I love my son's penis update

I caught my son masturbating and convinced him to fuck me with his beautiful large cock. Since then he has grown more confidence and regularly asks me for sex. But I was surprised to find out, he has started fucking our neighbor Susan 49 and has even fucked her ass. I saw him coming home last Sunday afternoon from her place. Susan is a born again Christian pain in the ass, but it seems she likes cocks a lot as well.
