Ha, ha - took a guy off on the beach promising to show her stretching at home. Such a tight ass no one would miss! And she, too, when she saw the size of his corkscrew, was already thinking of nothing but that - so excited for him to uncork it! I am sure she has already measured it with her eye. Now she will brag to her girlfriends that she fucked a 23 cm stallion!
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.
I want to fuck a pretty girl like that, too.
