadied her body against the cool stone wall. It was a testament to Shifty’s skills that he was able to make a four-footed person like Estelle, doubt her natural stability.

“Want more?” he asked running his fingers along her wet slit and fingering her bulging clit.

“No. I don’t want your tongue. I want your cock.” The pause in his cunnilingus was long enough that she had managed to gather her wits about her.

That was all the permission that Shifty needed. He stood up and tossed off his tunic and pulled off his leggings. His cock was already hard so there was no difficulty in mounting her—at this thought Shifty giggled to himself. He had mounted horses before but this was the first time he had sexually mounted any member of the equine form—he kept silent on that thought. Centaurs hated to be compared to simple horses.

She was warm, wet, and inviting. Shifty grabbed her back end and started thrusting happily. Everything was doing wonderfully until Estelle looked over her shoulder at him. “Is it in?” she asked, a disappointed look on her face.

While he knew he wasn’t hung like a horse—sadly in this case—never before had a woman of any species complained about Shifty’s size. While Estelle was bigger than the women he had been with in his life, she wasn’t that much bigger, or so he thought.

“I am in you,” he almost barked at her.

“Oh.” The tone of her voice all but crushed him. “I was hoping you’d be bigger.”

“Sorry.” He stopped moving his hips.

“I thought you were a shapechanger,” she said, frowning. “You can make yourself bigger, can’t you?”

“I can,” he said, a bit offended, “but I need a little practice. I just don’t go around making my dick huge. You’d be surprised at how many women are put off by a giant cock.”

Annoyed once more, she rolled her eyes. “Well you’d better figure out a way to get me off!” she demanded.

A flash of inspiration hit Shifty. “Okay, this won’t be my best work, but I’m sure it will do.”

He could imitate fairly easily, the appearance of anyone whom he had touched. That was just natural for a shapeshifter. This wasn’t going to be an exact duplicate, but it was close enough. The only real modification was a gender swap and Shifty had the advantage of actually touching Estelle while doing it with both his hands and his cock. He liked that idea.

“What are you doing?” she asked.

“Hold on a moment,” he replied, closing his eyes and concentrating. The actual change took just seconds, his flesh flowing like a river, muscles and bones altering to suit new function, but when it was over, something wasn’t quite right but Shifty couldn’t say what it was.

The gender swap had gone perfectly. He could feel his much bigger cock buried deeply in her pussy. She hadn’t tightened up; he had grown. Everything else seemed correct. He had never tried a centaur shape before, but he definitely had four legs ending in plain hooves. His pale skin was now covered in fine brown hair that matched what he usually had on his head. Something was off, though…

Estelle had turned away during the change, probably because of the electric thrill it caused whenever he changed while touching someone. One village moonshadow woman he had been fucking loved it when he shifted while buried balls deep in her cunt. She said the electricity made her cum each time. When Estelle turned back she gasped in surprise. It wasn’t from the sexual thrill.

“A fucking horse!” she exclaimed. “You turned into a fucking horse?”

Shifty opened his mouth to explain, but the sound that came out wasn’t common speak, it was a neigh. Internally he cursed. He immediately figured that since he had only been touching her back side, her horse end, he had only picked up on that aspect of her body.

Estelle was offended. Too many humanoids figured centaurs were just the result of a man fucking a horse. That was straight up racist. Centaurs were their own race and horses were just animals. Still, she was open-minded and knew it was Shifty who was fucking her, and she was pleased by the large cock that was deeply buried in her pussy. “You fucked it up,” she said. “But since we’re already halfway there, you might as well finish me off.”

Shifty eagerly nodded his head and started thrusting with his lower hips. He couldn’t speak because horses didn’t truly have voice boxes. Still, he was going to get off one way or another and he was determined to make Estelle cum as well. She grunted and groaned in all the right ways as he plowed her so he knew he was doing something right. He was glad she didn’t ask him to change back. He could have reverted to his customary human shape, but would have been too exhausted to really have sex or change to something else.

They rutted like animals and they both loved it.

When Shifty came, it felt like he was emptying a gallon of cum into his centaur partner. Estelle was pleased at the way his hot cum jetted into her. Getting fucked by a horse was just fine with her, but she didn’t want it to become public knowledge.

After he came, Shifty was proud of himself for being able to maintain the shape of a horse, but then, coming down from the endorphin rush of orgasm, he lost strength and his body slipped back to its natural state.

