Swell

Swell is Buster's second book of breast expansion sequences.

Our breast expansion sequences begin with clothed women possessing small, average, or a bit bigger-than-average sized breasts, but then experiencing miraculous growth that transforms them into big-breasted dreamgirls! Several result in exposed nipples or areolas courtesy wardrobe malfunctions as the expanded endowments burst forth. There's quite a bit of cloth stretching.

These comics contain sexual themes. There are ten total expansion sequences.
