Having a jerk whilie working on a customer’s house on my lun.. (OnlyFans)

Having a jerk whilie working on a customer’s house on my lunch break, 

I was turned on all morning when a plumber arrived on the job to check the boiler, he had a massive bulge in his work trousers you could see the full outline of his big fat cock squashed down one side! 
It felt amazing cumming behind the door knowing he was just on the other side. 
This is my favourite thing to do when there is a hot guy around. 
What would you guys do???
