Greetings From The Depths

Varien Quill

Loch Tay was always a rather peculiar lake in Scotland, where the thick fog usually spread for kilometers, barely making the waters visible. But it was also the perfect place to gather the herbs and flowers which were growing only here, like some kind of magical aura was helping them flourish.
Alastair, an equine young man kneeled before one of the plants, quite mesmerized about its quality, which had few long and bountiful leaves. He didn't use the knife, not wanting to hurt it. Just grasp it firmly with gloved hands, taking it out of the ground.
"Ah, Myrica Gale. Wonderful." The Scotsman said to himself, knowing more than just a single language. A nearby bloodhound came closer, sniffing the leaves.
"Careful there, Nessie. We don't want to hurt this poor little fellow, don't we?" The horse chuckled, ruffling the dog's wrinkled head, before placing the herb into his leather bag, down with others.
Alastair stood up, stretching his back with a grunt, quite sore from all the walking and kneeling, quite content about his day's work. But through this fog, it was hard to tell what time it was. He prepared himself for departure when something unexpected just happened.
"Hey, handsome. Come closer..."
The voice was soft, sounding like a melody to his ears, like someone was reciting a lullaby. Alastair thought it was just an auditory hallucination, but judging by Nessie's behavior, he heard that too.
"Is someone there?" He said, before hearing splashes of nearby water. He went through the thick mists towards the lake, hearing the humming of a song he didn't know at all. And then, there she was.
An almost naked, equine beauty lay on the shore, waist down still under the surface, flashing her perfectly chiseled bosom, like an artist himself, made out of marble. Her long mane though was wet, resembling seaweed, but somehow it only added to her beauty. Her skin was smooth, shining under the light.
But there was not much light.
"Good afternoon, miss. Why are you swimming under such weather? Aren't you cold?" He asked, before staring at her thick, hard, and dark pink nipples. "Oh, of course, you are."
The equine lady chuckled and her laughter echoed around, which strangely resembled the croaking of a hundred toads. Or maybe it was just another hallucination? But even he knew there was something strange about that woman, unsure if it was sinister, magical, or both.
"Not at all, handsome. My heart grows to look at such a stud like you, making me warm inside. I'll gladly show you  the best... what are you doing?" She stopped, giving the stallion a puzzled look.
The male took out a book from his bag, searching the contents for a passage he had read a long time ago. He had a stern look on his face, completely sure that it seemed familiar.
"Just... checking something."
When he found the page he was looking for, he suddenly felt a firm grasp around his 'family jewels', making him gasp. It wasn't painful by any means, but he felt startled.
"Miss... what are you..."
"You know how it's lonely down here? Almost nobody comes over to give me some company. And you look like you didn't have a woman for a long, long time. Am I right?"
Normally the stallion would scoff at such crazy and suspicious behavior. But her unusual, sweet scent and look in her eyes somehow made him much more oblivious to potential dangers. Even his bloodhound didn't bark a single time, astonished by the strange, beautiful mare.
Alastair put down the book on the ground and placed the hand around hers, while something moved under his garments and mare's grip.
"Go on..." he finally said, before taking off his clothing waist down. Another strange notion that he usually wouldn't do. But it wasn't a normal situation.
"Sit down, stud. My knight in shining armor." She sang softly, slithering slowly like an eel, shaking her breasts slightly for him. The stallion nodded, sitting on the shore and placing his legs under surface, spreading them wide.
The mare slowly licked her lips, clearly astonished by the look of his massive sack, which contained two perfectly shaped, heavy-looking orbs. While the sheath itself was impressive as well, those balls were quite trophies, waiting for her to touch them.
"I knew you're a handsome stud. But this is just remarkable. I'll take care of these, my prince." She intonated, using the same firm grip as before to weigh both of those jewels, then sniffing their scent.
Both stallion and his hound stared at her, hypnotized by both her voice and eyes, not letting out even a quiet peep. Alastair waited, begging silently for more of her talented fingers. And like she was reading his mind, she delivered.
All of her long and thin fingers, yet another potential sign of danger, carefully wrapped around his sack and sheath, rubbing and squeezing the skin packaging, which contained meaty, impressively large contents. Judging by his gasps and murmurs, he enjoyed her attention and peculiar massage.
And eventually, there it was. A plump pillar of flesh, a totem of masculinity, now throbbing before her face. Full of vigor, it stood tall with thick, visible veins. The mare pulled out her long, thin tongue, rather unusual for an equine, wrapping it around the shaft like a snake. Right from the base to the very top, like a vine.
She licked his cock, massaging and softly squashing it with her tasting organ, while her hands kept rubbing his ballsack rather firmly. He felt the pressure on each of his balls, but all the potential pain turned into pure pleasure, by some sort of magical force. Or perhaps it was just him this time.
The mare stood up tall, but still concealing her waist down in the waters, engulfing his shaft with one single motion, making it bulge through her throat, but somehow not making her gag at all. The stallion groaned loudly, not having such a feeling for a long time, suddenly grasping her mane, and forcing the strange woman to pleasure him orally. The mare only smirked, still sucking on his gigantic, equine dick, loving its taste.
After a few long moments of taking that meaty pole down her throat, she pulled out without a need to gasp for air. His cock twitched violently, begging to be back inside her. The mare only giggled.
