“There are only a few things you can survive on,” the scientist says maliciously. His eyes have a way of making you feel even more naked than you already are. You try to cover your privets with a your fluffy fox tail. The soft fur tickles and just makes you even more horny and awkward. You're trying to concentrate.
“You have a very specialized digestive system now, my fox slave. But luckily, you're able to survive on nothing but your new diet just fine. While foxes and humans are generally omnivores, you are a cumnivore. That is, you have to eat cum. And you will need to regularly receive it from both ends. Oral and anal. Preferably at least once a day in both, though that will be considered a rather space diet for you and leave you craving more. Truth be told, I've made you incapable of completely satisfying your lust for cock. You'll perpetually be ready for more. Think of it as my gift to you.”
“Though cum is an essential part of your diet, you can sustain yourself by drinking fresh urine if needed. Though you'll need to drink a lot. Saliva is a good substitute, if you can get someone to spit in your mouth, but it won't be enough. You will be a living urinal.”
Adorable fox ears flat against your head, you glare back, trying to look tough, but you just come off as submissive. Your tail is instinctively tucked between your smooth legs. The fluffy fur ticketing them, making you squirm in place. God, you're velvet skin is way too sensitive. “No. You can't... I won't....” you insist.
The scientist smiles. “Oh, you can try to resist, but the longer you go without, the more the urge to fill your ass with a nice cock will grow. And it won't be satisfied until someone cums inside of you. Not even if you stick an eggplant in there to try to satisfy the craving. Same with your mouth.”
“You won't ever feel hunger in the since of literal starvation anymore. Your genetically modified organs are far too efficient for that. If you go long enough without being fed your new source of food, your body will simply go into status. Like a doll. Perfect for storage and transportation. But you will dream. And by that point you'll be so desperate to be used for sex that that's all you'll ever dream of. Wild and unconstrained sex. But always unfulfilled. Endless edging. By the time someone fucks you back awake, you'll be begging for sex like a slut. A literally sex starved slut. Even so, remember, I made it impossible for you to achieve orgasm. Having others orgasm in you will be all you can think of.”
“Already, I bet you're mouth is starting to water at the thought of having a nice big cock on your tongue. Or someone pissing right down your throat.”
You clench shut your mouth, trying to deny that what he just said was completely true. In fact, your ass also has been feeling lonely and neglected for some minutes now. Empty and in need of filling. And it's getting worse. This can't be true!
“I'm a prince! You can't humiliate me like this! You can't!” There are tears in your orange fox eyes.
“Oh, but I can. And with time, you'll learn to love being treated this way. I have so many plans for you. You have no idea. Now, shall we get started?” The scientist pulls out his cock. Your large, slitted eyes lock onto it automatically. Petrifying you between the desperate desire for cock and your royal pride telling you to run away.
