Done for the day

When you return to the farmhouse just after sunset you are quite thoroughly spent. You pass your mother and older sister in the kitchen, shoulder to shoulder as they prepare dinner and you wonder how their day was.

As you climb the stairs you see your twin sister Jenny at the top of the landing, her hair wrapped in a towel. She wears a long white t-shirt and nothing else. The shirt has the picture of a cartoon giraffe on the front, bought from the giftshop at the Zoo a few years ago. Despite extra large being the only size they had left your sister had still successfully begged for one.

She notices you ogling her because dear god she looks so sexy in it with her bare slender legs exposed, her skin so soft and freshly washed.
"Don't worry," she says, walking away from you with a smile as you stare after her. "I left some hot water for you." You blink dumbly for a few seconds after she disappears into her room and remember that you did come up to use the shower. You wish you had returned home a little earlier, then you really could have saved some water by joining your twin in the shower.

The thoughts get washed away as you stand under the steaming showerhead, the dirt, grime and stickiness of the second day's farmwork running down your body and swirling into the drain. The soreness of your muscles mellows thanks to the heat, which lasts just long enough for you to get properly clean. You smell dinner in the air as you step out of the bathroom, towel wrapped around your waist and wonder if you should bother dressing.

You do decide to pull on a pair of shorts and rejoin your family in the kitchen and help set the table. Everyone else has at least one piece of clothing on, but it all seems so perfunctory to you now. The door swings open, your father returning just as everybody is ready to sit down.

"Welcome home, daddy," your sisters chime in unison, which they used to do a lot, but their intentions sound so different now. Your father smiles at his kids as your mother moves up and kisses him on the cheek.

"How was Roni?" she asks him as he moves over to the sink to wash his hands before seating himself.

"Good good," he says with a measured nod. He passes the bread basket down the table and when it makes its way to your end you take a roll and bite into it hungrily. "The alpacas got a little rowdy while I was fixing the fence so that slowed me down a little," continues your dad as he helps himself to some gravy. Your mother laughs at this starts to butter some bread.

"I'll bet they did," she adds knowingly, smiling pleasantly to herself.

It takes you and your twin a moment before you realise what that meant and your memory of the McDonald ranch makes you stop chewing. Roni McDonald's ranch was home to slightly more 'exotic' animals. It had been about a year since you visited her acreage but you did remember the morphed alpacas and llamas and goats... ostriches ... or where they emus? And alligators! Crocodiles? Too many things are popping up in your mind and you can't remember if they are creatures on Roni's Ranch or you had seen them in the Zoo. You want to ask your father more but your sister's mouth is quicker.

"You fucked Roni's alpacas?" Jenny blurts, silencing the table for a second, blush rising up through her lightly tanned cheeks.

"Roni too," replies your father with a grin. Your eyes widen, but neither your mother or your older sister Betty have any reaction to this. Now you picture Roni... an older lady, probably not that much older than your mother to be honest but she did sport a full head of graying hair. Admittedly she was still a very fit and attractive woman, having worked on the ranch her whole life and keeping a very healthy and active lifestyle. You remembered her well...

Jen drifts out of her own reveries and looks over to you, her scandalized expression mirroring yours. You hear Betty giggle now, having fun with the revelations of her two younger siblings.

"Wow," is all Jenny can say before the meal resumes. You reach for your glass of water because your mouth is unnaturally dry and that prompts Betty to stand.

"You two should drink more milk," she says, fetching a pitcher from the fridge. She takes your glass of water, tipping out what remains in the sink then refilling it with cow's milk, doing the same for your twin. You and your sister look puzzled as you pick up the glasses. "Oh... right I think we forgot to tell you two about the milk," says Betty, sitting back down and passing the pitcher to your father.

"Ah we did forget," he says, filling his own glass. You regard the white liquid suspiciously and your mother smiles another private little smile.

"The milk from our cows is special," explains Betty. "It contains proteins and enzymes that enhance your... reproductive functions. For women it improves our stamina, heightens our sensitivity while keeping our elasticity from fading and has mild anti-ageing properties."

"Our... elasticity?" wonders Jen, blinking slowly.

"Helps keep our pussies tight," answers Betty with a wry smile. You swallow because your mother flashes you a similar look. "Among other things. And for men it's even better," continues your quite knowledgeable older sibling. "You probably noticed you can ejaculate a lot Jon, and quite often. At this point your refractory period will be minimal, and your semen generation is probably... I don't know... ten times faster than someone who hasn't been drinking our cow's milk their entire life. You probably didn't notice when you were growing up, since mom and dad didn't leave us with a lot of time or energy to jerk off that much after finishing our chores. Probably assumed you were one and done huh? Don't worry, the stuff is all natural. That kind of milk is just what fuck farm cows produce."

