Tried it a couple times. I have a friend who does it alot and talks about it pretty freely. The man is freakin hot too. His talking about it made me curious and pretty turned on. A couple times, after hearing about it, I attempted on my drive home. Not very successful. I'm not worried about being seen, just worried about my concentration. I just want ti badly to focus on either my cock or the road so it doesn't work out to well.
