With a belly full of milk and a pussy full of cum, it's not hard to make her accept them.

Ginger looked down at the groaning and murmuring latina, Micaela's head lying on her soft udder, the weight forcing small rivulets of milk to run from her teats. On the one hand, the red-headed cow morph was more than a bit sad that she'd have to share her step-sister's magnificent dick now, but having a new herd-sister more than made up for it. Where had that term even come from? Ginger didn't know, but it just felt... right. Raising her head, she looked at her bull lovingly who was sitting on her muscular butt, leaning on the door, a weary but proud smile on her face. Lily's impressive monster was slowly softening, the flared head retreating into her sheath. Ginger began salivating at the sight, pussy already moist from Micaela's **** sucking.

"Phew, your milk and my cum together as pretty damn potent, huh?" Lily grinned, glancing down at Micaela's still-swelling ass, biting her lip at the incredibly arousing sight.

"Mhmm... And we gave her another dose just now! Do you... do you think she'll grow an udder too? I kind of... feel weird being the only one having one of these things..." Ginger murmured, blushing and looking to the side. Her hands kept running over the latina's head, who briefly tensed up at the word 'udder', earning soft cooing noises and some gentle caresses from Ginger which caused Micaela to calm down again.

"Don't know... I'm not making any predictions. None of this is even remotely logical or sane, so we'll have to wait and see."

"Yeah, you're probably-- aww, her ears are becoming like ours!"

"What?!" Micaela squeaked, shooting up into a sitting position and sending her quartet of tits bouncing around wildly. The latina clapped her hands over her ears, wincing as the palms hit the softening, already much more sensitive cartilage. "No, no, no, this isn't happening!"

Ginger couldn't stand seeing her new herd-sister so distressed and scooted forwards, letting her hands run over Micaela's upper pair of watermelon-sized tits. The cow morph remembered how Lily's stimulation to her ears had helped her accept the changes last night, but Ginger also knew that she was probably to weak to **** the latina's ears away from her head. But luckily, Micaela had many more erogenous zones...

The tender caress of Ginger's fingers alone was making the newborn cow morph shudder and tremble with lust. Micaela's face quickly became flush with arousal, lips parting slightly to let increasingly ragged breaths flow over them. Together with the latina's jaw, her arms began to slacken, slowly shifting, floppy ears with a Holstein pattern peeking through her fingers. Ginger leaned in closer, running her thumbs over Micaela's puffy areola and softly blew air onto the lengthening ears, perfectly aware how it would feel for her herd-sister.

Micaela's eyes fluttered at the sensation, her head rolling back slightly as her mouth opened into a wide, pleasured expression and her arms fell away from her head, the latina's fingers instead digging into the pliant flesh of her lower tits, rolling the thick nipples between one finger and thumb. Lily, meanwhile, had moved closer as well and was now sitting on her haunches behing Micaela, sliding forwards until her crotch pressed into the latina's back and her muscular thighs pressed into her waist.

Ginger's step-sister then leaned forwards and began nibbling on the rounded tip of Micaela's twitching ear, her reward a deep, heartfelt moan from the Holstein heifer. But the bredding bull wasn't done by a long shot - her strong hand snaked around the latina's body, caressed her toned belly and inched ever downwards, Micaela gasping and twitching with anticipation.

"Oh god, what are--mooo! You doing to mooo--me?!" She **** out between pleasured gasps and moos, pressing herself into Lily's chiseled body, leaning her head back against her bull's shoulder, giving her easier access to the latina's sensitive ear. Her herd-sister followed her, pressing her udder into Lily's arm, sandwiching her stiff teats against Micaela's belly, Ginger now gasping herself as her step-sister's muscles slid over the sensitive pink flesh and the redhead cow's own prodigious breasts pressed into the latina's quartet, their combined ministrations making a combined six teat-like nipples buzz and throb with pleasure. And finally, Ginger was in reach of Micaela's other ear, wrapping her soft lips around it.

"HaaaAAAH!" The latina breathy moan rapidly rose in volume, her hips bucking and forcing Lily's arm into Ginger's udder, the cow morph unable to keep down a lusty moo of her own. "Oh god, don't--moo, don't stop, right there, oh FUCK!"

Ginger could feel the muscles in her bull's thick underarm shift and twist, realizing that Lily's fingers had to have reached the Holstein's pussy and were now going to town. The cow morph's own cunt twitched and drooled empathetically, and Ginger intensified her efforts on Micaela's chest and ear, intent on showing the latina how good her new body felt, even though she was a hair's breadth away from jamming one of her hands into her snatch and stir up her juices.

"Nnnmoooo, YES! I think I'm--I'm--moooOOOO!" Micaela lowed loudly, liquid arousal splashing all over the floor and Ginger's thighs. Both cow and bull didn't slow down neither mouth nor hands, and soon had the latina twitching and writhing between their bodies, unable to form coherent words, instead mooing and moaning uncontrollably, head rolling limply over Lily's muscular shoulder.

Finally, despite Ginger's and Lily's efforts to the contrary, Micaela's climax began to ebb, and the panting latina went slack, her bull's body keeping her upright. Ginger let go of Micaela's throbbing nipples and wrapped her arms as far around her herd-mates as they would go, Lily' following her example, her bulging arms forming a protective circle around her two cows. Ginger felt herself cushioned by six well-developed tits between them and rested her head on her herd-sister's shoulder, careful not to poke anyone with her horns.

"How... how is this even real?" Micaela whispered, and Ginger felt her fuzzy ear move and slide over her head in agitation. "It felt amazing, but my body... and you two..."

"Sshh, it's alright, little heifer," Lily's sultry voice interrupted her. "It's alright. You're my herd, and I'll take care of you both. Whatever comes."

Ginger felt shivers run through her herd-sister's body at the sound of their bull's voice, the ear's movement stopping, and she smiled happily. Their herd was growing, given the way Micaela melted into the double embrace. It made a warm, fuzzy feeling rise in Ginger's belly.
