A mature man conducted an excellent sex therapy session with young brunettes

A pair of cute young sisters have a pressing problem – they masturbate with anything they can find. That’s why a psychologist comes to them in the form of a man who talks to the girls and then watches as they masturbate with hairbrush handles. Eventually, he convinces the girls that it is more natural to have sex with each other with his help. In the end, he gives the girls a big cock to suck. And through group sex, he teaches the girls about normal human sex.
