I start off flexing a little.. showing how the sleeves are tight.. but the rest of the shirt is loose, especially in the chest area . My breasts begin to expand, as if they're balloons being filled with air. with each breath they begin to get bigger and bigger, pressing up against the shirt, pushing the buttons to burst off. It's a little frustrating.. they want to break free from this blouse, and there is a struggle of breast vs. shirt.. that is growing so tight. Finally, the top button breaks free, my breasts their way through the fabric and continue pec flexing and expanding
