Hey step-brother. You are 18 now. A big boy. I know that you have been fantasising abot me. So this will be my birthday present for you. You can have me. I want to suck you off and ride you step-bro. mmm that feels so good. I have been dreamign about it, too. Cum inside of me I want to feel your seed inside of me. that was so great. btw I forgot to mention that I am ovulating now and I don't take pills so you will probably be a step-father step-bro
