Want To Try Lesbian Sex

I am straight and I have a boyfriend. I have never had any sexual encounter with a girl.
I live with my female roommate. I keep having dirty thoughts about her. I am watching dominatrix porn for hours and dreaming about her. She is really strong and badass. I am more of a submissive type. I want her to dominate me so badly.
I want her to pull me over her lap and tear off my panties. I want her to spank my ass so badly. I want her to spank me as much as she wants. I will obediently strip in front her and lick her pussy. I want her fingers inside me, I want her to beg me to cum. I want her to make me walk naked around the house. I would be so nervous and embarrassed but I want it. I want to do anything she asks. I would visit her friends and they can share me. They can stick vibrators in me, fuck me with a strap-on, sit on my face.
