ive given road head several many times. It can be fun. there was one time my boyfriend at the time and I had sex while he was driving. in hindsight it probably wasnt the best idea, but it was a lot of fun. I was going down on him while he was driving my car and i climbed on top of him.
I have gotten road head a few times from my wife..It sure relaxes you on a long drive..and because of the positioning of her head I am almost guaranteed to finish in her mouth due to the 'clean up factor'.. If she wants to blow me while I am driving, she 'knows!" she is getting a mouthful..its kinda hard, reaching for tissues , etc..
Ii love giving road head because I can suck him for a long time. I mean where else is he going to go? Its a good position too because he usually puts his hand on the back of my head and drives it a little deeper in my throat
