Ty wished himself unnoticeable and walks into the changing room of a lingerie store. Still being unnoticeable he waited around a little bit then wished someone would come into the changing room. Then a girl came inside, she was a cute girl of probably 14. Her chest was a small thing of probably just an A-cup. Her figure was a boyish stick though and Ty thought of an idea. He put some buttons on the side of the mirror from top to bottom labeled 0, A, B, C, D, E and made the girl notice. This was the girl's first time in a changing room for lingerie and came in with a few different bras and panties to try out. She put on a frilly pink bra and pantie and looked in the mirror and seeing how they looked on her. Not a lot to check out but she was curious about the buttons. She first pressed the 0 button and her A-cup breasts flattened into her chest leaving her with a completely flat chest and a flat bra. A bit nervous she pressed the A button and her breasts reinflated. The girl thought for a second and then went directly for the E button. As expected her breasts swelled up to an E-cup and the bra stretched to a comfortable fit. Enjoying herself the girl put her normal clothes back on (fitting somehow as well) and left.
