I'm alone tonight. Well, alone from the people I want to be alone from. Primarily anti-drug parents who are away for the weekend at some marriage counseling. Although my sister is upstairs, she's a lot more open to drugs, especially chocolate. (Yes, chocolate is a drug to us. We're huskies, what did you expect?) Anyway, this means I can take part in my most favourite legal pass time.

I look up to my sister's bedroom, my ears twitching to make sure she's up there, before going to my backpack. I go into the small pocket within the main pouch of the bag, pulling out a bar of a mixture of both white and plain chocolate. My favourite type, the taste of white chocolate with the coco overtone of plain.

My tail wags as I open it up and cracking the first line, putting the line of squares into my maw and chewing it softly. I love the taste and moan as I gulp the mass down my throat. I move over to the couch and wait for it to take affect on me, cracking another half a line and letting it melt inside my snout.

After a few minutes I feel my mind space out slowly, my arm going over the edge of the chair. My ears perk up slightly as I hear my sister come out of her bedroom, going down the corridor before stopping halfway. I can almost hear her sniffing before she comes down the stairs, opening the living room door.

"You've got chocolate? Why'd you keep it for yourself?" She asks as she takes the bar from me, I'm only able to keep the half of line I already cracked off.

"Because you hog all of it," I reply begrudgingly.

"That's only because you're a lightweight, you buy just one bar of the good chocolate, while I buy five bars of the cheap stuff. Keeps me higher for longer."

"Oh just because I have a standard for my highs."

She scoffs mockingly as she takes two lines and eats it quickly, sitting next to me. "Suit yourself newbie."

"Hey, that's mine."

"I needed this today, I forgot to get my heat medication this week and it's too late for it to take affect."

"Wait? You're in heat?"

"Yeah, what about it?"

"N-nothing," I say, internally freaking out.

She's in heat!? Shit! Fuck... I'm always bloody horny when I'm high, and now my sister is a biological ticking time bomb. I turn the TV on and try to distract myself as I feel my crotch bulge slightly, making me cross my legs. I take the last part of my chocolate without thinking and regret it slightly, but unable to go back before gulping it down.

I can't help but sniff her scent as we sit here, only now smelling her heated musk underneath her perfume. It makes my cock bulge harder and I know the scent is wafting into the air. My sister takes a sniff herself, looking at me for a second before blushing and looking away. The tension builds as we stay there for a while as she takes more and more of the chocolate, the scent of her heat becoming much more prominent.

"Don't look at me like that, dummy." She says in a slightly weak, lust filled voice as I look at her.

"I'm just looking at you sis, I'm just a liitle distracted."

"Well, at least I have reason to be horny, you're just high."

"You're high too, but your horniness is biological."

"Exactly I have to keep on dealing with it, even with medication it's still a pain." She says as her legs move around slightly, seemingly out of discomfort.

I can't take my eyes off of her legs and thighs as she does this, imagining how they'd look in front of me, without anything on... presenting her cunt to me to claim... No! She's my sister! I look at her face and she seems to be in her own world, blushing and panting deeply. I can't take it anymore and I get up from the couch, going to head out the room before she grabs my arm. Our eyes meet and she moves my paw to her breast. I have the instinct to pull away, but the soft warmth of her tit makes me freeze up.

She's my sister... She's my... sister... oh fuck she's beautiful...

"I... sister..." is all I can say.

"I know how you get when your high, I... I get like that too... I need you to help me with it, I can't go through my heat like this."

"How... what do we do?"

"I don't know, how about we just... go with the flow?" She says as she moves up to meet me, her body pressing up to mine.

"I'd... I'd like that..." I manage to say as I look down at her bosom.

"Like what you see?"

"Oh yeah, baby."

"Wanna see them out in the open?"

"Yes, sis... please."

She smiles as she gets up and starts to undress, first her trousers, then her top, and finally her bra. She leaves her underwear on as her bra falls to the floor. I look over her large breasts, the fullness of their weight appearent to me as I move a paw lose to them. They feel nice and warm in my grip, my paw pads running over her nipple. She moans out and moves a paw into her panties, fingering her pussy lusftfully.

I push my sister against the wall softly and kiss her deeply, pushing my tongue deep into her maw. She kisses me back and fights my tongue with her own, lapping and teasing between out lips as I unbuckle my trousers, letting them fall to my ankles before flinging them away. She continues to finger herself as I kiss her, whimpering and shuddering in my grip.

"Such a good puppy," I manage to say as I pull back, panting slightly.

"Fuck me alpha..." she whispers into my ear.

"What was that?"

"Don't make me say that again, dummy."

I pull her panties down slowly over her wide hips, watching it run over her fur before it falls down to the floor. Revealing her folds as she pulls her fingers out, licking them clean softly. I replace her finger sign my own between her legs and find the warm, wet, musky folds, gaining a moan from her lips. I spread her lips and let a third finger up into her pussy, getting to the knuckle easily.

"You're such a good girl little sis," I say as she hugs me.

"Keep going dummy... I need you..." She moans out and bucks against my finger.

I chuckle softly as I move my paw from her folds to her ass, pressing my tip against her warmth. Her folds give a little as I press up against them, covering my tip slightly. She calls out loudly as I do this, gripping my back as her folds tighten and ripple around my tip.

"Oh fuck... sorry, I've not done this before." She explains weakly.

"You mean that you're...?" I half ask.

"So what? I'm a 21 year old virgin, I got my hymen torn when I was 17 so no one ever questioned it."

"Nothing is wrong wih that, it's just I never knew."

"Why would you? You're my brother, we don't talk about this sort of stuff."

"Well, we're about to do this sort of stuff." I say as I start to push into her tight folds, feeling her open up to my shaft.

She moans out and grips me tightly, her hot breath rolling past my neck. I grip her thighs and bring her legs up around my hip, bucking into her warmth excitedly. We embrace and fuck like the animals we are, my legs straining slightly as I carry her weight. I use this as a reason to grip and massage her perfect thighs.

"Oh fuck brother... you're so good..." she moans out breathlessly. "I can't believe I waited so long!"

"So are you sis!" I growl as I push into her, my knot growing as I repeatedly enter her no longer virgin hole.

I kiss her deeply and buck faster and faster into her, my knot beginning to pull on her insides every time I pull out. She groans as I pull my knot out, bringing me closer to her as I do so. We breath deeply through our noses as we fuck, buck and make out together, forbidden love between siblings, passion between blood.

I feel so close to cumming into her that I almost want to pull out and splatter her belly. But she keeps me buried deep in her warm insides, feeling like she's close too. We work towards making each other cum, not caring about our own orgasms. We keep our lips locked and our tongues interlaced as we build to a joint orgasm as I knot her.

Our bodies twitch, buck and cum together, our combined juices dripping down between our legs. We cum and make out for a blissful eternity as the heat of our lovemaking hitting us. I let her legs down and keep her up against me, our lips pulling apart in deep panting between us.

"Oh fuck... holy shit..." I manage to say, nuzzling her cheek.

"Fuck... that was a mistake..." she says and nuzzles me back.

"One of the best mistakes we ever made high."

"Shit, I'm going to have one hell of a headache."

"Don't worry, I'll be here to cuddle it away."

We stay together like that until we pull apart, going up to my bed and sleeping together. Waking up to my sis not being in heat...
