I lay there underneath and masturbated while watching as my step brother fucked her. Alanna stood up and ran over to get her cloths “ sit the fuck down and don’t dare put any cloths on “ I ordered her. Alanna agreed and told me to go first, I choose truth, she smiled and said to me “ have you ever thought about fucking another girl” I leaned over and whispered in her ear “ the only girl iv ever wanted to fuck is you” she smiled and told me it was her go and she was choosing dare, I said “ for your dare you have to be my slave and do whatever I say” she hesitated for a minute then agreed.
