Author's Notes:

Clop ahead

Selene watched as they moved through Canterlot. Her eyes bouncing back and forth as ponies were bowing towards them before whispering. Taking a deep breath she watched as the moved towards the gardens. Leaning over she tapped her aunt on the shoulder.

“Can I walk from here?” her voice broke the silence as Celestia stopped for a bit lifting Selene from her back. She was careful where she was placed. Selene stretched herself out feeling some bones in her sides pop as she smiled towards them.

“So follow us” Luna smiled as she walked ahead of her. Selene nodded as she walked behind them her eyes glancing around the garden noticing flowers were moved and items were changed since she was last here. Her eyes caught the sight of a white unicorn with a blond mane smiling as he walked up towards them.

“Auntie” he smiled and his voice caused Selene to stand still in her spot. Her hooves were shaking as she quickly placed herself under Luna curling herself up into a tight-knit ball. Her fins wrapped around herself as she left an opening for her eye to watch Blueblood.

“Blueblood I thought you were staying with Cadence for the week?” Celestia placed her smile on as she looked towards the white unicorn.

“I heard from some friends you were looking for help. Thought I would come back and help” he kept his smile on his face as Celestia nodded.

“Well, we are finished now. Fancy Pants stepped up for the rest of the plans”

“Oh and who is this” he spoke up causing Selene flared her fins up and hissed towards him. Celestia and Luna looked towards her. She had uncurled herself as she glared towards him. Selene kept her eyes on him as she kept her fins flared up,

“This is the queen of the sea Selene,” Celestia spoke up. Luna watched his expressions as he faked being shocked.

“Oh nice to meet you.” he bowed.

“She is also our niece as her mother is our sister who we thought was dead” Luna spoke up watching his expression was pure shock and terror. Selene was watching him as she noticed a pool of water behind him. she waved her fin up causing the water behind him pool up into a sphere before dropping it on him.

“Selene that wasn’t nice” Celestia looked towards the merpony, Her eyes caught the sight of tears in her eyes while her fins and legs were shaking. She moved under Luna as she kept her fins out and glaring towards him.

“I am sorry Blueblood.” Celestia looked towards him as he bowed.

“Of course. I will be in the kitchen as the chef agreed to help me with something for mother’s birthday” he smiled before walking off leaving the alicorns glaring towards Selene. She was gripping Luna’s hoof shaking.

“Selene what has gotten into you” Celestia walked closer causing her to bury her head into her chest as she started to cry.

“Please don’t let me stay here not with him around” she looked up towards her aunt. Celestia placed her wing under her chin as she leaned down.

“Selene, was Blueblood the one from your dream?”

“He is the one….he the one that” she hid her face into her chest as Celestia looked up towards Luna.

“I will make sure he stays in the kitchen” she smiled as she turned around leaving Celestia alone with Selene. She picked up the merpony in her magic before teleporting out of the gardens. Selene moved her hooves from her eyes as she noticed she was in a large open room. Her aunt placed her on a large open water bed filled with pillows and blankets. Moving a bit she could feel the bed shift as she moved around allowing herself to see the room. The ceiling was vaulted with crystals growing from them as a coral lamp hung in the middle of the room lighting up the room causing the crystals to pick up the light. As her eyes moved around the room she noticed she could fit four to six killer whales inside the room which made her jaw drop a bit. One wall caught her eye as it was made from clear glass allowing the sunlight and moonlight to enter the room. Turning around she saw a large tank taking up the whole wall. Glancing in she saw a cave for her to hide in with some coral and kelp and seaweed covering along the wall. Moving her eyes down she noticed small warm rivers running in front of the window while chairs and couches were arranged under the bookshelves that were carved into the wall.

“Wow” Selene looked towards aunt noticing the smile on her face.

“Krill said you would need a large room as your body will grow in time. I also wanted a room for you to feel at ease while you stay here in Canterlot. However, with what you said about Blueblood, I might allow you to stay in Ponyvile but only after a place is built for you” Celestia looked towards Selene as her mane was still sparking. Selene nodded as she curled up in the bed.

“Can I just stay here?”

“You don’t want to go with Twilight?”

“No, I do! But right now I just want to hide” she tried to bury herself into the pillows.

“I will tell Twilight you are here and that is it.” She smiled as she left the room leaving Selene to settle in a bit. Selene was resting her chin on a pillow as she watched the clouds being pushed around by Pegasus in blue and yellow suits. She let out a puff of air as her ears twitched hearing the sound of creaking. Looking up she noticed the silver doors open up as a purple unicorn walked in. Keeping still Selene waited for the pony to walk in closer before raising her head.

“Twilight?” Selene spoke up as the unicorn smiled before nodding her head.

“Princess Celestia told me she teleported you in here. She also told me what happen with a certain unicorn” she walked closer towards the bed before climbing in next to her. Her eyes glanced over Selene’s body noticing the changes easily.

