The device was as thick as a log, with a horse-like neck attached to its body. Its legs were made of steel supports. The surface was covered in dark brown synthetic leather, emitting a dull, eerie glow.
"How do you use this?"
"For now, President, try straddling it."
"Eh, while naked?"
"Of course."
Kurasue-san obediently mounted the horse, and Kido-kun, as if it were routine work, restrained her wrists in the leather cuffs attached to the horse's head.
"President, if you struggle, you might fall and get hurt, so stay still, okay?"
"...U-uh huh."
He also cuffed her ankles. Now Kurasue-san was completely one with the horse.
"President, you look amazing. From behind, your ○○ko is completely visible."
"N-no... don't stare so much..."
"Your butt is cute, and your anus is pretty too."
"S-stop, it's embarrassing..."
Lick, lick lick, slurp.
"Kyaaah! W-wait, what are you licking!? That's dirty!"
"It's not dirty at all, President. I'll take good care of you, so relax."
"Nnngh!! S-stop it, I said!!"
Kido-kun's tongue work was skillful and precise. Using his hands and mouth to their fullest, he caressed Kurasue-san. I found myself transfixed by the sight of him meticulously licking even inside her vagina and anus. With each lewd, wet sound, a sensual moan escaped her lips. It was undeniable proof of how effective his cunnilingus was.
"Aah, ahn... there... yes, ahh, it feels so good, more, lick me more..."
Kurasue-san's face was filled with ecstasy. I'd never seen her make such an expression before.
I first met her about two and a half years ago, during homeroom after the entrance ceremony. At the time, having just been assigned my first class, I stood at the podium filled with both anticipation and anxiety. Most of the students were meeting each other for the first time, and the classroom was noisy and restless. Amidst this, Kurasue-san stood up smoothly and scolded the rowdy students, "Be quiet! You can't hear the teacher!" Her dignified and elegant voice instantly silenced the class, and everyone's attention turned to her. Even I couldn't hide my surprise. With just one stern word from her, the previously chaotic atmosphere came to an abrupt halt.
Since then, she had united everyone as the class representative and eventually became the student council president. She was excellent, serious, possessed strong leadership, and was beloved by all. As a teacher, I couldn't ask for a better student. In fact, as a first-time homeroom teacher, I owed her so much.
And now, this model student was bound to a horse, moaning and writhing. I was surprised at how intensely this situation aroused me, stirring up my sadistic urges.
Had I always been this sexually voracious...? But I wanted to see more—more of that honor student's face contorted in shame and pain, succumbing to pleasure...
"Kurasue-san. If you're only being teased down there, won't the top feel lonely?"
Holding her torso from below as she arched back from Kido-kun's cunnilingus, I pinched her two nipples.
"Hyahn! T-teacher, what are you...?"
Her body jerked from the sudden stimulation.
"See? We can't neglect this side either, can we?"
Squish, squish, squeeze, squeeze, squeeze.
"Aahh, no, I'm sensitive there, I'll go crazy—!"
She writhed, trying to shake off my hands. But with her wrists restrained, escape was impossible. The metal clasps of the leather cuffs merely rattled mercilessly.
"You're adorable, Kurasue-san."
Before I knew it, I was kissing her.
Mmph, slurp, lick, pant, smooch, slurp.
Kurasue-san didn't resist—instead, she actively pushed her tongue forward. Earlier, she had taken me by force, so I hadn't resisted, but now that I thought about it, this was my first time kissing another woman.
Lick, slurp, mmph, smooch, smooch.
That honor student was moving her tongue lewdly, like a prostitute. Excited by the situation, I responded by tangling my tongue with hers even more fiercely.
Slurp, mmph, smooch, suck, pant, pant, pant.
We exchanged saliva, swallowing each other's. The intense deep kiss left no room to breathe. It felt so good my head grew fuzzy, and I nearly lost consciousness. She must have felt the same. The look in her eyes, drowned in pleasure, made it clear her rationality had completely vanished.
"President, sorry to interrupt your fun with the teacher, but can I go in now?"
