Brazen stranger fuck in front of my flatmate

You know I love to fuck, no matter when and where! This time it was my flatmate Lisa's turn. I was so incredibly horny that I didn't really care whether she was still in the room or not, so I just shoved my boyfriend's hard cock in my mouth. And after the cock was nice and hard, I just had to sit on it! I think my flatmate looked pretty stupid :P