“Wow, Celestia said you grew” she whistled as Selene nodded. As she sat up she noticed a cut along Twilight’s lip causing her to place her hoof under her chin.

“Twilight what happened to your lip?”

“I got into a fight with Discord. Gave him a black eye he gave me a busted lip” Twilight glanced to the side as Selene sighed. She flared her fins out as she leaned in and kissed her deeply causing the purple unicorn to turn a darker shade. She closed her eyes and leaned into the kiss as she felt Selene’s tongue ran along hers before moving towards her lip. She slowly broke the kiss causing Twilight to look up at her.

“Can we go to the arena?” the question caused Selene to jump a bit as it was out of the blue.

“Why?” Selene looked towards Twilight as she looked away blushing. Selene watched her turn a dark red. Selene moved some of the pillows around her allowing her to rest up against them.

“I want to talk to you and Star” Twilight huffed as Selene nodded a bit.

“Okay. I am not sure about this Twilight. I was told not to use my magic” Selene looked towards her as Twilight moved closer to her.

“But you will be drawing from my magic”

“Twilight no” Star’s voice came out as Selene’s eyes had shifted to a pale pink “If I…no we were to draw on your magic will suffer. You will be physically and magically drained. You will end up in the hospital if I did that to you. Now since we are alone what do you wish to talk about?” Star used her hoof and waved her hoof closing the door to the room.

“What makes a mate for a merpony?” That question made Star jump a bit as she glanced towards Twilight noticing her chest was breathing heavily.

“What or who said something to you?” both Star’s and Selene’s voices came out at the same time making Twilight glances up noticing her eyes were two different colors.

“Every pony has been calling me your mate. I’ve seen ponies with the ones they call mates and they are all different than me. They way they look. They way they speak. I… I’m not sure” Twilight was cut off as Selene waved her hoof towards her.

“Okay, one we need Kibby. She is a lot older than me and knows every secret that my grandmother could think of” Selene smiled as Twilight shifted her hooves.

“But what about”

“Me?” Star laughed as Selene rolled her eye “I will keep quiet and let Selene talk. I will be listening” She watched as Twilight nodded as she pulled herself from the bed. Selene leaned against the pillow breathing slowly. She could feel Star glancing around mumbling something under her breath. Her ears twitched as the door creaked open. Glancing over Selene noticed Twilight shutting the door behind her as Kibby was bowing towards her. Selene bowed her head as she sat up watching Twilight move from the door back to the bed.

“Princess told me you wanted to speak to me?” Kibby walked over and sat in front of the door.

“Well Twilight was asking why others were calling her my mate. Though she has noticed the ones who call ponies their mates are different than her and me” Selene smiled as Kibby nodded.

“Oh… I thought Krill told you about mates and merponies princess” Kibby’s eye was twitching as Twilight shook her head. “Well, normally when merponies want to start dating each other they exchange scales. It shows commitment and it allows others to know who they are belonging to. Now since merponies live longer they wait longer to move to the second stage of commitment. From what Krill and Edan as told me the second form and third form has been tossed to the wind as many just exchange scales and that is it. They are mates for life. However back in the day, the second form was where they would exchange part of their souls and magic. This allowed the mates to find their loved ones when they are hurt or sick. We can tell when the other is in danger and if they are angry or mad. Doing this showed true commitment. The third form was vowing like the surface ponies do. Now the reason many ponies here that we call mates are different than you and Selene is because of the second form.” Kibby sighed as she settled in “Now when you do the second form with a surface pony they will gain the ability of a longer life. You Twilight will have a longer life span than normal ponies. I came to the surface when I was almost three hundred. I fell in love with my husband and we created a family. Now he knows all about merponies and has meet queen Roseate in person. When our first daughter left and his family died he was scared about me losing him. We performed the second form and he has been with me since. He has regretted his choice when our kids die but he has his grandkids and great grandkids and so on to lean on. Plus he has me as well. many surface ponies just want to keep with the first form and exchange scales. That’s why we were saying mate since its common around here” Kibby smiled. Twilight nodded as she looked towards Selene.

“Selene what if we?”

“No” both Star and Selene spoke up causing Twilight to twitch. Kibby looked towards Selene in shock noticing the two-tone eyes.

“I will not give you a piece of my soul Twilight. Not with Star attached to me” Selene glanced towards her.

“Why not? Isn’t Star attached to your neck?”

“True the anchor is on her neck Twilight. But my soul is part of her”

“The Black moon curse” Kibby spoke out causing them to turn towards her. Selene noticed Kibby was moving away from her neck causing her to place a hoof up hiding the moon on her neck.

