I'm an old bloke (55) and just can't stop playing with my cock, i love it. Yesterday I was shopping at a large supermarket with my vibrating butt plug in and wearing pantyhose under my track pants. While cruising the isles i noticed a dirty looking young woman in shorts, knee high socks and a singlet, so naturally I followed behind her and rubbed my cock through my pants. I'd finished my shopping but decided to keep following her hoping I could spill my load while surrounded by other shoppers. Sure enough it didn't take long, i discreetly rubbed my cock while watching her and spilled my load inside my pantyhose and proceeded to the check out. By the time I reached my car my cum had leaked down to my foot.
