I finally finish work and return in a nearly empty subway car. my cock is about to explode inside my pants. i get the idea of taking my dick out and cracking a handjob. i don't realize i'm doing it until i lower my head and see my fly open and my cock out. it is being one of my best jerks although any stranger can catch me. too bad that everything is so empty and that there is no one who wants to play with my cock for a while.
