Mistress Gaia and her friend wanted to hire the services of this guy. But they knew where they were sending him was not an easy place and he had to be focused to come back successful. So they tested his focusing skills by stripping him and having one mistress make him lick her boots and the other one rub his dick with her heels. He was supposed to concentrate on the dick rubbing until he came while at the same time licking the other boots.
