I fuck my maternal and paternal grand-mothers. I don't know how my divorced mother would react if she found out. She thinks that hers is the only pussy I cum off in. She introduced me to sex when I was just 10 years old. At that age, my cock was quite thin, but she often brought herself off riding it. She also taught me oral sex. I wanted her cunt so much, and used to have sex with her several times a night.
