Relax and don't say anything

You relax and don't say anything, you are outnumbered, and it will be worse if you resist.

You are put on a different table on all fours. This table has a neck restraint, and you are held like an animal. The put an open mouth gag and start to talk about you like "The Cow"
You are confused and a nurse starts to explain.
"You've been chosen by the doctor for a special role, we're going to use you like a milk cow"
Your stomach churns, and the effects of the sedatives are less effective because of your adrenaline. The machine starts to beep alarming the nurses about your heartbeat. The nurse notices your fear and say.
"Don't worry, the worst part is over, but we will make more enhancements with the medicine, your genitals will be altered, optimized for continuous arousal to increase milk production."
Her hand slides between your legs, checking your clitoris and anal cavity. You moan, your legs tremble, you think that you are going to cum. "You're already responding beautifully" she takes some notes and continues. "You will be in a state of constant arousal, your engorged genitals will help you to produce abundant milk without the terrible side effects of the pregnancy."

The nurse takes a big speculum and inserts it in your ass, you moan with a mix of pain and pleasure.
Now, unfortunately, we need to expand your ass to accommodate the excrement plug, you are going to produce milk the whole day and we don't have enough staff to attend to all the cows.

The speculum's cold touch makes you gasp as it begins to stretch you open. The discomfort grows and when you start to moan in pain, she stops.
"Easy, it's over for now, this will ensure you're ready for the plug, the size is huge, made for a real cow"

You are left alone for a few hours, from time to time a nurse comes to control your rectum and adds some grease to avoid drying.
A few hours later the nurse enters the room again.
"It's time to expand you a bit more" she says, the speculum opens a bit more, the widening is causing severe pain, a strange sense of fullness, and at this moment you think that you are going to be torn apart. You sweat as she lubricates the exposed inner walls of your rectum, another nurse helps you to clean your face and forehead.

After 24 hours of ****, she says "This is it"
The speculum is turned one final time, stretching you far beyond your limits. You feel impossibly full, the grease easing the way for the speculum's widest point. "You've done wonderfully, the huge plug is next, and you know you're ready, sorry but we can't show you the results, the last cow fainted when she saw her own ass expanded like this."
Resignated, and humiliated, they move you to a dim room, full of other girls with empty eyes, connected to milking machines with huge plugs with thick hoses inside her asses. "Welcome to your new home" the nurse says with a smile.
You can barely endure the smell, you think that you are going to throw up.
You know that this is...
