“I have to go to school,” I say to my dad as I’m getting dressed.

“Courtney, don’t you want to talk about this?” He asks with a look of pity on his face. No, I will not be pitied in this situation.

“Absolutely not,” I say, “I’ll see you at home.” I leave my dad’s office building with sex hair, and what feels like a broken heart. My school is a mile away, but I figure walking there will give me time to think. My dad not only just fucked me in his office, but then told me that he took my sister’s virginity. I feel like I might throw up. Does she know about me and him? Did she do this out of spite? I can’t decide if I’m sad, angry or just straight up jealous. I thought I had them both to myself, and now I come to find out they’re doing it behind my back. Did it happen more than once? Too many questions, not enough answers. But I know where I’ll find my answers.

I get to school, knowing full well I’ll get a detention for being late, and head to my second period math class. I just so happen to have that class with my lying, slut sister, Cassie. When I walk in she glances at the door, and if she’s not an idiot, knows that something’s wrong with me. I sit down across the room and try to pay attention to the lesson, but my head is spinning.

“What’s going on?” Cassie asks me, two seconds after the bell rings.

“How many times?” I ask her, “How many times have you and dad fucked?”

“Courtney! Shhh! We’re at school for Christ’s sake!” She ushers me out of the classroom and towards the closest girl’s room. “How did you find out?” She asks as we get into a stall.

“He just told me. After he fucked me on his desk and came inside me,” I say, trying to at least keep my pride by letting her know he still wants me too.

“He… he just told you?” She looks astonished.

“Yes, he told me. Not you. Cassie, you’re my best friend, my sister, how could you hide something like this from me?!” I’m frantic now, feeling nothing but betrayal.

“Oh, like I’m the only one keeping secrets!” She’s very angry. “I saw you and him fucking a few weeks ago, and it didn’t look like your guy’s first rodeo.”

I know I should be mad, and part of me is very angry, but this girl is my best friend, my life line. I can’t just be a heartless bitch towards her, especially when I’m just as guilty as she is. The truth is that we both deserve an apology from the other, and I decide to be the bigger person, even if she is three minutes older than me and therefore should apologize first.

“Look, Cassie,” I say, “I’m sorry. It first happened on our birthday. That’s how I got him to stay quiet about finding us naked together. When I went to go talk to him he was naked in his room, jerking it. After that I didn’t want to tell you because… well I don’t know exactly.” I sigh, this is harder to explain than I thought, “The point is, I should have told you sooner. I’m sorry I hid this from you.”

Her face softens, and I can tell she’s not mad anymore. “I forgive you. And I’m sorry I didn’t tell you, too. I mean, I didn’t know how to. I walked in on you and daddy fucking right there in your bedroom. It was really hot, to be honest,” She says, with a smirk on her face.

“You’re impossibly horny, girl,” I say to her as I pull her in for a hug. The bell rings for third period and we just look at each other. “Skip?” I ask.

“Skip,” She says, “Where shall we go?”

“Anywhere that I can get those clothes off you,” I tell her with a wink.

We take her car home, since I walked to school. On the way there I think about how happy I am that we made up, and how relieved I am to be hiding nothing from her anymore. Am I still jealous that daddy isn’t all mine anymore? Yes. But sharing him with Cassie doesn’t sound half bad, especially if I can have them both at the same time.

Cassie parks her car in the driveway, and before I can even reach the door handle she’s unbuckled her seat belt and is leaning over the center console.

I’m about to ask her what she’s doing, but her mouth is on mine before I can say a word. I bite her bottom lip, hard, and she pulls away.

“You skank,” She growls as she touches her now injured lip, “You’re gonna pay for that.” She leans over and bites my neck, and I moan. “Sissy likes to be bitten, doesn’t she?” she whispers in my ear before biting me again. Then she’s kissing my collarbone, the tops of my boobs, “Take this off,” She commands, tugging at my shirt. I do, and then she’s unhooking my bra.

“Wait,” I gasp, “Shouldn’t we go inside?” Not that I don’t love some good car action, but these are very awkward angles and I need her spread eagled on a bed. She doesn’t answer me, just opens her car door and runs into the house. I pull my shirt back on and follow. “Where are you?” I yell once I’m inside. She comes out of nowhere and pins me against the front door. Her mouth is on my neck, her hands tugging my shirt off again. Then she’s licking and pinching my nipples, and it’s all I can do not to scream. “Mmm fuck yeah, suck on my tits, big sister,” I moan. She’s grinding against me now and I’m squeezing her ass. I grab her hair, pull her away from me and say as demanding as possible, “Bed. Now.”

When we get to her bedroom she closes the door, and immediately starts taking off her clothes. I help, tugging her jeans down and practically ripping off her panties. I throw her onto the bed and start to kiss her body all over, focusing mainly on her nipples and inner thighs.

“Stop teasing me, Courtney,” She says between moans. She wants it so bad, I can tell.

“Tell me what you want, sis,” I say to her with a devil smile.

“Touch me, kiss me,” She gasps, “Lick my clit, put your fingers inside me, anything!” She’s panting now. I decide to give in. I slide my index finger between her lips to find that she is dripping wet, and then I just have to taste her. I dive in fast, running my tongue from her hole to her clit, God she’s so sweet. I flick my tongue over her clit and hear her moan my name. I continue to lick her all over, and stick two fingers inside of her and she’s moaning, “Oh fuck yes, fucking finger fuck me, you slut. Make your sister’s pussy feel good. Ohhh my God.” Knowing that I’m making her feel so good makes me want to cum right there. I reach up and pinch a nipple between my fingers while still sucking on her clit, and I feel her pussy tighten around my other fingers. All she can manage is, “I’m cumming!” as her orgasm rips through her.

“Did you like that, sissy?” I ask sweetly, assuming she’s ready to cuddle and go to sleep.

“Take those off, slut,” She says, pointing to my pants. I do as she says, surprised she’s ready for round two already. Maybe losing her virginity had more of an effect on her than I originally thought. She pulls my soaking wet undies off and looks at them. “Daddy’s cum…” She murmurs before she licks them. For some reason this gross, dirty act sends a shiver down south and I reach down to touch myself. Before I can get there, however, Cassie swats my hand away and puts her mouth on my pussy.

She runs her tongue up and down my slit, agonizingly slowly, and sticks her tongue into my hole. “Mmm you’re just full of daddy’s cum, aren’t you?” She asks before lapping at my juices more. I am in a complete pleasure fog, barely aware of anything other than how good I feel. She’s sucking my clit, squeezing my boobs, flipping me over so my ass is in the air, grabbing her vibrator and sticking it in me. She thrusts it in and out, fast. I feel good, so fucking good.

“Fuuuck yes, Cassie. Fuck meee. Mmm that feels so fucking good. Lick my clit, fuck my pussy. Mmm,” I moan.
“You like that? You like your twin sister fucking your pussy?” She prompts, as she slaps my ass, “You’re a dirty little girl, Courtney, you need to be spanked.”

“I think you both need to be spanked,” Says a deep, male voice from the doorway. Cassie stops what she’s doing immediately, and I open my pleasure heavy eyes to find my dad, naked, stroking his cock in Cassie’s doorway. “This sure is some déjà vu, girls, but this time I think things will pan out a little differently,” he states as he starts walking towards us with hunger in his eyes.
