you watch me change into my pjs as we get ready for bed. sharing a bed with your little sister makes you a little nervous but a little excited too. we joke about how this sounds like the set up to one of those pornos. as we crawl into bed, I ask if you think those actors are ever really related. probably not, right? anyway, goodnight! I close my eyes and drift off... but I wake up in the middle of the night to find you jerking off right next to me! I pretend like I don't see you but I watch you for a while, smiling to myself. I start inching my butt closer to you to see how you react. still pretending like I didn't see. you rub your cock against my panties and I let out of a soft gasp. I slowly wind my hips, rubbing you against me until you pull my panties to the side. this time I really gasp and you know I'm awake now. you slide your cock between my thighs and rub it against my wet pussy for a while until you can't resist the urge any longer and you slide it right inside me. I whisper to myself "oh my god, I can't believe he stuck it in! but it feels so good" - we spoon fuck very sweetly for a while, I moan so softly as to not wake anyone else up. I get on all fours and wiggle my ass at you before sliding my panties off my hips and thrusting myself onto your cock. I work my hips on you until you start fucking me harder (fuck machine) and eventually I flip onto my back. I close my eyes and cover my mouth and I have multiple back to back orgasms and when I open my eyes, I see that you gave me a creampie!! I whisper "I can't believe he didn't pull out" by my smile tells you I'm glad you didn't...
