24 years old czech babe Petra Nemcova is really looking the best she has in quite some time. I got here some nice pictures which include a bit of a Petra Nemcova nipple slip! She was featured on the cover of the 2003 Sports Illustrated Swimsuit Issue but appeared also in the editions of 2001, 2003, 2004, 2005 and 2006. She has also modeled for Victoria’s Secret, and for many other companies in the women’s clothing market.
