I can't believe you came in my room tonight asking for a blowjob! Why would I do that to you, I'm your sister! Don't you have a friend that's a girl that you can ask. I know you need to practice especially because you're still a virgin but why would I want to do that for you? Ok ok, stop begging. If you want me to do you this favor you're going to have to do me a favor. I want all of your Christmas money, I know you got a lot and I want it. Wow you actually have a big dick, I really enjoy gagging on it brother. You want to do more? I'm going to need more, how about all of your the money you're going to get for your birthday.. Perfect. Oh my brother your dick feels so good to bounce up and down on. Oh my god I want you to cum deep inside of my pussy, you're not so bad after all..
