He fucks the two sisters in secret

I fucked my step brother for weeks, he has a dick very big and we like it a lot. Today I was making him a blowjob, but my sister has discovered. At the beginning I didn’t know why he was so angry, but then he told me that he had fucked for months. Our stepbrother scopava all, and two, and he had said nothing. Then my sister and I, we started discussing who would stay with him. Clearly I made the blowjob better, but my sister said that was her. Then, we have done it to three, so that our half-brother decides who scopava better. I was going to do anything to have the cock of my step brother.
