Would you have said no?

I was out and about with my boyfriend and we wanted to have a really romantic evening. We were going to go out for a nice meal and then let the evening end on a hot note. I had packed my boyfriend because he really likes it when I do it to myself. When we were both travelling in the car, he saw my dildo in my bag. Of course, he immediately wanted to know why I'd taken it with me and got all nervous. I told him that it was for the evening but suddenly he said that he wanted to see it in action now. So I took my trousers off during the car journey and started to get it. He didn't know where to look first, at the road or at my wet pussy...
