He fucks her without realizing it
my step-brother is always the angel of the house, even if in reality it is not true. My parents always believe, even if I’m innocent. Yesterday made me think that she had a cramp and I have massaged, but it was all a lie, he made me touch his cock for the case. Of course, my parents scolded me. Then, I sent him a message, and I did believe that I was his girlfriend. I waited in his room with his face covered and he fucked me thinking I was his girl. When he found out, was horrified, she was being fucked, the half-sister without realizing it. It was a vengeance which I enjoyed very much.
