Girlfriends 18 year old sister

The excitement died down and I thought it was over. I was wrong. They laid me on my back and began to suck my cock. Usually I can not take this much in one day but I was so turned on that I still wanted more. They took turns sucking my dick and kissing each other. I looked up and noticed that they were also fingering each other. One would suck my balls as the other would move up and down my cock. I felt their long blonde hair on my body as they took my dick in their mouth. Then I just could not take anymore so I squeezed the bed and came with a mind blowing orgasm. Susan and Jaime shared the cum and it oozed down their faces and tits.
We then got dressed and went back to watching T.V. Their mother came home and asked what we had done all day. “Nothing much” we said in unison and the girls sneaked a sexy smile in my direction.
