Pretty soon she started shaking and increased the pressure on my cock. I told her I was about to cum. She did not let up or stop. I started to cum and she did something I did not expect. She put her mouth over my head and took it in her mouth. After we were done she looked at me, smiled and swallowed my cum.

I asked dawn "don't you care if I have sex with your sister"? And she said "I don't care do what ever you want" then Dawn went down to share my cock with her sister who were taking turns sucking me off.

I gave.
