I hear my twin sister, Cassie, open my bedroom door and run giddily over to my bed. Itâs Wednesday, which means that our dad will be out of the house all day, unlike every other day when he works from home. It also happens to be our 18 th birthday, so he let us stay home from school today. Clearly Cassie is excited to have the house all to ourselves because when I peak an eye open and look at the clock, I see that it says 6:15. I do a mental sigh and squeeze my eyes shut.
âCourtney, wake up! Dad just left!â Cassie jumps onto my bed and straddles me. âHappy birthday sissy. Nobodyâs home⌠just usâŚâ I know what she wants, but quite frankly, Iâm too tired. I try to push her off of me so I can go back to sleep, but she is not having any of that.
âItâs 6 in the morning. Iâm tired. We have all day! Let me sleep in.â I mumble with a yawn.
âThat is exactly why,â Cassie says while taking my blankets off of me, âWe should get started early.â Now that she has all my blankets off me and Iâm freezing, I open my eyes. The girl I see on top of me has the same green eyes as me, the same heart shaped face, the same nose, the same thick wavy hair, although hers is our natural blonde color, I dyed mine brunette. And so, despite my crankiness from being awake at this hour, I smile. âThatâs more like it! I love to see those pearly whites so early in the morning. Now are you ready for your birthday present?â Still on top of me, she takes off her night gown to reveal her perky 36D tits, which even though theyâre just like mine, I love to see.
âOh, I like where this is goingâŚâ I say, starting to get worked up. Me and Cassie have been fooling around for years, in secret of course. I canât imagine what would happen if our dad found out. Weâd probably be out on the streets before I could say âdaddy why donât you join us?â
âMe too, little sis.â Cassie is always calling me the little sister, even though sheâs only 3 minutes older than me. âNow letâs see what you have on under hereâŚâ Sheâs in between my legs, sliding my shorts off. âAhh, lacy panties? Mmm Cassie likes.â She licks her lips and slides my panties off. She runs her index finger over my already wet slit. âWell somebody must have been having a good dream. You must tell me about it later. But for nowâŚâ At that she runs her tongue in between my lips, and laps up some of my sweet nectar. âYou taste so good, baby.â She says, before diving in to start her attack on my clit.
âMmmmm, yessss. Lick my clit you dirty slut.â I moan while grabbing the sheets so hard my knuckles turn white. Her mouth is everywhere, licking my clit, sucking my lips, diving in and out of my tight, virgin hole. âYessss, big sister. Fuck my hole with your tongue. Mmmmm.â I am in complete bliss. She starts sucking my clit while fingering me with two fingers, rubbing my G spot every time she thrusts them in. I am moaning uncontrollably, writhing under her mouth attack, I feel it in my belly, and as I find my release I yell âIâm cumming! Donât stop baby, donât stop. Yes, yes, yessssss!â I explode, my toes curl under, I bite my lip, and I ride out the waves of my delicious orgasm brought on by my very own sister.
When I open my eyes, Cassie is still on top of me, with a huge smile on her face. âHappy birthday baby sis.â She says. Before I can say it back, however, her mouth is on mine. I can taste myself on her tongue. Despite my mind blowing orgasm moments before, I am ready to go and extremely turned on by this. I grab her bottom lip between my teeth and she moans, she loves biting. I flip her over so that Iâm on top. While my tongue explores her mouth, my hand travels to her left boob, and I pinch her nipple. I hear her take a huge intake of breath. My other hand travels south. Down her stomach, across her cleanly shaven mound, and to her opening. I am pleased to feel that she, like me, is soaking wet down there.
I insert one, then two fingers, and rub her clit with my thumb. She moans into my mouth and chomps down on my bottom lip. I break the kiss, and start sucking her neck. She pushes my head down, however, so I donât give her a hickey sheâll have to explain to our dad. I start sucking her nipples and sheâs thrusting her pelvis to meet my hand.
âOhhhh baby sis,â She moans out, âyesss suck my nipples. Ohhhh ahhhhh fuck yessss!â
I can tell sheâs about to cum. I know her body well. She grabs onto my shoulders, I can feel her nails digging into my skin, and just as she yells âIâm cumming!â I hear another voice. A man voice. Coming from my bedroom door. But this one says,
âWHAT THE FUCK IS GOING ON IN HERE?â Itâs my dad. I try to find the blankets to cover us up, but theyâre on the floor. I realize itâs too late for Cassie, you canât reverse an orgasm, and her eyes snap open and lock with my fatherâs, and they maintain that eye contact while she finishes.
