OT My 9 year old was looking up sexy images

Off topic! But I Just found out my 9 year old was looking up cowgirls then hot cowgirls and hot cowgirls kissing on google images.  I'm assuming she's just getting curious? I told her I would have a talk with her later, so I'm trying to figure out what to do or say. 
What would you all do in this situation? 
Thank you in advance
