You breathe a sigh of relief when you realize Gene didn't actually hit you with the light. Of course, what you don't realize is that when he hit you, reality changed for you. When the light hit your chest it reduced your breast size by a cup but created a reality for you in which you had always had breasts - even though you still remember turning the rest of your body feminine with the light.
"Would you quit playing around with that thing?" you demand. It's a bit unfair, of course, since you were playing with it yourself, but you don't want Gene changing you without your knowledge.
"Fine, I'll change you back," Gene mutters, finding the pink setting and bathing your chest when you aren't looking. To him, of course, you have always had D-cup breasts (along with the rest of your female body), so this does seem like changing you back. Since you're not holding the flashlight, though, it again changes reality for you and now you also remember always having D-cup breasts - something that was always a struggle growing up as a guy.
"Let's just go back the the dorm," you say, turning in that direction. "We can sort things out once we get there." Secretly, you're hoping to have an opportunity to steal the flashlight back and turn your body back to normal before anything gets out of hand.
