GREAT story, very erotic !
Reminds me of all the times I used to commute on the elevated trains in chicago. The seating is basically the same except no bathrooms. Sitting in a forward facing aisle seat while the standees faced the windows so as to hold onto the straps. Many a time I'd have a hot suit standing right next to me, his crotch inches from my jaws and me holding up a newpaper while straining my eyes toward his bulge wishing he could just pull it out and feed me.
Thanks for the memories & the hardon !
