His Human Subject

by Stella Rising

He retrieves a small black crop from a cabinet next to the bed. “Liar. If you were, you wouldn’t react to pain you didn’t actually feel. So, that’s your goal today: clear your mind. The only thing that exists for you right now is your physical form and the discipline it’s receiving. Am I clear, pet?”

  “Yes, sir.”

  “Good.”

  I do as he says, as best I can. My mind wants to race, and it’s hard to summon my reserve of willpower during a spanking.

  He wields the crop with expert precision, seemingly smacking a different part of my ass each time. My skin feels painted, one hard square of nerves at a time. I force myself not to think about my humiliation or even the Piskites. For a while, it’s just me, Prust, and the many sensations overtaking my body. My pussy quakes, desperate for relief—I’d rather not dwell on it, but if I’m being true to my mindfulness, I have to acknowledge the desire.

  I stare back at Prust until my neck aches. His manner mesmerizes me; it’s like watching a master painter in front of a canvas, only the canvas is me. After a while, he notices I’m watching, and his expression darkens.

  “Didn’t I tell you to look at the planet?” he asks.

  “Yes, but—”

  He waves off my objection. “You don’t think you can be present, and follow a lesson at the same time? You sell yourself short, Alexis.”

  Whimpering, I watch as he puts away the crop and takes out some kind of curved piece of chrome. Thick as my thumb, it features a small ring at the straight end.

  “Do you know what this is?”

  I shake my head.

  “This will ensure your attention goes where it’s supposed to.”

  When I look at the device again, it glistens with oil, in the process of self-lubricating.

  “Wait, what’s it for?”

  Prust grins and slides the toy between my ass cheeks, spreading the fluid all around.

  “Are you serious?” I cry, squirming in my bonds, trying to keep the toy away.

  “As an extinction-level event,” he replies, pressing the toy into my tight hole.

  I gasp as the strange pressure invades my mind. Though it hadn’t looked particularly large, it feels considerably bigger poking against my rear. Though the bizarre penetration brings a pain I’ve never experienced, it’s not without an illicit pleasure. Prust urges the toy in deep, driving it hard against my tight muscles, then leaves it in place. At first I don’t understand how that’s supposed to help me focus on the planet, then I see he’s not finished. He retrieves a length of rubbery silver cord and proceeds to thread it through the ring at the end of my hook. Then he gathers my hair in his fist, draws my head back, and knots the cord around my bunched locks.

  “Holy shit, are you kidding me?” I shout, overwhelmed by my predicament. Any movement of my head translates into sensation in my ass. If Prust were to leave me this way, there’d be nothing I could do to escape. My neck starts to ache almost immediately. I try to clench and force the hook out, but it’s impossible. The toy refuses to budge. My head pounds, sweat rising, as reality sets in: this is going to get extremely uncomfortable very rapidly. “Please, Prust! I’ll do what you want, just untie me!”

  He shakes his head. “Focus this time, Alexis. I’m not letting you go until you’ve learned your lesson.”

  “Please,” I whimper, the hook shifting inside me. “I promise I will.”

  Prust smiles, patting my ass. “I know you will.”

  Oh, fuck.

  This is too much. It’s bad enough to have a toy in my ass for the first time—being fully restrained at the same time, unable to avoid the new sensations, sends my mind reeling. Maybe I could handle it better if Prust wasn’t so clearly enjoying my suffering.

  He steps behind me, and now I can’t turn back to him without pulling on the hook. Hearing a rustling sound, followed by a soft thump, my eyes widen—it sounds like clothes being stripped off. My pussy clenches, eager for attention—anything to get my attention off the hook. My fluids drip, yearning for Prust’s monster cock.

  I moan as he plunges inside, not realizing how incredible it would feel as his thick shaft presses against the hook from within. He takes his time inserting himself fully, drawing out and pressing back in with infuriating deliberateness. I’d complain, but I probably wouldn’t like the consequences. I’m at Prust’s mercy, and all I can do is try to earn my reward. At least I can be assured that between his incredible anatomy and unflagging stamina, he won’t disappoint.

  “Are you thinking about the planet?” he asks, pausing his motion.

