It's been a few months since you've moved into a small Midwestern town, and had gotten acclimated to the resident high school's atmosphere. You maintain a generally cordial relationship with most of your classmates, especially the shy deer girl Noelle. You've heard that some of the others bully her, but you personally have always tried to be nice to her, simply out of the goodness of your heart...
One afternoon, as the final class for the day ends and you're packing your things, you find a small handwritten note in your backpack, signed by Noelle herself. In it, she thanks you for having always been kind and asks you to meet her behind the gym bleachers after school. Though somewhat hesitant, you decide to follow her request, and sneak in after hours – good thing the security has always been rather lax.
Eventually entering the spacious area behind the gym bleachers and looking around, you spot Noelle just barely hidden around a corner. But as she steps out, you immediately notice how... different she looks. The Noelle you know certainly never had such generous curves or... whatever that shape is, poking out underneath her robe.
Perhaps noticing your confusion, Noelle awkwardly laughs, showing her pair of prominent front teeth. "E-eheh, hi... I, um, cast a spell on myself and, uh, it made my body grow a bunch. I-it's my gift to you for always being nice to me, s-so please enjoy...!"
