As you're walking past your sister's bedroom one night you can hear moaning and sounds of pleasure coming from inside. The door is half open, so you can easily see inside. You know that it is wrong to spy on your sister like this, but you can't help yourself. And what you see shocks you. Your sister is on her bed jerking her cock! Yes! Her cock! You can hardly even believe what you are seeing. You stand there, mouth agape, until your sister turns her head and notices you standing in the door frame. She cries out and covers herself up before demanding that you come into the room to talk to her. OMG! How... how much did you see?! I can't believe you caught me doing... what I was doing. I am so embarrassed right now, omg. Well, at least now you finally know my secret. Your sister has a girlcock. You probably think that I am a total weirdo... Wait.. you think that it is hot?! You really think that your sister's girlcock is sexy? Well, I definitely wasn't expecting that. I'm happy that you like it, though. Because.. well... the thought, the fantasy, that I was jerking off to.. was you. I've just, I've always thought you were so hot and sometimes when I think about you my dick gets so hard and I can't help but jerk off right then and there. Since you think that my girlcock is hot maybe you want to see it up close. And maybe you can help me out with this raging hard on. My dick is absolutely throbbing right now. Omg... it is so hot seeing my brother down on his knees in front of me like this while I jerk my cock. I never thought in a million years I'd be in this situation. This is sexier than any fantasy I could've ever dreamed up. You want this girlcock, don't you? Tell me just how much you want your sister's dick. Have you ever even sucked cock before? No? Well, I'm going to tell you exactly how to do it. Wrap your lips around the head and just do exactly what I say. Mmmm, you're so good at this. You're going to make me cum. And I know you want my huge, salty load. Where should I cum? Your sexy face? In your hot warm mouth? Or how about in your tight asshole? If you've never sucked dick before I'm sure you've never been penetrated before either. I want to be the first. I want to be the first one inside of my brother's tight virgin asshole. Let me warm you up by fingering you first. I'm going to stretch you out a bit so my thick cock will fit. You're so tight, I know your asshole is going to absolutely devour my cock and suck it right in. Mmmmm, this feels so amazing. Going in and out of you like this. You're so tight it's like a vice grip. I'm going to cum. I'm going to shoot my huge load up your ass and fill it up to the brim with hot, creamy jizz. ...That felt absolutely amazing. But, you still need to cum. Turn around and suck my cock again. You see how hard you still have me even after shooting out that huge load? Only you do that to me. Only you can make your sister's cock this rock hard. I'm going to cum again, and I want us to both cum at the same time. And when we're done, I'm going to have you lick up all my hot, sweet and salty cum.
