A Catholic school teacher in Colombia was left red-faced after forgetting to turn off a Zoom call with his class of teenage students before snuggling up to his wife's breasts.
Ruben Dario Parras didn't realise he was being filmed as he lifted up his wife's blouse.
The physics tutor then appeared to kiss her left breast as the moment was broadcast to everyone on the call.
He was forced to apologise after inadvertently sharing the moment with the class of 16 and 17-year-old pupils.
One of the students at the Educación Educativa San Vicente de Paul Catholic school, in Palmira, Colombia, can be heard sniggering as she watches.
She then says 'Oh my God' and cringes as her teacher canoodles with his wife.
Shamefaced Mr Parras made an embarrassing video apology after the blunder.
He said: 'Some images were recorded while my wife came in to greet me that have gone viral on the web.
'Of course it was a mistake of mine, as I didn't realise the camera was still switched on at the end of class.
'At no moment did I do this deliberately. It was accidental.
'I want to apologise for causing offence.'
Headteacher Patricia Duran Cespedes has launched an investigation into the incident.
She said: 'This was a serious matter in which the teacher in charge of the class performed an inappropriate act which was recorded by some students.
'And was later viralized on social media.'
One viewer - called Lapaty - joked: 'It looks like his wife isn't enjoying the breast sucking very much. Poor bloke, now all the world knows his wife is barely interested.'
Pipe Dorado added: 'I feel sad looking at his wife's face. There's no feeling at all in her body. Or does the prof need a lesson in breast sucking?'
But Fanny Cardona stuck up for him and said: 'People are human. They make mistakes. He forgot about the camera, but he's at home and he can do what he likes.'
