I'm twitching again. One assistant is right behind me now. I shiver as the cold lube touches my asshole. Before I know it, he or she is pushing a finger inside of me, stretching me open. I can barely suppress a moan. It just feels so good to finally get touched.
You see, they keep our libidos at a maximum level. In other words, they keep us horny ALL-THE-TIME. They do it with some sort of drugs they mix into our food or water. I'm not sure what it is they use, but basically, it makes you want to fuck all day long. My dick feels raw most of the day from chafing against its cage. And some days I literally can't walk around without leaving a trail of pre-cum. The assistant is retracting her three fingers, and I feel her placing a large device against my opening. It smoothly slips into my asshole and presses right up to my prostate. When they flip the switch, a soft humming reaches my ears, and I can't hold back my moans anymore.
My prostate is being milked with soft pushes and vibrations and there's nothing I can do. My breathing quickens, and my dick is now painfully strained against my cage. It feels like it's about to explode. God... what I wouldn't do to be able to get fully erect right now. The first months I was here, I found it degrading how they would milk me without my consent, without any pleasure, simply for the act of emptying my balls. But now, I've gotten accustomed to it. More even, I depend on it. I crave it. I can't hold it any longer and I feel thick clods of cum shooting from the top of my dick, through the little slit of the cage. As usual, the volume is impressive.
The first assistant carelessly pulls the device out of my ass, causing a slight yelp to escape my throat. "Clean," the second one orders.
I immediately turn around and vigorously start licking up my cum. I dislike this part, but disobeying is not an option. I know I would be severely punished for hesitating on a direct order. Even after they turned their backs and left me, I keep licking the spot, terrified of doing anything other than a pristine cleaning job.
