Rarity had a big butt. Stereotypically this should concern a feminine fashion-focused woman such as herself. However, in addition to this being an overbroad, comical cliche, this was the 21st century and Rarity was an individual. An individual that quite enjoyed her large backside. How it looked in skirts and jeans and dresses, in more intimate apparel like underwear or lingerie, and just plain nude. And she enjoyed the positive attention she received for it. Men, women, it made no matter, she just appreciated that it was appreciated.
She identified with it a little bit. Not overly and to an unhealthy degree. She liked being a fashionista, an avid reader (particularly of detective/mystery and romance novels), an element of harmony and everything else she was. But she also liked being the girl with the big booty who loved to show it off every now and then.
Part of it, she supposed, was due to her healthy appreciation of her own body. She would often, maybe once or twice a weak, stand in front of her full-length mirror, naked or in her underwear and really...appreciated herself. This was different then her usual masturbation sessions. In fact, it would almost never start out with the intention of resulting in masturbation. She'd just find herself tempted to give herself a good look over or to see if she still liked the way a particular underwear set looked on her.
Her face, she considered to be a work of art. This was not entirely vanity, at least not of the physical kind, she put a lot of work into how her face looked through careful application of makeup and lotions and moisturizer. Her face was pretty enough even without the makeup, it wasn't about that. It was about expressing herself. And to a certain extent, controlling how the world thought about her. She particularly liked her lips, which were soft and pouty. She enjoyed blowing kisses into the mirror, but when she was really appreciating herself, she would kiss the mirror, leaving it covered in lipstick stains she would have to wipe up later.
Her breasts she thought were just the right size. Perky B cups that allowed her to wear a diverse array of dresses and tops without seeming too immodest. Sure it "unbalanced" her body a bit, being much bigger on bottom than on top, but she hardly minded. Big breasts had their appeal, but personally, she preferred smaller boobs. The old adage, "more then a handful is a waste" came to mind. She would take her soft breasts in her hand and fondle them. Even to her own hands, they felt good. And of course, the sight of her pretty face in the mirror, contorting in pleasure as she touched herself only aroused her further.
Her ass she couldn't always get perfect views of in the mirror. Which was why she had the photos. When she was truly appreciating herself, those photos were vital. She just couldn't get herself off without it. She didn't want those pictures just lying around, so she put them in a box tucked away in her closet. Whenever she needed them, she'd take them out and pin them to the mirror, and she'd touch herself until she reached orgasm to those pictures and her breasts and her frame and her pretty face contorting in ecstasy.
Rarity knew this wasn't entirely normal. However, she didn't give it too much thought. She simply thought that it was a self-esteem booster, a form of self-care that went beyond simple masturbation or talking oneself up. She honestly believed it would do people some good to do this regularly. Though again, it didn't rise to the level of obsession. She rarely thought about this until after she had done such appreciation sessions.
Her other masturbation sessions were hardly as narcissistic as her appreciation sessions. She thought, these days at least, largely of Twilight. A woman whose form, while a bit less curvy, was a match for hers. Though she often thought of themselves in threesomes or moresomes with their other friends, crushes that Rarity had, and the occasional celebrity or porn star that Rarity was particularly fascinated with.
She was getting closer, Rarity knew, she was getting closer and closer to seducing Twilight and she longed for that day. She knew though that she couldn't rush it. She had to take it slowly. Otherwise, she could lose everything.
And she wasn't going to lose to anybody.
