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.
Of course, the majorette doesn't know how to please her pussy anymore - she's had this and she's had that. Now she's getting to the driver. Only she doesn't feel anything for him, so she uses him as a free phallus. But he fucked her asshole hard to get even for the part she intended for him. Let her mouth serve as an asshole to go down in!
