LYNNWOOD, Wash., May 5 (UPI) -- A Washington mother with a teenage son said she was outraged to find books with sexual content on sale at the teen clothing store Urban Outfitters.

Marci Milfs of Lynnwood said she plans to file a complaint with the city of Lynnwood about the books, which she said do not belong in a clothing store aimed at children and teenagers, the Everett (Wash.) Herald reported Monday.

Milfs said she has already raised the issue of the books -- which include "Pornogami: A Guide to the Ancient Art of Paper-Folding for Adults," and "Porn for Women," a book featuring pictures of men doing housework -- with state Rep. Norma Smith, R-Clinton, and conservative non-profits including Morality in Media, Concerned Women of America and the American Family Association.

The mother said Urban Outfitters' corporate office in Philadelphia refused her demand that the books be removed.

"They said they are not sex books or pornography books, but that they are art books and their goals are to support artists," Milfs said.

However, Milfs maintains the books should not be seen by children.

"It's not freedom of speech," she said. "It's selling adult books to teenagers."
