Repair vs fuck. cum explosion

I borrow a car and what happens? My exhaust falls off. Great, that's all I need. That's going to be expensive. Luckily, a guy came by who also happened to be a car mechanic and offered to help me straight away. As blokes are, he also had an idea of how I could pay for his help. So off to the toilet, cock out and off we went. After he had fucked me thoroughly, he squirted his load all over my bladder. OMG... what was that now? The total cum explosion
