You do some actual work until lunch time.

It was, to say the least, a very eye opening morning of farm work. After you watched your father finish off the last cow, who mooed so loudly she got a little hoarse (ahah), you and Jenny helped move the canisters full of milk into storage ready for pasteurisation. It was a little odd doing the work naked, but you didn't mind seeing your fit sister's body as she sweat. Occasionally she glanced down at your constant erection. Your father seemed to be hard all the time too and you wondered if it was because of naked his daughter or if every day in the barn was like this.

Later you and Jenny find your older sister Betty in a large wire pen where half a dozen fully morphed chickens are sitting in a circle of nests around her. She is naked and sweating and and wrist deep one of the chickens. The morphed chickens are easy to tell apart thanks to their crests. Each one actually liked to dye or style it in some way which helped with identification.

One with a shiny green crest is moaning and clucking around your sister's fist and your erection throbs as you watch. You can see the bird's muscular and feminine form under her feathers as they flare with her orgasm. Betty pulls her fist out hurriedly with a sucking wet sound. The chicken keeps shaking and something starts to emerge from her tight pussy. The other chickens watch intently, as do you and your sisters, as the oval coming out of her cunt makes her twitch. Shockwaves of pleasure move through her in visible ripples, feathers ruffling. She squeezes her meaty tits with her talonlike hands, head thrown back. The thickest part of the egg is finally pushed out and she groans with relief as it plops softly onto the hay. She lowers onto it and rubs her swollen lips over the shell, slick juices dribbling out of her and onto the almost football sized egg.

You learn that, similarly to cows, the chickens need sexual stimulation to lay eggs. Judging by the size of them you see why. You notice that each chicken in the pen has a very gooey egg next to them now, no doubt thanks to Betty's hard work. She seems to be giving herself a little reward for a job well done and strokes her own pussy. It was funny fast you were getting used to all the displays of sexuality around you now, all of which involved your family and farmyard animals.

"That was pretty hot right?" Betty says with a smile, looking up at you and your sister. You both nod, then proceed to help collect the eggs, placing them into large baskets. You recognize the chickens as your move around them, each looking quietly satisfied. Some of them stroke your legs or wish you and Jenny happy birthday.

"It's funny finally seeing you in here in the Big Barn," one of the chickens say, who your recognize is called Bibbi. She has a short red crest that's slicked back, larger breasts than all the other chickens and looks incredibly soft, her hips wide and thighs thick and meaty. "I see you staring when you come feed us. At these." She lifts her large tits up in her arms, squeezing them together. Your cock throbs.

"Yeah," you admit, at first wanting to avert your eyes until you realise it's fine to stare so you do. "You have nipples. I wonder why you have nipples." Bibbi looks down at her tits and her hands instinctively go to her nipples, these sharp pink nubs that she tweezes between her fingers. It was a fair question, you thought, since birds in general don't breast feed.

"They're not really nipples," Bibbi says, still massaging them. She obviously enjoys it. "It's just how our breasts ... end?" she tilts her head in though, her fingers running down her cleavage. "Just a result of how we evolved I guess. We hatch our chicks in between our warm tits. Tits just like growing into this shape I suppose... and to a point?" She seems unsure of her hypothesis but you nod, caring less and less about the explanation as you watch this sexy chicken playing with her breasts. You make a note to probably drop by the Egg Collection Pen tomorrow... eyeing Bibbi's puffy pussy lips.

You lift a basket in each arm full of big chicken eggs and follow your sisters out of the pen. Looking over your shoulder you see Bibbi's beak curl into a knowing smile at your attention. Next time. Definitely.
