Practice on a slut

A young dominant stud with his boyfriend who's a Master, is cruising in a sex-club. The couple is used to fucking subs together but the young top still needs some training to become an expert top for subs. Around a corner they come across a tied up hairy dude, ready to use. They set him free so that he can start using his hands and mouth on their cocks. After a bit of horny ass-licking action the sub gets spit-roasted with the young top fucking his ass while the older Master shoves his dick down his throat. The young leaner is doing well, giving a great pounding...at the end, the master takes his place and shows him how it's done!
