The Living Textbook
"Dress."
"Socks."
Vera dutifully scribbled down my words. So far, she was taking notes without a shred of suspicion. But what about this?
"Armpit-pussy."
"E-excuse me?"
"I said armpit-pussy. Do you need me to repeat it?"
"W-why would you attach that word to the end?"
"It’s not just 'that word,' it’s pussy. We agreed to be precise, didn't we? Besides, I’m the one who decides the terms. Hurry up and write it."
"Ah... right. Let's do that."
...By the time Vera finished writing down the twentieth word, her face was flushed so red it looked like it might burst.
"Alright, Teacher. Can I start memorizing now?"
"W-wait a minute. This is a bit..."
"We agreed to use the words I chose. You said it was a good idea..."
"You could just memorize them by looking at your own body, Edward."
"That wouldn't be very convenient for studying, would it? Not when I have such an excellent textbook right in front of me."
Vera’s eyes wavered. Before I regressed, she had always been calm and gentle, her eyes half-lidded. These days, I seemed to see her eyes wide open much more often.
"Ugh... fine. But turn around while I adjust my clothes. You aren't allowed to look, okay?"
"Can't I just watch?"
"N-no! Turn your head, quickly."
Even when I kept staring, she urged me to turn away. She’d shown me everything before; I didn't know what she had to be so shy about now. Still, I obediently turned around, and the sound of rustling fabric filled the room.
"...I'm ready."
It had only been a minute, though it felt like ten. Vera was standing there in nothing but her undergarments, radiating a heady, erotic scent, her arms crossed to cover her breasts. Her chest spilled over her arms, straining to be free. I could even see the pink areolas peeking out—what was the point of covering them with her arms? Just to hide the nipples at the tips?
"...This isn't what a teacher is supposed to be used for..."
"Right now, you’re not a teacher. You’re a textbook for effective study."
"What if Monica walks in while we're doing this..."
I had already locked the door. Even if it wasn't Monica, I didn't want anyone else seeing this sight but me.
"Are you satisfied now?"
"How did it come to this..."
"Hey now, textbooks don't talk back."
"A teacher is a living textbook, so it's fine. And if we're going to talk about that, what kind of student gets so... aroused during class?"
Ahem. Following Vera’s gaze, I realized my trousers were tenting significantly. I shoved my hand into my pants to adjust myself. I’d been so busy admiring Vera, I hadn't even noticed.
"Ahem. Shall we look at the clothes first?"
Vera’s discarded garments were neatly folded. This thin piece of fabric was...
"A dress?"
"The dress is the one next to it. That is lingerie. It’s worn instead of an undershirt. That over there is the stockings, slippers, and garter belt."
"Lingerie?"
"I added an extra word while I was undressing."
So this thin thing was lingerie. It looked incredibly... impressive. I loved stockings and garter belts, but lingerie seemed to be on a whole different level. It didn't look like it had much function as underwear... would it even cover anything properly? It was so sheer and fluttery that wearing it would probably be more lewd than being naked.
Did I make a mistake asking her to take it off?
"D-don't stare at it so intently."
"It looks like it’s completely see-through... are you trying to seduce me?"
No matter how I looked at it, it was a shame I hadn't seen Vera wearing the stockings, garter belt, and lingerie together. The image of black lace wrapping around pure-white Vera was... wow.
"It’s a cool material because it’s summer!"
Perhaps trying to forget her embarrassment, Vera began to explain earnestly. She couldn't hide her flushed face or trembling voice, but she always became serious when she was teaching. I could have pushed her further, but her serious expression was so pretty that I let it slide. Besides, I didn't think she’d last long anyway.
'Dress,' 'lingerie,' 'stockings,' 'slippers.' I memorized the four of them. The shirt hadn't been on the list.
"I've memorized these, Teacher."
"A-already? Then I suppose we have to move on to the next word..."
Realizing that the remaining words were all pinned to her own body, Vera’s movements stiffened. The serious Vera was already finished. I’d have to help her along for the sake of progress.
"Shall we start with your feet?"
"Eek!"
I gently sat Vera down on a chair and grabbed her smooth shins. Her feet were small, soft, and free of calluses, just like a child’s. Watching the elegant curve leading from her shins to her pretty, well-kept toenails, I thought for the first time that feet could be beautiful. I used to think anyone who wanted to bury their nose in a woman’s feet and lick them was insane, but looking at this, I felt like I could do it.
As I stealthily brought my nose to her foot, Vera shrieked and struggled to pull away. Every time her legs moved, the mound covered by her black panties flashed into view.
