A kink centered around arousal from the process of a penis growing or becoming erect. The focus is on the act of growth itself, not necessarily the final size. For some, this includes realistic depictions of getting hard, while for others it expands (literally) into fictional or animated scenarios where the erection continues growing beyond natural limits in a controlled or sensual way. Often overlaps with transformation or inflation fantasies, but centers specifically on the phallic expansion.
