Apple Bloom squeaked and stumbled backwards into a tree, gulping as she saw you approach her. There's a bit of a blush on her face as her eyes briefly wander over your body before she says "H~Hey s~stay back Missy uh... w~whatever you are! I~I'm not h~here to get uh, e~eaten or anything, I~I've got a job to do!"
You can smell that either the sight of your bulge, or perhaps your own musk softly seeping into the area, is messing with her a bit.
