I was in a confirmed relationship with my girlfriend of seven years. Her brother Max came to visit. We had lunch and I was doing the dishes, he came up behind me and grabbed me and put his hand in my pants. He got his finger on my clit and rubbed me while he humped my backside. I got aroused and pushed my pants down and took it from behind while leaning on the sink. He was going hard on me when I looked out the kitchen window to see our neighbor's three year old staring at me. I kept eye contact with her until he finished and pulled out.

My girlfriend was standing in the back of the kitchen with a face of total objection.

I used the kitchen towel to wipe ourselves, and could only give my girlfriend a big kiss. His nickname is Mad Dog, and he surely made me his bitch that afternoon.
