This just happened to me recently, i was with one of my new plates, we haven't done anything sexual yet but, yesterday i was in the car with her, i was trying to kiss her and tease her, doing the regular stuff but while i was in the process she was just talking too much about "we're going to fast, she can't do this and that cause just met, ect" and that was kind of turning me off, ShitTestAlert, men i didn't let that happen, and just without thinking about it too much i took out my dick and just like magic she started sucking the "vitamine C" (My cock lol), after a few mins( i couldn't believe it) i said "don't let anything drop in the car, swallow it" and she continued her job, is just about focusing on what it is that you want and make it happen, let them know what you want and don't think about it too much
