It should fit the color of his fur. Erm, hair.

James eyes were closed in bliss, his whole body trembling with lust. His pussy was moistening again, nipples and teats throbbing. Lily's hand kept tugging and rubbing his left nipple, thin spurts of milk spraying out with every stroke. He pushed his hips back into his sister's crotch, **** to fill the throbbing need in his snatch.

"Mmmh, your pretty red hair gives me an idea, " Lily finally breathed after several minutes of driving her step-sibling wild. "How about I call you... Ginger."

"Hnnnnyeesss," Ginger moaned, arching her back and pressing her tits into her breeding bull's strong hands. It was as much an exclamation of lust as it was an acceptance of the cow-morph's new name. Grinding her expansive ass against Lily's crotch, Ginger could finally feel the blunt head beginning to peek out of her step-sister's sheath and began shaking her hips enthusiastically, coating the swelling glans liberally with her juices. But to Ginger's immense disappointment, Lily suddenly pulled back from her and sat up.

"But whyyyy," the cow morph whined, turning her head and upper body to look at her step-sister, one horn scraping over the hardwood. "I want you insiiiiide..."

Lily's face had changed at least as much as Ginger's. Her jaw line and cheek bones were much more pronounced, accentuating a face with sensual lips and loving eyes gazing at Ginger. The cow girl felt herself drawn into the stare, breath catching in her throat. But Lily's face wasn't the only thing that had changed about her - her whole body was rippling with muscle, biceps the size of a man's legs bulging on her arms, prodigious pecs lifting her modest breasts high, an eight-pack of abs leading to the one thing in the world Ginger couldn't live without anymore and which was now slowly extending out of it's sheath, sliding over thighs that looked as if they could crush pumpkins with ease.

"I know, little cow," Lily answered remorsefully, looking down lovingly at her step-sister. "And there's nothing I'd rather do than fuck you hard until all you can do is pant and squeal, but we have to take care of a few things. My room is a mess, I'm starving, and so damn thirsty..."

"Ooooh, I can help with that!" Ginger squealed, drawing herself up and lifting her heavy tits with both hands, rich cream dripping down from the enormous nipples. Lily looked at her smiling sister with wide eyes before a wide grin spread on her face and she tapped her lap to invite the cow morph to sit. Ginger was more than willing to follow that invitation, seeing as Lily's enormous cock was still slowly engorging and slipping out of her sheath. Straddling her sister's muscular thighs, Ginger sandwiched the swelling rod between her soft ass and Lily's strong legs, rubbing her swollen pussy lips over it. Even sitting on Lily's lap, Ginger was half a head shorter than her step-sister now.

Looking up at her, Ginger marveled at how her diminished relative size gave her a feeling of vulnerability, and yet how safe and protected her bull's strong hands caressing her sides made her feel. Ginger's udder was squished against Lily's abs, erect teats rubbing over the strong muscles with every move of either body, smearing the bull girl with milk. Lily let her hands slowly wander up her step-sister's back, the sensuous caress making her shudder and moan, finally wrapping her left arm around her upper body and cupping the back of Ginger's head in her strong right palm, pulling her closer. Their faces separated by mere inches, Ginger could feel her heart beat faster, a blush creeping on her face - was Lily really...

"MMMmmmh..." Ginger's surprised squeal, muffled by her sister's demanding lips, quickly turned into a sensual moan as the cow morph melted into the kiss, closing her eyes and relishing the intimate connection, her own arms wrapping around Lily. She could feel her whole front pressing into Lily's strong body - udder, tits and swollen belly awarding her yet more stimulation. Her lips tingled as Lily kissed her hungrily until Ginger returned the kiss, clumsy with inexperience, but no less **** for her lover's taste. She could feel her bull's cock expand and swell ever more, the medial ring soon sliding over her sodden folds, making her moan into Lily's mouth, eyes long since closed in bliss. Her step-sister's tongue came questing into Ginger's mouth, and she greeted the intruder eagerly with her own, the sensations making both shiver with excitement.

