Prologue — Another Peaceful Day in the Mental Defense Professor's Office
It was a drowsy afternoon bathed in warm sunlight. Having finished lunch and wrapped up my lectures for the day, the urge to surrender to the creeping drowsiness was almost irresistible. Just closing my eyes for a few minutes promised the sweetest of naps.
With the new semester underway, a vibrant energy pulsed across the university campus. Freshmen gathered in lively clusters, arranging lunch dates with their upperclassmen, while even the seniors indulged in basking beneath the sun for the first time in a long while. Yet on such a pleasant day, I had a visitor in my office.
At the light rap of knuckles on the door, I rose from my chair and turned the handle. A cascade of shimmering pink hair immediately sprang into view. Hardly an unwelcome guest—in fact, she was the very visitor I had been looking forward to.
"I'm here, Professor!"
"Yes, it couldn't be anyone else, Miss Dohwa. Come on in."
"Hehe! You're finally returning my greetings properly, Professor! Guess being persistent really pays off!"
"If I ignored your greetings, I'd dread tomorrow twice as much. Besides, exchanging pleasantries costs me nothing..."
"Tee-hee, exactly! Just saying hi to each other makes the whole day feel so much better!"
"Let's go with that. Do you have enough time today?"
Knowing she would come, I set out the tea and biscuits I had prepared in advance. Her eyes sparkled at the sight, and she raised a hand eagerly.
"Yep! I specifically talked to my agency and cleared my schedule before coming. There's nothing after this. Complete freedom!"
"That's a relief. Didn't you say you were cutting it so close last time that you nearly ended up late?"
"Ugh, well... that was because I forgot to tell them in advance, you could say..."
The pink-haired girl twiddled her fingers sheepishly—Cha Dohwa. At a glance, she seemed like nothing more than an adorable college student, but she was actually an active idol and a dedicated superhero. I had heard she even spent whatever free time she had on weekends doing volunteer work. She lived in an entirely different dimension from an indoor homebody like me, who preferred to spend weekends doing absolutely nothing at home.
"A-Anyway, today is totally fine! We can take all the time we need!"
"Is that so? Good to hear. I felt a bit guilty about wrapping things up so hastily last time, wondering if you were all right."
"Aw, don't worry about that at all! You're going out of your way to make time for me, Professor. I'm just grateful that you're helping me like this."
Watching her giggle so brightly, it was easy to see why she had such a massive following. Come to think of it, didn't someone mention there was even a fan club for her here on campus?
"As expected, you truly are cut out to be a hero, Miss Dohwa. Well then, shall we have some tea before we begin?"
"Yep...!"
I picked up my cup as Dohwa delicately sipped her tea and nibbled on the snacks. The premium tea leaves yielded an exquisite aroma. It had a way of easing the drinker's mind, so to speak—soothing taut muscles and dissolving physical exhaustion with every swallow. Dohwa knew this well, which was why she made a point of enjoying a cup whenever she visited my office.
"Phew..."
"How is it? To your liking?"
"Yes! If I had my way, I'd drink this every single day..."
"Haha, I don't have that much of it myself. Still, if you keep working hard in my class, I wouldn't mind giving you some as a reward."
"Gasp! But I'm already trying so hard! Just how much more do I have to do, Professor?!"
"I'm joking, just joking. I know better than anyone how busy you are juggling idol work and hero duties. I'll pack some for you before you leave, so take it with you."
"Ah...! Thank you so much!"
Seeing her beam and bow her head in gratitude brought a natural smile to my face. A pretty girl really did look charming no matter what she did.
"Now then, Miss Dohwa. Shall we move on to our lesson?"
"Yep, I'm ready!"
Ting—
The moment the teaspoon lightly tapped the rim of the teacup, a resonant chime rang out, and Dohwa's gaze grew unfocused and hazy. Proof that my power was working like a charm.
"Did you finish the homework I assigned last week?"
"Yes, Professor... Thanks to your instructions..."
"Then I can grade today's assignment, correct?"
"Yes... Of course..."
"Then, Miss Dohwa, would you mind showing me your work?"
Nodding submissively, Dohwa slowly rose to her feet.
Rustle, rustle, slide—
Accompanied by the soft friction of fabric, the voluptuous body hidden beneath her oversized hoodie revealed itself to the world. Should I expect anything less from an active idol? Her impeccably maintained, firm physique was an absolute marvel. Perky, full breasts that defied gravity; vivid, pristine pink areolas and erect nipples. Though I had yet to lay a finger on her, she was already dripping wet. The slick moisture drenched not just her womanhood but ran down her inner thighs, pasting wisps of pubic hair against her glistening skin.
"You trimmed down there? It looks much neater and very lovely."
"Last time... I was so busy... I'm sorry..."
"Not at all. In fact, seeing you completely raw and untamed was wonderful in its own right. It happened to be quite to my taste, actually. By the way..."
