A ten...
He didn't say what a ten meant. He told you what anything below a ten meant for you. Same for everything higher than a ten. But a ten exactly? The horse looks down at it, just as confused as you are.
"Hmm..." He says pensively. "Well, you're not free to go, but you're not ball stuffing..."
You're not sure what to feel. Relieved? You aren't going to be eaten by a giant horse's cock. That...that was a good thing, right?
The grin the horse gives you is all the answer you need.
"Satisfied with your worship, the snake considers its options. You would make for such a wonderful meal, but it has grown rather...attached to you."
The horse once again starts playing with his flaccid cock. Cum oozes off the tip, pouring onto your face as it 'talks'.
"You make for quite the obedient pet. Cute, too. Perhapssss I ssshall keep him assss a thrall."
"W-What...?" You squeak.
"Alas. The poor mage has done too good a job at pleasing the ferocious beast. He can feel the snake's magical power overwhelm his mind, drawing him ever closer to its veiny embrace. His journey has come to an end, but a new life of servitude begins."
You brace yourself for the snake's hypnotic attack, only to feel like an idiot when you realize the horse can't just hypnotize you. What he can do, however, is pick you up into the air, leaving you dangling by the leg.
"Helpless to escape its mighty grip, the snake drags you back, deep into its den."
You watch as the 'snake' is stuffed back into the horse's underwear. The article of clothing is barely able to contain its sheer size. He lifts his member up slightly, showing the sagging sweaty balls underneath.
"Please..." You whimper. "Have mercy."
The horse frowns, giving you a mock look of sympathy.
"I'm very merciful...but my snake? Not so much."
With that, he drops you down to the opening in his underwear. You scream the entire way down, your fall broken by his squishy, sagging balls. You can feel them already churning with a fresh load.
A snap from above seals you in your prison, trapped in hot, rank darkness, with only his steamy cock to keep you company. The member flops over you, pinning you between it and the sloshing sack. With his new pet trapped, the horse walks back up to the living room, eager to enjoy a long weekend alone.

You learn a lot about your owner in the next few days. You're always by his side, forced up close to his gigantic cock in a filthy pair of underwear he refuses to change.
The only times you're let out are when he has to use the bathroom. He never showers, never washes his hands. Never even wipes. He just does his business in front of you with a smile on his face before stuffing you right back in.
The other times are when he feels horny--which is often. The horse has an unbelievably strong libido. Probably spurred on by knowing there's a tiny traveler stowed away under his swampy ballsack, squirming around in disgust.
You're always included when he decides to jerk off. The first few times, he comes up with a barely-thought-out roleplay session that always ends in your defeat, teabagged under his giant foalmakers or ground against his meaty shaft until he cums. After the fourth or fifth time (You've lost count) he gets even lazier and just wanks on top of you.
Despite how humiliating it is, you almost look forward to it. It's one of the few times you get fresh air. And when he's done, you're given a meager amount of water and junk food as a reward before you're shoved right back in that filthy pair of underwear.
You're never more than a few feet away from his shaft at all times. Not even sleep can save you. He makes sure to keep you tied up close to his length. By the time the weekend is over, you absolutely stink of horse cock.
When you wake, you find yourself staring at a giant cage built for a rat. The horse whose cock had been your roommate for the past few days look down at you with a grin. He's been rubbing you against his thick length the entire time, even while you were unconscious.
"Surprise!" He says gleefully. "Welcome to your new home~. Well... a second home, I guess. This is where you'll be staying while your master is gone."
You shudder. It's mostly empty. You see a few used socks and underwear that make for your 'bedding', as well as a bottle with a straw on the end. The last thing you see is an empty bowl. It's a stark contrast from the nice, albeit filthy, bedroom the horse sleeps in.
You close your eyes, trying not to focus on the pleasured whinnies of your captor. Part of you still holds out that this is some twisted nightmare, but you've never had one as horrible as this. The feeling of the warm, pulsing cock underneath you is too real to deny. You can feel his balls draining as he neighs in bliss. Even after countless orgasms, your presence still gets him off.
Once he's finished, he makes sure to give you one final 'kiss' from the snake, smearing your face with what thick cum is left on the tip before tossing you in the cage.
"Be back in a few hours, pet. Make yourself comfortable while I'm gone~."
With that, he casually walks off, closing the door behind him.
You shudder, standing on your feet. It's the first time in days that you've been alone, but you're still trapped. The cage is made of steel, and the only way out is locked. You bang against the bars, desperate to somehow get free, but there's no way out.
Even while he's gone, his scent lingers, both on the underwear that is your bed and on you. It's a part of you forever, marking you as his.
Your stomach growls. You reflexively lick the seed on your face. It's thick, creamy, and salty... you're disgusted with yourself, but it's still good, and you're so hungry. Did...did he forget to feed you? He usually does after you've...pleasured him.
You look over at the bowl and realize where all that horse cum went. You get as far away from his underwear and the bowl as you can, but your stomach rumbles in desperation...
Outside the horse lets out a satisfied sigh. He's going to miss his cock pet while he's gone, but he can't risk anyone finding out about you. The cage is strong enough to keep you from getting out, though, and you have plenty of delicious food he generously donated to you.
He's going to be daydreaming of you all day. He'll probably tire himself out running back home, but he's got a perfect new sweatrag to dry himself off with.
As he closes the door to his apartment, he wonders to himself how long that pathetic resistance of yours will last. He knows he'll have you kissing his cock back eventually. The question was how long it would take.
Oh well. There's no rush. You're going to last a long, long time. He'll make sure to take good care of you for the decades to come.
