Good foreplay. He got her very wet so that when she sat on his cock it slipped in so easily. That got this old fella very aroused. Hope the wife gets back home very soon.
I love that great connection you two have after all these years and miss it in my own life. It's fun watching you two fuck and seeing that you enjoy those little subtle movements and that sweet pussy with those big balls still hanging low. You two are truly a fantastic example to the young people watching these videos. Amen to Jim Webley's comment.
Xxx.
