Barely, the thing is mind-shattering

"MOO!" Kate yelped as Natalie **** herself into Kate's swollen snatch. Even with all the changes she'd undergone, nothing could've prepared her for Natalie's length or girth.

Kate's limbs began to tremble as Natalie's flat, broad head pushed further into her crevice. Had she not been thrown back on the bed, she would've collapsed from the sheer shock of what was happening.

"Fuuuuuuck. Your pussy is soooooooo good. I'm so glad I decided to stay!" Natalie moaned, pumping her cock inside Kate.

Surprisingly, it didn't hurt nearly as much as Kate thought it would've. It was more like her insides were being shoved aside, not being torn. As if her body was readily adapting, molding her into the perfect sex-cow.

"I can't believe it! Not only am I fitting her, but I'm starting to like it! I've never felt so.... full...." Kate thought.

As the two girls screwed, the milkers were working double time. The transparent tubing ran solid white with all that they were lactating, Kate and Natalie combined.

"You've got a nice quad of titties too, little cow." Natalie remarked. "Bet it feels real good when I do this!"

Then, Natalie grabbed one of Kate's udders and squeezed. Kate screamed with pleasure, the nozzle and her partner's grip were ravaging her breasts without mercy.

"My my, did you just cum?" Natalie asked. "And we've barely just started! This is gonna be a fun time!"

One hour later

They were finally slowing down now. Over the past 60 minutes, Kate had orgasmed 12 times, while Natalie had given her 5 creampies, and was now finishing on her 6th.

"FUCKING. TAKE. MY. LOAD!!!" Natalie shouted, blasting Kate's womb with another surge of her hyper-virile cum.

The girls finally gave out, going limp on the bed. The milk pumps sucked out the last of their bounty before running dry at last.

Everything was sore. Kate's hips, her pussy, her nipples, even her voice had gone hoarse from all the screaming and moaning she'd done.

Natalie was just as tapped out. For the first time in a while, her balls were empty, and she'd need a break to recover from all the dick-chaffing.

The door to their holding opened, revealing their escort squads from earlier. With tremendous effort, they hoisted up the two girls onto stretchers and transported them back to their own private residences.

There, at Kate's room, she was greeted by the chrome-masked overseer.

"Well done, Miss Upton! You and Miss Lynd have more than exceeded company expectations. The two of you together produced a total of eight gallons in just one hour! We're looking forward to more tests in the future, but for now, I believe you've earned your reward."

The man paused, clearing his throat.

"The cows come home."

Kate felt something inside her mind click. A mental block had been removed!

"There, you should have your voice back. See for yourself." he suggested.

Kate paused, searching for the words that perfectly summarized what she was feeling. The afterglow of sex, getting her voice back, what words could possibly give meaning to such inner joy?

Her lips parted at last.

"Mooooooooo!"
