A lecturer has been accused of going way over the top while teaching students about safe sex - after demonstrating how to put a condom on with her mouth.
Footage of the woman getting on her knees and putting the condom on a plastic penis held by a shell-shocked male pupil has provoked outrage after it emerged in Brazil.
His classmates rolled around with laughter as the X-rated practical demonstration was carried out.
It is believed to have been filmed at a university in Bahia, in the north east of the South American country, but this has not been confirmed.
No-one in the classroom looked particularly shocked as the brunette showed her seeming expertise with the questionable demonstration.