"Uuun, put it in, Kiro-kun's peeenis is sooo tasty ♡"
"Here I go!"
Squelch!
"Aaaaah!!"
Kido-kun began moving his hips slowly. She buried her face in the horse's neck, desperately enduring the approaching pleasure. If she didn't, what little consciousness she had left would surely vanish. I was no longer reflected in Kurasue-san's eyes. Good—then this time, I'll do this!
"Aahh, hot! It's hot! So hoooot!!"
"Teacher, what are you doing all of a sudden!?"
Left out of the fun, I lit a candle and dripped wax onto Kurasue-san's butt.
"I thought we might as well try this too. How is it, Kurasue-san? Remember the taste of the wax you dripped on me earlier?"
"Aah, it's hot! Teacher, stop!"
"It's hot, isn't it? But you did the same to me, so we're even now."
"S-sorry, I'm sorry, Teacher, I got carried earlier..."
"Oh, no need to apologize. The teacher will make a flower garden on your back too."
"Hyii, hyaaah—!!"
Ignoring her convulsions, I dripped wax evenly from her shoulders down to her butt. Soon, a beautiful array of roses bloomed across her back.
"Fufufu, I made pretty flowers bloom for you, Kurasue-san."
"Hahii, hahii, aauu..."
"T-teacher, please stop. Every time you drip wax, the President tightens around me, and even though it's only the fourth time, I'm about to—"
"Got it. I'll stop with the candle and try this next."
"W-wait, why do you have that...?"
"It was hanging on the wall. Since it's school equipment, it's fine to use, right?"
I swung the rose whip down onto Kurasue-san's back.
CRACK!!
The rose whip had multiple tips, making a loud sound without being too painful. But for Kurasue-san, whose sensitivity was at its peak, it must have been the ultimate stimulation.
"Aah, Teacher, it hurts, why... Stop..."
"This is your punishment. It's your fault for doing naughty things at school!"
"Hyukk, I-I'm sorry, forgive me..."
CRACK, SMACK, THWACK.
"Kyauun! Auh! Stop, please, ahn!"
"No, this is nowhere near enough."
"Haa, haa, haa, I-I'm sorry, I'm sorry, Teacher, I won't do naughty things at school again. Sumire is a bad girl! So, so punish me more!"
Just as I thought. Kurasue-san's true nature was the same as mine—a total masochist. Though she said no, her voice was sweet the whole time. Her rationality had been holding her back. That part was just like me. Fine, I'll smash through that wall you've built!!
CRACK!!
"Ugh!!"
Splurt splurt splooorch! Squirt! Sploosh! Splat!
"Huh? Kido-kun, did you just...?"
"W-well, every time the teacher teased her, the President tightened around me, and that last hit completely milked me dry..."
"Honestly, Kido-kun, how lame. We were just getting to the good part. Right, Teacher ♡"
"That's right. It seems Kido-kun needs some punishment next ♡"
"N-no way~"
What an unexpected surprise, but yesterday's breeding session was fulfilling. Kido-kun came three times each for me and Kurasue-san. He looked pale this morning, but I'm sure he'll be fine. He's a pro at breeding, after all.
Still, Kurasue-san. She looked so refreshed today. It seems all that pent-up sexual frustration was finally released. I had some doubts about Keyaki-san's suggestion, but in the end, it worked out.
"So, Kurasue-san. You must feel a lot better after yesterday, right? Now you won't do weird things with Kido-kun anymore?"
After school, I called her to the guidance room and asked again.
"Yes. I won't do weird things with Kido-kun at school anymore."
Good. One less worry for me. Hmm? Kurasue-san is clinging to me. What's wrong?
"So, Teacher..."
"What is it, Kurasue-san?"
"...Kiss me."
I am Tamada Monami, a teacher at Hanza High School. The past month's concern—Student Council President Kurasue Sumire's sexual urges—seemed resolved, but I can't shake the feeling that the problem has merely shifted direction. Ah, the next few months until she graduates fill me with unease.
