Look at what a good relationship this guy has with his father’s wife, so that they end up in bed fucking like Cossacks. And he thinks that the old man has his wife very neglected; that despite being in her seventies, she is a horny slut who needs much more sex than she receives. And the proof was when he came home and caught the busty old woman fingering herself alone on the couch. It was clear that she needed a fuck very urgently, and he couldn’t let the lady suffer the frustration of not feeling a good xxx cock in her old pussy.
