Massively busty blouse button popping

Wearing a very tight K cup bra, I try-on two outgrown button-up blouses. Almost immediately, buttons start flying off my blouse startling me a little. I am visibly roused and like how easy it was to pop all those buttons simply by relaxing and letting the massive weight of my breasts push onto to already strained buttons so I continue popping my off the shirt. Once finished with the first blouse, I squeeze my enormous breasts into another tight blouse and try to fasten all the buttons without destroying the shirt too early. After having easily taken care of the second shirt's buttons, I continue ripping the shirt itself. Pushing and thrusting my giant boobs through the fabric and giggling about it. At the end, I stuff my shirt into my blue lacy bra. This is a custom!
