Twilight was reading books as usual. But she wasn’t absorbing and information, her mind was completely somewhere else. She had been thinking a lot about Rainbow. She just somehow lost her feelings to the pegasus, and she knew that marrying Rainbow would only be an extra burden in her life. A knock on the door disrupted her train of thought, she proceeded to open it, and it was none other then her very own mom.

“Hey mum, how are you.”

“I’m fine. How are you?”

Twilight just sighed as she gave a deadpan look at her mother.

“Okay, let’s go to the sofa.. and we will sit down.” She said as she led her daughter to the sofa. “Now, what’s happening with you?”

“Nothing much. Do you want some hay smoothie?”

Her mother just ignored that sentence. “What’s wrong, tell me.”

“I’m just not feeling too well today.”

“Why not?”

“I don’t love Rainbow anymore.”

This words shocked her mother, but she managed to keep her cool. “Why don’t you love her anymore? Tell me.”

“She’s so.. boring.”

“Well, you’ve known her for over five years. You’re engaged! You said you love her, she supports you, she provides for you, and darling you can’t support yourself. She’s a wonderful mare and she loves you very much. And she’s the assistant leader of the weather team in Ponyville! And she told me she plans to renovate your whole house.”

Twilight sighed at her naggy chanting. “That’s why she’s so boring.”

“Well, what are you going to do?”

“I don’t know... But I don’t mind her living with me.” She looked at her mother with a cheeky smile.

“You can’t do that. Have you talked to her about it?”

“No... I don’t know what to do.”

“Well, she’s a wonderful mare, and she’s going to be the leader of the weather team very soon. And she bought you a ring, clothes, whatever you wanted. Now you wanna dump her. That’s not right! I’ve always thought of her as my future daughter-in-law. You should marry Rainbow. She would be good for you.”

“But mum, I don’t know about this whole marriage thing. I mean after all, we’re both mares.”

“Twilight, let no lesbian feel discriminated. Black or white, stallion or mare, It’s all good!”

“I guess you’re right...”

“Twilight, I wasn’t born yesterday. I’m glad you listen to me. Nopony else listens to me, not even your filthy dad.”

“You’re probably right about that mum.” Twilight replied. Duh, who wants to listen to a naggy old hag like you.

“Well I’m glad you’re listening to your mother. Listen, I gotta go, but you remember what I told you okay? Bye bye now.” She said as she went out of the door.

“Thanks mum..” Twilight whispered in downright sarcasm. She left the house soon after, and headed off to Carousel Boutique.

She knocked on the door and it was opened by magic almost immediately. Rarity was standing behind, looking slightly surprised.

“Oh hello Twilight. What brings you here today?”

“Well, are you busy now Rarity? I would like to talk to you.”

“Well, I guess you could say I am free.. What do you want to talk about.” She said as they both walked in, and she used her magic to shut the door. They both took a seat on the couch.

“I just finished talking with my mum. She gave me this big lecture about Rainbow.”

Rarity gave her a slight nod, indicating she was actually listening.

“She’s a stupid bitch. She wants to control my life. I’m not gonna put up with that. I’m gonna do what I wanna do, and that’s it. What do you think I should do, Rarity?”

“Why do you ask me? You’ve been very happy with Rainbow. What do you want me to say? I mean you should enjoy your life. What’s the problem?” Rarity tried to calm her down.

“Maybe you’re right...” Twilight whispered softly as she opened her saddlebag and levitated two shot-glasses and a bottle of apple vodka.

Alcohol? That’s... unusual of Twilight...

She poured it in the glasses equally, serving one to Rarity.

“Erm thank you?” She said as she watched at Twilight sit closer and closer to her.

“Erm.. Twilight... What’s going on here?”

“I like you.. very much Rarity.” Twilight stared at Rarity with bedroom eyes.

“What are you doing this for?”

“What’s the matter? Don’t you like me? I’m your mare now...” she moaned in a tantalizing voice, stroking her mane slowly.

Rarity shoved her hoof aside. “Rainbow is my friend, and I will not betray her. And you two are getting married next month! I can’t do this...”

“Forget about Rainbow.” Twilight replied in a stern voice as she gently grabbed Rarity’s cheeks and pulled her face to face with herself. “This is between you.. and me.” She licked her lips.

“I don’t think so.. Twilight, we shouldn’t do this...” Rarity went to turn her face away in shame, but Twilight stopped her with a gentle touch of her hoof and brought her to make eye contact.

“Please don’t leave... please...” Twilight begged her. “I need you, Rarity. I love you. I don’t love Rainbow. And I don’t want to get married anymore. I dream about you. I need you to make love to me now, Rarity.”

Rarity was getting hotter and hotter under the gentle caressing of Twilight’’s soft hoof. But she still had her morals.

“I don’t think so... Everything is going to be fine, Twilight, I promise.”

The words fell on deaf ears as Twilight just pulled Rarity in for a wet, sloppy kiss. The raging hormones was overshadowing her morals now, as she let go of all forms of restrain and started to kiss back. Twilight’s kisses became suddenly more heated, and her tongue slipped up against Rarity’s lips. They kissed for minutes, and then moved to the staircase to continue their sexy time. The duo kissed, caressed and made love to each other for Celestia knows how long. Twilight had a lot of pent-up tension in her, despite having sex with Rainbow a day earlier.

It was after a few hours of endless orgasms and covering each other with fluids before Rarity realize the horror she had done.

“Oh Celestia... Why did you do this to me. Why? Rainbow’s my friend. I’ve betrayed her!”

“Didn’t you enjoy it?” Twilight looked at Rarity with a slightly dumbfounded look.

“I did.. But that’s not the point.”

“I love you, Rarity.”

“You’re very attractive. You’re beautiful. But we can’t do this anymore. I can’t hurt Rainbow.”

“I know. She’s your friend.”

“Hey. This will be our secret.” The guilt in her just suddenly disappeared as they proceeded to make out again.

“Again?” Twilight giggled as she teased Rarity, her hoof lightly stroking her flank.

They practically spent half the whole day having sex. After all, they did not have to worry about any pregnancy issues.
