It is pretty obvious why Marina is one of the girls that PD considers his favorites. Her body is flexible and holds the marks from canes, rope and whips. Pain makes her pussy wet and she loves to have her holes filled by anything PD wants to put inside of them. Marina can hold the ridiculously demanding positions that PD dreams up and can even take the punishing pain and humiliation that comes with them. She is actually so into her own degradation that when given the opportunity to push things further she always asks for more. She may be the perfect, willing slave. She says it best herself. Her fantasy is to be the vessel for the fucked up sexual perversions of others.
