You wake up to me on top of you, I tell you I'm bored and horny and well.. you seem to be getting hard with me on top. I know we shouldn't be doing this because I'm your sister but you know it's going to feel so good. You're hesitant, I pull your dick out and start stroking it and sucking it. I rub it on my pussy and tell you how good it will feel inside me as I slide it in. Doesn't it feel so good to have your sister riding you? Maybe a little too good because you cum quickly inside me. You pull out and I show you how deep you came in me, you're still hard! I want to go again. What do you say? You take too long making up your mind I grab your dick and put it back inside me. I start riding you and you start to get up and take control, you get me down on my back and fuck me in missionary, slowly at first but I tell you to go faster and wow I didn't know how good you were at sex! You go deeper and harder til we both cum and then you zzzzz. You wake up with me stroking your erection telling you I want to fuck again. We both want it pretty bad, we're both exhausted already but I need your cum just one more time. I grind with you deep in me and we kiss and I ride you faster until you cum hard in your sis filling me up (creampie ending). Don't worry I'm not going to tell anyone!
