The last time I ran away from home and when I returned, my sister gave me the light to my father. I was on punishment for a week. And now that I surprised my sister who was returning home in the early hours of the morning, it was my moment of revenge. And I have to say that I have done something very dirty, I blackmailed. But no matter, she was already a whore without the need of threats. I said that he had to fuck me. Clearly, he accepted. I touched her enormous natural tits. I forced her to make me a blowjob. This happened in the living room, but I wanted to have more sex, so we went in the room. There, she has ridden my cock, and I fucked in her doggy style. My half-sister was a real expert of cock and pleasure.