  “Yes, sir,” I lie.

  A jolt of heat stings inside my ass—an electric shock! I wail, thrashing in place, desperate to remove the toy and soothe my ass, but I can’t.

  “What was that?” I cry, my body quaking.

  “Dishonesty is unacceptable,” Prust growls, pulling on the hook. “You better fix your behavior, pet, or you’ll find out what else this device can do.”

  Tears stream down my cheeks. “Fuck you, let me go!”

  The toy releases another shock, causing me to instinctively clench down hard. Prust grunts with pleasure as my walls grip his cock, then reaches to my face and brushes my hair from my eyes.

  “We could do this all day, Alexis. Is that what you want?”

  “No, sir,” I whimper.

  “Apologize for lying,” he orders, drawing the hook in and out while turning it back and forth, massaging my soreness from the inside.

  “I’m sorry, sir!” I shout. There’s not much I wouldn’t say right now to get him to stop.

  “Good. Are you going to lie again?”

  “No, sir,” I mumble, clenching down again on his cock and the hook, ravenous for pleasure to erase the pain from my consciousness.

  “That feels so good, Alexis. Does my tight little human like being fully stuffed?” he asks, jostling the hook some more.

  “Yes, sir,” I mumble, shame boiling in my blood.

  “Have you ever had your ass used before, pet?”

  “No, sir.” As if that wasn’t obvious to him.

  “Lucky me,” he chuckles, slowly thrusting.

  Waves of bliss cascade through every cell in my body, and I forget all the pain of getting spanked and shocked—I forget about my abject humiliation. Prust’s cock feels too good.

  “You want to come, pet?” he asks, slowing down enough to make me squeal.

  “Yes, so bad!”

  Prust slaps my ass. “Say you like being stuffed by your master.”

  Closing my eyes, I shake my head, accidentally pulling on the hook. “Oh... please...” I beg.

  He gives my backside another smack with each word: “Do. You. Want. To. Come?”

  Sweat drips down my forehead. I clench down hard on his cock, but Prust quickly pulls out.

  “Last chance, Alexis. I can come back later. Maybe give you an hour to reflect on your situation.”

  “No, please! I like being stuffed by my master,” I say.

  He tugs sharply at the hook, making me howl loud enough to fill the ship.

  “Convince me, pet,” he growls.

  “I like... being stuffed... by my master!” I scream.

  Prust plunges back in, but he doesn’t let go of the hook. “Once more.”

  “I like being stuffed by my master!” I shout.

  “You need your alien master’s big cock,” he says, resuming his thrusting.

  “I need my alien master’s big cock!” I cry. Right now I’d probably say anything for him to pound me harder and faster.

  Prust laughs, giving me what I crave. “Eyes on the planet, pet,” he says.

  I don’t have much choice in that, but right now he’s all I can think about. Not Piskiron, not the colony—not my smoldering ass—just his cock and the ecstasy he’s creating inside me. When I climax, I let out an earsplitting scream, catapulted into a trance of pure bliss. On the fringes of my perception I can feel Prust hammering me wildly and spanking my ass, but I’m too overwhelmed t
o compartmentalize what I’m experiencing.

  “Keep coming,” he whispers into my ear. “You’re not to stop until I tell you.”

  I’d say that’s not going to be a problem if I could speak. My jaw hangs open, but all I can do is breathe, my lungs desperate for oxygen.

  Drawing from his endless reserve of energy, Prust thrusts into me until I peak three more times. Yet, he still hasn’t come. Without a word, he unties the cord tying the hook to my hair, releasing my neck. I’d stopped feeling how much it hurt until now, and the flood of sensation breaks me out of my rapture.

  “What do you say, pet?”

  Does he seriously expect me to thank him?

  “Prust, why are you doing this?” I ask in reply, rolling my neck around my shoulders, trying to soothe the ache. “Because I’m not... sad enough about... some ancient aliens?”

  “In part,” he says, slipping the hook out of my ass. “But mostly for lying, and for being disrespectful.”

  I grunt in relief, glad to be rid of the hook, though my respite doesn’t last long.as Prust immediately starts driving his cock into my tight back entrance. Crying out, I press my head into his bed. The hook hadn’t been very thick compared to his cock, and his shaft spreads my flesh even wider.

