I walk in to my room to find my step-brother laying on my bed, he tells me that he has seen all my naughty videos. Which i denied to him. He then shows me, my naughty pictures of me from videos i have done, which i then ask why does he have them on his phone. He then says he wants me to be naughty with him, exactly like i am on my videos, which i said no it would be totally wrong as he is my step-brother. He then blackmails me in to doing it, else if i don't he will tell mum and step-dad everything
