The Long Train Home (Patreon)

The growth started unnoticeable, but she still felt something amiss. By noon, an awkward pain rested in her chest. Right away, she realized what the pain was; something she hadn't felt since puberty. She wondered if she was having a growth spurt or a type of second blossoming. Still, she soldiered on with the work day. However, she realized she could now see the manifestation of her discomfort. Her shirt visibly was being stretched, and by the time the work day ended, she realized her shirt was beginning to strain. Between the safety of home and potentially being caught without fitting shirt was the subway ride.  She found a secluded section, void of other passengers. She sat down, and with a snap, her shirt unbuttoned itself.  Hanging freely, her enlarging breasts pull at her shoulders. Behind her, she hears the front car's door open. Embarrassed, she grabs at her chest, fruitlessly motioning for their growth to reverse.
