Opening the Door

As the gate swings back you pull your eyes away from Betty’s butt and on the barn floor lays a thicc horse girl. Sort of? You’re confused by what you see for a moment with how much there is to see:

Her long blonde mane shimmers, crystal blue eyes widening as they see you arrive. Her tits are huge, bigger than even any of the cows you’ve been working with, her nipples like big pink plates. She is being milked, you see, her teets attached to the same kind of udder suckers used on the cows. Her thighs are thick as well, the girl is big where it counts. Especially her massive horse cock.

“Um. Hi…” she says shyly.

“Wha…” is all you can manage. That dick of hers is not just long but thick too. There it rests, hard and girthy on her paunched stomach, her tiny hands holding the thing like a cock shaped teddybear between her tits. It’s jarring but she is also so absolutely stunning a creature. Everything about her outrageous body screams ‘sex’. You look at the horse’s face again, noting the blush in the cheeks, wondering why you’ve never seen this specimen before. Then there’s a glimmer of recognition of a stallion you remember that you hadn’t seen in a while. “Clyde?”

“It’s Clara now,” Betty corrects you, and she kneels down next to ‘Clara’ the horse girl and places a hand on her fat cock.Your own throbs at the sight, at watching your older sister firmly rubbing this horse girl’s shaft. Clara moans at the attention.

“This is… amazing,” you say, and both of them smile up at your reaction. “How did this happen?”

Betty shrugs.

“I’m a genius,” she says.

“You are,” Clara adds, and her voice is so silky sweet you’d never recognise it. She reaches out for your sister who leans down and she kisses her creation. A switch gets flicked and the milking machines start up. The tender moan that escapes Clara’s lips breaks the lovely makeout session you were gawping at.

“I’m experimenting with new milk formulas,” Betty explains as she starts to stroke Clara’s cock. “Enhanced horse milk was the original idea… but then I saw some other ideas after Clyde told me how she felt more like Clara…”

The horse squirms under all the sensation being applied to her right now… those suckers drawing in her nipples, your sister’s soft hand caressing her cock. You’re sure it feels as good as it looks. “So… I developed new hormones and helped this girl become who she really is.” Your sister squeezes the horsegirl’s girth, she moans and a spurt of thick clear precum lands between her massive tits. “She’s a sweet little milking slut now,” Betty says, running her finger tips through the pool of glaze in Clara’s valley then tasting the fruits of her labour for herself. “And these magnificent tits we grew her can produce real milk.”

Your eyebrows are well and truly raised, not to mention the erection you have that’s pointing sky high.

“Real milk...” you say, considering this. With breasts that big it seems a forgone conclusion that they can lactate. Your mouth begins to water. The loving, appreciatively gaze that Clara looks up at Betty with is almost trance-like. Your sister waves you over.

“Come on, I said I need your help.”

You do as you’re told and find yourself kneeling between Clara’s now spread legs. Her testicles hang there, completely clean shaved, heavy and huge. Betty shuffled over and reaches a hand down. She lifts the soft sack like a curtain and reveals horsegirl’s tight little brown ring.

You sister’s other hand wraps around your cock, her fingers wet and gooey. She spreads the lube she’s gotten from somewhere up and down your shaft, and only when she goes back for more do you realise what it is. She’s scooping from the precum pooling in a little valley on Clara’s stomach and applies the slightly warm fluids onto your now achingly hard cock. Your sister’s soft hand and Clara’s slick fluids of arousal sends electricity through you. “Now... Clara only starts lactating when she cums,” your sister says, angling your cock down to that puckered hole. “And she cums hardest from getting fucked in the ass. Kinda like me.”

You’re not given much time to think about what you just heard as Betty starts to press you into Clara’s tight channel.

“Ohh...Betty… Jon...” Clara mewls. Her fat cock flexes and you watch a dollop of her viscous precum ooze out. Once you start to breach her anus you have to close your eyes. The lube is working but it’s still slow going with how cramped it is between those meaty cheeks. You let Betty feed your cock through and she places an encouraging hand on the small of your back. Once you pass the halfway point of your shaft you start to sink in faster. It feels like her asshole is sucking you in. You look down at Clara now, at her huffing pink face, those jiggling tits as her breathing quickens. That slab of meat that’s flat on her stomach keeps throbbing and dribbling. She’s gorgeous.

There’s a sound of liquid being suctioned once you finally fill her ass to the hilt, Clara wheezing girlishly. You see two tiny spurts of milk managed to get extracted from her tits from you bottoming out on her alone. This feels incredible. Clara’s swollen sack rests against your pelvis, you’re a little mesmerised looking down at them.

“Fuck her Jon,” you hear your sister say, and her words start to move your hips. You hold onto her thick thighs as you withdraw you iron hard rod from her anus. The way she pulls at your cock fills you with a lustful need and you slowly plunge back into her to sate it. Clara moans loudly at each stroke where you plug her back up, and you also mash up against her huge balls each time. You thought after such an eventful morning with your family you might last a while on the first job in the barn… but there’s just too many new stimulating sights and sensations.

As if she senses your end approaching, Clara locks her dazzling blue eyes with you.

“Cum inside me… please...please cum inside me,” she begs. Betty laughs and wraps her hand onto Clara’s dick. Your sister looks at you and grins.

“Race you,” she says and starts to jerk Clara’s reddening length. The horse girl whines at the extra sensation and squirms. Her writhing and the added shudders from Betty’s working her grip on the horse all feeds into your cock buried in that tight, clenching ass. You’re sweating, not sure where to look… at Clara’s pretty face twisted in lustful agony, at her bouncing, giant pillows of breasts, nipples now distended a few inches into the suction cups... At her obscene horse cock that Betty’s is so enthusiastically jerking that she drools like the tips does with precum.

It’s hard to tell what happens first. You feel a lurch in the big balls on the girl and her cock swells. You feel your own dick throb in her ass and the world becomes jizz. Clara is spurting, her hot cum firing out between her tits, hitting her on the chin and mouth as she wails. You’re filling her ass with thick bolts of your seed, her rippling walls milking you. They hug your shaft with each pulse of jism you can’t stop pumping. You can’t stop flooding her with potent heat. The milking machine whirrs to life as those tits start spaying too. The glass tubes fill with white which get vacuumed away a second later, then filled again almost immediately. The pattern is almost like flashing lights, timed with each jet of sticky semen Clara keeps spilling onto herself, your sister milking her with her giddily at the same time.

You groan as you thrust one more time and finish your load, feeling some of it already leaking out of her asshole around your cock. The absolute mess that lays there on the soaked barn floor is not an image you’ll soon forget. Clara is festooned in her own clinging ropes, all over her tits and neck and face and shiny blonde mane. The milk machine winds down. Betty sighs, her own hands covered in lady horse jizz and she licks her fingers absently, cum running down her arm.

“I think I won,” you say, and both ladies just look at you and smile.
