he thinks a 15-year-old girl is inside ready to have sex with him. >> oh, you made it. come on in. just getting some laundry out. >> his screen name is too graphic to use. in the chat he asks the decoy, when it comes to sex, is there any position you like best? the person pretending to be the 15-year-old says, i only did the one. he says, we'll try others. when the decoy said it's awesome he's bringing the big truck. he says, i don't want your mom finding out. because it would mess up a good thing. >> that's a big truck you got. how you drive that thing? >> it's like driving a car. >> i would love to go for a ride sometime. >> i'd love taking you. >> where exactly were you going to take her in that truck of yours? >> i was going to see certain places. >> like where? >> she just wanted to go for a ride. i'll take her for a ride. i didn't mean no harm or try to do nothing i shouldn't be doing. not trying to be no idiot or pervert.
