Having avoided a crisis, you decide to hide the flashlight until the weekend is over. You don't see Eric carefully watching you, so you easily fall asleep that night without realizing that he's just biding his time.
Once your breathing is even and you are fully asleep, Eric carefully sneaks into your alcove and retrieves the flashlight from its hidden spot in your bag. At first he just tries to see if it works; turning it on, he bathes the clothes in your bag with a pink glow. He grins as he watches your shorts transform into short shorts, your boxers become panties, and your undershirts become bras. Still thinking the light changes just clothing, Eric points it at your sleeping form.
At first, Eric sees what he expects - your boxers shrivel down into panties tight against your bulge. Then that bulge begins to shrink, even as your hips suddenly widen into an hourglasss contour and your upper thighs - the are affected by the current beam - become smooth and soft. Eric stares in amazement, neglecting to turn off the light until your "package" has completely disappeared.