All too soon, Lily broke off the kiss, a thin string of saliva connecting her mouth with the trembling, slightly parted lips of Ginger. The cow morph was panting with arousal, juices seeping out of her pussy, coating the throbbing member she was straddling. Ginger's mind abuzz with pleasure, she looked at Lily through half-closed eyes, unable to form a coherent thought. Lily chuckled, smiling at the state her kiss had left her little cow in, and then let go of Ginger's head to cup her bountiful tit, prompting a lustful sigh. Moving their upper bodies apart, bending her head down and lifting the smaller cow morphs' heavy breast upwards, Lily sucked the thumb-sized, dripping nipple into her mouth and began to draw out the sweet nectar waiting within.

"Hnnmooo, yes!" squealed Ginger, roused from her lustful stupor in the very best of ways. "Suck my titty, milk me dry!"

In response, Lily pulled more of the squirting nipple into her mouth, until her lips formed a tight seal around Ginger's puffy areola, her tongue running in circles around the stiff and sensitive flesh in her mouth. Ginger could feel the milk draining from her breast, a tightness she hadn't even consciously been aware of gradually lessening and adding to the sensations racing through her body. She wrapped her arms around Lily's head gently, stroking her step-sister's hair as she suckled and teased on the cow-morph's tit, slowly emptying it of its nutritious contents.

"Do you like it, Lily?" she cooed, gyrating her hips to slide her silken pussy over the rock-hard pole under her, "Is my milk tasty?"

Lily's answer was an appreciative groan and a particularly strong suck, causing Ginger to moo lewdly. Considering her question answered, Ginger intensified the motion of her hips, intent on getting herself off from the feeling of her sensitive lower lips sliding over her sister's medial ring. Warmth was spreading from her gushing vagina, her udder pressing into Lily's muscular abs with every forward motion, milk squirting from the throbbing teats. Pleasure and a deep feeling of satisfaction flooded through Ginger, soft, drawn-out moos accentuating every sucking motion of her step-sister.

Soon, Lily had sucked her little cow's right breast dry and straightened her back, still sucking on the stiff nipple capping it, only to let it slip out so the soft breast fell back down on Ginger's chest with a meaty slap, jiggling wildly. The cow morph squealed with a mix of pain and pleasure, pouting at her sister's teasing before thrusting out her chest, the left breast now visibly bigger than the right and still sloshing with delicious cream.

"Aren't you gonna finish~?"

"Mmmh, your milk is simply divine," Lily answered, burping lightly. "Compliments to the chef."

Giggling, Ginger lifted her left breast up, and her step-sister dove down, greedily beginning to drink from the proffered nipple. The cow girl's soft mooing continued, as did the methodical, sensual motions of her hips. Trusting in Lily's strong arms to hold her, she let go of her step-sister's body to move her right hand under her bulging udder where she found her buzzing pleasure nub already peaking out of its hood. Beginning to pinch and play with it with two fingers, Ginger's sighing moos quickly turned into gasps and moans, lust quickly mounting in the face of this three-fold stimulation. Lily used her right arm, no longer needed to support Ginger's emptied breast, to grab and knead her enormous, jiggling ass, adding to the intense sensations.

"Oh god, keep doing that, I'm almost--almo--almoooOOO!" Ginger babbled as she felt her arousal hit its peak before her climax washed over her, sending her into convulsions atop the twitching pole under her - in fact, she could feel Lily's monster expand and jerk under her, even strong enough to lift her off her step-sister's lap! Had Ginger not been overwhelmed by bliss, she'd have been impressed this strength as well as by Lily's orgasmic discipline as she grunted and sweated to hold in her seed while still continuing her suckling.

Finally, Ginger felt her lust slowly diminish, breathing ragged and gasping for air. If sex would always be this amazing from now on, the pills were the best investment of all time! Panting, she smiled down at her step-sister's head, lips still wrapped around her nipple even though Ginger could feel her chest had now been well and truly emptied of its creamy milk. But Ginger couldn't deny her lovely big bull the joy of playing with her boobies - not to mention it felt amazing for her as well. After a few minutes of gentle sucking, Lily released the engorged nipple and straightened her back. She licked her lips appreciatively before giving Ginger a quick peck on the lips.

"I could live entirely off your milk. Forever."

"I'm so happy you like it," Ginger answered, a bit bashful at the praise. "Are you still hungry?"

"Quite a bit, actually. This body apparently needs a lot of food..."

With that, Lily suddenly stood up, effortlessly shifting the wooping Ginger into a bridal-style carry before setting off, her throbbing shaft bobbing up and down with each step, slapping into the cow morph's jiggling butt from below.
