Dad defends his cheating daughter by telling her bloke he wasn’t ‘man enough’… then tells him to get revenge by having sex with her FRIENDS

A SUSPICIOUS boyfriend got more than he bargained for when he tested his girlfriend's faithfulness.

She's caught on camera flirting with a stranger, agreeing to meet up and even passing on her number, to her boyfriend's horror.

His jaw drops as she's heard denying that she has a boyfriend and giggling as the stranger strokes her long blonde hair, as part of YouTube series To Catch A Cheater.

But even more devastating is the brutal reaction from her police officer dad, who's also watching the footage and gives some no-holds-barred advice.

Despite reassuring the boyfriend beforehand that he'll be fine, Officer Reynold's immediate response to the video is: "Definitely what I would is that I would be so p***** with her that I’d probably go and f*** every one of her girlfriends just to get back at her."

The stunned boyfriend says he's "not that type of person", so the dad offers some more helpful advice, including having better style, bigger muscles and "growing up".

"Evidently you don't have something she needs," he claims, as the boyfriend fights back tears.

The impatient dad then gets out his own rippling biceps, criticising the poor lad's physique and adding to his misery.

The presenter joins in the fun, grabbing at the boyfriend's biceps and showing off his own.

"You don't even know what you want to do," he adds, indifferent to heartbreak unfolding beside him.

The presenter then suggests he has the stranger continue texting the girl to see what happens, but his offer is quickly rejected.

All the boyfriend can bring himself to say is: "We're definitely having a talk."

On an earlier episode of To Catch A Cheater, a girl hired a porn star to pretend to seduce her boyfriend.
