The first time I fucked my sister in the ass on the chair until my parents were at home

When the guy came home to his sister, there were no parents, but she was alone and was very happy to see. The girl asked to fuck her in the ass, because there was no sex for a long time, but I wanted to try something new. He agreed and licking her ass put his thick member right inside, after which he put her on a chair and fucked it well to orgasm.
