I was never into exhibitionism, in fact, I was always very careful about privacy, until one day I was being blown at a friend's apartment. I was sitting on the sofa and he was kneeing in front of me. Outside, there were two workmen on scaffolding repointing the bricks on the building. They were focused on their work, and not looking into the window. All of a sudden, I was overcome with a strong desire to have them watch us. I waited until their power tools stopped running for a minute, and I made a loud noise to get their attention. One of them looked at us, and then got his buddy's attention to look, too. I put my hand on the back of my friend's head and got more aggressive with him. Nothing bad, just a little more dominant. I winked at the guys. The guy closer to window was just watching, holding his power tool (LOL), and the guy behind him was touching his growing bulge. I usually last a long time, but being watched was so hot, it didn't take me long. I blew a load into my friend's mouth and immediately leaned forward to kiss him and share the cum load with him. I angled my head to make sure I made eye contact with the guys outside the window. Still one of the hottest things I've ever done.