A wide grin plastered on her face, Estelle turned around and gave Shifty a tremendous kiss. She broke the kiss by slapping his across the face. “I never want to hear anyone call me a horse fucker or you’ll never get my pussy again, understand.”

“Perfectly,” said a slightly stunned Shifty. “When can I get your pussy again?” He always pushed his luck.

“I’ll check the stars tonight and let you know.”

 

 

Chapter Four

 

“HOW CAN A fucking naiad drown?” asked Tamar. “Aren’t they made of water?”

The group was sitting in the circular common room of the dorm tower in their customary study group. While each student at the college was focusing on a particular discipline of the magic arts, they all had to take History of Magic and they all hated it. Professor Crock taught it and, as was common knowledge in the college, he didn’t need to learn most of the history he taught; he was so old he had lived through most of it.

“Actually, naiads are magical elemental spirit beings that can shift between a humanoid form and one of their element. In the case of Brooke, water. They aren’t really made of water. Common misconception,” lectured Shifty.

The entire group glared at him.

“Thank you Professor Doctor Thomas Varieg,” said Cybelle sarcastically.

“I’m a shape shifter,” he protested. “It’s incumbent upon me to know all about those who can alter their own forms.”

Dusty chimed in with new information. He worked in administration offices of the college and often had inside knowledge. “Word has it that she drowned in the stream because she couldn’t shift back to her liquid form,” he said. “As a humanoid, she drowned.”

Shifty still shook his head. “Makes no sense. Even in humanoid form, naiads can breathe water. By definition, they can’t drown.”

“Maybe she was strangled to death,” suggested Tamar with a shudder. As a fire wizard she had a natural fear of any body of liquid larger than a bowl of soup. “The scary part is someone was murdered on the campus.”

“The office is saying drowned, not strangled,” repeated Dusty. “And you saw the body along with us. There weren’t bruises around her neck or anything like that.”

“What if something took away her magical nature,” rumbled Damian. All eyes went to the red-skinned half-demon. It was rumored on campus he had a demoness for a mother and a human for a father who raised him, though how that came about was anyone’s guess and he wasn’t speaking about it.

“How would that happen?” asked Cybelle.

Damian rubbed one of the short horns that sprouted from his forehead. “Well, I know there are ways of stealing souls,” he said.

“You should know,” buttered Tamar under her breath.

He ignored her. “And there are ways of stealing the magic from a person.”

“But from a naiad?” said Shifty. “Come on! Whoever did it would have to rob her of her entire magical essence. I’m not saying that’s not possible, but this is a naiad you’re talking about. An elemental being.”

“A half elemental being,” corrected Damian.

“Still, that only something an incredibly powerful wizard could do. And even then, it’s not easily hidden. That’s world-altering level magic.”

Dusty shrugged again. “That’s all I know. And it’s not like we’re going to find out anything else. The administration here never says anything about any problems with magic getting out of control, or magic being used by someone not authorized.”

An unsettling silence covered the group. To break the hush Cybelle asked, “So when did you and Damian break up, Tamar?”

Immediately her roommate snapped at the enchantress. “We didn’t break up! We were never a couple!”

The rest of the group chortled but they were polite enough to pretend to cover up their laughter.

“One date,” was all Damian said to them.

“That’s not what I heard,” said Shifty. “And I heard plenty through the wall.”

More laughter. It was impossible to tell if Damian was blushing since he was already red, but Tamar’s face was as red as dragon fire and it wasn’t embarrassment, it was anger. “Is nothing around here private?” Tamar raged. “One fuck and you’d have us married! One fight and you’d have us mortal enemies. Enough!” She jumped to her feet and stomped to the door. The desire to make a dramatic exit overtook her common sense. Stopping at the door she thrust he hand down toward the floor and a gigantic envelope of flame surrounded her.

It had been her plan to disappear in the flame, but halfway through the spell, she faltered. As a fire wizard, she could have entered the flames she created and exited another set of flames—the ones in the fireplace of her room was her original choice. Or she could have used the flames as a distraction to slip away in the smoke, light, noise, and confusion. But Tamar couldn’t decide which she wanted even as she was forming the spell and in essence, went nowhere.

Open flames are a decidedly dangerous thing which is why fire wizards are carefully trained—and always trained inside stone buildings. The dorm was stone so it suffered no damage, but her clothes were not so lucky. In the few seconds it took the flames to die out, Tamar sensed that the room had cooled considerably. “Shit,” she said.

“Wow,” commented Dusty. It was an understatement.

Tamar could feel everyone’s eyes on her and it took all of her self-control not to cover herself with her hands and run s
