[M4F] My flatmate's girlfriend makes me an offer - I can do whatever I want with her for a night if I suck her boyfriend's cock.

Let me go back to the beginning. I've always had a crush on her. I was crushed when she started dating him, but soon perked up - it meant I got to see her a lot, and she'd started to wear less and less around our flat. I even came back from class one day to her naked blowing him in the middle of our living room. It was almost like she wanted me to see.

Well, one day she came to my room in a tiny piece of nightwear. She slunk over to me, climbed onto my bed and whispered to me before I could react.

"Suck him off," she purred, "And you can have anything you want!"

At that moment my flatmate stepped into my room. He was naked, his cock was hard, juicy, and far bigger than mine. I felt her kicking me out of my bed, on to my knees. Before I could help myself his hand was on the back of my head and my lips were parting.

[Do I actually get to fuck her, or will she keep making me do more stuff? Your call!]
