do(m)inated in bisexual threesome

My old friend/roommate had a really hot older sister who was always hanging out at our place. She was a really sexy, fun girl who was really into going to raves/edm concerts and would sometimes invite us with. Her and I were constantly flirting with each other (well I would always flirt with her) but she always had a boyfriend so that's where it usually ended.

But at some point she and her boyfriend came home late to hang out after a night out but it was just me at home. They joined me in the living room watching a movie and eventually started making out. At one point they apologized to me and I jokingly said something like "hey, don't mind me". My roommates sister said "oh yea? maybe he can join in?", i thought she was joking but her boyfriend took her shirt off and she just looked at me with this sexy look that immediately made clear she was not joking around.

At that point I had probably jerked off to her a half dozen times and so I got up without hesitating and went to grab her tits without even thinking twice, but she pulled my hands off in a teasing way and said "not yet"… still holding one of my hands she moved it down to her boyfriend's crotch and I felt a giant hard on. I looked at him and he was just smiling like they had done it before, I instinctively pulled back but she held onto my hand and asked if I wanted to fuck her. I of course did and I went put my hand back on her boobs but she moved them back to his cock and told me I needed to do something else first. From there I basically just said fuck it and went with it, I ended up jerking him off, she started making out with me while I was doing it and guided my mouth to his cock. It was shocking at first but I found it really hot and she made me deep throat him until he came in my mouth. He had a huge dick and she kept saying things like "you like that?" as she would push my head further on it.

I didn't even get to fuck her until we did something similar a few weeks later and I every time I would see her before then she would tease me and tell me that we could hang out if i was a "good cocksucker for her again", she would even hint at it in front of her brother/my roommate and pretend like she was going to tell him if I didn't do what she said. ever since then I have found the whole domination thing really hot…
