Rarity has always considered herself an attractive mare. But when Twilight asks her to help test a magical artifact purported to make ponies bigger, the petite Rarity finds it hard to turn down the opportunity. Just a few inches, she tells herself - enough to look Twilight, or perhaps even Spike in the eye. But as a few inches of height becomes a few feet, she finds it difficult to resist the promise of more - especially as some of the more sensual effects of Twilight's tests fuel her ego and libido beyond anything she's felt before.
