An Aussie bloke is certainly in the dog house with his girlfriend of 12 years after having a particularly public tryst with a random person he met on a train platform.

Everyone says love can pop up in the strangest of circumstances and this story is no different.

Shane Brennan was minding his own business while waiting for a train from Port Kembla to Wollongong when a woman approached him. She told him he was 'horny' but he fobbed off her advances. I can already see the Hollywood scripts being written.

The two individuals were on an empty carriage, seemingly enjoying their trip down south.

That was until the unnamed woman allegedly started masturbating in front of him and then one thing led to another and she ended up performing oral sex on him.

Once everything was done and dusted, so to speak, he poured a Coca-Cola on his privates to get it clean and he left the scene.

According to the Illawarra Mercury, there was a 'large and disgusting' liquid mess on the floor.

God, this love story is Oscar-worthy.

Unfortunately for him, CCTV cameras on the train captured the whole thing and authorities eventually caught up with him.

"I got a blowjob on the train and I was rinsing my cock off," he allegedly told officers who met him on the platform.

Brennan was booked for wilful and obscene exposure and offensive behaviour in a public place and had to go to court. That's never a good thing when you're trying to keep an affair from your long-time partner a secret.

His solicitor told the magistrate: "The facts speak for themselves...he took the opportunity that presented itself."

He plead guilty and copped a AUD$700 fine and was placed on a good behaviour bond.

But that's probably nothing compared to what he's getting from his girlfriend and mother of three of his kids.

Brennan has told the Daily Mail: "I'm in strife. She's not happy.

"I didn't know they had cameras all throughout the train. She was the one masturbating. If she didn't offer me nothing I wouldn't have fucking done it.

"I can't help myself."

Apparently when his girlfriend confronted him about it, he told her 'it is what it is'. You can't blame him for being honest.

Hilariously, in court, Brennan thought it wasn't an issue considering the train was empty, saying: "You'd think the train guard would've said 'good on ya, mate'."
