What's that circle-lines-thing in the lower part on her left leg?

A vagina symbol.

Right Leg: 千ンポ大好キ
Left Leg: ヤりマン
Stomach: 人れて
Under right boob: ?
Under left boob: 肉便器
Right boob: 黒スｷﾞ
Left boob: 肉ドレイ

None of this makes sense, probably b/c I haven't played whatever game this is from......

Right Leg: 千ンポ大好キ - loves penis
Left Leg: ヤりマン - easy woman (more like slut, I guess)
Stomach: 人れて - put it in
Under right boob: 豚 - pig, usually written as 雌豚 for female pig
Under left boob: 肉便器 - meat toilet
Right boob: 黒スｷﾞ - too black (not sure on this one, but 腹が黒い means black-hearted/evil)
Left boob: 肉ドレイ - slave

Standard(?) derogatory sex talk.

I don't think that's the problem, except perhaps for 黒スギ.

Perhaps they're commenting on how her nipples are "too dark" (where Asians have darker ones, as opposed to the more "pink" nipples Caucasians have).

this be a dumb question....whats the vagina symbol for?... and why is it on her left thigh?

It's humiliation, man. It's sort of saying "Think of her as nothing more than some hole to fuck."

weird censorship. her pussy is censored diffrently from the dude's dick.

Photoshopped censorship?
