“Sandrine” on Flickr

As per usual when our friends at Touche Sexy inform us about yet another amateur hottie they've discovered, we're not able to tell you much about Sandrine here aside from the fact that she's a 23 year old French girl studying physics at university*—and apparently, part of her research involves experimenting with the density and mass of her copious and rather perfect boobage, which she demonstrates in hundreds of naked solo shots in her Flickr photostream. If only all our science classes in school were this enlightening.

*Update Thanks to the several readers who wrote in to say that "Sandrine" looks an awful lot like former Playboy and Perfect 10 glamour model Trisha Campbell; we should've known that a real French physics student would be too busy studying to have time to take her clothes off that much. Guess we were blinded by all that mad science she was dropping.
