"Fuck sis, your ass still feels so damn good!"

I'm pounding her buttcunt, her tiny body has gotten used to being mostly cock after months of me raping her while she sleeps. Her ass hangs open to the size of my cock all the time now, her gape obvious even just barely bent over. Mom still has no clue about it somehow, even though I'm pretty sure she's messed herself at least once.

I look down at her asshole, mesmerized by the sight of my dick sliding in and out of her. She's pretty loose but it only makes her ass warmer and wetter when I fuck it. In fact, right now her butt is squirting out butt cum around me, farting loosely and making her walls pulse around me. She cums on my dick at least three times a night, I think she must've been made for it. The sloppy grip of her buttcunt is driving me mad, I keep fucking her as I maul her flat chest. She's still a long way from puberty but her chest still has a bit of fat on it, she's chubby. Each time I drag my thumbs over her puffy nipples she shivers. Fuck, she's so hot.

I'm enjoying her sluthole when her eyes flutter open. She's done it a few times, but usually her eyes close almost as soon as they open. This time though, she looks right at me, clearly confused and groggy but obviously awake.

"Big bro?" she mumbles, wiping at her eyes. "What're... what are you doing..."

Her hole tightens around me and I moan at the sudden sucking sensation. She hasn't felt this tight in months.

"Fuckkkkkkkkk," I gasp. "Keep clenching around me, you slut."

She barks out whines as I violate her ass, disoriented. She has no idea what I'm even doing to her! It makes my crotch tighten and before I can stop myself I cum into her, pumping her full. Her guts are used to it but she isn't and she squeals as her bowels fill up.

"What is that? What's in my butt?"

Her cocklet is leaking and I rub the tip in the way that I know makes her cum fast. She shudders beneath me, spasming as I force her to cum with my hips glued to hers. She moans bonelessly as her clit leaks just a bit of pre and her ass suckles on me. I grind my hips upwards and her cock spurts onto my hand.

"Take my cum you bitch, you love my cum filling you up, don't you?" I don't even know what I'm saying anymore, pleasure overwhelming my mind, my only thoughts about making sure my little sister is plump with my cum. "Fuck, you feel so good."

I go back to thrusting into her even as my cock is overstimulated. She feels too good on my dick for me to stop now. It's almost painful as I push my cock in and out of her guts, my cum squelching around as I do so. Her head lolls back, mouth hanging open as I wreck her butt. I lean over and shove my tongue into her mouth, forcing it down her throat. She coughs and gags on my tongue, trying to push me away but I'm bigger and stronger and she has no chance of pushing me off of her. The feeling of her throat spasming around the tip of my tongue makes me moan and I start to tonguefuck her mouth. Her little tongue against mine sends me into a frenzy, my hips stuttering as arousal fries my brain.

I cum again, it straight up hurts as I shoot into my little sister, But fuck does it feel good. My body slackens, my dick pulsing as I fill her even fuller. She whimpers into my mouth as my tongue goes limp in her throat, blocking most of her air. She whines as she struggles to breathe through her nose. I keep humping her, my dick complaining about the continued sensation and then she tenses, warm wetness spurting against my belly. She fucking came from me filling her butt and tonguing her throat. She's such a slut.

I pull my tongue from her throat at last and she coughs as she gasps for breath. Each cough makes her clamp down on my cock, forcing a hiss out of me. I yank my dick from her and pull her up to my face before my cum can spill from her asshole. I shove my tongue fully into her butt, lapping up my cum. She moans as I clean her out, her round belly jiggling playfully. Her ass tastes so good, I can't get enough of it. If I could eat her out for dinner I would. The taste of my cum on top of it only makes it better. When my tongue gets tired I pull out of her. She's not empty, but she's definitely less full than before.

My mouth immediately moves upwards, enveloping her clit and balls in my mouth. She's so small I can fit all of it in easily, my tongue caressing her little sack. I lick the pre from her cocklet, only a faint musky taste present. I crave all of her, I want to taste every inch of her. I want to worship my little sister's body with my mouth. I suck on her, desperate for her to cum in my mouth. It doesn't take her long, the pre I'm rewarded with I suck down immediately. She thrashes under me, incoherent attempts at sentences forming and trailing off. I don't know if she's begging or asking what's going on, but I don't really care, my only concern is sampling her entire body.

I yank her up and attach my mouth to her chest, licking over her nipples hungrily. I suck and bite at her, tugging moans and gasps from her over and over. She's in my lap, straddling my legs. Her ass leaks cum onto my dick but I'm so caught up in sucking on her tits I can't be bothered to care. Eventually my frenzy dies down and I pull away for now. She's clinging desperately to me, confused and overstimulated. We're both soaked with sweat and I drag us to the bathroom, turning on the shower.

She seems a lot less overwhelmed in there but she doesn't explode into questions like I expected. Instead she seems quiet and shy, willingly following me into the shower. I tell her to face away from me and the look she gives me over her shoulder makes my knees go weak. I know it's gonna knock me out but I need to fuck her mouth so bad. First I need to clean her off.

"Lift your tail," I say, and once she does so I pull her cheeks apart.

She squeaks at the sensation of warm water running into her loose asshole. Surely she's used to it by now. Her ass is wide open, my cum leaking from her sloppy buttcunt. I plunge my fingers into her, scooping my cum out of her. She moans as I basically finger fuck her, arms wrapped around my torso. Once I feel the slickness of cum wash away I pull my fingers out of her.

"Get on your knees facing me."

She looks up at me again but does so after a second of hesitation. I push my thumbs into her mouth and slide the tip of my dick into her. It barely fits, there's no way I'm getting much more of it into her right now but it's all I need.

"Stay like that," I murmur, jerking the rest of my length off.

She sits obediently, looking up at me and waiting for me to fill her mouth. It really doesn't take me long, my cum soon overflowing out of her tiny mouth. Watching her try to catch my cum in her hands as it leaks out of her mouth would be jerkoff fuel for months if I didn't have two perfect holes to dump my cum into instead. I pop my dick from her mouth and pull her up.

"You're such a perfect little slut," I tell her, and she just shivers against me.
