Spanking Slave
If there was one miscalculation on my part, it was underestimating Sena far too much.
I sat the naked Sena down and presented her with a set of tough magic-related problems. For every one she got wrong, she'd take that many hits. It was a forced role-play scenario to heighten the meaning of the punishment and help me immerse myself fully.
But then, "Isn't a perfect score too much?"
Sena was the strongest among the students, the type with vast knowledge. Even these were the hardest ones I'd cherry-picked, yet she nailed a perfect score like it was nothing, as if questioning why I'd even call them problems.
"Too easy."
"This isn't fun if you don't want to get hit. At least pretend to mess up a few."
"I can't lie about what I know. Why would I get it wrong on purpose?"
Damn it. Our fundamental sense of common sense was completely mismatched. No matter how badly she wanted to be spanked, someone like Sena needed to speak the truth to feel satisfied. So what now?
She shot me a sideways glance like she was gauging my reaction, staring blankly without a hint of shame, not even covering her naked body. Her breasts and nipples were on full display atop the desk. Just looking made me swallow hard.
"Looks like we'll have to add some restrictions, then."
"Give it a shot."
"But let's make a promise first." I stuck out my pinky and prepared my thumb. Old-school, sure, but a pinky swear carried weight.
"No matter what I do to you, you won't dodge or complain afterward."
"Sounds fun. Let's try it."
Fun, huh? Yeah, it'll be fun, alright. But as Sena eyed my extended finger curiously, she suddenly asked, "What's that hand sign for?"
Oh, right. This world probably didn't have pinky swears. I kept forgetting the cultural gaps between my world and this one sometimes.
"It's a pinky promise. One you absolutely have to keep."
I demonstrated, and Sena awkwardly mimicked me like a kid learning something new. "And?"
"Hook your pinky with mine."
She fumbled a bit until I guided her, then got it right away. "Then press our thumbs together."
"What kind of magic is this?"
"Not magic. But we have to keep it with our conscience, like magic. It's like a vow from my world. Never break it."
It was a bit grandiose for a mere pinky swear, but that's how I'd sell it to convince her. Sure enough, Sena's expression turned serious as she accepted it.
"A vow from your world. Got it."
"Pinky promise."
"Pinky. Promise."
Perfect. Now for round two. I handed her the same problem set. She raised an eyebrow since she'd already aced it, but she tackled it without complaint. I placed an hourglass in front of her.
"Ten-minute hourglass."
It was sized for maybe three minutes normally, but magic slowed the sand's fall.
"Ten minutes is short."
"Even for problems you've already solved?"
"Nah. I can do it."
Confident as ever, I watched her work, then made my move. I slipped my hand under her armpit and grabbed her breast.
"Ah!"
Sena jolted, her body trembling as she turned to look. But realizing the game, she refocused on the paper.
I kneaded her perfectly sized breasts like dough, squeezing and massaging. Young and firm, they pushed back against my fingers, sometimes slipping out of my grip. For the record, don't mash them like you're trying to deform them—that's amateur crap from cartoons. Breasts aren't tough slabs of meat; they're sensitive and will hurt if you go too rough.
"Ngh."
Sena endured my touch with faint moans but kept solving quickly. Yeah, it took more than that to break her stubbornness.
Time for phase two. "Kgh!"
I raked my five fingers up her breast like tickling. You have to stroke it that way to focus the nerves and amp up sensitivity. It worked—her quill paused, her head dipping slightly.
"Ugh...."
I kept teasing around her nipple without grabbing it, building frustration with repeated strokes. I love making obedient girls squirm when they follow orders to the letter. Sure, it's fun at first, but without some 'trial,' future play gets boring. I'm the type who thrives on challenge.
As my fingers traced her areola, hot breaths escaped her lips. "Hah... hngh...."
She twisted and shrank away, but I followed, stimulating relentlessly.
"Ngh... why won't you just...."
Over-sensitized, she muttered a complaint before stuffing it back down. Impressive woman—still grinding through the problems like this.
To reward her grit, I upped the ante. Shhh, fingers gliding over skin toward her nipple. Teasing proximity made her quill freeze. She was waiting. I hovered, hesitating... then ping. A light flick.
