Your sister helps you fuck a cow.

You look to your sister, whose cheeks are slightly flushed and you're almost overcome by how much of a pretty little thing she is. You wish your cock isn't just pressed up against her through all these layers of clothing, and through your twintuition you can tell she's sharing these new burgeoning feelings. But there's work to do right? These cows need... milking.

You and your sister strip down by yourselves, and while you had a quick image of tearing Jenny's clothes off in the barn you're kind of captivated watching her strip on her own. She's not doing it in any particularly sexy way, but as she sheds the baggy layers of farm clothes and reveals her firm lithe figure you feel your erection harden. The sound of Pumpkin moaning in ecstasy is also contributing to it.

"Mmm... nice young cock," sighs Pumpkin longingly, staring at your now exposed erection. You feel your sister's stare on it too and it sends a chill up your spine. The milking machine whirrs again as Pumpkin reaches another orgasm. Now both naked you and your sister creep back behind the wall, the smell of horny cows now quite noticeable with all of the colorful round asses bobbing in the air. The sound of your father slamming into Pumpkin is only slightly distracting as you and your sister survey the parade of quite frankly delicious looking pussies lined up before you.

"Pick a cow?" suggests Jenny. You can tell how torn her attention is in this situation. Her father is to her right, fucking the brains out of a cow, while on her left is her brother sporting a throbbing erection and waiting for you to choose a vagina to pleasure. They all looked like great candidates to you, but wanting to give Pumpkin some space you decide to go one more cow over, to a white one with large black patches over her fur.

Jenny walks up to the eager ass and gently pats a cheek.

"Mmm!" says the cow on the other side of the wall.

"Olive?" she says, her brain working some normal things back into the fore, like the names of each cow.

"Yep!" Olive chimes happily. "I'm so glad to be your first!" She glances over her shoulder, flicking her dark, shoulder length curls to reveal her wide smile. She had a round patch of black fur over one eye and she winks at you while shaking her ass.

You're slightly unsure of where to start so just watch as your sister gently rubs Olive's big butt cheeks with her palms. She spreads her crack slightly and you get a peek of the cow's puckered asshole. She looks amazingly tight back there, like a human's but with a fine layer of soft fur.

"She's so wet," your sister says as she starts to stroke the cow's lips. You hear Olive hum as you go in for a closer look. She is indeed very wet, her gash glistening. Jenny uses her fingers to part her lips and she starts to leak, the clear liquid running down her mound, soaking the short fur.

"Moooore," Olive groans, slightly muffled by the wall. Wanting to please her Jenny waves you over. She looked like she was about to actually grab your cock but decided against it in the last moment. You walk up Olive and you rest your erection against her warm opening. Just this contact is sending jolts through you but you know there's more to do and slide the head of your cock down and line it up. After a beat you move your hips forwards and slowly slide into her, eliciting a prolonged moan from the horny bovine.

"I can't believe how hot this is..." says Jenny, sort of breathless and watching as you bury your cock into the cow's pussy. You have to agree. It's amazingly hot, like you dipped your cock into uncomfortably warm water, but also the fact that you're finally fucking one of these sexy morphed animals is turning you on so much. Not to mention having your naked sister so attentive next to you as you pleasure this bent over cow. After a few seconds of her watching how you saw in and out of Olive, Jenny's eyes flick up to your face. Seeing your expression of ecstasy she smirks. "I bet that feels amazing."

You swallow nervously and nod, picking up the pace as you fuck Olive. The cow moans and shudders and spreads her legs.

"So fuckin wet," you say, which makes your sister nod. You hear how much liquid is getting pushed out of her pussy and look down. Your sister's hand gently brushes past your junk as she reaches for Olive's clit. She finds the furry nub with her fingers. The wetness having leaked down, she spreads it around. Olive starts to tremble at the pressure being applied to her button and you start thrust harder.

"Mmm yes," Olive moans. "Yes! Fuck me! I'm gonna ... mmm... yes... mmm....moooOO!" The cow starts to climax, rocking on your cock as your sister you keeps rubbing the clit. You hear the milking machine whirr as her pussy flows with a thick fluid, pulsing around your cock with each orgasmic convulsion, drenching your balls and your sister down to the wrist. Your cock throbs at the sight and the smell, a light scent of fresh cut grass in the air now. It feels like she's milking you with her pussy.