With a casual beckon of my hand, Dohwa squirmed and hitched her clothes higher, holding them up so her luscious breasts were on full display. Her skirt, already half-unfastened, had slid down to cling barely around her thighs; had her frame been any slighter, it would have tumbled all the way to her ankles.
Outside of work, she deliberately wore loose-fitting clothing to avoid drawing eyes, seeking comfort on her days off after spending so much time squeezed into form-fitting idol stage outfits. That very contrast only made her look infinitely more depraved right now.
"You're already soaking wet. Were you looking forward to having your assignment graded today?"
"Hngh...♡ Th-That's..."
"It's fine. It's just the two of us in this room. Let's take our time grading your homework, Miss Dohwa."
"Y-Yeheees..."
I stood up and stepped closer. Dohwa swallowed hard, her petite lips parting and fidgeting in desperate anticipation. Reaching out, I caressed her soft cheek before slipping a finger past her lips. Without the slightest hesitation, she parted her mouth, took it inside, and began sucking avidly.
"Haaah...♡ Slurp, chup...♡ P-Professor..."
Cha Dohwa was so famous that anyone who heard her name would immediately go, Ah, that idol? She was both a top celebrity and a reigning superhero. Countless fans adored and cheered for the woman before me with burning passion, yet the most intimate, sacred parts of her that none of them would ever see were laid bare before me, completely defenseless. No, calling it merely defenseless didn't do it justice—she was eagerly offering herself up for my viewing pleasure.
"Now then, why don't you come over here?"
"Y-Yes..."
Slowly, carefully shuffling her feet so the skirt hitched around her thighs wouldn't drop entirely, Dohwa came closer. I placed my palm against her lower abdomen.
"Hnngh, ah, nghhh...♡"
"How many times did you masturbate?"
"F-Five times. I tried to do it every day, but... there was so much work...♡"
Rather than pressing firmly, I gently grazed and caressed her lower stomach. Dohwa trembled at the light touch, biting her lip softly.
"Do you want to come? You remember our promise not to hold back, right?"
"B-But...! I-I'm an idol... and a hero! How could I, right in front of my professor...!"
"No, Miss Dohwa. Holding it in is bad for your health. Besides, this is all part of grading your homework, so there is nothing to feel ashamed of."
"Is that... so? Huh? I'm... not ashamed...?"
"Of course not. This assignment was designed to see how honest you've become with your own feelings and desires."
Cha Dohwa was thrown into confusion as her ingrained common sense clashed against the hypnosis I had implanted. Yet I had zero worry that the spell would break. For one, the hypnosis I wove was hardly fragile enough to unravel over something like that.
"Th-Then can I really... come? My tummy feels so hot right now... Is it really okay to come? I'm really going to, okay?!"
"Yes, Miss Dohwa. Just let yourself go. Only then can I properly assess what level you're currently at."
"Hnk, ngh...! Ah, haah...♡"
And secondly, the primal desires she had repressed while serving as both an idol and a superhero were vastly more potent than I had ever anticipated.
"I-I'm coming...♡ Coming, coming, coming, I'm comingggg ♡♡♡ Nghh...♡"
With a wet gush, Dohwa squirted heavily, her knees buckling as climax tore through her. I caught her swaying body and guided her gently onto the sofa.
"Hmm... is this her limit for now? Taking it step by step makes the progress a bit slow."
"Heh, ahh... hah, ngh... fuuuh...♡"
"Ah, but the afterglow lasts longer? It certainly seems much more drawn out than last time. If I make good use of this..."
Watching Dohwa lie limp on the cushions, drained of all strength and gasping in shallow breaths after her orgasm, I tallied today's harvest in my head.
"Alright. That will do for today, especially if we need time to clean up. Now then..."
Snap!
"Huh? W-What...? Professor?"
"You're awake, Miss Dohwa."
"Gasp! Don't tell me I fell asleep?! I-I'm so sorry...!"
"Don't worry about it. You were sleeping so soundly that I could tell just by looking how exhausted you must have been."
"Ugh... and here I made sure to go to bed early last night..."
"That only proves just how much mental and physical fatigue you've accumulated. Oh, and your grade for this homework assignment is a C-plus. You still weren't completely honest with your own heart."
"Ah... You already graded it?"
"I finished it quickly while you were resting. Still, seeing how earnestly you follow along makes teaching truly worthwhile and rewarding, so don't let it get you down too much."
"...Thank you, Professor. Someday, I will definitely repay this debt of gratitude! Oh, and when we hold our next concert, I'll make sure to get you a ticket!"
"You really don't have to go that far..."
"I want to, because I'm just that grateful!"
Fresh and pristine as when she had first arrived, Dohwa stood up and bowed politely.
"Well then, I'll see you next week!"
"Get home safely. And don't forget to do the homework I assigned whenever you find the time."
"Yep! Goodbye, Professor!"
Listening to the electronic chime of the door locking behind her, I leaned back against my chair.
"Phew... What a fantastic job this is, honestly."
I lightly tapped the nameplate engraved with my name.
For some reason, the office chair felt especially plush and comfortable today.
