Her Best Friend Becomes Her Sir (F for M)

[Usani]

I think it would a fun story between 2 best friends who have known each other since childhood and one night both decide to walk on the wild side.  They both go to the club where everyone where's masks to hide their identities so basically whatever goes goes.  The thing is they don't know who the other person is since they both went separately. 

The first night they are instantly drawn to one another and they spend time together every night at the club for almost a month.  After a month they decide to unveil their faces and that's when things get more interesting.  By this point they have already had sex, he's dominated her from the first night.  So what happens when she finds out her Dom is her best friend?
