Rarity And AppleJack
 
There’s not much to tell here. Rarity and AJ were connected and in love from an early age, but they were afraid to show it, but also knew that had support in their friends. It was only after the official wedding of Twilight and Celestia that mares came out of the proverbial wardrobe, realizing that this event opened the eyes of some conservatives.  
In their lives, however, it was not always colorful, they had one serious fall, in which Rarity went on a nearly one and a half year tour with a boutique, and AppleJack was in relationship with Rara.  
It was not easy for them, and as soon as they met, returned to each other - promising themselves faithfulness, and almost right away got married.  
Years passed and the loneliness of the mares grew slightly stronger. AJ has always dreamt of a house full of young foals bouncy here and there. Rarity was of a different opinion, however, and one representative of the house was sufficient for her. Eventually, after fervent discussions, they decided on two. Thanks to a potion recommended by Twilight, they managed to make two daughters.
 
CindyApple Curls.
 
Cindy, since the foal, she’s been spoiled by Rarity.  
“Wise, pretty and charming,”; said, telling about her daughter, mare even considered her to be an angel (she only lacks wings in appearance).  
Feeding on compliments and beauties, she grew into a cocky mare, confident of her high class and skills. The very conviction of being better than others made her a bully in the school of some younger ponies. Fortunately, she grew out of it.  
Thanks Party Thunder. This young pony didn’t care about her aggressive attempts to dominate or behave. All what he did was laughing, which made her angry. (she’s like a Heather, from musical)  
They finally made friends, and Cindy became a calm pupil, but unfortunately that didn’t change her opinion, but she didn’t care about it anymore.  
One could also expect a motif called “Teenager Romance”; which was in the mare by reading fan fiction. And that’s what happened.  
They fell in love, then got married and lived happily and long? No. During the school romance a group of Victorious Spirit*, Harrsha, Colorful Sadness, Burnt Noon and their two formed.  
As it is the case with young lovers, they were engaged in various sexual activities, but never expected that there would be “setback”. Cindy herself didn’t even know how it happened.  
After a night of passion, TP went to three months of flying training with Wonderbolts, and the mare attended school as usual when she realized that something was wrong. She turned out to be pregnant. Cindy was devastated and did not want to become a teenage mother, considering her school and future career.
 
In the end, she gathered courage and told her mothers about it, and these surprised her too - she will have a sister.  
At the end, they gave birth almost on the same day. But what a surprise it was when an ordinary white mare gave birth to alicorn. (Rarity thought she was cheating on TP with Victor [this big guy is still a virgin])
