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.
It seems the brunette herself realized that a satisfied trainer is a good trainer. It didn't take long for her to get all conventional... The pussy-licking trainer was quickly found, too. So the trainer didn't even have to unbutton his pants - the girl handled it herself. I love this kind of advanced student sports. )
