Do you think if I ask a straight male for sex they would do it?

I have a crush on my school bus driver, he doesn't seem gay, he probably has kids and a wife and i am much younger than him but im curious of the chance of me actually doing it with him. I know its possible so thats why i want to do it. I want to ask him if hes down for some but what could be the worse outcome you think? Have you done anything similar with teachers or anyone else? Its my biggest fantasy. Would he kindly say no? I have no idea
