In excitement, the boy showed the sex video to friends and made it to scores of others.
He used his mobile phone to capture the episode and is now said to be a celebrity in the neighborhood.
"The boy piped through a window and caught his parents hitting it out," said a source in Pumula South.
Sources say a report was made to the social welfare department, but probation officer Qalani Nhliziyo says they have not received any such report.
