The Tail of Three Dragons
In the magical land of Arwok, outside the small town of Arrowedge, sat an abandoned castle, buried in the rock, forgotten in time and seemingly abandoned. except for three Dragon cub sisters
"Damn it," a young Dragon cub said, waving her finger, which was injured from cooking. This was Sapphire, a blue dragon, wearing a dark robe. who was preparing stew as she was cutting potatoes and sliced her finger with a knife? Sapphire dropped the knife, which clattered on the floor. holding her finger up light green magic surrounded and closed the wound
"Dinner" Sapphire called out to her two sisters who ran down the stone staircase. The first was Ruby, the oldest sibling, who was red, wearing makeshift armor, a dagger attached to her hip, she was the hot-headed fighter type who collected weapons and armors, often slashing up mannequins in her training room, she was the de facto leader of the triplets. and the youngest was Emerald, who had green skin wearing a fancy dress, she was the most childish and playful, she studied music and sewing, had a beautiful singing voice, and skilled with the lute. Sapphire was the middle child and voice of reason who studied Cooking, Magic, Alchemy, Gardening, and Botany, she made their meals and medicine.
"Looks good," Emerald praised, running her spoon through her bowl, enjoying the stew Sapphire made through the veggies she grew as they enjoyed the dinner.
The three Dragons lived alone, without parents, and setting up home in the old castle. Emerald asked what the sisters thought of her new dress, doing a twirl.
"Don't I look pretty as a princess?" Emerald asked, fantasizing about the role, being swept off her paws by a knight in shining armor, dancing at elegant balls as Rube reminded her that 'Prince Charming' would likely cut her head off. killing the fantasy as she admired her dagger, poking a veggie with it as Emerald pouted
"I think you look beautiful Emmy" Sapphire complimented, telling Ruby to not discuss a topic like that at the table as the red dragon rolled her eyes, eating as she thanked the middle sister for dinner.
After their meal the three went on to their own things. In Ruby's training room she was admiring the collection of weapons she looted, maces, axes, and lots of cool swords. Ruby pulled one off the rack. It was mid length, single hand as she lifted it with ease.
"Die" The dragon yelled charging it a mannequin holding a wooden sword and shield, playing sword fight with the target as she swung the blade down, getting stuck in the mannequin's head.
"Oh, a wise guy" bearing her claws as slashing at the wooden dummy, after knocking it over she pulled the sword out, flustered and breathed heavily. Ruby was usually exhausted from training but she had just started as this feeling was coming from her groin, the dragon felt the crotch of her leather pants, noting how hot it felt. the dragon undid her pants, touching herself she noticed how tender she felt, gasping from feeling her fingers.
The red dragon realized this feeling was new, never having thought about her vagina before now as his cool scaly hand felt so good on it. worried she was coming down with some illness she decided to check with Sapphire, putting her sword back on the rack and leaving her Training room. Ruby made her way to the library, shelf was lined with books of all topics as the Blue dragon sat on a chair, curled up reading a book.
"Hey Saph, I think something is wrong with me," Ruby said, looking to her younger sibling for help admitting she was the smartest as she asked what was troubling Ruby. The red dragon explained her Vagina feeling hot as Sapphire lowered her book.
"Sapphire, Sapphire" Emerald called and entered the room distraught as the blue dragon looked at her younger sister asking what was bothering her.
"I was laying in bed, tummy down as my privates were pressing against the mattress and it felt really good, I started dragging it along the sheets and enjoyed the feeling then I made a mess in my bed," Emerald said a bit embarrassed as she pointed her index fingers together as Sapphire looked through her books on Dragon Health. Sapphire found one that was old as she blew the dust off opening it, reading the text, looking for stuff centered around the vagina.
"Here it is, 'Spring fever' Sapphire responded as the sisters looked at her confused, asking what Spring Fever was as Sapphire kept reading the text.
"During the spring period, female Dragons enter a heat where their instincts seek out a male to partake in sexual activities with" Sapphire read realizing she also had these feeling but they were subtle, she continued reading saying the urge would only get stronger until they successfully find a partner to satisfy them.
"There are no boy dragons around to have sex-e-al activities wite, what are sech-oo-al activities," Emerald asked he most innocent as Sapphire turned the page seeing a male dragon and female partaking in intercourse.
"Gross, gross gross" Ruby said, averting her eyes from the image as she asked if they had to do this. Sapphire nodded saying it would only go away once they have sex, but it would come back later, according to the book, dragons are very sexual creatures.
"So where do we get a boy Dragon?" Emerald asked, not knowing any dragons aside from her sisters, and going out in public was a big no-no, due to them being dragons and their age.
"I don't know about Dragons but I know how to get a man here," Ruby explained, not wanting to do this but acknowledging it had to be done as they turned to face the oldest sister. Ruby explained there was this thing in Arrowedge called a 'questboard' where people would advertise and offer rewards to adventurers for completing quests, admitting snuck out on occasion.
"I suggest we put an ad asking an adventurer to come here and have sex with us, we're dragons we have a huge pile of gold, we can spare some coins" Ruby suggested as Sapphire looked at her.
"That... could work but we have to dress it up, not blatantly ask someone to have sex with three dragon cubs, she placed a sheet of paper on her book and scrawled in pen thinking of a way to word the request.
"How about this: Young Maidens need help from a heroic knight in abandoned Castle" Emerald commented, saying it made her feel like a princess as Ruby sighed, reminding her in those kinds of quests the knight rescues the maidens but kills the dragon.
"How much should we reward, I think 3,000 gold seems fair" Sapphire asked as Emerald nodded. Ruby suggested they add "must be able to handle dragons' on the quest. Sapphire declined, saying it was best they didn't expect dragons.
"This might actually work" Sapphire added looking at the final version of the quest, hoping this slip of paper would draw an adventurer to their castle. then when they got here the girls could partake in the sexual acts. 
After dropping the quest off the three sisters spent the night preparing their castle, cleaning the cobwebs, preparing a meal freshening up with a hot bath, they wanted to look their best for the next few days when someone would enter their house and they would get to experience sexual acts for the first time.

"You really think this will work," Emerald asked, tuning her lute,  plucking the strings, playing a song, looking at the midnight sky. Sapphire was heading the box, learning about the various types of intercourse, making notes to go over with her sisters. Ruby, bored, unable to train with this heat killing her, they needed to get laid fast.

-At Arrowedge, the next day: Sir Daniel, a high-level Wolf adventurer was looking through quests.
"Find a lost spellbook, kill a tribe of goblins, beat up some raiders, what's this. "Young Maidens Need Help, looking for a heroic knight, location in Abandoned castle, reward 3,000 gold," Daniel said taking the sheet, more interested in helping the maidens than the gold. he would stop by the store before his quest, sharpen his sword, stock up on health and stamina potions.
"May I recommend Steel plate armor sir, it is not as heavy as Iron Armor and it's tougher,'' the merchant said as Daniel Nodded, handing the Merchant some gold and equipping the Steel Plate armor.
"Now if you must excuse me, I'm off to help some young Maidens," Daniel said checking his bag, he had his potions, a torch, his sword with a fire buff. some food and drink items. concluding he had everything he needed ready for whatever was in that Castle... or so he thought