  “I’m sorry!” I shout, alarmed by the massive new intrusion inside me.

  “For what?”

  “All... of it!” I gasp, trembling as I feel him sink in deeper.

  “Good, Alexis. Think of that until I say otherwise.”

  I’m still extremely sore from the shocks, but at least he’s going slowly, giving me time to adapt to the incredible girth attempting to penetrate my tender bud. He goes deeper an inch at a time, pulling in and out, working his cock gently onward. My body quivers, enthralled by the pain and pleasure. Prust shows incredible patience, but also determination, as he doesn’t stop until he’s driven in all the way.

  Moaning uncontrollably, I writhe in my bonds as Prust’s piston-like motion drives me to new heights of ecstasy. Mortified by such a dirty, submissive act, my face glows like a neon sign. And yet, I don’t want him to ever stop. I try to keep my mind on my contrition, but before long I’m well past the point of conscious thought.

  Building momentum, he grunts from his own pleasure, his musky, masculine aroma surrounding us.

  “Your ass is perfect, Alexis,” he says, slapping it as he pounds faster.

  I think I mumble my thanks, but I can’t say if it comes out as words or just another wail. My whole body bucks as the telerings release me, and Prust holds me tight to his muscular frame. He pounds my ass like a machine, then groans euphorically, releasing his seed.

  He lies down, keeping me wrapped in his arms. All I can do is breathe, lost in subspace for what feels like hours. Lying against his body, letting him stroke my hair, my mind is finally clear. All thoughts have been driven away.

  “Did you like that?” Prust asks after a while. He strokes my hair and cups my chest.

  “Yes, sir,” I admit, gazing out the window into space.

  “Good. And did you learn an important lesson?”

  “Yes,” I reply, wincing from the soreness in my backside.

  Prust picks me up and turns me over so I can face him. “I think we should make your tutelage more frequent,” he says.

  Tutelage.

  Yeah, I think I can call it that and not feel too cheeky.

  “How often?” I ask.

  Prust grins. “Daily. You have much to learn.”

  “You’re crazy.”

  “I wasn’t asking, Alexis. If you want my help, you’ll do as I say.”

  I bite my lip. If I told Dani that I met an incredible lover and was having the best sex of my life, she’d tell me not to let something like that go to waste—unless the lover turned out to be a Dominar. What would she think if she knew? What would everyone think?

  “It can’t get out to anyone else.”

  Prust sighs. “We can try and keep it a secret—I will not say a word—but the truth has a way of getting out eventually.”

  “People have their own business to mind. It’ll be fine.”

  “Don’t you bunk with your friend?” he asks. “Won’t she ask where you’ve been tonight?”

  Dani? If she’s lucky, she’s had half as much fun with Kentucky Ken as I’ve had with Prust, and she won’t be back until morning. But what if I’m unlucky, and she’s in our tent, waiting to ambush me with uncomfortable questions? I hate lying to anyone, least of all my best friend. Could I be honest with her? Would she accept the truth? She must know that getting intimate with a Dominar was never one of my illicit fantasies, and that this happened more by accident than anything else—but what if she doesn’t care?

  I can’t tell her. Not yet, anyway.

  Sighing, I pull up my panties. “I’ll think up some good excuses.”

  I’ll need a lot of them.

  Chapter Eleven

  Explaining my extended absences proves harder than I imagined. During the day, people expect me to be easy to find—I’m the leader of the colony, after all. At night, well... there are only so many reasons for one not to be asleep in her tent. Still, Prust and I find ways. I become pretty good at eating an entire lunch along the walk to his residence.

  “I just need to clear my head,” I say to anyone asking where I’m going. It’s my go-to refrain. I tell myself it’s not a lie. Powerful orgasms always turn my brain to mush. Like some kind of conditioned, Pavlovian response, my pussy warms with every step I take toward Prust’s residence. By the time I see the dome, my panties are usually soaked.

  Today I’m a little early, having just finished picking the ripened cherry tomatoes from my garden. Bringing a bowl of them with me, I congratulate myself on coming up with a neighborly gesture as a reason for today’s visit.

