The morning came and Twilight was the first to awaken. What she didn't notice was a small wisp of Equestrian magic sneaking through a gap in the door and into her head. Her eyes flashed a deep purple momentarily as she washed up and brushed her hair. She failed to notice it and went on with tying her hair in a ponytail and getting dressed, leaving Sunset to sleep peacefully.
The others woke one by one and each headed home together. Applejack insisted on helping Twilight with the dishes from the previous evening and once all their work was finished she headed home with Rarity in tow. Twilight glanced at her phone as it read 10:30. Her parents wanted her to be at their house for dinner by 2 PM so she knew Sunset would need to be woken soon.
She walked into their bedroom smiling sweetly. "Sunny, wake up."
After receiving a response of a grunt and a snore before Sunset fell back to sleep she yanked the covers off.
"Sunset! Wake up!"
Sunset startled fell out of bed and bonked her head on a nearby dresser.
"Owww. OK I'm up already!"
Twilight giggled. "Come on silly, you have to get ready, we're going to my parents house in a few hours for dinner remember?"
"I just hit my head, and all you care about is a stupid dinner? Cut me some slack Twi."
Twilight just stood there laughing at Sunset's misfortune for a moment longer before offering her a hand up.
"Oh come on, maybe it was a bit extreme but it was still hilarious Sunset."
"Not to me it wasn't."
Sunset washed up and chose an appropriate outfit. By the time the two of them were fully dressed and ready the time was 12:30 PM so they decided to begin walking to Twilight's parent's house.
Twilight kept thinking back to Sunset hitting her head and almost burst out laughing again. She thought to herself. "Why was that so funny? I shouldn't be laughing at Sunset getting hurt but I can't help it."
A voice within her head spoke softly.
"You laugh because she is weak, and you are strong. The strong mock the weak that's how it's always been."
"Perhaps I am stronger than her, it's not something I really thought about, but I am slightly taller and my magic is far stronger. Maybe when we get home I'll remind her who the alpha of our relationship is."
The reached the house and knocked the door being greeted by Shining Armor.
"Twily! And Sunset. You made it, come on in, it's freezing out there." Shining gave his sister a big hug who reluctantly returned it. Sunset was beginning to get suspicious.
They entered the house to see Twilight's mother cooking in the kitchen with her father and Cadence relaxing in the living room. Cadence notably a little plump around the mid section.
Sunset was the first to notice. "Hey Cadence, you look a bit uhh, chubby there. Something you want to tell us?"
"So you noticed. Yep Shiny and I are having a baby."
"Wow, how far along are you?"
"5 months. It's been a long time since we've seen each other Sunset."
"Well I'm sure you'll be a great mother. Isn't that right Twi?"
Twilight scowled momentarily but put a quick smile on. "Yeah you'll be great Cadence."
"Look at them, so happy together. Why cant I feel like that with Sunset? Every day is as boring as the last, even during the holidays. Someone needs to take charge."
"And that someone is you Twilight." said the voice in her head. "Embrace my magic, and you can do whatever you please to her or anyone else."
Twilight smiled and the next couple of hours were uneventful.
Dinner was plated up and everyone ate their fill with plenty of Ice Cream in the freezer for dessert. After dinner Twilight spoke to her mother. "Hey mom, you mind if we head up to my old room?"
"Don't do anything too frisky you two." She winked back.
"Come on Sunny." Sunset followed Twilight up to her old room a little wary. Twilight closed the door behind them and locked it shut. Before tackling Sunset to the bed and kissing her roughly.
"Woah Twi, take it easy girl. What's got you so riled up?"
"Sunset, you never take charge. You never do anything without consulting me first. If I didn't know any better I'd say you were being rather submissive. If you needed me to take charge of our relationship. All you had to do was ask." Twilight's voice became more sultry with every word.
Magic bound Sunset preventing her from moving. While Twilight kissed her passionately and nibbled on her neck. She released the magic hold allowing Sunset to move again.
"They'll get suspicious if we spend too much time up here, but don't worry Sunny. I've got plenty of plans when we get home." Twilight laughed almost menacingly.
Sunset was scared. This was not her Twilight, and as she gazed deep into Twilight's eyes she saw what she feared most. Her eyes had become a deep purple with traces of black and the smallest hint of a green flame adorning the pupil. Soon Twilight wouldn't be in control. Sunset knew something had to be done.
