Dressing Room Growth Spurt (Patreon)

It all started when I was in the dressing room, trying on this cute white button-up shirt. The moment I slipped it on, the air suddenly felt too warm. Sweat started beading along my neck and between my breasts almost immediately. I figured the room was just poorly ventilated… until I looked down.

My hands moved on their own, pressing against the front of the shirt. They felt heavier than they should have. Fuller. The fabric was already pulling tight across them, and I could feel a slow, steady pressure building underneath my palms. My heart started racing.

I grabbed the collar with both hands, trying to give myself space, but it only made things worse. The buttons strained harder. The thin white fabric clung to every curve, turning almost see-through from the heat and sweat. I watched in the mirror as they kept swelling, pushing outward, forcing the shirt open between the buttons. There was nothing I could do but stand there, wide-eyed, feeling them grow heavier by the second.
