Controversy erupted Monday at an area sex farm/white slavery compound when second-grader Tim Hildemen was expelled for refusing to felch a llama. 'This kind of inhibited behavior is totally inappropriate for our sex farm,' sex farm commandant Henry Prathers said. The felching incident was to be part of a group-sex video produced by the compound leaders. Hildemen, 7, will be blindfolded, then driven in the sex-farm van to an undisclosed locale and pushed out. Summing up the reaction of an outraged community, mother Ellen Mayes said: 'What kind of message does Tim's behavior send to other kids?'
