Yeah. Definitely looks like she got beat up really bad, or fell or something like that..
Actually the first thought I had was that she was in some sort of Master/Slave relationship and had been punished. Don't ask me why, I don't know.. I guess because they'd be usually hidden by pants so no one at work would know, or something.. *shrug*
And yeah, I think that the contrast between extremely thin waist and huuuuge rear might be what gets certain sorts off, don't you think?
