The next morning, you wake up feeling refreshed. Something seems a little off to you, though, and you try to figure out what it is. Suddenly you remember the flashlight and quickly look in your bag, but it's still where you hid it. Unless . . . what if Eric DID find it and just re-hid it?
You quickly look over your body, searching for any sign the flashlight has been used on you. To your immense relief, everything looks normal - you're still fully female. The only thing that seems out of place is your chest; you're not wearing a bra, which is somewhat strange considering you're sleeping in a tent with two guys. But you remember it being a warm night, so you probably just took it off while you were half-asleep and feeling too hot. Besides, your boobs aren't all that big, anyway.
Thinking about your boobs, you realize something. Like most girls, you've always been a little unsatisfied with their size; unlike most girls, you can actually do something about it. With a quick furtive glance at the guys - both of whom are sleeping - you pull out the flashlight and shine the pink beam on your chest.
You instantly feel your shirt tighten as your boobs begin to grow. The nipples become even more defined through the thin material as they enlarge and stiffen with pleasure. You breathe faster at the effects of the change but keep the light focused on your chest as it swells into the C-cup range. Finally you stop, not wanting to go too far.
Unfortunately for you, it is already too far. By shining the light on your chest, you have changed reality for everyone else. This includes Eric - the only one who had known you were supposed to be a guy - who now knows you have had eye-catching C-cup breasts since puberty.
