You decide that F-cups are a bit much and set the light to local blue and point it at your chest and turn it on. Nothing happens.
You try again, still nothing.
You quickly set it to low intensity pink and point it at your hand, just to test that the flashlight hasn't broken. It works perfectly. You quickly change your hand back to normal.
You try to shrink your boobs again. Nothing.
You spend several minutes racking your brain over what could be wrong with the light. It dawns on you that breasts are now gender neutral and you are stuck with yours.
Unsure of what to do next you step back into your bathroom, and notice that there is now a bra on the floor from when you hurriedly undressed earlier, it's sitting in puddle of water from your morning shower. You look yourself over in the mirror for a few minutes. You feel the weight of your breasts pulling at your shoulders and back, regretting making them so large, you briefly wonder what women think of men's breasts in this reality. Are they as interested in men's chests as men were in theirs? Are men still that interested in breasts? You seem to be. Looking at yourself again you decide showing cleavage is a bit much for your first experience with the new situation and change your top to a plain T-Shirt, you notice that the shirt is cut with more room in the chest area to allow for boobs.
The T-Shirt is quite tight around your breasts, but it otherwise fits perfectly, and the unfamiliar sensation of wearing a bra is uncomfortable, but you decide you probably need one and had best get used to it, and given the fit of your shirt it's likely that your bust size when you used the "global" setting wasn't a factor for anyone else, so you're boobs are just as unusually large on you now as they would have been on a woman before.
You look at some of your other shirts, some of them are too big everywhere but the chest, others are like the tee you are wearing. You remember your girlfriend complaining about having this problem, though from the fit of your shirt you probably have it a bit worse than she does.
You pick up a larger T-shirt, and put it on instead, it fits around your chest more comfortably, but hangs loose everywhere else. You decide this shirt is for relaxing at home, not going anywhere since you don't like the baggy look, and change back into the tighter one.
You wonder about the "Tits, mine are bigger!" on your bra, it doesn't seem like the kind of thing you would want on your underwear, perhaps you girlfriend got this bra for you as a joke? Or one of your friends? Either way it seems to be the only one that's clean since the one you had on earlier is wet. You don't want to go out with no bra as even unaroused your nipples would be obvious through your shirt.
You snap back to reality and decide you have to something other than just wander around your dorm looking at clothes and daydreaming about what's different. You think perhaps you should try to work out what else is different, either by going out into the world, or perhaps looking up some biology on the internet.
