I have often seen my s***r naked when I was with my m***r. Either in the shower or he was sitting naked on the terrace. I always noticed his huge cock, which I would love to suck. When I recently brought the groceries (m*m was not there), he was lying in bed dreaming. That was my chance. I went to him and just started blowing his hot spanking. After he was scared for a moment, he started straight away. He licked my pussy, fucked me violently with a free lance and gave me an insane orgasm. Now I know why my mother thinks the old sack is so cool. Next time I want to feel his cock in the ass.