This new information has you speechless and you think back to the rather hectic day of farmwork. You did cum a lot. You stare at the glass in your hand, the droplets condensing on the cool surface trickling down your fingers. Whatever was in this special milk it didn't seem to have anything negative about it. You had been drinking it all your life, thinking it to be just a normal source of calcium. You were a very healthy person. In fact... you felt like more than that. You took a sip from the glass, that familiar creamy flavor unchanged despite the revelations. You did always like your farm's brand of milk more than others. You down the glass thirstily, your sister doing the same next to you.

Dinner continues and finishes normally after that, with you and Jen washing and drying the dishes respectively as your parents go watch some television in the den.

"So which farmyard sluts did you get balls deep in today?" Jenny asks you with a grin. The plate you were about to pass her almost slips from your hand but she catches it deftly. She titters at your open mouthed shock until she bumps you with her hip, your bare legs brushing briefly. "Some of them like dirty talk," says your sister wistfully as she puts the dried plate down. This makes you nod, fond recollections of the day making you smile. You tell her about what farmwork you did, and who you did, and she tells you about her day as well. Jenny... well Jenny did service a few female animals but she also took care of an eager lineup of males. Bruce the bull was one of them. "Fuckin' hell a bull's cock is so long," she says, her grip tightening around a dozen dripping knives and forks. "And thick, my god... but he came before I could fit it all inside me. I think he was a little excited to be having me," she smiles. You aren't sure why you are grinning from ear to ear but hearing about your sister getting fucked by a big bull's dick makes you happy. "He came buckets," she adds. "Literally. We store the stuff in like, miniature versions of those milk canisters." You nod at this information as you work the sponge. "Oh my god but the horses... " she continues, enthused. "Horse precum tastes like... like runny honey. Can you believe that?" She takes the crazy grin on your face as a 'yes'. "They seem to have a bit more stamina than the bulls. But not by much. And I think that's the point," she says, scratching her chin. "If the animals fuck a human they just cum faster? Or something. I think it's the way we smell to them as well... and taste... heheh..." She is getting a little giggly at her memory and bites her lip. "That's what Skymark told me anyway. While he was sticking his amazing tongue up my pussy."

"Fuckin' hell," you groan, now able to imagine the chestnut coloured racehorse with his muzzle between your sister's legs. She smiles and bumps her hip into you again.

"I always wanted to ride Skymark," she notes cheekily. The horses that stay at your farm do a lot of different things. Some work on the farm while others perform or race professionally. Skymark is an Australian thoroughbred, relatively young compared to a couple of the other racers he shares the stables with. "He was a good ride."

The stories are obviously getting the both of you worked up and as you dry your hands on the teatowel Jenny sidles up to you, pushing her hip into yours and staying pressed up against you this time. "So that milk makes you cum a lot huh?" asks your sister, looking down at the tent in your shorts.

"And it also keeps your pussy tight even after you fuck big fat horse cock," you say, making the smile on your sister's face widen.

"I love this farm," she says. "I mean... I didn't mind working here when I was a kid, and I loved all the animals and stuff, but now? I love this place."

"Me too," you agree. "I ... I love being a farmer. I never thought I'd ever say that but I can't wait to work again tomorrow."

"I know right? I always wondered how dad could be so chipper every morning," says your sister.

"What a secret to keep," you add. "Not to mention... the other stuff." At this Jenny wiggles her eyebrows then turns into you, her warm body presses flush with your hardness. She's not wearing anything under that long shirt and the fabric of your shorts is paper thin.

"This other stuff is... pretty nice too," she sighs. You nod then lean down to kiss her and she hums against your lips.

"Guys," interrupts Betty, her head popping into the kitchen. Neither you or or twin react immediately, your kiss breaking slowly. There was nothing to hide in this house any more. You both came to realise this rather quickly, though you do turn to the big sister and give her a curious look. "That's sweet but it's dog grooming night," she says. "I just let the girls in so... make them feel at home. In your rooms."

"Dog grooming nigh- oh my god..." says Jenny, her jaw dropping. You remember that once a week the morphed farm dogs would spend a night in the house, and your family would take time to brush their fur and clip their nails. Or at least that's what you and Jenny did... the dogs would then sleep in either your parent's room or your Betty's room afterwards.

"Yeah we can skip the first bit now," says Betty with a grin before disappearing upstairs. You and your twin sister look at each other for a moment... then bolt up to your rooms.

You both pause at your respective bedroom doors and share one last glance with each other.

"Tell me all about it tomorrow," says your sister as she gently pushes through her door. You nod and open the door to your own room.
