My elder stepsister who is crazy about cocks tells me to fuck her

He said you tell me yourself what would happen after the matchstick and petrol burn, similarly whether it is stepbrother and stepsister or anyone else, what would happen when a young boy and girl go under a blanket. I turned towards him and started looking into his eyes and soon we both came close to each other's lips. He started sucking my lips and I also started sucking his lips and gradually we both came in each other's arms. He immediately took off my clothes and I also took off his clothes and started kissing his body. I caught hold of his penis and then started sucking it, taking the thick penis in my hand, my whole body caught fire, every hair of my body was shivering, I was stretching.