Electricity shot through her nipple as her body bucked. "Hnnngh...!"
After priming with sensitivity, hit with a big stimulus. But not enough. Ticka-ticka. Rapid flicks, and her head burrowed toward the desk, shrinking. I pursued without mercy.
"Ah! Hng.... Ngh!"
Cute moans I'd never heard from her before. Hearing them up close, blood rushed south for me too.
Ticka-ticka. Treating her nipple like a toy, but she twisted to evade. Annoying. I propped her side with my elbow, pulling her back against my chest.
Leaning on me, she gripped the quill stubbornly, but her elbow clenched, body quivering. Squeeze. No warning—I pinched hard. Her squeezed-shut eyes flew open.
"A-ahh!"
Her head snapped back onto my shoulder. Our eyes met. Flushed face, glaring daggers... but those teary eyes. Only I got to see the ice witch so defenseless.
"You...."
I gently tugged the pinched nipple upward. Her breast lifted like a toy. Lips pursed tight, she didn't complain even as I toyed with it, quill still moving.
Still not giving up? Fine, escalate. I brought my mouth to her neck, burying my face. Reflexively, she shrank away, trying to push my head with hers.
"I-it tickles...."
That's the point. Her neck smelled divine—something I'd never tire of inhaling all day.
"Ah... aah...."
I tickled, pinched, flicked her neck and breasts relentlessly. Education became secondary; tormenting Sena was pure fun now. I played with her like she was truly mine.
"Haa... haa... hngh... nghh!"
My hands grew bolder, lips kissing, sucking, licking her nape without care for marks.
Should I kiss her? The mood was right; it'd probably slide. Bliss with this beauty, and a kiss? I'd feel like I owned the world. I angled for an opening, but clink.
Cruelly, the hourglass flipped, starting another ten minutes. Time up. Regretfully, I pulled back. Sena's face was utterly melted—flushed cheeks, dazed eyes, teary rims, mouth agape with hot breaths.
After a few more nipple tweaks, I whispered in her ear. "How's that feel?" Smirking, I teased mercilessly. "A brilliant witch who could ace these problems blindfolded, and look at you—half-done and already a mess."
"Haa...."
"Does the noble, icy witch really get this undone by a mere servant's hands? Standing there with your slutty nipples all perked up!"
Squeeze. She shuddered violently. Lips pressed, glaring—but even that was adorable.
"Pathetic. So firm and strong in front of others, but drooling and tearing up for your own servant. What would the other witches think?"
"You...."
"On the bed, face down."
No time for rebuttals. I hauled her up and shoved her onto the bed, draped over the edge. She quickly hugged a pillow tight.
"Twenty unsolved. More than I expected."
"......"
"So, how many spanks?"
"...Twenty."
No cane. I wanted to wreck this ass with my bare hand. Before starting, I kneaded her cheeks.
"How's it feel getting your ass spanked like a naughty kid by your servant?"
"......"
"It'll burn hot...."
I stroked her pussy. She trembled, legs clenching.
"Soaking like this means you're looking forward to it, right?"
Her sticky juices coated my hand. I smeared them across her ass.
"Be honest between us."
"...About what?"
"You don't really care about getting stronger, do you?" Grinning, I spread the slickness like lotion. "You just want your ass spanked."
"...No."
"How was your first spanking?"
"......"
"Felt good, right? All itchy and hot down here." I smack-smacked her dripping slit, making lewd sounds. She twitched with each wet chap-chap.
Instant reactions to every touch—endlessly entertaining. "Does anyone know the fearsome ice witch is a masochist who orgasms from ass spankings?"
"S-stop teasing...."
"Say it yourself."
I shoved her cheeks side to side like a pinball. " 'I'm not interested in magic growth. I'm a perverted maso who gets off on ass spankings.' Repeat after me."
"......"
I'd ordered it on a whim, but no way she'd swallow her pride....
"I'm...."
...Huh?
"...not interested in magic growth."
...She's actually doing it?
"I'm a perverted maso bitch who gets excited from ass spankings."
Now I was flustered, blinking at her. But Sena, deep in the role, arched her ass up.
"Happy now? Hurry up and spank my ass already."
