I think El Diablos idea of a 10 is a generic Vegas skank with fake tits, ass injection, etc.
10s almost do not exist. You're lucky if you see a 9 from time to time...still not likely.
If she has fake tits, she can never be more than an 8...as a general rule.
Being a connasuer of much porn...I have to flip through pages, just to get an 8. There's no way you're seeing 10s or 9s. Maybe you were drunk and forgetting the tits were fake and under that dress was a Caitlyn Jenner special waiting for her/his man later that night.
Vegas is filled with skanks. I see a lot of women in Vegas...honestly, not many are that hot. More delusional and fake. California, still a bit of fake...but a ton better. Maybe you were seeing tourists though, so they could be foreign. A lot of foreign tourists have money, no shock...therefore the higher pussy quality. It's not because they're skinny with tats.
