When I was a freshman in high school we had to sell raffle tickets to raise money for the school. After a few hours, I rang the doorbell of this house and an older man in his 60's appeared in his robe. I asked him if he wanted to buy some tickets for our school and what happened next shocked me.
He squatted down and his robe parted revealing a huge old cock! His pubic hair was gray and his dick was the thickest and longest thing I'd ever seen. He saw me looking at it an pulled it out . . . pulling on it until it stiffened.
He held up his dick towards me and said, 'I'll make you a deal. I'll buy a whole book of tickets if you touch me.' I thought, what the heck and reached out and put my hand around the girth of his dick and pulled it upwards. He winced a little and said, 'gentle, gentle.' I really wasn't interested in doing anything more so I let go and told him the book was $5.00. He excused himself, found his wallet and bought the book just as he promised. Later, in the privacy of my bedroom, I jacked off just thinking about the size of his dong.
I know now this guy was a pervert and he shouldn't have done that; but what the heck, I wasn't harmed by it. Fascinated, yes; harmed no.
