Evil man likes to train couples in sex.

His reputation as a tough and evil man was just a facade but what he truly loves, being a guide for all those who came to him seeking teaching for their bodies. For he was an expert in sex, not a doctor, not a therapist, just a man who knew how to handle bodies to give them the most extreme pleasure.  His specialty was couples, both newlyweds and those who had been together for years and for whom pleasure seemed to have been begged for, but he managed to get them to connect again, with his personal guidance, with his ever-present notes on the sidelines.
