Yes, one with changed breasts

You lick your lips slowly- it's pretty easy to figure out what this was, but you don't know how much you are able to use it. You decide to go easy to begin with- if this is a spell book, you want to make sure that using it doesn't somehow kill you. You flip to the page where the pictograms depict a change in breast size, the smaller breasts on the right. Thinking that maybe shrinking your already not-huge body features would provide you with more energy, you whispered the words on the page, sitting down on one of the benches to focus on the book.

You begin to read the book, slowly at first, but the words start to come easier and easier as it gets further into the sentence, your mouth seemingly working on its own to pronounce the foreign syllables. However, almost halfway through you seem to stumble, losing track of the strange rhythm that had been built up. tsaerb eht ecnahne, knirhs eht mid

Though you don't know why, the opposite effect of your expectation begins to take root, as your breasts begin to push outwards, the small mounds quickly growing to press tightly against the white fabric of your blouse. Within seconds, you lose the ability to question your situation, as your mind fades into a lesser state of concentration.

With a loud RIIIPPPP, your shirt tears down the middle, enlarged breasts pushing through. An unfamiliar weight on your chest, they're significantly larger than before, extending out at least half a foot from the rest of your body. Though it surely would have snapped, your lack of a bra simply means a pair of bare breasts, exposed to the outside world through the torn ruins of your top.

The book is still lying in your lap, open to the same page. Wondering whether you messed something up, you reach down to flip over the page and undo the spell, but as you flip through the book, you briefly forget what you're looking for, and it's enough to miss the page entirely. Page after page goes by, but all you can remember is that the page had something to do with you, but you have no idea why. Eventually, you reach the back of the book, and nothing looks familiar. In your confusion, you remember that your breasts are larger than they were before, without knowing why or what to do about it. Flipping the book back over, you rest it in your lap, trying to remember what you needed it for.