"Oh my, you needed that, huh? Don't you worry, we just barely started. And your big companion likes it too..." he looked at the dog who panted, unfurling his long and broad tongue, while something thick and red bobbed between his hindlegs. The mare ignored it, for now, already having quite a lot on her plate for now. 
She licked the shaft from base to the very, now wet tip, before looking straight into stallion's eyes.
"Your member is the biggest I ever saw. And your precious orbs? Perfect. My king." She said, continuing to suck the head of his cock. The stallion would comment on a sudden promotion from prince, but he couldn't let out a single word, while his heart pounded hard. Not a surprise, considering where most of the blood just went off.
The mare from the lake felt a salty liquid coming out of his tiny hole, swallowing it with a broad smile on her face. But it was far too little to extinguish her immense thirst, wanting far more than that.
She slowly and unnaturally dislocated her jaw, somehow not noticed by the pleasured stallion, before shoving his shaft inside her maw once more, like a deep sea creature feeding on its prey. But this time she also used her slithering tongue to catch both of his low hanging balls, to gulp them down as well, groaning deeply to herself.
Alastair's body shook from the promise of upcoming climax, while the bloodhound kept watching, getting inpatient while wanting some fun for himself as well. But apparently the mare had something else in mind.
"Oh, yes. Just like that, sweetheart. Don't stop. Uh... careful with the teeth..." he said, sweating visibly on his forehead.
Indeed, the lake creature grazed her razor sharp fangs along the skin, piercing it with almost no effort, making the stallion to squirm under her strength.
"H-hey, watch the teeth, please..." he murmured, considering pulling out his cock for now, but the mare was visibly more stronger than him, despite her rather petite figure. Alastair panicked, trying to escape.
"I SAID STOP GNAWING ON MY COCK!" he yelled, using rest of his strength to push her back, but it was for the naught. Stallion couldn't even move his legs, like were paralyzed. He looked at them, seeing that his lower limbs had color of the sand, fused with the shore. Alastair suddenly lost his voice to immense fear he just felt.
A glint in mare's eye shined for a moment, along with her broadening and toothy grin, before closing her maw around his cock and ballsack. Deep moan turned into gurgle of pleasure inside her throath, while separating his shaft and orbs from his body with a single, clean bite. A torrent of immense joy flew through her veins, tasting the stallion's flesh, tasting the delicious meat. He squirmed, weaking quickly with each passing moment, not even able to scream, before eventually limping on the ground, suddenly regaining control of his now normally colored legs.
But it was too late for him.
The mare stood up tall, with a jaw full of his jewels, while the shaft slowly went down her throat and eventually the stomach. When the balls were swallowed as well, she let out a soft hum, turning into sweet sounding melody like she was trying to put the poor stallion to sleep. 
Alastair grasped the empty spot between his legs, which was mysteriously healed within a blink of an eye. But even if there was no wound, he still was deeply hurt and betrayed, now sobbing quietly on the ground, right before losing consciousness.
The mare stepped onto shore while her glass-like hooves didn't even make a sound while she walked, averting her gaze towards the hound, who didn't know what to do.  His deeply red shaft bobbed violently, almost digging through the ground below him.
"Good boy. I see you're as impressive looking as your master. I'll take care of it..." she sang, rubbing his head softly with her long fingers. Nessie reacted with panic which swiftly turned into submission and love. He licked her hand, clearly enjoying her petting.
The water mare kept massaging his folds, eventually forcing him to collapse on his back, exposing his belly, shaft, and low-hanging ballsack. She rubbed his stomach, wrapping her hand around the twitching, deeply red pole, moving it from the bloated knot to the very tip, grasping it firmly.
The dog panted loudly, occasionally swallowing his saliva, clearly excited from all of this previously unknown pleasure. After all, it was his very first time to be used in such a way. He was so caught in the moment, Nessie completely forgot about his unconscious master.
The mare smiled, lowering her head before kissing the wet tip, before shoving it into her maw just like she did with Alastair. The snake-like tongue danced outside, suddenly tasting each of the musky orbs, taking them into her jaw as well, while the mare listened to a litany of feral moans and whimpers.
She wanted to take her sweet time with this dessert, but as in life, everything had its end. The mare grinned, showing off her collection of differently shaped but similarly sharp teeth, before closing them around his genitals. With a single swift movement, she took all of it, tasting them in her mouth, letting the meaty weights move down her throat, filling the void in her unnatural stomach.
The dog yelped, moving all of his limbs in sudden panic, trying to stand on the wobbly legs. Finally, he managed to return to his paws, quickly running to the only place he knew was safe. His home. Not even the love and obedience to his master could be as strong as his feral instincts.
Mare of the lake let out a soft sigh, before slowly returning to the depths of the water, right after giving one final glimpse at the still unconscious body of her temporary lover. And with that, she was gone.
A long time after, the stallion woke up, sore from the previous fun with the mysterious woman. Was it all a dream? In a panic, he checked the spot between his legs, seeing in horror that it was very real. Now a gelding, he lost his dream of ever becoming a father. Or even a lover.
Completely devastated, he eventually stood up, put on his clothes, and walked back to the village, thinking about his future. Although he forgot his precious book, still opened it and lay down on the ground on the same page as it was left on.
