Twilight was an ass woman. She liked butts. Big. Small. Round. Wide. Toned. Fat. She was an ass connoisseur. The number of pictures she had on her computer of women's rear ends was embarrassingly large.
Which is why Rarity really needed to stop wearing skintight skirts and bending over right in front of her. Rarity's ass was fantastic. One of the best she'd ever seen, and certainly the finest in the school. And the way she kept flaunting it was driving Twilight near to madness.
It increasingly seemed to Twilight that Rarity was inventing excuses to bend over in front of her. Constant dropped pencils and lipstick and other assorted items that she seemed to take wayyyy too much time picking up. Rarity would constantly pick a spot in front of her for yoga in gym. Twilight didn't know if Rarity was teasing her or flirting with her or what but something had to give before Twilight gave into her growing desire to give that perfect rump a smack.
Things finally got out of hand one afternoon at the mall. Rarity had dragged her there, alone, mostly to try on clothes and get Twilight's thoughts. Which really, really didn't help keep Twilight's libido in control. Once again she had managed to squeeze her big round booty into one of the tight pencil skirts she loved so much.
"What do you think Twilight? Does my butt look good in this?" Rarity said, turning to show off said asset to one of her best friends and loyal confidants.
Of course, it did. It looked absolutely delectable. But she sure wasn't going to say that. Her palms were sweaty and her stomach was doing flips. She felt disheveled and awful.
"I...uh...I don't know." Twilight said in a squeak that would give Fluttershy a run for her money. She had averted her gaze as soon as Rarity had asked the question, and was now looking at the floor.
"What was that dear?" Rarity asked.
"I...uh...don't know." Twilight said, speaking a little louder.
"Oh, come on now darling. Surely, you have some opinion." Rarity said.
"I uh...really don't. I-I'm not that into fashion really." Twilight said.
"Oh, I know dear. But I do know your into women's behinds. So please, opinion." Rarity said, ending in a sing-song.
For a moment Twilight's heart stopped. Then it dropped. Did she really just hear that?
"I...Uh...I...I do-don't..." Twilight stuttered. She didn't know what to say. She didn't want to incriminate herself, but she also didn't have any sort of rational response or rebuttal, her mind had gone completely blank.
Suddenly she felt a hand on her cheek, pushing her face so that she was looking into Rarity's eyes.
"It's ok darling. You don't need to be so nervous. It's fine. We all have our preferences darling." Rarity said. The other woman was so close to her. So tantalizingly close. Twilight could so easily just move forward and kiss her.
"I...I..." Twilight said. Her nerves for some reason had calmed a bit. Something about her big blue eyes was soothing. And the gentle tone of her voice, even though she could barely process what she was saying.
"I, for example, quite appreciate your cute little tush." Rarity said, underlining her point by grabbing the aforementioned bottom tightly. Twilight gasped, followed by a squeak that was caused by a much more pleasant emotion. Arousal.
"So please, Twilight, be calm. No one here is judging you." Rarity said, her fingers brushing Twilight's blushing cheek.
"I...I..." Twilight stopped and took a deep breath. Rarity wasn't judging her. Not at all. And she seemed to actually...like her. In more than just a friendly way, perhaps. So she really needed to woman up here.
"Ok." Twilight said.
"Good." Rarity said, releasing her grasp on both Twilight's face and her bottom and gave Twilight an encouraging smile. Then again she turned around, giving Twilight a good look at her huge tush.
"So, how does my derriere look in this skirt?" Rarity asked.
"It...it looks fantastic." Twilight said, still a bit nervous.
Rarity smirked. This had been quite the productive shopping trip already.
