For a mature lady, the very fact that she is given in her mouth and cum in the same place is like a balm to her body. She feels that she hasn't lost her attractiveness and competes with her younger girlfriends on an equal footing. And the attention of the males tickles her vagina so much.
The son tried for four years in college to fuck his mother. You don't make promises, you make them! And the father didn't seem to mind too much to encourage his son to get an education. It was time for my son to get to know the pleasures of the family better. )))