“How did you”

“Your grandmother used this curse as an introduction to curses and how to cure or cast them. The Black Moon curse was created before the celestial sisters, It was used during the time of the alicorns and it moved to the sea forgotten all by the surface ponies. It’s a hard curse to cast and one of the only cureless curse that I know. How far along are you?” Kibby leaned into Selene as she moved her hoof. “Oh…dear your that far along?” Kibby looked at Selene as she tilted her head.

“What do you mean Kibby?”

“You're far along in the curse you hear the curse!”

“Yeah Star! I have been hearing her about what…five or nine years now.” Kibby crossed her hooves as she looked towards Selene.

“Wait what if we do the second form? Would if expand her life?” Twilight glanced towards Selene turning the conversation back.

“Maybe…It will give Selene a longer life span. However, you must wait till she gives birth. Now that brings another thing. Selene are you sure about having a child? You might lose another life just giving birth to them. Your down to four” Kibby watched as the blue eye glanced towards the floor as the pink one started to turn black.

“Star please” Twilight placed her hoof on Selene’s shoulder.

“She will not lose another year for this child” Star growled as Kibby looked towards her.

“I’ve never seen the curse act nice towards the subject before” Kibby leaned in “And I have seen this curse at work”

“What!” they all turned and stared at Kibby.

“Yes, one of the very first cases Roseate had me look into had The Black Moon curse. Oh, it was a terrible case. You would have the pony and then the curse. Oh, the pony would be aware of the curse and would be sweet but the curse would be mad and angry towards the host breaking them and wearing them down till they kill themselves.” Kibby watched as the blue eye closed as Star glared towards the healer.

“I made her tell the others when she tried killing herself. Just because nobles are pissed at what I do doesn’t mean they can take it out on her!” Star slammed her hooves on the bed as Twilight pulled her into a hug.

“Star go find my aunt. I think you would enjoy what you might see” Selene spoke up as the black eye looked in.

“Oh?”

“Please”

“Fine, I will be back later” Star huffed before pulling away causing Selene to placed her hoof towards her head. Opening her eyes she allowed Kibby and Twilight to see her eyes were normal again.

“Twilight by the time I have this kid or children. If you still want to go through with the second form then we will” Selene was rubbing her head as Twilight moved closer towards her nuzzling her neck.

“Queen if you have this curse I think you need to stay here.”

“Kibby I am fine. I have been living with Star since I was young. She hasn’t done anything against me at the moment”

“At the moment Selene”

“Kibby she gave Twilight a challenge to break her. Why would a curse do that?” Selene placed herself against the pillow as she sighed “This is why I do not like my mane up”

“I only noticed when your voice was acting different” Kibby huffed as she shook her head “I will keep this quiet Queen but you need to stay here. Oh, princess if you do go with the second form with the queen knows this. When she dies of this curse you will be in the most unbearable pain. It would be like Celestia throwing you to the sun” Kibby turned around and walked out of the room leaving the two to sit in quiet. Selene looked towards Twilight who was holding onto her hoof at the point.

“Are you okay?”

“Just a lot to think about”

“Should I follow her advice and stay here then?” Selene pulled Twilight close as she rested her head against hers.

“I had so much planned for us. I wanted to take you to Nightmare Night and then hearths warming eve!” Twilight huffed as Selene glanced towards her.

“How about this. Since we are both here, for now, why don’t I meet your parents? You meet mine and your brother can come” Selene was trying her best to change the topic. She noticed Twilight glancing up at her nodding.

“Oh, I bet they would love that!” She clapped her hooves as Selene smiled softly.

“Good” Selene leaned in towards Twilight kissing her forehead “Now should we go outside where others are waiting for us. Or should we spend some much needed time alone?” her eyes glanced down towards Twilight with a smirk on her muzzle. She noticed the purple unicorn started to turn red as her magic flared up. Selene felt the necklaces sliding from her neck before dropping to the ground as Twilight glanced up. She may have been silent but Selene knew what her answer truly was. Placing her hoof under her chin Selene made Twilight look up before planting a kiss against her muzzle while laying her down against the pillows. Once she had her laying against the bed Selene pushed her tongue into Twilight’s mouth causing her to press deeply into the kiss. As the kiss continued on Selene ran her hoof along her sides stopping on her flank rubbing her cutie mark softly. After a while, she broke the kiss allowing the unicorn under her to breath. While she was catching her breath Selene moved towards her neck kissing it lightly before biting it causing her to let out a gasp. Smiling she released Twilights neck licking the bite mark before kissing it.

“Did…you…half to bite me” Twilight looked up towards Selene. She noticed the blush forming on her cheeks as she looked away from her.

“I don’t know” she was turning red as Twilight rolled her eyes giggling. She pulled Selene down kissing her softly.

“Warn me next time” Twilight had a smile on her face as Selene nodded. Leaning her head down Selene kissed her collar bone before leaving a trail of kisses down her body till she came to her breast. Her eyes glanced up as she noticed Twilight turning red as she gave one of her teats a lick before placing it in her mouth.