The tan colored cow between Olive and Pumpkin suddenly groans too and you turn to see your father's hand deep in her pussy while he's still fucking Pumpkin. He has four fingers in the tan cow, stretching her out, legs shaking. Pumpkin looks to be shuddering too and you wonder how many orgasms she's had since this whole thing started. Apparently enough for now because the brown cow slumps, her weight bearing on the wall as your dad pulls out of her. His cock is still hard as a rock, slick with Pumpkin's cum, and it looks like he hasn't orgasmed yet. His fingers are still in the tan cow and he moves over to her, replacing his hand with his hard cock seamlessly. He notices his son and daughter staring and smiles at them.

"Was just getting this one warmed up," he says as he starts thrusting into the sopping pussy. He grips onto the furry hips and rolls his head back. Jenny is super distracted by how close her father is now, in particular his cock ravaging a tight pussy right next to her.

"I'm warmed up too," Olive says, glancing over her shoulder. Her eyes lock with your. "Fuck me hard?" the cow suggests, spreading her legs further. "Pound me." Jenny looks down at her glistening fingers then to Olive's pussy oozing around your cock. You watch your sister walk to the other side of the wall to where the cows' upper halves hang out to be milked.

"Pound her," Jenny tells you though the window. "Go on."

You nod and start to thrust again, feeling Olive's muscles twitch around you. Jenny strokes Olive's face. "My brother is going to fuck you hard, Olive," your sister says to her. The cow can only nod as you pound her pussy. You watch through the window as your sister moves closer to Olive, still holding her head then pointing her snout towards her perky breast.

"Oh my yes please," Olive sighs, seeing what she's offered. Her mouth opens and her long thick tongue slides out. Jenny sighs as the cow licks her nipple then she presses her tit to Olive's face. She sucks on it eagerly, your sister rocked gently due to your slamming into the cow tasting her. "She's touching herself," Olive announces as she switches breasts, taking the nipple hungrily. You look up from the cow's round ass and see your sister's hand between her legs as Olive suckles on her. The cowgirl sounds like she loves all of the attention, hips bucking against you as she slurps on your horny sister.

The sound of your dad's grunt once again manages to take both of your attention. He's fucking the tan cow so hard you're surprised the wall isn't shaking.

"I'm gonna cum in you Lily," he groans at her, which also makes your sister gasp.

"Yes! Yes! Yes! Yes!" Lily the cow cries excitedly, rocking back hard on your father's cock. He grunts again as he unloads and Lily actually squeals in delight. She orgasms at the same time, her tits squirting audibly as the machines drain her and she drains your father.

"Oh god," Jenny sighs, legs spreading as she fingers herself furiously. "Fuck... that's...oh my god.." she seems completely lost in her building pleasure. You're basically barely functioning mentally either and can feel yourself charging towards a finish. This whole thing is so absurdly obscene you know you don't have long left. As if sensing how close you are Jenny locks eyes with you through the window and nods at you.

"Do it," she whispers. "Come on. Come in her."

That was enough of that. You groan, the sound coming deeply from your chest, and erupt into the cow. Olive writhes, spitting out your sister's tit to moan gutturally. You feel like you'll never stop cumming, jet after jet of hot cum pumping into the cow until she's overflowing with you and starts to seep out. You push in as deep as you can with your final thrusts and feel the the tight channel clamp down around around you.

"Moooooooo!" Olive moans loudly, her pussy exploding with a powerful orgasm, her muscles trying to push your pulsing cock out but you hold her down and keep yourself balls deep. The sensation makes her climax rebound and she cries out again. This second wave is enough of a show to send your sister to her own gushing end and she squeals as it rolls through her. Her knees give way at the same time the cow's legs do and they both slump onto to wall. Olive hangs limply in the window, breasts getting sucked on madly by the milking device on the other side.

"Holy cow that was hot," your father notes, standing on the other side of you, his hand resting on the ass of a very restless cow who was last to be served. He was fully erect again, obviously thanks to the show you and your sister put on, and he once again gives you a thumbs up.

You and your sister stare dumbly as he starts to fuck the next cow. Did he really just make a dad joke?
