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.
Nice way the grandpas got their dicks in her pussy. She may not have counted on such a vigor, but the fellows were old school - pawed at her like young horses. And the honorable thing was that they didn't forget her ass. That's who wouldn't ruin a furrow. They got positive emotions from the girl and went to play dominoes. With that kind of energy, you could be playing with chicks till you're 100 years old. One stick adds a year to life!
