My brother comes into my room just in time. I need his help to keep the ladder still while I fix how one of my plants is hanging on my wall. Even though I'm distracted, I know that my brother's face is really close to my ass. I don't mind it so much. I'm his sister, so it's not a big deal really. Then I hear him sniff. What the fuck is he sniffing? I know I heard it! I could practically feel his nose in my ass... What is that about? Now I see that he is hard! I can't believe this. This is so awkward. He's such a perv. How long has he been doing this? Was this an accident, or has he been doing this on purpose? I tell him to be honest, and he tells me he's had feelings for a while... wanting to be closer to me. I don't know how I feel about this. I know it's wrong. Now I'm thinking about every time I've worn a skirt and I've felt him looking. I just wrote it off because I'm his sister. I mean, I'm flattered that he finds me attractive, but it's just gotta be a sister thing, right? He tells me I'm pretty and that he thinks about my body. That's so weird... we used to bathe together! Yeah, we both have grown up, and I developed pretty fast. I didn't think he was looking though. He looks me up and down and says he likes it. Well, he did turn out pretty hot too. He says he's been wondering what's underneath. No, I don't want to show him. That's kinda wrong. It's nice that he thinks I'm hot, but I just assumed that he has a nice cock. I don't know if I want to see it... but yeah I kinda do. No, we should just stop and do something else. Yes, I've noticed how hard he is, and I'm trying really hard not to look. He does look pretty big. Despite myself, I can't help but take a couple peeks at the massive bulge in his pants. He insists that he wants to see what's underneath my clothes. I tell him it's wrong, but he gets assertive anyway. He grabs me and turns me around, pulling my pants down. I'd be lying if I said I wasn't turned on and enjoyed it. Fuck, I can't believe how turned on I am as my brother pulls my panties to the side and gets his face right up next to my ass and soaking wet pussy. I can't believe we are doing this, and I tell my brother that maybe we should stop. He's not convinced that I mean it. Fine, if he really wants to taste my pussy, I'm not going to stop him. He buries his face in me, licking my pussy with the rest of his face smashed in my ass. His tongue feels so good, and I can't believe we are doing this. He likes his sister's ass smashed into his face. I can't believe I am about to cum on my brother's face! He makes me cum so hard, and I want more. I start stripping for him, asking him to convince me that we should stop. I obviously don't really want to, as I pull off my pants and rub my titties in his face. I can't believe he has fantasized about this body, his own sister. It's time to return the favor. I get on my knees and put my brother's cock in my mouth. I can't believe how big it is. It barely fits in this tiny mouth. I get it nice and wet as I pull my titties out for him to see. My pussy is so wet I can feel it dripping down my legs. I can't take it anymore. I need to feel my brother inside of me. I climb on top of him and slide his huge cock inside of me. It stretches my tight little pussy so much. Who knew my brother had such a marvelous cock? It feels so good. I'm so wet that I pull his cock out and rub my panties all over my soaking pussy. I get them nice and wet and give them to my brother. I tell him those panties are his now to enjoy as I ride his cock. I talk dirty to him, now knowing how long he has been fantasizing about his sister... how long he has wanted to me me take this fat cock... I want to feel him cum at the same time as me. I want to make him feel good and cum for me, just as he made me cum with his mouth. I need him to cum for me. I can feel how full his balls are for me. I talk dirty to him, telling him to cum for his sister. I want that cum sprayed all over me. He pulls out at the last moment and shoots his cum straight up, getting it all over my titties and hands, soaking my pussy, and dripping back on him. Wow I can't believe I just had sex with my brother. Of course it was amazing. Just to be safe, we probably shouldn't do this again because we don't want any accidents. My brother gives me a sly smile and says, "We'll see..."