“Just…no …bite” she let out a moan as Selene nodded while moving her hoof towards her slit. As she was sucking on Twilight’s teat she used her hoof teasing her as she slowly rubbed her pussy and her clit. She could feel Twilight squirm under her as her hind legs bucked.

“Seleeeeene” she wined out causing the merpony to release her breast. Moving her head down Selene replaced her hoof with her muzzle as she used her tongue. She pressed her hoof against Twilight’s entrance as her tongue focused on her clit. Slowly moving her tongue around her clit she placed her muzzle over it causing Twilight to groan. Twilight could feel something slowly building as she felt Selene sucking on her clit while her hoof was teasing her entrance. Her breath was moving rapidly as she felt Selene move away from her clit and down towards her entrance. Glancing down her eyes watched as Selene buried her muzzle into her entrance while her hoof pressed against her clit. Twilight let out a loud moan as she could feel her tongue twist and turn inside of her.

“Seleeeene I…can’t” Twilight moaned out as she came causing her to blush as Selene glanced up at her. Twilight hid her face in her hooves as Selene sat up licking her lips.

“You…so….owe…me…dinner” She glanced towards Selene causing her to chuckle as she stuck her tongue out. She moved up and kissed Twilight deeply causing the purple unicorn to pull the ribbon from her mane causing it to fall around her.

“I like your mane down” She smiled as she pushed Selene over and onto her back. She noticed how red Selene was becoming as she climbed on top of her. Twilight wore a grin on her muzzle as she looked down at Selene.

“So…no magic” she giggled as Selene nodded.

“Wanted to do something…well” Selene was stopped as Twilight kissed her deeply. Selene wrapped her hoof around the unicorn as she rubbed her back. Twilight soon broke the kiss as she moved towards her gills. She softly used her tongue and licked apart of the gills causing Selene to moan. She arched her back allowing her fins to spread out as her tail moved a bit. Twilight could feel the fins along her tail as the merpony would run them along her back teasing her. Twilight sat up glaring down at Selene as she leaned in and bit her on the collar bone hoping to ignore her gills. Selene sat up as she looked towards Twilight.

“Too hard?” the unicorn looked up as Selene shook her head.

“You hit bone” She laid back down as Twilight was blushing.

“Sorry” Twilight kissed her softly before Selene nuzzled her,

“If you want to bite. Move down towards my chest and stay away from the gills and neck area for me” Selene smiled as Twilight nodded.

“Alright” Twilight moved towards the bite mark and kissed it softly before making her way towards Selene’s breast. Her eyes glanced along the scales noticing they were larger as the scales were growing over then instead of around. Using her hoof she pressed down to make her breast appear from under her scales. Selene was moving a bit under her as Twilight leaned down and placed one of her breasts into her mouth. Selene let out a loud groan mixed with a moan. As Twilight was busy sucking on her breast her hoof roamed down slightly pressing on her tail finding her slit. Once she found it she heard a small gasp from Selene. breaking away from her breast Twilight moved her head down towards the area her hoof was resting in. keeping her exposed Twilight leaned her head down and slowly licked her folds causing Selene to move her tail a bit. She was letting out low moans as she felt Twilight’s tongue move around stopping at her clit teasing her slowly. She twitched a bit as she tried not to buck Twilight off with her tail. Selene glanced down as she felt the unicorn place her clit in her mouth while her hoof was still teasing her.

“Twi…light” Selene groaned as she shifted her weight a bit. Her eyes glanced down as she noticed Twilight had shifted from her clit burying her muzzle into her entrance. Biting on her lower lip she moved a bit as she felt Twilight’s tongue inside of her twisting and turning. Selene let out a loud groan as she came causing her face to turn red. Twilight sat up licking her lips as she noticed Selene was rolling on her side.

“Selene?” Twilight moved up as the merpony pointed towards her gills.

“Okay…I need to have my neck propped up. When we do that again” she giggled as she looked up towards Twilight. The unicorn smiled as she laid out beside Selene letting a yawn out. Selene moved in towards Twilight as she nuzzled the unicorn before falling asleep. Outside the room, both Skelly and Kibby were sitting beside the door both of them red as an apple. Skelly glanced towards Kibby as she opened her mouth while her fins were spread out wide.

“Should we?”

“They are lucky I know a barrier spell” Kibby groaned.

“Makes me wish I was on the other end of Twilight”

“Skelly!” Kibby hissed.

“What! If she can make Selene yell that loud” the merpony smiled as Kibby shook her head.

“Just let them rest. After a few hours, we can go in and wake them up, get them cleaned up and make sure they are both dressed for the night” Kibby walked away as Skelly leaned against the door smiling as she shook her head.
