What happens a lot with girls in the sex industry is they join because they're insecure and need sexual validation, then they get money, and instead of using the money for therapy, they use it for cosmetic procedures that will "fix" the stuff they've always felt bad about themselves. There was a call girl in my area, never went out with her but saw her ad, absolutely stunning, the kind of girl you only see in magazine covers. But she had thin lips and very small boobs, again, STUNNING, but probably always felt insecure about it. Now she has the mouth of a blow-up doll, and those awful spherical plastic tits. She looks terrible. Ironically, 1h with her now costs double of what it used to.
Lauren was always a 7 at best, but a fun 7, the kind of girl you'd be glad to both fuck and hang out with. But because she knows she's definitely not a 9 or a 10, she's using the money she's making from the guys who're happy to see her tits once a week to "fix" the things that aren't wrong. I wouldn't be surprised if she got a boob job, or a liposuction in the near future.
Anyway, Harriet has always been hotter.
