Red has three newcomers in her sex addiction clinic. Louise and Rio are diagnosed nymphomaniacs and Christian is a chronic masturbator. But, as she gets them to discuss their problems, the girls take a liking to Christian. Before Red knows what is happening they are stripping him off, ignoring her shouts of "control yourselves"! When he is naked the girls help themselves, wanking and sucking his huge dick as Red looks on horrified. Rio then decides it is too good to resist and forces him to fuck her in several positions, screaming her head off as she rides the big dick. Louise kisses Rio as she rides the naked guy and he soon explodes all over their faces to the disgust of counsellor Red!