"W-why are you suddenly sniffing them?"
"Well, they say you should use all five senses when you study, don't they? Since I’m not very bright, I was trying to feel what a 'foot' is with my whole body."
"You certainly have a way with words..."
I didn't let go, pressing my nose back against her foot. She must have washed recently; her feet didn't smell like feet at all, but rather something fragrant. I didn't know what she’d used, but it was strangely stimulating—just smelling her made my cock feel even harder.
Twitch.
Every time my breath tickled her toes, Vera would flinch. I wanted to taste her, too, but I feared that if I started licking, she’d run out of the room. I felt a sudden impulse, remembering I’d locked the door, but I held back.
"Aren't you looking at the letters? We're supposed to be studying..."
Ah, right.
"I’ve already memorized them."
I’d just glanced at them briefly. They meant 'foot' and 'toes,' I think.
"Hnn... ah♥"
Vera, who had been doubting whether I’d really memorized them, let out a sweet sound when I licked her smooth, hairless calf. I peeled off the paper that said 'calf.'
"Is this really, ah♥, how you study?"
"The five senses include the sense of taste, Teacher."
I couldn't focus on the letters at all. I didn't think I’d be memorizing anything else today. Since it had come to this, I might as well savor Vera’s body to my heart’s content. I’d study less, and the time I spent studying with Vera would increase. It was a win-win. I was sure Vera would come to like it, too.
I climbed up, passing her firm 'thighs.' Vera lived a quiet life far removed from intense exercise, but her soft thighs were mesmerizing. They weren't too thick or too thin—perfectly shaped, elastic, and soft. Every time my wet tongue touched them, Vera flinched at the sensation.
As I climbed all the way up her legs, the black panties covering her pussy came into view. The protagonist always appears last. It wasn't the pussy’s turn yet. I bypassed the panties and headed for her stomach. Passing her slightly rounded, soft lower abdomen, I saw her 'navel,' which sucked in my gaze. Vera, highly aroused by my caresses, was sitting almost as if she were lying down, making her navel stand out even more. It was fascinating to think that Monica had come out of that slender belly.
I pressed my nose to her navel. She must have been scrubbing hard, because there wasn't a single unpleasant scent. When I flicked my tongue against it, her waist jerked—it must have been an erogenous zone. She was such an easy person to read.
Instead of going straight to her breasts, I turned to the side to look at her 'armpit.' Perhaps because she was trying to cover her chest, or perhaps out of shyness, her armpit was tightly folded, showing only the valley of her skin. Not a single hair was out of place; it was perfectly groomed.
"Teacher, I need the armpit textbook."
"Ugh, okay..."
Perhaps because of the excuse of studying, Vera obediently followed my lead. Saying she couldn't lift both arms, she raised her right one, and the breast that had been held by her arm flopped out, attempting an escape. Vera’s left hand clutched her right breast, the pudding-like flesh filling her palm. Just looking at it, I could feel how soft it was.
"Don't look anywhere else, just look at the armpit..."
"Ah, right."
Vera’s armpit was cleanly shaved, without a single hair. It looked like she’d done it recently.
"When did you shave this?"
"This morning, while I was bathing..."
"...Did you shave it because you were seeing me today?"
"That’s not it. I see your face every day... and I groom myself every day anyway..."
I poked her well-groomed, smooth armpit with my tongue. She seemed used to the licking now; she flinched, but there was no violent reaction. Hmm, I wonder how long she can keep that up.
I licked the valley in the middle of her 'back,' moved up to lick the 'nape' of her neck, and sucked on it hard. Her body shuddered, and a suppressed moan escaped her lips.
"Ugh..."
"Teacher. Are you perhaps aroused during class?"
"N-no, I'm not."
"Really? Your panties are already this soaked."
When I pressed my hand against her mound, I could feel the wetness soaking through the fabric. Because I was holding her in a back-hug to touch her back, Vera was trapped in my arms, unable to escape, only able to tremble. Not that her arms were free to use anyway, since she was busy covering her breasts.
"A teacher doesn't feel things during class..."
"Well, if you say so, Teacher."
Lick.
"Hyaang!"
When I licked her ear and gave it a light nip, she reacted wildly. Vera seemed to have so many erogenous zones. To think she’d react like this everywhere I touched.
"You’re saying you didn't feel that just now, either?"
"O-of course not...♥"
"Then please continue the lesson, Teacher. We’ve only finished a little over half of the material."
I didn't have the ability to read minds, but I could clearly read the expression on Vera’s face just now. It was the look of
