Without Limits (2001)

Andrew is a rich business manager, a reserved person who loves sports and tries not to let Michael, a friend and business associate, get him involved in group sex situations. Nevertheless, behind his formal outward appearance, Andrew conceals a rather perverse personality. In fact, when he is alone, he organizes little parties at which he enjoys sex with various prostitutes...An extremely hot thriller with exciting sex scenes, anal penetrations, DPs... and carrying Antonio Adamo's unmistakable seal of quality.
