Only eyes of the brunette give away her age - one can feel much experience, and the body is young, even with her standing chest you wouldn't say that she may have such an adult son. It was all the more interesting to watch his seduced mother. The movements, the hints with her body - in this she would give a head start to anyone who was years younger. And even more so in the sex itself, she was a match for anyone else. Smart, hot, hot. In a word - mature.
Well, I don't think this mature madam is the grandson of this overgrown man. And from the way he talks, he apologizes to her first, not as his grandmother. The age of this lady is certainly not young, but her pussy and tits are quite well preserved and still quite firm in appearance.
