He is completely straight and she is completely bi. He is sweet with her being bi and in that context the relationship is open....as in she can have relationships with women on her own terms and in her own time with no expectations to either bring her home or tell him anything about it. But, sometimes they do enjoy having a threesome here and there and maybe one day he is open to a few extra things i.e. like adult parties. In their own sex lives he is the dominate and she loves being tied up and spanked and overall she is the one with the higher sex drive. Often she has to travel to Christchurch and would be keen for a 'girlfriend' to catch up with from time to time...Oh and she doesn't mind him having a play with a women in certain circumstances...but being the controlling bitch she is would much rather that she is watching ;)
