Cocky Step-Son

Phil's cocky but very hot stepson comes to stay. He is a mischievous pervert and when he finds Stephen alone in a thong and pullup stockings he challenges his suitability as the husband. What he is really after is a good hard fuck and wastes little time proving what a willing ass he has. The two fuck hard thinking they have the house to themselves but then Phil returns and catches them fucking. What could possibly be the outcome?
