Secret sex affair with my friend's husband!

I was with my friend again and wanted to spend the evening with her. But this time her boyfriend was there, too. He's kind of hot and she really mustn't find out that we've had a few times together. But this was really risky this time. She wanted to do something else, take out the trash or something, at least she's just out the door. And he was in the bathroom. In the bathroom, where I often gave it to me :-p I wanted to take the chance and went straight to him and knelt in front of him. At first he didn't really know whether to get involved, but no sooner did I have his cock in my mouth than his conscience was blown away. We have done it secretly together and to top it off he injected me fully. His sperm ran later when I was sitting next to her on the couch still in my panties - oops!