Sunset excused herself from the family to use the bathroom. But secretly she texted her friends to meet them at the park in an hour. Upon returning she spoke to Twilight's parents.
"Thank you for the wonderful meal, I'd love to stay longer but I'm a little tired, and I'm sure Twilight wants to get home don't you honey?"
"Oh yes Sunset let's head home."
Midnight Sparkle couldn't believe her luck. All she had to do was wait till they got home, take over again and steal the geode magic. With the magic of 2 Geodes she could easily overpower the rest of the group and claim their power too. "Twilight is such a sweet little angel, it's a shame I need her body as my vessel."
"Hey Twilight." Sunset said as they walked. "Do you wanna take a walk in the park first? I think it'd be nice."
"Sure Sunny, whatever you want." Midnight said keeping up the facade that Twilight was in control.
Once they got there however, the girls were waiting.
"Oh hey girls." Midnight said. "Why are you all here?"
Sunset then pushed her aside and ran to the group.
"Cut the crap Midnight, we know you've taken Twilight and we want her back!" Sunset growled angrily.
"Well I was hoping to keep this going a little longer, but I suppose needs must."
Twilight's body rose into the air transforming into the familiar form of Midnight Sparkle.
"I should really be thanking you Sunset, that trip to Equestria revitalized the magic and allowed me to take form again. I'll give you one chance. Stand by my side and share my magic, together we can rule this world and any other!
Or there's option number 2. Stand by your stupid friends and have your magic taken by force."
"We won't let you win!" Rainbow Dash shouted.
"We ain't stopping till Twilight's back to normal!" Added Applejack
"Our dear Twilight is nothing like you, you're a demon from her past that she's moved on from." Rarity said
"Yeah, so why don't you just stay gone!" Fluttershy yelled.
"We won't quit till Twilight is safe and happy again. And till you're down and out!" Yelled Pinkie.
The geodes glowed and their magic manifested into a rainbow of color which combined with Sunset's magic, Raising her into the air and transforming her into the form of Daydream Shimmer.
"If we must defeat you a thousand times, then we shall."
"STOP!" Yelled a familiar voice. Twilight had broken free from Midnight's control.
"What are you doing stupid girl! Stay back!"
"No! You're right, I am weak. But with my friends by my side I can be strong. You're a part of me, a part I wish I could be rid of, but one I can't deny. You're lonely, jealous even. You see all these relationships around you and wish it could be you instead of me. I feel sorry for you Midnight, you don't deserve to be mistreated because of one bad mistake, you might be a manifestation of magic but that doesn't make you evil. You have feeling just like anyone else. Well you won't control me any more. I choose to embrace your power, you are part of me, and you are a part of my world as much as any one of my friends."
Midnight Sparkle sobbed within Twilight's mind. "I was created by your innermost desires, I grew jealous that you achieved your goals and had gained a lover without my power. I wanted to help you, but I thought I had to take over for you to be happy. I'm sorry."
"It's ok, you'll never be alone again Midnight."
Twilight pushed Midnight Sparkle into her mind and returned to normal. Sunset doing the same.
"Sunset I'm so sorry, I saw everything she did and heard everything she had planned. She can't control me anymore. She's part of me and she always will be. But now at least I know she won't try to hurt you."
Twilight cried her eyes out embracing Sunset. Sunset hugged back.
"It's OK Twi, I knew from the minute we walked into your parent's house something was wrong. I knew it wasn't you and I knew I had to be careful. I admit I didn't expect her to control you without taking her own form, but I knew if she tried anything your body didn't want that you could stop her. I love you and I always will, you have your friends and most importantly you have me."
Sunset pulled Twilight's glasses off, wiped away her tears and kissed her passionately, the pair falling over onto the soft grass.
"I think that's our cue to leave wouldn't ya say gals?" Applejack noted.
The girls nodded in agreement and left for home again.
"Sunset, I think we should get home too. This last week has been memorable, and horrible. But I know these experiences have made us stronger not weaker. I'll always love you too."
Once the pair returned home Twilight walked up to Sunset rather nervously.
"Umm, Sunny. There's something I want to try with you."
"What's that Twi?"
"I-I think I'm finally ready. Ready for the next level of our relationship."
"Twilight, I know a lot has happened recently to bring us closer than ever, but are you absolutely sure?"
"I'm sure Sunset. I want this to be magical between us."
They climbed into bed together and sealed their night with a loving kiss, and an act reserved for those with a deep care and passion for each other.
