The scene starts with me (the sister) and my friend talking in my living room. We are both talking about a guy we like, and then she brings my brother up. She says that she heard from one of the girls he hooked up with that he have a really nice cock and he is a good fuck. I am grossed out and tell her to stop talking about it. But, secretly, I am kind of turned on. Cut to later that night. My friend has convinced me to sneak into his room while he’s napping to try to see his cock. We both sneak in and pull his covers off. I try to look un-amused and grossed out, but I am actually turned on. My friend then dares me to touch it. I object, and tell her she is gross for suggesting that, that I am his sister. She says fine, she will. She starts stroking his cock while he’s still napping. I tell her to stop in an unconvincing way, that she will wake me up, but she doesn't stop. The more she strokes his cock, the more turned on I am getting. I notice that my friend has started playing with herself with her other hand, and I start to do the same, but trying to hide it from my friend. After a couple minutes, she then dares me to suck his dick. Again, I tell her that she is gross, and that we both need to leave, as he could wake up. She then tells me that if I won't suck it, she will. I still protest, so she then starts sucking his dick. I am now just staring at my friend sucking his dick and without realizing it, I am aggressively playing with myself. My friend finally notices that I am playing with myself, and smiles at me. She teases me telling me how good he taste, and asking if I am sure I don't want a taste. It is at this point he wakes up, and we both freeze, my friend lips still wrapped around his cock. I start panicking and stammering, but my friend removes his cock from her mouth, jumps on him, and tells him to be quiet, and that we were just having fun. She said she had heard a rumor about his dick and how good he was in bed, and that she wanted to put that to the test. Before he can protest, she takes off her panties, slides his dick inside her and proceeds to ride him. I just watch silently, and continue to play with my pussy. After a while, I start to become jealous of my friend. I know I shouldn't, but seeing her ride him is making me so horny that it is driving me insane. Just before she starts to orgasm, I push her off him, pull my panties to the side, and take her place, lowering myself onto his hard cock. I moan loudly as I start riding his cock. My friend complains to me that it’s not fair and it was still her turn. She pouts and says she was so close to cumming and I just took over. I become very territorial and tell her that he is my brother, and that I get the first orgasm. I tell her to be a good little slut and play with herself while she enjoys the show. I also tell her that if she is lucky, she will get to cum eventually. After this exchange, I turn my attention back to him, and ride him with renewed vigor. After not much time, I start to cum on top of him. I convulse in pleasure from my first orgasm with my brother. I slowly get off of him, and tell my friend she can have a turn. My friend wastes no time, and hops back onto him, lowering herself onto his cock. As she rides him, I start play with myself again. Even though he is fucking my friend, all he can think about is fucking me. It is not long before my friend is nearing climax again. But he do not care, and throw her off of him and direct his lust towards me. He climb on top of me and start fucking me in the missionary position. My friend is complaining again, but we both ignore her, we are transfixed on each other. We fuck hard and passionately. I ask him repeatedly if he likes fucking his sister. I orgasm for the second time, this one more intense than the first, but we don't stop this time. He then flips me over and starts fucking me from behind. At this point, my friend has stopped complaining and is just enjoying the show. She is furiously rubbing her pussy while she watches me fuck my brother. I keep telling him to "fuck your sister's pussy". My friend then joins in and tells him to fuck his sister harder and faster. Then she asks me how I like fucking my brother. This sends me over the edge and I cum again, but this time, my friend cums with me. As my orgasm subsides, I realize he must be getting close to cumming. I remove his cock and my friend and I start begging for his cum. I tell him to cover his sister's big tits in his cum. My friend is stroking his cock while I continually ask for his load. He finally cum all over my big tits. After my friend and I played with his cum on my tits a little, we get up, and tell him to get some rest. Because she is spending the night again tomorrow, and this was just the start of the fun!
