You approach the car with someone inside

Getting help from someone seems like the most reasonable thing to do in your situation, so that's what you're going to do. You see a silhouette of a man sitting in the car as you approach it.

You approach the car from the side and only once you're already standing next to it you see the man sitting inside. To your shock you see that he has his dick out of his pants and he's slowly jerking it. You realize that he's likely been watching you all the way since you exited the van. It seems like you've just found your way from one pervert to another.

You're not sure if asking him for help is such a good idea after all. What do you do?