  The door opens to admit me automatically, though Prust isn’t here. This isn’t the first time, so I set the tomatoes down on the kitchen counter. Then I head over to the living area table and bend over, laying down on my chest. Feet planted flat on the floor, I cross my arms behind my back and hold the position. I will stay like this for as long as I can, practicing patience. If Prust is busy, I’ll leave and try another time, but I bet he’ll be here. He doesn’t want to miss our daily tutelage either.

  Sure enough, I only have to wait a few minutes.

  “Alexis,” he says, striding toward me. “Look at you, so willing and ready.”

  “Yes, sir,” I reply, my cheeks flushing. “Is that okay?”

  He chuckles. “It won’t earn you any extra credit, but yes, it’s okay.” He opens up his cabinet of devices and toys and picks out a black butt plug I’ve grown familiar with throughout the past few days. Thick, long, and plenty hard, the toy features a flared base and a self-lubrication system. Each time I look at it I could swear it’s somehow gotten bigger. Knowing Dominar tech, perhaps it has.

  Prust drags the plug between my ass cheeks, spreading the oil all around. I’ve gotten better at relaxing my tight ring of muscle, allowing plugs in with less and less effort. This time it eases in without too much pressure, but I still gasp and twitch as the toy’s widest section penetrates fully.

  “Very good, pet,” he says.

  “Thank you, sir.”

  “You’ve grown to enjoy the way this feels, haven’t you?”

  “Yes, sir,” I admit, blushing. There was a time where I would have slapped him for asking such a question, and either refused to answer or lied. The truth may still embarrass me, but at least I’ve learned not to hide it. Thankfully, Prust doesn’t judge.

  “Good.”

  Pulling the device out a little and letting it sink back in, Prust enjoys my squirming for a time, warming us both up for what’s to come. When I glance back, I see a familiar bulge in his pants.

  Then he turns, his expression shifting suddenly. He pulls my pants up quickly. “Take a seat,” he says, pointing to the living area.

  “What’s going on?” I ask, obeying h
is command, though I’m totally confused. Sitting on the plug makes me grimace, but it’s not the first time I’ve done so.

  A knock sounds from the entrance of his dome.

  Shit!

  I tell myself to stay cool; Prust and I are both fully dressed. I brought the tomatoes. This is just a social call, as far as anyone else is concerned.

  Prust opens the door. “Ms. Long, hello. How are you?”

  “Hi, Prust,” says Dani, slipping past him and inside the residence. “Alexis, what’s going on?”

  I try to keep my face passive, but I’m sure my best friend can read my alarm.

  “Did I interrupt something?” she asks as Prust takes a seat opposite me.

  “Not at all,” I reply steadily. “I just came to discuss some business with Prust.”

  Dani nods. “Like what?”

  “Bringing over a second wave of colonists,” I reply, not missing a beat. “I want to call up a vote on that within the next month.” It’s not a total lie: I have discussed the matter of bringing more people from Earth with Prust, once while getting dressed after a session. I did mean to bring it up again.

  She looks to Prust, who nods.

  “Oh.” Dani uncrosses her arms from her chest and brushes back her hair. “That’s neat.”

  “So what brings you here?” I ask her.

  “Me? I guess, well... I couldn’t find you anywhere, so I said, ‘what’s the least likely place she’d be?’ I thought I was being crazy, but here you are.”

  I fake a laugh. “It was so important, you had to come looking?”

  Dani sighs. “I know, just... this isn’t the first time you’ve been... scarce. Like, lately. I thought it was strange.”

  If only she knew the half of it.

  “Well, you’re not crazy,” I say. “Prust and I have been having some routine meetings.”

  “Routine? For colony business?” Dani asks, raising an eyebrow.

  I could complain about getting the third degree, but in her place I’d be doing the same thing. “Sometimes. He’s also teaching me a bit about the galaxy. Like, the other day I learned some of the history of this planet,” I explain, glad to be steering the conversation somewhat closer to the truth. Prust taught me plenty of other stuff too, but I’m leaving those parts out. “If we’re going to live here, we should know as much as we can, don’t you think?”
