Cheeky!!! Guys pissed off and then blowjobed

When I was out on the Alz the other day I had to pee urgently but some young guy was sitting on the stairs downstairs and didn't want to let me pass because he was on the phone. Well laugh if he wouldn't let me pass I thought to myself then you just piss on his back lol which I did. At first he was a bit taken aback but then he really liked it. He said I should give him another blowjob as compensation. Since I like to blow anyway, that was easy for me. But with all the peeping toms, he didn't even get a really hard one. And so I just left him with a `so that's enough` and left. How would you have reacted?
