Son Discovered Masturbation

Many years ago, I raised two sons. I remember when my youngest son was hit hard by puberty. I went into the bathroom with fresh towels while he was in the shower. I shouldn't have, but I could see him thru the shower doors. I watched him stroking himself before his hips buckled as he obviously had and orgasm. I sneaked out quietly.

The next evening while we were watching TV, I came right out and asked him how long he had been masturbating. I was surprised he was very open about it. I told him I had accidently seen him in the shower.

He proudly admitted that he had been doing it for several months. I was really stunned when he told me that he had started to do it with his grandpa. He had spent time this summer at the grandparent's place in the country.

He told me that his Grandpa had a really big cock and the two of them would look at porn mags and masturbate. Even crazier, he told me that his Grandma had told him that his penis was gonna be big too, since that kind of thing ran in the family. He told me that Grandma had measured their penises and watched them orgasm together.
