The girl my friend knows that turns me on

The other day I was alone with the girl, she has come to find my friend in the house, but he was not there. He decided to stay and wait for him. But while he waited, he began to wonder what they said of you the other men, and touched the boobs. She is very sensual, and my dick is became hard when I saw the touch, clearly realized. She likes to excite men, and then was excited. He asked me to disrobe and I played with her. When I was naked, asked me to take a saw. While I masturbate, she touched her pussy and told me dirty things. The things that I could do, because she was the girl of my friend. And so on until I ejaculated in front of her.
