I'm surprised no one brought this up... She's always been self conscious of her puffy nipples, I'm guessing this is the main reason behind the surgery and the "I'm doing this for me" thing. I'm sure the husband ain't complaining tho.
Also, lots of normal (non-of / influencer) gym girls eventually get fake tits because they lose theirs when their body fat gets low. She didn't start with much, but she did have more before than the recent years.
Maybe I'm too jaded to think this girl that seems very vanilla is doing it all for the gooner money.
