I know you are being facetious, BUT...
Serious Talk!
If the choice would be Isa's boobs or Isa, Alex's boobs or Alex. Even with this being a "porn" story, I would tel you to take the bewbs. Yeah, they are AWESOME, I love those globes of fat to the moon and back, but, Isa and Alex are way more than just globes of fat carriers. So! Save the girls, kill the bewbs if you MUST. I would love them with or without bewbs.
Oh I would cry with them over the fucking loss, then I would dry the tears open a few bottles of bubbles, and toast their lives for 2 days straight. Then we would look together for whatever prosthetics would help them recover their self-image.
Love has many facets, perfection isn't one of them.
Peace
