Mugur is one of Frank's guests of honor. One of the things Frank really wanted to try on Vivien was the hot wax treatment, but he let Mugur do it because he is a great friend and is a bit of a pyro. Luckily they are in the basement because the screams get pretty loud and when Vivien gets tied and when she sees the flames getting close to her face she gets pretty nervous. Of course that is how Mugur likes them - he gets such a rush from seeing the anxiety build and he can't wait to release it with a hard ass fuck!
