You walk into the restricted section in the library and I tell you that you are definitely not supposed to be in here. We get talking and you ask me about my biggest fantasy as a Librarian. I explain that I always thought it would be hot to have a stranger walk into the restricted section, I get on my knees and give him a blowjob and never see him again. You pull down your trousers and I take your cock into my mouth.... ;)
