Just throwing this sequence on here which I recently made for Tabykat it is furry related featuring his OC Tabytha, but contains Breast expansion with popping.
The premise is Tabytha injects a questionable subtance into her breast implants which she uses way more than the approved dosage. This leads to her breast implants expanding out of control with saline till they eventually burst.
Part 1
Part 2 (Popping)
