I LOVE THIS KID! Hopefully he stayed between the lines. You do need to educate him that not all nipples are pink (my favorite on a woman) some are brown, some are a softer peach shade. Did he also color in the va-jay-jays and the bung holes or did you catch him before he got to that portion of your "artistic anatomy reference books"?

Report it to the library that as you were looking through it that you noticed they were colored in and that you dont want to get charged for something someone else did!!! lol

that's hilarious ! (:

He was filling in the blanks

Ouch. O_O Anatomy reference books are some of the most expensive out there, and they'll probably make you pay. FYL.

Why was your little brother looking at a book with naked people in it ???? : /

At least the color is right, at least for white people.

Where are his parents??

If you wait 7 years, those books can be yours to keep.

I'd be more concerned if he was drawing balls & facial/chest hair on the female drawings, & consequently, breasts & snappers on the fellas!
